following: 

(i) The system shall provide for zero (low-level value between 0 to 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 shall, as a minimum, be adjusted whenever the 

24-hour zero drift or 24-hour span drift exceeds two times the limits of the applicable 

performance specifications in Appendix B. The systemmust allow the amount ofexcess zero 

and span drift measured at the 24-hour interval checks to be recorded and quantified, 

whenever specified. 

(ii) Except for systembreakdown, repairs, calibration checks, and zero and span adjustments, the 

monitoring systems shall be in continuous operation and shall complete a minimum of one 

cycle of operation (sampling, analyzing, and data recording) for each successive 15-minute 

period. 

(iii) The monitoring systems shall incorporate measurements capable of calculating the SO, and 

NO, emission rates in units of the allowable emission rates (lbh). In lieu of a flow rate 

device, the permittee may submit for the Division's approval an alternative method for

Permit 3 1-098 Page 42 
"BACT" or 'fBest available control techno1ogy"means an emission limitation (including a visible emission standard) 

based on the maxirmundegree ofreduction of each pollutant subject to regulationunder the WAQSRor regulationunder 

theFederal Clean Air Act, whichwouldbe emitted bmor which results for anyproposedmajor emitting facility or major 

modification whichthe Administrator, on a case-by-case basis, taking into account energy, environmental, and economic 

impacts and other costs, determines is achievable for such source or modification through application or production 

processes and available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel 

combustion techniques for control of such pollutant. If the Administrator determines that technological or economic 

limitations on the application ofmeasurement methodology to a particular class ofsources would make the imposition of 

an emission standard infeasible, he may instead prescribe a design, equipment, work practice or operational standard or 

combination thereof to satisfy the requirement ofBest Available Control Technology. Such standard shall, to the degree 

possible, set forth the emission reduction achievable by implementation of such design, equipment, work practice, or 

operation and shall provide for compliance by means which achieve equivalent results. Application of BACT shall not 

result in emissions in excess of those allowed under Chapter 5, Section 2 of the WAQSR and any other new source 

performance standard or national emission standards for hazardous air pollutants promulgated by EPA but not yet adopted 

by the state. 

"Department" means the Wyoming Department of Environmental Quality or its Director. 

"Director" means the Director of the Wyoming Department of Environmental Quality. 

"Division "means the Air Quality Division of the Wyoming Department of Environmental Quality or its Administrator. 

"Emergency" means any situation arising fiom sudden and reasonably unforeseeable events beyond the control of the 

source, including acts of God, which situation requires immediate corrective action to restore normal operation, and that 

causes the source to exceed a technology-based emission limitation under the permit, due to unavoidable increases in 

emissions attributable to the emergency. .An emergency shall not include noncompliance to the extent caused by 

improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error. 

"EPA " means the Administrator of the U.S. Environmental Protection Agency or the Administrator's designee. 

"Fuel-burning equipment" means any furnace, boiler apparatus, stack, or appurtenances thereto used in the process of 

burning fuel or other combustible material for the purpose of producing heat or power by indirect heat transfer. 

"Fugitive emissions" means those emissions which could not reasonably pass through a stack chimney, vent, or other 

functionally equivalent opening. 

'Tnsigni~cantactivities "means thoseactivities whichare incidental to the facility's primarybusiness activity and which 

result inemissions ofless than one tonper year ofaregulatedpollutantnot included in the Section 1 12 (b) list ofhazardous 

air pollutants or emissions less than 1000 pounds per year of a pollutant regulated pursuant to listing under Section 1 12 

(b) of the Act provided, however, such emission levels of hazardous air pollutants do not exceed exemptions based on 

insignificant emission levels established by EPA through rulemaking for modification under Section 1 12 (g) of the Act. 

"MACT" or "Maximum achievable control technology" means the maximum degree ofreduction in emissions that is 

deemed achievable for new sources in a category or subcategory that shall not be less stringent than the emission control 

that is achieved in practice by the best controlled similar source, as determined by the Administrator. Emission standards 

promulgated for existing sources in a category or subcategory may be less stringent than standards for new sources in the 

same category or subcategory but shall not be less stringent, and may be more stringent than: 

(a) the average emission limitation achieved by the best performing 12 percent ofthe existing sources (for 

whichthe Admirustrator has emissioninformation), excludingthosesources that have, within 1 8 months 

before the emission standard is proposed or within 30 months before such standard is promulgated, 

whichever is later, first achleved a level of emission rate or emission reduction which complies, or 

Permit 3 1-098 Page 43 
would comply if the source is not subject to such standard, with the lowest achievable emission rate 

applicable to the source category and prevailing at the time, in the category or subcategory for 

categories and subcategories with 30 or more sources, or 

(b) the average emission limitation achieved by the best performing five sources (for which the 

. Administrator has or could reasonably obtainemissions information) inthe category or subcategory for 

categories or subcategories with fewer than 30 sources. 

"Modification " means any physical change in, or change in the method of operation of, an affected facility which 

increases the amount of any air pollutant (to which any state standards applies) emitted by such facility or which results 

in the emission of any such air pollutant not previously emitted. 

"Permittee" rneans the person or entity to whom a Chapter 6, Section 3 permit is issued. 

"Potentialto emitWmeans the maximum capacity of a stationary source to emit any air pollutant under its physical and 

operational design. Any physical or operational limitation on the capacity ofa source to emit an air pollutant, including 

air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, 

storedorprocr:ssed, shall betreatedaspart ofits design ifthe limitation is enforceable by EPA and the Division. This term

All terms used in this subpart that are not 

defined in this section have the meaning 

given to them in the CAA and in subpart A of 

this part. 

Alkali bypass means a duct between the feed 

end of the kiln and the preheater tower 

through which a portion of the kiln exit gas 

stream is withdrawn and quickly cooled by 

air or water to avoid excessive buildup of 

alkali, chloride andlor sulfur on the raw feed. 

This may also be referred to as the "kiln 

exhaust gas bypass". 

Bagging system means the equipment which 

fills bags with portland cement. 

Bin means a manmade enclosure for storage 

of raw materials, clinker, or finished product 

prior to further processing at a portland 

cement plant.

clinker product leaving the kiln is placed to 

be cooled by air supplied by a forced draft or 

natural draft supply system. 

Continuous monitor means a device which 

continuously samples the regulated parameter 

specified in 6 63.1 350 of this subpart without 

interruption, evaluates the detector response 

at least once every 15 seconds, and computes 

and records the average value at least every 

60 seconds, except during allowable periods 

of calibration and except as defined otherwise 

by the continuous emission monitoring 

system performance specifications in 

appendix B to part 60 of this chapter. 

Conveying system means a device for 

transporting materials from one piece of 

equipment or location to another location 

within a facility. Conveying systems include 

but are not limited to the following: feeders, 

belt conveyors, bucket elevators and 

pneumatic systems. 

Conveying system transfer point means a 

point where any material including but not 

limited to feed material, fuel, clinker or 

product, is transferred to or from a conveying 

system, or between separate parts of a 

conveying system.

penta-, hexa-, hepta-, and octachlorinated 

materials, whichinclude but are not limited 

to materials such as limestone, clay, shale, 

sand, iron ore, mill scale, cement kiln dust 

and flyash, that are fed to the kiln. Feed dots 

not include the fuels used in the kiln to 

pmduce heat to form the clinker product. 

Finish mill means a roll crusher, ball and tube 

mill or other size reduction equipment used to 

grind clinker to a fine powder. dypsum and 

other materials may be added to and blended 

with clinker in a finish mill. The finish mill 

also includes the air separator associated with 

the finish mill.

chapter. 

In-line kiln/raw mill means a system in a 

portland cement production process where a 

dry kiln system is integrated with the raw mill 

so that all or a portion of the kiln exhaust 

gases are used to perform the drying 

operation of the raw mill, with no auxiliary 

heat source used. In this system the kiln is 

capable of operating without the raw mill 

operating, but the raw mill cannot operate 

without the kiln gases, and consequently, the 

raw mill does not generate a separate exhaust 

gas stream.

used to gnnd feecl to the appropriate size. 

Moisture may be added or removed from the 

feed during the grinding operation. If the raw 

mill is used to remove moisture from feed 

materials, it is also, by definition, a raw 

material dryer. The raw mill also includes the 

air separator associated with the raw mill. 

Rolling average means the average of all 

one-minute averages over the averaging 

period. 

Run average means the average of the 

one-minute parameter values for a run.

remain in compliance, the opacity must be 

maintained such that the 6-minute average 

opacity for any 6-minute block period does 

not exceed 10 percent. If the average opacity 

for any 6-minute block period exceeds 10 

percent, this shall constitute a violation of the 

standard. If the owner or operator chooses to 

install a BLDS in lieu of conducting the daily 

visual emissions testing required under 

paragraph (e) of this section, the requirements 

in paragraphs (m)(l) through (9) of this 

section apply to each BLDS: 

(1) The BLDS must be certified by the 

manufacturer to be capable of detecting PM 

emissions at concentrations of 10 milligrams 

per actual cubic meter (0.0044 grains per 

actual cubic foot) or less. 'Certify" shall 

mean that the instrument manufacturer has 

tested the instrument on gas streams having a 

range of particle size distributions and 

confirmed by means of valid filterable PM 

~etection Guidance" (EPA-4541~-98-615, 

September 1997). 

(7) The baseline output of the system must be 

established as follows: 

(i) Adjust the range and the averaging period 

of the device; and 

(ii) Establish the alarm set points and the 

alarm delay time. 

(8) After initial adjustment, the range, 

averaging period, alarm set points, or alarm 

delay time may not be adjusted except as 

specified in the operations and maintenance 

plan required by paragraph (a) of this section. 

In no event may the range be increased by 

more than I00 percent or decreased by more 

than 50 percent over a I calendar year period 

unless a responsible official as defined in tj 

63.2 certifies in writing to the Administrator 

that the fabric filter has been inspected and 

found to be in good operating condition. 

(9) The owner or operator must maintain and 

operate the fabric filter such that the bag leak 

detector alarm is not activated and alarm 

condition does not exist for more than 5 

percent of the total operating time in a 6- 

month block period. Each time the alarm 

activates, alarm time will be counted as the 

actual amount of time taken by the owner or 

operator to initiate corrective actions. If 

inspection of the fabric filter demonstrates 

that no corrective actions are necessary, no 

alarm time will be counted. The owner or 

operator must continuously record the output

C. Monitoring Approach 

1. Lndicator 

Visible emissions will be used as an indicator. 

2. Measurement 

EPA Reference Method 22-like procedures will be employed at the exhaust of the pollution 

control device for the above sources. 

3. Frequency of Measurements 

Observations, using oneminute "see" or "no-see" results, will be performed daily 
4. Indicator Range 

No detectable emision opacity 

5. Quality Improvement Plan (OP) lhreshold 

. The QIP threshold is six excursions within a six mmth reporting period. 

6. Performance Criteria 

Measurements are to be made at the emission point. 

7. Verification of Operational Status 

Records will indicate if equipment was operational during the monitoring period. Daily 

production and throughput rates are kept on file. 

8. QA / QC Practices and Criteria 

Observers will be Method 22 trained and will adhere to Method 22-like procedures. 

D. Justification 

1. Background 

'Ihis facility manufactures Portland cement. Raw material, which provides the necessary 

composition of silica, calcium, iron, alumina, etc., is ground to a he texture and is heated in 

one of two kilns. The heated material, referred to as clinker, is ground to a finer size along 

with other additives such as gypsum, resulting in Portland cement. The product is loaded into 

trucks or rail cars or is sent elsewhere for bagging. Dust collection control is employed 

throughout the process. Except kiln #5 dust collection is performed with fabric filters (i.e., 

dust collectors and baghouses). An electrostatic precipitator (ESP) provides dust control for 

kiln #2. 

2. Rationale for Selection of Performance Indicator 

Visible emissions observations are deemed a good performance indicator since the findings 

are quickly obtained and are indicative of the dust collectors' efficiency. Visible emissions 

will not be observed exiting a properly operating particulate matter control device. 

Conversely, such emissions will become visible if a dust collector is not kctiming 

satisfactorily. 

3. Rationale for Selection of Indicator Level 

The selected indicator range is no visible emissions. Using an EPA Reference Method 22- 

like protocol, a "see" or "no-see" method for evaluating dust collectors' efficiency was 

selected at this facility because: (1) it is an approved method, (2) it is quickly performed, (3) 

it can be used to evaluate the many dust collectors functioning throughout the facility, (4) it 

does not require a Method 9 certified observer, (5) it can be used while the process is 

operating, and (6) it has the advantage of detecting a problem at a distance instead of relying 

on close examination of gauges or similar metering devices. The scheduled daily inspection 

of each point source will be over a one-minute period. This time interval will be sufficient to 

provide reasonable assurance that the pollution control device is operating satisfactorily. 

Secondary observations and reporting of visible emissions by workers throughout the 

remainder of the day will provide additional assurance of compliance. 
Findings of the above observations will be recorded and kept an file. -Wh an excursion is 

detected, bitittian of caredive actions will be initiated within one how with the preparation 

of a work or& that notifies mainhumce personnel of the problem. Once the cause of the 

exmian is ddammed, pasoxme1 and equipment will be assigned to cosrect the prob1an.- 

. The selected Quality Improvement Plan (QIP) threshold for visible emissions firm the above 

dust collectors is six exaxrsim within a 6-mmth reporting period. 'Ibis threshold level 

represents approximately 3 percent of the total visible emissions observations. If the 

threshold is exceeded m a semianuual reporting period, a QIP will be developed and 

implemented.

C. Monitoring Approach 

1. Measurement 

Opacity will be measured with continuous opacity monitors (COW). 

2. Frequency of Measurements 

Opacity at the exhaust stacks of the above equipment is continuously monitored with 

continuous opacity monitors (COW). Six-minute averages of the readings are recorded and 

kept on file. 

3. Indicator Range 

The permitted opacity limit for the different equipment will be used as an indicator. The 

federally enforced limits are 10% for clinker coolers and 20% for kilns. 

4. Performance Criteria 

Measurements will be taken inside exhaust stacks for the above equipment within EPA 

required monitor location specifications. 

5. Verification of Operational Status 

Records will be kept on file of equipment operating hours and production/throu@put rates. 

Also, records of excursions will be maintained along with explanations of the cause of the 

excursion and corrective action(s) taken. 

6. OA 1 QC Practices and Criteria 

Daily calibrations are performed on the continuous opacity monitors and records of the 

calibration results are kept on file. 

D. Justification 

1. Background 

Kilns are integral in the cement manufacturing process. During the pyroprocess, raw material 

is heated to extreme temperatures and converted into clinker. The heating process involves 

many chemical reactions that are controlled by closely monitoring and adjusting the 

chemistry of the raw material and parameters of the heating process. 

Clinker formed in the kilns is then transferred to clinker coolers where it is rapidly cooled. 

The cooling "locks in" the chemical structures and allows the product to be handled. 

Subsequently, the clinker is ground with additives in finish mills. The fmal product of the 

grinding process is Portland cement. 

At Mountain Cement Company, there are two kilns; both of which are equipped with a 

clinker cooler. The exhaust gases 6om the kilns traverse air pollution control devices 

designed to remove dust fiom the gases. The control device for Kiln #I is a multicompartment baghouse which contains 2,268 fabric filter bags. Kiln #2 uses an electrostatic 

precipitator for removing dust 6om its exhaust gases. Dust removed from the gases from 

both kilns is either returned to the process or wasted. The cleaned gases are emitted into the 

atmosphere through exhaust stacks. Both kilns are equipped with their own stack. 

Continuous emissions monitors situated on each stack analyze the gases for certain pollutants 

and the opacity of the emissions. The latter serves as a surrogate measurement for the amount 

of particulate matter contained in the gases.

as records of raw material content and usage, 

or records documenting compliance with 

work practice requirements). The conduct of 

-compliance method tests, such as the 

procedures in 40 CFRpart 60, Appendix A, 

on a routine periodic basis nlay be 

considered monitoring (or as a supplement to 

other monitoring), provided that 

requirements to conduct such tests on a onetime basis or at such times as a regulatory 

authority may require on a non-regular basis

an assumed control device emission 

reduction factor that wuld be affected by the 

actual operation and maintenance of the 

control device (such as a surface coating line 

controlled by an incinerator for which 

continuous compliance is determined by 

calculating emissions on the basis of coating 

records and an assumed control device 

efficiency factor based on an initial

(i) General criteria. To prpvide a reasonable 

assurance of compliance with emission 

limitations or standards for the anticipated 

range of operations at a pollutant-specific 

emissions unit, monitoring unda this part 

shall meet the following general criteria: 

(A) The owner or operator shall design the 

monitoring to obtain data for one or more 

indicators of emission control performance 

for the control device, any associated capture 

system and, if necessary to satisfy paragraph 

(cXiXB) of this section, processes at a 

pollutant-specific emissions unit. Indicators 

of performance may include, but are not 

limited to, direct or predicted emissions 

(including visible emissions or opacity), 

process and control device parameters that 

affect control device (and capture system) 

efficiency or emission rates, or recorded 

findings of inspection and maintenance 

activities conducted by the owner or 

operator. (B) The owner or operator shall 

establish an appropriate rang+) or 

designated condition(s) for the selected 

indicato4s) such that operation within the 

ranges provides a reasonable assurance of 

ongoing compliance with emission 

limitations or standards for the anticipated 

range of operating conditions. Such range(s) 

or condition(s) shall reflect the proper 

operation and maintenance of the control 

device (and associated capture system), in 

accordance with applicable design 

properties, for minimizing emissions over the 

anticipated range of operating conditions at 

least to the level required to achieve 

compliance with the applicable requirements. 

The reasonable assurance of compliance will 

be assessed by maintaining performance 

within the indicator range(s) or designated 

condition(s). The ranges shall be established 

in accordance with the design and 

performance requirements in this section and 

documented in accordance with the 

requirements in Chapter 7, Section 3(d). If 

Chapter 7, Section 3 - Page 3 
necessary to assure that the control device 

and associated capture system can satisfy 

this criterion, the owner or operator shall 

monitor appropriate process operational 

parameters (such as total throughput where 

necessary to stay within the rated capacity 

for a control device). In addition, unless 

specifically stated otherwise by an applicable 

requirement, the owner or operator shall 

monitor indicators to detect any bypass of 

the control device (or capture system) to the 

atmosphere, if such bypass can occur based 

quality assurance and control practices; 

0) Specifications for the 'equency of 

conducting the monitoring, the data 

collection procedures that will be used (e.g., 

computerized data acquisition and handling,

value if appropriate (e.g., maintaining 

condenser temperatures a certain number of 

degrees below-the condensation temperature 

of the applicable compound(s) being 

processed) or at multiple levels that are 

relevant to distinctly different operating 

conditions (e.g., high versus low load levels); 

(11) Expressed as a function of process 

variables (e.g., an indicator range expressed 

as minimum to maximum pressure drop 

across a venturi throat in a particulate control 

scrubber); 

(111) Expressed as maintaining the 

applicable parameter in a particular 

operational status or designated condition 

(e.g.. position of a damper controlling gas 

flow to the atmosphere through a by-pass 

duct); 

(IV) Established as interdependent between 

more than one indicator. 

(ii) Performanc~: criteria. The owneror 

operator shall design the monitoring to meet 

the following performance criteria: 

(A) Specificatic~ns that provide for obtaining 

data that are representative of the emissions 

or parameters being monitored (such as 

detector location and installation 

specifications, if applicable); 

(B) For new or modified monitoring 

equipment, verification procedures to 

confirm the operational status of the 

monitoring prior to the date by which the 

owner or operator must conduct monitoring 

under this part as specified in Chapter 7, 

Section 3(g)(i). The owner or operator shall 

consider the monitoring equipment 

manufacturer's requirements or 

recommendations for installation, 

calibration, and start-up operation; 

(C) Quality assurance and control practices 

that are adequate to ensure the continuing 

validity of the data. The owner or operator 

shall consider rnanufacturer 

recommendatio~ns or requirements applicable 

to the monitoring in developing appropriate 

associated capture system). Such intervals 

shall.be commensurate with the time period 

over which a change in control device 

performance that would require actions by 

owner or operator to return operations within 

normal ranges or designated conditions is 

likely to be observed. 

(11) For all pollutant-specific emissions units 

with the potential to emit, calculated 

including the effect of control devices, the 

applicable regulated air pollutant in an 

amount equal to or greater than 100 percent 

of the amount, in tons per year, required for a 

source to be classified as a major source, for 

each parameter monitored, the owner or 

operator shall collect four or more data 

values equally spaced over each hour and 

average the values, as appl~cable, over the 

applicable averaging period as determined in 

accordance with paragraph (c)(ii)(D)(I) of 

-this section. The Division may approve a 

reduced data collection frequency, if 

appropriate, based on information presented 

by the owner or operator concerning the data 

collection mechanism available for a 

particular parameter for the particular 

pollutant-specific emissions unit (e.g., 

integrated raw material or fuel analysis data, 

noninstrumental measurement of waste feed 

rate or visible emissions, use of a portable 

analyzer or an alarm sensor). 

(111) For other pollutant-specific emissions 

units, the frequency of data collection may 

be less than the frequency specified in 

subparagraph (c)(ii)(D)(lI) of this section but 

the monitoring shall include some data 

collection at least once per 24-hour period 

(e.g., a daily inspection of a carbon adsorber 

operation in conjunction with a weekly or 

monthly check of emissions with a portable 

analyzer). 

(iii) Evaluation factors. In designing 

monitoring to meet the requirements in 

paragraphs (c)(i) and (c)(ii) of this section, 

the owner or operator shall take into account 

site-specific factors including the 

applicability of existing monitoring 

(B) The use of a CEMS, COMS, or PEMS 

that satisfies any of the following monitoring 

requirements shall be deemed to satisfy the 

general design criteria in paragraphs (c)(i) 

and (c)(ii) of this section, provided that a 

COMS may be subject to the criteria for 

establishing indicator ranges under paragraph 

(c)(i) of this section:

for the proposed elemmts of the monitoring. 

If the performance specifications prowsed to 

satisfy Chapter 7, section 3(c)(ii$)or (C) 

include differences from manufacturer 

recommendations, the owner or operator 

shall explain the reasons for the differences 

between the requirements proposed by the 

owner or operator and the manufacturer's 

recommendations or requirements. The 

owner or operator also shall submit any data 

supporting the justification, and may refer to 

generally available sources of information 

used to support the justification (such as 

generally available air pollution engineering 

manuals, or EPA publications on appropriate 

monitoring for various types of control 

devices or capture systems). To justify the 

appropriateness of the monitoring elements 

proposed, the owner or operator may rely in 

part on existing applicable requirements that 

establish the monitoring for the applicable 

pollutant-specific emissions unit or a similar 

unit. If an owner or operator relies on 

presumptively acceptable monitoring, no 

further justification for the appropriateness 

of that monitoring should be necessary other 

than an explanation of the applicability of 

such monitoring to the unit in question, 

unless data or information is brought forward 

to rebut the assumption. Presumptively 

acceptable monitoring includes: 

(A) Presumptively acceptable or required 

monitoring approaches, established by the 

Division in a rule that constitutes part of the

Section 3(d)(iv), the owner or opetator shall 

submit control device (and process and 

capture system, if applicable) operating 

oarameter data obtained durinn - the conduct 

of the applicable compliance or performance 

test conducted under conditions specified by 

the applicable rule. If the applicable rule - does not specify testing conditions or only 

partially specifies test conditions, the - 

performance test generally shall be 

conducted under conditions representative of 

maximum emissions potential under 

anticipated operating conditions at the 

pollutant-specific emissions unit. Such data 

may be supplemented, ifdesired, by 

engineering assessments and manufacturer's 

recommendations to justify the indicator 

ranges (or, if applicable, the procedures for 

establishing such indicator ranges). 

Emission testing is not required to be 

conducted over the entire indicator range or 

range of potential emissions. 

(B) The owner or operator must document 

that no changes to the pollutant-specific 

emissions unit, including the control device 

and capture system, have taken place that 

could result in a significant change in the 

control system performance or the selected 

ranges or designated conditions for the 

indicators to be monitored since the 

performance or compliance tests were 

conducted. 

(iv) If existing data from unit-specific 

compliance or performance testing specified 

in Chapter 7, Section 3(d)(iii) are not 

available, the owner or operator: 

(v) If the monitoring submitted by the owner

other necessary activities prior to use of the 

monitoring for purposes of this pa* the 

owner or operator shall include an 

implementation plan and schedule for 

installing, testing and performing any other 

appropriate activities prior to use of the 

monitoring. The implementation plan and 

schedule shall provide for use of the 

monitoring as expeditiously as practicable 

after approval of the monitoring in the 

Chapter 6, Section 3 operating permit 

pursuant to Chapter 7, Section 3(0, but in no 

case shall the schedule for completing 

installation and beginning operation of the 

monitoring exceed 180 days after approval of 

the permit. 

(vi) If a control device is comn to more 

than one pollutant-specific emissions unit, 

the owner or operator may submit monitoring 

for the control device and identify the 

pollutant-specific emissions units affected 

and any process or associated capture device 

conditions that must be maintained or 

monitored in accordance with Chapter 7, 

Section 3(c)(i) rather than submit separate 

monitoring for each pollutant-specific 

emissions unit. 

(vii) If a single pollutant-specific emissions 

unit is controlled by more than one control 

device similar in design and operation, the 

owner or operator may submit monitoring 

that applies to all the control devices and 

identify the control devices affected and any

sufficient to satisfy the requirements of this 

part and to confirm the appropriateness of an 

indicator range(s) or designated condition(s) 

proposed to satisfy Chapter 7, Section 

3(cXiXB) and (C) and consistent with the 

schedule in Chapter 7, Section 3(dXv). 

(iii) If the Division approves the proposed 

monitoring, the Division shall establish one 

or more pennit terms or conditions that 

speciTy the required monitoring in 

accordance with Chapter 6, Section 

3(h)(iXcXI). At a minimum, the permit shall 

specify: 

(A) The approved monitoring approach that 

includes all of the following: 

(I) The indicator(s) to be monitored (such as 

temperature, pressure drop, emissions, or 

similar parameter); 

(11) The means or device to be used to 

measure the indicator(s) (such as temperature 

measurement device, visual observation, or 

CEMS); and 

(111) The performance requirements 

established to satisfy Chapter 7, Section

-operator will define an exceedance or 

excursion for purposes of responding to and 

reporting exceedances or excursions under 

chapter7, Section 303) and (h). The permit 

shall specify the level at which an excursion 

or exceedance will be deemed to occur, 

including the appropriate averaging period 

associated with such exceedance or 

excursion. For defining an excursion from 

an indicator range or designated condition, 

the permit may either include the spccific 

value(s) or condition(s) at which an 

excursion shall occur, or the specific 

procedures that will be used to establish that 

value or condition. If the latter, the pcrmit 

shall specify appropriatc notice procedures 

for the owner or operator to notify thc 

Division upon any establishmcnt or 

reestablishment of the value. 

(C) The obligation to conduct the 

monitoring and fulfill the other obligations 

specified in Chapter 7, Section 3(g) through 

(1). 

(D) If appropriate, a minimum data 

availability requirement for valid data 

collection for each averaging period, and, if 

appropriate, a minimum data availability 

requirement for the averaging periods in a 

reporting period. 

(iv) If the monitoring proposed by the owner 

or operator requires installation, testing or 

final verification of operational status. the 

Chapter 6. Section 3 operating permit shall 

include an enforceable schedule with 

appropriate milestones for completing such 

installation, testing, or final verification 

consistent with the requirements in Chapter 

7, Section 3(dXv). 

(v) If the Division disapproves the proposed 

monitoring, the following applies: 

(A) The draft or final permit shall include, at 

a minimum, monitoring that satisfies the 

requirements of Chapter 6, Section 

3(hXiXCXI)(2.); 

(B) The Division shall include in the draft or 

final permit a compliance schedule for the 

source owner to submit monitoring that 

satisfies Chapter 7, Section 3(c) and (d), but 

in no case shall the owner or operator submit 

revised monitoring more than 180 days from 

the date of issuance of the Chapter 6, Section 

3 operating permit; and 

(C) If the source owner or operator does not 

submit the monitoring in accordance with the 

compliance schedule as required in Chapter 

7, Section 3(f)(v)(B) or if the Division 

disapproves the monitoring submitted, the 

source owner or operator shall be deemed not 

in compliance with Chapter 7, Section 3, 

unless the source owner or operator 

successfully challenges the disapproval. 

(g) Operation of approved monitoring. 

(i) Commencement ofoperation. The owner 

or operator shall conduct the monitoring 

required under this part upon issuance of a 

Chapter 6, Section 3 operating permit that 

includes such monitoring, or by such later 

date specified in the permit pursuant to 

Chapter 7, Section 3(fXv). 

(ii) Proper maintenance. At all times, the 

owner or operator shall maintain the 

monitoring, including but not limited to, 

maintaining necessary parts for routinc 

repairs of the monitoring equipment.

applicable, monitoring malfunctions, 

associated repairs, and required quality 

assurance or control activities (including, as 

applicable, calibration checks and requircd 

zero and span adjustmcnts), the o\\ner or 

operator shall conduct all monitoring in 

continuous operation (or shall collect data at 

all required intervals) at all times that thc 

pollutant-specific emissions unit is operating. 

Data rccorded during monitoring 

malfunctions, associated repairs, and 

required quality assurance or control 

activities shall not be used for purposes of 

this part, including data averages and 
calculations, or fulfilling a minimum data 

availability rquirnrmt, if applicable. The ' owner or operator shall usc all the data 

collected during all other periods in 

assessing the opelation of the control device 

and associated control system. A monitoring 

malfunction is any sudden, inficquent, not 

reasonably preventable failure of the 

monitoring to provide valid data. Monitoring 

failum that arc caused in part by poor 

maintenance or careless operation arc not 

malfunctions. 

(iv) Response to excursions or exceedances. 

(A) Upon detecting an excursion or 

exceedance, the owner or opcrator shall 

restore operation of the pollutant-specific 

emissions unit (including the control device 

and associated capture system) to its normal 

or usual manner of option as 

expeditiously as practicable in accordance 

with good air pollution control practices for 

minimizing emissions. The response shall 

include minimizing the period of any startup, 

shutdown or malfunction and taking any 

necessary corrective actions to restore 

normal operation and prevent the likely 

recurrence of the cause of an excursion or 

exceedance (other than those caused by 

excused startup or shutdown conditions). 

Such actions may include initial inspection 

and evaluation, recording that operations 

returned to normal without operator action 

(such as through response by a computerized 

distribution control system), or any necessary 

follow-up actions to return operation to 

within the indicator range, designated 

condition, or below the applicable emission 

limitation or standard. as ae~licable.

(i) Based on the results of qdetermination 

made under Chapter 7, Section 3(gXiv)@), 

the Administrator or the Division may 

require the owner or operator to develop and 

implemnt a QIP. Consistent with Chapter 

7. Section 3(fXiiiXC). the Chapter 6. Section 

3 operating pennit may specify an 

appropriate threshold, such as an 

accumulation of cxcaadances or excursions 

excecding 5 percent duration of a pollutantspecific emissions unit's operating time for a 

reporting period, for requiring the 

implementation of a QIP. The threshold may 

be sef at a higher or lower percent or may 

rely on other criteria for purposes of 

indicating whether a pollutant-specific 

emissions unit is being maintained and 

operated in a manner consistent with good 

air pollution control practices. 

(ii) Elements of a QIP. 

(A) The owner or operator shall maintain a 

written QIP, if required, and have it available 

for inspection.

under this part, if the owner or operator 

identifies a failure to achieve compliance 

with an emission limitation or standard for 

which the approved monitoring did not 

provide an indication of an excursion or 

exceedance while providing valid data, or the 

results of compliance or performance testing 

document a need to modify the existing 

indicator ranges or designated conditions, the 

owner or operator shall promptly notify the 

Division and, if necessary, submit a proposed 

modification to the Chapter 6, Section 3

Mr. William k ans sin^; ~nvironmental Manager 

Mountain Cement Company 

5 Sand Creek Road 

Laramie, Wyoming 82070 

Dear Mr. Sansing: 

We are writing in response to your request dated September 8,2003 for an alternative 

testing approach to be used at the Mountain Cement Company facility located in Laramie, 

Wyoming. As we understand it, Mountain Cement is subject to the requirements of 40 CFR 60, 

Subpart LLL, National Emission Standards for Hazardous Air Pollutants hm the Portland 

Cement Manufacturing Industry. As such, Mountain Cement is required to conduct performance 

testing under 463.1349@)(2) using Method 9 (40 CFR Part 60, Appendix A) to determine 

compliance with opacity limits set forth in 463.1348. 

I In your request, you explain that Mountain Cement has a number of emission 'sources that 

are enclosed within buildings and propose in lieu of conducting Method 9 testing of individuals 

affected sources inside the buildings to conduct Method 22 (40 CFR Part 60, Appendix A) 

observations f& visible emissions on the sides and roof of the buildings as well as Method 

opacity observations of the building vents. 

Although Subpart LLL of Part 63 does not specifically address alternative test methods 

for materials handling equipment located inside buildings, we are willing to defer to the approach 

under the Standards for Performance for Nonmetallic Mineral Processing Plants (40 CFR Part 

60, Subpart 000, 460.672 (e)) which is identical to what you have proposed, and which states: 

"the building enclosing the affected facility or facilities must comply with the following emission 

limits: (1) No owner or operator shall cause to discharge into the atmosphere fiom any building 

enclosing any transfer point on a conveyor belt or any other affected facility any visible fugitive 

emissions except emissions fiom a vent as defined in 560.671. (2) No owner or operator shall 

cause to be discharged into the atmosphere from any vent of any building enclosing any transfer 

point on a conveyor belt or any other affected facility any emissions which exceed the stack 

emissions limits ..." 

In specific, to apply this approach, Mountain Cement in Laramie, Wyoming must meet 

the following two requirements: 

(1) For each building enclosing materials handling and conveyingsystem equipment affected 

sources, conduct observations for visible emissions other than condensed water vapor 

Internet Address (URL) http:llwww.epa.gov 

RecycledlRecyclable .Printed with Vegetable Oil Based Inks on Recycled Paper (Minimum 25% Postconsumer) 
ding Method 22. The observatiom most be while dl a&cted matexi& 

processing operations within the building are opmting and muit be at least 75 minutes in 

duration for each building, with each side of the building and roof being observed for at 

least 15 minutes each. The observation position should be at least 15, but not more 1,320 

feet from kach side of the building with the sun or other light source gmerally at the 

observer's back. 

(2) For each emission point (defined as a vent under 960.671) from a building enclosing c 

materials handling and conveying system equipment affected sources, conduct 'opacity 

observations using Method 9. Each vent must be observed for at least 3 hours to obtain at 

least thirty, 6-minute averages. The duration of the Method 9 performance test may be 

reduced to l-hour if (a) there are no individual readings greater than 10 percent opacity 

and (b) there are no more than three readings of 10 percent for the first l-hour period. 

The results of the (1) Method 22 observations of any building must show no visible emissions and 

(2) Method 9 observations of any vents must meet the opacity limits set forth in 963.1348. 

If you have any questions regarding this alternative, please contact Robin Segall of my 

staff at 9 19-54 1-0893 or segall.robin@epa.gov. 

Sincerely, I ' I
