6.0 EMISSIONS CONTROL PROGRAMS 

6.1 NOx Trading Program 

6.1.1 Description of NOx Trading Program 

The NOx Trading Program is a regional “cap and trade” 

market system for large sources of NOx emissions in the 

eastern United States, including Illinois. It is designed 

to reduce and maintain NOx emissions from the emission 

units covered by the program within a budget to help 

contribute to attainment and maintenance of the ozone 

ambient air quality standard in the multi-state region 

covered by the program, as required by Section 126 of the 

CAA. The NOx Trading Program applies in addition to other 

applicable requirements for NOx emissions and in no way 

relaxes these other requirements. 

Emission units that are subject to the NOx Trading Program 

are referred to as “budget units.” Sources that have one 

or more budget unit subject to the NOx Trading Program are 

referred to as budget sources. 

The NOx Trading Program controls NOx emissions from budget 

units during a seasonal control period from May 1 through 

September 30 of each year, when weather conditions are 

conducive to formation of ozone in the ambient air. (In 

2004, the first year that the NOx Trading Program is in 

effect, the control period will be May 31 through 

September 30.) By November 30 of each year, the allowance 

transfer deadline, each budget source must hold “NOx

allowances” for the actual NOx emissions of its budget 

units during the preceding control period. The USEPA will 

then retire NOx allowances in the source’s accounts in 

amounts equivalent to its seasonal emissions. If a source 

does not have sufficient allowances in its accounts, USEPA 

would subtract allowances from the source’s future 

allocation for the next control period and impose other 

penalties as appropriate. Stringent monitoring procedures 

developed by USEPA apply to budget units to assure that 

actual emissions of NOx emissions are accurately 

determined. 

The number of NOx allowances available for budget sources 

is set by the overall budget for NOx emissions established 

by USEPA. This budget requires a substantial reduction in 

NOx emissions from historical levels as necessary to meet 

air quality goals. In Illinois, separate rules have been 

established for the budget units that are electrical 

generating units (EGU) and for large units at 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

39 

manufacturing plants and institutions (non EGU), like the 

boilers at this source. Under these rules, the allocation 

or share of the NOx allowances for non-EGU is set in an 

amount established by rule [35 IAC Part 217, Appendix E]. 

New budget unit, for which limited operating data may be 

available, may obtain NOx allowances from the new source 

set-aside (NSSA), a portion of the overall budget reserved 

for new budget units. 

In addition to directly receiving or purchasing NOx

allowances as described above, budget sources may transfer 

NOx allowances from one of their units to another. They 

may also purchase allowances in the marketplace from other 

sources that are willing to sell some of the allowances 

that they have received. Each budget source must 

designate an account representative to handle all its 

allowance transactions. The USEPA, in a central national 

system, will maintain allowance accounts and record 

transfer of allowances among accounts. 

The ability of sources to transfer allowances will serve 

to minimize the costs of reducing NOx emissions from 

budget units to comply with the overall NOx budget. In 

particular, the NOx emissions of budget units that may be 

most economically controlled will be targeted by sources 

for further control of emissions. This will result in a 

surplus of NOx allowances from those units that can be 

transferred to other units at which it is more difficult 

to control NOx emissions. Experience with reduction of 

sulfur dioxide emissions under the federal Acid Rain 

program has shown that this type of trading program not 

only achieves regional emission reductions in a more costeffective manner but also results in greater overall 

reductions than application of traditional emission 

standards to individual emission units. 

The USEPA developed the plan for the NOx Trading Program 

with assistance from affected states. Illinois’ rules for 

the NOx Trading Program are located at 35 IAC Part 217, 

Subpart U and W, for non-EGUs and EGUs, respectively. 

These rules have been approved by the USEPA. These rules 

provide for interstate trading, as mandated by Section 9.9 

of the Act. Accordingly, these rules refer to and rely 

upon federal rules at 40 CFR Part 96, which have been 

developed by USEPA for certain aspects of the NOx Trading 

Program, and which an individual state must follow to 

allow for interstate trading of allowances.

6.1.3 General Provisions of the NOx Trading Program 

a. This source and the budget units at this source shall 

comply with all applicable requirements of Illinois’ 

NOx Trading Program, i.e., 35 IAC Part 217, 

Subpart U, and 40 CFR Part 96 (excluding 40 CFR 

96.4(b) and 96.55(c), and excluding 40 CFR 96, 

Subparts C, E and I), pursuant to 35 IAC 217.456(a) 

and 217.456(f)(2). 

b. Any provision of the NOx Trading Program that applies 

to a budget source (including any provision 

applicable to the account representative of a budget 

source) shall also apply to the owner and operator of 

such budget sources and to the owner and operator of 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

41 

each budget unit at the source, pursuant to 35 IAC 

217.456(f)(3). 

c. Any provision of the NOx Trading Program that applies 

to a budget EGU (including any provision applicable 

to the account representative of a budget unit) shall 

also apply to the owner and operator of such budget 

unit. Except with regard to requirements applicable 

to budget units with a common stack under 40 CFR 96, 

Subpart H, the owner and operator and the account 

representative of one budget unit shall not be liable 

for any violation by any other budget unit of which 

they are not an owner or operator or the account 

representative, pursuant to 35 IAC 217.456(f)(4). 

6.1.4 Requirements for NOx Allowances 

a. Beginning in 2004, by November 30 of each year, the 

allowance transfer deadline, the account 

representative of each budget unit at this source 

must hold allowances available for compliance 

deductions under 40 CFR 96.54 in the budget unit’s 

compliance account or the source’s overdraft account 

in an amount that shall not be less than the budget 

unit’s total NOx emissions for the preceding control 

period (rounded to the nearest whole ton), as 

determined in accordance with applicable monitoring 

requirements, plus any number of allowances necessary 

to account for actual utilization (e.g., for testing, 

start-up, malfunction, and shut down) under 40 CFR 

96.42(e) for the control period, pursuant to 35 IAC 

217.456(d)(1). For purposes of this requirement, an 

allowance may not be utilized for a control period in 

a year prior to the year for which the allowance is 

allocated, pursuant to 35 IAC 217.456(d)(4). 

b. The account representative of a budget unit that has 

excess emissions in any control period, i.e., NOx

emissions in excess of the number of NOx allowances 

held as provided above, shall surrender allowances as 

required for deduction under 40 CFR 96.54(d)(1), 

pursuant to 35 IAC 217.456(f)(5). In addition, the 

owner or operator of a budget unit that has excess 

emissions shall pay any fine, penalty, or assessment, 

or comply with any other remedy imposed under 40 CFR 

96.54(d)(3) and the Act, pursuant to 35 IAC 

217.456(f)(6). Each ton of NOx emitted in excess of 

the number of NOx allowances held as provided above 

for each budget unit for each control period shall 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

42 

constitute a separate violation of 35 IAC Part 217 

and the Act, pursuant to 35 IAC 217.456(d)(3). 

c. An allowance allocated by the Illinois EPA or USEPA 

under the NOx Trading Program is a limited 

authorization to emit one ton of NOx in accordance 

with the NOx Trading Program. As explained by 35 IAC 

217.456(d)(5), no provisions of the NOx Trading 

Program, the budget permit application, the budget 

permit, or a retired unit exemption under 40 CFR 96.5 

and no provision of law shall be construed to limit 

the authority of the United States or the State of 

Illinois to terminate or limit this authorization. 

As further explained by 35 IAC 217.456(d)(6), an 

allowance allocated by the Illinois EPA or USEPA 

under the NOx Trading Program does not constitute a 

property right. As provided by 35 IAC 217.456(d)(2), 

allowances shall be held in, deducted from, or 

transferred among allowances accounts in accordance 

with 35 IAC Part 217, Subpart U, and 40 CFR 96, 

Subparts F and G. 

6.1.5 Monitoring Requirements for Budget Units 

a. The Permittee shall comply with the monitoring 

requirements of 40 CFR Part 96, Subpart H, for the 

budget unit and the compliance of the budget unit 

with the emission limitation under Condition 6.1.4(a) 

shall be determined by the emission measurements 

recorded and reported in accordance with 40 CFR 96, 

Subpart H, pursuant to 35 IAC 217.456(c)(1) and 

(c)(2). 

b. The account representative for the source and the 

budget unit at the source shall comply with those 

sections of the monitoring requirements of 40 CFR 96, 

Subpart H, applicable to an account representative, 

pursuant to 35 IAC 217.456(c)(1). 

Note: Pursuant to 40 CFR 96.70(b), new budget units that 

commence operation before January 1, 2003 are to begin 

complying with applicable monitoring requirements of 40 

CFR Part 96 at least one year in advance of the start of 

the first control period governed by the NOx Trading 

Program. 

Note: Pursuant to 40 CFR 96.70(b), existing budget units 

are to begin complying with applicable monitoring 

requirements of 40 CFR Part 96 at least one year in

217.456(e)(2). 

b. Notwithstanding the provisions for CAAPP permits, 

these submittals need only be signed by the 

designated representative, who may serve in place of 

the responsible official for this purpose, as 

provided by Section 39.5(1) of the Act, and 

submittals to the Illinois EPA need only be made to 

the Illinois EPA, Air Compliance Section. 

6.1.8 Allocation of NOx Allowances to Budget Units 

a. As the budget units identified in Condition 6.1.2(a) 

are “new” units and are not listed in 35 IAC Part 

217, Appendix E, these units are not entitled to an 

allocation of NOx allowances pursuant to 35 IAC 

217.462 and 217.466(a). 

b. i. As the budget units identified in Condition 

6.1.2(a) are “existing” units listed in 35 IAC 

Part 217, Appendix E, these units are entitled 

to NOx allowances as specified by Appendix E, 

subject to transfers of allowances from the 

source made in accordance with 35 IAC 

217.462(b). (The portion of Appendix E that 

applies to the Permittee is provided in 

Condition 6.1.12.) The number of NOx

allowances actually allocated for these budget 

units shall be the number of NOx allowances 

allocated by the Illinois EPA in accordance 

with 35 IAC 217.466(a) and issued by USEPA, 

which may reflect adjustments to the overall 

allocations to budget units as provided for by 

35 IAC 217.460 and 217.462(c). 

ii. To the extent that NOx allowances remain in 

the NSSA after any allocation for new budget 

units, the Permittee is also entitled to a 

pro-rata share of such remaining allowances as 

provided by 35 IAC 217.466(d). 

6.1.9 Eligibility to Obtain NOx Allowances from the New Source 

Set-Aside (NSSA) 

a. In 2004, the Permittee is eligible to obtain NOx

allowances from the NSSA for the budget units 

identified in Condition 6.1.2(a), as provided by 35 

IAC 217.468, because the units are “new” budget 

units.

45 

b. The Permittee is not eligible to obtain NOx

allowances from the NSSA for the budget units 

identified in Condition 6.1.2(a), as provided by 35 

IAC 217.468, because the units are “existing” budget 

units. 

6.1.10 Eligibility for Early Reduction Credits (ERC) 

The Permittee is not eligible to request NOx allowances 

for the budget units identified in Condition 6.1.2(a) for 

any early reductions in NOx emissions, as provided by 35 

IAC 217.470, because these units are new units. 

The Permittee is not eligible to request NOx allowances 

for the budget units identified in Condition 6.1.2(a) for 

any early reductions in NOx emissions prior to the 2004 

control period, as provided by 35 IAC 217.470, because 

these units are not equipped with continuous emission 

monitoring systems for NOx. 

a. The Permittee did not request NOx allowances for the 

budget units identified in Condition 6.1.2(a) for 

early reductions in NOx emissions in the 2001 control 

period in accordance with 35 IAC 217.470. 

b. i. The Permittee may pursue NOx allowances for 

early reductions in NOx emissions, i.e., 

reductions made during the 2002 and 2003 

control period, as provided by 35 IAC 217.470. 

ii. For the purpose of any such request, the NOx

emissions must have been reduced by 30 percent 

or more below the actual emission rate of 

these budget units for the first control 

period in which credit is requested, pursuant 

to 35 IAC 217.470(c)(1). 

6.1.11 Budget Permit Required by the NOx Trading Program 

a. For this source, this segment of the CAAPP Permit, 

i.e., Section 6.1, is the Budget Permit required by 

the NOx Trading Program and is intended to contain 

federally enforceable conditions addressing all 

applicable NOx Trading Program requirements. This

7.0 UNIT SPECIFIC CONDITIONS 

7.1 Corn Processing 

7.1.1 Description 

Milling Process: Clean corn from the elevator at the West 

Plant is conveyed to the mill. Upon arriving in the mill 

the corn is subjected milling and separations. 

Milling: Clean corn from the elevator is steeped in tanks 

containing hot, acidic water. Adding SO2 to water 

produces the steep water. After steeping the corn is 

subjected to a series of milling operations designed to 

separate fiber and germ from the corn kernels. The 

milling equipment consists of a variety of tanks, screens 

and closed hydraulic equipment. Vents from all of the 

process tanks are ducted to a common scrubber to reduce 

fugitive SO2 emissions. 

Separation: After separation of the germ and the fiber 

the process stream consists of a mixture of starch, gluten 

and mill water. Gluten is separated from starch by a 

series of centrifugal operations and both the gluten and 

the starch are further concentrated. The majority of the 

separations equipment is enclosed. 

North and South Feedhouse: The germ, fiber and gluten are 

transported to the North and South Feedhouse. The starch 

is transported to the refinery, ethanol production and 

other process areas. 

The germ slurry is dewatered, dried and either conveyed to 

the corn oil refinery or is loaded out. 

The gluten slurry is dewatered, dried and is transported 

to storage and loadout. 

The fiber slurry is dewatered and dried. Heavy steep 

water is combined with the fiber at various points in the 

drying process. The dried feed is conveyed to the pellet 

mills, ground, treated with steam and then pelletized. 

The pellets discharge from the pellet mills to the pellet 

coolers, where it is then stored and loaded out.

7.2 Alcohol 

7.2.1 Description 

Alcohol is produced from starch in the following 

operations: 

Propagation: Yeast is produced in the propagation step. 

Each propagator is seeded with fresh yeast at staggered 

intervals. The yeast multiplies and matures and is later 

added in the fermentation step. 

Fermentation: Mash (starch, light steep water, stillage 

and yeast) is fermented to produce beer. The alcohol 

concentration increases as the mixture passes through a 

series of fermenters. 

Distillation: The beer is directed to the 190-

distillation process. In this process 190 alcohol, 

stillage and fusel oil are produced. 190 proof alcohol is 

transported to the 200 proof dehydration process where the 

remaining 5% of water is removed. 

Evaporation: Stillage is evaporated in MR evaporators and 

piped to the feed house. 

Ethanol Storage and Loadout: There are several storage 

tanks for steep water, stillage, ethanol, fusel oil, 

denaturant and various other tanks. The alcohol is 

filtered and loaded into either truck or rail. 

CO2 Production: CO2 is a byproduct of the fermentation 

process. The CO2 is collected, compressed and is purified 

by passing it through zinc columns, carbon columns, 

filters and dryer columns. The CO2 is stored prior to 

loadout.

7.7 Bioproducts 

7.7.1 Description 

Astaxanthin: Phaffia yeast, which contains the carotenoid 

astaxanthin, is produced via fermentation. Yeast cells 

are recovered from the fermentation broth, concentrated 

and dried in a natural gas fired spray drier. Dried 

product is removed from the air stream in a series of 

cyclones: particulate emissions are controlled by a 

baghouse containing fabric filters. The dried astaxanthin 

is then packaged for distribution; particulate emissions 

during packaging are controlled by a baghouse containing 

fabric filters. 

Lactic Acid: The lactic acid finishing process involves 

purifying food grade lactic acid through esterification, 

distillation and rehydration. Purified lactic acid is the 

main product of this process. The esterification process 

results in ethyl lactate, which is also loaded out as a 

product. 

Crystalline Sorbitol: Sorbitol liquor is transferred from 

the Corn Processing Plant refinery, dried, sifted, 

packaged and loaded out. Particulate emissions are 

controlled by a baghouse. 

Lysine/Ammonium Sulfate: Lysine is one of the nine 

essential amino acids that cannot be synthesized within 

the body, and therefore, must be consumed in some form. 

Lysine is manufactured by continuously spraying a solution 

of aqueous lysine into fourteen parallel, steam heated, 

fluidized bed spray dryers. The remaining product is 

removed from the dryer exhaust by a fabric filter, which 

is built into the top of each of the dryers. The dried 

lysine is then cooled, screened and packaged. Particulate 

matter emissions during the cooling, screening and 

packaging operations are controlled by baghouse with 

fabric filters. 

Threonine: Threonine is one of the nine essential amino 

acids that cannot be synthesized within the body, and 

therefore, must be consumed in some form. Threonine is 

produced via fermentation. Threonine is recovered from 

the fermentation broth, concentrated and purified. The 

recovered threonine crystal is then dried in steam heated 

fluidized bed dryers, screened and packaged. Particulate 

emissions during the drying, screening and packaging 

operations are controlled by baghouse with fabric filters.

Xanthan Gum: Xanthan Gum is a synthetic, water-soluble 

bipolymer made by fermentation of carbohydrates. It has 

many uses in the food and pharmaceutical fields, 

especially in the prepared mixed and high-protein fast 

foods. 

Xanthan Gum is precipitated from the fermentor broth, 

prior to drying in the closed loop, steam heated dryer. 

The drying process is sealed except for a small vent that 

is scrubbed for isopropanol (IPA) emissions by a packed 

bed scrubber. In addition to the dryer vent, IPA process 

tanks and three distillation columns are vented to the 

packed bed scrubber. The distillation columns are used to 

distill a 60% IPA azeotrope to 85 % purity. 

Xanthan Gum from the closed loop dryer is then milled, 

screened and blended. The processed Xanthan Gum can be 

packaged at this point or can be packaged after being 

agglomerated as either food grade or industrial grade 

Xanthan Gum.

7.10 Grain Preparation 

7.10.1 Description 

The Grain Preparation area is used to prepare the soybean 

for the solvent extraction process. Following initial 

screening and scrap separation, the soybeans are heated in 

a fluidized bed steam dryer followed by the cracking and 

separation of the bean from the hull. The preparation 

processes has aspiration systems and collectors designed 

to separate the beans from the hull. Following the hot 

bean aspiration system, beans are rolled into flakes and 

transferred to the extraction system. Rotexes and 

aspirators further separate the hulls. Grinding is 

followed by pelleting and pellet cooling of the hull 

pellets, which are then transferred to bulk loadout tanks. 

Elevator B consists of process legs primarily designed for 

the handling of numerous products from the processing of 

soy flakes throughout the East Complex. The emissions 

from this area include particulate matter generated from 

three baghouses that aspirate and collect dust from the 

legs, conveyors, bins and blow lines.

7.11 Soybean Extraction and Oil Refining 

7.11.1 Description 

After soy meat is separated from the hulls, the soy oil is 

extracted from the flakes. The soybean flakes from the 

grain preparation process go through the extractor and to 

either the desolventizer toaster dryer cooler 

(conventional flakes) process line or any of the specialty 

flake desolventizing lines. After the flakes are 

processed they can be sifted and ground and transferred to 

Elevator B. The main emissions from this are particulate 

matter emissions from the dryers, five coolers and meal 

sifters and grinders. The extraction process is also the 

source of hexane emissions. The oil refinery consists of 

numerous processes intended to refine the soybean oil.

7.17 Soybean Processing 

7.17.1 Description 

The soybean processing area processes the soybean and 

separates the soybean meat from the soybean hull and the 

other scraps. The soybean meat is used in the extraction 

area, while the hulls are further processed and used in 

other products. Following initial screening and scrap 

separation the soybeans are conditioned in the fluidized 

bed steam dryer followed by the cracking and separation of 

the bean meat from the hull. The preparation process has 

aspiration systems and collectors designed to capture the 

hulls after they have been separated from the soybean 

meat. The bean meats are rolled into flakes prior to 

passing through the expander/cooler system. The expanded 

soybean flakes are then transferred into the extraction 

process. The hulls are further processed by rotexes, 

aspirators, toasters and grinders prior to being 

transferred into pelletizing and storage operations.

Crude oil is degummed and bleached. Other oils may be 

added and the mixture is then deodorized. The edible oils 

are then sent to storage and loadout. In addition oil 

from the corn dewax process may be hydrogenated and then 

sent with the other oils to the deodorizer. Hydrogen gas 

is also produced in this process area with the use of two 

natural gas-fired hydrogen reformers. This process

7.26 Vitamin E 

7.26.1 Description 

The Vitamin E tank farm consists of four fixed roof 

methanol tanks and six fixed roof solvent (heptane) tanks. 

The solvent tanks and the purification and solvent 

recovery processes are vented to a mineral oil scrubber. 

Isopropyl alcohol (IPA) is added to the product after it 

is purified and the excess solvent is recovered. This 

product (succinate) is then sent through grinding and 

packaging processes which are controlled by a baghouse. 

Another product (sterols) is produced by prilling and 

packaging the mixture which leaves the distillation and 

stripping. The prilling and packaging processes are 

controlled by a baghouse.

Subject: Oxidizer System For Wet Corn Mill Feed Dryer #6 

Date Issued: April 28, 2004 

Location: 4666 Faries Parkway, Decatur 

This Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of a 

regenerative thermal oxidizer (RTO) system on the #6 feed dryer system, as 

described in the above referenced application. This Permit is subject to 

standard conditions attached hereto and the following special condition(s): 

1.1 Description 

Archer Daniels Midland (ADM) has requested a construction permit to 

install an oxidizer system (two oxidizer units in parallel) to further 

control emissions from a feed dryer (Dryer #6) in the wet corn mill 

(mill) at its Decatur manufacturing complex. The dryer produces cattle 

feed from ADM by-products and the material that remains after the 

starch, oil and gluten are removed from corn. In the future, emissions 

from the dryer would be controlled by a multi-stage control system, 

including cyclones, wet scrubbing, and the proposed regenerative 

thermal oxidizers (RTO). The new RTO is an emission reduction project 

required by a Consent Decree entered into by the Permittee with the 

United States and State of Illinois, in the United State District Court 

for the Central District of Illinois, United States, v. Archer Daniels 

Midland Company, Civil Action No. 03-2066. The new RTO would 

significantly reduce emissions of VOM and CO from Dryer #6. When the 

RTO’s are installed, ADM intends to remove the existing packed tower 

scrubber from the dryer. The RTO’s are designed for on-line bakeout.

reporting requirements in Conditions 1.9, 1.10 and 1.13 may be 

revised and relaxed by the Illinois EPA in the CAAPP Permit 

issued to the source. 

1.8 Emission Testing Requirements 

a. i. Within 180 days of startup of the affected dryer (i.e. 

Dryer #6 with oxidizer), the Permittee shall have PM, NOx, 

SO2, CO and VOM emissions and opacity from the dryer and 

the destruction efficiency of the oxidizer system for CO 

and VOM measured at its expense by an approved testing 

service, during full load operation of the dryer and other 

conditions representative of normal operation to verify 

compliance with the requirements of this permit. In 

addition, if the Permittee is relying on control 

efficiency for SO2 as provided in Condition 1.6(a)(iii) 

the Permittee shall also measure SO2 at an appropriate 

location in the ductwork prior to the SO2 wet scrubbing 

system used for SO2 control. 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

1-12 

ii. Emission measurements shall also be conducted upon written 

request from the Illinois EPA. For this purpose, the 

Permittee need not conduct measurements prior to the 

control system for SO2, VOM or CO as appropriate, unless 

it will be relying upon control efficiency to demonstrate 

compliance. 

b. i. The following testing methods and procedures shall be 

used, as further specified in Section 9.0 of the Control 

Technology Plan. Refer to 40 CFR 60, Appendix A for USEPA 

test methods. 

Location of Sample Points USEPA Method 1

Moisture USEPA Method 4 

Particulate Matter (PM/PM10) USEPA Method 5/202 

Sulfur Dioxide (SO2) USEPA Method 6/6c 

Opacity USEPA Method 9 

Carbon Monoxide (CO) USEPA Method 10 

Nitrogen Oxides (NOx) USEPA Method 7E 

Volatile Organic Material (VOM) USEPA Method 18 and 25 or 

25A 

ii. Due to the high moisture levels in the exhaust from the 

feed dryers, USEPA particulate matter10 (PM10) test methods 

are not considered reliable and are not being required to 

measure PM10. 

iii. A. The outlet compliance testing location shall be 

located prior to the stack at a point prior to the 

commingling of the #5 and #6 dryers exhaust streams 

but after the Dryer #6 oxidizer. 

B. Subsequent permits issued by the Illinois EPA may 

establish provisions to allow measurements to be 

conducted in the stack, based on the combined 

emissions of the #5 and #6 dryers. In conjunction 

with the issuance of such a permit, separate 

measurements of the emissions of each dryer and the 

combined emissions of the dryers at the point of 

discharge maybe required, as needed to assure that 

downstream equipment does not add to the emissions as 

discharged to the atmosphere. 

c. Outlet testing and control efficiency testing will be 

based on either Method 25 or Method 25A calibrated to 

propane, whichever is applicable depending on 

concentration (i.e., Method 25 shall be used on both 
CAAPP PERMIT

the inlet and outlet when the outlet total 

hydrocarbon concentration is > 50 ppm as carbon and 

Method 25A shall be used on both the inlet and outlet 

when the outlet THC concentration is < 50 ppm as 

carbon). 

c. The Permittee shall submit a written test plan to the Illinois 

EPA for review and approval for the initial testing and if a 

significant change in the procedures for this testing is planned 

from the procedures followed in the previous test. This plan 

shall be submitted at least 60 days prior to the actual date of 

testing and include the following information as a minimum: 

i. A description of the planned test procedures. 

ii. The person(s) who will be performing sampling and analysis 

and their experience with similar tests. 

iii. The specific conditions under which testing will be 

performed, including a discussion of why these conditions 

will be representative of maximum emissions. 

iv. The specific points at which samples will be taken for a 

pollutant. (Note: For future measurements, if sampling 

will be conducted at the stack, or other point that 

includes the exhaust from other dryers, rather than after 

control units, the plan must also address the approach 

being taken for showing compliance, e.g., all dryers will 

comply with a PM limit of 0.010 gr/scf.) 

d. The Permittee shall notify the Illinois EPA prior to conducting 

these measurements to enable the Illinois EPA to observe testing. 

Notification for the expected date of testing shall be submitted 

a minimum of 30 days prior to the expected date. Notification of 

the actual date and expected time of testing shall be submitted a 

minimum of 5 working days prior to the actual date of the test. 

The Illinois EPA may accept shorter advance notice if it does not 

interfere with the Illinois EPA’s ability to observe testing. 

e. Copies of the Final Report(s) for these tests shall be submitted 

to the Illinois EPA within 30 days after the test results are 

compiled and finalized. These reports shall include as a 

minimum:

Decatur, Illinois 62526 

Application No.: 03020027 I.D. No.: 115015AAE 

Applicant's Designation: DRYER #5 Date Received: May 11, 2004 

Subject: Wet Corn Mill Feed Dryer #5 

Date Issued: July 28, 2004 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of a 

regenerative thermal oxidizer (RTO) on the #5 feed dryer system as described 

in the above referenced application. This Permit is subject to standard 

conditions attached hereto and the following special condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) and 

to operate the #5 feed dryer system with a control system that includes an 

RTO to construct the above referenced project, in that the Illinois 

Environmental Protection Agency (Illinois EPA) finds that the application 

fulfills all applicable requirements of 40 CFR 52.21. This approval is 

issued pursuant to the Clean Air Act, as amended, 42 U.S.C. 7401 et. seq., 

the Federal regulations promulgated thereunder at 40 CFR 52.21 for Prevention 

of Significant Deterioration of Air Quality (PSD), and a Delegation of 

Authority agreement between the United States Environmental Protection Agency 

and the Illinois EPA for the administration of the PSD Program. This 

approval becomes effective in accordance with the provisions of 40 CFR 124.15 

and may be appealed in accordance with the provisions of 40 CFR 124.19. This 

approval is also based upon and subject to the following findings and the 

conditions, which follow: 

1. Archer Daniels Midland (ADM) has requested a construction permit to 

install an oxidizer to further control emissions from feed dryer (Dryer 

#5) in the wet corn mill (mill) at its Decatur manufacturing complex. 

The dryer produces cattle feed from ADM by-products and the material 

that remains after the starch, oil and gluten are removed from corn. 

Emissions from the dryer would be controlled by a multi-stage control 

system, including cyclones, wet scrubbing, and the proposed 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

1-21 

regenerative thermal oxidizer (RTO). The new RTO would significantly 

reduce emissions of VOM and CO from Dryer #5. 

2. The source is located in Decatur Township in Macon County. The area is 

designated attainment for all pollutants. 

3. The project is subject to PSD review for particulate matter (PM10), 

volatile organic material (VOM), and carbon monoxide (CO) because Dryer 

#5 has emitted significant amounts of PM, VOM, and CO, i.e., more than 

15, 40, and 100 tons/year respectively, without the proposed RTO and 

ADM has not previously obtained a PSD permit for the dryer that 

addressed significant emissions of these pollutants. The permit would 

now limit annual PM, VOM, and CO emissions to 13.5, 27.7, and 67.6 tons 

respectively from Dryer #5. At these levels, the dryer would no longer 

be a significant source of emissions so that an analysis of air quality 

impacts is not required. 

4. After reviewing the materials submitted by ADM, the Illinois EPA has 

determined that the project, as proposed, would (i) be in compliance 

with applicable Board emission standards and (ii) utilize Best 

Available Control Technology (BACT). 

5. The Illinois EPA has determined that the project, as proposed, would 

comply with all applicable Illinois Air Pollution Board Regulations and 

the federal Prevention of Significant Deterioration of Air Quality 

Regulations (PSD), 40 CFR 52.21. 

6. A copy of the application and a summary of the Illinois EPA’s review of 

the application and a draft of this permit were placed in a location in 

the vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing this approval subject to the following conditions 

and consistent with the specifications and data included in the application. 

Any departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization by Illinois 

EPA. 

Standard Conditions 

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply, unless 

superseded by the following special conditions. 

Best Available Control Technology 

2a. i. Dryer #5 shall be equipped, operated, and maintained with a 

multi-stage control system consisting of cyclones, wet scrubbing 

and regenerative thermal oxidization (RTO). The control system 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-22 

shall be operated and maintained in conformance with good air 

pollution control practices. 

ii. The PM emission control system shall be designed, constructed, 

and maintained to achieve PM emission rate from Dryer #5 that is 

no more than 0.010 gr/dscf. For this purpose, PM shall be 

determined as filterable particulate matter, as measured by USEPA 

Method 5 (See also Condition 5). 

 b. The RTO system shall be designed, constructed, and maintained to comply 

with the following limits: 

i. At least 90 percent destruction of CO by mass, (comparing the CO 

in the inlet and outlet of the system) or a CO emission rate from 

Dryer #5 that is no more than 100 ppm; and 

ii. At least 95 percent destruction of VOM by mass (comparing the VOM 

in the inlet and outlet of the system) or a VOM emission rate 

from Dryer #5 that is no more than 10 ppm, as expressed as 

propane. 

Condition 2 addresses Best Available Control Technology, for PM, CO and 

VOM emissions as required by Section 165 of the Clean Air Act. These 

requirements and the emission limits in Condition 3 take effect after 

initial shakedown of the RTO is completed, which period shall end 180 

days after initial startup of the dryer with the RTO unless extended by 

the Illinois EPA. 

3. Limitations 

a. Dryer #5 shall be equipped, operated, and maintained with low NOx

natural gas or biogas-fired burner. The burners shall be 

operated and maintained in conformance with good air pollution 

control practices. 

b. Emissions of PM, SO2, CO, VOM and NOx from Dryer #5 shall not 

exceed the following limits: 

i. PM – 3.1 lb/hour and 13.5 tons/year. 

ii. NOx, (including the contribution from the RTO burner) – 

8.0 lb/hour and 35 tons/year. 

iii. SO2 – 7.1 lb/hour and 30.9 tons/year. 

iv. CO – 15.4 lb/hour and 67.6 tons/year. 

v. VOM – 6.3 lb/hour and 27.7 tons/year. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038

c. This permit is issued based on Dryer #5 not being subject to PSD 

for SO2 or NOx because emissions of SO2 and NOx are less than the 

significant emission rate threshold. 

d. This permit does not authorize changes to the mill that are 

unrelated to Dryer #5 that would increase the mill’s capacity. 

4. Good Operating Practices 

The Permittee shall operate, maintain, and repair Dryer #5 and its 

control system in a manner that is consistent with the following: 

a. Operating Procedures for Control System: Written operating 

procedures shall be developed and maintained describing normal 

air pollution control equipment operation, including startup and 

shutdown. Such procedures shall include maintenance practices 

and may incorporate the manufacturers recommended operating 

instructions. 

b. Operating Procedures for Burner: Written operating practices 

shall be developed and maintained, including establishment of 

target levels for the following operating parameters for the low 

NOx burner: 

i. Furnace Temperature Operating Range. 

ii. Combustion Air Fan Amperage. 

iii. Recirculated Air Damper Position and Secondary Air. 

c. Inspections: Visual inspections of Dryer #5 and its air 

pollution control and monitoring equipment shall be conducted on 

at least a weekly basis. 

d. Repairs: Prompt repairs shall be made upon identification of 

need either as a consequence of formal inspections or other 

observations in conformance with good air pollution control 

practice. 

e. Records: Records of inspection, maintenance, and repair 

activities for all equipment shall be kept on site and shall 

include as a minimum: 

i. Date of inspection, maintenance, and repair activities.

These requirements and related monitoring, recordkeeping and reporting 

requirements in Conditions 6, 7 and 9 may be revised and relaxed by the 

Illinois EPA in the CAAPP Permit issued to the source. 

5. Emission Testing Requirements 

a. i. Within 180 days of startup of the Dryer #5 RTO the 

Permittee shall have PM, NOx, SO2, CO and VOM emissions and 

opacity from Dryer #5 and the destruction efficiency of 

the RTO system for CO and VOM measured at its expense by 

an approved testing service, during full load operation of 

the dryer and conditions which are representative of 

maximum emissions to verify compliance with the 

requirements of this permit. In additions, if the 

Permittee is relying on destruction efficiency for CO or 

VOM, as provided in Condition 2(b)(i) or (ii) the 

Permittee shall also measure CO or VOM, as appropriate, at 

the inlet to the RTO. 

ii. Emission measurements shall also be conducted upon written 

request from the Illinois EPA.

14. As a consequence of the above conditions, this permit is issued based 

upon the construction and operation of the expansion covered by this 

permit not constituting a major modification subject to 40 CFR 52.21, 

Prevention of Significant Deterioration (PSD). 

a. There have been and will be accompanying decreases in emissions 

of particulate matter such that the net change in emissions is 

less than significant, i.e., less than 15 tons/year increase. 

Specifically, accompanying this project, the Permittee will 

reduce emissions of particulate matter from roadways at the 

source as addressed by Condition 4(a) and 4(b)(i), such that 

there is not a significant increase in particulate matter 

emissions. The net change is estimated at 83.0 tons/year 

decrease, as addressed by Tables 1a, 1b, 1c and 1d. In addition, 

the Permittee will be further reducing particulate matter 

emissions by sweeping portions of Faries Parkway and Samuel 

Street that connect the Permittee's operations, with an estimated 

decrease of 92.7 tons/year. 

b. There have been and will be accompanying decreases in emissions 

of sulfur dioxide such that the net change in emissions is less 

than significant, i.e., less than 40.0 tons/year increase. 

Specifically, accompanying this project, the Permittee will 

reduce emissions from existing equipment by adding caustic to the 

scrubbant in existing scrubbers, connecting the sulfur burner 

exhaust to the mill house scrubber, and then connecting the mill 

house exhaust to a germ dryer scrubber, as further described in 

the application. As a result, there is not a significant 
CAAPP PERMIT

increase in sulfur dioxide emissions. The net change is 

estimated at 244 tons/year decrease, as summarized in Table 2b. 

c. The increase in nitrogen dioxide emissions accompanying the 

expansion is less than significant, i.e., less than 40 tons/year. 

The potential increase in emissions is estimated to be 39.4 

ton/year of nitrogen oxide as summarized in Table 3a. 

d. The increase in carbon monoxide emissions is not significant, as 

the increase is less than 100 tons per year. 

15. The Permittee shall evaluate in accordance with a written plan reviewed 

in advance by the Agency, the configuration and operating parameters of 

the feed dryers and their control system as related to odors. An 

initial evaluation shall be completed by July 1, 1997. 

16. This permit becomes effective upon dismissal of permit appeal PCB 92-

109 by the Pollution Control Board.

Application No.:00090052 I.D. No.: 115015AAE 

Applicant's Designation: ALCOHOL PSD Date Received: June 7, 2004 

Subject: Ethyl Alcohol Production 

Date Issued: July 28, 2004 Expiration Date: March 28, 2008 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT and 

OPERATE emission source(s) and/or air pollution control equipment consisting 

of an expansion of the alcohol production plant with installation of 

additional air pollution control equipment and the equipment listed in 

Attachment A as described in the above referenced application. This Permit 

is subject to standard conditions attached hereto and the following special 

condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct and operate the above referenced project, in that the Illinois 

Environmental Protection Agency (Agency) finds that the application fulfills 

all applicable requirements of 40 CFR 52.21. This approval is issued 

pursuant to the Clean Air Act, as amended, 42 U.S.C. 7401 et. seq., the 

Federal regulations promulgated thereunder at 40 CFR 52.21 for Prevention of 

Significant Deterioration of Air Quality (PSD), and a Delegation of Authority 

agreement between the United States Environmental Protection Agency and the 

Illinois EPA for the administration of the PSD Program. This approval 

becomes effective in accordance with the provisions of 40 CFR 124.15 and may 

be appealed in accordance with the provisions of 40 CFR 124.19. This 

approval is also based upon and subject to the following findings and the 

conditions, which follow: 

1. Archer Daniels Midland (ADM) has requested a joint construction and 

operating permit for the Alcohol Plant (Plant) at its Decatur 

manufacturing complex. The alcohol plant produces fuel ethanol from 

dextrose (corn sugar) that is produced elsewhere at the complex. The 

permit would allow for a greater daily production rate of 1,000,000 

gal/day, monthly average, of ethanol as 200 proof (100%) ethanol. At 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

1-58 

the same time, ADM would install additional control devices to better 

control volatile organic material (VOM) emissions from the plant (refer 

to Attachment D). 

2. The source is located in Decatur Township in Macon county. The area is 

designated attainment for all pollutants. 

3a. The alcohol plant is subject to PSD review for volatile organic 

material (VOM) because: 

i. ADM’s Decatur complex is a major source of emissions; 

ii. The expansion of the alcohol plant has the potential to increase 

emissions of VOM by a significant amount, i.e., more than 40 

tons/year; and 

iii. ADM has not previously obtained a PSD permit for the existing 

alcohol plant. 

 b. This permit is issued based upon the construction and operation of the 

expanded alcohol plant covered by this permit not constituting a major 

modification for the purpose of PSD for pollutants other than VOM. In 

this regard, this permit does not address drying of the residual solids 

from the fermentation process, which are transferred to and constitute 

a minor component in the feed drying operations at the corn wet mill. 

4. After reviewing the materials submitted by ADM, Illinois EPA has 

determined that the plant, as proposed, would (i) be in compliance with 

applicable Board emission standards and (ii) utilize Best Available 

Control Technology (BACT) on emissions of VOM. 

5. The Illinois EPA has determined that the plant, as proposed, would 

comply with all applicable Illinois Air Pollution Board Regulations and

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply unless 

superseded by the following conditions. 

2a. Significant emission units in the alcohol plant emitting VOM, other 

than units with negligible VOM emissions as identified in Attachment B, 

shall be enclosed and ducted through a closed vent system to a VOM 

emission control system as generally designated in Attachment A. 

 b. i. Each VOM emission control system shall be designed and operated 

to achieve at least 95% control of VOM comparing the amount of 

VOM introduced into the control system and the emissions to the 

atmosphere or achieve an outlet concentration of VOM not to 

exceed 20 ppm. These control systems shall be operated and 

maintained in conformance with good air pollution control 

practices. 

ii. Notwithstanding the above: 

A. In the event of a malfunction or breakdown of the CO2

scrubbing system, the affected scrubber may be bypassed in 

order to avoid severe damage to equipment for a period not 

to exceed 12 hours while repairs are attempted. If 

repairs cannot be made within 12 hours, the fermentor 

blend rate shall be reduced to 75% of its maximum 

operating rate. This restriction will remain in effect 

until the control system is once again fully operational. 

B. Outage of the CO2 scrubbing system for scheduled 

preventative maintenance is allowed once in every six 

months for a period of up to 12 hours prior to mandatory 

reduction of fermentor blend rate as set forth in 

Condition 2(b)(ii)(A). 

 c. As an alternative to the above, a storage tank may be equipped, 

operated and maintained with a floating roof that would comply with 40 

CFR 60 Subpart Kb. 

3. Disposition of Collected VOM 

All VOM collected through control systems, i.e. scrubbers or condensers 

effluent stream, shall be managed using best management practices to 

ensure that it is not emitted from another process, before being 

discharged to the waste water treatment plant at the source.

4a. The alcohol plant is subject to 40 CFR 60, Subpart VV, Standards of

that it will begin complying with the VOM limitation in Condition 

8. 

8. Emission Limitations 

a. i. Plant emissions of VOM, other than from leaking 

components, shall not exceed 280 tons per year. This limit 

shall take effect 15 months after completion of the final 

control system (scheduled November 30, 2005) as specified 

in Attachment D, “Control System Installation Timeline”. 

Compliance with this limit shall be determined on a 

rolling 12 month basis, with monthly compliance 

determinations. 

ii. Beginning four months after completion of the final 

control system, plant emissions of VOM, other than from 

leaking components, shall not exceed a pro-rated share of 

the 280 ton annual limitation. For example, in this fourth 

month VOM emissions shall not exceed 1/12 of 280 tons; in 

the fourth and fifth month, VOM emissions shall not exceed 

2/12 of 280 tons. 

Note: The above limits do not include VOM emissions from leaking 

components. 

This permit is issued based on maximum VOM emissions from leaking 

components of 450 tons/year. This determination is based on USEPA’s 

SOCMI emissions estimating methodology and compliance with requirements 

of 40 CFR 60 Subpart VV for inspections, recordkeeping, and repair of 

leaking components. 

b. VOM emissions from individual units (vents) shall not exceed the 

limits in Attachment C. Upon timely request by the Permittee, 

limits for individual units in Attachment C may be revised by the 

Illinois EPA based upon the results of the initial emissions 

testing as required by Condition 9 of this permit provided that 

the combined limits continue to meet the total limit in 

Attachment C. 

9. Emissions Testing 

a. i. Within 90 days of completion of the last control system 

utilizing wet scrubbing (scheduled for November 30, 2005), 

the Permittee shall have the VOM emissions from and

maximum emissions to verify compliance with the 

requirements of this permit. 

ii. The Permittee shall retest these VOM control system at 

least every 5 years, or as established in the CAAPP 

permit. 

iii. Where the inherent design of an existing control system 

makes inlet testing of the control system impractical or 

unreliable, the Illinois EPA may waive testing of inlet 

emissions provided that the Permittee provides information 

to the Illinois EPA that documents achievement of a 

control efficiency of at least 95% for VOM. 

iv. Measurements of VOM emissions from specified emission 

unit(s) shall also be conducted upon reasonable written 

request from the Illinois EPA in accordance with such 

request. 

v. If the Permittee is unable to test at 95% of plant or 

process capacity, an emissions test shall be repeated when 

consistent operation at 95% capacity is achievable. 

b. The following methods and procedures shall be used for emission 

testing. Refer to 40 CFR 60, Appendix A for USEPA test methods. 

Location of Sample Points USEPA Method 1

Subject: Corn Plant Anaerobic Wastewater Treatment 

 System (East Plant) 

Date Issued: October 17, 2003 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of a new 

anaerobic wastewater treatment system consisting of three lagoons with 

covers, two scrubbers (water and caustic) and a flare to control emissions 

from the three lagoons and replacement burners for existing fiber dryers 1-7 

as described in the above-referenced application. This Permit is subject to 

standard conditions attached hereto and the following special condition(s): 

1.0 Unit Specific Conditions 

1.1 Unit: Anaerobic Wastewater Treatment System 

Control: Scrubbers and Flare 

1.1.1 Description 

The Corn Plant Anaerobic Wastewater Treatment System will 

be located at ADM’s East Plant. This new treatment system 

will reduce the load on the existing aerobic lagoons, 

which are currently utilized by the corn plant. The 

system will consist of three lagoons each covered by a 

floating membrane which will capture biogas. The biogas, 

which is mostly methane, is formed by anaerobic digestion 

of solids. The membrane will have channels operating at 

negative pressure which forces the biogas to flow to the 

edges and out through stacks for control. 

The control system will consist of two scrubbers in series 

with the first being a water scrubber and the second being

Application No.: 96030038 

1-77 

a caustic scrubber. After the caustic scrubber, the 

biogas will consist primarily of methane with less than 

200 ppm H2S. 

The scrubbed biogas will be combusted either in the new 

flare or in the existing Fiber Dryers 1-7. The preferred 

disposition of the biogas is to the Fiber Dryers since 

this will reduce the amount of natural gas fired in these 

existing dryers. Nevertheless, this permit allows a 

portion of the potential biogas to be flared. 

The change to the fiber dryers will entail replacing or 

modifying burners with an equal capacity burner that can 

handle the potentially corrosive biogas.

1.1.3 Applicability Provisions and Applicable Regulations 

a. The “affected wastewater treatment system” for the 

purpose of these unit-specific conditions, is the 

wastewater treatment system described in Conditions 

1.1.1 and 1.1.2. 

b. No person shall cause or allow the emission of sulfur 

dioxide into the atmosphere from any process emission 

unit to exceed 2000 ppm [35 IAC 214.301]. 

c. Malfunction and Breakdown Provisions 

In the event of a malfunction or breakdown of a 

scrubber, the Permittee is authorized to continue 

operation of the affected wastewater treatment system 

in violation of the applicable requirement of 35 IAC 

214.301, as necessary to prevent risk of injury to 

personnel or severe damage to equipment. This 

authorization is subject to the following 

requirements: 

i. The Permittee shall repair or replace the 

damaged feature(s) as soon as practicable. 

This shall be accomplished within 96 hours.

1-78 

ii. The Permittee shall fulfill the applicable 

recordkeeping and reporting requirements of 

Conditions 1.1.9(d) and 1.1.10(a). 

1.1.4 Non-Applicability of Regulations of Concern 

a. This permit is issued based on this project not being a 

major modification pursuant to 40 CFR 52.21, Prevention 

of Significant Deterioration (PSD). This determination 

is made based on information provided in the application 

by the Permittee. The limits of this permit are 

established to ensure that this project does not 

constitute a major modification pursuant to PSD. 

For this purpose, the Permittee has shown that there 

will be a negligible increase in emissions of PSD 

pollutants attributable to the installation of the 

new similar burners and consumption of biogas, since 

the combustion of methane is comparable to combustion 

of natural gas. In addition, there will be at most a 

negligible increase in future actual emissions of the 

fiber dryers above baseline actual emissions as a 

result of this project. 

1.1.5 Operational and Production Limits and Work Practices 

a. The control system shall be designed to have the 

following features: 

i. Ability to bypass on or both scrubbers, so 

that biogas can be flared or sent to the 

dryers when the scrubbers are out of service 

for preventative maintenance; and 

ii. Ability to vent biogas to a bladder or other 

containment system capable of holding an 

amount of biogas equivalent to a 5 minute 

release. 

b. At all times, the Permittee shall, to the extent 

practicable, maintain and operate the lagoons, 

including associated air pollution capture and 

control equipment, in accordance with written 

operating procedures that provide for good air 

pollution control practice for minimizing emissions. 

At a minimum, these practices shall include: 

i. The following provision for operation of the 

covers; 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-79 

The digester system shall be vapor tight and 

under negative pressure insuring that all off 

gases are vented through the control system. 

ii. The following provisions for operation of the 

scrubber: 

The scrubbers shall be operated within the 

acceptable operating parameters as determined 

by the stack test required by Condition 1.1.7. 

iii. The following provisions for operation of the 

flare: 

A. The flare shall be operated with a flame 

present at all times. 

B. The presence of a flare pilot flame shall be 

monitored using a thermocouple or other 

comparable device to detect the presence of 

a flame. 

C. If the flame goes out, the flow of biogas to 

the flare shall be discontinued until the 

pilot flame or the main flame is restored, 

unless the flare also is designed to serve as 

the emergency relief stack, in which case the 

flow of biogas may continue as further allowed 

by the malfunction and breakdown provisions of 

this permit. 

iv. Provisions for periodic inspection of the 

covers, scrubbers, and flare. 

c. If the biogas flow rate to the flare exceeds 792 

million cubic feet/year, the Permittee shall submit a 

report to the Illinois EPA identifying the maximum 

amount of biogas that will be flared and 

demonstrating that it can comply with Condition 1.1.6 

when flaring the maximum amount of biogas. 

1.1.6 Emission Limitations 

a. Except during periods of malfunction and breakdown, 

the H2S content of the treated biogas following the 

caustic scrubber (prior to combustion) shall not 

exceed 200 ppm.

total. Emissions of SO2 associated with 

burning biogas in the dryers during 

malfunction or breakdown of the scrubbers 

shall be included when determining compliance 

with this limit. 

iii. This permit is issued based upon negligible 

emissions of particulate matter and volatile 

organic material from the affected wastewater 

treatment system. For this purpose, emissions 

of each pollutant shall not exceed nominal 

emission rates of 0.1 lb/hr and 0.44 tons/yr. 

iv. This permit is issued based on a negligible 

increase in emissions of NOx, CO, VOM, PM/PM10, 

and SO2 associated with burning properly 

scrubbed biogas in the dryers.

monoxide (CO) from the furnaces. In conjunction with this system, ADM 

may also make changes to the existing scrubbing units on the furnaces, 

which control emissions of particulate matter (PM) and sulfur dioxide 

(SO2). 

2. The source is located in Decatur Township in Macon County. The area is 

designated attainment for all pollutants. 

3a. The requested permit would allow annual VOC and CO emissions of 35.0 

and 87.6 tons, respectively, from the three carbon furnaces. 

 b. The two newer furnaces, which were installed in 1981 and 1990, are 

subject to PSD for VOC and CO emissions because they were not 

previously addressed by a PSD permit. The oldest furnace, which was 

installed in 1976, predates the PSD rules. However, because the 

proposed control would also control this furnace, it is also subject to 

the terms and conditions of this permit. 

 c. This permit is issued based on the carbon furnaces not being subject to 

PSD for PM, SO2 and NOx. This is because for these pollutants, the 

emissions of each of the two newer furnaces have been below the PSD 

thresholds for a major modification. Accordingly, as provisions of 

this permit address PM, SO2 or NOx, they are not considered part of the 

PSD approval. 

 d. This permit does not explicitly address emissions of hazardous air 

pollutants from the carbon furnaces, which are expected to greatly 

reduced, along with VOC and CO emissions, by the addition of the new 

control. 

4. After reviewing the materials submitted by ADM, Illinois EPA has 

determined that the operation of the carbon furnaces, as now proposed, 

would (i) be in compliance with applicable Board emission standards and 

(ii) utilize Best Available Control Technology (BACT) on emissions of 

VOC and CO. 

5. The new control system will reduce the VOC and CO emissions and 

associated air quality impacts of the three furnaces to levels below 

those accompanying the operation of the initial furnace, which was 

installed prior to the PSD rules. Accordingly, this project results in 

an improvement in air quality not only compared to current levels but 

also compared to baseline levels when the PSD rules were adopted. 

6. The Illinois EPA has determined that this application complies with all 

applicable Illinois Air Pollution Board Regulations and the federal 

rules for Prevention of Significant Deterioration (PSD), 40 CFR 52.21.

Attn: Pat Dennis 

4666 Faries Parkway 

Decatur, Illinois 62526 

Application No.:00090052 

I.D. No.: 115015AAE 

Applicant's Designation: ALCOHOL PSD 

Date Received: September 21, 2000 

Subject: Ethyl Alcohol Production 

Date Issued: March 28, 2003 

Expiration Date: March 28, 2008 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT and 

OPERATE emission source(s) and/or air pollution control equipment consisting 

of an expansion of the alcohol production plant with installation of 

additional air pollution control equipment and the equipment listed in 

Attachment A as described in the above referenced application. This Permit 

is subject to standard conditions attached hereto and the following special 

condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct and operate the above referenced project, in that the Illinois 

Environmental Protection Agency (Agency) finds that the application fulfills 

all applicable requirements of 40 CFR 52.21. This approval is issued 

pursuant to the Clean Air Act, as amended, 42 U.S.C. 7401 et. seq., the 

Federal regulations promulgated thereunder at 40 CFR 52.21 for Prevention of 

Significant Deterioration of Air Quality (PSD), and a Delegation of Authority 

agreement between the United States Environmental Protection Agency and the 

Illinois EPA for the administration of the PSD Program. This approval 

becomes effective in accordance with the provisions of 40 CFR 124.15 and may 

be appealed in accordance with the provisions of 40 CFR 124.19. This 

approval is also based upon and subject to the following findings and the 

conditions, which follow: 

1. Archer Daniels Midland (ADM) has requested a joint construction and 

operating permit for the Alcohol Plant (Plant) at its Decatur 

manufacturing complex. The alcohol plant produces fuel ethanol from 

dextrose (corn sugar) that is produced elsewhere at the complex. The 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-109 

permit would allow for a greater daily production rate of 1,000,000 

gal/day, monthly average, of ethanol as 200 proof (100%) ethanol. At 

the same time, ADM would install additional control devices to better 

control volatile organic material (VOM) emissions from the plant (refer 

to Attachment D). 

2. The source is located in Decatur Township in Macon county. The area is 

designated attainment for all pollutants. 

3a. The alcohol plant is subject to PSD review for volatile organic 

material (VOM) because: 

i. ADM’s Decatur complex is a major source of emissions; 

ii. The expansion of the alcohol plant has the potential to increase 

emissions of VOM by a significant amount, i.e., more than 40 

tons/year; and 

iii. ADM has not previously obtained a PSD permit for the existing 

alcohol plant. 

 b. This permit is issued based upon the construction and operation of the 

expanded alcohol plant covered by this permit not constituting a major 

modification for the purpose of PSD for pollutants other than VOM. In 

this regard, this permit does not address drying of the residual solids 

from the fermentation process, which are transferred to and constitute 

a minor component in the feed drying operations at the corn wet mill. 

4. After reviewing the materials submitted by ADM, Illinois EPA has 

determined that the plant, as proposed, would (i) be in compliance with 

applicable Board emission standards and (ii) utilize Best Available 

Control Technology (BACT) on emissions of VOM. 

5. The Illinois EPA has determined that the plant, as proposed, would 

comply with all applicable Illinois Air Pollution Board Regulations and 

the federal Prevention of Significant Deterioration of Air Quality 

Regulations (PSD), 40 CFR 52.21. 

6. A copy of the application and the Illinois EPA’s formal review of the 

application and a draft of this permit were placed in a location in the 

vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing this approval subject to the following conditions 

and consistent with the specifications and data included in the application. 

Any departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization by Illinois 

EPA.

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply unless 

superseded by the following conditions. 

2a. Significant emission units in the alcohol plant emitting VOM, other 

than units with negligible VOM emissions as identified in Attachment B, 

shall be enclosed and ducted through a closed vent system to a VOM 

emission control system as generally designated in Attachment A. 

 b. i. Each VOM emission control system shall be designed and operated 

to achieve at least 95% control of VOM comparing the amount of 

VOM introduced into the control system and the emissions to the 

atmosphere or achieve an outlet concentration of VOM not to 

exceed 20 ppm. These control systems shall be operated and 

maintained in conformance with good air pollution control 

practices. 

ii. Notwithstanding the above: 

A. In the event of a malfunction or breakdown of the CO2

scrubbing system, the affected scrubber may be bypassed in 

order to avoid severe damage to equipment for a period not 

to exceed 12 hours while repairs are attempted. If 

repairs cannot be made within 12 hours, the fermenter 

blend rate shall be reduced to 75% of its maximum 

operating rate. This restriction will remain in effect 

until the control system is once again fully operational. 

B. Outage of the CO2 scrubbing system for scheduled 

preventative maintenance is allowed once in every six 

months for a period of up to 12 hours prior to mandatory 

reduction of fermenter blend rate as set forth in 

Condition 2(b)(ii)(A). 

 c. As an alternative to the above, a storage tank may be equipped, 

operated and maintained with a floating roof that would comply with 40 

CFR 60 Subpart Kb. 

3. Disposition of Collected VOM 

All VOM collected through control systems, i.e. scrubbers or condensers 

effluent stream, shall be managed using best management practices to 

ensure that it is not emitted from another process, before being 

discharged to the waste water treatment plant at the source.

4a. The alcohol plant is subject to 40 CFR 60, Subpart VV, Standards of

such earlier date that the Permittee notifies the Illinois EPA 

that it will begin complying with the VOM limitation in Condition 

8. 

8. Emission Limitations 

a. i. Plant emissions of VOM, other than from leaking 

components, shall not exceed 280 tons per year. This limit 

shall take effect 15 months after completion of the final 

control system (scheduled November 30, 2005) as specified 

in Attachment D, “Control System Installation Timeline”. 

Compliance with this limit shall be determined on a 

rolling 12 month basis, with monthly compliance 

determinations. 

ii. Beginning four months after completion of the final 

control system, plant emissions of VOM, other than from 

leaking components, shall not exceed a pro-rated share of 

the 280 ton annual limitation. For example, in this fourth 

month VOM emissions shall not exceed 1/12 of 280 tons; in 

the fourth and fifth month, VOM emissions shall not exceed 

2/12 of 280 tons. 

Note: The above limits do not include VOM emissions 

from leaking components. 

This permit is issued based on maximum VOM emissions from 

leaking components of 450 tons/year. This determination 

is based on USEPA’s SOCMI emissions estimating methodology 

and compliance with requirements of 40 CFR 60 Subpart VV 

for inspections, recordkeeping, and repair of leaking 

components. 

b. VOM emissions from individual units (vents) shall not exceed the 

limits in Attachment C. Upon timely request by the Permittee,

EPA upon a satisfactory showing that an extension is 

justified. This condition supersedes Standard Condition 

1. 

ii. For this purpose, it is expected that the Permittee will 

commence and complete construction no later than the dates 

set forth in Attachment D. Unjustified delays in this 

schedule shall be considered a violation of this Permit. 

b. i. For this purpose, further control of the existing alcohol 

plant and expansion of the alcohol plant shall be 

addressed separately. To “commence construction” of the 

expansion of the plant, the Permittee must commence 

construction on process equipment or control systems whose 

capacity facilitates the expansion of the plant. There 

after, until construction is complete, the Permittee shall 

submit annual reports to demonstrate that a continuous 

program of construction is underway, which reports shall 

describe the various new and replacement units that the 

Permittee has constructed in the last year and that 

intends to construct in the upcoming year. 

ii. This permit shall become invalid as applied to further 

expansion of the alcohol plant if construction is 

discontinued for a period of 18 months or more, or if 

construction is not completed within a reasonable period 

of time.

PERMITTEE

Archer Daniels Midland Company 

Attn: Pat Dennis, Mgr., Environmental Engineering Services 

4666 Faries Parkway 

Decatur, Illinois 62526 

Application No.: 99120082 

I.D. No.: 115015AAE 

Applicant's Designation: DRYER #7 

Date Received: November 6, 2002 

Subject: Wet Corn Mill Feed Dryer #7 

Date Issued: December 27, 2002 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of feed 

Dryer #7 and associated control equipment as described in the above 

referenced application. This Permit is subject to standard conditions 

attached hereto and the following special condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct the above referenced project, in that the Illinois Environmental 

Protection Agency (Illinois EPA) finds that the application fulfills all 

applicable requirements of 40 CFR 52.21. This approval is issued pursuant to 

the Clean Air Act, as amended, 42 U.S.C. 7401 et. seq., the Federal 

regulations promulgated thereunder at 40 CFR 52.21 for Prevention of 

Significant Deterioration of Air Quality (PSD), and a Delegation of Authority 

agreement between the United States Environmental Protection Agency and the 

Illinois EPA for the administration of the PSD Program. This approval 

becomes effective in accordance with the provisions of 40 CFR 124.15 and may 

be appealed in accordance with the provisions of 40 CFR 124.19. This 

approval is also based upon and subject to the following findings and the 

conditions, which follow: 

1. Archer Daniels Midland (ADM) has requested a construction permit for a 

new feed dryer (Dryer #7) in the wet corn mill (mill) at its Decatur 

manufacturing complex. The dryer produces cattle feed from ADM byproducts and the material that remains after the starch, oil and gluten 

are removed from corn. Emissions from the dryer would be controlled by 

a multi-stage control system, including cyclones, wet scrubbing, wet 

electrostatic precipitator (WESP) and a regenerative thermal oxidizer 

(RTO). Dryer #7 would allow ADM to reduce the load of the six existing 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

1-127 

feed dryers, which is expected to reduce emissions from the dryers. 

The new dryer would only facilitate a significant increase in the 

throughput of the mill if other changes were made to increase the mills 

capacity. 

2. The source is located in Decatur Township in Macon County. The area is 

designated attainment for all pollutants. 

3. The project is subject to PSD review for particulate matter (PM), 

volatile organic material (VOM), carbon monoxide (CO), and nitrogen 

oxide (NOx) because feed Dryer #7 has the potential to emit significant 

amounts of PM, VOM, CO and NOx, i.e., more than 15, 40, 100 and 40 

tons/year respectively, and ADM has not previously obtained a PSD 

permit for the six feed dryers already in the wet corn mill. The 

permit would allow annual PM, VOM, CO and NOx emissions of 26.3, 54, 132 

and 72.7 tons respectively from feed Dryer #7. (NOx figure includes 

contribution from the RTO burner). 

4. After reviewing the materials submitted by ADM, the Illinois EPA has 

determined that the project, as proposed, would (i) be in compliance 

with applicable Board emission standards and (ii) utilize Best 

Available Control Technology (BACT). 

5. The Illinois EPA has determined that the project, as proposed, would 

comply with all applicable Illinois Air Pollution Board Regulations and 

the federal Prevention of Significant Deterioration of Air Quality 

Regulations (PSD), 40 CFR 52.21. 

6. A copy of the application and a summary of the Illinois EPA=s review of 

the application and a draft of this permit were placed in a location in 

the vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing this approval subject to the following conditions 

and consistent with the specifications and data included in the application. 

Any departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization by Illinois 

EPA. 

Standard Conditions 

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply, unless 

superseded by the following special conditions. 

Best Available Control Technology

wet ESP and regenerative thermal oxidation (RTO). The control 

system shall be operated and maintained in conformance with good 

air pollution control practices. 

ii. The PM emission control system shall be designed, constructed, 

and maintained to achieve PM emission rate from Dryer #7 that is 

no more than 0.010 gr/dscf. For this purpose, PM shall be 

determined as filterable particulate matter, as measured by USEPA 

Method 5 (See Also Condition 5). 

 b. i. Dryer #7 shall be equipped, operated, and maintained with low NOx

natural gas-fired burner. The burners shall be operated and 

maintained in conformance with good air pollution control 

practices. 

ii. The burners shall be designed, constructed, and maintained to 

achieve a NOx emission rate from Dryer #7 that is no more than 

0.08 lb per million Btu heat input from fuel. 

 c. The RTO system shall be designed, constructed, and maintained to comply 

with the following limits: 

i. At least 90 percent destruction of CO by mass, (comparing the CO 

in the inlet and outlet of the system) or a CO emission rate from 

Dryer #7 that is no more than 100 PPM; and 

ii. At least 95 percent destruction of VOM by mass (comparing the VOM 

in the inlet and outlet of the system) or a VOM emission rate 

from Dryer #7 that is no more than 10 PPM. 

Condition 2 addresses Best Available Control Technology, for PM, NOx, CI and 

VOM emissions as required by Section 165 of the Clean Air Act. 

3. Limitations 

a. Emissions of PM, SO2, CO, VOM and NOx from Dryer #7 shall not 

exceed the following limits:

Permit is hereby granted to the above-designated Permittee to CONSTRUCT and 

OPERATE emission source(s) and/or air pollution control equipment consisting 

of construction of Venturi scrubbers for feed dryers 5&6 and operation of 

feed dryers 5 & 6 and their control system, as described in the above 

referenced application. This Permit is subject to standard conditions 

attached hereto and the following special condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct and operate the above referenced project, in that the Illinois 

Environmental Protection Agency (Agency) finds that the application fulfills 

all applicable requirements of 40 CFR 52.21. This approval is issued 

pursuant to the Clean Air Act, as amended, 42 U.S.C. 7401 et. seq., the 

Federal regulations promulgated thereunder at 40 CFR 52.21 for Prevention of 

Significant Deterioration of Air Quality (PSD), and a Delegation of Authority 

agreement between the United States Environmental Protection Agency and the 

Illinois EPA for the administration of the PSD Program. This approval 

becomes effective in accordance with the provisions of 40 CFR 124.15 and may 

be appealed in accordance with the provisions of 40 CFR 124.19. This 

approval is also based upon and subject to the following findings and the 

conditions, which follow: 

1a. Archer Daniels Midland (ADM) has requested a joint construction and 

operating permit for temporary operation of additional air pollution 

control equipment on feed dryers 5 and 6 in the wet corn mill (Mill) at 

its Decatur manufacturing complex. The dryers produce cattle feed from 

the material that remains after the starch, oil and gluten are removed

from corn. The additional control equipment is expected to reduce 

Particulate Matter (PM) emissions from the dryers. 

 b. The purpose of this project is to evaluate the design, operability and 

effectiveness a particular type of air pollution control equipment, 

i.e., Venturi scrubbers, to better control emissions from the various 

dryers in the wet corn mill through full scale set up and testing of a 

scrubber system on dryers 5&6. 

 c. Unless it is determined by issuance of a further PSD permit that the 

Venturi scrubbers, in conjunction with the overall control system on 

the dryers, would constitute Best Available Control Technology (BACT), 

the use of the Venturi scrubber will not be considered to be BACT after 

the temporary period of operation allowed by this permit, and the 

Permittee may be required to install other controls or remove the 

Venturi scrubber to provide BACT. 

2. The ADM complex is located in Decatur Township in Macon county. The 

area is designated attainment for all pollutants. 

3. The project is subject to PSD review for particulate matter because 

feed dryers 5&6 have the potential to emit significant amounts of 

Particulate Matter (PM), i.e., more than 15 tons/year, and ADM has not 

previously obtained a PSD permit for these dryers for the current 

levels of emissions. 

4a. After reviewing the materials submitted by ADM, the Illinois EPA has 

determined that the project, as proposed, would (i) be in compliance 

with applicable Board emission standards and (ii) as a temporary 

project utilize Best Available Control Technology (BACT). 

 b. Because this project is considered temporary, an air quality analysis 

was not required. 

5. The Illinois EPA has determined that the project, as proposed, would 

comply with applicable Illinois Air Pollution Control Regulations and 

the federal rules for Prevention of Significant Deterioration of Air 

Quality (PSD), 40 CFR 52.21. 

6. A copy of the application and the Illinois EPA’s formal review of the 

application and a draft of this permit were placed in a location in the 

vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing this approval subject to the following conditions 

and consistent with the specifications and data included in the application. 

Any departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization by Illinois 

EPA.

Decatur, Illinois 62526 

Application No.: 03080057 I.D. No.: 115015AAE 

Applicant's Designation: Date Received: July 19, 2004 

Subject: Anaerobic Wastewater Treatment System (East Plant) 

Date Issued: July 27, 2004 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of a new 

anaerobic wastewater treatment system consisting of several anaerobic 

digesters (vessels) with covers, a biological scrubber, two compressors, a 

gas dryer and a flare as described in the above-referenced application. This 

Permit is subject to standard conditions attached hereto and the following 

special condition(s): 

1.0 Unit Specific Conditions 

1.1 Unit: Anaerobic Wastewater Treatment System 

Control: Scrubber and Flare 

1.1.1 Description 

The Anaerobic Wastewater Treatment System will be located 

at ADM’s East Plant and will treat the nutrient-rich 

wastewater stream from the Soy Isolate process. The 

system will consist of several digesters vessels each with 

a cover, which will capture biogas. The biogas, which is 

mostly methane, is formed by active “fast rate” anaerobic 

digestion of solids. The digester system will be vapor 

tight insuring that all off gases are vented through the 

scrubber system. 

The scrubbed biogas will be combusted either in a flare or 

in existing fuel combustion units throughout the Decatur 

complex. The preferred disposition of the biogas is to 

the existing fuel combustion units since this will reduce 

the amount of natural gas fired in these units. ADM has 

stated that the project is being pursued because of the 

resulting savings in fuel costs at the East Plant. 

However, the system is being designed to allow biogas to

be flared to address outages of the fuel distribution 

system. This permit allows approximately 500 million 

cubic feet of biogas on an annual bases, to be fired.

1.1.3 Applicability Provisions and Applicable Regulations 

a. The “affected wastewater treatment system” for the 

purpose of these unit-specific conditions, is the 

wastewater treatment system described in Conditions 

1.1.1 and 1.1.2. 

b. No person shall cause or allow the emission of sulfur 

dioxide into the atmosphere from any process emission 

unit to exceed 2000 ppm [35 IAC 214.301]. 

1.1.4 Non-Applicability of Regulations of Concern 

a. This permit is issued based on this project not being 

a major modification pursuant to 40 CFR 52.21, 

Prevention of Significant Deterioration (PSD). This 

determination is made based on information provided 

in the application by the Permittee. The limits of 

this permit are intended to ensure that this project 

does not constitute a major modification pursuant to 

PSD. 

For this purpose, the Permittee has shown that the 

proposed Anaerobic Wastewater Treatment System is a 

separate and distinct project from the Anaerobic Lagoons 

(Construction Permit 03090034), which are being 

constructed to improve the operating efficiency of its 

existing wastewater plant. The Permittee has also shown 

that there will be a negligible increase in emissions of 

PSD pollutants attributable to the consumption of biogas 

in existing combustion units, since the combustion of 

biogas is comparable to combustion of natural gas. In 

addition, there will be at most a negligible increase in 

emissions of the fuel combustion units throughout the 

Decatur complex above baseline actual emissions as a 

result of this project.

Subject: Specialty Soybean Processes - Decatur East Plant 

Date Issued: May 25, 1999 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of new 

and modified equipment listed in Attachment A as described in the above 

referenced application. This Permit is subject to standard conditions 

attached hereto and the following special condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct the above referenced project, in that the Illinois Environmental 

Protection Agency (Agency) finds that the application fulfills all applicable 

requirements of 40 CFR 52.21. This approval is issued pursuant to the Clean 

Air Act, as amended, 42 U.S.C. 7401 et. seq., the Federal regulations 

promulgated thereunder at 40 CFR 52.21 for Prevention of Significant 

Deterioration of Air Quality (PSD), and a Delegation of Authority agreement 

between the United States Environmental Protection Agency and the Illinois 

EPA for the administration of the PSD Program. This approval becomes 

effective in accordance with the provisions of 40 CFR 124.15 and may be 

appealed in accordance with the provisions of 40 CFR 124.19. This approval 

is also based upon and subject to the following findings and conditions, 

which follow: 

1. Archer Daniels Midland (ADM) has requested a permit to increase the 

throughput of its specialty soybean process plant (Plant), by 

increasing material feed rates and hours of operation for existing 

equipment and by constructing an additional flash desolventizing unit 

and associated cooler, an additional Soy Protein Concentrate Facility 

(SPC III), and additional flake grind capacity. This plant produces a 

variety of specialty products from soybean meal after the soy oil has 

been separated and does not produce animal feed as a byproduct from oil 

extraction like most soybean plants.

2. The source is located in Decatur Township in Macon county. The area is 

currently designated as attainment for all pollutants. 

3a. The proposed project has the potential to increase Volatile Organic 

Material (VOM) emissions by as much as 3,798 tons per year assuming all 

solvent is lost as emissions, as further described in the attached 

Tables A and B. The project is therefore subject to PSD review as a 

major modification to an existing source for VOM emissions, emitting 

more than 40 tons per year. 

 b. The proposed project will not result in a significant net increase in 

particulate matter emissions, due to improvements in control of 

particulate emissions elsewhere at this grain processing complex, as 

explained in Table C. The project is therefore not subject to PSD 

review for particulate matter. 

4a. After reviewing the materials submitted by ADM, Illinois EPA has 

determined that the project will (i) be in compliance with applicable 

Board emission standards and (ii) utilize Best Available Control 

Technology (BACT) on emissions of VOM. 

 b. Notwithstanding the Illinois EPA's determination of BACT, the plant 

will be subject to Maximum Achievable Control Technology (MACT) for 

hexane when USEPA adopts standards pursuant to Section 112(d) for 

existing vegetable oil production facilities. 

5. The Illinois EPA has determined that the proposed project complies with 

all applicable Illinois Air Pollution Board Regulations and the federal 

Prevention of Significant Deterioration of Air Quality Regulations 

(PSD), 40 CFR 52.21. 

6. A copy of the application and the Illinois EPA’s formal review of the 

application and a draft of this permit were placed in a location in the 

vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing approval to construct the proposed project 

subject to the following conditions and consistent with the specifications 

and data included in the application. Any departure from the conditions of 

this approval or terms expressed in the application would need to receive 

prior written authorization by Illinois EPA. 

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply to this 

project, unless superseded by the following special conditions. 

2a. VOM consumption, i.e., hexane consumption, at the modified Decatur East 

Soybean Specialty Plant shall not exceed 10.4 pounds per ton of 

soybeans processed. Compliance with this limit shall be determined 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-182 

from a 180 day rolling average of operating records on a daily basis, 

following the initial shakedown period. 

(Note: Consumption of VOM by the Soybean Plant is greater than 

emissions of VOM to the extent that VOM is retained in product and 

waste, rather than lost to the atmosphere. The application shows 

minimum retention of 0.4 pound VOM per ton of soybeans processed, so 

that the above limit is equivalent to VOM emissions of no more than 

10.0 pound per ton.) 

 b. The VOM control system on the main vent for the Soybean Specialty 

Extraction Facility shall consist of a condenser and mineral oil 

scrubber operated in conformance with good air pollution control 

practices, including: 

i. The control system shall be operated to control VOM emissions 

from the soybean oil extractor, desolventizing systems, vegetable 

oil stripping system, wastewater stripping system and mineral oil 

stripping system at all times when the affected process equipment 

is in operation. 

ii. The control system’s packed-bed scrubber shall be operated with 

“lean” mineral oil scrubbant from which hexane has been 

effectively removed in the mineral oil stripper by heating the 

mineral oil to at least 200F. 

iii. The control system shall be operated to comply with the following 

requirements except during equipment startup and shutdown: 

A. A maximum gas outlet temperature for the condenser (inlet 

temperature to the scrubber) of 95F or no more than 10F 

above the ambient temperature, whichever is greater; 

B. A minimum mineral oil flow rate of 16 gallons per minute 

(This is equivalent to a design minimum flow rate of 1 

gallon per 10 cubic feet); 

C. A maximum mineral oil inlet temperature for the scrubber 

of 95F or no more than 10F above the ambient 

temperature, whichever is greater; 

D. A scrubber pressure drop within the range established for 

normal operation; and 

E. A maximum hexane concentration in the main vent exhaust of 

30% of the Lower Explosion Limit (LEL). The LEL for 

hexane in air is 12,000 ppm. 30% of the LEL is equivalent 

to VOM emissions of 4.6 lb/hour, at a nominal exhaust rate 

of 100 cfm.

iv. The control system shall be operated to reasonably minimize 

emissions during equipment startup and shutdown, including 

thorough purging of process equipment to the operating control 

system prior to opening the process equipment for routine 

maintenance or repair. 

3a. VOM consumption, i.e., ethanol consumption, at the modified Decatur 

East Protein Concentrate Facility shall not exceed 24.0 pounds per ton 

of flake processed. Compliance with this limit shall be determined 

from a 180 day rolling average of operating records on a daily basis, 

following the initial shakedown period. 

(Note: Consumption of VOM by the Protein Concentrate Facility is 

greater than emissions of VOM to the extent that VOM is retained, both 

physically and chemically, in product and waste rather than lost to the 

atmosphere. The application shows minimum chemical retention by 

hydrogen bonding of 11.2 pound VOM per ton of flake processed, so that 

the above limit is equivalent to VOM emissions of no more than 12.8 

pound per ton. In addition, an estimated 3.0 pound per ton is retained 

in "wastes" that are used elsewhere at the complex, e.g., the ethanol 

plant, further reducing emissions to no more than 9.8 pounds per ton.) 

 b. The VOM control systems on the main vents for the Protein Concentrate 

Facility shall consist of a condenser and packed-bed water scrubber 

operated in conformance with good air pollution control practice, 

including: 

i. The control systems shall be operated to control VOM emissions 

from the soy soluble extractors, desolventizing systems and soy 

soluble stripping system at all times when the affected process 

equipment is in operation. 

ii. The control systems’ packed-bed scrubber shall be operated with 

once-through scrubbant if the scrubbant is not processed to 

effectively strip ethanol and cooled prior to reuse. 

iii. The control systems shall be operated to comply with the 

following requirements except during startup and shutdown of 

affected equipment: 

A. A maximum gas outlet temperature for the condenser (inlet 

temperature to the scrubber) within the range established 

for normal operation; 

B. A minimum water flow rate of 8 gallons per minute (This is 

equivalent to a design minimum flow rate of 1 gallon per 

20 cubic feet); 

C. A scrubber pressure drop within the range established for 

normal operation; and 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

1-184 

D. A maximum gas outlet temperature for the scrubber (exhaust 

to the atmosphere) of 105F or 10F greater than the 

ambient temperature, whichever is higher. 

iv. The control systems shall be operated to reasonably minimize 

emissions during startup and shutdown of affected equipment 

including thorough purging of affected process equipment to the 

operating control system prior to opening the process equipment 

for maintenance or repair. 

4. The Permittee shall implement a Leak Detection and Repair Program for 

components in VOM service that is consistent with the requirements, if 

any, in the regulations for vegetable oil extraction plants adopted by 

USEPA pursuant to Section 112 (d) of the Clean Air Act. Until such 

regulations are adopted by USEPA and are applicable to this plant, the 

Permittee shall implement an interim program that shall include the 

following elements as a minimum: 

a. Scope: The program covers all components that are in VOM service 

in the process operations, other than components in vacuum 

service and components equipped with a closed vent system ducted 

to a VOM control system where the term component includes valves 

pumps and agitators (shaft seals), flanges, other connectors 

(inspection ports, manways, sight glasses, etc.), closed vent 

systems, and pressure relief devices. 

b. Definitions: 

Leak: 

An instrument reading of 10,000 ppm or greater for components 

other than pressure relief devices, an instrument reading of 500 

ppm or greater for pressure relief devices, or observation of 

leaking material from a component as detected by sight, smell or 

sound is considered a leak. 

Leaks That May Be Readily Identified By Visual Inspection: 

Leaks from a component shall be considered to be readily 

identified by visual inspection if (1) the component is in liquid 

service, (2) the vapor pressure of the VOM is less than 0.1 psia 

at 20C or the VOM is accompanied by at least 25% water, by 

weight, and (3) a walk-through inspection for leaks in the area 

in which the component is located is conducted by the Permittee 

at least weekly. 

c. Inspections are conducted on at least the following basis for 

components for which leaks may not be readily identified by 

visual inspection, using applicable instrument and source survey

calibration is not required on a daily basis if the instrument is 

self-calibrating and is serviced in accordance with the 

manufacturer's specifications) or the screening procedures in 

Method 21. Inspections are as follows: 

Quarterly for affected components other than flanges, other 

connectors, and closed vent systems, except for valves as USEPA 

skip-check criteria and alternative practices established in 40 

CFR 60.483-2 (NSPS for SOCMI Leaks) are satisfied; 

Annually for closed vent systems; 

Within a week for a pressure relief device after it experiences a 

pressure release; 

Within a week for the flanges and other connectors in a 

particular area, system or feature after such components are 

involved in repair, maintenance, alteration or other activity 

that has the potential to result in a leak from flanges or other 

connectors, including resealing of a manway after entry to a 

vessel, if absence of leaking components was not verified as a 

final step in such activity by use of a soap solution or other 

comparable technique; and 

Within a week after repair of a component for which a leak was 

detected and could not be readily repaired within one hour. 

d. Repairs: Repairs are made as soon as practicable but not later 

than 30 days after identification or detection of a leak if 

repair is feasible without a process unit shutdown or not later 

than the end of the next process unit shutdown if one is 

necessary to accomplish the repair. 

e. Tagging: A leaking component is “tagged” if it cannot be readily 

repaired within one hour of detection of a leak, which tag 

includes the date the leak was detected and the date the leak was 

repaired and which tag is only removed after the repaired 

component is inspected. 

f. Records: Records are maintained that: 

Facilitate correct and consistent identification of the 

components that are covered by the program. 

Verify performance of required inspections, including date, 

personnel, proper implementation of inspection methods, purpose 

or scope of inspection, covered components and results.

identification of the component and the nature of the leak, and 

verify prompt repair of the leak, including the date the repair 

is completed and detailed explanation of the required actions for 

a leak repair that could not be completed within 10 days. 

Compile the results of the program, including fulfillment of 

skip-check criteria for conventional valves when relied upon. 

Identify each deviation from required practices, with appropriate 

identification, description and explanation. 

g. Revisions: The minimum provisions for tagging and recordkeeping, 

as specified above, may be revised by the Illinois EPA in future 

operating permits for the plant to the extent that the Permittee 

demonstrates that effective detection and repair of leaking 

components is still reasonably assured by the revised provisions.

emission source(s) and/or air pollution control equipment consisting of 

expansion of the West oil refinery, including new and modified boilers and 

new and modified silos and day bins as described in the above-referenced 

application. This Permit is subject to standard conditions attached hereto 

and the following special condition(s): 

1. General Conditions 

a. This permit authorizes the expansion of the Decatur West 

Refinery, including installation of new units and modifications 

of existing units. 

b. This permit does not authorize modifications elsewhere at the 

source. 

2. Emissions of volatile organic material (VOM) from the processing and 

handling of vegetable oil at the refinery shall not exceed 83.0 

ton/year. This represents an increase in VOM emissions of 30.5 

ton/year compared to average annual emissions of VOM in 2002 and 2003, 

as presented by the Permittee in the application. Note: Certain VOM 

emissions from raw oil produced at the Decatur extraction plant are 

also accounted for as part of the extraction process at the source. 

3. This permit is issued based on the expansion of the refinery not 

constituting a major modification subject to the federal Prevention of 

Significant Deterioration rules (PSD) 40 CFR 52.21, because the total 

emissions of the refinery are less than the PSD significant emission 

thresholds.

b. This permit is issued based on the modification not being subject to 

PSD requirements for PM/PM10 because the net increase is less than 15 

tons/year. Previous past actual PM emissions were 30.72 tons/year and 

new total is 39.35 tons/year for an increase of 8.63 tons. 

5a. The emission units in the west germ processing plant shall be operated 

to comply with the particulate matter emission standard of 35 IAC 

212.321. 

 b. The plant shall be operated to comply with the applicable standard for 

hazardous air pollutants (HAP) in 40 CFR 63 Subpart GGGG, National 

Emission Standards for Hazardous Air Pollutants: Solvent Extraction 

for Vegetable Oil Production. This standard limits loss of organic 

solvent from the plant to 0.4 gallon/ton of corn germ, on a 12-month 

rolling average, beginning April 2004 [40 CFR 63.2840]. 

 c. The plant shall be operated to comply with applicable requirements 

under the Consent Decree entered into by the Permittee with the United 

States and State of Illinois, in the United State District Court for 

the Central District of Illinois, United States v. Archer Daniels 

Midland Company, Civil Action No. 03-2006. In particular, this decree 

sets an interim limit of 0.31 gallon/ton for organic solvent loss from 

the plant (Paragraph 47). 

6a. This permit is issued based on the west germ processing plant being 

designated as a Clean Unit for emissions of VOM. [40 CFR 52.21(x)] The 

change in VOM emission with this project, i.e., the addition of another 

expeller, is not addressed because of Clean Unit Status. In this regard, 

a PSD permit was issued for the plant in the last 10 years (Construction 

Permit 95050124), which limits VOM emissions to no more than 0.52 gallons 

per ton of corn germ crush. No changes are being made to VOM emission 

limits or work practices that were established as BACT. 

 b. This permit is issued based on the design of the west germ processing 

plant as related to VOM emissions, being consistent with the design 

addressed by Permit 95050124. 

 c. This permit does not revise or relax any limitations or requirements 

related to VOM or hexane contained in Construction Permit 95050124, 

e.g., annual hexane consumption continues to be limited to 1709.7 tons 

per any 12-month period, pursuant to Construction Permit 95050124, 

Condition 4. 

7a. Within 180 days after initial start up of the new corn germ expeller, 

the Permittee shall at its own expense, conduct tests for PM emissions 

and opacity from the corn germ expellers in accordance with the 

applicable test methods and procedures as identified below.

Application No.: 02050010 I.D. No.: 115015AAE 

Applicant's Designation: EXTRACTOR Date Received: April 15, 2003 

Subject: DTDC/Distillation Modifications, Replacement Extractor 

Date Issued: June 2, 2003 Operating Permit Expiration

Date: July 18, 2007 

Location: 3883 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT and 

OPERATE emission source(s) and/or air pollution control equipment consisting 

of a replacement of the existing deep-bed extractor with a shallow-bed 

extractor, alterations to the existing desolventizer-toaster-dryer-cooler 

(DTDC) including the installation of additional desolventizing decks, and 

replacement of several condensers in the solvent recovery system as described 

in the above-referenced application. This Permit is subject to standard 

conditions attached hereto and the following special condition(s): 

1.0 Unit Specific Conditions 

1.1 Unit: Vegetable Oil Production Process 

Control: Mineral Oil Scrubber, Dust Collectors 

1.1.1 Description 

The Permittee is making changes to its West soybean plant, 

in which it processes soybeans to recover soybean oil and 

produce soybean meal for animal consumption. The oil 

extraction process consists of “washing” soybean flakes 

with solvent (hexane). The source is replacing the 

existing deep-bed extractor with a newer shallow-bed 

extractor. 

The soybean flakes leaving the extractor, which have 

adsorbed some solvent, are desolventized in the 

desolventizer toaster where steam is used to drive off the 

solvent. The toasted flakes then pass to a dryer, where 

excess moisture is removed by heat and then to a cooler 

where ambient air is used to reduce the temperature of the 

flakes. As part of this application, several 

desolventizing decks will be replaced and added in the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-248 

existing desolventizer-toaster-dryer-cooler (DTDC) to 

improve the effectiveness of solvent removal so that less 

solvent is emitted from the dryer and cooler. Solvent 

vapors are recovered from the extractor and desolventizertoaster by a number of condensers and a mineral oil 

scrubber. The recovered solvent is processed for reuse. 

Several condensers will be replaced. 

The particulate emissions from the dryer and cooler are 

captured and exhausted to a dust collector, which will 

recover product and reduce emissions. 

The amount of hexane emitted is determined by a material 

balance calculating the amount of hexane used from the 

amount received and changes in the amount stored.

I.D. Number: 115015AAE 

Application No.: 96030038 

1-249 

existing source for purposes of 40 CFR 63, 

Subpart GGGG. 

c. i. The affected plant is subject to 35 IAC 

212.321(a), which provides that the emission 

of particulate matter into the atmosphere in 

any one hour period from any new process 

emission unit, either alone or in combination 

with the emission of particulate matter from 

all other similar process emission units for 

which construction or modification commenced 

on or after April 14, 1972, at a source or 

premises, shall not exceed the allowable 

emission rates specified in subsection (c) of 

35 IAC 212.321 [35 IAC 212.321(a)]. 

ii. A. The Permittee shall not cause or allow 

the emission of smoke or other 

particulate matter, with an opacity 

greater than 30 percent, into the 

atmosphere from the affected plant except 

as provided below [35 IAC 212.123(a)]. 

B. The emission of smoke or other 

particulate matter from the affected 

plant may have an opacity greater than 30 

percent but not greater than 60 percent 

for a period or periods aggregating 8 

minutes in any 60 minute period provided 

that such opaque emissions permitted 

during any 60 minute period shall occur 

from only one such emission unit located 

within a 305 m (1000 ft) radius from the 

center point of any other such emission 

unit owned or operated by the Permittee, 

and provided further that such opaque 

emissions permitted from each such 

emission unit shall be limited to 3 times 

in any 24 hour period [35 IAC 

212.123(b)]. 

1.1.4 Non-Applicability of Regulations of Concern 

a. The source has addressed the applicability and 

compliance of 40 CFR 52.21, Prevention of Significant 

Deterioration (PSD). The provisions in this permit 

are intended to ensure that the modification 

addressed in this construction permit does not 

constitute a major modification pursuant to these 

rules. In particular: 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-250 

i. With respect to emissions of volatile organic 

material (VOM), the modifications to the 

affected plant are intended to reduce the 

solvent loss rate, to facilitate compliance 

with 40 CFR 63 Subpart GGGG and future usage 

of solvent is limited to a level that is below 

historical levels in 2000 and 2001 (1017 tons 

compared to 1033 tons) to reflect this 

reduction in VOM emissions (Refer to Condition 

1.1.6(c)(i)). 

ii. With respect to emissions of particulate 

matter, the operation and emissions of the 

affected plant are being limited to ensure 

that the increases are less than significant, 

e.g., an increase of at most 12.7 tons/year of 

PM10 compared to the 15 tons/year significant 

emission threshold for PM10. In the event that 

emission testing required by Condition 1.1.7 

identifies significant discrepancies between 

emissions as measured and emissions as 

estimated by engineering calculations, the 

Permittee shall expeditiously apply for 

appropriate revisions to this permit to ensure 

that it effectively constrains the affected 

plant so that it is not a major modification 

or shall undergo PSD permitting for 

particulate matter. 

b. This permit is issued based on the affected plant not 

being subject to 35 IAC 215 Subpart K, Use of Organic 

Material, because hexane is not a photochemically 

reactive material, as defined in 35 IAC 211.4690. 

1.1.5 Operational Limits 

a. No later than April 12, 2004, the affected plant

Subject: Bio Products Pilot Fermentation System 

Date Issued: May 6, 2005 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of 

modifying the pilot fermentation system, as described in the above-referenced 

application. This Permit is subject to standard conditions attached hereto 

and the following special condition(s): 

1a. This permit allows modifying the pilot fermentation system, by addition 

of a scrubber, to allow evaluation of production of biopolymers. 

 b. This permit allows use of the pilot fermentation system for research 

and development of product lines other than biopolymers. 

 c. i. This permit also authorizes operation of an existing production 

propagator and seed fermentor as part of the pilot system, for 

which purpose these units shall also be piped to and vented 

through the scrubber. 

ii. This permit also authorizes use of the propagator and seed 

fermentor that were originally part of the pilot system for the 

purpose of production as well as pilot work from the production 

operations, as the pilot equipment will take the place of 

production equipment. For this purpose, this permit is issued 

based on no increase in emissions. 

2. This permit is issued based on the pilot fermentation system not being 

subject to 40 CFR Part 60, Subpart VV, Performance for Equipment Leaks 

of VOC in the Synthetic Organic Chemicals Manufacturing Industry 

because the materials being produced are not included in 40 CFR 60.489. 

3a. At all times, the Permittee shall maintain and operate the modified 

pilot fermentation system, including the scrubber, in a manner 
CAAPP PERMIT

consistent with good air pollution control practice for minimizing 

emissions. 

b. i. Except during loading or unloading of a vessel, the exhaust flow 

rate of the pilot fermentation system shall not exceed 3,000 

scfm. 

ii. The scrubber shall be run at all times the pilot fermentation 

system is operating, for production of biopolymers or other new 

fermentation products. 

 c. The wastewater from the scrubber shall be managed so as to minimize 

emissions of recovered or entrained pollutants to the atmosphere, by 

either reusing the material as a process feed or sending it directly to 

the wastewater treatment plant. 

4a. i. Emissions of volatile organic materials (VOM) from the modified 

pilot fermentation system shall not exceed the following limits: 

Pollutant Lbs/Hr Tons/Yr 

VOM 6.0 26.8 

ii. This permit is issued based on negligible emissions of 

particulate matter from the modified pilot fermentation system. 

For this purpose, emissions shall not exceed nominal emission 

rates of 0.1 lb/hour and 0.44 tons/year. 

 b. The pilot fermentation system is not a major process unit subject to 

Section 112(g) of the Clean Air Act, Hazardous Air Pollutants (HAPs) 

because emissions of HAPs are less than 10 tons/year for a single HAP 

and less than 25 tons/year for all combined HAPs 

Note: These limits establish the potential emission of the modified 

fermentation system, as set forth by the Permittee in the application. 

The actual emissions will likely be far below these limits based on 

bench scale testing conducted by the Permittee. However the Permittee 

has requested these higher limits since the fermentation system is 

being used for research and development of a new product and reliable 

data confirming lower levels of emissions is not yet available. 

5. The following methods and procedures shall be used for testing of 

emissions upon request of the Illinois EPA, unless another method is 

approved by the Illinois EPA: Refer to 40 CFR 60 Appendix A, and 40

Date Received: July 9, 2001 

Subject: Vitamin C Production 

Date Issued: July 20, 2001 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT emission 

source(s) and/or air pollution control equipment consisting of a Vitamin C 

Production Plant, including Vitamin C synthesis, product drying, product 

handling, solvent recovery, and raw material silos as described in the above 

referenced application. This Permit is subject to standard conditions attached 

hereto and the following special condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct the above referenced project, in that the Illinois Environmental 

Protection Agency (Agency) finds that the application fulfills all applicable 

requirements of 40 CFR 52.21. This approval is issued pursuant to the Clean 

Air Act, as amended, 42 U.S.C. 7401 et. seq., the Federal regulations 

promulgated thereunder at 40 CFR 52.21 for Prevention of Significant 

Deterioration of Air Quality (PSD), and a Delegation of Authority agreement 

between the United States Environmental Protection Agency and the Illinois 

EPA for the administration of the PSD Program. This approval becomes 

effective in accordance with the provisions of 40 CFR 124.15 and may be 

appealed in accordance with the provisions of 40 CFR 124.19. This approval 

is also based upon and subject to the following findings and the conditions 

which follow: 

1. Archer Daniels Midland (ADM) requested a revised construction permit 

for the Vitamin C plant (Plant) at its Decatur manufacturing complex. 

The revised permit would allow for greater volatile organic material 

(VOM) emissions from the plant. VOM emissions occur from the solvent 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

1-301 

needed for final processing of intermediate Vitamin C feedstock, which 

has been produced through a series of water-borne processes. The 

emissions of solvent are controlled by a scrubber, which recovers 

solvent for reuse, from the point at which solvent is first introduced 

into the process through the final dryer for Vitamin C product. 

2. The source is located in Decatur Township in Macon county. The area is 

designated attainment for all pollutants. 

3. The permit allows annual VOM emissions of 400 tons from the plant. The 

plant would therefore be subject to PSD as a major modification to an 

existing source for VOM emissions. 

4. The permit allows annual emissions of hazardous air pollutants (HAPs) 

that are more than 10 tons of a single HAP, i.e., methanol. 

Accordingly, the plant is subject to USEPA’s National Emission 

Standards for Pharmaceutical Production, 40 CFR Part 63, Subpart A and 

GGG, as an existing source. However, in the event that the delisting 

process currently under way by USEPA for methanol declassifies it, this 

standard may no longer apply to the Vitamin C plant. 

5. After reviewing the materials submitted by ADM, Illinois EPA determined 

that the plant, as proposed, is designed to: 

a. Comply with applicable Pollution Control Board emission 

standards, 

b. Comply with federal emission standards for hazardous air 

pollutants from pharmaceutical production, and 

c. Utilize Best Available Control Technology (BACT) on emissions of 

VOM. 

6. The Illinois EPA determined that the application complies with all 

applicable state and federal air pollution regulations, including the 

federal rules for Prevention of Significant Deterioration of Air 

Quality Regulations (PSD), 40 CFR 52.21. 

7. A copy of the application and the Illinois EPA’s formal review of the 

application and a draft of this permit were placed in a location in the 

vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing this approval subject to the following conditions 

and consistent with the specifications and data included in the application. 

Any departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization by Illinois 

EPA.

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply, unless 

superseded by the following special conditions. 

2a. All process vents in the plant discharging VOM, including any vacuum 

systems and VOM solvent tanks, shall be enclosed and ducted through a 

closed vent system to a VOM emission control system. 

 b. The VOM emission control systems shall be designed and constructed to 

achieve at least 98% control of VOM comparing the amount of VOM 

introduced into the processes and the emissions to the atmosphere. 

These control systems shall be operated and maintained in conformance 

with good air pollution practice. 

3a. The Permittee shall implement the following practices for components 

and materials to minimize VOM emission losses from leaking components 

unless and until an equivalent practice is approved by the Illinois 

EPA: 

i. Open-ended valves shall only be present as needed for routine 

sampling of a process. 

 b. The Permittee shall implement a Leak Detection and Repair Program for 

components in VOM service (i.e., containing process fluids that are at 

least 10 percent VOM by weight) in the process units of the plant. 

This program shall include the following elements as a minimum, except 

for those components for which the Permittee must implement and comply 

with a Leak Detection and Repair Program pursuant to 40 CFR 63.1255 

(See Condition 4). 

i. Scope: The program covers components that are in VOM service in 

the process operations, other than components in vacuum service 

and components equipped with a closed vent system ducted to a VOM 

control system, where the term component includes valves, pumps 

and agitators (shaft seals), flanges, other connectors 

(inspection ports, manways, sight glasses, etc.), closed vent 

systems, and pressure relief devices. 

ii. Definitions: 

Leak: 

An instrument reading of 10,000 ppm or greater for components 

other than pressure relief devices, an instrument reading of 500 

ppm or greater for pressure relief devices, or observation of 

leaking material from a component as detected by sight, smell, or 

sound is considered a leak. 

Low-Leak Design Pump: 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-303 

A pump fitted with double mechanical pressurized seals, equipped 

with a permanent gauge for seal pressure* and that is operated 

and maintained consistent with good practice, or other similar 

pump design as approved by the Illinois EPA that both minimizes 

leaks and directly reveals the presence of a leak. 

* This pressure gauge may be installed on the individual 

pump or installed as part of a central seal fluid system 

if each pump is equipped with a device to indicate flow of 

seal fluid. 

iii. Monitoring: Monitoring is conducted on at least the following 

basis for components using applicable instrument and source 

survey procedures specified by USEPA Method 21 (except that daily 

manual calibration is not required if the instrument is selfcalibrating) or the screening procedures in such methods are 

satisfied. Inspections are as follows: 

Quarterly for valves (except for conventional valves as USEPA 

skip-check criteria and alternative practices established in 40 

CFR 60.483-2 (NSPS for SOCMI Leaks) are satisfied) and pumps 

(except pumps that are of low leak design); 

Annually for closed vent systems; 

Within a week for a pressure relief device after it experiences a 

pressure release; 

Within a week for the flanges and other connectors in a 

particular area, system or feature after such components are 

involved in repair, maintenance, alteration or other activity 

that has the potential to result in a leak from flanges or other 

connectors, including resealing of a manway after entry to a 

vessel, if absence of leaking components was not verified as a 

final step in such activity by use of a soap solution or other 

comparable technique; and 

Within a week after repair of a component for which a leak was 

detected and could not be readily repaired within one hour. 

iv. Visual Inspection: Pumps and agitator shafts shall be inspected 

by visual inspection on a weekly basis for indications of liquids 

dripping from the seal. If there are indications of liquids 

dripping from a seal, a leak is detected. 

v. Repairs: Repairs are made as soon as practicable but not later 

than the following: 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-304 

For a component other than a pump or valve, if a process unit 

shutdown is necessary to accomplish the repair, not later than 

the end of the next process unit shutdown. 

For a pump or valve, if a process unit shutdown is necessary to 

accomplish the repair, not later than the end of the next process 

unit shutdown or 6 months, whichever occurs first, except that 

further delay of repair of a valve is allowed (beyond the next 

process unit shutdown) if reasonable supplies of repair parts or 

replacement valves are maintained but these supplies are 

depleted, in which case repair of a valve shall be accomplished 

not later than 6 months after the first process unit shutdown or 

1 year after detection of the leak, whichever occurs first. 

vi. Tagging: A leaking component is "tagged" if it cannot be readily 

repaired within one hour of detection of a leak, which tag 

includes the date the leak was detected and the date the leak was 

repaired and which tag is only removed after the repaired 

component is inspected. 

vii. Records: Records are maintained that: 

Facilitate correct and consistent identification of the 

components that are covered by the program, including at a 

minimum having available an up to date process diagrams for the 

plant. 

Verify performance of required inspections, including date, 

personnel, proper implementation of inspection methods, purpose 

or scope of inspection, covered components and results (leak/noleak status of the covered equipment). 

Document each component leak that is identified, including 

identification of the component and the nature of the leak, and 

verify prompt repair of the leak, including the date the repair 

is completed and detailed explanation of the required actions for 

a leak repair that could not be completed within 30 days, further 

explanation if a repair could not be completed until process unit 

shutdown or thereafter, and the date required inspection of the 

component was performed following repair. 

Compile the results of the program, including fulfillment of 

skip-check criteria for conventional valves when relied upon. 

Identify each deviation from required practices, with appropriate 

identification, description and explanation. 

Document proper operation, maintenance, and repair of low-leak 

design pumps.

viii. Revisions: The minimum provisions for tagging and recordkeeping, 

as specified above, may be revised by the Illinois EPA in future 

operating permits for the plant to the extent that the Permittee 

demonstrates that effective detection and repair of leaking 

components is still reasonably assured by the revised provisions. 

Conditions 2 and 3 address Best Available Control Technology as required by 

Section 165 of the Clean Air Act. 

4a. i. The VOM control system shall be maintained and operated to comply 

with the applicable control efficiency requirements of the 

National Emissions Standard for Pharmaceutical Production, 

Standards: Process Vents, and Standards: Storage Tanks for 

emissions of HAP [40 CFR 63.1253(b) and 63.1254(a)]. 

ii. The Permittee shall not rely on the emission averaging provisions 

of these standards without first having submitted a timely and 

complete implementation plan to the Illinois EPA. 

 b. Components in HAP service shall be subject to a Leak Detection and 

Repair Program and other applicable requirements of National Emission

purpose, methanol shall be considered a water soluble HAP [40 CFR 63, 

Subpart GGG, Table 3]. 

 d. If USEPA removes methanol from the list of HAPs, the above Condition 

4(a), (b), and (c) and Condition 12(e) shall no longer apply as 

follows: 

i. These conditions shall no longer apply if 40 CFR Part 63, Subpart 

GGG is not otherwise applicable, as confirmed by the Permittee in 

writing to the Illinois EPA. 

ii. This provisions shall take effect 30 days after written notice 

from the Permittee, which notice shall explain any changes in 

applicable requirements for the plan. 

5a. Emissions of VOM by the plant shall not exceed 400 tons per year.

Findings 

1a. Archer Daniels Midland Co. (ADM) operates boilers to supply steam and 

generate electricity for its grain processing operations. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-352 

 b. ADM has requested a permit to construct two circulating fluidized bed 

(CFB) boilers (#9 and #10), each with limestone injection, a baghouse, 

and a selective non-catalytic NOx reduction system; one gas fired boiler 

(#11) with low NOx burner and flue gas recirculation; and associated 

changes to coal and limestone handling and storage systems, including a 

new limestone storage silo and limestone unloading rail dump both with 

baghouses. The nominal capacity of the boilers is 1,500 MBtu/hour for 

each CFB boiler and 350 MBtu/hour for the gas fired boiler. 

2. The plant is located in Decatur Township in Macon County. The area is 

currently designated attainment for all air quality standards. The 

county has a class II designation for Prevention of Significant 

Deterioration (PSD) permit review. 

3. The plant is a major source under PSD rules. The proposed project will 

increase potential annual emissions by 9,200 tons/year of sulfur 

dioxide (SO2), 1,654 tons/yr of nitrogen oxides (NOx), 334 tons/yr of 

particulate matter, 1,375 tons/yr of carbon monoxide (CO), 482 tons/yr 

of volatile organic compounds (VOC), 5 tons/yr of lead, and 16 tons/yr 

of fluorides. The project is therefore subject to PSD review as a 

major modification for the above contaminants. 

4. The new boilers and associated new equipment must be operated so that 

emissions are in compliance with (i) all applicable Pollution Control 

Board emission standards, (ii) federal New Source performance standards 

for emissions of SO2, NOx and PM, and (iii) Best Available Control 

Technology (BACT) for emissions of SO2, NOx, PM, CO, VOC, lead, and 

fluorides as set in conditions of this permit. The application 

submitted by ADM, as reviewed by the Illinois EPA shows that the 

project will comply with these requirements. Emissions of lead and 

fluorides are addressed by limits on other contaminants, i.e., PM and 

SO2. 

5. The air quality analysis submitted by ADM and reviewed by the Illinois 

EPA shows that this project will not cause a violation of the ambient 

air quality standards. The air quality analysis also shows compliance 

with the allowable increment for PM, SO2, and NOx. 

6. The Illinois EPA has determined that the application for the proposed 

project complies with all applicable Pollution Control Board 

Regulations the federal New Source Performance Standards 40 CFR 60, 

Subpart Db, and the federal Prevention of Significant Deterioration of 

Air Quality Regulations (PSD), 40 CFR 52.21. 

7. A copy of the application, and the Illinois EPA's review of the 

application and a draft of this permit were placed in a location in the 

Decatur City Clerk's Office, Decatur Civic Center, and the public has 

been given notice and opportunity to examine this material and to 

submit comments and to request and participate in a public hearing on 

this matter.

The Illinois EPA is issuing approval subject to the following conditions and 

consistent with the specifications and data included in the application. Any 

departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization of the Illinois 

EPA. 

Conditions 

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply to this 

project, unless superseded by the following conditions. 

2a. The emissions from each CFB boiler (#9 and #10) shall not exceed the 

following limits: 

i. PM - 0.025 lb/MBtu; 

ii. SO2 – 0.70 lb/MBtu, and 

8% of the coal’s potential SO2 emission rate, i.e., at least 92% 

reduction. (This reduction based limit is equivalent to an 

emission rate of 0.70 lb SO2/mmBtu when firing a coal supply 

containing 4.4 lb sulfur (S)/MBtu. It requires a lower emission 

rate if the coal supply contains less sulfur, e.g., 0.40 lb 

SO2/mmBtu for a coal supply containing 2.5 lb S/MBtu.) 

These limits shall apply on a 30 day rolling average using the 

compliance procedures of the NSPS, 40 CFR Part 60, Subpart Db, 

except that emissions during startup and shutdown, as addressed 

below, shall be excluded and not be considered for purposes of 

the reduction based limit. 

iii. NOx – 0.120 lb/MBtu, when firing a coal supply containing more 

than 2.5 lb S/ MBtu or 0.090 lb/MBtu when firing a coal supply 

containing 2.5 lb S/MBtu or less or such lower limit as set by 

the Illinois EPA following the Permittee’s evaluation of NOx

emissions and the SNCR system, as provided below. 

This NOx limit shall apply on a 30 day rolling average using the 

compliance procedures of the NSPS, 40 CFR Part 60, Subpart Db 

from 17(b). 

For this purpose, the determination of sulfur content shall be 

made based on the typical sulfur content of the coal on a time 

period that is at least monthly. 

iv. CO - 0.10 lb/MBtu. 

v. VOC - 0.032 lb/MBtu. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-354 

 b. The Permittee shall use reasonable practices to minimize emissions of 

SO2 during startup and shutdown of a boiler, including conducting 

startup and shutdown of boilers in accordance with written procedures 

maintained on site that are specifically developed to minimize SO2

emissions from both "cold" and "hot" startups and shutdowns, that as a 

minimum include the following measures: 

i. Review of the operational condition of a boiler prior to 

initiating startup of the boiler. 

ii. Use of natural gas during startup to heat the boiler prior to 

initiating firing of coal or other solid fuel. 

iii. Review of the operating parameters of the boiler during each 

startup as necessary to make appropriate adjustments to the 

startup to minimize emissions of SO2 and other pollutants. 

 c. The Permittee shall evaluate NOx emissions from the CFB boilers to 

determine whether a lower NOx emission limit (as low as 0.100 and 0.070 

lb/MBtu, respectively, depending upon whether sulfur content of the 

coal more or less than 2.5 lb/MBtu) may be reliably achieved while 

complying with other emission limits without significant risk to 

equipment or personnel, significant increase in ammonia emissions, and 

unreasonable increase in maintenance and repair needed for the boilers. 

3a. The only fuel fired in the gas fired boiler (#11) shall be gaseous 

fuel. For this purpose, gaseous fuel is defined as "commercial" 

natural gas (see 40 CFR 60.4(b) and gaseous process emission streams 

fired for purposes of energy recovery, odor control, or safety. 

 b. The emissions from the gas fired boiler (#11) shall not exceed the 

following limits: 

i. NOx - 0.05 lb/MBtu. 

This limit shall apply on a 30 day rolling average using the 

compliance procedures of the NSPS, 40 CFR Part 60, Subpart Db. 

ii. CO - 0.04 lb/MBtu. 

iii. VOC - 0.014 lb/MBtu. 

4a. Emissions of particulate matter from the new limestone unloading rail 

dump and limestone silo #4 shall be controlled with bag filters 

designed to emit no more than 0.01 grains/dry standard cubic foot. 

 b. i. Emissions of particulate matter from coal handling and conveying 

shall be controlled with enclosures and aspiration to bag 

filters.

ii. Emissions from coal storage shall be controlled by an enclosure. 

Conditions 2, 3 and 4 represents the application of the Best Available 

Control Technology as required by Section 165 of the Clean Air Act. Limits 

are to be met on an hourly basis, unless otherwise specified. Compliance 

shall be demonstrated by emission testing, monitoring and recordkeeping in 

accordance with Conditions 8, 9, 10, 11, 12 16 and 17. 

5a. The two CFB boilers (#9 and #10) and the gas fired boiler (#11) are 

subject to a New Source Performance Standard (NSPS) for IndustrialCommercial-Institutional Steam Generating Units, 40 CFR 60, Subparts A, 

and Db. The Illinois EPA is administering NSPS in Illinois on behalf 

of the USEPA under a delegation agreement. 

 b. The emissions from each boiler shall not exceed the applicable limits 

pursuant to the NSPS. 

 c. At all times, the Permittee shall maintain and operate each boiler, 

including associated air pollution control equipment, in a manner 

consistent with good air pollution control practice for minimizing 

emissions, as required per NSPS, 40 CFR 60.11(d). 

6a. Emissions from the boilers shall not exceed the limits in Table I. The 

limits in Table I are based upon the emission rates and the maximum 

firing rate specified in the permit application consistent with the air 

quality analysis submitted by the Permittee to comply with the PSD 

rules. Compliance with these limits shall be determined as a 3 - hour 

average, consistent with testing and monitoring as required by 

Conditions 8, 9, 10, and 11. 

 b. Emissions of particulate matter from the new limestone unloading rail dump 

and limestone silo #4 shall not exceed 1.71 pound/hour (each) and 7.51 

tons/year (each). 

7a. New emission units covered by this Permit may each be operated under 

this construction permit for a startup/shakedown period of 365 days* 

after completion of construction. During this period , notwithstanding 

Condition 2(a)(ii), the SO2 reduction for a CFB boiler need only comply 

with the reduction requirement of the NSPS, 40 CFR Part 60, Subpart Db, 

following initial performance testing to the extent authorized by the 

Illinois EPA in conjunction with a request from the Permittee to make 

improvements to boiler equipment and operation to facilitate compliance 

with the SO2 reduction requirement. 

* For the new CFB boilers, this period of time may be extended by 

the Illinois EPA for up to an additional 365 days upon written 

request by the Permittee as needed to reasonably accommodate 

unforeseen difficulties in the startup of these boilers.

6. The nitrogen oxides and carbon monoxide concentration in the effluent 

stream of the temporary boiler shall be measured by an approved 

independent testing service, within 45 days of a written request by the 

Agency for such a test. The Agency will require this test if, based on 

observations by Field personnel, the temporary boiler is poorly 

maintained or operated so as to make compliance. 

7. As a consequence of the above conditions, this permit is issued based 

on the addition of the above referenced package boiler not constituting 

a major modification in order to limit NOx emissions to below those at 

which the Agency believes Prevention of Significant Deterioration 

rules, CFR 52.21 would apply. The emissions of NOx are below the 

significance level of 40 tons/yr. This shall be accomplished by 

operating 172 million Btu per hour package boiler as a temporary unit.

Findings

1a. Archer Daniels Midland Co. (ADM) operates boilers to supply steam for 

its grain processing operations and to generate electricity. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-378 

 b. ADM has requested a permit to construct two circulating fluidized bed 

(CFB) boilers, each with a baghouse, a selective non-catalytic 

reduction system and limestone injection, two gas fired boilers with 

low NOx burners and flue gas recirculation, two ash silos with baghouses 

and one limestone storage silo. 

 c. ADM has also requested a revised permit for increased operating rate of 

its existing CFB boiler with existing baghouse, and 

 d. ADM has also requested a revised permit for a usage increase without 

restrictions on hours of use for eight gas fired boilers (Nos. 3-10) in 

conjunction with special condition 3d. They are permitted for use only 

to the extent that the six existing CFB boilers are not in service. 

2. The plant is located in Decatur Township in Macon County. The area is 

currently designated attainment for all air quality standards. The 

county has a class II designation for Prevention of Significant 

Deterioration (PSD) permit review. 

3a. The plant is a major source under PSD rules. The proposed project will 

increase potential annual emissions of 7,540 tons/year of sulfur 

dioxide (SO2), 1,730 tons/yr of nitrogen oxides (NOx), 296 tons/yr of 

particulate matter, 1,350 tons/yr of carbon monoxide (CO), 356 tons/yr 

of volatile organic compounds (VOC), and 72.8 tons/yr of fluorides. 

The project is therefore subject to PSD review as a major modification 

for the above contaminants. 

4. The new and modified boilers and associated new equipment must be 

operated so that emissions are in compliance with (i) all applicable 

Pollution Control Board emission standards, (ii) federal New Source 

performance standards for emissions of SO2, NOx and PM, (iii) Best 

Available Control Technology (BACT) for emissions of SO2, NOx, PM, CO, 

VOC, and fluorides as set in conditions of this permit. The 

application submitted by ADM, as reviewed by the IEPA shows that the 

project will comply with these requirements. Emissions of fluorides 

are addressed by limits on PM and SO2. 

5. The air quality analysis submitted by ADM and reviewed by the IEPA 

shows that this project will not cause a violation of the ambient air 

quality standard. The air quality analysis also shows compliance with 

the allowable increment for PM, SO2 and NOx. 

6. The IEPA has determined that the application for the proposed project 

complies with all applicable Pollution Control Board Regulations the 

federal New Source Performance Standards 40 CFR 60, Subpart Db, and the 

federal Prevention of Significant Deterioration of Air Quality 

Regulations (PSD), 40 CFR 52.21. 

7. A copy of the application, and the Agency's review of the application 

and a draft of this permit were placed in a location in the Decatur

Decatur, Illinois 62526 

Application No.: 93120004 

I.D. No.: 115015AAE 

Applicant’s Designation: VITAMIN -E1 

Date Received: June 24, 1997 

Subject: Vitamin E Production 

Date Issued: October 22, 1998 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of a 

Vitamin E Production Plant, including the equipment listed in Attachment A as 

described in the above referenced application. This Permit is subject to 

standard conditions attached hereto and the following special condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct the above referenced project, in that the Illinois Environmental 

Protection Agency (Agency) finds that the application fulfills all applicable 

requirements of 40 CFR 52.21. This approval is issued pursuant to the Clean 

Air Act, as amended, 42 U.S.C. 7401 et. seq., the Federal regulations 

promulgated thereunder at 40 CFR 52.21 for Prevention of Significant 

Deterioration of Air Quality (PSD), and a Delegation of Authority agreement 

between the United States Environmental Protection Agency and the Illinois 

EPA for the administration of the PSD Program. This approval becomes 

effective in accordance with the provisions of 40 CFR 124.15 and may be 

appealed in accordance with the provisions of 40 CFR 124.19. This approval 

is also based upon and subject to the following findings and the conditions 

which follow: 

1. Archer Daniels Midland (ADM) has requested a revised construction 

permit for the Vitamin E plant (Plant) at its Decatur manufacturing 

complex. The revised permit would allow for greater volatile organic 

material (VOM) emissions from the plant. In conjunction with this 

revision, ADM will install additional control for VOM emissions, 

including a secondary scrubber on the existing mineral oil scrubber and 

a separate two-stage scrubber control system for methylation. This 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-392 

permit also recognizes improvements already made in the plant including 

lowering the operating temperatures of the condensers on methylation 

and changes in the components and practices to lower losses from 

leaking valves and other components in VOM service. 

2. The source is located in Decatur Township in Macon county. The area is 

designated attainment for all pollutants. 

3. The requested permit would allow annual VOM emissions of 710 tons from 

the plant. The plant would therefore be subject to PSD as a major 

modification to an existing source for VOM emissions. 

4. After reviewing the materials submitted by ADM, Illinois EPA has 

determined that the plant, as proposed, would (i) be in compliance with 

applicable Board emission standards and (ii) utilize Best Available 

Control Technology (BACT) on emissions of VOM. 

5. The Illinois EPA has determined that the plant, as proposed, would 

comply with all applicable Illinois Air Pollution Board Regulations and 

the federal Prevention of Significant Deterioration of Air Quality 

Regulations (PSD), 40 CFR 52.21. 

6. A copy of the application and the Illinois EPA’s formal review of the 

application and a draft of this permit were placed in a location in the 

vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing this approval subject to the following conditions 

and consistent with the specifications and data included in the application. 

Any departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization by Illinois 

EPA. 

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply, unless 

superseded by the following special conditions. 

2a. All process vents discharging VOM, hot wells (vacuum systems) 

associated with process units that use VOM solvent, and all VOL solvent 

tanks shall be enclosed and ducted through a closed vent system to a 

VOM emission control system. 

 b. All process units that entail use of VOM solvent shall be designed, 

constructed, and operated to prevent introduction of air into the 

process unit and maintain low hourly exhaust flow rate (less than 200 

acfm total, hourly average) to the VOM control systems during normal 

operating conditions.

 c. The VOM emission control systems shall be designed and constructed to 

achieve at least 98% control of VOM comparing the amount of VOM 

introduced into the processes and the emissions to the atmosphere. 

These control systems shall be operated and maintained in conformance 

with good air pollution practice. 

3a. The Permittee shall implement the following practices for components 

and materials to minimize VOM emission losses from leaking components 

unless and until an equivalent practice is approved by the Illinois 

EPA: 

i. Gaskets for inspection ports and manways shall be of low leak 

material such as GYLON TM, in which a non-rubber contact material 

or seal encases a resilient core; and 

ii. Open-ended valves shall only be present as needed for routine 

sampling of a process. 

 b. The Permittee shall implement a Leak Detection and Repair Program for 

components in VOM service in the process units of the plant. This 

program shall include the following elements as a minimum: 

i. Scope: The program covers all components that are in VOM service 

in the process operations, other than components in vacuum 

service and components equipped with a closed vent system ducted 

to a VOM control system, where the term component includes valves 

(conventional valves and multi-port “octopus” valves), pumps and 

agitators (shaft seals), flanges, other connectors (inspection 

ports, manways, sight glasses, etc.), closed vent systems, and 

pressure relief devices. 

ii. Definitions: 

Leak: 

An instrument reading of 10,000 ppm or greater for components 

other than pressure relief devices, an instrument reading of 500 

ppm or greater for pressure relief devices, or observation of 

leaking material from a component as detected by sight, smell, or 

sound is considered a leak. 

Low-Leak Design Pump: 

A pump fitted with double mechanical inert gas pressurized seals, 

equipped with a permanent gauge for seal pressure and that is 

operated and maintained consistent with good practice, or other 

similar pump design as approved by the Illinois EPA that both 

minimizes leaks and directly reveals the presence of a leak.

Application No.: 96030038 

1-394 

iii. Inspections are conducted on at least the following basis for 

components using applicable instrument and source survey 

procedures specified by USEPA Method 21 (except that daily manual 

calibration is not required if the instrument is selfcalibrating) or the screening procedures in such methods. 

Inspections are as follows: 

Quarterly for valves (except for conventional valves as USEPA 

skip-check criteria and alternative practices established in 40 

CFR 60.483-2 (NSPS for SOCMI Leaks) are satisfied) and pumps 

(except pumps that are of low leak design); 

Annually for closed vent systems; 

Within a week for a pressure relief device after it experiences a 

pressure release; 

Within a week for the flanges and other connectors in a 

particular area, system or feature after such components are 

involved in repair, maintenance, alteration or other activity 

that has the potential to result in a leak from flanges or other 

connectors, including resealing of a manway after entry to a 

vessel, if absence of leaking components was not verified as a 

final step in such activity by use of a soap solution or other 

comparable technique; and 

Within a week after repair of a component for which a leak was 

detected and could not be readily repaired within one hour. 

iv. Repairs: Repairs are made as soon as practicable but not later 

than the following: 

For a component other than a pump or valve, if a process unit 

shutdown is necessary to accomplish the repair, not later than 

the end of the next process unit shutdown. 

For a pump or valve, if a process unit shutdown is necessary to 

accomplish the repair, not later than the end of the next process 

unit shutdown or 6 months, whichever occurs first, except that 

further delay of repair of a valve is allowed (beyond the next 

process unit shutdown) if reasonable supplies of repair parts or 

replacement valves are maintained but these supplies are 

depleted, in which case repair of a valve shall be accomplished 

not later than 6 months after the first process unit shutdown or 

1 year after detection of the leak, whichever occurs first. 

v. Tagging: A leaking component is “tagged” if it cannot be readily 

repaired within one hour of detection of a leak, which tag 

includes the date the leak was detected and the date the leak was 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-395 

repaired and which tag is only removed after the repaired 

component is inspected. 

vi. Records: Records are maintained that: 

Facilitate correct and consistent identification of the 

components that are covered by the program, including at a 

minimum maintaining an up to date Process and Instrumentation 

Diagrams for the plant available. 

Verify performance of required inspections, including date, 

personnel, proper implementation of inspection methods, purpose 

or scope of inspection, covered components and results. 

Document each component leak that is identified, including 

identification of the component and the nature of the leak, and 

verify prompt repair of the leak, including the date the repair 

is completed and detailed explanation of the required actions for 

a leak repair that could not be completed within 30 days, further 

explanation if a repair could not be completed until process unit 

shutdown or thereafter, and the date required inspection of the 

component was performed following repair. 

Compile the results of the program, including fulfillment of 

skip-check criteria for conventional valves when relied upon. 

Identify each deviation from required practices, with appropriate 

identification, description and explanation. 

Document proper operation, maintenance, and repair of low-leak 

design pumps. 

vii. Revisions: The minimum provisions for tagging and recordkeeping, 

as specified above, may be revised by the Illinois EPA in future 

operating permits for the plant to the extent that the Permittee 

demonstrates that effective detection and repair of leaking 

components is still reasonably assured by the revised provisions. 

Conditions 2 and 3 address Best Available Control Technology as required by 

Section 165 of the Clean Air Act. 

4a. Emissions of VOM by the plant shall not exceed 710 tons per year. 

 b. Emissions by the plant of VOM compounds that are soluble in water,

Attn: Andrea Paulek 

4666 Faries Parkway 

Decatur, Illinois 62526 

Application No.: 99030077 I.D. No.: 115015AAE 

Applicant’s Designation: XG Transfer Date Received: July 25, 2005 

Subject: Xanthan Gum Production 

Date Issued: March 2, 2006 

Location: 4666 Faries Parkway, Decatur 

Permit is hereby granted to the above-designated Permittee to CONSTRUCT 

emission source(s) and/or air pollution control equipment consisting of a 

Xanthan Gum Production Plant, including the equipment listed in Attachment A 

as described in the above referenced application. This Permit is subject to 

standard conditions attached hereto and the following special condition(s): 

In conjunction with this permit, approval is given with respect to the 

Prevention of Significant Deterioration of Air Quality Regulations (PSD) to 

construct the above referenced project, in that the Illinois Environmental 

Protection Agency (Agency) finds that the application fulfills all applicable 

requirements of 40 CFR 52.21. This approval is issued pursuant to the Clean 

Air Act, as amended, 42 U.S.C. 7401 et. seq., the Federal regulations 

promulgated thereunder at 40 CFR 52.21 for Prevention of Significant 

Deterioration of Air Quality (PSD), and a Delegation of Authority agreement 

between the United States Environmental Protection Agency and the Illinois 

EPA for the administration of the PSD Program. This approval becomes 

effective in accordance with the provisions of 40 CFR 124.15 and may be 

appealed in accordance with the provisions of 40 CFR 124.19. This approval 

is also based upon and subject to the following findings and the conditions, 

which follow: 

1. Archer Daniels Midland (ADM) has requested a joint construction and 

operating permit for the Xanthan Gum plant (Plant) at its Decatur 

manufacturing complex. The permit would allow for greater volatile 

organic material (VOM) emissions from the plant. The VOM emissions 

from this plant consist of Isopropyl Alcohol (IPA). 

2. The source is located in Decatur Township in Macon County. The area is 

designated attainment for all pollutants. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

1-450 

3. The requested permit would allow annual VOM emissions of 500 tons from 

the plant. The plant would therefore be subject to PSD as a major 

modification to an existing source for VOM emissions. 

4. After reviewing the materials submitted by ADM, Illinois EPA has 

determined that the plant, as proposed, would (i) be in compliance with 

applicable Board emission standards and (ii) utilize Best Available 

Control Technology (BACT) on emissions of VOM. 

5. The Illinois EPA has determined that the plant, as proposed, would 

comply with all applicable Illinois Air Pollution Board Regulations and 

the federal Prevention of Significant Deterioration of Air Quality 

Regulations (PSD), 40 CFR 52.21. 

6. A copy of the application and the Illinois EPA’s formal review of the 

application and a draft of this permit were placed in a location in the 

vicinity of the project, and the public was given notice and an 

opportunity to examine this material and to submit comments and to 

request a public hearing on this matter. 

The Illinois EPA is issuing this approval subject to the following conditions 

and consistent with the specifications and data included in the application. 

Any departure from the conditions of this approval or terms expressed in the 

application would need to receive prior written authorization by Illinois 

EPA. 

1. Standard conditions for issuance of construction permits, attached 

hereto and incorporated herein by reference, shall apply, unless 

superseded by the following special conditions. 

2a. All process vents discharging VOM shall be enclosed and ducted through 

a closed vent system to a VOM emission control system. 

 b. The VOM emission control systems shall be designed, constructed and 

maintained to achieve at least 98% control of VOM comparing the amount 

of VOM introduced into the processes and the emissions to the 

atmosphere. These control systems shall be operated and maintained in 

conformance with good air pollution control practices. 

3a. The Permittee shall use open-ended valves only as needed for routine 

sampling of process unless and until an equivalent practice is approved 

by the Illinois EPA to minimize VOM emission losses from leaks. 

 b. The Permittee shall implement a Leak Detection and Repair Program for 

components in VOM service in the process units of the plant. This 

program shall include the following elements as a minimum: 

i. Scope: The program covers all components that are in VOM service 

in the process operations, other than components in vacuum 

service and components equipped with a closed vent system ducted

to a VOM control system, where the term component includes 

valves, pumps and agitators (shaft seals), flanges, other 

connectors (inspection ports, manways, sight glasses, etc.), 

closed vent systems, and pressure relief devices. 

ii. Definitions: 

Closed Vent System: A system that is not open to the atmosphere 

and that is composed of piping, connections, and, if necessary, 

flow inducing devices that transport gas or vapor from a piece or 

pieces of equipment to a control device. If gas or vapor from 

regulated equipment is routed to a process, the process shall not 

be considered a closed vent system. 

In Vacuum Service: Equipment is operated at an internal pressure 

at least 5 kilopascals (kPa) below ambient pressure. 

In VOM Service: A piece of equipment that contains or contacts a 

process fluid that is at least 10% VOM by weight. 

Leak: An instrument reading of 10,000 PPM or greater for 

components other than pressure relief devices, an instrument 

reading of 500 PPM or greater for pressure relief devices, or 

observation of leaking material from a component as detected by 

sight, smell, or sound is considered a leak. 

Low-Leak Design Pump: A pump fitted with double mechanical fluid 

pressurized seals, equipped with a permanent gauge* for seal 

pressure and that is operated and maintained consistent with good 

practice, or other similar pump design as approved by the 

Illinois EPA that both minimizes leaks and directly reveals the 

presence of a leak. 

* The pressure gauge may be installed on the individual pump or 

 as part of the seal fluid system. 

iii. Monitoring 

Monitoring: Monitoring conducted on at least the following basis 

for components using applicable instrument and source survey 

procedures specified by USEPA Method 21 (except that daily manual 

calibration is not required if the instrument is 

self-calibrating) or the screening procedures in such methods. 

Inspections are as follows: 

A. Quarterly for valves (except for conventional valves as 

USEPA skip-check criteria and alternative practices 

established in 40 CFR 60.483-2 (NSPS for SOCMI Leaks) are 

satisfied) and pumps (except pumps that are of low leak 

design); 
CAAPP PERMIT

Application No.: 96030038 

1-452 

B. Annually for closed vent systems; 

C. Within a week for a pressure relief device after it 

experiences a pressure release; 

D. Within a week for the flanges and other connectors in a 

particular area, system or feature after such components 

are involved in repair, maintenance, alteration or other 

activity that has the potential to result in a leak from 

flanges or other connectors, including resealing of a 

manway after entry to a vessel, if absence of leaking 

components was not verified as a final step in such 

activity by use of a soap solution or other comparable 

technique; and 

E. Within a week after repair of a component for which a leak 

was detected and could not be readily repaired within one 

hour. 

iv. Repairs: Repairs made as soon as practicable but not later than 

the following: 

A. For a component other than a pump or valve, if a process 

unit shutdown is necessary to accomplish the repair, not 

later than the end of the next process unit shutdown. 

B. For a pump or valve, if a process unit shutdown is 

necessary to accomplish the repair, not later than the end 

of the next process unit shutdown or 6 months, whichever 

occurs first, except that further delay of repair of a 

valve is allowed (beyond the next process unit shutdown) if 

reasonable supplies of repair parts or replacement valves 

are maintained but these supplies are depleted, in which 

case repair of a valve shall be accomplished not later than 

6 months after the first process unit shutdown or 1 year 

after detection of the leak, whichever occurs first. 

v. Tagging: Tagging of leaking component if it cannot be readily 

repaired within one hour of detection of a leak, which tag 

includes the date the leak was detected and the date the leak was 

repaired and which tag is only removed after the repaired 

component is inspected. 

vi. Records: Records are maintained that: 

A. Facilitate correct and consistent identification of the 

components that are covered by the program, including, at a 

minimum up to date Process Diagram for the plant.

B. Verify performance of required inspections, including date, 

personnel, proper implementation of inspection methods, 

purpose or scope of inspection, covered components and 

their leak status(i.e. leak or no leak). 

C. Document each component leak that is identified, including 

identification of the component and the nature of the leak, 

and verify prompt repair of the leak, including the date 

the repair is completed and detailed explanation of the 

required actions for a leak repair that could not be 

completed within 30 days, further explanation if a repair 

could not be completed until process unit shutdown or 

thereafter, and the date required inspection of the 

component was performed following repair. 

D. Compile the results of the program, including fulfillment of 

skip-check criteria for conventional valves when relied upon. 

E. Identify each deviation from required practices, with 

appropriate identification, description and explanation. 

F. Document proper operation, maintenance, and repair of 

low-leak design pumps. 

vii. Revisions: The minimum provisions for tagging and recordkeeping, 

as specified above, may be revised by the Illinois EPA in future 

operating permits for the plant to the extent that the Permittee 

demonstrates that effective detection and repair of leaking 

components is still reasonably assured by the revised provisions. 

4a. The Permittee shall implement the following practices to minimize VOM 

losses from opening vessels and other units in the plant that may 

contain process materials that contain VOM. Prior to opening other 

vessels to the atmosphere, residual VOM that may be present shall be 

purged in accordance with written operating procedures developed to 

minimize loss of VOM to the atmosphere. These procedures shall include 

the following procedures that shall be updated on a regular basis to 

reflect the Permittee’s experience with maintenance and repair of the 

plant unless and until an equivalent practice is approved by the 

Illinois EPA: 

i. Prior to opening a delumper, screw press or rotary screen to the 

atmosphere, the vessel shall be purged to clear residual VOM. 

The initial purge shall be performed for a minimum of 15 minutes. 

If residual VOM remains, as determined by smell, an additional 

15-minute purge shall be performed. All vapors resulting from 

the purging of the equipment shall be vented to the IPA scrubber. 

ii. Prior to opening a turbo dryer to the atmosphere, the dryer shall 

be cooled to at least 100°F. This cooling/purging operation

shall be performed for a minimum of 30 minutes. If residual VOM 

remains and/or the dryer temperature is above 100°F, an 

additional 30-minute purge shall be performed. All purge vapors 

shall be vented to the turbo-dryer scrubber. 

 b. Any VOM containing material removed in bulk from equipment due to 

maintenance and repair procedures shall be handled in closed containers 

immediately upon removal from the process unit and disposed of in a 

manner that minimizes loss of VOM to the atmosphere if possible, e.g., 

reintroducing to the process. 

 c. All IPA, IPA containing waste and IPA containing product shall be 

stored in sealed, non-leaking containers. 

 d. The Permittee shall keep maintenance log(s) for the plant that includes 

as a minimum:

3. Emission Limitations 

a. This permit does not revise the limitations on VOM emissions from 

the plant established in the PSD permit, as follows: 

i. Total plant emissions of VOM shall not exceed 500 

tons per year. Compliance with this limit shall be 

determined on a rolling 12 month basis, calculated monthly. 

ii. Stack emissions of VOM from the plant shall not 

exceed 9.0 lb/hr and 39.42 tons per year. Compliance with 

this limit shall be determined at the exhaust of the packed 

bed scrubber. 

iii. Total plant emissions of VOM shall not exceed 300 tons per 

year on a 3 year rolling average. Compliance with this 

limit shall be determined on a rolling three year basis, 

calculated monthly. 

4. Non-Applicability Provisions 

a. i. This Permit is issued based on the increase in emissions of 

VOM from the modifications to the plant, not exceeding the 

27.5 tons/year. As a result, this permit is issued based 

on this project not being a major modification subject to 

the PSD rules for emissions of VOM because it will not be 

accompanied by significant increases in emissions, as 

defined under the PSD rules. (See Attachment 1) 

ii. The Permittee shall, for a period of 10 years following 

resumption of regular operation after the modifications 

entailed in this project are made, operate the affected 

changes in such a manner that this project does not result 

in a significant increase in emissions of VOM and qualify 

as a major modification for VOM. 

iii. The Permittee shall also fulfill the applicable 

recordkeeping and reporting requirements of the PSD rules, 

40 CFR 52.21(r)(6), for this project. 

5. The Permittee is allowed to operate the affected changes 

under this construction permit until final action is taken 

to incorporate these emission units in a revision to or 

renewal of their CAAPP permit.

10.5 Attachment 5 - Guidance on Revising This Permit 

The Permittee must submit an application to the Illinois EPA 

using the appropriate revision classification in accordance with 

Sections 39.5(13) and (14) of the Act and 35 IAC 270.302. 

Specifically, there are currently three classifications for 

revisions to a CAAPP permit. These are: 

1. Administrative Permit Amendment; 

2. Minor Permit Modification; and 

3. Significant Permit Modification. 

The Permittee must determine, request, and submit the necessary 

information to allow the Illinois EPA to use the appropriate 

procedure to revise the CAAPP permit. A brief explanation of 

each of these classifications follows. 

1. Administrative Permit Amendment

• Corrects typographical errors; 

• Identifies a change in the name, address, or phone 

number of any person identified in the permit, or 

provides a similar minor administrative change at the 

source; 

• Requires more frequent monitoring or reporting by the 

Permittee; 

• Allows for a change in ownership or operational 

control of the source where no other change in the 

permit is necessary, provided that a written 

agreement containing a specific date for transfer of 

permit responsibility, coverage, and liability 

between the current and new Permittees has been 

submitted to the Illinois EPA; 

• Incorporates into the CAAPP permit a construction 

permit, provided the conditions of the construction 

permit meet the requirements for the issuance of 

CAAPP permits; or 

• Incorporates into the CAAPP permit revised 

limitations or other requirements resulting from the 

application of an approved economic incentives rule, 

marketable permits rule, or generic emissions trading 

rule.

I.D. Number: 115015AAE 

Application No.: 96030038 

5-2 

2. Minor Permit Modification

• Do not violate any applicable requirement; 

• Do not involve significant changes to existing 

monitoring, reporting, or recordkeeping requirements 

in the permit; 

• Do not require a case-by-case determination of an 

emission limitation or other standard, or a 

source-specific determination of ambient impacts, or 

a visibility or increment analysis; 

• Do not seek to establish or change a permit term or 

condition for which there is no corresponding 

underlying requirement and which avoids an applicable 

requirement to which the source would otherwise be 

subject. Such terms and conditions include: 

• A federally enforceable emissions cap assumed 

to avoid classification as a modification 

under any provision of Title I of the CAA; and 

• An alternative emissions limit approved 

pursuant to regulations promulgated under 

Section 112(i)(5) of the CAA. 

• Are not modifications under any provision of Title I 

of the CAA; and 

• Are not required to be processed as a significant 

permit modification. 

An application for a minor permit modification shall 

include the following: 

• A description of the change, the emissions resulting 

from the change, and any new applicable requirements 

that will apply if the change occurs; 

• The source’s suggested draft permit/conditions; 

• Certification by a responsible official that the 

proposed modification meets the criteria for use of 

minor permit modification procedures and a request 

that such procedures be used; and 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

5-3 

• Information as contained on form 271-CAAPP for the 

Illinois EPA to use to notify USEPA and affected 

States. 

3. Significant Permit Modification

• Applications that do not qualify as either minor

10.7 Attachment 7 - Guidance on Renewing This Permit 

Timeliness - Pursuant to Section 39.5(5)(n) of the Act and 35 IAC 

270.301(d), a source must submit to the Illinois EPA a complete 

CAAPP application for the renewal of a CAAPP permit not later 

than 9 months before the date of permit expiration of the 

existing CAAPP permit in order for the submittal to be deemed 

timely. Note that the Illinois EPA typically sends out renewal 

notices approximately 18 months prior to the expiration of the 

CAAPP permit. 

The CAAPP application must provide all of the following 

information in order for the renewal CAAPP application to be 

deemed complete by the Illinois EPA: 

1. A completed renewal application form 200-CAAPP, 

APPLICATION FOR CAAPP PERMIT. 

2. A completed compliance plan form 293-CAAPP, COMPLIANCE 

PLAN/SCHEDULE OF COMPLIANCE FOR CAAPP PERMIT. 

3. A completed compliance certification form 296-CAAPP, 

COMPLIANCE CERTIFICATION, signed by the responsible 

official. 

4. Any applicable requirements that became effective during 

the term of the permit and that were not included in the 

permit as a reopening or permit revision. 

5. If this is the first time this permit is being renewed and 

this source has not yet addressed CAM, the application 

should contain the information on form 464-CAAPP, 

COMPLIANCE ASSURANCE MONITORING (CAM) PLAN. 

6. Information addressing any outstanding transfer agreement 

pursuant to the ERMS. 

7. a. If operations of an emission unit or group of 

emission units remain unchanged and are accurately 

depicted in previous submittals, the application may 

contain a letter signed by a responsible official 

that requests incorporation by reference of existing 

information previously submitted and on file with the 

Illinois EPA. This letter must also include a 

statement that information incorporated by reference 

is also being certified for truth and accuracy by the 

responsible official’s signing of the form 200-CAAPP, 

APPLICATION FOR CAAPP PERMIT and the form 296-CAAPP, 

COMPLIANCE CERTIFICATION. The boxes should be marked 

yes on form 200-CAAPP, APPLICATION FOR CAAPP PERMIT, 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

7-2 

as existing information is being incorporated by 

reference. 

b. If portions of current operations are not as 

described in previous submittals, then in addition to 

the information above for operations that remain 

unchanged, the application must contain the necessary 

information on all changes, e.g., discussion of 

changes, new or revised CAAPP forms, and a revised 

fee form 292-CAAPP, FEE DETERMINATION FOR CAAPP 

PERMIT, if necessary. 

8. Information about all off-permit changes that were not 

prohibited or addressed by the permit to occur without a 

permit revision and the information must be sufficient to 

identify all applicable requirements, including 

monitoring, recordkeeping, and reporting requirements, for 

such changes. 

9. Information about all changes made under 40 CFR 

70.4(b)(12)(i) and (ii) that require a 7-day notification 

prior to the change without requiring a permit revision. 

The Illinois EPA will review all applications for completeness 

and timeliness. If the renewal application is deemed both timely 

and complete, the source shall continue to operate in accordance 

with the terms and conditions of its CAAPP permit until final 

action is taken on the renewal application. 

Notwithstanding the completeness determination, the Illinois EPA 

may request additional information necessary to evaluate or take 

final action on the CAAPP renewal application. If such 

additional information affects your allowable emission limits, a 

revised form 292-CAAPP, FEE DETERMINATION FOR CAAPP PERMIT must 

be submitted with the requested information. The failure to 

submit to the Illinois EPA the requested information within the 

time frame specified by the Illinois EPA, may force the Illinois 

EPA to deny your CAAPP renewal application pursuant to Section 

39.5 of the Act. 

Application forms may be obtained from the Illinois EPA website 

at http://www.epa.state.il.us/air/forms.html.

10.9 Attachment 9 Applicable National Emission Standards for 

Hazardous Air Pollutants (NESHAP) 

TITLE 40--PROTECTION OF ENVIRONMENT

CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY 

PART 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS 

FOR SOURCE CATEGORIES

Subpart A--General Provisions

Source: 59 FR 12430, Mar. 16, 1994, unless otherwise noted. 

Sec. 63.1 Applicability. 

(a) General. 

(1) Terms used throughout this part are defined in Sec. 

63.2 or in the Clean Air Act (Act) as amended in 

1990, except that individual subparts of this part 

may include specific definitions in addition to or 

that supersede definitions in Sec. 63.2. 

(2) This part contains national emission standards for 

hazardous air pollutants (NESHAP) established 

pursuant to section 112 of the Act as amended 

November 15, 1990. These standards regulate specific 

categories of stationary sources that emit (or have 

the potential to emit) one or more hazardous air 

pollutants listed in this part pursuant to section 

112(b) of the Act. This section explains the 

applicability of such standards to sources affected 

by them. The standards in this part are independent 

of NESHAP contained in 40 CFR part 61. The NESHAP in 

part 61 promulgated by signature of the Administrator 

before November 15, 1990 (i.e., the date of enactment 

of the Clean Air Act Amendments of 1990) remain in 

effect until they are amended, if appropriate, and 

added to this part. 

(3) No emission standard or other requirement established 

under this part shall be interpreted, construed, or 

applied to diminish or replace the requirements of a 

more stringent emission limitation or other 

applicable requirement established by the 

Administrator pursuant to other authority of the Act 

(including those requirements in part 60 of this 

chapter), or a standard issued under State authority. 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-2 

(4) The provisions of this subpart (i.e., subpart A of 

this part) apply to owners or operators who are 

subject to subsequent subparts of this part, except 

when otherwise specified in a particular subpart or 

in a relevant standard. The general provisions in 

subpart A eliminate the repetition of requirements 

applicable to all owners or operators affected by 

this part. The general provisions in subpart A do 

not apply to regulations developed pursuant to 

section 112(r) of the amended Act, unless otherwise 

specified in those regulations. 

(5) [Reserved] 

(6) To obtain the most current list of categories of 

sources to be regulated under section 112 of the Act, 

or to obtain the most recent regulation promulgation 

schedule established pursuant to section 112(e) of 

the Act, contact the Office of the Director, Emission 

Standards Division, Office of Air Quality Planning 

and Standards, U.S. EPA (MD-13), Research Triangle 

Park, North Carolina 27711. 

(7) Subpart D of this part contains regulations that 

address procedures for an owner or operator to obtain 

an extension of compliance with a relevant standard 

through an early reduction of emissions of hazardous 

air pollutants pursuant to section 112(i)(5) of the 

Act. 

(8) Subpart E of this part contains regulations that 

provide for the establishment of procedures 

consistent with section 112(l) of the Act for the 

approval of State rules or programs to implement and 

enforce applicable Federal rules promulgated under 

the authority of section 112. Subpart E also 

establishes procedures for the review and withdrawal 

of section 112 implementation and enforcement 

authorities granted through a section 112(l) 

approval. 

(9) [Reserved] 

(10) For the purposes of this part, time periods specified 

in days shall be measured in calendar days, even if 

the word “calendar” is absent, unless otherwise 

specified in an applicable requirement. 

(11) For the purposes of this part, if an explicit 

postmark deadline is not specified in an applicable 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-3 

requirement for the submittal of a notification, 

application, test plan, report, or other written 

communication to the Administrator, the owner or 

operator shall postmark the submittal on or before 

the number of days specified in the applicable 

requirement. For example, if a notification must be 

submitted 15 days before a particular event is 

scheduled to take place, the notification shall be 

postmarked on or before 15 days preceding the event; 

likewise, if a notification must be submitted 15 days 

after a particular event takes place, the 

notification shall be postmarked on or before 15 days 

following the end of the event. The use of reliable 

non-Government mail carriers that provide indications 

of verifiable delivery of information required to be 

submitted to the Administrator, similar to the 

postmark provided by the U.S. Postal Service, or 

alternative means of delivery agreed to by the 

permitting authority, is acceptable. 

(12) Notwithstanding time periods or postmark deadlines 

specified in this part for the submittal of 

information to the Administrator by an owner or 

operator, or the review of such information by the 

Administrator, such time periods or deadlines may be 

changed by mutual agreement between the owner or 

operator and the Administrator. Procedures governing 

the implementation of this provision are specified in 

Sec. 63.9(i). 

(13) Special provisions set forth under an applicable 

subpart of this part or in a relevant standard 

established under this part shall supersede any 

conflicting provisions of this subpart. 

(14) Any standards, limitations, prohibitions, or other 

federally enforceable requirements established 

pursuant to procedural regulations in this part 

[including, but not limited to, equivalent emission 

limitations established pursuant to section 112(g) of 

the Act] shall have the force and effect of 

requirements promulgated in this part and shall be 

subject to the provisions of this subpart, except 

when explicitly specified otherwise. 

(b) Initial applicability determination for this part. 

(1) The provisions of this part apply to the owner or 

operator of any stationary source that— 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-4 

(i) Emits or has the potential to emit any 

hazardous air pollutant listed in or pursuant 

to section 112(b) of the Act; and 

(ii) Is subject to any standard, limitation, 

prohibition, or other federally enforceable 

requirement established pursuant to this part. 

(2) In addition to complying with the provisions of this 

part, the owner or operator of any such source may be 

required to obtain an operating permit issued to 

stationary sources by an authorized State air 

pollution control agency or by the Administrator of 

the U.S. Environmental Protection Agency (EPA) 

pursuant to title V of the Act (42 U.S.C. 7661). For 

more information about obtaining an operating permit, 

see part 70 of this chapter. 

(3) An owner or operator of a stationary source that 

emits (or has the potential to emit, without 

considering controls) one or more hazardous air 

pollutants who determines that the source is not 

subject to a relevant standard or other requirement 

established under this part, shall keep a record of 

the applicability determination as specified in Sec. 

63.10(b)(3) of this subpart. 

(c) Applicability of this part after a relevant standard has 

been set under this part. 

(1) If a relevant standard has been established under 

this part, the owner or operator of an affected 

source shall comply with the provisions of this 

subpart and the provisions of that standard, except 

as specified otherwise in this subpart or that 

standard. 

(2) If a relevant standard has been established under 

this part, the owner or operator of an affected 

source may be required to obtain a title V permit 

from the permitting authority in the State in which 

the source is located. Emission standards 

promulgated in this part for area sources will 

specify whether— 

(i) States will have the option to exclude area 

sources affected by that standard from the 

requirement to obtain a title V permit (i.e., 

the standard will exempt the category of area 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-5 

sources altogether from the permitting 

requirement); 

(ii) States will have the option to defer 

permitting of area sources in that category 

until the Administrator takes rulemaking 

action to determine applicability of the 

permitting requirements; or 

(iii) Area sources affected by that emission 

standard are immediately subject to the 

requirement to apply for and obtain a title V 

permit in all States. If a standard fails to 

specify what the permitting requirements will 

be for area sources affected by that standard, 

then area sources that are subject to the 

standard will be subject to the requirement to 

obtain a title V permit without deferral. If 

the owner or operator is required to obtain a 

title V permit, he or she shall apply for such 

permit in accordance with part 70 of this 

chapter and applicable State regulations, or 

in accordance with the regulations contained 

in this chapter to implement the Federal title 

V permit program (42 U.S.C. 7661), whichever 

regulations are applicable. 

(3) [Reserved] 

(4) If the owner or operator of an existing source 

obtains an extension of compliance for such source in 

accordance with the provisions of subpart D of this 

part, the owner or operator shall comply with all 

requirements of this subpart except those 

requirements that are specifically overridden in the 

extension of compliance for that source. 

(5) If an area source that otherwise would be subject to 

an emission standard or other requirement established 

under this part if it were a major source 

subsequently increases its emissions of hazardous air 

pollutants (or its potential to emit hazardous air 

pollutants) such that the source is a major source 

that is subject to the emission standard or other 

requirement, such source also shall be subject to the 

notification requirements of this subpart. 

(d) [Reserved]

I.D. Number: 115015AAE 

Application No.: 96030038 

9-6 

(e) Applicability of permit program before a relevant standard 

has been set under this part. After the effective date of 

an approved permit program in the State in which a 

stationary source is (or would be) located, the owner or 

operator of such source may be required to obtain a title 

V permit from the permitting authority in that State (or 

revise such a permit if one has already been issued to the 

source) before a relevant standard is established under 

this part. If the owner or operator is required to obtain 

(or revise) a title V permit, he/she shall apply to obtain 

(or revise) such permit in accordance with the regulations 

contained in part 70 of this chapter and applicable State 

regulations, or the regulations codified in this chapter 

to implement the Federal title V permit program (42 U.S.C. 

7661), whichever regulations are applicable. 

Sec. 63.2 Definitions. 

The terms used in this part are defined in the Act or in this 

section as follows: 

Act means the Clean Air Act (42 U.S.C. 7401 et seq., as amended 

by Pub. L. 101-549, 104 Stat. 2399). 

Actual emissions is defined in subpart D of this part for the 

purpose of granting a compliance extension for an early reduction 

of hazardous air pollutants. 

Administrator means the Administrator of the United States 

Environmental Protection Agency or his or her authorized 

representative (e.g., a State that has been delegated the 

authority to implement the provisions of this part). 

Affected source, for the purposes of this part, means the 

stationary source, the group of stationary sources, or the 

portion of a stationary source that is regulated by a relevant 

standard or other requirement established pursuant to section 112 

of the Act. Each relevant standard will define the “affected 

source” for the purposes of that standard. The term “affected 

source,” as used in this part, is separate and distinct from any 

other use of that term in EPA regulations such as those 

implementing title IV of the Act. Sources regulated under part 

60 or part 61 of this chapter are not affected sources for the 

purposes of part 63. 

Alternative emission limitation means conditions established 

pursuant to sections 112(i)(5) or 112(i)(6) of the Act by the 

Administrator or by a State with an approved permit program. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-7 

Alternative emission standard means an alternative means of 

emission limitation that, after notice and opportunity for public 

comment, has been demonstrated by an owner or operator to the 

Administrator’s satisfaction to achieve a reduction in emissions 

of any air pollutant at least equivalent to the reduction in 

emissions of such pollutant achieved under a relevant design, 

equipment, work practice, or operational emission standard, or 

combination thereof, established under this part pursuant to 

section 112(h) of the Act. 

Alternative test method means any method of sampling and

(5) After the effective date of an emission standard 

promulgated under this part, the owner or operator of 

an unaffected existing area source that increases its 

emissions of (or its potential to emit) hazardous air 

pollutants such that the source becomes a major 

source that is subject to the emission standard shall 

comply by the date specified in the standard for 

existing area sources that become major sources. If 

no such compliance date is specified in the standard, 

the source shall have a period of time to comply with 

the relevant emission standard that is equivalent to 

the compliance period specified in that standard for 

other existing sources. This compliance period shall 

apply to existing area sources that become affected 

major sources regardless of whether the existing area 

source previously was affected by that standard. 

Notwithstanding the previous two sentences, however, 

if the existing area source becomes a major source by 

the addition of a new affected source or by 

reconstructing, the portion of the existing facility 

that is a new affected source or a reconstructed

(2) Determination of whether acceptable operation and 

maintenance procedures are being used will be based 

on information available to the Administrator which 

may include, but is not limited to, monitoring 

results, review of operation and maintenance 

procedures (including the startup, shutdown, and 

malfunction plan required in paragraph (e)(3) of this 

section), review of operation and maintenance 

records, and inspection of the source. 

(3) Startup, shutdown, and malfunction plan. 

(i) The owner or operator of an affected source 

shall develop and implement a written startup, 

shutdown, and malfunction plan that describes, 

in detail, procedures for operating and 

maintaining the source during periods of 

startup, shutdown, and malfunction and a 

program of corrective action for 

malfunctioning process and air pollution 

control equipment used to comply with the 

relevant standard. As required under Sec. 

63.8(c)(1)(i), the plan shall identify all 

routine or otherwise predictable CMS 

malfunctions. This plan shall be developed by 

the owner or operator by the source’s 

compliance date for that relevant standard. 

The plan shall be incorporated by reference 

into the source’s title V permit. The purpose 

of the startup, shutdown, and malfunction plan 

is to-- 

(A) Ensure that, at all times, owners or 

operators operate and maintain affected 

sources, including associated air 

pollution control equipment, in a manner 

consistent with good air pollution 

control practices for minimizing 

emissions at least to the levels required 

by all relevant standards; 

(B) Ensure that owners or operators are 

prepared to correct malfunctions as soon 

as practicable after their occurrence in 

order to minimize excess emissions of 

hazardous air pollutants; and 

(C) Reduce the reporting burden associated 

with periods of startup, shutdown, and 

malfunction (including corrective action

taken to restore malfunctioning process 

and air pollution control equipment to 

its normal or usual manner of operation). 

(ii) During periods of startup, shutdown, and 

malfunction, the owner or operator of an 

affected source shall operate and maintain 

such source (including associated air 

pollution control equipment) in accordance 

with the procedures specified in the startup, 

shutdown, and malfunction plan developed under 

paragraph (e)(3)(i) of this section. 

(iii) When actions taken by the owner or operator 

during a startup, shutdown, or malfunction 

(including actions taken to correct a 

malfunction) are consistent with the 

procedures specified in the affected source’s 

startup, shutdown, and malfunction plan, the 

owner or operator shall keep records for that 

event that demonstrate that the procedures 

specified in the plan were followed. These 

records may take the form of a “checklist,” or 

other effective form of recordkeeping, that 

confirms conformance with the startup, 

shutdown, and malfunction plan for that event. 

In addition, the owner or operator shall keep 

records of these events as specified in Sec. 

63.10(b) (and elsewhere in this part), 

including records of the occurrence and 

duration of each startup, shutdown, or 

malfunction of operation and each malfunction 

of the air pollution control equipment. 

Furthermore, the owner or operator shall 

confirm that actions taken during the relevant 

reporting period during periods of startup, 

shutdown, and malfunction were consistent with 

the affected source’s startup, shutdown and 

malfunction plan in the semiannual (or more 

frequent) startup, shutdown, and malfunction 

report required in Sec. 63.10(d)(5). 

(iv) If an action taken by the owner or operator 

during a startup, shutdown, or malfunction 

(including an action taken to correct a 

malfunction) is not consistent with the 

procedures specified in the affected source’s 

startup, shutdown, and malfunction plan, the 

owner or operator shall record the actions 

taken for that event and shall report such 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-34 

actions within 2 working days after commencing 

actions inconsistent with the plan, followed 

by a letter within 7 working days after the 

end of the event, in accordance with Sec. 

63.10(d)(5) (unless the owner or operator 

makes alternative reporting arrangements, in 

advance, with the Administrator (see Sec. 

63.10(d)(5)(ii))). 

(v) The owner or operator shall keep the written 

startup, shutdown, and malfunction plan on 

record after it is developed to be made 

available for inspection, upon request, by the 

Administrator for the life of the affected 

source or until the affected source is no 

longer subject to the provisions of this part. 

In addition, if the startup, shutdown, and 

malfunction plan is revised, the owner or 

operator shall keep previous (i.e., 

superseded) versions of the startup, shutdown, 

and malfunction plan on record, to be made 

available for inspection, upon request, by the 

Administrator, for a period of 5 years after 

each revision to the plan. 

(vi) To satisfy the requirements of this section to 

develop a startup, shutdown, and malfunction 

plan, the owner or operator may use the 

affected source’s standard operating 

procedures (SOP) manual, or an Occupational 

Safety and Health Administration (OSHA) or 

other plan, provided the alternative plans 

meet all the requirements of this section and 

are made available for inspection when 

requested by the Administrator. 

(vii) Based on the results of a determination made 

under paragraph (e)(2) of this section, the 

Administrator may require that an owner or 

operator of an affected source make changes to 

the startup, shutdown, and malfunction plan 

for that source. The Administrator may 

require reasonable revisions to a startup, 

shutdown, and malfunction plan, if the 

Administrator finds that the plan: 

(A) Does not address a startup, shutdown, or 

malfunction event that has occurred; 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-35 

(B) Fails to provide for the operation of the 

source (including associated air 

pollution control equipment) during a 

startup, shutdown, or malfunction event 

in a manner consistent with good air 

pollution control practices for 

minimizing emissions at least to the 

levels required by all relevant 

standards; or 

(C) Does not provide adequate procedures for 

correcting malfunctioning process and/or 

air pollution control equipment as 

quickly as practicable. 

(viii) If the startup, shutdown, and malfunction plan 

fails to address or inadequately addresses an 

event that meets the characteristics of a 

malfunction but was not included in the 

startup, shutdown, and malfunction plan at the 

time the owner or operator developed the plan, 

the owner or operator shall revise the 

startup, shutdown, and malfunction plan within 

45 days after the event to include detailed 

procedures for operating and maintaining the 

source during similar malfunction events and a 

program of corrective action for similar 

malfunctions of process or air pollution 

control equipment. 

(f) Compliance with nonopacity emission standards— 

(1) Applicability. The nonopacity emission standards set 

forth in this part shall apply at all times except 

during periods of startup, shutdown, and malfunction, 

and as otherwise specified in an applicable subpart. 

(2) Methods for determining compliance. 

(i) The Administrator will determine compliance 

with nonopacity emission standards in this 

part based on the results of performance tests 

conducted according to the procedures in Sec. 

63.7, unless otherwise specified in an 

applicable subpart of this part. 

(ii) The Administrator will determine compliance 

with nonopacity emission standards in this

requirements, including the evaluation of 

monitoring data, as specified in Sec. 63.6(e) 

and applicable subparts of this part. 

(iii) If an affected source conducts performance 

testing at startup to obtain an operating 

permit in the State in which the source is 

located, the results of such testing may be 

used to demonstrate compliance with a relevant 

standard if-- 

(A) The performance test was conducted within 

a reasonable amount of time before an 

initial performance test is required to 

be conducted under the relevant standard; 

(B) The performance test was conducted under 

representative operating conditions for 

the source; 

(C) The performance test was conducted and 

the resulting data were reduced using 

EPA-approved test methods and procedures, 

as specified in Sec. 63.7(e) of this 

subpart; and 

(D) The performance test was appropriately 

quality-assured, as specified in Sec. 

63.7(c) of this subpart. 

(iv) The Administrator will determine compliance 

with design, equipment, work practice, or 

operational emission standards in this part by 

review of records, inspection of the source, 

and other procedures specified in applicable 

subparts of this part. 

(v) The Administrator will determine compliance 

with design, equipment, work practice, or 

operational emission standards in this part by 

evaluation of an owner or operator’s 

conformance with operation and maintenance 

requirements, as specified in paragraph (e) of 

this section and applicable subparts of this 

part. 

(3) Finding of compliance. The Administrator will make a 

finding concerning an affected source’s compliance 

with a nonopacity emission standard, as specified in 

paragraphs (f)(1) and (f)(2) of this section, upon 
CAAPP PERMIT

obtaining all the compliance information required by 

the relevant standard (including the written reports 

of performance test results, monitoring results, and 

other information, if applicable) and any information 

available to the Administrator needed to determine 

whether proper operation and maintenance practices 

are being used. 

(g) Use of an alternative nonopacity emission standard. 

(1) If, in the Administrator’s judgment, an owner or 

operator of an affected source has established that 

an alternative means of emission limitation will 

achieve a reduction in emissions of a hazardous air 

pollutant from an affected source at least equivalent 

to the reduction in emissions of that pollutant from 

that source achieved under any design, equipment, 

work practice, or operational emission standard, or 

combination thereof, established under this part 

pursuant to section 112(h) of the Act, the 

Administrator will publish in the Federal Register a 

notice permitting the use of the alternative emission 

standard for purposes of compliance with the 

promulgated standard. Any Federal Register notice 

under this paragraph shall be published only after 

the public is notified and given the opportunity to 

comment. Such notice will restrict the permission to 

the stationary source(s) or category(ies) of sources 

from which the alternative emission standard will 

achieve equivalent emission reductions. The 

Administrator will condition permission in such 

notice on requirements to assure the proper operation 

and maintenance of equipment and practices required 

for compliance with the alternative emission standard 

and other requirements, including appropriate quality 

assurance and quality control requirements, that are 

deemed necessary. 

(2) An owner or operator requesting permission under this 

paragraph shall, unless otherwise specified in an 

applicable subpart, submit a proposed test plan or 

the results of testing and monitoring in accordance 

with Sec. 63.7 and Sec. 63.8, a description of the 

procedures followed in testing or monitoring, and a 

description of pertinent conditions during testing or 

monitoring. Any testing or monitoring conducted to 

request permission to use an alternative nonopacity 

emission standard shall be appropriately quality 

assured and quality controlled, as specified in Sec. 

63.7 and Sec. 63.8.

(3) The Administrator may establish general procedures in 

an applicable subpart that accomplish the 

requirements of paragraphs (g)(1) and (g)(2) of this 

section. 

(h) Compliance with opacity and visible emission standards— 

(1) Applicability. The opacity and visible emission 

standards set forth in this part shall apply at all 

times except during periods of startup, shutdown, and 

malfunction, and as otherwise specified in an 

applicable subpart. 

(2) Methods for determining compliance. 

(i) The Administrator will determine compliance 

with opacity and visible emission standards in 

this part based on the results of the test 

method specified in an applicable subpart. 

Whenever a continuous opacity monitoring 

system (COMS) is required to be installed to 

determine compliance with numerical opacity 

emission standards in this part, compliance 

with opacity emission standards in this part 

shall be determined by using the results from 

the COMS. Whenever an opacity emission test 

method is not specified, compliance with 

opacity emission standards in this part shall 

be determined by conducting observations in 

accordance with Test Method 9 in appendix A of 

part 60 of this chapter or the method 

specified in paragraph (h)(7)(ii) of this 

section. Whenever a visible emission test 

method is not specified, compliance with 

visible emission standards in this part shall 

be determined by conducting observations in 

accordance with Test Method 22 in appendix A 

of part 60 of this chapter. 

(ii) [Reserved] 

(iii) If an affected source undergoes opacity or 

visible emission testing at startup to obtain 

an operating permit in the State in which the 

source is located, the results of such testing 

may be used to demonstrate compliance with a 

relevant standard if-- 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-39 

(A) The opacity or visible emission test was 

conducted within a reasonable amount of 

time before a performance test is 

required to be conducted under the 

relevant standard; 

(B) The opacity or visible emission test was 

conducted under representative operating 

conditions for the source; 

(C) The opacity or visible emission test was 

conducted and the resulting data were 

reduced using EPA-approved test methods 

and procedures, as specified in Sec. 

63.7(e) of this subpart; and 

(D) The opacity or visible emission test was 

appropriately quality-assured, as 

specified in Sec. 63.7(c) of this 

section. 

(3) [Reserved] 

(4) Notification of opacity or visible emission 

observations. The owner or operator of an affected 

source shall notify the Administrator in writing of 

the anticipated date for conducting opacity or 

visible emission observations in accordance with Sec. 

63.9(f), if such observations are required for the 

source by a relevant standard. 

(5) Conduct of opacity or visible emission observations. 

When a relevant standard under this part includes an 

opacity or visible emission standard, the owner or 

operator of an affected source shall comply with the 

following: 

(i) For the purpose of demonstrating initial 

compliance, opacity or visible emission 

observations shall be conducted concurrently 

with the initial performance test required in 

Sec. 63.7 unless one of the following 

conditions applies: 

(A) If no performance test under Sec. 63.7 is 

required, opacity or visible emission 

observations shall be conducted within 60 

days after achieving the maximum 

production rate at which a new or 

reconstructed source will be operated, 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-40 

but not later than 120 days after initial 

startup of the source, or within 120 days 

after the effective date of the relevant 

standard in the case of new sources that 

start up before the standard’s effective 

date. If no performance test under Sec. 

63.7 is required, opacity or visible 

emission observations shall be conducted 

within 120 days after the compliance date 

for an existing or modified source; or 

(B) If visibility or other conditions prevent 

the opacity or visible emission 

observations from being conducted 

concurrently with the initial performance 

test required under Sec. 63.7, or within 

the time period specified in paragraph 

(h)(5)(i)(A) of this section, the 

source’s owner or operator shall 

reschedule the opacity or visible 

emission observations as soon after the 

initial performance test, or time period, 

as possible, but not later than 30 days 

thereafter, and shall advise the 

Administrator of the rescheduled date. 

The rescheduled opacity or visible 

emission observations shall be conducted 

(to the extent possible) under the same 

operating conditions that existed during 

the initial performance test conducted 

under Sec. 63.7. The visible emissions 

observer shall determine whether 

visibility or other conditions prevent 

the opacity or visible emission 

observations from being made concurrently 

with the initial performance test in 

accordance with procedures contained in 

Test Method 9 or Test Method 22 in 

appendix A of part 60 of this chapter. 

(ii) For the purpose of demonstrating initial 

compliance, the minimum total time of opacity 

observations shall be 3 hours (30 6-minute 

averages) for the performance test or other 

required set of observations (e.g., for 

fugitive-type emission sources subject only to 

an opacity emission standard). 

(iii) The owner or operator of an affected source to 

which an opacity or visible emission standard 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-41 

in this part applies shall conduct opacity or 

visible emission observations in accordance 

with the provisions of this section, record 

the results of the evaluation of emissions, 

and report to the Administrator the opacity or 

visible emission results in accordance with 

the provisions of Sec. 63.10(d). 

(iv) [Reserved] 

(v) Opacity readings of portions of plumes that 

contain condensed, uncombined water vapor 

shall not be used for purposes of determining 

compliance with opacity emission standards. 

(6) Availability of records. The owner or operator of an 

affected source shall make available, upon request by 

the Administrator, such records that the 

Administrator deems necessary to determine the 

conditions under which the visual observations were 

made and shall provide evidence indicating proof of 

current visible observer emission certification. 

(7) Use of a continuous opacity monitoring system. 

(i) The owner or operator of an affected source 

required to use a continuous opacity 

monitoring system (COMS) shall record the 

monitoring data produced during a performance 

test required under Sec. 63.7 and shall 

furnish the Administrator a written report of 

the monitoring results in accordance with the 

provisions of Sec. 63.10(e)(4). 

(ii) Whenever an opacity emission test method has 

not been specified in an applicable subpart, 

or an owner or operator of an affected source 

is required to conduct Test Method 9 

observations (see appendix A of part 60 of 

this chapter), the owner or operator may 

submit, for compliance purposes, COMS data 

results produced during any performance test 

required under Sec. 63.7 in lieu of Method 9 

data. If the owner or operator elects to 

submit COMS data for compliance with the 

opacity emission standard, he or she shall 

notify the Administrator of that decision, in 

writing, simultaneously with the notification 

under Sec. 63.7(b) of the date the performance 

test is scheduled to begin. Once the owner or 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-42 

operator of an affected source has notified 

the Administrator to that effect, the COMS 

data results will be used to determine opacity 

compliance during subsequent performance tests 

required under Sec. 63.7, unless the owner or 

operator notifies the Administrator in writing 

to the contrary not later than with the 

notification under Sec. 63.7(b) of the date 

the subsequent performance test is scheduled 

to begin. 

(iii) For the purposes of determining compliance 

with the opacity emission standard during a 

performance test required under Sec. 63.7 

using COMS data, the COMS data shall be 

reduced to 6-minute averages over the duration 

of the mass emission performance test. 

(iv) The owner or operator of an affected source 

using a COMS for compliance purposes is 

responsible for demonstrating that he/she has 

complied with the performance evaluation 

requirements of Sec. 63.8(e), that the COMS 

has been properly maintained, operated, and 

data quality-assured, as specified in Sec. 

63.8(c) and Sec. 63.8(d), and that the 

resulting data have not been altered in any 

way. 

(v) Except as provided in paragraph (h)(7)(ii) of 

this section, the results of continuous 

monitoring by a COMS that indicate that the 

opacity at the time visual observations were 

made was not in excess of the emission 

standard are probative but not conclusive 

evidence of the actual opacity of an emission, 

provided that the affected source proves that, 

at the time of the alleged violation, the 

instrument used was properly maintained, as 

specified in Sec. 63.8(c), and met Performance 

Specification 1 in appendix B of part 60 of 

this chapter, and that the resulting data have 

not been altered in any way. 

(8) Finding of compliance. The Administrator will make a 

finding concerning an affected source’s compliance 

with an opacity or visible emission standard upon 

obtaining all the compliance information required by 

the relevant standard (including the written reports 

of the results of the performance tests required by 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-43 

Sec. 63.7, the results of Test Method 9 or another 

required opacity or visible emission test method, the 

observer certification required by paragraph (h)(6) 

of this section, and the continuous opacity 

monitoring system results, whichever is/are 

applicable) and any information available to the 

Administrator needed to determine whether proper 

operation and maintenance practices are being used. 

(9) Adjustment to an opacity emission standard. 

(i) If the Administrator finds under paragraph 

(h)(8) of this section that an affected source 

is in compliance with all relevant standards 

for which initial performance tests were 

conducted under Sec. 63.7, but during the time 

such performance tests were conducted fails to 

meet any relevant opacity emission standard, 

the owner or operator of such source may 

petition the Administrator to make appropriate 

adjustment to the opacity emission standard 

for the affected source. Until the 

Administrator notifies the owner or operator 

of the appropriate adjustment, the relevant 

opacity emission standard remains applicable. 

(ii) The Administrator may grant such a petition 

upon a demonstration by the owner or operator 

that-- 

(A) The affected source and its associated 

air pollution control equipment were 

operated and maintained in a manner to 

minimize the opacity of emissions during 

the performance tests; 

(B) The performance tests were performed 

under the conditions established by the 

Administrator; and 

(C) The affected source and its associated 

air pollution control equipment were 

incapable of being adjusted or operated 

to meet the relevant opacity emission 

standard. 

(iii) The Administrator will establish an adjusted 

opacity emission standard for the affected 

source meeting the above requirements at a 

level at which the source will be able, as 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-44 

indicated by the performance and opacity 

tests, to meet the opacity emission standard 

at all times during which the source is 

meeting the mass or concentration emission 

standard. The Administrator will promulgate 

the new opacity emission standard in the 

Federal Register. 

(iv) After the Administrator promulgates an 

adjusted opacity emission standard for an 

affected source, the owner or operator of such 

source shall be subject to the new opacity 

emission standard, and the new opacity 

emission standard shall apply to such source 

during any subsequent performance tests. 

(i) Extension of compliance with emission standards. 

(1) Until an extension of compliance has been granted by 

the Administrator (or a State with an approved permit 

program) under this paragraph, the owner or operator 

of an affected source subject to the requirements of 

this section shall comply with all applicable 

requirements of this part. 

(2) Extension of compliance for early reductions and 

other reductions— 

(i) Early reductions. Pursuant to section 

112(i)(5) of the Act, if the owner or operator 

of an existing source demonstrates that the 

source has achieved a reduction in emissions 

of hazardous air pollutants in accordance with 

the provisions of subpart D of this part, the 

Administrator (or the State with an approved 

permit program) will grant the owner or 

operator an extension of compliance with 

specific requirements of this part, as 

specified in subpart D. 

(ii) Other reductions. Pursuant to section 

112(i)(6) of the Act, if the owner or operator 

of an existing source has installed best 

available control technology (BACT) (as 

defined in section 169(3) of the Act) or 

technology required to meet a lowest 

achievable emission rate (LAER) (as defined in 

section 171 of the Act) prior to the 

promulgation of an emission standard in this 

part applicable to such source and the same 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-45 

pollutant (or stream of pollutants) controlled 

pursuant to the BACT or LAER installation, the 

Administrator will grant the owner or operator 

an extension of compliance with such emission 

standard that will apply until the date 5 

years after the date on which such 

installation was achieved, as determined by 

the Administrator. 

(3) Request for extension of compliance. Paragraphs 

(i)(4) through (i)(7) of this section concern 

requests for an extension of compliance with a 

relevant standard under this part (except requests 

for an extension of compliance under paragraph 

(i)(2)(i) of this section will be handled through 

procedures specified in subpart D of this part). 

(4) (i) (A) The owner or operator of an existing 

source who is unable to comply with a 

relevant standard established under this 

part pursuant to section 112(d) of the 

Act may request that the Administrator 

(or a State, when the State has an 

approved part 70 permit program and the 

source is required to obtain a part 70 

permit under that program, or a State, 

when the State has been delegated the 

authority to implement and enforce the 

emission standard for that source) grant 

an extension allowing the source up to 1 

additional year to comply with the 

standard, if such additional period is 

necessary for the installation of 

controls. An additional extension of up 

to 3 years may be added for mining waste 

operations, if the 1-year extension of 

compliance is insufficient to dry and 

cover mining waste in order to reduce 

emissions of any hazardous air pollutant. 

The owner or operator of an affected 

source who has requested an extension of 

compliance under this paragraph and who 

is otherwise required to obtain a title V 

permit shall apply for such permit or 

apply to have the source’s title V permit 

revised to incorporate the conditions of 

the extension of compliance. The 

conditions of an extension of compliance 

granted under this paragraph will be 

incorporated into the affected source’s 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-46 

title V permit according to the 

provisions of part 70 or Federal title V 

regulations in this chapter (42 U.S.C. 

7661), whichever are applicable. 

(B) Any request under this paragraph for an 

extension of compliance with a relevant 

standard shall be submitted in writing to 

the appropriate authority not later than 

12 months before the affected source’s 

compliance date (as specified in 

paragraphs (b) and (c) of this section) 

for sources that are not including 

emission points in an emissions average, 

or not later than 18 months before the 

affected source’s compliance date (as 

specified in paragraphs (b) and (c) of 

this section) for sources that are 

including emission points in an emissions 

average. Emission standards established 

under this part may specify alternative 

dates for the submittal of requests for 

an extension of compliance if 

alternatives are appropriate for the 

source categories affected by those 

standards, e.g., a compliance date 

specified by the standard is less than 12 

(or 18) months after the standard’s 

effective date. 

(ii) The owner or operator of an existing source 

unable to comply with a relevant standard 

established under this part pursuant to 

section 112(f) of the Act may request that the 

Administrator grant an extension allowing the 

source up to 2 years after the standard’s 

effective date to comply with the standard. 

The Administrator may grant such an extension 

if he/she finds that such additional period is 

necessary for the installation of controls and 

that steps will be taken during the period of 

the extension to assure that the health of 

persons will be protected from imminent 

endangerment. Any request for an extension of 

compliance with a relevant standard under this 

paragraph shall be submitted in writing to the 

Administrator not later than 15 calendar days 

after the effective date of the relevant 

standard.

(5) The owner or operator of an existing source that has 

installed BACT or technology required to meet LAER 

[as specified in paragraph (i)(2)(ii) of this 

section] prior to the promulgation of a relevant 

emission standard in this part may request that the 

Administrator grant an extension allowing the source 

5 years from the date on which such installation was 

achieved, as determined by the Administrator, to 

comply with the standard. Any request for an 

extension of compliance with a relevant standard 

under this paragraph shall be submitted in writing to 

the Administrator not later than 120 days after the 

promulgation date of the standard. The Administrator 

may grant such an extension if he or she finds that 

the installation of BACT or technology to meet LAER 

controls the same pollutant (or stream of pollutants) 

that would be controlled at that source by the 

relevant emission standard. 

(6) (i) The request for a compliance extension under 

paragraph (i)(4) of this section shall include 

the following information: 

(A) A description of the controls to be 

installed to comply with the standard;

of emission control and process 

equipment; and 

(D) Whether the owner or operator is also 

requesting an extension of other 

applicable requirements (e.g., 

performance testing requirements). 

(ii) The request for a compliance extension under 

paragraph (i)(5) of this section shall include 

all information needed to demonstrate to the 

Administrator’s satisfaction that the 

installation of BACT or technology to meet 

LAER controls the same pollutant (or stream of 

pollutants) that would be controlled at that 

source by the relevant emission standard. 

(7) Advice on requesting an extension of compliance may 

be obtained from the Administrator (or the State with 

an approved permit program). 

(8) Approval of request for extension of compliance. 

Paragraphs (i)(9) through (i)(14) of this section 

concern approval of an extension of compliance 

requested under paragraphs (i)(4) through (i)(6) of 

this section. 

(9) Based on the information provided in any request made 

under paragraphs (i)(4) through (i)(6) of this 

section, or other information, the Administrator (or 

the State with an approved permit program) may grant 

an extension of compliance with an emission standard, 

as specified in paragraphs (i)(4) and (i)(5) of this

period; or 

(B) Under paragraph (i)(5), specify any 

additional conditions that the 

Administrator deems necessary to assure 

the proper operation and maintenance of 

the installed controls during the 

extension period. 

(11) The owner or operator of an existing source that has 

been granted an extension of compliance under 

paragraph (i)(10) of this section may be required to 

submit to the Administrator (or the State with an 

approved permit program) progress reports indicating 

whether the steps toward compliance outlined in the 

compliance schedule have been reached. The contents 

of the progress reports and the dates by which they 

shall be submitted will be specified in the written 

extension of compliance granted under paragraph 

(i)(10) of this section. 

(12) (i) The Administrator (or the State with an 

approved permit program) will notify the owner

operator to present in writing, within 15 

calendar days after he/she is notified of 

the intended denial, additional 

information or arguments to the 

Administrator before further action on 

the request. 

(iv) A final determination to deny any request for 

an extension will be in writing and will set 

forth the specific grounds on which the denial 

is based. The final determination will be 

made within 30 calendar days after 

presentation of additional information or 

argument (if the application is complete), or 

within 30 calendar days after the final date

specified for the presentation if no 

presentation is made. 

(14) The Administrator (or the State with an approved 

permit program) may terminate an extension of 

compliance at an earlier date than specified if any 

specification under paragraphs (i)(10)(iii) or 

(i)(10)(iv) of this section is not met. 

15) [Reserved] 

16) The granting of an extension under this section shall 

not abrogate the Administrator’s authority under 

section 114 of the Act. 

(j) Exemption from compliance with emission standards. The 

President may exempt any stationary source from compliance 

with any relevant standard established pursuant to section 

112 of the Act for a period of not more than 2 years if 

the President determines that the technology to implement 

such standard is not available and that it is in the 

national security interests of the United States to do so. 

An exemption under this paragraph may be extended for 1 or 

more additional periods, each period not to exceed 2 

years. 

Sec. 63.7 Performance testing requirements. 

(a) Applicability and performance test dates. 

(1) Unless otherwise specified, this section applies to 

the owner or operator of an affected source required 

to do performance testing, or another form of 

compliance demonstration, under a relevant standard. 

(2) If required to do performance testing by a relevant 

standard, and unless a waiver of performance testing 

is obtained under this section or the conditions of 

paragraph (c)(3)(ii)(B) of this section apply, the 

owner or operator of the affected source shall 

perform such tests as follows-- 

(i) Within 180 days after the effective date of a 

relevant standard for a new source that has an 

initial startup date before the effective 

date; or 

(ii) Within 180 days after initial startup for a 

new source that has an initial startup date 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-53 

after the effective date of a relevant 

standard; or 

(iii) Within 180 days after the compliance date 

specified in an applicable subpart of this 

part for an existing source subject to an 

emission standard established pursuant to 

section 112(d) of the Act, or within 180 days 

after startup of an existing source if the 

source begins operation after the effective 

date of the relevant emission standard; or 

(iv) Within 180 days after the compliance date for 

an existing source subject to an emission 

standard established pursuant to section 

112(f) of the Act; or 

(v) Within 180 days after the termination date of 

the source’s extension of compliance for an 

existing source that obtains an extension of 

compliance under Sec. 63.6(i); or 

(vi) Within 180 days after the compliance date for 

a new source, subject to an emission standard 

established pursuant to section 112(f) of the 

Act, for which construction or reconstruction 

is commenced after the proposal date of a 

relevant standard established pursuant to 

section 112(d) of the Act but before the 

proposal date of the relevant standard 

established pursuant to section 112(f) [see 

Sec. 63.6(b)(4)]; or 

(vii) [Reserved]; or 

(viii) [Reserved]; or 

(ix) When an emission standard promulgated under 

this part is more stringent than the standard 

proposed (see Sec. 63.6(b)(3)), the owner or 

operator of a new or reconstructed source 

subject to that standard for which 

construction or reconstruction is commenced 

between the proposal and promulgation dates of 

the standard shall comply with performance 

testing requirements within 180 days after the 

standard’s effective date, or within 180 days 

after startup of the source, whichever is 

later. If the promulgated standard is more 

stringent than the proposed standard, the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-54 

owner or operator may choose to demonstrate 

compliance with either the proposed or the 

promulgated standard. If the owner or 

operator chooses to comply with the proposed 

standard initially, the owner or operator 

shall conduct a second performance test within 

3 years and 180 days after the effective date 

of the standard, or after startup of the 

source, whichever is later, to demonstrate 

compliance with the promulgated standard. 

(3) The Administrator may require an owner or operator to 

conduct performance tests at the affected source at 

any other time when the action is authorized by 

section 114 of the Act. 

(b) Notification of performance test. 

(1) The owner or operator of an affected source shall 

notify the Administrator in writing of his or her 

intention to conduct a performance test at least 60 

calendar days before the performance test is 

scheduled to begin to allow the Administrator, upon 

request, to review and approve the site-specific test 

plan required under paragraph (c) of this section and 

to have an observer present during the test. 

Observation of the performance test by the 

Administrator is optional. 

(2) In the event the owner or operator is unable to 

conduct the performance test on the date specified in 

the notification requirement specified in paragraph 

(b)(1) of this section, due to unforeseeable 

circumstances beyond his or her control, the owner or 

operator shall notify the Administrator within 5 days 

prior to the scheduled performance test date and 

specify the date when the performance test is 

rescheduled. This notification of delay in 

conducting the performance test shall not relieve the 

owner or operator of legal responsibility for 

compliance with any other applicable provisions of 

this part or with any other applicable Federal, 

State, or local requirement, nor will it prevent the 

Administrator from implementing or enforcing this 

part or taking any other action under the Act. 

(c) Quality assurance program. 

(1) The results of the quality assurance program required 

in this paragraph will be considered by the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-55 

Administrator when he/she determines the validity of 

a performance test. 

(2) (i) Submission of site-specific test plan. Before 

conducting a required performance test, the 

owner or operator of an affected source shall 

develop and, if requested by the 

Administrator, shall submit a site-specific 

test plan to the Administrator for approval. 

The test plan shall include a test program 

summary, the test schedule, data quality 

objectives, and both an internal and external 

quality assurance (QA) program. Data quality 

objectives are the pretest expectations of 

precision, accuracy, and completeness of data. 

(ii) The internal QA program shall include, at a 

minimum, the activities planned by routine 

operators and analysts to provide an 

assessment of test data precision; an example 

of internal QA is the sampling and analysis of 

replicate samples. 

(iii) The external QA program shall include, at a 

minimum, application of plans for a test 

method performance audit (PA) during the 

performance test. The PA’s consist of blind 

audit samples provided by the Administrator 

and analyzed during the performance test in 

order to provide a measure of test data bias. 

The external QA program may also include 

systems audits that include the opportunity 

for on-site evaluation by the Administrator of 

instrument calibration, data validation, 

sample logging, and documentation of quality 

control data and field maintenance activities. 

(iv) The owner or operator of an affected source 

shall submit the site-specific test plan to 

the Administrator upon the Administrator’s 

request at least 60 calendar days before the 

performance test is scheduled to take place, 

that is, simultaneously with the notification 

of intention to conduct a performance test 

required under paragraph (b) of this section, 

or on a mutually agreed upon date. 

(v) The Administrator may request additional 

relevant information after the submittal of a 

site-specific test plan. 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-56 

(3) Approval of site-specific test plan. 

(i) The Administrator will notify the owner or 

operator of approval or intention to deny 

approval of the site-specific test plan (if 

review of the site-specific test plan is 

requested) within 30 calendar days after 

receipt of the original plan and within 30 

calendar days after receipt of any 

supplementary information that is submitted 

under paragraph (c)(3)(i)(B) of this section. 

Before disapproving any site-specific test 

plan, the Administrator will notify the 

applicant of the Administrator’s intention to 

disapprove the plan together with-- 

(A) Notice of the information and findings on 

which the intended disapproval is based; 

and 

(B) Notice of opportunity for the owner or 

operator to present, within 30 calendar 

days after he/she is notified of the 

intended disapproval, additional 

information to the Administrator before 

final action on the plan. 

(ii) In the event that the Administrator fails to 

approve or disapprove the site-specific test 

plan within the time period specified in 

paragraph (c)(3)(i) of this section, the 

following conditions shall apply: 

(A) If the owner or operator intends to 

demonstrate compliance using the test 

method(s) specified in the relevant 

standard, the owner or operator shall 

conduct the performance test within the 

time specified in this section using the 

specified method(s); 

(B) If the owner or operator intends to 

demonstrate compliance by using an 

alternative to any test method specified 

in the relevant standard, the owner or 

operator shall refrain from conducting 

the performance test until the 

Administrator approves the use of the 

alternative method when the Administrator 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-57 

approves the site-specific test plan (if 

review of the site-specific test plan is 

requested) or until after the alternative 

method is approved (see paragraph (f) of 

this section). If the Administrator does 

not approve the site-specific test plan 

(if review is requested) or the use of 

the alternative method within 30 days 

before the test is scheduled to begin, 

the performance test dates specified in 

paragraph (a) of this section may be 

extended such that the owner or operator 

shall conduct the performance test within 

60 calendar days after the Administrator 

approves the site-specific test plan or 

after use of the alternative method is 

approved. Notwithstanding the 

requirements in the preceding two 

sentences, the owner or operator may 

proceed to conduct the performance test 

as required in this section (without the 

Administrator’s prior approval of the 

site-specific test plan) if he/she 

subsequently chooses to use the specified 

testing and monitoring methods instead of 

an alternative. 

(iii) Neither the submission of a site-specific test 

plan for approval, nor the Administrator’s 

approval or disapproval of a plan, nor the 

Administrator’s failure to approve or 

disapprove a plan in a timely manner shall-- 

(A) Relieve an owner or operator of legal 

responsibility for compliance with any 

applicable provisions of this part or 

with any other applicable Federal, State, 

or local requirement; or 

(B) Prevent the Administrator from 

implementing or enforcing this part or 

taking any other action under the Act. 

(4) (i) Performance test method audit program. The 

owner or operator shall analyze performance 

audit (PA) samples during each performance 

test. The owner or operator shall request 

performance audit materials 45 days prior to 

the test date. Cylinder audit gases, if 

available, must be obtained from the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-58 

appropriate EPA Regional Office or from the 

responsible enforcement authority and analyzed 

in conjunction with the field samples. 

(ii) The Administrator will have sole discretion to 

require any subsequent remedial actions of the 

owner or operator based on the PA results. 

(iii) If the Administrator fails to provide required 

PA materials to an owner or operator of an 

affected source in time to analyze the PA 

samples during a performance test, the 

requirement to conduct a PA under this 

paragraph shall be waived for such source for 

that performance test. Waiver under this 

paragraph of the requirement to conduct a PA 

for a particular performance test does not 

constitute a waiver of the requirement to 

conduct a PA for future required performance 

tests. 

(d) Performance testing facilities. If required to do 

performance testing, the owner or operator of each new 

source and, at the request of the Administrator, the owner 

or operator of each existing source, shall provide 

performance testing facilities as follows: 

(1) Sampling ports adequate for test methods applicable 

to such source. This includes: 

(i) Constructing the air pollution control system 

such that volumetric flow rates and pollutant 

emission rates can be accurately determined by 

applicable test methods and procedures; and 

(ii) Providing a stack or duct free of cyclonic 

flow during performance tests, as demonstrated 

by applicable test methods and procedures; 

(2) Safe sampling platform(s); 

(3) Safe access to sampling platform(s); 

(4) Utilities for sampling and testing equipment; and 

(5) Any other facilities that the Administrator deems 

necessary for safe and adequate testing of a source.

I.D. Number: 115015AAE 

Application No.: 96030038 

9-59 

(e) Conduct of performance tests. 

(1) Performance tests shall be conducted under such 

conditions as the Administrator specifies to the 

owner or operator based on representative performance 

(i.e., performance based on normal operating 

conditions) of the affected source. Operations 

during periods of startup, shutdown, and malfunction 

shall not constitute representative conditions for 

the purpose of a performance test, nor shall 

emissions in excess of the level of the relevant 

standard during periods of startup, shutdown, and 

malfunction be considered a violation of the relevant 

standard unless otherwise specified in the relevant 

standard or a determination of noncompliance is made 

under Sec. 63.6(e). Upon request, the owner or 

operator shall make available to the Administrator 

such records as may be necessary to determine the 

conditions of performance tests. 

(2) Performance tests shall be conducted and data shall 

be reduced in accordance with the test methods and 

procedures set forth in this section, in each 

relevant standard, and, if required, in applicable 

appendices of parts 51, 60, 61, and 63 of this 

chapter unless the Administrator-- 

(i) Specifies or approves, in specific cases, the 

use of a test method with minor changes in 

methodology; or 

(ii) Approves the use of an alternative test 

method, the results of which the Administrator 

has determined to be adequate for indicating 

whether a specific affected source is in 

compliance; or 

(iii) Approves shorter sampling times and smaller 

sample volumes when necessitated by process 

variables or other factors; or 

(iv) Waives the requirement for performance tests 

because the owner or operator of an affected 

source has demonstrated by other means to the 

Administrator’s satisfaction that the affected 

source is in compliance with the relevant 

standard. 

(3) Unless otherwise specified in a relevant standard or 

test method, each performance test shall consist of 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-60 

three separate runs using the applicable test method. 

Each run shall be conducted for the time and under 

the conditions specified in the relevant standard. 

For the purpose of determining compliance with a 

relevant standard, the arithmetic mean of the results 

of the three runs shall apply. Upon receiving 

approval from the Administrator, results of a test 

run may be replaced with results of an additional 

test run in the event that-- 

(i) A sample is accidentally lost after the 

testing team leaves the site; or 

(ii) Conditions occur in which one of the three 

runs must be discontinued because of forced 

shutdown; or 

(iii) Extreme meteorological conditions occur; or 

(iv) Other circumstances occur that are beyond the 

owner or operator’s control. 

(4) Nothing in paragraphs (e)(1) through (e)(3) of this 

section shall be construed to abrogate the 

Administrator’s authority to require testing under 

section 114 of the Act. 

(f) Use of an alternative test method – 

(1) General. Until permission to use an alternative test 

method has been granted by the Administrator under 

this paragraph, the owner or operator of an affected 

source remains subject to the requirements of this 

section and the relevant standard. 

(2) The owner or operator of an affected source required 

to do performance testing by a relevant standard may 

use an alternative test method from that specified in 

the standard provided that the owner or operator-- 

(i) Notifies the Administrator of his or her 

intention to use an alternative test method 

not later than with the submittal of the sitespecific test plan (if requested by the 

Administrator) or at least 60 days before the 

performance test is scheduled to begin if a 

site-specific test plan is not submitted; 

(ii) Uses Method 301 in appendix A of this part to 

validate the alternative test method; and 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-61 

(iii) Submits the results of the Method 301 

validation process along with the notification 

of intention and the justification for not 

using the specified test method. The owner or 

operator may submit the information required 

in this paragraph well in advance of the 

deadline specified in paragraph (f)(2)(i) of 

this section to ensure a timely review by the 

Administrator in order to meet the performance 

test date specified in this section or the 

relevant standard. 

(3) The Administrator will determine whether the owner or 

operator’s validation of the proposed alternative 

test method is adequate when the Administrator 

approves or disapproves the site-specific test plan 

required under paragraph (c) of this section. If the 

Administrator finds reasonable grounds to dispute the 

results obtained by the Method 301 validation 

process, the Administrator may require the use of a 

test method specified in a relevant standard. 

(4) If the Administrator finds reasonable grounds to 

dispute the results obtained by an alternative test 

method for the purposes of demonstrating compliance 

with a relevant standard, the Administrator may 

require the use of a test method specified in a 

relevant standard. 

(5) If the owner or operator uses an alternative test 

method for an affected source during a required 

performance test, the owner or operator of such 

source shall continue to use the alternative test 

method for subsequent performance tests at that 

affected source until he or she receives approval 

from the Administrator to use another test method as 

allowed under Sec. 63.7(f). 

(6) Neither the validation and approval process nor the 

failure to validate an alternative test method shall 

abrogate the owner or operator’s responsibility to 

comply with the requirements of this part. 

(g) Data analysis, recordkeeping, and reporting. 

(1) Unless otherwise specified in a relevant standard or 

test method, or as otherwise approved by the 

Administrator in writing, results of a performance 

test shall include the analysis of samples, 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-62 

determination of emissions, and raw data. A 

performance test is “completed” when field sample 

collection is terminated. The owner or operator of 

an affected source shall report the results of the 

performance test to the Administrator before the 

close of business on the 60th day following the 

completion of the performance test, unless specified 

otherwise in a relevant standard or as approved 

otherwise in writing by the Administrator (see Sec. 

63.9(i)). The results of the performance test shall 

be submitted as part of the notification of 

compliance status required under Sec. 63.9(h). 

Before a title V permit has been issued to the owner 

or operator of an affected source, the owner or 

operator shall send the results of the performance 

test to the Administrator. After a title V permit 

has been issued to the owner or operator of an 

affected source, the owner or operator shall send the 

results of the performance test to the appropriate 

permitting authority. 

(2) [Reserved] 

(3) For a minimum of 5 years after a performance test is 

conducted, the owner or operator shall retain and 

make available, upon request, for inspection by the 

Administrator the records or results of such 

performance test and other data needed to determine 

emissions from an affected source. 

(h) Waiver of performance tests. 

(1) Until a waiver of a performance testing requirement 

has been granted by the Administrator under this 

paragraph, the owner or operator of an affected 

source remains subject to the requirements of this 

section. 

(2) Individual performance tests may be waived upon 

written application to the Administrator if, in the 

Administrator’s judgment, the source is meeting the 

relevant standard(s) on a continuous basis, or the 

source is being operated under an extension of 

compliance, or the owner or operator has requested an 

extension of compliance and the Administrator is 

still considering that request. 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-63 

(3) Request to waive a performance test. 

(i) If a request is made for an extension of 

compliance under Sec. 63.6(i), the application 

for a waiver of an initial performance test 

shall accompany the information required for 

the request for an extension of compliance. 

If no extension of compliance is requested or 

if the owner or operator has requested an 

extension of compliance and the Administrator 

is still considering that request, the 

application for a waiver of an initial 

performance test shall be submitted at least 

60 days before the performance test if the 

site-specific test plan under paragraph (c) of 

this section is not submitted. 

(ii) If an application for a waiver of a subsequent 

performance test is made, the application may 

accompany any required compliance progress 

report, compliance status report, or excess 

emissions and continuous monitoring system 

performance report [such as those required 

under Sec. 63.6(i), Sec. 63.9(h), and Sec. 

63.10(e) or specified in a relevant standard 

or in the source’s title V permit], but it 

shall be submitted at least 60 days before the 

performance test if the site-specific test 

plan required under paragraph (c) of this 

section is not submitted. 

(iii) Any application for a waiver of a performance 

test shall include information justifying the 

owner or operator’s request for a waiver, such 

as the technical or economic infeasibility, or 

the impracticality, of the affected source 

performing the required test. 

(4) Approval of request to waive performance test. The 

Administrator will approve or deny a request for a 

waiver of a performance test made under paragraph 

(h)(3) of this section when he/she-- 

(i) Approves or denies an extension of compliance 

under Sec. 63.6(i)(8); or 

(ii) Approves or disapproves a site-specific test 

plan under Sec. 63.7(c)(3); or

(iii) Makes a determination of compliance following 

the submission of a required compliance status 

report or excess emissions and continuous 

monitoring systems performance report; or 

(iv) Makes a determination of suitable progress 

towards compliance following the submission of 

a compliance progress report, whichever is 

applicable. 

(5) Approval of any waiver granted under this section 

shall not abrogate the Administrator’s authority 

under the Act or in any way prohibit the 

Administrator from later canceling the waiver. The 

cancellation will be made only after notice is given 

to the owner or operator of the affected source. 

[59 FR 12430, Mar. 16, 1994, as amended at 65 FR 62215, Oct. 17, 2000] 

Sec. 63.8 Monitoring requirements. 

(a) Applicability. 

(1) (i) Unless otherwise specified in a relevant 

standard, this section applies to the owner or 

operator of an affected source required to do 

monitoring under that standard. 

(ii) Relevant standards established under this part 

will specify monitoring systems, methods, or 

procedures, monitoring frequency, and other 

pertinent requirements for source(s) regulated 

by those standards. This section specifies 

general monitoring requirements such as those 

governing the conduct of monitoring and 

requests to use alternative monitoring 

methods. In addition, this section specifies 

detailed requirements that apply to affected 

sources required to use continuous monitoring 

systems (CMS) under a relevant standard. 

(2) For the purposes of this part, all CMS required under 

relevant standards shall be subject to the provisions 

of this section upon promulgation of performance 

specifications for CMS as specified in the relevant 

standard or otherwise by the Administrator. 

(3) [Reserved] 
CAAPP PERMIT

Application No.: 96030038 

9-65 

(4) Additional monitoring requirements for control 

devices used to comply with provisions in relevant 

standards of this part are specified in Sec. 63.11. 

(b) Conduct of monitoring. 

(1) Monitoring shall be conducted as set forth in this 

section and the relevant standard(s) unless the 

Administrator-- 

(i) Specifies or approves the use of minor changes 

in methodology for the specified monitoring 

requirements and procedures; or 

(ii) Approves the use of alternatives to any 

monitoring requirements or procedures. 

(iii) Owners or operators with flares subject to 

Sec. 63.11(b) are not subject to the 

requirements of this section unless otherwise 

specified in the relevant standard. 

(2) (i) When the effluents from a single affected 

source, or from two or more affected sources, 

are combined before being released to the 

atmosphere, the owner or operator shall 

install an applicable CMS on each effluent. 

(ii) If the relevant standard is a mass emission 

standard and the effluent from one affected 

source is released to the atmosphere through 

more than one point, the owner or operator 

shall install an applicable CMS at each 

emission point unless the installation of 

fewer systems is-- 

(A) Approved by the Administrator; or 

(B) Provided for in a relevant standard 

(e.g., instead of requiring that a CMS be 

installed at each emission point before 

the effluents from those points are 

channeled to a common control device, the 

standard specifies that only one CMS is 

required to be installed at the vent of 

the control device). 

(3) When more than one CMS is used to measure the 

emissions from one affected source (e.g., multiple 

breechings, multiple outlets), the owner or operator 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-66 

shall report the results as required for each CMS. 

However, when one CMS is used as a backup to another 

CMS, the owner or operator shall report the results 

from the CMS used to meet the monitoring requirements 

of this part. If both such CMS are used during a 

particular reporting period to meet the monitoring 

requirements of this part, then the owner or operator 

shall report the results from each CMS for the 

relevant compliance period. 

(c) Operation and maintenance of continuous monitoring 

systems. 

(1) The owner or operator of an affected source shall 

maintain and operate each CMS as specified in this 

section, or in a relevant standard, and in a manner 

consistent with good air pollution control practices. 

(i) The owner or operator of an affected source 

shall ensure the immediate repair or 

replacement of CMS parts to correct “routine” 

or otherwise predictable CMS malfunctions as 

defined in the source’s startup, shutdown, and 

malfunction plan required by Sec. 63.6(e)(3). 

The owner or operator shall keep the necessary 

parts for routine repairs of the affected 

equipment readily available. If the plan is 

followed and the CMS repaired immediately, 

this action shall be reported in the 

semiannual startup, shutdown, and malfunction 

report required under Sec. 63.10(d)(5)(i). 

(ii) For those malfunctions or other events that affect 

the CMS and are not addressed by the startup, 

shutdown, and malfunction plan, the owner or 

operator shall report actions that are not 

consistent with the startup, shutdown, and 

malfunction plan within 24 hours after commencing 

actions inconsistent with the plan. The owner or 

operator shall send a follow-up report within 2 

weeks after commencing actions inconsistent with the 

plan that either certifies that corrections have 

been made or includes a corrective action plan and 

schedule. The owner or operator shall provide proof 

that repair parts have been ordered or any other 

records that would indicate that the delay in making 

repairs is beyond his or her control. 

(iii) The Administrator’s determination of whether 

acceptable operation and maintenance

procedures are being used will be based on 

information that may include, but is not 

limited to, review of operation and 

maintenance procedures, operation and 

maintenance records, manufacturing 

recommendations and specifications, and 

inspection of the CMS. Operation and 

maintenance procedures written by the CMS 

manufacturer and other guidance also can be 

used to maintain and operate each CMS. 

(2) All CMS shall be installed such that representative 

measurements of emissions or process parameters from 

the affected source are obtained. In addition, CEMS 

shall be located according to procedures contained in 

the applicable performance specification(s). 

(3) All CMS shall be installed, operational, and the data 

verified as specified in the relevant standard either 

prior to or in conjunction with conducting 

performance tests under Sec. 63.7. Verification of 

operational status shall, at a minimum, include 

completion of the manufacturer’s written 

specifications or recommendations for installation, 

operation, and calibration of the system. 

(4) Except for system breakdowns, out-of-control periods, 

repairs, maintenance periods, calibration checks, and 

zero (low-level) and high-level calibration drift 

adjustments, all CMS, including COMS and CEMS, shall 

be in continuous operation and shall meet minimum 

frequency of operation requirements as follows: 

(i) All COMS shall complete a minimum of one cycle 

of sampling and analyzing for each successive 

10-second period and one cycle of data 

recording for each successive 6-minute period. 

(ii) All CEMS for measuring emissions other than 

opacity shall complete a minimum of one cycle 

of operation (sampling, analyzing, and data 

recording) for each successive 15-minute 

period. 

(5) Unless otherwise approved by the Administrator, 

minimum procedures for COMS shall include a method 

for producing a simulated zero opacity condition and 

an upscale (high-level) opacity condition using a 

certified neutral density filter or other related 

technique to produce a known obscuration of the light

Application No.: 96030038 

9-68 

beam. Such procedures shall provide a system check 

of all the analyzer’s internal optical surfaces and 

all electronic circuitry, including the lamp and 

photodetector assembly normally used in the 

measurement of opacity. 

(6) The owner or operator of a CMS installed in 

accordance with the provisions of this part and the 

applicable CMS performance specification(s) shall 

check the zero (low-level) and high-level calibration 

drifts at least once daily in accordance with the 

written procedure specified in the performance 

evaluation plan developed under paragraphs (e)(3)(i) 

and (e)(3)(ii) of this section. The zero (low-level) 

and high-level calibration drifts shall be adjusted, 

at a minimum, whenever the 24-hour zero (low-level) 

drift exceeds two times the limits of the applicable 

performance specification(s) specified in the 

relevant standard. The system must allow the amount 

of excess zero (low-level) and high-level drift 

measured at the 24-hour interval checks to be 

recorded and quantified, whenever specified. For 

COMS, all optical and instrumental surfaces exposed 

to the effluent gases shall be cleaned prior to 

performing the zero (low-level) and high-level drift 

adjustments; the optical surfaces and instrumental 

surfaces shall be cleaned when the cumulative 

automatic zero compensation, if applicable, exceeds 4 

percent opacity. 

(7) (i) A CMS is out of control if-- 

(A) The zero (low-level), mid-level (if 

applicable), or high-level calibration 

drift (CD) exceeds two times the 

applicable CD specification in the 

applicable performance specification or 

in the relevant standard; or 

(B) The CMS fails a performance test audit 

(e.g., cylinder gas audit), relative 

accuracy audit, relative accuracy test 

audit, or linearity test audit; or 

(C) The COMS CD exceeds two times the limit 

in the applicable performance 

specification in the relevant standard. 

(ii) When the CMS is out of control, the owner or 

operator of the affected source shall take the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-69 

necessary corrective action and shall repeat 

all necessary tests which indicate that the 

system is out of control. The owner or 

operator shall take corrective action and 

conduct retesting until the performance 

requirements are below the applicable limits. 

The beginning of the out-of-control period is 

the hour the owner or operator conducts a 

performance check (e.g., calibration drift) 

that indicates an exceedance of the 

performance requirements established under 

this part. The end of the out-of-control 

period is the hour following the completion of 

corrective action and successful demonstration 

that the system is within the allowable 

limits. During the period the CMS is out of 

control, recorded data shall not be used in 

data averages and calculations, or to meet any 

data availability requirement established 

under this part. 

(8) The owner or operator of a CMS that is out of control 

as defined in paragraph (c)(7) of this section shall 

submit all information concerning out-of-control 

periods, including start and end dates and hours and 

descriptions of corrective actions taken, in the 

excess emissions and continuous monitoring system 

performance report required in Sec. 63.10(e)(3). 

(d) Quality control program. 

(1) The results of the quality control program required in 

this paragraph will be considered by the Administrator 

when he/she determines the validity of monitoring data. 

(2) The owner or operator of an affected source that is 

required to use a CMS and is subject to the 

monitoring requirements of this section and a 

relevant standard shall develop and implement a CMS 

quality control program. As part of the quality 

control program, the owner or operator shall develop 

and submit to the Administrator for approval upon 

request a site-specific performance evaluation test 

plan for the CMS performance evaluation required in 

paragraph (e)(3)(i) of this section, according to the 

procedures specified in paragraph (e). In addition, 

each quality control program shall include, at a 

minimum, a written protocol that describes procedures 

for each of the following operations: 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-70 

(i) Initial and any subsequent calibration of the CMS; 

(ii) Determination and adjustment of the 

calibration drift of the CMS; 

(iii) Preventive maintenance of the CMS, including 

spare parts inventory; 

(iv) Data recording, calculations, and reporting; 

(v) Accuracy audit procedures, including sampling 

and analysis methods; and 

(vi) Program of corrective action for a 

malfunctioning CMS. 

(3) The owner or operator shall keep these written 

procedures on record for the life of the affected 

source or until the affected source is no longer 

subject to the provisions of this part, to be made 

available for inspection, upon request, by the 

Administrator. If the performance evaluation plan is 

revised, the owner or operator shall keep previous 

(i.e., superseded) versions of the performance 

evaluation plan on record to be made available for 

inspection, upon request, by the Administrator, for a 

period of 5 years after each revision to the plan. 

Where relevant, e.g., program of corrective action 

for a malfunctioning CMS, these written procedures 

may be incorporated as part of the affected source’s 

startup, shutdown, and malfunction plan to avoid 

duplication of planning and recordkeeping efforts. 

(e) Performance evaluation of continuous monitoring systems— 

(1) General. When required by a relevant standard, and 

at any other time the Administrator may require under 

section 114 of the Act, the owner or operator of an 

affected source being monitored shall conduct a 

performance evaluation of the CMS. Such performance 

evaluation shall be conducted according to the 

applicable specifications and procedures described in 

this section or in the relevant standard. 

(2) Notification of performance evaluation. The owner or 

operator shall notify the Administrator in writing of 

the date of the performance evaluation simultaneously 

with the notification of the performance test date 

required under Sec. 63.7(b) or at least 60 days prior 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-71 

to the date the performance evaluation is scheduled 

to begin if no performance test is required. 

(3) (i) Submission of site-specific performance 

evaluation test plan. Before conducting a 

required CMS performance evaluation, the owner 

or operator of an affected source shall 

develop and submit a site-specific performance 

evaluation test plan to the Administrator for 

approval upon request. The performance 

evaluation test plan shall include the 

evaluation program objectives, an evaluation 

program summary, the performance evaluation 

schedule, data quality objectives, and both an 

internal and external QA program. Data 

quality objectives are the pre-evaluation 

expectations of precision, accuracy, and 

completeness of data. 

(ii) The internal QA program shall include, at a 

minimum, the activities planned by routine 

operators and analysts to provide an 

assessment of CMS performance. The external 

QA program shall include, at a minimum, 

systems audits that include the opportunity 

for on-site evaluation by the Administrator of 

instrument calibration, data validation, 

sample logging, and documentation of quality 

control data and field maintenance activities. 

(iii) The owner or operator of an affected source shall 

submit the site-specific performance evaluation 

test plan to the Administrator (if requested) at 

least 60 days before the performance test or 

performance evaluation is scheduled to begin, or 

on a mutually agreed upon date, and review and 

approval of the performance evaluation test plan 

by the Administrator will occur with the review 

and approval of the site-specific test plan (if 

review of the site-specific test plan is 

requested). 

(iv) The Administrator may request additional relevant 

information after the submittal of a site-specific 

performance evaluation test plan. 

(v) In the event that the Administrator fails to 

approve or disapprove the site-specific 

performance evaluation test plan within the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-72 

time period specified in Sec. 63.7(c)(3), the 

following conditions shall apply: 

(A) If the owner or operator intends to 

demonstrate compliance using the 

monitoring method(s) specified in the 

relevant standard, the owner or operator 

shall conduct the performance evaluation 

within the time specified in this subpart

using the specified method(s); 

(B) If the owner or operator intends to 

demonstrate compliance by using an 

alternative to a monitoring method 

specified in the relevant standard, the 

owner or operator shall refrain from 

conducting the performance evaluation 

until the Administrator approves the use 

of the alternative method. If the 

Administrator does not approve the use of 

the alternative method within 30 days 

before the performance evaluation is 

scheduled to begin, the performance 

evaluation deadlines specified in 

paragraph (e)(4) of this section may be 

extended such that the owner or operator 

shall conduct the performance evaluation 

within 60 calendar days after the 

Administrator approves the use of the 

alternative method. Notwithstanding the 

requirements in the preceding two 

sentences, the owner or operator may 

proceed to conduct the performance 

evaluation as required in this section 

(without the Administrator’s prior 

approval of the site-specific performance 

evaluation test plan) if he/she 

subsequently chooses to use the specified 

monitoring method(s) instead of an 

alternative. 

(vi) Neither the submission of a site-specific 

performance evaluation test plan for approval, 

nor the Administrator’s approval or 

disapproval of a plan, nor the Administrator’ 

failure to approve or disapprove a plan in a 

timely manner shall-- 

(A) Relieve an owner or operator of legal 

responsibility for compliance with any 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-73 

applicable provisions of this part or 

with any other applicable Federal, State, 

or local requirement; or 

(B) Prevent the Administrator from 

implementing or enforcing this part or 

taking any other action under the Act. 

(4) Conduct of performance evaluation and performance 

evaluation dates. The owner or operator of an 

affected source shall conduct a performance 

evaluation of a required CMS during any performance 

test required under Sec. 63.7 in accordance with the 

applicable performance specification as specified in 

the relevant standard. Notwithstanding the 

requirement in the previous sentence, if the owner or 

operator of an affected source elects to submit COMS 

data for compliance with a relevant opacity emission 

standard as provided under Sec. 63.6(h)(7), he/she 

shall conduct a performance evaluation of the COMS as 

specified in the relevant standard, before the 

performance test required under Sec. 63.7 is 

conducted in time to submit the results of the 

performance evaluation as specified in paragraph 

(e)(5)(ii) of this section. If a performance test is 

not required, or the requirement for a performance 

test has been waived under Sec. 63.7(h), the owner or 

operator of an affected source shall conduct the 

performance evaluation not later than 180 days after 

the appropriate compliance date for the affected 

source, as specified in Sec. 63.7(a), or as otherwise 

specified in the relevant standard. 

(5) Reporting performance evaluation results. 

(i) The owner or operator shall furnish the 

Administrator a copy of a written report of 

the results of the performance evaluation 

simultaneously with the results of the 

performance test required under Sec. 63.7 or 

within 60 days of completion of the 

performance evaluation if no test is required, 

unless otherwise specified in a relevant 

standard. The Administrator may request that 

the owner or operator submit the raw data from 

a performance evaluation in the report of the 

performance evaluation results. 

(ii) The owner or operator of an affected source 

using a COMS to determine opacity compliance 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-74 

during any performance test required under 

Sec. 63.7 and described in Sec. 63.6(d)(6) 

shall furnish the Administrator two or, upon 

request, three copies of a written report of 

the results of the COMS performance evaluation 

under this paragraph. The copies shall be 

provided at least 15 calendar days before the 

performance test required under Sec. 63.7 is 

conducted. 

(f) Use of an alternative monitoring method— 

(1) General. Until permission to use an alternative 

monitoring method has been granted by the 

Administrator under this paragraph, the owner or 

operator of an affected source remains subject to the 

requirements of this section and the relevant 

standard. 

(2) After receipt and consideration of written 

application, the Administrator may approve 

alternatives to any monitoring methods or procedures 

of this part including, but not limited to, the 

following: 

(i) Alternative monitoring requirements when 

installation of a CMS specified by a relevant 

standard would not provide accurate 

measurements due to liquid water or other 

interferences caused by substances within the 

effluent gases; 

(ii) Alternative monitoring requirements when the 

affected source is infrequently operated; 

(iii) Alternative monitoring requirements to 

accommodate CEMS that require additional 

measurements to correct for stack moisture 

conditions; 

(iv) Alternative locations for installing CMS when 

the owner or operator can demonstrate that 

installation at alternate locations will 

enable accurate and representative 

measurements; 

(v) Alternate methods for converting pollutant 

concentration measurements to units of the 

relevant standard; 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-75 

(vi) Alternate procedures for performing daily 

checks of zero (low-level) and high-level 

drift that do not involve use of high-level 

gases or test cells; 

(vii) Alternatives to the American Society for 

Testing and Materials (ASTM) test methods or 

sampling procedures specified by any relevant 

standard; 

(viii) Alternative CMS that do not meet the design or 

performance requirements in this part, but 

adequately demonstrate a definite and 

consistent relationship between their 

measurements and the measurements of opacity 

by a system complying with the requirements as 

specified in the relevant standard. The 

Administrator may require that such 

demonstration be performed for each affected 

source; or 

(ix) Alternative monitoring requirements when the 

effluent from a single affected source or the 

combined effluent from two or more affected 

sources is released to the atmosphere through 

more than one point. 

(3) If the Administrator finds reasonable grounds to 

dispute the results obtained by an alternative 

monitoring method, requirement, or procedure, the 

Administrator may require the use of a method, 

requirement, or procedure specified in this section 

or in the relevant standard. If the results of the 

specified and alternative method, requirement, or 

procedure do not agree, the results obtained by the 

specified method, requirement, or procedure shall 

prevail. 

(4) (i) Request to use alternative monitoring method. 

An owner or operator who wishes to use an 

alternative monitoring method shall submit an 

application to the Administrator as described 

in paragraph (f)(4)(ii) of this section, 

below. The application may be submitted at 

any time provided that the monitoring method 

is not used to demonstrate compliance with a 

relevant standard or other requirement. If 

the alternative monitoring method is to be 

used to demonstrate compliance with a relevant 

standard, the application shall be submitted 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-76 

not later than with the site-specific test 

plan required in Sec. 63.7(c) (if requested) 

or with the site-specific performance 

evaluation plan (if requested) or at least 60 

days before the performance evaluation is 

scheduled to begin. 

(ii) The application shall contain a description of 

the proposed alternative monitoring system and 

a performance evaluation test plan, if 

required, as specified in paragraph (e)(3) of 

this section. In addition, the application 

shall include information justifying the owner 

or operator’s request for an alternative 

monitoring method, such as the technical or 

economic infeasibility, or the impracticality, 

of the affected source using the required 

method. 

(iii) The owner or operator may submit the 

information required in this paragraph well in 

advance of the submittal dates specified in 

paragraph (f)(4)(i) above to ensure a timely 

review by the Administrator in order to meet 

the compliance demonstration date specified in 

this section or the relevant standard. 

(5) Approval of request to use alternative monitoring 

method. 

(i) The Administrator will notify the owner or 

operator of approval or intention to deny 

approval of the request to use an alternative 

monitoring method within 30 calendar days 

after receipt of the original request and 

within 30 calendar days after receipt of any 

supplementary information that is submitted. 

Before disapproving any request to use an 

alternative monitoring method, the 

Administrator will notify the applicant of the 

Administrator’s intention to disapprove the 

request together with-- 

(A) Notice of the information and findings on 

which the intended disapproval is based; 

and 

(B) Notice of opportunity for the owner or 

operator to present additional 

information to the Administrator before 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-77 

final action on the request. At the time 

the Administrator notifies the applicant 

of his or her intention to disapprove the 

request, the Administrator will specify 

how much time the owner or operator will 

have after being notified of the intended 

disapproval to submit the additional 

information. 

(ii) The Administrator may establish general 

procedures and criteria in a relevant standard 

to accomplish the requirements of paragraph 

(f)(5)(i) of this section. 

(iii) If the Administrator approves the use of an 

alternative monitoring method for an affected 

source under paragraph (f)(5)(i) of this 

section, the owner or operator of such source 

shall continue to use the alternative 

monitoring method until he or she receives 

approval from the Administrator to use another 

monitoring method as allowed by Sec. 63.8(f). 

(6) Alternative to the relative accuracy test. An 

alternative to the relative accuracy test for CEMS 

specified in a relevant standard may be requested as 

follows: 

(i) Criteria for approval of alternative 

procedures. An alternative to the test method 

for determining relative accuracy is available 

for affected sources with emission rates 

demonstrated to be less than 50 percent of the 

relevant standard. The owner or operator of 

an affected source may petition the 

Administrator under paragraph (f)(6)(ii) of 

this section to substitute the relative 

accuracy test in section 7 of Performance 

Specification 2 with the procedures in section 

10 if the results of a performance test 

conducted according to the requirements in 

Sec. 63.7, or other tests performed following 

the criteria in Sec. 63.7, demonstrate that 

the emission rate of the pollutant of interest 

in the units of the relevant standard is less 

than 50 percent of the relevant standard. For 

affected sources subject to emission 

limitations expressed as control efficiency 

levels, the owner or operator may petition the 

Administrator to substitute the relative 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-78 

accuracy test with the procedures in section 

10 of Performance Specification 2 if the 

control device exhaust emission rate is less 

than 50 percent of the level needed to meet 

the control efficiency requirement. The 

alternative procedures do not apply if the 

CEMS is used continuously to determine 

compliance with the relevant standard. 

(ii) Petition to use alternative to relative 

accuracy test. The petition to use an 

alternative to the relative accuracy test 

shall include a detailed description of the 

procedures to be applied, the location and the 

procedure for conducting the alternative, the 

concentration or response levels of the 

alternative relative accuracy materials, and 

the other equipment checks included in the 

alternative procedure(s). The Administrator 

will review the petition for completeness and 

applicability. The Administrator’s 

determination to approve an alternative will 

depend on the intended use of the CEMS data 

and may require specifications more stringent 

than in Performance Specification 2. 

(iii) Rescission of approval to use alternative to 

relative accuracy test. The Administrator 

will review the permission to use an 

alternative to the CEMS relative accuracy test 

and may rescind such permission if the CEMS 

data from a successful completion of the 

alternative relative accuracy procedure 

indicate that the affected source’s emissions 

are approaching the level of the relevant 

standard. The criterion for reviewing the 

permission is that the collection of CEMS data 

shows that emissions have exceeded 70 percent 

of the relevant standard for any averaging 

period, as specified in the relevant standard. 

For affected sources subject to emission 

limitations expressed as control efficiency 

levels, the criterion for reviewing the 

permission is that the collection of CEMS data 

shows that exhaust emissions have exceeded 70 

percent of the level needed to meet the 

control efficiency requirement for any 

averaging period, as specified in the relevant 

standard. The owner or operator of the 

affected source shall maintain records and 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-79 

determine the level of emissions relative to 

the criterion for permission to use an 

alternative for relative accuracy testing. If 

this criterion is exceeded, the owner or 

operator shall notify the Administrator within 

10 days of such occurrence and include a 

description of the nature and cause of the 

increased emissions. The Administrator will 

review the notification and may rescind 

permission to use an alternative and require 

the owner or operator to conduct a relative 

accuracy test of the CEMS as specified in 

section 7 of Performance Specification 2. 

(g) Reduction of monitoring data. 

(1) The owner or operator of each CMS shall reduce the 

monitoring data as specified in this paragraph. In 

addition, each relevant standard may contain 

additional requirements for reducing monitoring data. 

When additional requirements are specified in a 

relevant standard, the standard will identify any 

unnecessary or duplicated requirements in this 

paragraph that the owner or operator need not comply 

with. 

(2) The owner or operator of each COMS shall reduce all 

data to 6-minute averages calculated from 36 or more 

data points equally spaced over each 6-minute period. 

Data from CEMS for measurement other than opacity, 

unless otherwise specified in the relevant standard, 

shall be reduced to 1-hour averages computed from 

four or more data points equally spaced over each 1-

hour period, except during periods when calibration, 

quality assurance, or maintenance activities pursuant 

to provisions of this part are being performed. 

During these periods, a valid hourly average shall 

consist of at least two data points with each 

representing a 15-minute period. Alternatively, an 

arithmetic or integrated 1-hour average of CEMS data 

may be used. Time periods for averaging are defined 

in Sec. 63.2. 

(3) The data may be recorded in reduced or nonreduced 

form (e.g., ppm pollutant and percent O2 or ng/J of 

pollutant). 

(4) All emission data shall be converted into units of 

the relevant standard for reporting purposes using 

the conversion procedures specified in that standard. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-80 

After conversion into units of the relevant standard, 

the data may be rounded to the same number of 

significant digits as used in that standard to 

specify the emission limit (e.g., rounded to the 

nearest 1 percent opacity). 

(5) Monitoring data recorded during periods of 

unavoidable CMS breakdowns, out-of-control periods, 

repairs, maintenance periods, calibration checks, and 

zero (low-level) and high-level adjustments shall not 

be included in any data average computed under this 

part. For owners or operators complying with the 

requirements of Sec. 63.10(b)(2)(vii) (A) or (B), 

data averages must include any data recorded during 

periods of monitor breakdown or malfunction. 

[59 FR 12430, Mar. 16, 1994, as amended at 64 FR 7468, Feb. 12, 1999] 

Sec. 63.9 Notification requirements. 

(a) Applicability and general information. 

(1) The requirements in this section apply to owners and 

operators of affected sources that are subject to the 

provisions of this part, unless specified otherwise 

in a relevant standard. 

(2) For affected sources that have been granted an 

extension of compliance under subpart D of this part, 

the requirements of this section do not apply to 

those sources while they are operating under such 

compliance extensions. 

(3) If any State requires a notice that contains all the 

information required in a notification listed in this 

section, the owner or operator may send the 

Administrator a copy of the notice sent to the State 

to satisfy the requirements of this section for that 

notification. 

(4) (i) Before a State has been delegated the 

authority to implement and enforce 

notification requirements established under 

this part, the owner or operator of an 

affected source in such State subject to such 

requirements shall submit notifications to the

opacity or visible emission observations are scheduled to 

take place. 

(g) Additional notification requirements for sources with 

continuous monitoring systems. The owner or operator of 

an affected source required to use a CMS by a relevant 

standard shall furnish the Administrator written 

notification as follows: 

(1) A notification of the date the CMS performance 

evaluation under Sec. 63.8(e) is scheduled to begin, 

submitted simultaneously with the notification of the 

performance test date required under Sec. 63.7(b). If 

no performance test is required, or if the requirement 

to conduct a performance test has been waived for an 

affected source under Sec. 63.7(h), the owner or 

operator shall notify the Administrator in writing of 

the date of the performance evaluation at least 60 

calendar days before the evaluation is scheduled to 

begin; 

(2) A notification that COMS data results will be used to 

determine compliance with the applicable opacity 

emission standard during a performance test required 

by Sec. 63.7 in lieu of Method 9 or other opacity 

emissions test method data, as allowed by Sec. 

63.6(h)(7)(ii), if compliance with an opacity 

emission standard is required for the source by a 

relevant standard. The notification shall be 

submitted at least 60 calendar days before the 

performance test is scheduled to begin; and 

(3) A notification that the criterion necessary to 

continue use of an alternative to relative accuracy 

testing, as provided by Sec. 63.8(f)(6), has been 

exceeded. The notification shall be delivered or 

postmarked not later than 10 days after the 

occurrence of such exceedance, and it shall include a 

description of the nature and cause of the increased 

emissions. 

(h) Notification of compliance status. 

(1) The requirements of paragraphs (h)(2) through (h)(4) 

of this section apply when an affected source becomes

(ii) The notification shall be sent before the 

close of business on the 60th day following 

the completion of the relevant compliance 

demonstration activity specified in the 

relevant standard (unless a different 

reporting period is specified in a relevant 

standard, in which case the letter shall be 

sent before the close of business on the day 

the report of the relevant testing or 

monitoring results is required to be delivered 

or postmarked). For example, the notification 

shall be sent before close of business on the 

60th (or other required) day following 

completion of the initial performance test and 

again before the close of business on the 60th 

(or other required) day following the 

completion of any subsequent required 

performance test. If no performance test is 

required but opacity or visible emission 

observations are required to demonstrate 

compliance with an opacity or visible emission 

standard under this part, the notification of 

compliance status shall be sent before close 

of business on the 30th day following the 

completion of opacity or visible emission 

observations. 

(3) After a title V permit has been issued to the owner 

or operator of an affected source, the owner or 

operator of such source shall comply with all 

requirements for compliance status reports contained 

in the source’s title V permit, including reports

required in paragraphs (d)(1)(ii)(H) and (d)(2) of 

Sec. 63.5, the owner or operator shall submit the 

actual emissions data and other correct information 

as soon as available but no later than with the 

initial notification of compliance status required in 

this section. 

(6) Advice on a notification of compliance status may be 

obtained from the Administrator. 

(i) Adjustment to time periods or postmark 

deadlines for submittal and review of required 

communications. 

(1) (i) Until an adjustment of a time 

period or postmark deadline has 

been approved by the Administrator 

under paragraphs (i)(2) and (i)(3) 

of this section, the owner or 

operator of an affected source 

remains strictly subject to the 

requirements of this part. 

(ii) An owner or operator shall request 

the adjustment provided for in 

paragraphs (i)(2) and (i)(3) of 

this section each time he or she 

wishes to change an applicable time 

period or postmark deadline 

specified in this part. 

(2) Notwithstanding time periods or postmark 

deadlines specified in this part for the 

submittal of information to the 

Administrator by an owner or operator, or 

the review of such information by the 

Administrator, such time periods or 

deadlines may be changed by mutual 

agreement between the owner or operator 

and the Administrator. An owner or 

operator who wishes to request a change 

in a time period or postmark deadline for 

a particular requirement shall request 

the adjustment in writing as soon as 

practicable before the subject activity 

is required to take place. The owner or 

operator shall include in the request 

whatever information he or she considers 

useful to convince the Administrator that

Sec. 63.10 Recordkeeping and reporting requirements. 

(a) Applicability and general information. 

(1) The requirements of this section apply to owners or 

operators of affected sources who are subject to the 

provisions of this part, unless specified otherwise 

in a relevant standard. 

(2) For affected sources that have been granted an 

extension of compliance under subpart D of this part, 

the requirements of this section do not apply to 

those sources while they are operating under such 

compliance extensions. 

(3) If any State requires a report that contains all the 

information required in a report listed in this 

section, an owner or operator may send the 

Administrator a copy of the report sent to the State 

to satisfy the requirements of this section for that 

report. 

(4) (i) Before a State has been delegated the 

authority to implement and enforce 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-90 

recordkeeping and reporting requirements 

established under this part, the owner or 

operator of an affected source in such State 

subject to such requirements shall submit 

reports to the appropriate Regional Office of 

the EPA (to the attention of the Director of 

the Division indicated in the list of the EPA 

Regional Offices in Sec. 63.13). 

(ii) After a State has been delegated the authority 

to implement and enforce recordkeeping and 

reporting requirements established under this 

part, the owner or operator of an affected 

source in such State subject to such 

requirements shall submit reports to the 

delegated State authority (which may be the 

same as the permitting authority). In 

addition, if the delegated (permitting) 

authority is the State, the owner or operator 

shall send a copy of each report submitted to 

the State to the appropriate Regional Office 

of the EPA, as specified in paragraph 

(a)(4)(i) of this section. The Regional 

Office may waive this requirement for any 

reports at its discretion. 

(5) If an owner or operator of an affected source in a 

State with delegated authority is required to submit 

periodic reports under this part to the State, and if 

the State has an established timeline for the 

submission of periodic reports that is consistent 

with the reporting frequency(ies) specified for such 

source under this part, the owner or operator may 

change the dates by which periodic reports under this 

part shall be submitted (without changing the 

frequency of reporting) to be consistent with the 

State’s schedule by mutual agreement between the 

owner or operator and the State. For each relevant 

standard established pursuant to section 112 of the 

Act, the allowance in the previous sentence applies 

in each State beginning 1 year after the affected 

source’s compliance date for that standard. 

Procedures governing the implementation of this 

provision are specified in Sec. 63.9(i). 

(6) If an owner or operator supervises one or more 

stationary sources affected by more than one standard 

established pursuant to section 112 of the Act, 

he/she may arrange by mutual agreement between the 

owner or operator and the Administrator (or the State

permitting authority) a common schedule on which 

periodic reports required for each source shall be 

submitted throughout the year. The allowance in the 

previous sentence applies in each State beginning 1 

year after the latest compliance date for any 

relevant standard established pursuant to section 112 

of the Act for any such affected source(s). 

Procedures governing the implementation of this 

provision are specified in Sec. 63.9(i). 

(7) If an owner or operator supervises one or more 

stationary sources affected by standards established 

pursuant to section 112 of the Act (as amended 

November 15, 1990) and standards set under part 60, 

part 61, or both such parts of this chapter, he/she 

may arrange by mutual agreement between the owner or 

operator and the Administrator (or the State 

permitting authority) a common schedule on which 

periodic reports required by each relevant (i.e., 

applicable) standard shall be submitted throughout 

the year. The allowance in the previous sentence 

applies in each State beginning 1 year after the 

stationary source is required to be in compliance 

with the relevant section 112 standard, or 1 year 

after the stationary source is required to be in 

compliance with the applicable part 60 or part 61 

standard, whichever is latest. Procedures governing 

the implementation of this provision are specified in 

Sec. 63.9(i). 

(b) General recordkeeping requirements. 

(1) The owner or operator of an affected source subject 

to the provisions of this part shall maintain files 

of all information (including all reports and 

notifications) required by this part recorded in a 

form suitable and readily available for expeditious 

inspection and review. The files shall be retained 

for at least 5 years following the date of each 

occurrence, measurement, maintenance, corrective 

action, report, or record. At a minimum, the most 

recent 2 years of data shall be retained on site. 

The remaining 3 years of data may be retained off 

site. Such files may be maintained on microfilm, on 

a computer, on computer floppy disks, on magnetic 

tape disks, or on microfiche. 

(2) The owner or operator of an affected source subject 

to the provisions of this part shall maintain 

relevant records for such source of-- 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-92 

(i) The occurrence and duration of each startup, 

shutdown, or malfunction of operation (i.e., 

process equipment); 

(ii) The occurrence and duration of each 

malfunction of the air pollution control 

equipment; 

(iii) All maintenance performed on the air pollution 

control equipment; 

(iv) Actions taken during periods of startup, 

shutdown, and malfunction (including 

corrective actions to restore malfunctioning 

process and air pollution control equipment to 

its normal or usual manner of operation) when 

such actions are different from the procedures 

specified in the affected source’s startup, 

shutdown, and malfunction plan (see Sec. 

63.6(e)(3)); 

(v) All information necessary to demonstrate 

conformance with the affected source’s 

startup, shutdown, and malfunction plan (see 

Sec. 63.6(e)(3)) when all actions taken during 

periods of startup, shutdown, and malfunction 

(including corrective actions to restore 

malfunctioning process and air pollution 

control equipment to its normal or usual 

manner of operation) are consistent with the 

procedures specified in such plan. (The 

information needed to demonstrate conformance 

with the startup, shutdown, and malfunction 

plan may be recorded using a “checklist,” or 

some other effective form of recordkeeping, in 

order to minimize the recordkeeping burden for 

conforming events); 

(vi) Each period during which a CMS is 

malfunctioning or inoperative (including outof-control periods); 

(vii) All required measurements needed to 

demonstrate compliance with a relevant 

standard (including, but not limited to, 15-

minute averages of CMS data, raw performance 

testing measurements, and raw performance 

evaluation measurements, that support data 

that the source is required to report); 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-93 

(A) This paragraph applies to owners or 

operators required to install a 

continuous emissions monitoring system 

(CEMS) where the CEMS installed is 

automated, and where the calculated data 

averages do not exclude periods of CEMS 

breakdown or malfunction. An automated 

CEMS records and reduces the measured 

data to the form of the pollutant 

emission standard through the use of a 

computerized data acquisition system. In 

lieu of maintaining a file of all CEMS 

sub hourly measurements as required under 

paragraph (b)(2)(vii) of this section, 

the owner or operator shall retain the 

most recent consecutive three averaging 

periods of sub hourly measurements and a 

file that contains a hard copy of the 

data acquisition system algorithm used to 

reduce the measured data into the 

reportable form of the standard. 

(B) This paragraph applies to owners or 

operators required to install a CEMS 

where the measured data is manually 

reduced to obtain the reportable form of 

the standard, and where the calculated 

data averages do not exclude periods of 

CEMS breakdown or malfunction. In lieu 

of maintaining a file of all CEMS sub 

hourly measurements as required under 

paragraph (b)(2)(vii) of this section, 

the owner or operator shall retain all 

sub hourly measurements for the most 

recent reporting period. The sub hourly 

measurements shall be retained for 120 

days from the date of the most recent 

summary or excess emission report 

submitted to the Administrator. 

(C) The Administrator or delegated authority, 

upon notification to the source, may 

require the owner or operator to maintain 

all measurements as required by paragraph 

(b)(2)(vii), if the administrator or the 

delegated authority determines these 

records are required to more accurately 

assess the compliance status of the 

affected source. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-94 

(viii) All results of performance tests, CMS 

performance evaluations, and opacity and 

visible emission observations; 

(ix) All measurements as may be necessary to 

determine the conditions of performance tests 

and performance evaluations; 

(x) All CMS calibration checks; 

(xi) All adjustments and maintenance performed on 

CMS; 

(xii) Any information demonstrating whether a source 

is meeting the requirements for a waiver of 

recordkeeping or reporting requirements under 

this part, if the source has been granted a 

waiver under paragraph (f) of this section; 

(xiii) All emission levels relative to the criterion 

for obtaining permission to use an alternative 

to the relative accuracy test, if the source 

has been granted such permission under Sec. 

63.8(f)(6); and 

(xiv) All documentation supporting initial 

notifications and notifications of compliance 

status under Sec. 63.9. 

(3) Recordkeeping requirement for applicability 

determinations. If an owner or operator determines 

that his or her stationary source that emits (or has 

the potential to emit, without considering controls) 

one or more hazardous air pollutants is not subject 

to a relevant standard or other requirement 

established under this part, the owner or operator 

shall keep a record of the applicability 

determination on site at the source for a period of 5 

years after the determination, or until the source 

changes its operations to become an affected source, 

whichever comes first. The record of the 

applicability determination shall include an analysis 

(or other information) that demonstrates why the 

owner or operator believes the source is unaffected 

(e.g., because the source is an area source). The 

analysis (or other information) shall be sufficiently 

detailed to allow the Administrator to make a finding 

about the source’s applicability status with regard 

to the relevant standard or other requirement. If 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-95 

relevant, the analysis shall be performed in 

accordance with requirements established in subparts 

of this part for this purpose for particular 

categories of stationary sources. If relevant, the 

analysis should be performed in accordance with EPA 

guidance materials published to assist sources in 

making applicability determinations under section 

112, if any. 

(c) Additional recordkeeping requirements for sources with 

continuous monitoring systems. In addition to complying 

with the requirements specified in paragraphs (b)(1) and 

(b)(2) of this section, the owner or operator of an 

affected source required to install a CMS by a relevant 

standard shall maintain records for such source of-- 

(1) All required CMS measurements (including monitoring 

data recorded during unavoidable CMS breakdowns and 

out-of-control periods); 

(2)-(4) [Reserved] 

(5) The date and time identifying each period during 

which the CMS was inoperative except for zero (lowlevel) and high-level checks; 

(6) The date and time identifying each period during 

which the CMS was out of control, as defined in Sec. 

63.8(c)(7); 

(7) The specific identification (i.e., the date and time 

of commencement and completion) of each period of 

excess emissions and parameter monitoring 

exceedances, as defined in the relevant standard(s), 

that occurs during startups, shutdowns, and 

malfunctions of the affected source; 

(8) The specific identification (i.e., the date and time 

of commencement and completion) of each time period 

of excess emissions and parameter monitoring 

exceedances, as defined in the relevant standard(s), 

that occurs during periods other than startups, 

shutdowns, and malfunctions of the affected source; 

(9) [Reserved] 

(10) The nature and cause of any malfunction (if known); 

(11) The corrective action taken or preventive measures 

adopted;

(12) The nature of the repairs or adjustments to the CMS 

that was inoperative or out of control; 

(13) The total process operating time during the reporting 

period; and 

(14) All procedures that are part of a quality control 

program developed and implemented for CMS under Sec. 

63.8(d). 

(15) In order to satisfy the requirements of paragraphs 

(c)(10) through (c)(12) of this section and to avoid 

duplicative recordkeeping efforts, the owner or 

operator may use the affected source’s startup, 

shutdown, and malfunction plan or records kept to 

satisfy the recordkeeping requirements of the 

startup, shutdown, and malfunction plan specified in 

Sec. 63.6(e), provided that such plan and records 

adequately address the requirements of paragraphs 

(c)(10) through (c)(12). 

(d) General reporting requirements. 

(1) Notwithstanding the requirements in this paragraph or 

paragraph (e) of this section, the owner or operator 

of an affected source subject to reporting 

requirements under this part shall submit reports to 

the Administrator in accordance with the reporting 

requirements in the relevant standard(s). 

(2) Reporting results of performance tests. Before a 

title V permit has been issued to the owner or 

operator of an affected source, the owner or operator 

shall report the results of any performance test 

under Sec. 63.7 to the Administrator. After a title 

V permit has been issued to the owner or operator of 

an affected source, the owner or operator shall 

report the results of a required performance test to 

the appropriate permitting authority. The owner or 

operator of an affected source shall report the 

results of the performance test to the Administrator 

(or the State with an approved permit program) before 

the close of business on the 60th day following the 

completion of the performance test, unless specified 

otherwise in a relevant standard or as approved 

otherwise in writing by the Administrator. The 

results of the performance test shall be submitted as 

part of the notification of compliance status 

required under Sec. 63.9(h).

I.D. Number: 115015AAE 

Application No.: 96030038 

9-97 

(3) Reporting results of opacity or visible emission 

observations. The owner or operator of an affected 

source required to conduct opacity or visible 

emission observations by a relevant standard shall 

report the opacity or visible emission results 

(produced using Test Method 9 or Test Method 22, or 

an alternative to these test methods) along with the 

results of the performance test required under Sec. 

63.7. If no performance test is required, or if 

visibility or other conditions prevent the opacity or 

visible emission observations from being conducted 

concurrently with the performance test required under 

Sec. 63.7, the owner or operator shall report the 

opacity or visible emission results before the close 

of business on the 30th day following the completion 

of the opacity or visible emission observations. 

(4) Progress reports. The owner or operator of an 

affected source who is required to submit progress 

reports as a condition of receiving an extension of 

compliance under Sec. 63.6(i) shall submit such 

reports to the Administrator (or the State with an 

approved permit program) by the dates specified in 

the written extension of compliance. 

(5) (i) Periodic startup, shutdown, and malfunction 

reports. If actions taken by an owner or 

operator during a startup, shutdown, or 

malfunction of an affected source (including 

actions taken to correct a malfunction) are 

consistent with the procedures specified in 

the source’s startup, shutdown, and 

malfunction plan [see Sec. 63.6(e)(3)], the 

owner or operator shall state such information 

in a startup, shutdown, and malfunction 

report. Reports shall only be required if a 

startup, shutdown, or malfunction occurred 

during the reporting period. The startup, 

shutdown, and malfunction report shall consist 

of a letter, containing the name, title, and 

signature of the owner or operator or other 

responsible official who is certifying its 

accuracy, that shall be submitted to the 

Administrator semiannually (or on a more 

frequent basis if specified otherwise in a 

relevant standard or as established otherwise 

by the permitting authority in the source’s 

title V permit). The startup, shutdown, and 

malfunction report shall be delivered or 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-98 

postmarked by the 30th day following the end 

of each calendar half (or other calendar 

reporting period, as appropriate). If the 

owner or operator is required to submit excess 

emissions and continuous monitoring system 

performance (or other periodic) reports under 

this part, the startup, shutdown, and 

malfunction reports required under this 

paragraph may be submitted simultaneously with 

the excess emissions and continuous monitoring 

system performance (or other) reports. If 

startup, shutdown, and malfunction reports are 

submitted with excess emissions and continuous 

monitoring system performance (or other 

periodic) reports, and the owner or operator 

receives approval to reduce the frequency of 

reporting for the latter under paragraph (e) 

of this section, the frequency of reporting 

for the startup, shutdown, and malfunction 

reports also may be reduced if the 

Administrator does not object to the intended 

change. The procedures to implement the 

allowance in the preceding sentence shall be 

the same as the procedures specified in 

paragraph (e)(3) of this section. 

(ii) Immediate startup, shutdown, and malfunction 

reports. Notwithstanding the allowance to 

reduce the frequency of reporting for periodic 

startup, shutdown, and malfunction reports 

under paragraph (d)(5)(i) of this section, any 

time an action taken by an owner or operator 

during a startup, shutdown, or malfunction 

(including actions taken to correct a 

malfunction) is not consistent with the 

procedures specified in the affected source’s 

startup, shutdown, and malfunction plan, the 

owner or operator shall report the actions 

taken for that event within 2 working days 

after commencing actions inconsistent with the 

plan followed by a letter within 7 working 

days after the end of the event. The 

immediate report required under this paragraph 

shall consist of a telephone call (or 

facsimile (FAX) transmission) to the 

Administrator within 2 working days after 

commencing actions inconsistent with the plan, 

and it shall be followed by a letter, 

delivered or postmarked within 7 working days 

after the end of the event, that contains the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-99 

name, title, and signature of the owner or 

operator or other responsible official who is 

certifying its accuracy, explaining the 

circumstances of the event, the reasons for 

not following the startup, shutdown, and 

malfunction plan, and whether any excess 

emissions and/or parameter monitoring 

exceedances are believed to have occurred. 

Notwithstanding the requirements of the 

previous sentence, after the effective date of 

an approved permit program in the State in 

which an affected source is located, the owner 

or operator may make alternative reporting 

arrangements, in advance, with the permitting 

authority in that State. Procedures governing 

the arrangement of alternative reporting 

requirements under this paragraph are 

specified in Sec. 63.9(i). 

(e) Additional reporting requirements for sources with 

continuous monitoring systems— 

(1) General. When more than one CEMS is used to measure 

the emissions from one affected source (e.g., 

multiple breechings, multiple outlets), the owner or 

operator shall report the results as required for 

each CEMS. 

(2) Reporting results of continuous monitoring system 

performance evaluations. 

(i) The owner or operator of an affected source 

required to install a CMS by a relevant 

standard shall furnish the Administrator a 

copy of a written report of the results of the 

CMS performance evaluation, as required under 

Sec. 63.8(e), simultaneously with the results 

of the performance test required under Sec. 

63.7, unless otherwise specified in the 

relevant standard. 

(ii) The owner or operator of an affected source 

using a COMS to determine opacity compliance 

during any performance test required under 

Sec. 63.7 and described in Sec. 63.6(d)(6) 

shall furnish the Administrator two or, upon 

request, three copies of a written report of 

the results of the COMS performance evaluation 

conducted under Sec. 63.8(e). The copies 

shall be furnished at least 15 calendar days 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex

before the performance test required under 

Sec. 63.7 is conducted. 

(3) Excess emissions and continuous monitoring system 

performance report and summary report. 

(i) Excess emissions and parameter monitoring 

exceedances are defined in relevant standards. 

The owner or operator of an affected source 

required to install a CMS by a relevant 

standard shall submit an excess emissions and 

continuous monitoring system performance 

report and/or a summary report to the 

Administrator semiannually, except when-- 

(A) More frequent reporting is specifically 

required by a relevant standard; 

(B) The Administrator determines on a caseby-case basis that more frequent 

reporting is necessary to accurately 

assess the compliance status of the 

source; or 

(C) [Reserved] 

(ii) Request to reduce frequency of excess 

emissions and continuous monitoring system 

performance reports. Notwithstanding the 

frequency of reporting requirements specified 

in paragraph (e)(3)(i) of this section, an 

owner or operator who is required by a 

relevant standard to submit excess emissions 

and continuous monitoring system performance 

(and summary) reports on a quarterly (or more 

frequent) basis may reduce the frequency of 

reporting for that standard to semiannual if 

the following conditions are met: 

(A) For 1 full year (e.g., 4 quarterly or 12 

monthly reporting periods) the affected 

source’s excess emissions and continuous 

monitoring system performance reports 

continually demonstrate that the source 

is in compliance with the relevant 

standard; 

(B) The owner or operator continues to comply 

with all recordkeeping and monitoring 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-101 

requirements specified in this subpart

and the relevant standard; and 

(C) The Administrator does not object to a 

reduced frequency of reporting for the 

affected source, as provided in paragraph 

(e)(3)(iii) of this section. 

(iii) The frequency of reporting of excess emissions 

and continuous monitoring system performance 

(and summary) reports required to comply with 

a relevant standard may be reduced only after 

the owner or operator notifies the 

Administrator in writing of his or her 

intention to make such a change and the 

Administrator does not object to the intended 

change. In deciding whether to approve a 

reduced frequency of reporting, the 

Administrator may review information 

concerning the source’s entire previous 

performance history during the 5-year 

recordkeeping period prior to the intended 

change, including performance test results, 

monitoring data, and evaluations of an owner 

or operator’s conformance with operation and 

maintenance requirements. Such information 

may be used by the Administrator to make a 

judgment about the source’s potential for 

noncompliance in the future. If the 

Administrator disapproves the owner or 

operator’s request to reduce the frequency of 

reporting, the Administrator will notify the 

owner or operator in writing within 45 days 

after receiving notice of the owner or 

operator’s intention. The notification from 

the Administrator to the owner or operator 

will specify the grounds on which the 

disapproval is based. In the absence of a 

notice of disapproval within 45 days, approval 

is automatically granted. 

(iv) As soon as CMS data indicate that the source 

is not in compliance with any emission 

limitation or operating parameter specified in 

the relevant standard, the frequency of 

reporting shall revert to the frequency 

specified in the relevant standard, and the 

owner or operator shall submit an excess 

emissions and continuous monitoring system 

performance (and summary) report for the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-102 

noncomplying emission points at the next 

appropriate reporting period following the 

noncomplying event. After demonstrating 

ongoing compliance with the relevant standard 

for another full year, the owner or operator 

may again request approval from the 

Administrator to reduce the frequency of 

reporting for that standard, as provided for 

in paragraphs (e)(3)(ii) and (e)(3)(iii) of 

this section. 

(v) Content and submittal dates for excess 

emissions and monitoring system performance 

reports. All excess emissions and monitoring 

system performance reports and all summary 

reports, if required, shall be delivered or 

postmarked by the 30th day following the end 

of each calendar half or quarter, as 

appropriate. Written reports of excess 

emissions or exceedances of process or control 

system parameters shall include all the 

information required in paragraphs (c)(5) 

through (c)(13) of this section, in Sec. 

63.8(c)(7) and Sec. 63.8(c)(8), and in the 

relevant standard, and they shall contain the 

name, title, and signature of the responsible 

official who is certifying the accuracy of the 

report. When no excess emissions or 

exceedances of a parameter have occurred, or a 

CMS has not been inoperative, out of control, 

repaired, or adjusted, such information shall 

be stated in the report. 

(vi) Summary report. As required under paragraphs 

(e)(3)(vii) and (e)(3)(viii) of this section, 

one summary report shall be submitted for the 

hazardous air pollutants monitored at each 

affected source (unless the relevant standard 

specifies that more than one summary report is 

required, e.g., one summary report for each 

hazardous air pollutant monitored). The 

summary report shall be entitled “Summary 

Report--Gaseous and Opacity Excess Emission 

and Continuous Monitoring System Performance” 

and shall contain the following information: 

(A) The company name and address of the 

affected source;

(f) Waiver of recordkeeping or reporting requirements. 

(1) Until a waiver of a recordkeeping or reporting 

requirement has been granted by the Administrator 

under this paragraph, the owner or operator of an 

affected source remains subject to the requirements 

of this section. 

(2) Recordkeeping or reporting requirements may be waived 

upon written application to the Administrator if, in 

the Administrator’s judgment, the affected source is 

achieving the relevant standard(s), or the source is 

operating under an extension of compliance, or the 

owner or operator has requested an extension of 

compliance and the Administrator is still considering 

that request. 

(3) If an application for a waiver of recordkeeping or 

reporting is made, the application shall accompany 

the request for an extension of compliance under Sec. 

63.6(i), any required compliance progress report or 

compliance status report required under this part 

(such as under Sec. 63.6(i) and Sec. 63.9(h)) or in 

the source’s title V permit, or an excess emissions 

and continuous monitoring system performance report 

required under paragraph (e) of this section, 

whichever is applicable. The application shall 

include whatever information the owner or operator 

considers useful to convince the Administrator that a 

waiver of recordkeeping or reporting is warranted. 

(4) The Administrator will approve or deny a request for 

a waiver of recordkeeping or reporting requirements 

under this paragraph when he/she-- 

(i) Approves or denies an extension of compliance; 

or 

(ii) Makes a determination of compliance following 

the submission of a required compliance status 

report or excess emissions and continuous 

monitoring systems performance report; or

Sec. 63.12 State authority and delegations. 

(a) The provisions of this part shall not be construed in any 

manner to preclude any State or political subdivision 

thereof from-- 

(1) Adopting and enforcing any standard, limitation, 

prohibition, or other regulation applicable to an 

affected source subject to the requirements of this 

part, provided that such standard, limitation, 

prohibition, or regulation is not less stringent than 

any requirement applicable to such source established 

under this part; 

(2) Requiring the owner or operator of an affected source 

to obtain permits, licenses, or approvals prior to 

initiating construction, reconstruction, 

modification, or operation of such source; or 

(3) Requiring emission reductions in excess of those 

specified in subpart D of this part as a condition 

for granting the extension of compliance authorized 

by section 112(i)(5) of the Act. 

(b) (1) Section 112(l) of the Act directs the Administrator 

to delegate to each State, when appropriate, the 

authority to implement and enforce standards and 

other requirements pursuant to section 112 for 

stationary sources located in that State. Because of 

the unique nature of radioactive material, delegation 

of authority to implement and enforce standards that 

control radionuclides may require separate approval. 

(2) Subpart E of this part establishes procedures 

consistent with section 112(l) for the approval of

State rules or programs to implement and enforce 

applicable Federal rules promulgated under the 

authority of section 112. Subpart E also establishes 

procedures for the review and withdrawal of section 

112 implementation and enforcement authorities 

granted through a section 112(l) approval. 

(c) All information required to be submitted to the EPA under 

this part also shall be submitted to the appropriate State 

agency of any State to which authority has been delegated 

under section 112(l) of the Act, provided that each 

specific delegation may exempt sources from a certain 

Federal or State reporting requirement. The Administrator 

may permit all or some of the information to be submitted 

to the appropriate State agency only, instead of to the 

EPA and the State agency.

40 CFR 63 Subpart GGGG--National Emission Standards for Hazardous 

Air Pollutants: Solvent Extraction for Vegetable Oil 

Production 

Source: 66 FR 19011, Apr. 12, 2001, unless otherwise noted. 

What This Subpart Covers 

Sec. 63.2830 What is the purpose of this subpart? 

This subpart establishes national emission standards for 

hazardous air pollutants (NESHAP) for emissions during vegetable 

oil production. This subpart limits hazardous air pollutant 

(HAP) emissions from specified vegetable oil production 

processes. This subpart also establishes requirements to 

demonstrate initial and continuous compliance with the emission 

standards. 

Sec. 63.2831 Where can I find definitions of key words used in 

this subpart? 

You can find definitions of key words used in this subpart in 

Sec. 63.2872. 

Sec. 63.2832 Am I subject to this subpart? 

(a) You are an affected source subject to this subpart if you 

meet all of the criteria listed in paragraphs (a)(1) and 

(2) of this section: 

(1) You own or operate a vegetable oil production process 

that is a major source of HAP emissions or is 

collocated within a plant site with other sources 

that are individually or collectively a major source 

of HAP emissions. 

(i) A vegetable oil production process is defined 

in Sec. 63.2872. In general, it is the 

collection of continuous process equipment and 

activities that produce crude vegetable oil 

and meal products by removing oil from 

oilseeds listed in Table 1 to Sec. 63.2840 

through direct contact with an organic 

solvent, such as a hexane isomer blend. 

(ii) A major source of HAP emissions is a plant 

site that emits or has the potential to emit 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-120 

any single HAP at a rate of 10 tons (9.07 

megagrams) or more per year or any combination 

of HAP at a rate of 25 tons (22.68 megagrams) 

or more per year. 

(2) Your vegetable oil production process processes any 

combination of eight types of oilseeds listed in 

paragraphs (a)(2)(i) through (viii) of this section: 

(i) Corn germ; 

(ii) Cottonseed; 

(iii) Flax; 

(iv) Peanut; 

(v) Rapeseed (for example, canola); 

(vi) Safflower; 

(vii) Soybean; and 

(viii) Sunflower. 

(b) You are not subject to this subpart if your vegetable oil 

production process meets any of the criteria listed in 

paragraphs (b)(1) through (4) of this section: 

(1) It uses only mechanical extraction techniques that 

use no organic solvent to remove oil from a listed 

oilseed. 

(2) It uses only batch solvent extraction and batch 

desolventizing equipment. 

(3) It processes only agricultural products that are not 

listed oilseeds as defined in Sec. 63.2872. 

(4) It functions only as a research and development 

facility and is not a major source. 

(c) As listed in Sec. 63.1(c)(5) of the General Provisions, if 

your HAP emissions increase such that you become a major 

source, then you are subject to all of the requirements of 

this subpart.

Sec. 63.2833 Is my source categorized as existing or new? 

(a) This subpart applies to each existing and new affected 

source. You must categorize your vegetable oil production 

process as either an existing or a new source in 

accordance with the criteria in Table 1 of this section, 

as follows: 

TABLE 1 TO § 63.2833.—CATEGORIZING YOUR SOURCE AS EXISTING

(b) Reconstruction of a source. Any affected source is 

reconstructed if components are replaced so that the 

criteria in the definition of reconstruction in Sec. 63.2 

are satisfied. In general, a vegetable oil production 

process is reconstructed if the fixed capital cost of the 

new components exceeds 50 percent of the fixed capital 

cost for constructing a new vegetable oil production 

process, and it is technically and economically feasible 

for the reconstructed source to meet the relevant new 

source requirements of this subpart. The effect of 

reconstruction on the categorization of your existing and 

new affected source is described in paragraphs (b)(1) and 

(2) of this section: 

(1) After reconstruction of an existing source, the 

affected source is recategorized as a new source and 

becomes subject to the new source requirements of 

this subpart. 

(2) After reconstruction of a new source, the affected 

source remains categorized as a new source and 

remains subject to the new source requirements of 

this subpart. 

(c) Significant modification of a source. A significant 

modification to an affected source is a term specific to 

this subpart and is defined in Sec. 63.2872. 

(1) In general, a significant modification to your source 

consists of adding new equipment or the modification 

of existing equipment within the affected source that 

significantly affects solvent losses from the 

affected source. Examples include adding or 

replacing extractors, desolventizer-toasters 

(conventional and specialty), and meal dryer-coolers. 

All other significant modifications must meet the 

criteria listed in paragraphs (c)(1)(i) and (ii) of 

this section: 

(i) The fixed capital cost of the modification 

represents a significant percentage of the 

fixed capital cost of building a comparable 

new vegetable oil production process. 

(ii) It does not constitute reconstruction as 

defined in Sec. 63.2. 

(2) A significant modification has no effect on the 

categorization of your source as existing and new. 

An existing source remains categorized as an existing

source and subject to the existing source 

requirements of this subpart. A new source remains 

categorized as a new source and subject to the new 

source requirements of this subpart. 

(d) Changes in the type of oilseed processed by your affected 

source does not affect the categorization of your source 

as new or existing. Recategorizing an affected source 

from existing to new occurs only when you add or modify 

process equipment within the source which meets the 

definition of reconstruction. 

Sec. 63.2834 When do I have to comply with the standards in this 

subpart? 

You must comply with this subpart in accordance with one of the 

schedules in Table 1 of this section, as follows:

Standards 

Sec. 63.2840 What emission requirements must I meet?

(a) (1) The emission requirements limit the number of gallons 

of HAP lost per ton of listed oilseeds processed. 

For each operating month, you must calculate a 

compliance ratio which compares your actual HAP loss 

to your allowable HAP loss for the previous 12 

operating months as shown in Equation 1 of this 

section. An operating month, as defined in Sec. 

63.2872, is any calendar month in which a source 

processes a listed oilseed, excluding any entire

(b) When your source has processed listed oilseed for 12 

operating months, calculate the compliance ratio by the 

end of each calendar month following an operating month 

using Equation 2 of this section. When calculating your 

compliance ratio, consider the conditions and exclusions 

in paragraphs (b)(1) through (6) of this section: 

(1) If your source processes any quantity of listed 

oilseeds in a calendar month and the source is not 

operating under an initial startup period or 

malfunction period subject to Sec. 63.2850, then you 

must categorize the month as an operating month, as 

defined in Sec. 63.2872. 

(2) The 12-month compliance ratio may include operating 

months occurring prior to a source shutdown and 

operating months that follow after the source resumes 

operation. 

(3) If your source shuts down and processes no listed 

oilseed for an entire calendar month, then you must 

categorize the month as a nonoperating month, as 

defined in Sec. 63.2872. Exclude any nonoperating 

months from the compliance ratio determination. 

(4) If your source is subject to an initial startup 

period as defined in Sec. 63.2872, exclude from the 
CAAPP PERMIT

compliance ratio determination any solvent and 

oilseed information recorded for the initial startup 

period. 

(5) If your source is subject to a malfunction period as 

defined in Sec. 63.2872, exclude from the compliance 

ratio determination any solvent and oilseed 

information recorded for the malfunction period. 

(6) For sources processing cottonseed or specialty 

soybean, the solvent loss factor you use to determine 

the compliance ratio may change each operating month 

depending on the tons of oilseed processed during all 

normal operating periods in a 12 operating month 

period. 

(c) If the compliance ratio is less than or equal to 1.00, 

your source was in compliance with the HAP emission 

requirements for the previous operating month. 

(d) To determine the compliance ratio in Equation 2 of this 

section, you must select the appropriate oilseed solvent 

loss factor from Table 1 of this section. First, 

determine whether your source is new or existing using 

Table 1 of Sec. 63.2833. Then, under the appropriate 

existing or new source column, select the oilseed solvent 

loss factor that corresponds to each type oilseed or 

process operation for each operating month.

malfunction (including the period reasonably necessary to 

correct the malfunction), or starts up after a shutdown 

resulting from a malfunction, then you must meet the 

requirements associated with one of two compliance 

options. Routine or scheduled process startups and 

shutdowns resulting from, but not limited to, market 

demands, maintenance activities, and switching types of 

oilseed processed, are not startups or shutdowns resulting 

from a malfunction and, therefore, do not qualify for this 

provision. Within 15 days of the beginning date of the 

malfunction, you must choose to comply with one of the 

options listed in paragraphs (e)(1) through (2) of this 

section: 

(1) Normal operation. Your source must meet all of the

Sec. 63.2851 What is a plan for demonstrating compliance?

(a) You must develop and implement a written plan for 

demonstrating compliance that provides the detailed 

procedures you will follow to monitor and record data 

necessary for demonstrating compliance with this subpart. 

Procedures followed for quantifying solvent loss from the 

source and amount of oilseed processed vary from source to 

source because of site-specific factors such as equipment 

design characteristics and operating conditions. Typical 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-127 

procedures include one or more accurate measurement 

methods such as weigh scales, volumetric displacement, and 

material mass balances. Because the industry does not 

have a uniform set of procedures, you must develop and 

implement your own site-specific plan for demonstrating 

compliance before the compliance date for your source. 

You must also incorporate the plan for demonstrating 

compliance by reference in the source’s title V permit and 

keep the plan on-site and readily available as long as the 

source is operational. If you make any changes to the 

plan for demonstrating compliance, then you must keep all 

previous versions of the plan and make them readily 

available for inspection for at least 5 years after each 

revision. The plan for demonstrating compliance must 

include the items in paragraphs (a)(1) through (7) of this 

section: 

(1) The name and address of the owner or operator. 

(2) The physical address of the vegetable oil production 

process. 

(3) A detailed description of all methods of measurement 

your source will use to determine your solvent 

losses, HAP content of solvent, and the tons of each 

type of oilseed processed. 

(4) When each measurement will be made. 

(5) Examples of each calculation you will use to 

determine your compliance status. Include examples 

of how you will convert data measured with one 

parameter to other terms for use in compliance 

determination. 

(6) Example logs of how data will be recorded. 

(7) A plan to ensure that the data continue to meet 

compliance demonstration needs. 

(b) The responsible agency of these NESHAP may require you to 

revise your plan for demonstrating compliance. The 

responsible agency may require reasonable revisions if the 

procedures lack detail, are inconsistent or do not 

accurately determine solvent loss, HAP content of the 

solvent, or the tons of oilseed processed.

Sec. 63.2852 What is a startup, shutdown, and malfunction plan? 

You must develop a written SSM plan in accordance with Sec. 

63.6(e)(3) and implement the plan, when applicable. You must 

complete the SSM plan before the compliance date for your source. 

You must also incorporate the SSM plan by reference in your 

source’s title V permit and keep the SSM plan on-site and readily 

available as long as the source is operational. The SSM plan 

provides detailed procedures for operating and maintaining your 

source to minimize emissions during a qualifying SSM event for 

which the source chooses the Sec. 63.2850(e)(2) malfunction 

period, or the Sec. 63.2850(c)(2) or (d)(2) initial startup 

period. The SSM plan must specify a program of corrective action 

for malfunctioning process and air pollution control equipment 

and reflect the best practices now in use by the industry to 

minimize emissions. Some or all of the procedures may come from 

plans you developed for other purposes such as a Standard 

Operating Procedure manual or an Occupational Safety and Health 

Administration Process Safety Management plan. To qualify as a 

SSM plan, other such plans must meet all the applicable 

requirements of these NESHAP. 

Sec. 63.2853 How do I determine the actual solvent loss? 

By the end of each calendar month following an operating month, 

you must determine the total solvent loss in gallons for the 

previous operating month. The total solvent loss for an 

operating month includes all solvent losses that occur during 

normal operating periods within the operating month. If you have 

determined solvent losses for 12 or more operating months, then 

you must also determine the 12 operating months rolling sum of 

actual solvent loss in gallons by summing the monthly actual 

solvent loss for the previous 12 operating months. The 12 

operating months rolling sum of solvent loss is the “actual 

solvent loss,” which is used to calculate your compliance ratio 

as described in Sec. 63.2840. 

(a) To determine the actual solvent loss from your source, 

follow the procedures in your plan for demonstrating 

compliance to determine the items in paragraphs (a)(1) 

through (7) of this section: 

(1) The dates that define each operating status period 

during a calendar month. The dates that define each 

operating status period include the beginning date of 

each calendar month and the date of any change in the 

source operating status. If the source maintains the 

same operating status during an entire calendar 

month, these dates are the beginning and ending dates 

of the calendar month. If, prior to the effective 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-129 

date of this rule, your source determines the solvent 

loss on an accounting month, as defined in Sec. 

63.2872, rather than a calendar month basis, and you 

have 12 complete accounting months of approximately 

equal duration in a calendar year, you may substitute 

the accounting month time interval for the calendar 

month time interval. If you choose to use an 

accounting month rather than a calendar month, you 

must document this measurement frequency selection in 

your plan for demonstrating compliance, and you must 

remain on this schedule unless you request and 

receive written approval from the agency responsible 

for these NESHAP. 

(2) Source operating status. You must categorize the 

operating status of your source for each recorded 

time interval in accordance with criteria in Table 1 

of this section, as follows: 

TABLE 1 OF § 63.2853.—CATEGORIZING YOUR SOURCE 

OPERATING STATUS 

If during a recorded time 

interval 

then your source 

operating status is 

(i) Your source processes any 

amount of listed oilseed and 

source is not operating under an 

initial startup operating period 

or a malfunction period subject 

to § 63.2850(c)(2), (d)(2), or 

(e)(2). 

A normal operating 

period. 

(ii) Your source processes no 

agricultural product and your 

source is not operating under an 

initial startup period or malfunction period subject to § 

63.2850(c)(2), (d)(2), or (e)(2). 

A non-operating 

period. 

(iii) You choose to operate your 

source under an initial startup 

period subject to § 63.2850(c)(2) 

or (d)(2). 

An initial startup 

period. 

(iv) You choose to operate your 

source under a malfunction period 

subject to § 63.2850(e)(2). 

A malfunction period. 

(v) Your source processes 

agricultural products not defined 

as listed oilseed. 

An exempt period. 

(3) Measuring the beginning and ending solvent inventory. 

You are required to measure and record the solvent 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-130 

inventory on the beginning and ending dates of each 

normal operating period that occurs during an 

operating month. An operating month is any calendar 

month with at least one normal operating period. You 

must consistently follow the procedures described in 

your plan for demonstrating compliance, as specified 

in Sec. 63.2851, to determine the extraction solvent 

inventory, and maintain readily available records of 

the actual solvent loss inventory, as described in 

Sec. 63.2862(c)(1). In general, you must measure and 

record the solvent inventory only when the source is 

actively processing any type of agricultural product. 

When the source is not active, some or all of the 

solvent working capacity is transferred to solvent 

storage tanks which can artificially inflate the 

solvent inventory. 

(4) Gallons of extraction solvent received. Record the 

total gallons of extraction solvent received in each 

shipment. For most processes, the gallons of solvent 

received represents purchases of delivered solvent 

added to the solvent storage inventory. However, if 

your process refines additional vegetable oil from 

off-site sources, recovers solvent from the off-site 

oil, and adds it to the on-site solvent inventory, 

then you must determine the quantity of recovered 

solvent and include it in the gallons of extraction 

solvent received. 

(5) Solvent inventory adjustments. In some situations, 

solvent losses determined directly from the measured 

solvent inventory and quantity of solvent received is 

not an accurate estimate of the “actual solvent loss” 

for use in determining compliance ratios. In such 

cases, you may adjust the total solvent loss for each 

normal operating period as long as you provide a 

reasonable justification for the adjustment. 

Situations that may require adjustments of the total 

solvent loss include, but are not limited to, 

situations in paragraphs (a)(5)(i) and (ii) of this 

section: 

(i) Solvent destroyed in a control device. You 

may use a control device to reduce solvent 

emissions to meet the emission standard. The 

use of a control device does not alter the 

emission limit for the source. If you use a 

control device that reduces solvent emissions 

through destruction of the solvent instead of 

recovery, then determine the gallons of 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-131 

solvent that enter the control device and are 

destroyed there during each normal operating 

period. All solvent destroyed in a control 

device during a normal operating period can be 

subtracted from the total solvent loss. 

Examples of destructive emission control 

devices include catalytic incinerators, 

boilers, or flares. Identify and describe, in 

your plan for demonstrating compliance, each 

type of reasonable and sound measurement 

method that you use to quantify the gallons of 

solvent entering and exiting the control 

device and to determine the destruction 

efficiency of the control device. You may use 

design evaluations to document the gallons of 

solvent destroyed or removed by the control 

device instead of performance testing under 

Sec. 63.7. The design evaluations must be 

based on the procedures and options described 

in Sec. 63.985(b)(1)(i)(A) through (C) or Sec. 

63.11, as appropriate. All data, assumptions, 

and procedures used in such evaluations must 

be documented and available for inspection. 

If you use performance testing to determine 

solvent flow rate to the control device or 

destruction efficiency of the device, follow 

the procedures as outlined in Sec. 

63.997(e)(1) and (2). Instead of periodic 

performance testing to demonstrate continued 

good operation of the control device, you may 

develop a monitoring plan, following the 

procedures outlined in Sec. 63.988(c) and 

using operational parametric measurement 

devices such as fan parameters, percent 

measurements of lower explosive limits, and 

combustion temperature. 

(ii) Changes in solvent working capacity. In 

records you keep on-site, document any process 

modifications resulting in changes to the 

solvent working capacity in your vegetable oil 

production process. Solvent working capacity 

is defined in Sec. 63.2872. In general, 

solvent working capacity is the volume of 

solvent normally retained in solvent recovery 

equipment such as the extractor, 

desolventizer-toaster, solvent storage, 

working tanks, mineral oil absorber, 

condensers, and oil/solvent distillation 

system. If the change occurs during a normal 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-132 

operating period, you must determine the 

difference in working solvent volume and make 

a one-time documented adjustment to the 

solvent inventory. 

(b) Use Equation 1 of this section to determine the actual 

solvent loss occurring from your affected source for all 

normal operating periods recorded within a calendar month. 

Equation 1 of this section follows:

determined in paragraph (a)(3) of this 

section. 

SOLVE = Gallons of solvent in the inventory at the end 

of normal operating period “i” as determined 

in paragraph (a)(3) of this section. 

SOLVR = Gallons of solvent received between the 

beginning and ending inventory dates of normal 

operating period “i” as determined in 

paragraph (a)(4) of this section. 

SOLVA = Gallons of solvent added or removed from the 

extraction solvent inventory during normal 

operating period “i” as determined in 

paragraph (a)(5) of this section. 

n = Number of normal operating periods in a 

calendar month. 

(c) The actual solvent loss is the total solvent losses during 

normal operating periods for the previous 12 operating 

months. You determine your actual solvent loss by summing 

the monthly actual solvent losses for the previous 12 

operating months. You must record the actual solvent loss 

by the end of each calendar month following an operating 

month. Use the actual solvent loss in Equation 2 of Sec. 

63.2840 to determine the compliance ratio. Actual solvent 

loss does not include losses that occur during operating 

status periods listed in paragraphs (c)(1) through (4) of 
CAAPP PERMIT

this section. If any one of these four operating status 

periods span an entire month, then the month is treated as 

nonoperating and there is no compliance ratio 

determination. 

(1) Nonoperating periods as described in paragraph 

(a)(2)(ii) of this section. 

(2) Initial startup periods as described in Sec. 

63.2850(c)(2) or (d)(2). 

(3) Malfunction periods as described in Sec. 

63.2850(e)(2). 

(4) Exempt operation periods as described in paragraph 

(a)(2)(v) of this section. 

Sec. 63.2854 How do I determine the weighted average volume 

fraction of HAP in the actual solvent loss? 

(a) This section describes the information and procedures you 

must use to determine the weighted average volume fraction 

of HAP in extraction solvent received for use in your 

vegetable oil production process. By the end of each 

calendar month following an operating month, determine the 

weighted average volume fraction of HAP in extraction 

solvent received since the end of the previous operating 

month. If you have determined the monthly weighted 

average volume fraction of HAP in solvent received for 12 

or more operating months, then also determine an overall 

weighted average volume fraction of HAP in solvent 

received for the previous 12 operating months. Use the 

volume fraction of HAP determined as a 12 operating months 

weighted average in Equation 2 of Sec. 63.2840 to 

determine the compliance ratio. 

(b) To determine the volume fraction of HAP in the extraction 

solvent determined as a 12 operating months weighted 

average, you must comply with paragraphs (b)(1) through 

(3) of this section: 

(1) Record the volume fraction of each HAP comprising 

more than 1 percent by volume of the solvent in each 

delivery of solvent, including solvent recovered from 

off-site oil. To determine the HAP content of the 

material in each delivery of solvent, the reference 

method is EPA Method 311 of appendix A of this part. 

You may use EPA Method 311, an approved alternative 

method, or any other reasonable means for determining 

the HAP content. Other reasonable means of 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-134 

determining HAP content include, but are not limited 

to, a material safety data sheet or a manufacturer’s 

certificate of analysis. A certificate of analysis 

is a legal and binding document provided by a solvent 

manufacturer. The purpose of a certificate of 

analysis is to list the test methods and analytical 

results that determine chemical properties of the 

solvent and the volume percentage of all HAP 

components present in the solvent at quantities 

greater than 1 percent by volume. You are not 

required to test the materials that you use, but the 

Administrator may require a test using EPA Method 311 

(or an approved alternative method) to confirm the 

reported HAP content. However, if the results of an 

analysis by EPA Method 311 are different from the HAP 

content determined by another means, the EPA Method 

311 results will govern compliance determinations. 

(2) Determine the weighted average volume fraction of HAP 

in the extraction solvent each operating month. The 

weighted average volume fraction of HAP for an 

operating month includes all solvent received since 

the end of the last operating month, regardless of 

the operating status at the time of the delivery. 

Determine the monthly weighted average volume 

fraction of HAP by summing the products of the HAP 

volume fraction of each delivery and the volume of 

each delivery and dividing the sum by the total 

volume of all deliveries as expressed in Equation 1 

of this section. Record the result by the end of 

each calendar month following an operating month.

Total Received = Total gallons of extraction solvent

previous operating month. 

n = Number of extraction solvent deliveries since 

the end of the previous operating month. 

(3) Determine the volume fraction of HAP in your 

extraction solvent as a 12 operating months weighted 

average. When your source has processed oilseed for 

12 operating months, sum the products of the monthly 

weighted average HAP volume fraction and 

corresponding volume of solvent received, and divide 

the sum by the total volume of solvent received for 

the 12 operating months, as expressed by Equation 2 

of this section. Record the result by the end of 

each calendar month following an operating month and 

use it in Equation 2 of Sec. 63.2840 to determine the 

compliance ratio. Equation 2 of this section

month “i” as determined in accordance 

with paragraph (b)(1) of this section. 

Total Received = Total gallons of extraction solvent 

received during the previous 12 

operating months. 

Sec. 63.2855 How do I determine the quantity of oilseed 

processed? 

All oilseed measurements must be determined on an as received 

basis, as defined in Sec. 63.2872. The as received basis refers 

to the oilseed chemical and physical characteristics as initially 

received by the source and prior to any oilseed handling and 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-136 

processing. By the end of each calendar month following an 

operating month, you must determine the tons as received of each 

listed oilseed processed for the operating month. The total 

oilseed processed for an operating month includes the total of 

each oilseed processed during all normal operating periods that 

occur within the operating month. If you have determined the 

tons of oilseed processed for 12 or more operating months, then 

you must also determine the 12 operating months rolling sum of 

each type oilseed processed by summing the tons of each type of 

oilseed processed for the previous 12 operating months. The 12 

operating months rolling sum of each type of oilseed processed is 

used to calculate the compliance ratio as described in Sec. 

63.2840. 

(a) To determine the tons as received of each type of oilseed 

processed at your source, follow the procedures in your 

plan for demonstrating compliance to determine the items 

in paragraphs (a)(1) through (5) of this section: 

(1) The dates that define each operating status period. 

The dates that define each operating status period 

include the beginning date of each calendar month and 

the date of any change in the source operating 

status. If, prior to the effective date of this 

rule, your source determines the oilseed inventory on 

an accounting month rather than a calendar month 

basis, and you have 12 complete accounting months of 

approximately equal duration in a calendar year, you 

may substitute the accounting month time interval for 

the calendar month time interval. If you choose to 

use an accounting month rather than a calendar month, 

you must document this measurement frequency 

selection in your plan for demonstrating compliance, 

and you must remain on this schedule unless you 

request and receive written approval from the agency 

responsible for these NESHAP. The dates on each 

oilseed inventory log must be consistent with the 

dates recorded for the solvent inventory. 

(2) Source operating status. You must categorize the 

source operation for each recorded time interval. 

The source operating status for each time interval 

recorded on the oilseed inventory for each type of 

oilseed must be consistent with the operating status 

recorded on the solvent inventory logs as described 

in Sec. 63.2853(a)(2). 

(3) Measuring the beginning and ending inventory for each 

oilseed. You are required to measure and record the 

oilseed inventory on the beginning and ending dates 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-137 

of each normal operating period that occurs during an 

operating month. An operating month is any calendar 

month with at least one normal operating period. You 

must consistently follow the procedures described in 

your plan for demonstrating compliance, as specified 

in Sec. 63.2851, to determine the oilseed inventory 

on an as received basis and maintain readily 

available records of the oilseed inventory as 

described by Sec. 63.2862(c)(3). 

(4) Tons of each oilseed received. Record the type of 

oilseed and tons of each shipment of oilseed received 

and added to your on-site storage. 

(5) Oilseed inventory adjustments. In some situations, 

determining the quantity of oilseed processed 

directly from the measured oilseed inventory and 

quantity of oilseed received is not an accurate 

estimate of the tons of oilseed processed for use in 

determining compliance ratios. For example, spoiled 

and molded oilseed removed from storage but not 

processed by your source will result in an 

overestimate of the quantity of oilseed processed. 

In such cases, you must adjust the oilseed inventory 

and provide a justification for the adjustment. 

Situations that may require oilseed inventory 

adjustments include, but are not limited to, the 

situations listed in paragraphs (a)(5)(i) through (v) 

of this section: 

(i) Oilseed that mold or otherwise become 

unsuitable for processing. 

(ii) Oilseed you sell before it enters the 

processing operation. 

(iii) Oilseed destroyed by an event such as a 

process malfunction, fire, or natural 

disaster. 

(iv) Oilseed processed through operations prior to 

solvent extraction such as screening, 

dehulling, cracking, drying, and conditioning; 

but that are not routed to the solvent 

extractor for further processing. 

(v) Periodic physical measurements of inventory. 

For example, some sources periodically empty 

oilseed storage silos to physically measure 

the current oilseed inventory. This periodic 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

9-138 

measurement procedure typically results in a 

small inventory correction. The correction 

factor, usually less than 1 percent, may be 

used to make an adjustment to the source’s 

oilseed inventory that was estimated 

previously with indirect measurement 

techniques. To make this adjustment, your 

plan for demonstrating compliance must provide 

for such an adjustment. 

(b) Use Equation 1 of this section to determine the quantity 

of each oilseed type processed at your affected source 

during normal operating periods recorded within a calendar 

month. Equation 1 of this section follows:

of this section. 

SEEDE = Tons of oilseed in the inventory at the end of 

normal operating period “i” as determined in 

accordance with paragraph (a)(3) of this 

section. 

SEEDR = Tons of oilseed received during normal 

operating period “i” as determined in 

accordance with paragraph (a)(4) of this 

section. 

SEEDA = Tons of oilseed added or removed from the 

oilseed inventory during normal operating 

period “i” as determined in accordance with 

paragraph (a)(5) of this section. 

n = Number of normal operating periods in the 

calendar month during which this type oilseed 

was processed. 

(c) The quantity of each oilseed processed is the total tons 

of each type of listed oilseed processed during normal 

operating periods in the previous 12 operating months. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038

You determine the tons of each oilseed processed by 

summing the monthly quantity of each oilseed processed for 

the previous 12 operating months. You must record the 12 

operating months quantity of each type of oilseed 

processed by the end of each calendar month following an 

operating month. Use the 12 operating months quantity of 

each type of oilseed processed to determine the compliance 

ratio as described in Sec. 63.2840. The quantity of 

oilseed processed does not include oilseed processed 

during the operating status periods in paragraphs (c)(1) 

through (4) of this section: 

(1) Nonoperating periods as described in Sec. 63.2853 

(a)(2)(ii). 

(2) Initial startup periods as described in Sec. 

63.2850(c)(2) or (d)(2). 

(3) Malfunction periods as described in Sec. 

63.2850(e)(2). 

(4) Exempt operation periods as described in Sec. 63.2853 

(a)(2)(v). 

(5) If any one of these four operating status periods 

span an entire calendar month, then the calendar 

month is treated as a nonoperating month and there is 

no compliance ratio determination. 

Notifications, Reports, and Records 

Sec. 63.2860 What notifications must I submit and when? 

You must submit the one-time notifications listed in paragraphs 

(a) through (d) of this section to the responsible agency: 

(a) Initial notification for existing sources. For an 

existing source, submit an initial notification to the 

agency responsible for these NESHAP no later than 120 days 

after the effective date of this subpart. In the 

notification, include the items in paragraphs (a)(1) 

through (5) of this section: 

(1) The name and address of the owner or operator. 

(2) The physical address of the vegetable oil production 

process. 

(3) Identification of the relevant standard, such as the 

vegetable oil production NESHAP, and compliance date. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-140 

(4) A brief description of the source including the types 

of listed oilseeds processed, nominal operating 

capacity, and type of desolventizer(s) used. 

(5) A statement designating the source as a major source 

of HAP or a demonstration that the source meets the 

definition of an area source. An area source is a 

source that is not a major source and is not 

collocated within a plant site with other sources 

that are individually or collectively a major source. 

(b) Initial notifications for new and reconstructed sources. New 

or reconstructed sources must submit a series of notifications 

before, during, and after source construction per the schedule 

listed in Sec. 63.9. The information requirements for the 

notifications are the same as those listed in the General 

Provisions with the exceptions listed in paragraphs (b)(1) and 

(2) of this section: 

(1) The application for approval of construction does not 

require the specific HAP emission data required in 

Sec. 63.5(d)(1)(ii)(H) and (iii), (d)(2) and 

(d)(3)(ii). The application for approval of 

construction would include, instead, a brief 

description of the source including the types of 

listed oilseeds processed, nominal operating 

capacity, and type of desolventizer(s) used. 

(2) The notification of actual startup date must also 

include whether you have elected to operate under an 

initial startup period subject to Sec. 63.2850(c)(2) 

and provide an estimate and justification for the 

anticipated duration of the initial startup period. 

(c) Significant modification notifications. Any existing or 

new source that plans to undergo a significant 

modification as defined in Sec. 63.2872 must submit two 

reports as described in paragraphs (c)(1) and (2) of this 

section: 

(1) Initial notification. You must submit an initial 

notification to the agency responsible for these 

NESHAP 30 days prior to initial startup of the 

significantly modified source. The initial 

notification must demonstrate that the proposed 

changes qualify as a significant modification. The 

initial notification must include the items in 

paragraphs (c)(1)(i) and (ii) of this section: 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-141 

(i) The expected startup date of the modified 

source. 

(ii) A description of the significant modification 

including a list of the equipment that will be 

replaced or modified. If the significant 

modification involves changes other than 

adding or replacing extractors, desolventizertoasters (conventional and specialty), and 

meal dryer-coolers, then you must also include 

the fixed capital cost of the new components, 

expressed as a percentage of the fixed capital 

cost to build a comparable new vegetable oil 

production process; supporting documentation 

for the cost estimate; and documentation that 

the proposed changes will significantly affect 

solvent losses. 

(2) Notification of actual startup. You must submit a 

notification of actual startup date within 15 days 

after initial startup of the modified source. The 

notification must include the items in paragraphs 

(c)(2)(i) through (iv) of this section: 

(i) The initial startup date of the modified 

source. 

(ii) An indication whether you have elected to 

operate under an initial startup period 

subject to Sec. 63.2850(d)(2). 

(iii) The anticipated duration of any initial 

startup period. 

(iv) A justification for the anticipated duration 

of any initial startup period. 

(d) Notification of compliance status. As an existing, new, 

or reconstructed source, you must submit a notification of 

compliance status report to the responsible agency no 

later than 60 days after determining your initial 12 

operating months compliance ratio. If you are an existing 

source, you generally must submit this notification no 

later than 50 calendar months after the effective date of 

these NESHAP (36 calendar months for compliance, 12 

operating months to record data, and 2 calendar months to 

complete the report). If you are a new or reconstructed 

source, the notification of compliance status is generally 

due no later than 20 calendar months after initial startup 

(6 calendar months for the initial startup period, 12 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex

operating months to record data, and 2 calendar months to 

complete the report). The notification of compliance 

status must contain the items in paragraphs (d)(1) through 

(6) of this section: 

(1) The name and address of the owner or operator. 

(2) The physical address of the vegetable oil production 

process. 

(3) Each listed oilseed type processed during the 

previous 12 operating months. 

(4) Each HAP identified under Sec. 63.2854(a) as being

(a) Annual compliance certifications. The first annual 

compliance certification is due 12 calendar months after 

you submit the notification of compliance status. Each 

subsequent annual compliance certification is due 12 

calendar months after the previous annual compliance 

certification. The annual compliance certification 

provides the compliance status for each operating month 

during the 12 calendar months period ending 60 days prior 

to the date on which the report is due. Include the 

information in paragraphs (a)(1) through (6) of this 

section in the annual certification: 

(1) The name and address of the owner or operator. 

(2) The physical address of the vegetable oil production 

process. 

(3) Each listed oilseed type processed during the 12 

calendar months period covered by the report. 

(4) Each HAP identified under Sec. 63.2854(a) as being 

present in concentrations greater than 1 percent by 

volume in each delivery of solvent received during 

the 12 calendar months period covered by the report. 

(5) A statement designating the source as a major source 

of HAP or a demonstration that the source qualifies 

as an area source. An area source is a source that 

is not a major source and is not collocated within a 

plant site with other sources that are individually 

or collectively a major source. 

(6) A compliance certification to indicate whether the 

source was in compliance for each compliance 

determination made during the 12 calendar months 

period covered by the report. For each such 

compliance determination, you must include a 

certification of the items in paragraphs (a)(6)(i) 

through (ii) of this section: 

(i) You are following the procedures described in 

the plan for demonstrating compliance. 

(ii) The compliance ratio is less than or equal to 

1.00. 

(b) Deviation notification report. Submit a deviation report 

for each compliance determination you make in which the 

compliance ratio exceeds 1.00 as determined under Sec. 
CAAPP PERMIT

you choose to operate your source under an initial startup 

period subject to Sec. 63.2850(c)(2) or (d)(2) or a 

malfunction period subject to Sec. 63.2850(e)(2), you must 

submit a periodic SSM report by the end of the calendar 

month following each month in which the initial startup 

period or malfunction period occurred. The periodic SSM 

report must include the items in paragraphs (c)(1) through 

(3) of this section: 

(1) The name, title, and signature of a source’s 

responsible official who is certifying that the 

report accurately states that all actions taken 

during the initial startup or malfunction period were 

consistent with the SSM plan. 

(2) A description of events occurring during the time 

period, the date and duration of the events, and 

reason the time interval qualifies as an initial 

startup period or malfunction period. 

(3) An estimate of the solvent loss during the initial 

startup or malfunction period with supporting 

documentation. 

(d) Immediate SSM reports. If you handle a SSM during an 

initial startup period subject to Sec. 63.2850(c)(2) or

then you must submit an immediate SSM report. Immediate 

SSM reports consist of a telephone call or facsimile 

transmission to the responsible agency within 2 working 

days after starting actions inconsistent with the SSM 

plan, followed by a letter within 7 working days after the 

end of the event. The letter must include the items in 

paragraphs (d)(1) through (3) of this section: 

(1) The name, title, and signature of a source’s 

responsible official who is certifying the accuracy 

of the report, an explanation of the event, and the 

reasons for not following the SSM plan. 

(2) A description and date of the SSM event, its 

duration, and reason it qualifies as a SSM. 

(3) An estimate of the solvent loss for the duration of 

the SSM event with supporting documentation.

Sec. 63.2871 Who implements and enforces this subpart? 

(a) This subpart can be implemented by us, the U.S. EPA, or a 

delegated authority such as your State, local, or tribal 

agency. If the U.S. EPA Administrator has delegated 

authority to your State, local, or tribal agency, then 

that agency, as well as the U.S. EPA, has the authority to 

implement and enforce this subpart. You should contact 

your U.S. EPA Regional Office to find out if this subpart 

is delegated to your State, local, or tribal agency. 

(b) In delegating implementation and enforcement authority of 

this subpart to a State, local, or tribal agency under 

section 40 CFR part 63, subpart E, the authorities 

contained in paragraph (c) of this section are retained by 

the Administrator of the U.S. EPA and are not transferred 

to the State, local, or tribal agency. 

(c) The authorities that will not be delegated to State, 

local, or tribal agencies are as follows: 

(1) Approval of alternative nonopacity emissions 

standards under Sec. 63.6(g). 

(2) Approval of alternative opacity standards under Sec. 

63.6(h)(9). 

(3) Approval of major alternatives to test methods under 

Sec. 63.7(e)(2)(ii) and (f) and as defined in Sec. 

63.90. 

(4) Approval of major alternatives to monitoring under 

Sec. 63.8(f) and as defined in Sec. 63.90. 

(5) Approval of major alternatives to recordkeeping and 

reporting under Sec. 63.10(f) and as defined in Sec. 

63.90. 

Sec. 63.2872 What definitions apply to this subpart? 

Terms used in this subpart are defined in the sources listed: 

(a) The Clean Air Act, section 112(a). 

(b) In 40 CFR 63.2, the NESHAP General Provisions. 

(c) In this section as follows: 

Accounting month means a time interval defined by a 

business firm during which corporate economic and 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

9-155 

financial factors are determined on a consistent and 

regular basis. An accounting month will consist of 

approximately 4 to 5 calendar weeks and each accounting 

month will be of approximate equal duration. An 

accounting month may not correspond exactly to a calendar 

month, but 12 accounting months will correspond exactly to 

a calendar year. 

Actual solvent loss means the gallons of solvent lost from 

a source during 12 operating months as determined in 

accordance with Sec. 63.2853. 

Agricultural product means any commercially grown plant or 

plant product. 

Allowable HAP loss means the gallons of HAP that would 

have been lost from a source if the source was operating 

at the solvent loss factor for each listed oilseed type. 

The allowable HAP loss in gallons is determined by 

multiplying the tons of each oilseed type processed during 

the previous 12 operating months, as determined in 

accordance with Sec. 63.2855, by the corresponding oilseed 

solvent loss factor (gal/ton) listed in Table 1 of Sec. 

63.2840, and by the dimensionless constant 0.64, and 

summing the result for all oilseed types processed. 

Area source means any source that does not meet the major 

source definition. 

As received is the basis upon which all oilseed 

measurements must be determined and refers to the oilseed 

chemical and physical characteristics as initially 

received by the source and prior to any oilseed handling 

and processing. 

Batch operation means any process that operates in a 

manner where the addition of raw material and withdrawal 

of product do not occur simultaneously. Typically, raw 

material is added to a process, operational steps occur, 

and a product is removed from the process. More raw 

material is then added to the process and the cycle 

repeats. 

Calendar month means 1 month as specified in a calendar. 

Compliance date means the date on which monthly compliance 

recordkeeping begins. For existing sources, recordkeeping 

typically begins 3 years after the effective date of the 

subpart. For new and reconstructed sources, recordkeeping

typically begins upon initial startup, except as noted in 

Sec. 63.2834. 

Compliance ratio means a ratio of the actual HAP loss in 

gallons from the previous 12 operating months to an 

allowable HAP loss in gallons, which is determined by 

using oilseed solvent loss factors in Table 1 of Sec. 

63.2840, the weighted average volume fraction of HAP in 

solvent received for the previous 12 operating months, and 

the tons of each type of listed oilseed processed in the 

previous 12 operating months. Months during which no 

listed oilseed is processed, or months during which the 

Sec. 63.2850(c)(2) or (d)(2) initial startup period or the 

Sec. 63.2850(e)(2) malfunction period applies, are 

excluded from this calculation. Equation 2 of Sec. 

63.2840 is used to calculate this value. If the value is 

less than or equal to 1.00, the source is in compliance. 

If the value is greater than 1.00, the source is deviating 

from compliance. 

Continuous operation means any process that adds raw 

material and withdraws product simultaneously. Mass, 

temperature, concentration and other properties typically 

approach steady-state conditions. 

Conventional desolventizer means a desolventizer toaster 

that operates with indirect and direct-contact steam to 

remove solvent from the extracted meal. Oilseeds 

processed in a conventional desolventizer produce crude 

vegetable oil and crude meal products, such as animal 

feed. 

Corn germ dry milling means a source that processes corn 

germ that has been separated from the other corn 

components using a “dry” process of mechanical chafing and 

air sifting. 

Corn germ wet milling means a source that processes corn 

germ that has been separated from other corn components 

using a “wet” process of centrifuging a slurry steeped in 

a dilute sulfurous acid solution. 

Exempt period means a period of time during which a source 

processes agricultural products not defined as listed 

oilseed. 

Extraction solvent means an organic chemical medium used 

to remove oil from an oilseed. Typically, the extraction 

solvent is a commercial grade of hexane isomers which have 

an approximate HAP content of 64 percent by volume.

Hazardous air pollutant (HAP) means any substance or 

mixture of substances listed as a hazardous air pollutant 

under section 112(b) of the Clean Air Act, as of April 12, 

2001. 

Initial startup date means the first calendar day that a 

new, reconstructed or significantly modified source 

processes any listed oilseed. 

Initial startup period means a period of time from the 

initial startup date of a new, reconstructed or 

significantly modified source, for which you choose to 

operate the source under an initial startup period subject 

to Sec. 63.2850(c)(2) or (d)(2). During an initial 

startup period, a source is in compliance with the 

standards by following the operating and maintenance 

procedures listed for minimizing HAP emissions in the 

source’s SSM plan rather than being subject to a HAP 

emission limit. The initial startup period following 

initial startup of a new or reconstructed source may not 

exceed 6 calendar months. The initial startup period 

following a significant modification may not exceed 3 

calendar months. Solvent and oilseed inventory 

information recorded during the initial startup period is 

excluded from use in any compliance ratio determinations. 

Large cottonseed plant means a vegetable oil production 

process that processes 120,000 tons or more of cottonseed 

and other listed oilseed during all normal operating 

periods in a 12 operating months period used to determine 

compliance. 

Malfunction period means a period of time between the 

beginning and end of a process malfunction and the time 

reasonably necessary for a source to correct the 

malfunction for which you choose to operate the source 

under a malfunction period subject to Sec. 63.2850(e)(2). 

This period may include the duration of an unscheduled 

process shutdown, continued operation during a 

malfunction, or the subsequent process startup after a 

shutdown resulting from a malfunction. During a 

malfunction period, a source complies with the standards 

by following the operating and maintenance procedures 

described for minimizing HAP emissions in the source’s SSM 

plan rather than being subject to a HAP emission limit. 

Therefore, solvent and oilseed inventory information 

recorded during a malfunction period is excluded from use 

in any compliance ratio determinations.

9-158 

Mechanical extraction means removing vegetable oil from 

oilseeds using only mechanical devices such as presses or 

screws that physically force the oil from the oilseed. 

Mechanical extraction techniques use no organic solvents 

to remove oil from an oilseed. 

Nonoperating period means any period of time in which a 

source processes no agricultural product. This operating 

status does not apply during any period in which the 

source operates under an initial startup period as 

described in Sec. 63.2850(c)(2) or (d)(2), or a 

malfunction period, as described in Sec. 63.2850(e)(2). 

Normal operating period means any period of time in which 

a source processes a listed oilseed that is not 

categorized as an initial startup period as described in 

Sec. 63.2850(c)(2) or (d)(2), or a malfunction period, as 

described in Sec. 63.2850(e)(2). At the beginning and 

ending dates of a normal operating period, solvent and 

oilseed inventory information is recorded and included in 

the compliance ratio determination. 

Oilseed or listed oilseed means the following agricultural 

products: corn germ, cottonseed, flax, peanut, rapeseed 

(for example, canola), safflower, soybean, and sunflower. 

Oilseed solvent loss factor means a ratio expressed as 

gallons of solvent loss per ton of oilseed processed. The 

solvent loss factors are presented in Table 1 of Sec. 

63.2840 and are used to determine the allowable HAP loss. 

Operating month means any calendar or accounting month in 

which a source processes any quantity of listed oilseed, 

excluding any entire calendar or accounting month in which 

the source operated under an initial startup period as 

described in Sec. 63.2850(c)(2) or (d)(2), or a 

malfunction period as described in Sec. 63.2850(e)(2). An 

operating month may include time intervals characterized 

by several types of operating status. However, an 

operating month must have at least one normal operating 

period. 

Significant modification means the addition of new 

equipment or the modification of existing equipment that: 

(1) Significantly affects solvent losses from your 

vegetable oil production process; 

(2) The fixed capital cost of the new components 

represents a significant percentage of the fixed

capital cost of building a comparable new vegetable 

oil production process; 

(3) The fixed capital cost of the new equipment does not 

constitute reconstruction as defined in Sec. 63.2; 

and 

(4) Examples of significant modifications include 

replacement of or major changes to solvent recovery 

equipment such as extractors, desolventizertoasters/dryer-coolers, flash desolventizers, and 

distillation equipment associated with the mineral 

oil system, and equipment affecting desolventizing 

efficiency and steady-state operation of your 

vegetable oil production process such as flaking 

mills, oilseed heating and conditioning equipment, 

and cracking mills. 

Small cottonseed plant means a vegetable oil 

production process that processes less than 120,000 

tons of cottonseed and other listed oilseed during 

all normal operating periods in a 12 operating months 

period used to determine compliance. 

Solvent extraction means removing vegetable oil from 

listed oilseed using an organic solvent in a directcontact system. 

Solvent working capacity means the volume of 

extraction solvent normally retained in solvent 

recovery equipment. Examples include components such 

as the solvent extractor, desolventizer-toaster, 

solvent storage and working tanks, mineral oil 

absorption system, condensers, and oil/solvent 

distillation system. 

Specialty desolventizer means a desolventizer that 

removes excess solvent from soybean meal using vacuum 

conditions, energy from superheated solvent vapors, 

or reduced operating conditions (e.g., temperature) 

as compared to the typical operation of a 

conventional desolventizer. Soybeans processed in a 

specialty desolventizer result in high-protein 

vegetable meal products for human and animal 

consumption, such as calf milk replacement products 

and meat extender products. 

Vegetable oil production process means the equipment 

comprising a continuous process for producing crude 

vegetable oil and meal products, including specialty 
CAAPP PERMIT

soybean products, in which oil is removed from listed 

oilseeds through direct contact with an organic 

solvent. Process equipment typically includes the 

following components: oilseed preparation operations 

(including conditioning, drying, dehulling, and 

cracking), solvent extractors, desolventizertoasters, meal dryers, meal coolers, meal conveyor 

systems, oil distillation units, solvent evaporators 

and condensers, solvent recovery system (also 

referred to as a mineral oil absorption system), 

vessels storing solvent-laden materials, and crude 

meal packaging and storage vessels. A vegetable oil 

production process does not include vegetable oil 

refining operations (including operations such as 

bleaching, hydrogenation, and deodorizing) and 

operations that engage in additional chemical 

treatment of crude soybean meals produced in 

specialty desolventizer units (including operations 

such as soybean isolate production).

applicable State or local requirement, or (2) prevent the 

Administrator from implementing or enforcing any provision 

of this part or taking any other action authorized by the 

Act.

Date 

(e) (1) Notwithstanding the frequency of reporting 

requirements specified in paragraph (c) of this 

section, an owner or operator who is required by an 

applicable subpart to submit excess emissions and 

monitoring systems performance reports (and summary 

reports) on a quarterly (or more frequent) basis may 

reduce the frequency of reporting for that standard 

to semiannual if the following conditions are met: 

(i) For 1 full year (e.g., 4 quarterly or 12 

monthly reporting periods) the affected 

facility’s excess emissions and monitoring 

systems reports submitted to comply with a 

standard under this part continually 

demonstrate that the facility is in compliance 

with the applicable standard; 

(ii) The owner or operator continues to comply with 

all recordkeeping and monitoring requirements 

specified in this subpart and the applicable 

standard; and 

(iii) The Administrator does not object to a reduced 

frequency of reporting for the affected 

facility, as provided in paragraph (e)(2) of 

this section. 

(2) The frequency of reporting of excess emissions and 

monitoring systems performance (and summary) reports 

may be reduced only after the owner or operator 

notifies the Administrator in writing of his or her 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-15 

intention to make such a change and the Administrator 

does not object to the intended change. In deciding 

whether to approve a reduced frequency of reporting, 

the Administrator may review information concerning 

the source’s entire previous performance history 

during the required recordkeeping period prior to the 

intended change, including performance test results, 

monitoring data, and evaluations of an owner or 

operator’s conformance with operation and maintenance 

requirements. Such information may be used by the 

Administrator to make a judgment about the source’s 

potential for noncompliance in the future. If the 

Administrator disapproves the owner or operator’s 

request to reduce the frequency of reporting, the 

Administrator will notify the owner or operator in 

writing within 45 days after receiving notice of the 

owner or operator’s intention. The notification from 

the Administrator to the owner or operator will 

specify the grounds on which the disapproval is 

based. In the absence of a notice of disapproval 

within 45 days, approval is automatically granted. 

(3) As soon as monitoring data indicate that the affected 

facility is not in compliance with any emission 

limitation or operating parameter specified in the 

applicable standard, the frequency of reporting shall 

revert to the frequency specified in the applicable 

standard, and the owner or operator shall submit an 

excess emissions and monitoring systems performance 

report (and summary report, if required) at the next 

appropriate reporting period following the 

noncomplying event. After demonstrating compliance 

with the applicable standard for another full year, 

the owner or operator may again request approval from 

the Administrator to reduce the frequency of 

reporting for that standard as provided for in 

paragraphs (e)(1) and (e)(2) of this section. 

(f) Any owner or operator subject to the provisions of this 

part shall maintain a file of all measurements, including 

continuous monitoring system, monitoring device, and 

performance testing measurements; all continuous 

monitoring system performance evaluations; all continuous 

monitoring system or monitoring device calibration checks; 

adjustments and maintenance performed on these systems or 

devices; and all other information required by this part 

recorded in a permanent form suitable for inspection. The 

file shall be retained for at least two years following 

the date of such measurements, maintenance, reports, and 

records, except as follows:

(1) This paragraph applies to owners or operators 

required to install a continuous emissions monitoring 

system (CEMS) where the CEMS installed is automated, 

and where the calculated data averages do not exclude 

periods of CEMS breakdown or malfunction. An 

automated CEMS records and reduces the measured data 

to the form of the pollutant emission standard 

through the use of a computerized data acquisition 

system. In lieu of maintaining a file of all CEMS 

sub hourly measurements as required under paragraph 

(f) of this section, the owner or operator shall 

retain the most recent consecutive three averaging 

periods of sub hourly measurements and a file that 

contains a hard copy of the data acquisition system 

algorithm used to reduce the measured data into the 

reportable form of the standard. 

(2) This paragraph applies to owners or operators 

required to install a CEMS where the measured data is 

manually reduced to obtain the reportable form of the 

standard, and where the calculated data averages do 

not exclude periods of CEMS breakdown or malfunction. 

In lieu of maintaining a file of all CEMS sub hourly 

measurements as required under paragraph (f) of this 

section, the owner or operator shall retain all sub 

hourly measurements for the most recent reporting 

period. The sub hourly measurements shall be 

retained for 120 days from the date of the most 

recent summary or excess emission report submitted to 

the Administrator. 

(3) The Administrator or delegated authority, upon 

notification to the source, may require the owner or 

operator to maintain all measurements as required by 

paragraph (f) of this section, if the Administrator 

or the delegated authority determines these records 

are required to more accurately assess the compliance 

status of the affected source. 

(g) If notification substantially similar to that in paragraph 

(a) of this section is required by any other State or 

local agency, sending the Administrator a copy of that 

notification will satisfy the requirements of paragraph 

(a) of this section. 

(h) Individual subparts of this part may include specific 

provisions which clarify or make inapplicable the 

provisions set forth in this section.

Sec. 60.8 Performance tests. 

(a) Within 60 days after achieving the maximum production rate 

at which the affected facility will be operated, but not 

later than 180 days after initial startup of such facility 

and at such other times as may be required by the 

Administrator under section 114 of the Act, the owner or 

operator of such facility shall conduct performance 

test(s) and furnish the Administrator a written report of 

the results of such performance test(s). 

(b) Performance tests shall be conducted and data reduced in 

accordance with the test methods and procedures contained 

in each applicable subpart unless the Administrator (1) 

specifies or approves, in specific cases, the use of a 

reference method with minor changes in methodology, (2) 

approves the use of an equivalent method, (3) approves the 

use of an alternative method the results of which he has 

determined to be adequate for indicating whether a 

specific source is in compliance, (4) waives the 

requirement for performance tests because the owner or 

operator of a source has demonstrated by other means to 

the Administrator’s satisfaction that the affected 

facility is in compliance with the standard, or (5) 

approves shorter sampling times and smaller sample volumes 

when necessitated by process variables or other factors. 

Nothing in this paragraph shall be construed to abrogate 

the Administrator’s authority to require testing under 

section 114 of the Act. 

(c) Performance tests shall be conducted under such conditions 

as the Administrator shall specify to the plant operator 

based on representative performance of the affected 

facility. The owner or operator shall make available to 

the Administrator such records as may be necessary to 

determine the conditions of the performance tests. 

Operations during periods of startup, shutdown, and 

malfunction shall not constitute representative conditions 

for the purpose of a performance test nor shall emissions 

in excess of the level of the applicable emission limit 

during periods of startup, shutdown, and malfunction be 

considered a violation of the applicable emission limit 

unless otherwise specified in the applicable standard.

(d) The owner or operator of an affected facility shall 

provide the Administrator at least 30 days prior notice of 

any performance test, except as specified under other 

subparts, to afford the Administrator the opportunity to 

have an observer present. If after 30 days notice for an 

initially scheduled performance test, there is a delay 

(due to operational problems, etc.) in conducting the 

scheduled performance test, the owner or operator of an 

affected facility shall notify the Administrator (or 

delegated State or local agency) as soon as possible of 

any delay in the original test date, either by providing 

at least 7 days prior notice of the rescheduled date of 

the performance test, or by arranging a rescheduled date 

with the Administrator (or delegated State or local 

agency) by mutual agreement. 

(e) The owner or operator of an affected facility shall 

provide, or cause to be provided, performance testing 

facilities as follows: 

(1) Sampling ports adequate for test methods applicable 

to such facility. This includes (i) constructing the 

air pollution control system such that volumetric 

flow rates and pollutant emission rates can be 

accurately determined by applicable test methods and 

procedures and (ii) providing a stack or duct free of 

cyclonic flow during performance tests, as 

demonstrated by applicable test methods and 

procedures. 

(2) Safe sampling platform(s). 

(3) Safe access to sampling platform(s). 

(4) Utilities for sampling and testing equipment. 

(f) Unless otherwise specified in the applicable subpart, each 

performance test shall consist of three separate runs 

using the applicable test method. Each run shall be 

conducted for the time and under the conditions specified 

in the applicable standard. For the purpose of 

determining compliance with an applicable standard, the 

arithmetic means of results of the three runs shall apply. 

In the event that a sample is accidentally lost or 

conditions occur in which one of the three runs must be 

discontinued because of forced shutdown, failure of an 

irreplaceable portion of the sample train, extreme 

meteorological conditions, or other circumstances, beyond 

the owner or operator’s control, compliance may, upon the 
CAAPP PERMIT

Sec. 60.9 Availability of information. 

The availability to the public of information provided to, or 

otherwise obtained by, the Administrator under this part shall be 

governed by part 2 of this chapter. (Information submitted 

voluntarily to the Administrator for the purposes of Secs. 60.5 

and 60.6 is governed by Secs. 2.201 through 2.213 of this chapter 

and not by Sec. 2.301 of this chapter.) 

Sec. 60.10 State authority. 

The provisions of this part shall not be construed in any manner 

to preclude any State or political subdivision thereof from: 

(a) Adopting and enforcing any emission standard or limitation 

applicable to an affected facility, provided that such 

emission standard or limitation is not less stringent than 

the standard applicable to such facility. 

(b) Requiring the owner or operator of an affected facility to 

obtain permits, licenses, or approvals prior to initiating 

construction, modification, or operation of such facility. 

Sec. 60.11 Compliance with standards and maintenance 

requirements. 

(a) Compliance with standards in this part, other than opacity 

standards, shall be determined in accordance with 

performance tests established by Sec. 60.8, unless 

otherwise specified in the applicable standard. 

(b) Compliance with opacity standards in this part shall be 

determined by conducting observations in accordance with 

Method 9 in appendix A of this part, any alternative 

method that is approved by the Administrator, or as 

provided in paragraph (e)(5) of this section. For 

purposes of determining initial compliance, the minimum 

total time of observations shall be 3 hours (30 6-minute 

averages) for the performance test or other set of 

observations (meaning those fugitive-type emission sources 

subject only to an opacity standard). 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-20 

(c) The opacity standards set forth in this part shall apply 

at all times except during periods of startup, shutdown, 

malfunction, and as otherwise provided in the applicable 

standard. 

(d) At all times, including periods of startup, shutdown, and 

malfunction, owners and operators shall, to the extent 

practicable, maintain and operate any affected facility 

including associated air pollution control equipment in a 

manner consistent with good air pollution control practice 

for minimizing emissions. Determination of whether 

acceptable operating and maintenance procedures are being 

used will be based on information available to the 

Administrator which may include, but is not limited to, 

monitoring results, opacity observations, review of 

operating and maintenance procedures, and inspection of 

the source. 

(e) (1) For the purpose of demonstrating initial compliance, 

opacity observations shall be conducted concurrently 

with the initial performance test required in Sec. 

60.8 unless one of the following conditions apply. 

If no performance test under Sec. 60.8 is required, 

then opacity observations shall be conducted within 

60 days after achieving the maximum production rate 

at which the affected facility will be operated but 

no later than 180 days after initial startup of the 

facility. If visibility or other conditions prevent 

the opacity observations from being conducted 

concurrently with the initial performance test 

required under Sec. 60.8, the source owner or 

operator shall reschedule the opacity observations as 

soon after the initial performance test as possible, 

but not later than 30 days thereafter, and shall 

advise the Administrator of the rescheduled date. In 

these cases, the 30-day prior notification to the 

Administrator required in Sec. 60.7(a)(6) shall be 

waived. The rescheduled opacity observations shall 

be conducted (to the extent possible) under the same 

operating conditions that existed during the initial 

performance test conducted under Sec. 60.8. The 

visible emissions observer shall determine whether 

visibility or other conditions prevent the opacity 

observations from being made concurrently with the 

initial performance test in accordance with 

procedures contained in Method 9 of appendix B of 

this part. Opacity readings of portions of plumes 

which contain condensed, uncombined water vapor shall 

not be used for purposes of determining compliance 

with opacity standards. The owner or operator of an 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-21 

affected facility shall make available, upon request 

by the Administrator, such records as may be 

necessary to determine the conditions under which the 

visual observations were made and shall provide 

evidence indicating proof of current visible observer 

emission certification. Except as provided in 

paragraph (e)(5) of this section, the results of 

continuous monitoring by transmissometer which 

indicate that the opacity at the time visual 

observations were made was not in excess of the 

standard are probative but not conclusive evidence of 

the actual opacity of an emission, provided that the 

source shall meet the burden of proving that the 

instrument used meets (at the time of the alleged 

violation) Performance Specification 1 in appendix B 

of this part, has been properly maintained and (at 

the time of the alleged violation) that the resulting 

data have not been altered in any way. 

(2) Except as provided in paragraph (e)(3) of this 

section, the owner or operator of an affected 

facility to which an opacity standard in this part 

applies shall conduct opacity observations in 

accordance with paragraph (b) of this section, shall 

record the opacity of emissions, and shall report to 

the Administrator the opacity results along with the 

results of the initial performance test required 

under Sec. 60.8. The inability of an owner or 

operator to secure a visible emissions observer shall 

not be considered a reason for not conducting the 

opacity observations concurrent with the initial 

performance test. 

(3) The owner or operator of an affected facility to 

which an opacity standard in this part applies may 

request the Administrator to determine and to record 

the opacity of emissions from the affected facility 

during the initial performance test and at such times 

as may be required. The owner or operator of the 

affected facility shall report the opacity results. 

Any request to the Administrator to determine and to 

record the opacity of emissions from an affected 

facility shall be included in the notification 

required in Sec. 60.7(a)(6). If, for some reason, 

the Administrator cannot determine and record the 

opacity of emissions from the affected facility 

during the performance test, then the provisions of 

paragraph (e)(1) of this section shall apply.

(4) An owner or operator of an affected facility using a 

continuous opacity monitor (transmissometer) shall 

record the monitoring data produced during the 

initial performance test required by Sec. 60.8 and 

shall furnish the Administrator a written report of 

the monitoring results along with Method 9 and Sec. 

60.8 performance test results. 

(5) An owner or operator of an affected facility subject 

to an opacity standard may submit, for compliance 

purposes, continuous opacity monitoring system (COMS) 

data results produced during any performance test 

required under Sec. 60.8 in lieu of Method 9 

observation data. If an owner or operator elects to 

submit COMS data for compliance with the opacity 

standard, he shall notify the Administrator of that 

decision, in writing, at least 30 days before any 

performance test required under Sec. 60.8 is 

conducted. Once the owner or operator of an affected 

facility has notified the Administrator to that 

effect, the COMS data results will be used to 

determine opacity compliance during subsequent tests 

required under Sec. 60.8 until the owner or operator 

notifies the Administrator, in writing, to the 

contrary. For the purpose of determining compliance 

with the opacity standard during a performance test 

required under Sec. 60.8 using COMS data, the minimum 

total time of COMS data collection shall be averages 

of all 6-minute continuous periods within the 

duration of the mass emission performance test. 

Results of the COMS opacity determinations shall be 

submitted along with the results of the performance 

test required under Sec. 60.8. The owner or operator 

of an affected facility using a COMS for compliance 

purposes is responsible for demonstrating that the 

COMS meets the requirements specified in Sec. 

60.13(c) of this part, that the COMS has been 

properly maintained and operated, and that the 

resulting data have not been altered in any way. If 

COMS data results are submitted for compliance with 

the opacity standard for a period of time during 

which Method 9 data indicates noncompliance, the 

Method 9 data will be used to determine compliance 

with the opacity standard. 

(6) Upon receipt from an owner or operator of the written 

reports of the results of the performance tests 

required by Sec. 60.8, the opacity observation 

results and observer certification required by Sec. 

60.11(e)(1), and the COMS results, if applicable, the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-23 

Administrator will make a finding concerning 

compliance with opacity and other applicable 

standards. If COMS data results are used to comply 

with an opacity standard, only those results are 

required to be submitted along with the performance 

test results required by Sec. 60.8. If the 

Administrator finds that an affected facility is in 

compliance with all applicable standards for which 

performance tests are conducted in accordance with 

Sec. 60.8 of this part but during the time such 

performance tests are being conducted fails to meet 

any applicable opacity standard, he shall notify the 

owner or operator and advise him that he may petition 

the Administrator within 10 days of receipt of 

notification to make appropriate adjustment to the 

opacity standard for the affected facility. 

(7) The Administrator will grant such a petition upon a 

demonstration by the owner or operator that the 

affected facility and associated air pollution 

control equipment was operated and maintained in a 

manner to minimize the opacity of emissions during 

the performance tests; that the performance tests 

were performed under the conditions established by 

the Administrator; and that the affected facility and 

associated air pollution control equipment were 

incapable of being adjusted or operated to meet the 

applicable opacity standard. 

(8) The Administrator will establish an opacity standard 

for the affected facility meeting the above 

requirements at a level at which the source will be 

able, as indicated by the performance and opacity 

tests, to meet the opacity standard at all times 

during which the source is meeting the mass or 

concentration emission standard. The Administrator 

will promulgate the new opacity standard in the 

Federal Register. 

(f) Special provisions set forth under an applicable subpart

shall supersede any conflicting provisions in paragraphs 

(a) through (e) of this section.

Sec. 60.12 Circumvention. 

No owner or operator subject to the provisions of this part shall 

build, erect, install, or use any article, machine, equipment or 

process, the use of which conceals an emission which would 

otherwise constitute a violation of an applicable standard. Such 

concealment includes, but is not limited to, the use of gaseous 

diluents to achieve compliance with an opacity standard or with a 

standard which is based on the concentration of a pollutant in 

the gases discharged to the atmosphere. 

[39 FR 9314, Mar. 8, 1974] 

Sec. 60.13 Monitoring requirements. 

(a) For the purposes of this section, all continuous 

monitoring systems required under applicable subparts 

shall be subject to the provisions of this section upon 

promulgation of performance specifications for continuous 

monitoring systems under appendix B to this part and, if 

the continuous monitoring system is used to demonstrate 

compliance with emission limits on a continuous basis, 

appendix F to this part, unless otherwise specified in an 

applicable subpart or by the Administrator. Appendix F is 

applicable December 4, 1987. 

(b) All continuous monitoring systems and monitoring devices 

shall be installed and operational prior to conducting 

performance tests under Sec. 60.8. Verification of 

operational status shall, as a minimum, include completion 

of the manufacturer’s written requirements or 

recommendations for installation, operation, and 

calibration of the device. 

(c) If the owner or operator of an affected facility elects to 

submit continuous opacity monitoring system (COMS) data 

for compliance with the opacity standard as provided under 

Sec. 60.11(e)(5), he shall conduct a performance 

evaluation of the COMS as specified in Performance 

Specification 1, appendix B, of this part before the 

performance test required under Sec. 60.8 is conducted. 
CAAPP PERMIT

I.D. Number: 115015AAE 

Application No.: 96030038 

10-25 

Otherwise, the owner or operator of an affected facility 

shall conduct a performance evaluation of the COMS or 

continuous emission monitoring system (CEMS) during any 

performance test required under Sec. 60.8 or within 30 

days thereafter in accordance with the applicable 

performance specification in appendix B of this part, The 

owner or operator of an affected facility shall conduct 

COMS or CEMS performance evaluations at such other times 

as may be required by the Administrator under section 114 

of the Act. 

(1) The owner or operator of an affected facility using a 

COMS to determine opacity compliance during any 

performance test required under Sec. 60.8 and as 

described in Sec. 60.11(e)(5) shall furnish the 

Administrator two or, upon request, more copies of a 

written report of the results of the COMS performance 

evaluation described in paragraph (c) of this section 

at least 10 days before the performance test required 

under Sec. 60.8 is conducted. 

(2) Except as provided in paragraph (c)(1) of this 

section, the owner or operator of an affected 

facility shall furnish the Administrator within 60 

days of completion two or, upon request, more copies 

of a written report of the results of the performance 

evaluation. 

(d) (1) Owners and operators of a CEMS installed in 

accordance with the provisions of this part, must 

automatically check the zero (or low level value 

between 0 and 20 percent of span value) and span (50 

to 100 percent of span value) calibration drifts at 

least once daily in accordance with a written 

procedure. The zero and span must, as a minimum, be 

adjusted whenever either the 24-hour zero drift or 

the 24-hour span drift exceeds two times the limit of 

the applicable performance specification in appendix 

B of this part. The system must allow the amount of 

the excess zero and span drift to be recorded and 

quantified whenever specified. Owners and operators 

of a COMS installed in accordance with the provisions 

of this part, must automatically, intrinsic to the 

opacity monitor, check the zero and upscale (span) 

calibration drifts at least once daily. For a 

particular COMS, the acceptable range of zero and 

upscale calibration materials is as defined in the 

applicable version of PS-1 in appendix B of this 

part. For continuous monitoring systems measuring 

opacity of emissions not using automatic zero

adjustments, the optical surfaces exposed to the 

effluent gases shall be cleaned prior to performing 

the zero and span drift adjustments. For systems 

using automatic zero adjustments, the optical 

surfaces shall be cleaned when the cumulative 

automatic zero compensation exceeds 4 percent 

opacity. 

(2) Unless otherwise approved by the Administrator, the 

following procedures must be followed for a COMS. 

Minimum procedures must include an automated method 

for producing a simulated zero opacity condition and 

an upscale opacity condition using a certified 

neutral density filter or other related technique to 

produce a known obstruction of the light beam. Such 

procedures must provide a system check of all active 

analyzer internal optics with power or curvature, all 

active electronic circuitry including the light 

source and photodetector assembly, and electronic or 

electro-mechanical systems and hardware and or 

software used during normal measurement operation. 

(e) Except for system breakdowns, repairs, calibration checks, 

and zero and span adjustments required under paragraph (d) 

of this section, all continuous monitoring systems shall 

be in continuous operation and shall meet minimum 

frequency of operation requirements as follows: 

(1) All continuous monitoring systems referenced by 

paragraph (c) of this section for measuring opacity 

of emissions shall complete a minimum of one cycle of 

sampling and analyzing for each successive 10-second 

period and one cycle of data recording for each 

successive 6-minute period. 

(2) All continuous monitoring systems referenced by 

paragraph (c) of this section for measuring 

emissions, except opacity, shall complete a minimum 

of one cycle of operation (sampling, analyzing, and 

data recording) for each successive 15-minute period. 

(f) All continuous monitoring systems or monitoring devices 

shall be installed such that representative measurements 

of emissions or process parameters from the affected 

facility are obtained. Additional procedures for location 

of continuous monitoring systems contained in the 

applicable Performance Specifications of appendix B of 

this part shall be used.

Application No.: 96030038 

10-27 

(g) (1) When more than one continuous monitoring system is 

used to measure the emissions from only one affected 

facility (e.g., multiple breechings, multiple 

outlets), the owner or operator shall report the 

results as required from each continuous monitoring 

system. When the effluent from one affected facility 

is released to the atmosphere through more than one 

point, the owner or operator shall install an 

applicable continuous monitoring system on each 

separate effluent unless installation of fewer 

systems is approved by the Administrator. 

(2) When the effluents from two or more affected 

facilities subject to the same opacity standard are 

combined before being released to the atmosphere, the 

owner or operator may either install a continuous 

opacity monitoring system at a location monitoring 

the combined effluent or install an opacity combiner 

system comprised of opacity and flow monitoring 

systems on each stream, and shall report as per Sec. 

60.7(c) on the combined effluent. When the affected 

facilities are not subject to the same opacity 

standard, the owner or operator shall report the 

results as per Sec. 60.7(c) on the combined effluent 

against the most stringent opacity standard 

applicable, except for documented periods of shutdown 

of the affected facility, subject to the most 

stringent opacity standard. During such times, the 

next most stringent opacity standard shall apply. 

(3) When the effluents from two or more affected 

facilities subject to the same emissions standard, 

other than opacity, are combined before being 

released to the atmosphere, the owner or operator may 

install applicable continuous emission monitoring 

systems on each effluent or on the combined effluent. 

The owner or operator may report the results as 

required for each affected facility or for the 

combined effluent. When the affected facilities are 

not subject to the same emissions standard, separate 

continuous emission monitoring systems shall be 

installed on each effluent and the owner or operator 

shall report as required for each affected facility. 

(h) Owners or operators of all continuous monitoring systems 

for measurement of opacity shall reduce all data to 6-

minute averages and for continuous monitoring systems 

other than opacity to 1-hour averages for time periods as 

defined in Sec. 60.2. Six-minute opacity averages shall 

be calculated from 36 or more data points equally spaced 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-28 

over each 6-minute period. For continuous monitoring 

systems other than opacity, 1-hour averages shall be 

computed from four or more data points equally spaced over 

each 1-hour period. Data recorded during periods of 

continuous system breakdown, repair, calibration checks, 

and zero and span adjustments shall not be included in the 

data averages computed under this paragraph. For owners 

and operators complying with the requirements in Sec. 

60.7(f) (1) or (2), data averages must include any data 

recorded during periods of monitor breakdown or 

malfunction. An arithmetic or integrated average of all 

data may be used. The data may be recorded in reduced or 

nonreduced form (e.g., ppm pollutant and percent O2 or 

ng/J of pollutant). All excess emissions shall be 

converted into units of the standard using the applicable 

conversion procedures specified in subparts. After 

conversion into units of the standard, the data may be 

rounded to the same number of significant digits as used 

in the applicable subparts to specify the emission limit 

(e.g., rounded to the nearest 1 percent opacity). 

(i) After receipt and consideration of written application, 

the Administrator may approve alternatives to any 

monitoring procedures or requirements of this part 

including, but not limited to the following: 

(1) Alternative monitoring requirements when installation 

of a continuous monitoring system or monitoring 

device specified by this part would not provide 

accurate measurements due to liquid water or other 

interferences caused by substances in the effluent 

gases. 

(2) Alternative monitoring requirements when the affected 

facility is infrequently operated. 

(3) Alternative monitoring requirements to accommodate 

continuous monitoring systems that require additional 

measurements to correct for stack moisture 

conditions. 

(4) Alternative locations for installing continuous 

monitoring systems or monitoring devices when the 

owner or operator can demonstrate that installation 

at alternate locations will enable accurate and 

representative measurements. 

(5) Alternative methods of converting pollutant 

concentration measurements to units of the standards. 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-29 

(6) Alternative procedures for performing daily checks of 

zero and span drift that do not involve use of span 

gases or test cells. 

(7) Alternatives to the A.S.T.M. test methods or sampling 

procedures specified by any subpart. 

(8) Alternative continuous monitoring systems that do not 

meet the design or performance requirements in 

Performance Specification 1, appendix B, but 

adequately demonstrate a definite and consistent 

relationship between its measurements and the 

measurements of opacity by a system complying with 

the requirements in Performance Specification 1. The 

Administrator may require that such demonstration be 

performed for each affected facility. 

(9) Alternative monitoring requirements when the effluent 

from a single affected facility or the combined 

effluent from two or more affected facilities is 

released to the atmosphere through more than one 

point. 

(j) An alternative to the relative accuracy (RA) test 

specified in Performance Specification 2 of appendix B may 

be requested as follows: 

(1) An alternative to the reference method tests for 

determining RA is available for sources with emission 

rates demonstrated to be less than 50 percent of the 

applicable standard. A source owner or operator may 

petition the Administrator to waive the RA test in 

Section 8.4 of Performance Specification 2 and 

substitute the procedures in Section 16.0 if the 

results of a performance test conducted according to 

the requirements in Sec. 60.8 of this subpart or 

other tests performed following the criteria in Sec. 

60.8 demonstrate that the emission rate of the 

pollutant of interest in the units of the applicable 

standard is less than 50 percent of the applicable 

standard. For sources subject to standards expressed 

as control efficiency levels, a source owner or 

operator may petition the Administrator to waive the 

RA test and substitute the procedures in Section 16.0 

of Performance Specification 2 if the control device 

exhaust emission rate is less than 50 percent of the 

level needed to meet the control efficiency 

requirement. The alternative procedures do not apply 

if the continuous emission monitoring system is used 

to determine compliance continuously with the 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-30 

applicable standard. The petition to waive the RA 

test shall include a detailed description of the 

procedures to be applied. Included shall be location 

and procedure for conducting the alternative, the 

concentration or response levels of the alternative 

RA materials, and the other equipment checks included 

in the alternative procedure. The Administrator will 

review the petition for completeness and 

applicability. The determination to grant a waiver 

will depend on the intended use of the CEMS data 

(e.g., data collection purposes other than NSPS) and 

may require specifications more stringent than in 

Performance Specification 2 (e.g., the applicable 

emission limit is more stringent than NSPS). 

(2) The waiver of a CEMS RA test will be reviewed and may 

be rescinded at such time, following successful 

completion of the alternative RA procedure, that the 

CEMS data indicate that the source emissions are 

approaching the level. The criterion for reviewing 

the waiver is the collection of CEMS data showing that 

emissions have exceeded 70 percent of the applicable 

standard for seven, consecutive, averaging periods as 

specified by the applicable regulation(s). For 

sources subject to standards expressed as control 

efficiency levels, the criterion for reviewing the 

waiver is the collection of CEMS data showing that 

exhaust emissions have exceeded 70 percent of the 

level needed to meet the control efficiency 

requirement for seven, consecutive, averaging periods 

as specified by the applicable regulation(s) [e.g., 

Sec. 60.45(g) (2) and (3), Sec. 60.73(e), and Sec. 

60.84(e)]. It is the responsibility of the source 

operator to maintain records and determine the level 

of emissions relative to the criterion on the waiver 

of RA testing. If this criterion is exceeded, the 

owner or operator must notify the Administrator within 

10 days of such occurrence and include a description 

of the nature and cause of the increasing emissions. 

The Administrator will review the notification and may 

rescind the waiver and require the owner or operator 

to conduct a RA test of the CEMS as specified in 

Section 8.4 of Performance Specification 2.

Editorial Note: At 65 FR 61749, Oct. 17, 2000, Sec. 60.13 was 

amended by revising the words “ng/J of pollutant” to read “ng of 

pollutant per J of heat input” in the sixth sentence of paragraph 

(h). However, the amendment could not be incorporated because 

the words “ng/J of pollutant” do not exist in the sixth sentence 

of paragraph (h). 

Sec. 60.14 Modification. 

(a) Except as provided under paragraphs (e) and (f) of this 

section, any physical or operational change to an existing 

facility which results in an increase in the emission rate 

to the atmosphere of any pollutant to which a standard 

applies shall be considered a modification within the 

meaning of section 111 of the Act. Upon modification, an 

existing facility shall become an affected facility for 

each pollutant to which a standard applies and for which 

there is an increase in the emission rate to the 

atmosphere. 

(b) Emission rate shall be expressed as kg/hr of any pollutant 

discharged into the atmosphere for which a standard is 

applicable. The Administrator shall use the following to 

determine emission rate: 

(1) Emission factors as specified in the latest issue of 

“Compilation of Air Pollutant Emission Factors,” EPA 

Publication No. AP-42, or other emission factors 

determined by the Administrator to be superior to 

AP-42 emission factors, in cases where utilization of 

emission factors demonstrates that the emission level 

resulting from the physical or operational change 

will either clearly increase or clearly not increase. 

(2) Material balances, continuous monitor data, or manual 

emission tests in cases where utilization of emission 

factors as referenced in paragraph (b)(1) of this 

section does not demonstrate to the Administrator’s 

satisfaction whether the emission level resulting 

from the physical or operational change will either 

clearly increase or clearly not increase, or where an 

owner or operator demonstrates to the Administrator’s 

satisfaction that there are reasonable grounds to 

dispute the result obtained by the Administrator 

utilizing emission factors as referenced in paragraph 

(b)(1) of this section. When the emission rate is 

based on results from manual emission tests or 

continuous monitoring systems, the procedures 

specified in appendix C of this part shall be used to 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038 

10-32 

determine whether an increase in emission rate has 

occurred. Tests shall be conducted under such 

conditions as the Administrator shall specify to the 

owner or operator based on representative performance 

of the facility. At least three valid test runs must 

be conducted before and at least three after the 

physical or operational change. All operating 

parameters which may affect emissions must be held 

constant to the maximum feasible degree for all test 

runs. 

(c) The addition of an affected facility to a stationary 

source as an expansion to that source or as a replacement 

for an existing facility shall not by itself bring within 

the applicability of this part any other facility within 

that source. 

(d) [Reserved] 

(e) The following shall not, by themselves, be considered 

modifications under this part: 

(1) Maintenance, repair, and replacement which the 

Administrator determines to be routine for a source 

category, subject to the provisions of paragraph (c) 

of this section and Sec. 60.15. 

(2) An increase in production rate of an existing 

facility, if that increase can be accomplished 

without a capital expenditure on that facility. 

(3) An increase in the hours of operation. 

(4) Use of an alternative fuel or raw material if, prior 

to the date any standard under this part becomes 

applicable to that source type, as provided by Sec. 

60.1, the existing facility was designed to 

accommodate that alternative use. A facility shall 

be considered to be designed to accommodate an 

alternative fuel or raw material if that use could be 

accomplished under the facility’s construction 

specifications as amended prior to the change. 

Conversion to coal required for energy 

considerations, as specified in section 111(a)(8) of 

the Act, shall not be considered a modification. 

(5) The addition or use of any system or device whose 

primary function is the reduction of air pollutants, 

except when an emission control system is removed or 
CAAPP PERMIT

is replaced by a system which the Administrator 

determines to be less environmentally beneficial. 

(6) The relocation or change in ownership of an existing 

facility. 

(f) Special provisions set forth under an applicable subpart

of this part shall supersede any conflicting provisions of 

this section. 

(g) Within 180 days of the completion of any physical or 

operational change subject to the control measures 

specified in paragraph (a) of this section, compliance 

with all applicable standards must be achieved. 

(h) No physical change, or change in the method of operation, 

at an existing electric utility steam generating unit 

shall be treated as a modification for the purposes of 

this section provided that such change does not increase 

the maximum hourly emissions of any pollutant regulated 

under this section above the maximum hourly emissions 

achievable at that unit during the 5 years prior to the 

change. 

(i) Repowering projects that are awarded funding from the 

Department of Energy as permanent clean coal technology 

demonstration projects (or similar projects funded by EPA) 

are exempt from the requirements of this section provided 

that such change does not increase the maximum hourly 

emissions of any pollutant regulated under this section 

above the maximum hourly emissions achievable at that unit 

during the five years prior to the change. 

(j) (1) Repowering projects that qualify for an extension 

under section 409(b) of the Clean Air Act are 

exempt from the requirements of this section, 

provided that such change does not increase 

the actual hourly emissions of any pollutant 

regulated under this section above the actual 

hourly emissions achievable at that unit 

during the 5 years prior to the change. 

(2) This exemption shall not apply to any new unit that: 

(i) Is designated as a replacement for an existing 

unit; 

(ii) Qualifies under section 409(b) of the Clean 

Air Act for an extension of an emission

limitation compliance date under section 405 

of the Clean Air Act; and 

(iii) Is located at a different site than the 

existing unit. 

(k) The installation, operation, cessation, or removal of a 

temporary clean coal technology demonstration project is 

exempt from the requirements of this section. A temporary 

clean coal control technology demonstration project, for 

the purposes of this section is a clean coal technology 

demonstration project that is operated for a period of 5 

years or less, and which complies with the State 

implementation plan for the State in which the project is 

located and other requirements necessary to attain and 

maintain the national ambient air quality standards during 

the project and after it is terminated. 

(l) The reactivation of a very clean coal-fired electric 

utility steam generating unit is exempt from the 

requirements of this section.

Sec. 60.15 Reconstruction. 

(a) An existing facility, upon reconstruction, becomes an 

affected facility, irrespective of any change in emission 

rate. 

(b) “Reconstruction” means the replacement of components of an 

existing facility to such an extent that: 

(1) The fixed capital cost of the new components exceeds 

50 percent of the fixed capital cost that would be 

required to construct a comparable entirely new 

facility, and 

(2) It is technologically and economically feasible to 

meet the applicable standards set forth in this part. 

(c) “Fixed capital cost” means the capital needed to provide 

all the depreciable components. 

(d) If an owner or operator of an existing facility proposes 

to replace components, and the fixed capital cost of the 

new components exceeds 50 percent of the fixed capital 

cost that would be required to construct a comparable

of the proposed replacements. The notice must be 

postmarked 60 days (or as soon as practicable) before 

construction of the replacements is commenced and must 

include the following information: 

(1) Name and address of the owner or operator. 

(2) The location of the existing facility. 

(3) A brief description of the existing facility and the 

components which are to be replaced. 

(4) A description of the existing air pollution control 

equipment and the proposed air pollution control 

equipment. 

(5) An estimate of the fixed capital cost of the

(e) The Administrator will determine, within 30 days of the 

receipt of the notice required by paragraph (d) of this 

section and any additional information he may reasonably 

require, whether the proposed replacement constitutes 

reconstruction. 

(f) The Administrator’s determination under paragraph (e) 

shall be based on: 

(1) The fixed capital cost of the replacements in 

comparison to the fixed capital cost that would be 

required to construct a comparable entirely new 

facility; 

(2) The estimated life of the facility after the 

replacements compared to the life of a comparable 

entirely new facility; 

(3) The extent to which the components being replaced 

cause or contribute to the emissions from the 

facility; and

procedures for sulfur dioxide. 

(a) Except as provided in paragraphs (g) and (h) of this 

section and in § 60.8(b), performance tests required under 

§ 60.8 shall be conducted following the procedures 

specified in paragraphs (b), (c), (d), (e), and (f) of 

this section, as applicable. Section 60.8(f) does not 

apply to this section. The 30-day notice required in 

§ 60.8(d) applies only to the initial performance test 

unless otherwise specified by the Administrator. 

(b) The initial performance test required under § 60.8 shall 

be conducted over 30 consecutive operating days of the 

steam generating unit. Compliance with the percent 

reduction requirements and SO2 emission limits under 

§ 60.42c shall be determined using a 30-day average. The 

first operating day included in the initial performance 

test shall be scheduled within 30 days after achieving the 

maximum production rate at which the affect facility will 

be operated, but not later than 180 days after the initial 

startup of the facility. The steam generating unit load 

during the 30-day period does not have to be the maximum 

design heat input capacity, but must be representative of 

future operating conditions. 

(c) After the initial performance test required under 

paragraph (b) and § 60.8, compliance with the percent 

reduction requirements and SO2 emission limits under 

§ 60.42c is based on the average percent reduction and the 

average S02 emission rates for 30 consecutive steam 

generating unit operating days. A separate performance 

test is completed at the end of each steam generating unit 

operating day, and a new 30-day average percent reduction

and SO2 emission rate are calculated to show compliance 

with the standard. 

(d) If only coal, only oil, or a mixture of coal and oil is 

combusted in an affected facility, the procedures in 

Method 19 are used to determine the hourly SO2 emission 

rate (Eho) and the 30-day average SO2 emission rate (Eao). 

The hourly averages used to compute the 30-day averages 

are obtained from the continuous emission monitoring 

system (CEMS). Method 19 shall be used to calculate Eao

when using daily fuel sampling or Method 6B. 

(e) If coal, oil, or coal and oil are combusted with other 

fuels: 

(1) An adjusted Eho (Ehoo

) is used in Equation 19-19 of 

Method 19 to compute the adjusted Eao (Eaoo

). The Ehoo 

is computed using the following formula: 

Ehoo

 = [Eho − Ew(1 − Xk)]/Xk

Where: 

Ehoo

 Is the adjusted Eho, ng/J (lb/million Btu) 

Eho Is the hourly SO2 emission rate, ng/J 

(lb/million Btu) 

Ew Is the SO2 concentration in fuels other than 

coal and oil combusted in the affected 

facility, as determined by fuel sampling and 

analysis procedures in Method 9, ng/J 

(lb/million Btu). The value Ew for each fuel 

lot is used for each hourly average during the 

time that the lot is being combusted. The 

owner or operator does not have to measure Ew

if the owner or operator elects to assume Ew = 

0. 

Xk Is the fraction of the total heat input from 

fuel combustion derived from coal and oil, as 

determined by applicable procedures in Method 

19. 

(2) The owner or operator of an affected facility that 

qualifies under the provisions of § 60.42c(c) or (d) 

[where percent reduction is not required] does not 

have to measure the parameters Ew or Xk if the owner 

or operator of the affected facility elects to 

measure emission rates of the coal or oil using the

(f) Affected facilities subject to the percent reduction 

requirements under § 60.42c(a) or (b) shall determine 

compliance with the SO2 emission limits under § 60.42c 

pursuant to paragraphs (d) or (e) of this section, and 

shall determine compliance with the percent reduction 

requirements using the following procedures: 

(1) If only coal is combusted, the percent of potential 

SO2 emission rate is computed using the following 

formula: 

%Ps = 100(1 − %Rg/100)(1 − %Rf/100) 

Where 

%Ps Is the percent of potential SO2 emission rate, 

in percent 

%Rg Is the SO2 removal efficiency of the control 

device as determined by Method 19, in percent 

%Rf Is the SO2 removal efficiency of fuel 

pretreatment as determined by Method 19, in 

percent 

(2) If coal, oil, or coal and oil are combusted with 

other fuels, the same procedures required in 

paragraph (f)(1) of this section are used, except as 

provided for in the following: 

(i) To compute the %Ps, an adjusted %Rg (%Rg

) is 

computed from Eaoo

 from paragraph (e)(1) of 

this section and an adjusted average SO2 inlet 

rate (Eaio

) using the following formula:

(ii) To compute Eaio

, an adjusted hourly SO2 inlet 

rate (Ehio

) is used. The Ehio is computed using 

the following formula: 

Ehio

 = [Ehi − Ew (1 − Xk)]/Xk

Where: 

Ehio

 Is the adjusted Ehi, ng/J (lb/million Btu) 

Ehi Is the hourly SO2 inlet rate, ng/J 

(lb/million Btu) 

Ew Is the SO2 concentration in fuels other 

than coal and oil combusted in the 

affected facility, as determined by fuel 

sampling and analysis procedures in 

Method 19, ng/J (lb/million Btu). The 

value Ew for each fuel lot is used for 

each hourly average during the time that 

the lot is being combusted. The owner or 

operator does not have to measure Ew if 

the owner or operator elects to assume Ew

= O. 

Xk Is the fraction of the total heat input 

from fuel combustion derived from coal 

and oil, as determined by applicable 

procedures in Method 19. 

(g) For oil-fired affected facilities where the owner or 

operator seeks to demonstrate compliance with the fuel oil 

sulfur limits under § 60.42c based on shipment fuel 

sampling, the initial performance test shall consist of 

sampling and analyzing the oil in the initial tank of oil 

to be fired in the steam generating unit to demonstrate 

that the oil contains 0.5 weight percent sulfur or less. 

Thereafter, the owner or operator of the affected facility 

shall sample the oil in the fuel tank after each new 

shipment of oil is received, as described under 

§ 60.46c(d)(2). 

(h) For affected facilities subject to § 60.42c(h)(1), (2), or 

(3) where the owner or operator seeks to demonstrate 

compliance with the SO2 standards based on fuel supplier 

certification, the performance test shall consist of the

(1) All CEMS shall be operated in accordance with the 

applicable procedures under Performance 

Specifications 1, 2, and 3 (appendix B). 

(2) Quarterly accuracy determinations and daily 

calibration drift tests shall be performed in 

accordance with Procedure 1 (appendix F). 

(3) For affected facilities subject to the percent 

reduction requirements under § 60.42c, the span value 

of the SO2 CEMS at the inlet to the SO2 control device 

shall be 125 percent of the maximum estimated hourly 

potential SO2 emission rate of the fuel combusted, and 

the span value of the SO2 CEMS at the outlet from the 

SO2 control device shall be 50 percent of the maximum 

estimated hourly potential SO2 emission rate of the 

fuel combusted. 

(4) For affected facilities that are not subject to the 

percent reduction requirements of § 60.42c, the span 

value of the SO2 CEMS at the outlet from the SO2

control device (or outlet of the steam generating 

unit if no SO2 control device is used) shall be 125 

percent of the maximum estimated hourly potential SO2

emission rate of the fuel combusted. 

(d) As an alternative to operating a CEMS at the inlet to the 

SO2 control device (or outlet of the steam generating unit 

if no SO2 control device is used) as required under 

paragraph (a) of this section, an owner or operator may 

elect to determine the average SO2 emission rate by 

sampling the fuel prior to combustion. As an alternative 

to operating a CEMS at the outlet from the SO2 control 

device (or outlet of the steam generating unit if no SO2

control device is used) as required under paragraph (a) of 

this section, an owner or operator may elect to determine 

the average SO2 emission rate by using Method 6B. Fuel 

sampling shall be conducted pursuant to either paragraph 

(d)(1) or (d)(2) of this section. Method 6B shall be 

conducted pursuant to paragraph (d)(3) of this section. 

(1) For affected facilities combusting coal or oil, coal 

or oil samples shall be collected daily in an asfired condition at the inlet to the steam generating 

unit and analyzed for sulfur content and heat content 

according the Method 19. Method 19 provides 

procedures for converting these measurements into the 

format to be used in calculating the average SO2 input 

rate.

(2) As an alternative fuel sampling procedure for 

affected facilities combusting oil, oil samples may 

be collected from the fuel tank for each steam 

generating unit immediately after the fuel tank is 

filled and before any oil is combusted. The owner or 

operator of the affected facility shall analyze the 

oil sample to determine the sulfur content of the 

oil. If a partially empty fuel tank is refilled, a 

new sample and analysis of the fuel in the tank would 

be required upon filling. Results of the fuel 

analysis taken after each new shipment of oil is 

received shall be used as the daily value when 

calculating the 30-day rolling average until the next 

shipment is received. If the fuel analysis shows 

that the sulfur content in the fuel tank is greater 

than 0.5 weight percent sulfur, the owner or operator 

shall ensure that the sulfur content of subsequent 

oil shipments is low enough to cause the 30-day 

rolling average sulfur content to be 0.5 weight 

percent sulfur or less. 

(3) Method 6B may be used in lieu of CEMS to measure SO2

at the inlet or outlet of the SO2 control system. An 

initial stratification test is required to verify the 

adequacy of the Method 6B sampling location. The 

stratification test shall consist of three paired 

runs of a suitable SO2 and carbon dioxide measurement 

train operated at the candidate location and a second 

similar train operated according to the procedures in 

§ 3.2 and the applicable procedures in section 7 of 

Performance Specification 2 (appendix B). Method 6B, 

Method 6A, or a combination of Methods 6 and 3 or 

Methods 6C and 3A are suitable measurement 

techniques. If Method 6B is used for the second 

train, sampling time and timer operation may be 

adjusted for the stratification test as long as an 

adequate sample volume is collected; however, both 

sampling trains are to be operated similarly. For 

the location to be adequate for Method 6B 24-hour 

tests, the mean of the absolute difference between 

the three paired runs must be less than 10 percent 

(0.10). 

(e) The monitoring requirements of paragraphs (a) and (d) of 

this section shall not apply to affected facilities 

subject to § 60.42c(h) (1), (2), or (3) where the owner or 

operator of the affected facility seeks to demonstrate 

compliance with the SO2 standards based on fuel supplier 

certification, as described under § 60.48c(f) (1), (2), or

Administrator. If the petition is approved by the 

Administrator, a facility-specific nitrogen oxides 

emission limit will be established at the nitrogen oxides 

emission level achievable when the affected facility is 

combusting oil or natural gas and byproduct/waste in a 

manner that the Administrator determines to be consistent 

with minimizing nitrogen oxides emissions. 

40 CFR 60.44b(g) 

(g) Any owner or operator of an affected facility that 

combusts hazardous waste (as defined by 40 CFR part 261 or 

40 CFR part 761) with natural gas or oil may petition the 

Administrator within 180 days of the initial startup of 

the affected facility for a waiver from compliance with 

the nitrogen oxides emission limit which applies 

specifically to that affected facility. The petition must 

include sufficient and appropriate data, as determined by 

the Administrator, on nitrogen oxides emissions from the 

affected facility, waste destruction efficiencies, waste 

composition (including nitrogen content), the quantity of 

specific wastes to be combusted and combustion conditions 

to allow the Administrator to determine if the affected 

facility is able to comply with the nitrogen oxides 

emission limits required by this section. The owner or 

operator of the affected facility shall demonstrate that 

when hazardous waste is combusted in the affected 

facility, thermal destruction efficiency requirements for 

hazardous waste specified in an applicable federally 

enforceable requirement preclude compliance with the 

nitrogen oxides emission limits of this section. The 

nitrogen oxides emission limits for natural gas or 

distillate oil in paragraph (a)(1) of this section or for 

residual oil in paragraph (a)(2) of this section, as 

appropriate, are applicable to the affected facility until 

and unless the petition is approved by the Administrator.

NOTE: The intent of these standards is to minimize the emissions 

of VOC through the application of best demonstrated 

technology (BDT). The numerical emission limits in these 

standards are expressed in terms of total organic 

compounds (TOC), measured as TOC less methane and ethane. 

This emission limit reflects the performance of BDT. 

40 CFR 60.661 Definitions. 

As used in this subpart, all terms not defined here shall have 

the meaning given them in the Act and in subpart A of part 60, 
CAAPP PERMIT 

Archer Daniels Midland Company – Decatur Complex 

I.D. Number: 115015AAE 

Application No.: 96030038

and the following terms shall have the specific meanings given 

them. 

Batch distillation operation means a noncontinuous distillation 

operation in which a discrete quantity or batch of liquid feed is 

charged into a distillation unit and distilled at one time. 

After the initial charging of the liquid feed, no additional 

liquid is added during the distillation operation. 

Boiler means any enclosed combustion device that extracts useful 

energy in the form of steam. 

By compound means by individual stream components, not carbon 

equivalents. 

Continuous recorder means a data recording device recording an 

instantaneous data value at least once every 15 minutes. 

Distillation operation means an operation separating one or more 

feed stream(s) into two or more exit stream(s), each exit stream 

having component concentrations different from those in the feed 

stream(s). The separation is achieved by the redistribution of 

the components between the liquid and vapor-phase as they 

approach equilibrium within the distillation unit. 

Distillation unit means a device or vessel in which distillation 

operations occur, including all associated internals (such as 

trays or packing) and accessories (such as reboiler, condenser, 

vacuum pump, steam jet, etc.), plus any associated recovery 

system. 

Flame zone means the portion of the combustion chamber in a 

boiler occupied by the flame envelope. 

Flow indicator means a device which indicates whether gas flow is 

present in a vent stream. 

Halogenated vent stream means any vent stream determined to have 

a total concentration (by volume) of compounds containing 

halogens of 20 ppmv (by compound) or greater. 

Incinerator means any enclosed combustion device that is used for 

destroying organic compounds and does not extract energy in the 

form of steam or process heat. 

Process heater means a device that transfers heat liberated by 

burning fuel to fluids contained in tubes, including all fluids 

except water that is heated to produce steam.

10-196 

Process unit means equipment assembled and connected by pipes or 

ducts to produce, as intermediates or final products, one or more 

of the chemicals in §60.667. A process unit can operate 

independently if supplied with sufficient fuel or raw materials 

and sufficient product storage facilities. 

Product means any compound or chemical listed in §60.667 that is 

produced for sale as a final product as that chemical, or for use 

in the production of other chemicals or compounds. By-products, 

co-products, and intermediates are considered to be products. 

Recovery device means an individual unit of equipment, such as an 

absorber, carbon adsorber, or condenser, capable of and used for 

the purpose of recovering chemicals for use, reuse, or sale. 

Recovery system means an individual recovery device or series of 

such devices applied to the same vent stream. 

Total organic compounds (TOC) means those compounds measured 

according to the procedures in §60.664(b)(4). For the purposes 

of measuring molar composition as required in §60.664(d)(2)(i); 

hourly emissions rate as required in §60.664(d)(5) and 

§60.664(e); and TOC concentration as required in §60.665(b)(4) 

and §60.665(g)(4), those compounds which the Administrator has 

determined do not contribute appreciably to the formation of 

ozone are to be excluded. The compounds to be excluded are 

identified in Environmental Protection Agency's statements on 

ozone abatement policy for State Implementation Plans (SIP) 

revisions (42 FR 35314; 44 FR 32042; 45 FR 32424; 45 FR 48942). 

TRE index value means a measure of the supplemental total 

resource requirement per unit reduction of TOC associated with an 

individual distillation vent stream, based on vent stream flow 

rate, emission rate of TOC net heating value, and corrosion 

properties (whether or not the vent stream is halogenated), as 

quantified by the equation given under §60.664(e). 

Vent stream means any gas stream discharged directly from a 

distillation facility to the atmosphere or indirectly to the 

atmosphere after diversion through other process equipment. The 

vent stream excludes relief valve discharges and equipment leaks 

including, but not limited to, pumps, compressors, and valves. 

40 CFR 60.662 Standards. 

Each owner or operator of any affected facility shall comply with 

paragraph (a), (b), or (c) of this section for each vent stream 

on and after the date on which the initial performance test 

required by §60.8 and §60.664 is completed, but not later than 60 

days after achieving the maximum production rate at which the

start-up, whichever date comes first. Each owner or operator 

shall either: 

40 CFR 60.662(a) 

(a) Reduce emissions of TOC (less methane and ethane) by 98 

weight-percent, or to a TOC (less methane and ethane) 

concentration of 20 ppmv, on a dry basis corrected to 3 

percent oxygen, whichever is less stringent. If a boiler 

or process heater is used to comply with this paragraph, 

then the vent stream shall be introduced into the flame 

zone of the boiler or process heater; or 

40 CFR 60.662(b) 

(b) Combust the emissions in a flare that meets the 

requirements of §60.18; or 

40 CFR 60.662(c) 

(c) Maintain a TRE index value greater than 1.0 without use of 

VOC emission control devices.

increases the operating vent stream flow rate above the 

low flow exemption level in §60.660(c)(6), including a 

measurement of the new vent stream flow rate, as recorded 

under §60.665(i). These must be reported as soon as 

possible after the change and no later than 180 days after 

the change. These reports may be submitted either in 

conjunction with semiannual reports or as a single 

separate report. A performance test must be completed 

with the same time period to verify the recalculated flow 

value and to obtain the vent stream characteristics of 

heating value and ETOC. The performance test is subject 

to the requirements of §60.8 of the General Provisions. 

Unless the facility qualifies for an exemption under the 

low capacity exemption status in §60.660(c)(5), the 

facility must begin compliance with the requirements set 

forth in §60.662.

VOC through the application of best demonstrated 

technology (BDT). The numerical emission limits in these 

standards are expressed in terms of TOC, measured as TOC 

less methane and ethane. This emission limit reflects the 

performance of BDT.) 

40 CFR 60.701 Definitions 

As used in this subpart, all terms not defined here shall have 

the meaning given them in the Act and in subpart A of part 60, 

and the following terms shall have the specific meanings given 

them. 

Batch operation means any noncontinuous reactor process that is 

not characterized by steady-state conditions and in which 

reactants are not added and products are not removed 

simultaneously. 

Boiler means any enclosed combustion device that extracts useful 

energy in the form of steam and is not an incinerator. 

By compound means by individual stream components, not carbon 

equivalents. 

Car-seal means a seal that is placed on a device that is used to 

change the position of a valve (e.g., from opened to closed) in 

such a way that the position of the valve cannot be changed 

without breaking the seal. 

Combustion device means an individual unit of equipment, such as 

an incinerator, flare, boiler, or process heater, used for 

combustion of a vent stream discharged from the process vent. 

Continuous recorder means a data recording device recording an 

instantaneous data value at least once every 15 minutes.

Flame zone means the portion of the combustion chamber in a 

boiler occupied by the flame envelope. 

Flow indicator means a device which indicates whether gas flow is 

present in a line. 

Halogenated vent stream means any vent stream determined to have 

a total concentration (by volume) of compounds containing 

halogens of 20 ppmv (by compound) or greater. 

Incinerator means an enclosed combustion device that is used for 

destroying organic compounds. If there is energy recovery, the 

energy recovery section and the combustion chambers are not of 

integral design. That is, the energy recovery section and the 

combustion section are not physically formed into one 

manufactured or assembled unit but are joined by ducts or 

connections carrying flue gas. 

Primary fuel means the fuel fired through a burner or a number of 

similar burners. The primary fuel provides the principal heat 

input to the device, and the amount of fuel is sufficient to 

sustain operation without the addition of other fuels. 

Process heater means a device that transfers heat liberated by 

burning fuel directly to process streams or to heat transfer 

liquids other than water. 

Process unit means equipment assembled and connected by pipes or 

ducts to produce, as intermediates or final products, one or more 

of the chemicals in §60.707. A process unit can operate 

independently if supplied with sufficient feed or raw materials 

and sufficient product storage facilities. 

Product means any compound or chemical listed in §60.707 which is 

produced for sale as a final product as that chemical, or for use 

in the production of other chemicals or compounds. By-products, 

co-products, and intermediates are considered to be products. 

Reactor processes are unit operations in which one or more 

chemicals, or reactants other than air, are combined or 

decomposed in such a way that their molecular structures are 

altered and one or more new organic compounds are formed. 

Recovery device means an individual unit of equipment, such as an 

absorber, carbon adsorber, or condenser, capable of and used for 

the purpose of recovering chemicals for use, reuse, or sale. 

Recovery system means an individual recovery device or series of 

such devices applied to the same vent stream.

Relief valve means a valve used only to release an unplanned, 

nonroutine discharge. A relief valve discharge results from an 

operator error, a malfunction such as a power failure or 

equipment failure, or other unexpected cause that requires 

immediate venting of gas from process equipment in order to avoid 

safety hazards or equipment damage. 

Secondary fuel means a fuel fired through a burner other than a 

primary fuel burner. The secondary fuel may provide 

supplementary heat in addition to the heat provided by the 

primary fuel. 

Total organic compounds or TOC means those compounds measured 

according to the procedures in §60.704(b)(4). For the purposes 

of measuring molar composition as required in §60.704(d)(2)(i) 

and §60.704(d)(2)(ii), hourly emission rate as required in 

§60.704(d)(5) and §60.704(e), and TOC concentration as required 

in § 60.705(b)(4) and §60.705(f)(4), those compounds which the 

Administrator has determined do not contribute appreciably to the 

formation of ozone are to be excluded. 

Total resource effectiveness or TRE index value means a measure 

of the supplemental total resource requirement per unit reduction 

of TOC associated with a vent stream from an affected reactor 

process facility, based on vent stream flow rate, emission rate 

of TOC, net heating value, and corrosion properties (whether or 

not the vent stream contains halogenated compounds), as 

quantified by the equation given under § 60.704(e). 

Vent stream means any gas stream discharged directly from a 

reactor process to the atmosphere or indirectly to the atmosphere 

after diversion through other process equipment. The vent stream 

excludes relief valve discharges and equipment leaks. 

40 CFR 60.702 Standards. 

Each owner or operator of any affected facility shall comply with

(1) Visually inspect the internal floating roof, the 

primary seal, and the secondary seal (if one is in 

service), prior to filling the storage vessel with 

VOL. If there are holes, tears, or other openings in 

the primary seal, the secondary seal, or the seal 

fabric or defects in the internal floating roof, or 

both, the owner or operator shall repair the items 

before filling the storage vessel. 

(2) For Vessels equipped with a liquid-mounted or 

mechanical shoe primary seal, visually inspect the 

internal floating roof and the primary seal or the 

secondary seal (if one is in service) through 

manholes and roof hatches on the fixed roof at least 

once every 12 months after initial fill. If the 

internal floating roof is not resting on the surface 

of the VOL inside the storage vessel, or there is 

liquid accumulated on the roof, or the seal is 

detached, or there are holes or tears in the seal 

fabric, the owner or operator shall repair the items 

or empty and remove the storage vessel from service 

within 45 days. If a failure that is detected during 

inspections required in this paragraph cannot be 

repaired within 45 days and if the vessel cannot be 

emptied within 45 days, a 30-day extension may be 

requested from the Administrator in the inspection 

report required in §60.115b(a)(3). Such a request 

for an extension must document that alternate storage 

capacity is unavailable and specify a schedule of 

actions the company will take that will assure that 

the control equipment will be repaired or the vessel 

will be emptied as soon as possible. 

(3) For vessels equipped with a double-seal system as 

specified in §60.112b(a)(1)(ii)(B): 

(i) Visually inspect the vessel as specified in 

paragraph (a)(4) of this section at least

in the seal or the seal fabric, or the secondary seal 

has holes, tears, or other openings in the seal or 

the seal fabric, or the gaskets no longer close off 

the liquid surfaces from the atmosphere, or the 

slotted membrane has more than 10 percent open area, 

the owner or operator shall repair the items as 

necessary so that none of the conditions specified in 

this paragraph exist before refilling the storage 

vessel with VOL. In no event shall inspections 

conducted in accordance with this provision occur at 

intervals greater than 10 years in the case of 

vessels conducting the annual visual inspection as 

specified in paragraphs (a)(2) and (a)(3)(ii) of this 

section and at intervals no greater than 5 years in 

the case of vessels specified in paragraph (a)(3)(i) 

of this section. 

(5) Notify the Administrator in writing at least 30 days 

prior to the filling or refilling of each storage 

vessel for which an inspection is required by 

paragraphs (a)(1) and (a)(4) of this section to 

afford the Administrator the opportunity to have an 

observer present. If the inspection required by 

paragraph (a)(4) of this section is not planned and 

the owner or operator could not have known about the 

inspection 30 days in advance or refilling the tank, 

the owner or operator shall notify the Administrator 

at least 7 days prior to the refilling of the storage 

vessel. Notification shall be made by telephone 

immediately followed by written documentation 

demonstrating why the inspection was unplanned.

(2) Determine gap widths and areas in the primary and 

secondary seals individually by the following 

procedures: 

(i) Measure seal gaps, if any, at one or more 

floating roof levels when the roof is floating 

off the roof leg supports. 

(ii) Measure seal gaps around the entire 

circumference of the tank in each place where 

a 0.32-cm diameter uniform probe passes freely 

(without forcing or binding against seal) 

between the seal and the wall of the storage 

vessel and measure the circumferential 

distance of each such location. 

(iii) The total surface area of each gap described 

in paragraph (b)(2)(ii) of this section shall 

be determined by using probes of various 

widths to measure accurately the actual 

distance from the tank wall to the seal and 

multiplying each such width by its respective 

circumferential distance. 

(3) Add the gap surface area of each gap location for the 

primary seal and the secondary seal individually and 

divide the sum for each seal by the nominal diameter 

of the tank and compare each ratio to the respective 

standards in paragraph (b)(4) of this section.

Section 212.126 Adjusted Opacity Standards Procedures 

a) Pursuant to Section 28.1 of the Environmental Protection 

Act (Act) [415 ILCS 5/28.1], and in accordance with 35 

Ill. Adm. Code 106, Subpart E, provisions for adjusted 

standards for visible emissions for emission units subject 

to Sections 212.201, 212.202, 212.203, or 212.204 of this 

Part shall be granted by the Board to the extent 

consistent with federal law based upon a demonstration by 

such owner or operator that the results of a performance 

test conducted pursuant to this Section, Section 212.110 

of this Part, and Methods 5 and 9 of 40 CFR part 60, 

Appendix A, incorporated by reference in Section 212.113 

of this Part, show that the emission unit meets the 

applicable particulate emission limitations at the same 

time that the visible emissions exceed the otherwise 

applicable standards of Sections 212.121 through 212.125 

of this Subpart. Such adjusted opacity limitations: 

1) Shall be specified as a condition in operating 

permits issued pursuant to 35 Ill. Adm. Code 201 and 

Section 39.5 of the Act; 

2) Shall substitute for that limitation otherwise 

applicable; 

3) Shall not allow an opacity greater than 60 percent at 

any time; and 

4) Shall allow opacity for one six-minute averaging 

period in any 60 minute period to exceed the adjusted 

opacity standard. 

b) For the purpose of establishing an adjusted opacity 

standard, any owner or operator of an emission unit which 

meets the requirements of subsection (a) of this Section, 

may request the Agency to determine the average opacity of 

the emissions from the emission unit during any 

performance tests conducted pursuant to Section 212.110 of 

this Part and Methods 5 and 9 of 40 CFR part 60, Appendix 
A, incorporated by reference in Section 212.113 of this 

Part. The Agency shall refuse to accept the results of 

emissions tests if not conducted pursuant to this Section. 

c) Any request for the determination of the average opacity 

of emissions shall be made in writing, shall include the 

time and place of the performance test and test 

specifications and procedures, and shall be submitted to 

the Agency at least thirty (30) days before the proposed 

test date. 

d) The Agency will advise the owner or operator of an 

emission unit which has requested an opacity determination 

of any deficiencies in the proposed test specifications 

and procedures as expeditiously as practicable but no 

later than ten (10) days prior to the proposed test date 

so as to minimize any disruption of the proposed testing 

schedule. 

e) The owner or operator shall allow Agency personnel to be 

present during the performance test. 

f) The method for determining an adjusted opacity standard is 

as follows: 

1) A minimum of 60 consecutive minutes of opacity 

readings obtained in accordance with Test Method 9, 

40 CFR part 60, Appendix A, incorporated by reference 

in Section 212.113 of this Part, shall be taken 

during each sampling run. Therefore, for each 

performance test (which normally consists of three 

sampling runs), a total of three sets of opacity 

readings totaling three hours or more shall be 

obtained. Concurrently, the particulate emissions 

data from three sampling runs obtained in accordance 

with Test Method 5, 40 CFR part 60, Appendix A, 

incorporated by reference in Section 212.113 of this 

Part, shall also be obtained. 

2) After the results of the performance tests are 

received from the emission unit, the status of 

compliance with the applicable particulate emissions 

limitation shall be determined by the Agency. In 

accordance with Test Method 5, 40 CFR part 60, 

Appendix A, incorporated by reference in Section 

212.113 of this Part, the average of the results of 

the three sampling runs must be less than the 

allowable particulate emission rate in order for the 

emission unit to be considered in compliance. If 

compliance is demonstrated, then only those test runs 

with results which are less than the allowable 

particulate emission rate shall be considered as 
acceptable test runs for the purpose of establishing 

an adjusted opacity standard. 

3) The opacity readings for each acceptable sampling run 

shall be divided into sets of 24 consecutive 

readings. The six (6) minute average opacity for 

each set shall be determined by dividing the sum of 

the 24 readings within each set by 24. 

4) The second highest six (6) minute average opacity 

obtained in subsection (f)(3) of this Section shall 

be selected as the adjusted opacity standard. 

g) The owner or operator shall submit a written report of the 

results of the performance test to the Agency at least 

thirty (30) days prior to filing a petition for an 

adjusted standard with the Board. 

h) If, upon review of such owner’s or operator’s written 

report of the results of the performance tests, the Agency 

determines that the emission unit is in compliance with 

all applicable emission limitations for which the 

performance tests were conducted, but fails to comply with 

the requirements of Section 212.122 or 212.123 of this 

Subpart, the Agency shall notify the owner or operator as 

expeditiously as practicable, but no later than twenty 

(20) days after receiving the written report of any 

deficiencies in the results of the performance tests. 

i) The owner or operator may petition the Board for an 

adjusted visible emission standard pursuant to 35 Ill. 

Adm. Code 106.Subpart E. In addition to the requirements 

of 35 Ill. Adm. Code 106.Subpart E, the petition shall 

include the following information: 

1) A description of the business or activity of the 

petitioner, including its location and relevant 

pollution control equipment; 

2) The quantity and type of materials discharged from 

the emission unit or control equipment for which the 

adjusted standard is requested; 

3) A copy of any correspondence between the petitioner 

and the Agency regarding the performance tests which 

form the basis of the adjusted standard request; 

4) A copy of the written report submitted to the Agency 

pursuant to subsection (g) of this Section; 

5) A statement that the performance tests were conducted 

in accordance with this Section and the conditions 
and procedures accepted by the Agency pursuant to 

Section 212.110 of this Part; 

6) A statement regarding the specific limitation 

requested; and 

7) A statement as to whether the Agency has sent notice 

of deficiencies in the results of the performance 

test pursuant to subsection (h) of this Section and a 

copy of said notice. 

j) In order to qualify for an adjusted standard the owner or 

operator must justify as follows: 

1) That the performance tests were conducted in 

accordance with Test Methods 5 and 9, 40 CFR part 60, 

Appendix A, incorporated by reference in Section 

212.113 of this Part, and the conditions and 

procedures accepted by the Agency pursuant to Section 

212.110 of this Part; 

2) That the emission unit and associated air pollution 

control equipment were operated and maintained in a 

manner so as to minimize the opacity of the emissions 

during the performance tests; and 

3) That the proposed adjusted opacity standard was 

determined in accordance with subsection (f) of this 

Section. 

k) Nothing in this Section shall prevent any person from 

initiating or participating in a rulemaking, variance, or 

permit appeal proceeding before the Board.

PART 212 

VISIBLE AND PARTICULATE MATTER EMISSIONS 

SUBPART S: AGRICULTURE 

Section 212.461 Grain Handling and Drying in General 

a) Sections 212.302(a), 212.321, and 212.322 of this Part 

shall not apply to grain-handling and grain-drying 

operations, portable grain-handling equipment and one-turn 

storage space. 

b) Housekeeping Practices. All grain-handling and graindrying operations, regardless of size, must implement and 

use the following housekeeping practices: 
1) Air pollution control devices shall be checked daily 

and cleaned as necessary to insure proper operation. 

2) Cleaning and Maintenance. 

A) Floors shall be kept swept and cleaned from 

boot pit to cupola floor. Roof or bin decks 

and other exposed flat surfaces shall be kept 

clean of grain and dust that would tend to rot 

or become airborne. 

B) Cleaning shall be handled in such a manner as 

not to permit dust to escape to the 

atmosphere. 

C) The yard and surrounding open area, including 

but not limited to ditches and curbs, shall be 

cleaned to prevent the accumulation of rotting 

grain. 

3) Dump Pit. 

A) Aspiration equipment shall be maintained and 

operated. 

B) Dust control devices shall be maintained and 

operated. 

4) Head House. The head house shall be maintained in 

such a fashion that visible quantities of dust or 

dirt are not allowed to escape to the atmosphere. 

5) Property. The yard and driveway of any source shall 

be asphalted, oiled or equivalently treated to 

control dust. 

6) Housekeeping Check List. Housekeeping check lists to 

be developed by the Agency shall be completed by the 

manager and maintained on the premises for inspection 

by Agency personnel. 

c) Exemptions. Any grain-handling operation for which 

construction or modification commenced prior to June 30, 

1975, having a grain through-put of not more than 2 

million bushels per year and located inside a major 

population area and any grain-handling operation or graindrying operation for which construction or modification 

commenced prior to June 30, 1975, located outside of a 

major population area which is required to apply for a 

permit pursuant to Sections 212.462 and 212.463 of this 

Subpart, respectively, shall receive such permit 

notwithstanding the control requirements of those 

respective rules provided said operation can demonstrate 
that the following conditions exist upon application for, 

or renewal of, an operating permit: 

1) The requirements of subsection (b) of this Section 

are being met; and 

2) No certified investigation is on file with the Agency 

indicating that there is an alleged violation prior 

to issuance of the permit. 

A) If a certified investigation is on file with 

the Agency indicating an alleged violation, 

any applicant may obtain an exemption for 

certain operations if said applicant can prove 

to the Agency that those parts of his 

operation for which he seeks exemption are not 

the probable cause of the alleged violation. 

B) Applicants requesting an exemption in 

accordance with the provisions of subsection 

(c)(2)(A) of this Section may be granted an 

operating permit for a limited time, not to 

exceed twelve (12) months in duration, if an 

objection is on file with the Agency on which 

a certified investigation has not been made 

prior to issuance of the permit. 

C) An applicant may consider denial of an 

exemption under this rule as a refusal by the 

Agency to issue a permit. This shall entitle 

the applicant to appeal the Agency’s decision 

to the Board pursuant to Section 40 of the Act 

[415 ILCS 5/40]. 

d) Loss of Exemption. Any grain-handling operation or graindrying operation for which construction or modification 

commenced prior to June 30, 1975, that has received an 

operating permit pursuant to the provisions of subsection 

(c) of this Section shall apply for an operating and/or 

construction permit pursuant to 35 Ill. Adm. Code 201 

within sixty (60) days after receipt of written notice 

from the Agency that a certified investigation is on file 

with the Agency indicating that there is an alleged 

violation against the operation. The construction permit 

application shall include a compliance plan and project 

completion schedule showing the grain-handling operation’s 

program or grain-drying operation’s program for complying 

with the standards and limitations of Section 212.462 or 

212.463 of this Subpart as the case may be, within a 

reasonable time after the date on which notice of a 

certified investigation indicating alleged pollution was 

received by said operation; provided, however, any such 

operation shall not be required to reduce emissions from 
those parts of the operation that the applicant can prove 

to the Agency are not the probable cause of the pollution 

alleged in the certified investigation. 

1) The written notice of loss of exemption is not a 

final action of the Agency appeal able to the Board. 

2) Denial of a permit requested pursuant to this 

subsection is a final action appeal able to the Board 

under Section 40 of the Act [415 ILCS 5/40]. 

e) Circumvention. It shall be a violation of this regulation 

for any person or persons to attempt to circumvent the 

requirements of this regulation by establishing a pattern 

of ownership or source development which, except for such 

pattern of ownership or source development, would 

otherwise require application of Section 212.462 or 

212.463 of this Subpart. 

f) Standard on Appeal to Board. In ruling on any appeal of a 

permit denial under subsection (c) or (d) of this Section, 

the Board shall not order the permit to be issued by the 

Agency unless the applicant who has appealed the permit 

denial has proved to the Board that the grain-handling 

operation or grain-drying operation which is the subject 

of the denied application is not injurious to human, plant 

or animal life, to health, or to property, and does not 

unreasonably interfere with the enjoyment of life or 

property. 

g) Alternate Control of Particulate Emissions. 

1) Grain-handling or grain-drying operations, which were 

in numerical compliance with Section 212.322 of this 

Part, as of April 14, 1972, and continue to be in 

compliance with Section 212.322 of this Part need not 

comply with the provisions under this Subpart, except 

the housekeeping practices in this subsection and 

subsection (b) of this Section. 

2) Grain-handling or grain-drying operations, which were 

not in numerical compliance with Section 212.322 of 

this Part, as of April 14, 1972, but which came into 

compliance with Section 212.321 of this Part prior to 

April 14, 1972, and continue to be in compliance with 

Section 212.321 of this Part need not comply with the 

provisions under this Subpart, except the 

housekeeping practices in this subsection and in 

subsection (b) of this Section. 

3) Proof of compliance with said rule shall be made by 

stack sampling and/or material balance results 

obtained from actual testing of the subject emission 
unit or process and be submitted at the time of an 

application for, or renewal of, an operating permit. 

h) Severability. If any provision of these rules and 

regulations is adjudged invalid, such invalidity shall not 

affect the validity of this 35 Ill. Adm. Code, Subtitle B, 

Chapter I as a whole or of any Part, Subpart, sentence or 

clause thereof not adjudged invalid.

Section 212.462 Grain Handling Operations 

Unless otherwise exempted pursuant to Section 212.461(c) or (d) 

of this Subpart, or allowed to use alternate control according to 

Section 212.461(g) of this Subpart, existing grain-handling 

operations with a total annual grain through-put of 300,000 

bushels or more shall apply for an operating permit pursuant to 

35 Ill. Adm. Code 201, and shall demonstrate compliance with the 

following: 

a) Cleaning and Separating Operations. 

1) Particulate matter generated during cleaning and 

separating operations shall be captured to the extent 

necessary to prevent visible particulate matter 

emissions directly into the atmosphere. 

2) For grain-handling sources having a grain through-put 

of not more than 2 million bushels per year or 

located outside a major population area, air 

contaminants collected from cleaning and separating 

operations shall be conveyed through air pollution 

control equipment which has a rated and actual 

particulate removal efficiency of not less than 90 

percent by weight prior to release into the 

atmosphere. 

3) For grain-handling sources having a grain through-put 

exceeding 2 million bushels per year and located 

within a major population area, air contaminants 

collected from cleaning and separating operations 

shall be conveyed through air pollution control 

equipment which has a rated and actual particulate 

removal efficiency of not less than 98 percent by 

weight prior to release into the atmosphere. 

b) Major Dump-Pit Area. 

1) Induced Draft. 

A) Induced draft shall be applied to major dump 

pits and their associated equipment 
(including, but not limited to, boots, hoppers 

and legs) to such an extent that a minimum 

face velocity is maintained, at the effective 

grate surface, sufficient to contain 

particulate emissions generated in unloading 

operations. The minimum face velocity at the 

effective grate surface shall be at least 200 

fpm, which shall be determined by using the 

equation: 

V = Q/A 

Where: 

V = Face velocity; and 

Q = Induced draft volume in scfm; and 

A = Effective grate area in ft2

; and 

B) The induced draft air stream for grainhandling sources having a grain through-put of 

not more than 2 million bushels per year or 

located outside a major population area shall 

be confined and conveyed through air pollution 

control equipment which has an overall rated 

and actual particulate collection efficiency 

of not less than 90 percent by weight; and 

C) The induced draft air stream for grainhandling sources having a grain through-put 

exceeding 2 million bushels per year and 

located in a major population area shall be 

confined and conveyed through air pollution 

control equipment which has an overall rated 

and actual particulate collection efficiency 

of not less than 98 percent by weight; and 

D) Means or devices (including, but not limited 

to, quick-closing doors, air curtains or wind 

deflectors) shall be employed to prevent a 

wind velocity in excess of 50 percent of the 

induced draft face velocity at the pit; 

provided, however, that such means or devices 

do not have to achieve the same degree of 

prevention when the ambient air wind exceeds 

25 mph. The wind velocity shall be measured, 

with the induced draft system not operating, 

at a point midway between the dump-pit area 

walls at the point where the wind exits the 

dump-pit area, and at a height above the dumppit area floor of approximately 2 ft; or 
2) Any equivalent method, technique, system or 

combination thereof adequate to achieve, at a 

minimum, a particulate matter emission reduction 

equal to the reduction which could be achieved by 

compliance with subsection (b)(1) of this Section. 

(Board Note: Pursuant to Section 9 of the Act, 

certain country grain elevators are exempt from 

subsection (b) of this Section.) 

c) Internal Transferring Area. 

1) Internal transferring area shall be enclosed to the 

extent necessary to prohibit visible particulate 

matter emissions directly into the atmosphere. 

2) Air contaminants collected from internal transfer 

operations for grain-handling sources having a grain 

through-put of not more than 2 million bushels per 

year or located outside a major population area shall 

be conveyed through air pollution control equipment 

which has a rated and actual particulate removal 

efficiency of not less than 90 percent by weight 

prior to release into the atmosphere. 

3) Air contaminants collected from internal transfer 

operations for grain-handling sources having a grain 

through-put exceeding 2 million bushels per year and 

located in a major population area shall be conveyed 

through air pollution control equipment which has a 

rated and actual particulate removal efficiency of 

not less than 98 percent by weight prior to release 

into the atmosphere. 

d) Load-Out Area. 

1) Truck and hopper car loading shall employ socks, 

sleeves or equivalent devices which extend 6 inches 

below the sides of the receiving vehicle, except for 

topping off. Choke loading shall be considered an 

equivalent method as long as the discharge is no more 

than 12 inches above the sides of the receiving 

vehicle. 

2) Box car loading shall employ means or devices to 

prevent the emission of particulate matter into the 

atmosphere to the fullest extent which is 

technologically and economically feasible. 

3) Watercraft Loading. 

A) Particulate matter emissions generated during 

loading for grain-handling sources having a 
grain through-put of not more than 2 million 

bushels per year or located outside a major 

population area shall be captured in an 

induced draft air stream, which shall be 

ducted through air pollution control equipment 

that has a rated and actual particulate matter 

removal efficiency of not less than 90 percent 

by weight prior to release into the 

atmosphere. 

B) Particulate matter emissions generated during 

loading for grain-handling sources having a 

grain through-put exceeding 2 million bushels 

per year and located in a major population 

area shall be captured in an induced draft air 

stream, which shall be ducted through air 

pollution control equipment that has a rated 

and actual particulate removal efficiency of 

not less than 98 percent by weight prior to 

release into the atmosphere; except for the 

portion of grain loaded by trimming machines 

for which particulate matter emission 

reductions, at a minimum, shall equal the 

reduction achieved by compliance with 

subsection (d)(3)(A) of this Section. 

e) New and Modified Grain-Handling Operations. Grainhandling operations for which construction or modification 

commenced on or after June 30, 1975, shall file 

applications for construction and operating permits 

pursuant to 35 Ill. Adm. Code 201, and shall comply with 

the control equipment requirements of this Section, except 

for grain-handling operations for which construction or 

modification commenced on or after June 30, 1975, which 

will handle an annual grain through-put of less than 

300,000 bushels; provided, however, that for the purpose 

of this Subpart, an increase in the annual grain throughput, without physical alterations or additions to the 

grain-handling operation, shall not be considered a 

modification unless such increase exceeds 30 percent of 

the annual grain through-put on which the operation’s 

original construction and/or operating permit was granted. 

If the grain-handling operation has been operating 

lawfully without a permit, its annual grain through-put 

shall be determined as set forth in the definition of the 

term "annual grain through-put."

750 bushels per hour for 5 percent moisture extraction at 

manufacturer’s rated capacity (using the American Society of 

Agricultural Engineers Standard 248.2, Section 9, Basis for 

Stating Drying Capacity of Batch and Continuous-Flow Grain 

Dryers, incorporated by reference in Section 212.113 of this 

Part) shall be operated in such a fashion as to preclude the 

emission of particulate matter larger than 300 microns mean 

particle diameter, shall apply for an operating permit pursuant 

to 35 Ill. Adm. Code 201, and shall comply with the following: 

a) Column Dryers. The largest effective circular diameter of 

transverse perforations in the external sheeting of a 

column dryer shall not exceed 0.094 inch, and the grain 

inlet and outlet shall be enclosed. 

b) Rack Dryers. No portion of the exhaust air of rack dryers 

shall be emitted to the ambient atmosphere without having 

passed through a particulate collection screen having a 

maximum opening of 50 mesh, U.S. Sieve Series. 

1) All such screens will have adequate self-cleaning 

mechanisms, the exhaust gas of which for grainhandling facilities having a grain through-put of not 

more than 2 million bushels per year or located 

outside a major population area shall be ducted 

through air pollution control equipment which has a 

rated and actual particulate removal efficiency of 90 

percent by weight prior to release into the 

atmosphere. 

2) All such screens will have adequate self-cleaning 

mechanisms, the exhaust gas of which for grainhandling sources having a grain through-put exceeding 

2 million bushels per year and located in a major

Section 212.464 Sources in Certain Areas 

a) Applicability. Notwithstanding Section 212.461 of this 

Subpart, this Section shall apply to those sources located 

in the Lake Calumet area as defined in Section 

212.324(a)(1)(B) of this Part. 

b) Emission Limitations 

1) No person shall cause or allow the emission of PM-10, 

other than that of fugitive particulate matter, into 

the atmosphere to exceed 22.9 mg/scm (0.01 gr/scf) 

during any one hour period from any process emission 

unit engaged in the drying, storing, mixing or 

treating of grain except for column grain dryers; in 

addition, no person shall cause or allow visible 

emissions of PM-10 other than fugitive particulate 

matter from grain conveying, transferring, loading, 

or unloading operations including garners, scales and

A determination of non-compliance based on any subsection of this 

Section shall not be refuted by evidence of compliance with any 

other subsection. 

a) Sulfur Dioxide Measurement. Measurement of sulfur dioxide 

emissions from stationary sources shall be made according 

to an applicable method specified in 40 CFR 60, Appendix 

A, Method 6, 6A, 6B, or 6C, incorporated by reference in 

Section 214.104(a), or by measurement procedures 

established pursuant to 40 CFR 60.8(b), incorporated by 

reference in Section 214.104(b). (Ill. Rev. Stat. 1989, 

Ch. 111 1/2, par. 1010.) 

b) Sulfuric Acid Mist and Sulfur Trioxide Measurement. 

Measurement of sulfuric acid mist and sulfur trioxide 

shall be according to the barium-thorin titration method 

specified in 40 CFR 60, Appendix A, Method 8, incorporated 

by reference in Section 214.104(a). 
c) Solid Fuel Averaging Measurement Daily Analysis Method. 

This subsection applies to sources at plants with total 

solid fuel-fired heat input capacity exceeding 439.5 MW 

(1500 million Btu/hr). If daily fuel analysis is used to 

demonstrate compliance or non-compliance with Sections 

214.122, 214.141, 214.142(a) 214.162, 214.186 and 214.421,

SUBPART B: NEW FUEL COMBUSTION EMISSION SOURCES 
Section 217.121 New Emission Sources 

No person shall cause or allow the emission of nitrogen oxides 

(NOx) into the atmosphere in any one hour period from any new fuel 

combustion emission source with an actual heat input equal to or 

greater than 73.2 MW (250 MBtu/hr) to exceed the following 

standards and limitations: 

a) For gaseous fossil fuel firing, 0.310 kg/MW-hr (0.20 

lbs/MBtu) of actual heat input; 

b) For liquid fossil fuel firing, 0.464 kg/MW-hr (0.30 

lbs/MBtu) of actual heat input; 

c) For dual gaseous and liquid fossil fuel firing, 0.464 

kg/MW-hr (0.30 lbs/MBtu) of actual heat input; 

d) For solid fossil fuel firing, 1.08 kg/MW-hr (0.7 

lbs./MBtu) of actual heat input; 

e) For fuel combustion emission sources burning 

simultaneously any combination of solid, liquid and 

gaseous fossil fuels, an allowable emission rate shall be 

determined by the following equation: 

E = (AG + BL + CS) Q 

Where: 

E = Allowable nitrogen oxides emissions rate 

Q = Actual heat input derived from all fossil fuels 

G = Percent of actual heat input derived from gaseous 

fossil fuel 

L = Percent of actual heat input derived from liquid 

fossil fuel 

S = Percent of actual heat input derived from solid 

fossil fuel 

G + L + S = 100.0 

and, where A, B, C and appropriate metric and English 

units are determined from the following table:
