Operational Limits & Requirements

The owner/operator of this equipment shall comply with the operational limits and requirements listed 

below. 

1. Holcim shall implement speed controls designed to ensure that the average speed of the haul trucks 

on the M3 limestone haul road does not exceed 20 miles per hour. The speed controls shall consist 

of speed limit signs and stop signs along the route. 
 Title V Permit 11/10/005 23

2. Unpaved Haul Road Trip Restrictions: 

(i) The maximum number of round trips per day and per calendar year on the M3 limestone 

haul road shall be limited to the values listed below. 

Truck Capacity 

(tons of material) 

Maximum Number of Round Trips 

per Day 

Maximum Number of 

Round Trips per Year 

25 40 8,000 

130 77 27,043 

(ii) The number of round trips per day on the M3 limestone haul road shall be entered in a daily 

log to demonstrate compliance with this requirement. The daily logs shall be retained for a 

period of two years(1) following the date of such entries and shall be made available to the 

DNR upon request. This record keeping shall be an on-going requirement and shall not 

terminate. 

(iii) Traffic on the unpaved portion of the M4 haul road shall be limited to scraper travel only, 

with the exception of dozer and compactor vehicles used to maintain the pile integrity and 

size limitation. The maximum number of round trips per day and per calendar year on the 

M4 haul road shall be limited to 200 and 70,080 trips, respectively. The scraper capacity 

shall be limited to 27 tons of material per trip. These maximum numbers of round trips and 

scraper capacity shall not be increased unless a dispersion modeling analysis, acceptable to 

the DNR, is submitted to demonstrate that compliance with the PM10 NAAQS will be 

maintained. 

3. Control of Fugitive Emissions from Unpaved Haul Roads 

(i) Fugitive emissions from the M3 limestone haul road shall be controlled by applying 

a chemical dust suppressant. A control efficiency of 95 percent shall be maintained 

on the entire length of both segments of the limestone haul road. The M3 limestone haul 

road is approximately 30 feet wide and approximately 2.9 miles long, giving it a total area 

of approximately 51,040 square yards. Thus, approximately 2,552 gallons of the selected 

chemical dust suppressant shall be applied no less frequently than once every other week to 

maintain the established ground inventory. This equates to 0.05 gallons of chemical dust 

suppressant per square yard, or a manufacturer's equivalent application to achieve the 95 

percent control efficiency. Different manufacturer's materials have different applications to 

achieve 95 percent control. Documentation supporting a different concentration will be 

maintained onsite by Holcim and submitted to the DNR, as required. 

(ii) Fugitive emissions from the unpaved portion of the M4 haul road shall be controlled by 

applying a chemical dust suppressant. Applications of the selected chemical dust 

suppressant and the record keeping requirements described below shall begin by January 

23, 2004. A control efficiency of 95 percent shall be maintained on the unpaved portion of 

the M4 haul road. The unpaved portion of the M4 haul road is approximately 30 feet wide 

and approximately 0.19 miles long, giving it a total area of approximately 3,344 square

(1) In addition to the ACO requirement of maintaining records for at least two (2) years, 567 IAC 

22.108(4)"b" requires that records shall be kept for at least five (5) years. 
 Title V Permit 11/10/005 24

yards. Approximately 167 gallons of the selected chemical dust suppressant shall be applied 

no less frequently than once every other week to maintain the ground inventory. This 

equates to 0.05 gallons of chemical dust suppressant per square yard, or a manufacturer's 

equivalent application to achieve the 95 percent control efficiency. Different manufacturer's 

materials have different applications to achieve 95 percent control. Documentation 

supporting a different concentration will be maintained onsite by Holcim and submitted to 

the DNR, as required. 

(iii) If the selected chemical dust suppressant can not be applied because the ambient air 

temperature (as measured at the facility during daylight operating hours) will be less than 

350 F (1.70 C) or conditions due to weather, in combination with the application of the 

chemical dust suppressant, could create hazardous driving conditions, then the chemical 

dust suppressant application shall be postponed and applied as soon after the scheduled 

application date as the conditions preventing the application have abated. Records of the 

applications shall be maintained and shall include the dates of each application, the 

chemical dust suppressant used, the application intensity (gals./sq.yd.), dilution ratio, the 

areas treated, the operator's initials, and documentation of road and weather conditions, if 

necessary. If the selected chemical dust suppressant is not applied as planned, then the 

records should so indicate and provide an explanation. The records shall be retained for a 

period of five years following the date of the above entries and shall be made available to 

the DNR upon request. This record keeping requirement shall be an on-going requirement 

and shall not terminate. 

(iv) In the event Holcim (US) Inc. does not use (or plan to use) haul roads M3 and the unpaved 

portion of M4 for fourteen (14) days or more, Holcim (US) Inc. shall not be required to 

apply the chemical dust suppressant as provided in paragraph 3(i) and 3(ii), respectively. 

Prior to using such haul road again, however, an application (at the bi-weekly rate) shall be 

made subject to the conditions of paragraph 3(iii). 

4. Paved Haul Road Trip Restrictions: 

The maximum number of round trips per day and per calendar year on the M1, M2, M4, and M5 

paved haul roads, for all haul trucks, combined, shall be limited to the values listed below. 

Haul Road Maximum Number of Round Trips 

per Day 

Maximum Number of Round Trips per 

Year 

M1 96 17,520 

M2 312 43,800

M5 192 26,280 

The number of round trips per day on the M1, M2, the paved portion of M4, and the M5 haul roads 

shall be entered into a daily log to demonstrate compliance with the maximum number of round 

trips per day limitation. A daily rolling count of the total number of round trips per day on M1, M2, 

the paved portion of M4, and M5 shall be maintained to demonstrate compliance with the 

maximum number of round trips per year limitation. The daily logs shall be retained for a period of 

two years(1) following the date of such entries and shall be made available to the DNR upon 

request. 

(1) In addition to the ACO requirement of maintaining records for at least two (2) years, 567 IAC 22.108(4)"b" 

requires that records shall be kept for at least five (5) years. 
 Title V Permit 11/10/005 25

 This record keeping shall be an on-going requirement and shall not terminate. 

5. Control of Fugitive Emissions from Paved Haul Roads 

(i) Fugitive emissions from the paved haul roads M1, M2, M4, and M5 shall be controlled to 

an effective control efficiency of 80 percent by water flushing followed by sweeping. The 

control efficiency of 80 percent shall be achieved by water flushing followed by sweeping 

haul roads M1, M2, the paved portion of M4, and M5 once per day. The following table 

contains the approximate size of each haul road in square yards and the approximate 

amount of water to be applied to each road in each application. The water quantities are 

based on a spray rate of approximately 0.23 gallons per square yard.

(ii) If water flushing followed by sweeping can not be accomplished because the ambient air 

temperature (as measured at the facility during daylight operating hours) will be less than 

350 F (1.70 C) or conditions due to weather, in combination with the application of the 

water, could create hazardous driving conditions, then the water flushing and sweeping 

shall be postponed and accomplished as soon after the scheduled date as the conditions 

preventing the application have abated. Additionally, water flushing and sweeping need not 

occur when a rain gauge located at the site indicates that at least 0.2 inches of precipitation 

(water equivalent) has occurred within the preceding 24-hour time period or the road(s) will 

not be used on a given day. 

(iii) Records of the applications shall be maintained and shall include the dates of each 

application, the amount of water applied, the areas treated, and the operator's initials. If 

water is not applied when scheduled due to the conditions specified in 5(ii) above, the 

conditions which prevented such application, or made such application unnecessary, shall 

be documented. The records shall be retained for a period of two years(1) following the date 

of the above entries and shall be made available to the DNR upon request. This record 

keeping shall be an on-going requirement and shall not terminate.

In accordance with NESHAP Subpart LLL, the facility (plant number 17-01-009) shall install, 

calibrate, maintain, and operate a continuous opacity monitoring system (COMS) for measuring the 

opacity of the emissions discharged to the atmosphere and record the output of the system. The system 

shall be designed to meet the 40 CFR 60, Appendix B, Performance Specification 1 (PS1). 

In accordance with NESHAP Subpart LLL [40 CFR §63.1350(f)], the facility (plant number 17-01-

005) shall install, calibrate, maintain, and continuously operate a continuous monitor to record the 

temperature of the exhaust gases from the kiln at the inlet to or upstream of the kiln particulate matter 

control device. Per 40 CFR §63.1350(f), the following shall be done: 

3⁄4 The recorder response range must include zero and 1.5 times either of the average temperatures 

established according to the requirements in 40 CFR §63.1349(b)(3)(iv). 

3⁄4 The reference method must be a National Institute of Standards and Technology calibrated 

reference thermocouple-potentiometer system or alternate reference, subject to approval by the 

Administrator. 

3⁄4 The three-hour average temperature shall be calculated as the average of 180 successive oneminute average temperatures. 

3⁄4 Periods of time when one-minute averages are not available shall be ignored when calculating 

three-hour rolling averages. When one-minute averages become available, the first one-minute 

average is added to the previous 179 values to calculate the three-hour rolling average. 

3⁄4 The calibration of all thermocouples and other temperature sensors shall be verified at least 

once every three months. 

Compliance with the sulfur dioxide emission limit of this permit shall be continuously demonstrated by 

the owner/operator through the use of a continuous emission monitoring system (CEMS). Therefore, 

the facility (plant number 17-01-009) shall install, calibrate, maintain, and operate a CEMS for kiln 3 

for measuring sulfur dioxide emissions discharged to the atmosphere and record the output of the 

system. The system shall be designed to meet the 40 CFR 60, Appendix B, Performance Specification

G13. Hazardous Release 

The permittee must report any situation involving the actual, imminent, or probable release of a 

hazardous substance into the atmosphere which, because of the quantity, strength and toxicity of the 

substance, creates an immediate or potential danger to the public health, safety or to the environment. 

A verbal report shall be made to the department at (515) 281-8694 and to the local police department 

or the office of the sheriff of the affected county as soon as possible but not later than six hours after 

the discovery or onset of the condition. This verbal report must be followed up with a written report as 

indicated in 567 IAC 131.2(2). 567 IAC Chapter 131-State Only 

G14. Excess Emissions and Excess Emissions Reporting Requirements 

1. Excess Emissions. Excess emission during a period of startup, shutdown, or cleaning of control 

equipment is not a violation of the emission standard if the startup, shutdown or cleaning is 

accomplished expeditiously and in a manner consistent with good practice for minimizing emissions. 

Cleaning of control equipment which does not require the shutdown of the process equipment shall be 

limited to one six-minute period per one-hour period. An incident of excess emission (other than an 

incident during startup, shutdown or cleaning of control equipment) is a violation. If the owner or 

operator of a source maintains that the incident of excess emission was due to a malfunction, the owner 

or operator must show that the conditions which caused the incident of excess emission were not 

preventable by reasonable maintenance and control measures. Determination of any subsequent 

enforcement action will be made following review of this report. If excess emissions are occurring, 

either the control equipment causing the excess emission shall be repaired in an expeditious manner or 

the process generating the emissions shall be shutdown within a reasonable period of time. An 

expeditious manner is the time necessary to determine the cause of the excess emissions and to correct 

it within a reasonable period of time. A reasonable period of time is eight hours plus the period of time 

required to shut down the process without damaging the process equipment or control equipment. In 
 Title V Permit 11/10/005 88

the case of an electric utility, a reasonable period of time is eight hours plus the period of time until 

comparable generating capacity is available to meet consumer demand with the affected unit out of 

service, unless, the director shall, upon investigation, reasonably determine that continued operation 

constitutes an unjustifiable environmental hazard and issue an order that such operation is not in the 

public interest and require a process shutdown to commence immediately. 

2. Excess Emissions Reporting 

a. Oral Reporting of Excess Emissions. An incident of excess emission (other than an incident of 

excess emission during a period of startup, shutdown, or cleaning) shall be reported to the appropriate 

field office of the department within eight hours of, or at the start of the first working day following the 

onset of the incident. The reporting exemption for an incident of excess emission during startup, 

shutdown or cleaning does not relieve the owner or operator of a source with continuous monitoring 

equipment of the obligation of submitting reports required in 567-subrule 25.1(6). An oral report of 

excess emission is not required for a source with operational continuous monitoring equipment (as 

specified in 567-subrule 25.1(1) ) if the incident of excess emission continues for less than 30 minutes 

and does not exceed the applicable emission standard by more than 10 percent or the applicable visible 

emission standard by more than 10 percent opacity. The oral report may be made in person or by 

telephone and shall include as a minimum the following: 

i. The identity of the equipment or source operation from which the excess emission originated and the 

associated stack or emission point. 

ii. The estimated quantity of the excess emission. 

iii. The time and expected duration of the excess emission. 

iv. The cause of the excess emission. 

v. The steps being taken to remedy the excess emission. 

vi. The steps being taken to limit the excess emission in the interim period. 

b. Written Reporting of Excess Emissions. A written report of an incident of excess emission shall be 

submitted as a follow-up to all required oral reports to the department within seven days of the onset of 

the upset condition, and shall include as a minimum the following: 

i. The identity of the equipment or source operation point from which the excess emission originated 

and the associated stack or emission point. 

ii. The estimated quantity of the excess emission. 

iii. The time and duration of the excess emission. 

iv. The cause of the excess emission. 

v. The steps that were taken to remedy and to prevent the recurrence of the incident of excess emission. 

vi. The steps that were taken to limit the excess emission. 

vii. If the owner claims that the excess emission was due to malfunction, documentation to support this 

claim. 567 IAC 24.1(1)-567 IAC 24.1(4) 

3. Emergency Defense for Excess Emissions. For the purposes of this permit, an “emergency ” means 

any situation arising from sudden and reasonably unforeseeable events beyond the control of the 

source, including acts of God, which 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 preventive maintenance, 

careless or improper operation or operator error. An emergency constitutes an affirmative defense to an 

action brought for non-compliance with technology based limitations if it can be demonstrated through 

properly signed contemporaneous operating logs or other relevant evidence that: 

a. An emergency occurred and that the permittee can identify the cause(s) of the emergency; 

b. The facility at the time was being properly operated; 
 Title V Permit 11/10/005 89

c. During the period of the emergency, the permittee took all reasonable steps to minimize levels of 

emissions that exceeded the emissions standards or other requirements of the permit; and 

d. The permittee submitted notice of the emergency to the director by certified mail within two 

working days of the time when the emissions limitations were exceeded due to the emergency. This 

notice must contain a description of the emergency, any steps taken to mitigate emissions, and 

corrective actions taken. 567 IAC 22.108(16) 

G15. Permit Deviation Reporting Requirements 

A deviation is any failure to meet a term, condition or applicable requirement in the permit. Reporting 

requirements for deviations that result in a hazardous release or excess emissions have been indicated 

above (see G13 and G14). Unless more frequent deviation reporting is specified in the permit, any 

other deviation shall be documented in the semi-annual monitoring report and the annual compliance 

certification (see G4 and G5). 567 IAC 22.108(5)"b" 

G16. Notification Requirements for Sources That Become Subject to NSPS and NESHAP 

Regulations 

During the term of this permit, the permittee must notify the department of any source that becomes 

subject to a standard or other requirement under 567-subrule 23.1(2) (standards of performance of new 

stationary sources) or section 111 of the Act; or 567-subrule 23.1(3) (emissions standards for 

hazardous air pollutants), 567-subrule 23.1(4) (emission standards for hazardous air pollutants for 

source categories) or section 112 of the Act. This notification shall be submitted in writing to the 

department pursuant to the notification requirements in 40 CFR Section 60.7, 40 CFR Section 61.07,

federally enforceable permit terms and conditions that are monitoring (including test methods), record 

keeping, reporting, or compliance certification requirements. 567 IAC 22.110(2) 

3. Notwithstanding any other part of this rule, the director may, upon review of a notice, require a 

stationary source to apply for a Title V permit if the change does not meet the requirements of subrule 

22.110(1). 567 IAC 22.110(3) 

4. The permit shield provided in subrule 22.108(18) shall not apply to any change made pursuant to 

this rule. Compliance with the permit requirements that the source will meet using the emissions trade 

shall be determined according to requirements of the state implementation plan authorizing the 

emissions trade. 567 IAC 22.110(4) 

5. No permit revision shall be required, under any approved economic incentives, marketable permits, 

emissions trading and other similar programs or processes, for changes that are provided for in this 

permit. 567 IAC 22.108(11) 

G18. Duty to Modify a Title V Permit 

1. Administrative Amendment. 

a. An administrative permit amendment is a permit revision that is required to do any of the following: 

i. Correct typographical errors 

ii. Identify a change in the name, address, or telephone number of any person identified in the permit, 

or provides a similar minor administrative change at the source; 

iii. Require more frequent monitoring or reporting by the permittee; or

or increment analysis. 

iv. Do not seek to establish or change a permit term or condition for which there is no corresponding 

underlying applicable requirement and that the source has assumed in order to avoid an applicable 

requirement to which the source would otherwise be subject. Such terms and conditions include any 

federally enforceable emissions caps which the source would assume to avoid classification as a 

modification under any provision under Title I of the Act; and an alternative emissions limit approved 

pursuant to regulations promulgated under section 112(i)(5) of the Act.; 
 Title V Permit 11/10/005 91

II. NO ADMISSION 

While Holcim agrees to comply with the requirements contained herein, it makes no 

admission as to the Statement of Facts and Conclusions of Law and hereby denies the 

same. 

III. STATEMENT OF FACTS 

 DNR finds as follows: 

1. The 24-hour average PM-10 NAAQS is 150 micrograms per cubic meter 

(ug/m3

). DNR monitored six exceedences of this standard at a previous DNR monitoring 

site located at the intersection of 17th and Quincy in Mason City, Iowa. On May 10, May 

12, and December 29, 1993, this monitoring site recorded 24-hour average PM-10 

concentrations of 174, 172, and 178 ug/m3, respectively. On February 22, 1994, the same 

monitoring site recorded a 24-hour average PM-10 concentration of 160 ug/m3. On 

December 18, 1995, and March 5, 1996, the same monitoring site recorded 24-hour 

average PM-10 concentrations of 239 and 286 ug/m3, respectively. 

 2. Holcim is a cement manufacturer located at 1840 North Federal Avenue in 

Mason City, Iowa, which is north of the previous PM-10 monitoring site at 17th and 

Quincy. Air dispersion modeling of this Holcim facility has been conducted. This 

modeling predicts that Holcim is a contributor to the PM-10 levels monitored. 

3. Holcim is not the sole contributor of PM-10 levels in Mason City and 

other contributors also are being asked to address this concern as well. 

4. DNR and Holcim and other contributors have cooperated in an effort to 

address the levels of PM-10 in Mason City. For that purpose, DNR and Holcim have 

agreed to enter into this Administrative Consent Order.

IV. CONCLUSIONS OF LAW

 DNR concludes as follows: 

1. This Administrative Consent Order is issued pursuant to the provisions of 

Iowa Code sections 455B.134(9) and 455B.138(1), which authorize the Director to issue 

any administrative orders necessary to secure compliance with or prevent a violation of 

Iowa Code chapter 455B, Division II, and the rules promulgated and permits issued 

pursuant thereto, and to prevent, abate, and control air pollution. 

 2. The PM-10 emission sources located at Holcim in Mason City, Iowa, 

include “air contaminant sources” as defined by Iowa Code section 455B.131(2), and 

“stationary sources” and “fugitive dust” sources as defined by 567 Iowa Administrative 

Code (I.A.C.) 20.2. 

 3. According to 567 I.A.C. 28.1, the ambient air quality standards for the 

State of Iowa shall be the National Primary and Secondary Ambient Air Quality 

Standards (NAAQS) located at 40 C.F.R. Part 50, as amended through July 18, 1997. 

 4. According to the provisions of 40 C.F.R. 50.6(a), the primary and 

secondary 24-hour ambient air quality standard for PM-10 is 150 ug/m3

, 24-hour average 

concentration. The standards are attained when the expected number of days per calendar 

year with a 24-hour average concentration above 150 ug/m3, as determined in accordance 

with 40 C.F.R. Part 50, Appendix K, is equal to or less than one. In this case, the 

observed number of days per calendar year with a 24-hour average concentration above 

150 ug/m3, during the period 1993 through 1995, is greater than one, which constitutes a 

violation of this standard. 

 5. An exceedence of the NAAQS for PM-10 constitutes “air pollution” as 

defined by Iowa Code section 455B.131(3). 

 6. In accordance with the provisions of Iowa Code section 455B.134(9), the 

Director shall issue orders consistent with the rules to cause the abatement or control of 

air pollution. 

7. According to the provisions of 567 I.A.C. 22.1(1) and 567 I.A.C. 22.1(3), 

the owner or operator of a stationary source shall obtain a permit to install or alter 

equipment or control equipment unless otherwise exempt. Any modifications occurring 

as a result of this consent order and subject to the provisions of 567 I.A.C. chapter 22 

shall require a construction permit or shall meet the requirements of a construction permit 

exemption contained in the provisions of 567 I.A.C. 22.1(2). 

8. The provisions of 567 I.A.C. 23.3(2)”c”(1), provide, in relevant part, that 

all persons, with certain exceptions, shall take reasonable precautions to prevent the 
IOWA DEPARTMENT OF NATURAL RESOURCES

ISSUED TO: Holcim (US), Inc.

101 

discharge of visible emissions of fugitive dusts beyond the lot line of the property on 

which the emissions originate. “Reasonable precautions” are defined in this rule. 

V. ORDER 

 THEREFORE, DNR orders and HOLCIM agrees to the following: 

 1. A fenceline, of a type designed to preclude public access to the facility 

property, shall be maintained as depicted in Exhibit “A”, which is attached to this 

Administrative Consent Order and by this reference made a part hereof. “No 

Trespassing” signs shall be maintained at both ends of the gap in the fence coverage 

along the western facility boundary, as identified in Exhibit “A”. Twenty-four hour 

security surveillance shall be maintained of the facility boundaries to further restrict 

public access. DNR acknowledges that as of the date of this Administrative Consent 

Order, the facility maintains a fenceline and has installed “No Trespassing” signs meeting 

the requirements of this paragraph. 

 

 2. Within 60 days of the effective date of this Administrative Consent Order, 

Holcim shall submit to DNR air quality construction permit applications which include 

the emission rates and hours of operation listed in Exhibit “B.” By this reference, Exhibit 

“B” is made a part hereof. Any required modifications to the sources shall be completed 

within 60 days of the issuance of the permits (unless specifically stated otherwise in the 

permit). 

 3. The emission sources listed in Exhibit “C” shall be limited to the daily and 

calendar year throughputs listed in Exhibit “C.” By this reference, Exhibit “C” is made a 

part hereof. The total daily throughput, and daily throughput rates for each of the sources 

listed in Exhibit “C” shall be entered in a daily log to demonstrate compliance with the 

daily throughput limits. Rolling total daily throughput rates shall be maintained to 

demonstrate compliance with the total calendar year throughput rates listed in Exhibit 

“C”. The daily logs shall be retained for a period of two years following the date of such 

entries and shall be made available to the DNR upon request. This record keeping shall 

be an on-going requirement and shall not terminate. Record keeping shall commence 

within 30 days of the effective date of this Administrative Consent Order. 

 4. Storage Piles: 

 (i). Within 60 days of the effective date of this Administrative Consent Order, 

Holcim shall locate the storage pile bases as designated in Exhibit “D”, except as

(ii). Notwithstanding the requirements of paragraph 4(i), Holcim may operate 

temporary piles of materials (not identified on Exhibit “D”) that result from maintenance 

and other similar activities. No such temporary pile shall be maintained for more than 

one 24-hr period.

(iii). Notwithstanding the requirements of paragraph 4(i) and 4(ii), Holcim may 

maintain temporary piles of overflow raw materials (excluding fuel) and product, not 

identified on Exhibit “D”, that may result from unforeseen and unplanned operating 

conditions or problems. Holcim shall take all reasonable measures to limit the size of any 

such pile and the fugitive emissions that result therefrom. No more than two such 

temporary piles may exist at one time. Holcim shall take reasonable measures to remove 

any such pile as soon as practicable, but in no case shall any such temporary pile be 

maintained for more than three (3) months. Holcim shall maintain records that include 

the pile location, planned or actual pile size, pile material content, and the planned 

removal date, for each pile. The records shall be retained for a period of two years 

following the date of the above entries and shall be made available to the DNR upon 

request. This record keeping shall be an on-going requirement and shall not terminate. 

5. Holcim shall implement speed controls designed to ensure that the average 

speed of the haul trucks on the M3 limestone haul road does not exceed 20 miles per 

hour. The speed controls shall consist of speed limit signs and stop signs along the route. 

 6. Unpaved Haul Road Trip Restrictions:

(i). The maximum number or round trips per day and per calendar year on the M3 

limestone haul road shall be limited to the values listed below. 

Truck Capacity 

(tons of material) 

Maximum Number of 

Round Trips per Day 

Maximum Number of 

Round Trips per Year 

25 40 8,000

130 77 27,043

(ii). The number of round trips per day on the M3 limestone haul road shall 

be entered in a daily log to demonstrate compliance with this requirement. The daily logs 

shall be retained for a period of two years following the date of such entries and shall be 

made available to the DNR upon request. This record keeping shall be an on-going 

requirement and shall not terminate. 

(iii). Traffic on the unpaved portion of the M4 haul road shall be limited to 

scraper travel only, with the exception of dozer and compactor vehicles used to maintain 

the pile integrity and size limitation. The maximum number of round trips per day and 

per calendar year on the M4 haul road shall be limited to 200 and 70,080 trips, 

respectively. The scraper capacity shall be limited to 27 tons of material per trip. These 

maximum numbers of round trips and the scraper capacity shall not be increased unless a 

dispersion modeling analysis, acceptable to the DNR, is submitted to demonstrate that 

compliance with the PM-10 NAAQS will be maintained.

Administrative Consent Order 

ISSUED TO: Holcim (US), Inc.

103 

 7. Control of Fugitive Emissions from Unpaved Haul Roads: 

(i). Fugitive emissions from the M3 limestone haul road shall be controlled by 

applying a chemical dust suppressant. A control efficiency of 95 percent shall be 

maintained on the entire length of both segments of the limestone haul road. The M3 

limestone haul road is approximately 30 feet wide and approximately 2.9 miles long, 

giving it a total area of approximately 51,040 square yards. Thus, approximately 2,552 

gallons of the selected chemical dust suppressant shall be applied no less frequently than 

once every other week to maintain the established ground inventory. This equates to 0.05 

gallons of chemical dust suppressant per square yard, or a manufacturer’s equivalent 

application to achieve the 95 percent control efficiency. Different manufacturer’s 

materials have different applications to achieve 95 percent control. Documentation 

supporting a different concentration will be maintained onsite by Holcim and submitted 

to the DNR, as required. 

(ii). Fugitive emissions from the unpaved portion of the M4 haul road shall be 

controlled by applying a chemical dust suppressant. Applications of the selected 

chemical dust suppressant and the record keeping requirements described below shall 

begin within 30 days of the effective date of this Administrative Consent Order. A 

control efficiency of 95 percent shall be maintained on the unpaved portion of the M4 

haul road. The unpaved portion of the M4 haul road is approximately 30 feet wide and 

approximately 0.19 miles long, giving it a total area of approximately 3,344 square yards. 

Approximately 167 gallons of the selected chemical dust suppressant shall be applied no 

less frequently than once every other week to maintain the established ground inventory. 

This equates to 0.05 gallons of chemical dust suppressant per square yard, or a 

manufacturer’s equivalent application to achieve the 95 percent control efficiency. 

Different manufacturer’s materials have different applications to achieve 95 percent 

control. Documentation supporting a different concentration will be maintained onsite by 

Holcim and submitted to the DNR, as required. 

(iii). If the selected chemical dust suppressant can not be applied because the 

ambient air temperature (as measured at the facility during daylight operating hours) will 

be less than 350

 F (1.70 C) or conditions due to weather, in combination with the 

application of the chemical dust suppressant, could create hazardous driving conditions, 

then the chemical dust suppressant application shall be postponed and applied as soon 

after the scheduled application date as the conditions preventing the application have 

abated. Records of the applications shall be maintained and shall include the dates of 

each application, the chemical dust suppressant used, the application intensity 

(gals./sq.yd.), dilution ratio, the operator’s initials, and documentation of road and 

weather conditions, if necessary. If the selected chemical dust suppressant is not applied 

as planned, then the records should so indicate and provide an explanation. The records 

shall be retained for a period of two years following the date of the above entries and 

shall be made available to the DNR upon request. This record keeping shall be an ongoing requirement and shall not terminate. 

 (iv). In the event Holcim does not use (or plan to use) haul road M3 and the 

unpaved portion of haul road M4 for fourteen (14) days or more, Holcim shall not be 

required to apply the chemical dust suppressant as provided in paragraph 7(i) and 7(ii), 
IOWA DEPARTMENT OF NATURAL RESOURCES 

Administrative Consent Order 

ISSUED TO: Holcim (US), Inc.

respectively. Prior to using such haul road again, however, an application (at the biweekly rate) shall be made subject to the conditions of paragraph 7(iii). 

8. Paved Haul Road Trip Restrictions: 

The maximum number of round trips per day and per calendar year on the M1, M2, M4, 

and M5 paved haul roads, for all haul trucks, combined, shall be limited to the values 

listed below. 

Haul Road 

Maximum Number of 

Round Trips per Day 

Maximum Number of 

Round Trips per Year 

M1 96 17,520

M2 312 43,800

M4 (paved portion) 192 70,080

M5 192 26,280

The number of round trips per day on the M1, M2, the paved portion of M4, and the M5 

haul roads shall be entered into a daily log to demonstrate compliance with the maximum 

number of round trips per day limitation. A daily rolling count of the total number of 

round trips per day on M1, M2, the paved portion of M4, and M5 shall be maintained to 

demonstrate compliance with the maximum number of round trips per year limitation. 

The daily logs shall be retained for a period of two years following the date of such 

entries and shall be made available to the DNR upon request. This record keeping shall 

be an on-going requirement and shall not terminate. 

 

9. Control of Fugitive Emissions from Paved Haul Roads: 

(i). Fugitive emissions of the paved haul roads M1, M2, M4, and M5 shall be 

controlled to an effective control efficiency of 80 percent by water flushing followed by 

sweeping. The control efficiency of 80 percent shall be achieved by water flushing 

followed by sweeping haul roads M1, M2, the paved portion of M4, and M5 once per 

day. The following table contains the approximate size of each haul road in square yards 

and the approximate amount of water to be applied to each road in each application. The 

water quantities are based on a spray rate of approximately 0.23 gallons per square yard. 

Paved Haul Road Road Area 

(sq. yards) 

Approximate Water 

Application Rate 

(gals. of water) 

M1 5,280 1214

M2 6,688 1538

M4 (paved portion) 2,112 486

M5 6,336 1,457

(ii). If water flushing followed by sweeping can not be accomplished because the 

ambient air temperature (as measured at the facility during daylight operating hours) will 

be less than 350

 F (1.70 C) or conditions due to weather, in combination with the 

application of the water, could create hazardous driving conditions, then the water 
IOWA DEPARTMENT OF NATURAL RESOURCES 

Administrative Consent Order 

ISSUED TO: Holcim (US), Inc.

105 

flushing and sweeping shall be postponed and accomplished as soon after the scheduled 

date as the conditions preventing the application have abated. Additionally, water 

flushing and sweeping need not occur when a rain gage located at the site indicates that at 

least 0.2 inches of precipitation (water equivalent) has occurred within the preceding 24-

hour time period or the paved road(s) will not be used on a given day. 

(iii). Records of the applications shall be maintained and shall include the 

dates of each application, the amount of water applied, the areas treated, and the 

operator’s initials. If water is not applied when scheduled due to the conditions specified 

in Paragraph 9(ii) above, the conditions which prevented such application, or made such 

application unnecessary, shall be documented. The records shall be retained for a period 

of two years following the date of the above entries and shall be made available to the 

DNR upon request. This record keeping shall be an on-going requirement and shall not 

terminate. 

10. Holcim shall maintain records of the number coal cars unloaded daily at 

the Coal Dump Shed. These records shall include the unloading dates and the load 

capacity (tons) of each coal car unloaded. The records shall be retained for a period of 

two years following the date of the above entries and shall be made available to the DNR 

upon request. This record keeping shall be an on-going requirement and shall not 

terminate. 

11. Holcim shall submit to the Mason City DNR Field Office #2 written

AFFECTED SOURCES – Definitions and nomenclature 

Overview of the portland cement production process 

The production of cement is a five-step process: 1) raw meal preparation system, 

2) clinker manufacture system, 3) clinker cooler system, 4) cement manufacture 

system, 5) packing, dispatch, distribution and blending. Mining or quarrying 

obtains the majority of raw materials used in cement production. The raw 

materials are ground and proportioned so that the mixture or “kiln feed” has the 

desired fineness and chemical composition for delivery to the pyroprocessing 

system. 

The pyroprocessing takes place in the kiln where complex chemical reactions 

transform the kiln feed into clinker. From the kiln, the clinker is cooled from 

approximately 1,600 to 2,000 °F to about 200 to 450 °F in the clinker cooler. The 

clinker is then ground with additives to produce cement. The cement, which can 

be blended, is then distributed out of the plant by bag, bulk truck, or bulk rail. 

Equipment nomenclature and grouping 

For production tracking purposes, the cement manufacturing process is divided 

into functional locations. Each main task of the plant has its own functional 

location (e.g., raw meal preparation). The equipment number system is also based 

on functional locations. 

Each piece of equipment is assigned an individual six-digit number (called a 

Holcim Asset Code number (HAC#)). The first three numbers locate the piece of 

equipment in the process. The first digit is the main cost center; the second 

number is the group number; and the third is the sequential number by process 

line. The last three digits of the HAC# describe exactly what piece of equipment 

it is. 

The affected sources regulated by this O&M Plan are organized by functional 

locations as well. The affected source groupings and associated HAC# are listed 

in Table 2-1. Also included in Table 2-1 are the affected source types included in 

each affected source system.

Guidelines for Naming Affected Sources 

Naming of affected sources in a consistent fashion is aided by the development of 

naming guidelines. Equipment identified in 40 CFR 63.1340(b) were named 

according to the following guidelines: 

1. The transfer from one conveying system to another conveying system is an affected source 

2. The transfer from a piece of process equipment to a conveying system is an 

affected source 

3. The transfer from a storage bin or hopper is considered an affected source 

4. Valves (tipping and some rotary) and gates (diverter, slide, knife) within a transfer are 

considered part of the affected source 

5. Weigh feeders and volumetric (e.g., vibrating) feeders are separate conveying systems and, 

therefore, transfers to and from the feeder would be considered an affected source 

6. Rotary valves that are used to meter material are considered feeders and are treated 

identical to weigh and volumetric feeders 

7. Bag filters are identified as pollution control devices by their HAC#. 

8. Valves (rotary, flap, slide gates) on the material discharge hopper of a bag filter or cyclone are 

considered to be part of the bag filter or cyclone; therefore, the bag filter or cyclone will be the 

originating point in describing the transfer point for material collected in the bag filter or 

cyclone to a subsequent conveyor or material storage bin. 

9. Major pieces of process equipment, e.g., the raw mill, that are called out as affected sources 

by the regulation are identified as affected sources by its HAC#. 

10. Direct (enclosed) transfer points are identified by the HAC# of the upstream (discharging) 

conveyor or equipment in the process flow. 

11. Direct (open) conveyor-to-conveyor transfer points are identified with the upstream 

conveyor. 

12. Transfer points that have a transfer chute are identified by the HAC# of the transfer chute. 

13. Transfer points from bins to feeders or conveyors are identified by the feeder or conveyor 

HAC# unless there is a transfer chute between the bin and feeder, in which case, the 

transfer point is identified by the transfer chute HAC#. 

14. The transfer from one conveying system or piece of process equipment to two subsequent 

pieces of equipment through the use of a diverter gate creates two affected sources. These 

sources are identified by the chute immediately preceding the destination of the transfer. 

15. A material storage bin is identified as an affected source by its HAC#. 

16. Transfer points to waste, storage piles or transport vehicles are identified by the last piece of 

equipment in the process flow to which an HAC# has been assigned, e.g., the loading chute 

for cement trucks. 

17. Ducts that serve to transfer relatively large quantities of in-process materials, i.e., ground 

coal and raw mix, are considered to be enclosed conveying systems. For identification 

purposes, the conveyor transfer points in these systems are identified by the duct HAC#.

Conveying System Transfer Points – Additional Clarification 

All conveyor system transfer points (CSTPs) are affected sources according to PC 

MACT and are included in the affected source systems. Further, CSTPs have 

their own specific monitoring requirements according to their placement and 

control. As a result, transfer points are generally grouped into the following three 

categories: 

Group 1: Totally enclosed conveying system transfer points – These transfers 

are enclosed on all sides, top, and bottom. Method 22 visible emissions 

monitoring does not apply to any totally enclosed CSTP (40 CFR 

63.1350(a)(4)(v)).

Group 2: Partially enclosed or unenclosed conveying system transfer points – 

These transfers have at least one side, top, or bottom that is open. A monthly 

Method 22 visible emissions monitoring test must be conducted for a partially 

enclosed or unenclosed CSTP (40 CFR 63.1350(a)(4)(i)). As an alternative, if 

these affected sources are located within a building, the building itself can be 

tested (40 CFR 63.1350(a)(4)(vi)). 

Group 3: Partially enclosed or totally enclosed CSTPs with an APCD – These 

CSTPs are ducted to an APCD. Consequently, a monthly Method 22 test will be 

conducted at the APCD only. 

Group 4: Facility sources not subject to PC MACT, 40 CFR Part 63, Subpart 

LLL that are required to be maintained in a Facility Operation and Maintenance 

Plan for Title V Purposes. 

Transfer points associated with materials that are dust free, such as tires or coal, 

are not considered in the listing of CSTPs.

Maintenance System 

Following is an overview of the plant preventative maintenance program and associated tracking 

system. 

Holcim uses historical maintenance records, vendor manuals for specific pieces of equipment, 

and/or the results of a Failure Mode Effects Analysis (FMEA) as guidelines for prioritizing 

maintenance and preventing failures of general types of process equipment at the plant. 

Historical records may include information such as the performance of the equipment. Vendor 

manuals for equipment may also provide suggested preventative maintenance tasks and 

associated frequencies. The FMEA system lists the various possible ways the equipment might 

fail (referred to as functional failures), identifies causes of the failures (referred to as failure 

modes), and recommends actions that could be taken to resolve the specific failures. The FMEA 

was developed for an idealized, generic cement plant with the goal of preventing downtime or 

malfunctions. Therefore, the FMEA is a useful aid to prioritize PM tasks and to suggest options 

for repairs; however, the PM interval recommendations contained in the FMEA are only 

guidelines. 

Preventive maintenance and inspections at the facility are often managed using a plant data 

management system that generates preventive maintenance routines (PMRs) at predetermined 

intervals. A PMR is an example of a PM inspection tour that could be assigned to plant staff. In 

addition, maintenance work orders can be generated when non-routine preventive maintenance 

issues are identified during periodic inspections by staff. 

Maintenance staff is responsible for ensuring that each affected source at the plant is inspected 

on a reasonable basis. Unless required on a more frequent basis, a PMR will typically occur on 

at least an annual basis.

O&M plans by plant system (grouping of equipment) 

Following are the specific O&M Plans for each of the plant’s systems. 

Raw Meal Preparation System (Raw Mills and Dryer) 

PROCESS DESCRIPTION

The raw meal preparation system combines the drying, blending and 

grinding of the raw materials to form the kiln feed. Raw material is taken 

from the on-site quarry and transported to the mill feed system. Corrective 

materials used to obtain quality standards are received by truck or rail and 

sometimes dried depending on the moisture content and transported to 

the mill feed system. Within the mill feed system, the raw materials are 

heated and dried, as they are being ground in the ball mill. After the ball 

mill, the raw meal product is homogenized and transported to the clinker 

manufacture system. The dust generated in the raw milling process is 

removed by baghouse PMCDs. 

The reverse-air baghouses remove the dust in the air stream. The dust is captured 

by the bags. The bags are divided up into compartments, so that each 

compartment can be taken off line individually. At specified intervals, a 

compartment of bags is cleaned by forcing air in from the other direction to 

remove material from the bags. The collected dust is returned to the process, sold 

as by-product, or removed for disposal. 

The pulse jet baghouses remove the dust in the air stream. The dust is captured 

by the bags. The dust does not penetrate the bags; rather it remains as a deposit 

on the bags’ outside surface. At specified intervals, as needed, a cleaning cycle is 

initiated in which the bags are automatically and sequentially cleaned. To 

facilitate this action, a pulse valve delivers a burst of compressed air through the 

bags in reverse direction to remove material from the bags. The collected 

material is returned to the process, sold as by-product, or removed for disposal. 

The electro static precipitator (ESP) removes the dust in the air stream. The air 

stream passes through the ESP where the particles become electrically charged. 

These particles collect on negatively-charged hanging plates. Accumulated 

particulate is removed by rapping the collecting plates. The collected material is 

returned to the process, sold as by-product, or removed for disposal. 

The HAC code numbers for the raw meal preparation system range from 332-BC1 

to 41B-AS1. This includes the following affected source types: the ball mills, 

conveying system transfer points, storage bins, and baghouse PMCDs. 

Table 4.1-1 provides a list of the affected sources in the system.

MAINTENANCE PROCEDURES FOR THE RAW MEAL PREPARATION 

SYSTEM

Preventive maintenance (PM) at the facility is conducted in accordance 

with Historical maintenance records, vendor manuals for specific pieces of 

equipment, and/or the results of a Failure Mode Effects Analysis (FMEA) 

which serves as a guideline for prioritizing maintenance and preventing 

failures of general types of process equipment at the plant. Refer to 

Section 3.0 for details. 

CORRECTIVE ACTION PROGRAM

A corrective action program has been developed and implemented to 

diagnose, repair, and document equipment malfunctions. Corrective action 

will be initiated as soon as practicable after a malfunction is identified and will 

be completed within a reasonable time after its initiation. The corrective 

action program includes performing the following steps to implement any 

corrective action. 

1) Identification that a malfunction is occurring, or has occurred, that may have caused, 

or is causing, excess emissions. 

2) A maintenance notification/malfunction form is initiated 

3) A work order is generated, if necessary 

4) The repair or necessary process adjustment is completed 

5) If the equipment was stopped in order to complete the repair, it is brought back into 

operation. The operation is observed to ensure that it starts and continues to operate 

as expected. 

6) The work order/maintenance notification/malfunction form is closed out by inputting 

the following information: 

a. The symptom of the malfunction 

b. The cause of the malfunction 

c. The start and end time for the malfunction, and 

d. The description of the repair completed

CLINKER MANUFACTURE System (KILN) 

PROCESS DESCRIPTION

Kilns are rotating steel tubes lined with refractory material in which the raw meal 

is transformed into clinker. The kiln is inclined and rotates with hot combustion 

gases flowing countercurrent to the material flow. Heat is transferred from the 

flame and hot gases to heat the material to approximately 2,700°F to 3,000°F 

(1,400 °C to 1,600 °C), which drives the complex chemical reactions of clinker 

production. The dust generated in the clinker manufacture system is removed by 

baghouse PMCDs. 

Tubular bags filter the dust laden kiln exhaust gas. The reverse-air baghouses 

remove the dust in the gas air stream. The reverse-air baghouses are 

compartmentalized to allow for isolation during cleaning. The gas enters through 

the bottom of the collector and is directed to the filter bags. The dust is collected 

on the inside of the vertically hanging bags, while the clean air exits through the 

outside of the bag. During the cleaning cycle, the flow of dirty air is stopped in a 

compartment. The compartment is then pressurized with a low-pressure flow of 

clean air. Dust is removed by allowing the bags to collapse, which causes the 

dustcake to break and fall into the hopper. The collected dust is returned to the 

process, sold as by-product, or removed for disposal. 

The HAC code numbers for the clinker manufacture system range from 4XXXXX to LXX-XXX. This includes the following affected source types: the kiln 

system, numerous conveying system transfer points, and a few storage bins. In 

addition, the clinker manufacture system includes several baghouse PMCDs. 

Table 4.2-1 provides a list of the affected sources in the system.

OPERATION PROCEDURES FOR THE CLINKER MANUFACTURE SYSTEM

The operation of the clinker manufacture system is conducted in accordance with 

the equipment vendor and/or in-house guidelines. The detailed procedures for 

clinker manufacture system operation and the annual combustion system 

inspections are contained in Standard Operating Procedure (SOP) SOP-KL2 SOPKL3 and SOP-KLA. During clinker manufacture system operation, key process 

parameters are monitored and recorded using data loggers. The detailed 

procedures for continuous monitoring system operation associated with the 

clinker manufacture system are contained in the Continuous Monitoring System 

Standard Operating Procedures (CMS SOP) CMSP-001. 

MONITORING REQUIREMENTS FOR THE CLINKER MANUFACTURE 

SYSTEM

Table 4.2-2 contains the operating and monitoring requirements for the various 

affected source types included in the clinker manufacture system. A continuous 

monitoring system requirement flow chart for COMS and Thermocouples is 

provided as Figure 4-4. The monitoring requirement procedure flow charts for 

CSTPs and storage bins, either independently or in a structure, are provided as 

Figures 4-2 and 4-3, respectively. 

ALTERNATIVE MONITORING PROCEDURE

If the required continuous monitoring system (i.e., main stack COMs and PMCD 

inlet thermocouple) for the clinker manufacturing system is malfunctioning or 

data is not being recorded for an extended period of time while the system 

continues to operate, in addition to initiating corrective action to repair the 

monitor, alternative monitoring will be initiated in order to demonstrate that the 

source remained in compliance during the period where data is not available. For 

example, when the main kiln stack COMs is malfunctioning for more than 24 

hours, a 30-minute Method 9 visual emissions test will be performed each day 

that COMs data is invalid or unavailable while the kiln is operating. 

In the case of a temperature monitor at the inlet of the main air pollution control 

device, if the temperature sensor is malfunctioning or data is not being recorded 

for more than 24 hours, alternate indicators of temperature control at the 

particulate matter control device will be monitored and documented in order to 

demonstrate compliance.

MAINTENANCE PROCEDURES FOR THE CLINKER MANUFACTURE SYSTEM

Preventive maintenance (PM) at the facility is conducted in accordance with 

Historical maintenance records, vendor manuals for specific pieces of equipment, and/or the 

results of a Failure Mode Effects Analysis (FMEA) which serves as a guideline for prioritizing 

maintenance and preventing failures of general types of process equipment at the plant. Refer 

to Section 3.0 for details. 

Annual Combustion System Inspection 

The annual combustion system inspection is included as apart of the PMR program in the SAP 

system. The detailed procedures are contained in SOP-KLA. 

CORRECTIVE ACTION PROGRAM

A corrective action program has been developed and implemented to diagnose, repair, and 

document equipment malfunctions. Corrective action will be initiated as soon as practicable 

after a malfunction is identified and will be completed within a reasonable time after its 

initiation. 

The corrective action program includes performing the following steps to implement any 

corrective action. 

1) Identification that a malfunction is occurring, or has occurred, that may have caused, or is causing, 

excess emissions. 

2) A maintenance notification/malfunction form is initiated 

3) A work order is generated, if necessary 

4) The repair or necessary process adjustment is completed 

5) If the equipment was stopped in order to complete the repair, it is brought back into operation. The 

operation is observed to ensure that it starts and continues to operate as expected. 

6) The work order/maintenance notification/malfunction form is closed out by inputting the following 

information: 

a. The symptom of the malfunction 

b. The cause of the malfunction 

c. The start and end time for the malfunction, and 

d. The description of the repair completed

CLINKER COOLER SYSTEM 

PROCESS DESCRIPTION

The function of the clinker cooler system is to cool the clinker to make it possible to handle 

with conventional conveying equipment. The clinker is cooled from approximately 1,600 to 

2,200 °F (870 to 1,200 °C) to about 250 to 450 °F (120 to 230 °C). The dust from the clinker 

coolers is removed by baghouse PMCDs. 

The cooler exhaust fan pulls the air into the baghouses, where the gas is filtered by tubular 

bags. The dust in the gas does not penetrate the bags; rather it remains as a deposit on the bags’ 

outside surface. At specified intervals, as needed, a cleaning cycle is initiated in which the 

bags are automatically and sequentially cleaned. To facilitate this action, a pulse valve delivers 

a burst of compressed air through the bags in reverse direction to remove material from the 

bags. The collected material is returned to the process, sold as by-product, or removed for 

disposal. 

The HAC numbers for the clinker cooler systems include 47X-XXX and 49X-XXX. This 

includes the following affected source types: the clinker cooler, conveying system transfer 

points, storage bins, and baghouse PMCDs. 

Table 4.3-1 provides a list of the affected sources in the system.

OPERATION PROCEDURES FOR THE CLINKER COOLER SYSTEM

The operation of the clinker cooler system is conducted in accordance with the equipment 

vendor and/or in-house guidelines. The detailed procedures for clinker cooler system operation 

are contained in the Standard Operating Procedures SOP-KL2 and SOP-KL3. During the 

clinker cooler operation, opacity is measured with a continuous opacity monitor (COM). 

Detailed procedures for continuous monitoring system operation associated with the clinker 

cooler are contained in the Continuous Monitoring System Standard Operating Procedure 

(CMS SOP) CMSP-001. 

MONITORING REQUIREMENTS FOR THE CLINKER COOLER SYSTEM

Table 4.3-2 contains the operating and monitoring requirements for the various affected source 

types included in the clinker cooler system. A continuous monitoring system requirement flow 

chart for COMS is provided as Figure 4-4. The monitoring requirement procedure flow charts 

for CSTPs and storage bins, either independently or in a structure, are provided as Figures 4-2 

and 4-3, respectively.

ALTERNATIVE MONITORING PROCEDURE

If the required continuous monitoring system for the clinker cooler system (i.e., clinker cooler 

stack COMs) is malfunctioning or data is not being recorded for an extended period of time 

while the system continues to operate, in addition to initiating corrective action to repair the 

monitor, alternative monitoring will be initiated in order to demonstrate that the source 

remained in compliance during the period where data is not available. For example, when the 

clinker cooler COMs is malfunctioning for more than 24 hours, a 30 minute Method 9 visual 

emissions test will be performed each day that the COMs data is invalid or unavailable. 

MAINTENANCE PROCEDURES FOR THE CLINKER COOLER SYSTEM

Preventive maintenance (PM) at the facility is conducted in accordance with 

historical maintenance records, vendor manuals for specific pieces of equipment, and/or the 

results of a Failure Mode Effects Analysis (FMEA) which serves as a guideline for prioritizing 

maintenance and preventing failures of general types of process equipment at the plant. Refer 

to Section 3.0 for details. 

CORRECTIVE ACTION PROGRAM

A corrective action program has been developed and implemented to diagnose, repair, and 

document equipment malfunctions. Corrective action will be initiated as soon as practicable 

after a malfunction is identified and will be completed within a reasonable time after its 

initiation. 

The corrective action program includes performing the following steps to implement any 

corrective action. 

1) Identification that a malfunction is occurring, or has occurred, that may have caused, or is causing, 

excess emissions.

Cement Manufacture System (Finish MillS) 

PROCESS DESCRIPTION

The finish milling process grinds the clinker into a fine powder. Additives are added during the 

grinding to produce the final product. Baghouses filled with bags, filter the finish mill air stream. 

A pulse-jet baghouse is designed with internal frame structures called cages. The dust does not 

penetrate the bags and collects on the bags’ outside surface and forms a dustcake. At specified 

intervals, the dustcake is periodically removed by a pulse jet of compressed air into the bag that 

causes a sudden expansion of the bag. Primarily inertial forces remove the dust when the bag 

reaches its maximum expansion. The collected material is returned to the process, sold as byproduct, or removed for disposal. 

A reverse-air baghouse is compartmentalized to allow for isolation during cleaning. The air 

stream enters through the bottom of the collector and is directed to the filter bags. The dust is 

collected on the inside of the vertically hanging bags, while the clean air exits through the 

outside of the bag. During the cleaning cycle, the air stream is stopped from entering a 

compartment. The compartment is then pressurized with a low-pressure flow of clean air. 

Dust is removed by allowing the bags to collapse, which causes the dustcake to break and fall 

into the hopper. The collected material is returned to the process, sold as by-product, or 

removed for disposal. 

The HAC code numbers for the cement manufacture system range from 52X-XXX to L10-

BCX. This includes the following affected source types: the finish mills, conveying system 

transfer points, storage bins, and baghouse PMCDs. 

Table 4.4-1 provides a list of the affected sources in the system.

MAINTENANCE PROCEDURES FOR THE CEMENT MANUFACTURE SYSTEM

Preventive maintenance (PM) at the facility is conducted in accordance with historical 

maintenance records, vendor manuals for specific pieces of equipment, and/or the 

results of a Failure Mode Effects Analysis (FMEA) which serves as a guideline for 

prioritizing maintenance and preventing failures of general types of process equipment 

at the plant. Refer to Section 3.0 for details. 

CORRECTIVE ACTION PROGRAM

A corrective action program has been developed and implemented to properly diagnose, 

repair, and document equipment malfunctions. Corrective action will be initiated within 1 

hour after a malfunction is identified and will be completed within a reasonable time after 

its initiation. 

The corrective action program includes performing the following steps to implement any 

corrective action. 

1) Identification that a malfunction is occurring, or has occurred, that may have caused, or is causing, 

excess emissions. 

2) A maintenance notification/malfunction form is initiated 

3) A work order is generated, if necessary 

4) The repair or necessary process adjustment is completed 

5) If the equipment was stopped in order to complete the repair, it is brought back into operation. The 

operation is observed to ensure that it starts and continues to operate as expected. 

6) The work order/maintenance notification/malfunction form is closed out by inputting the following 

information: 

a. The symptom of the malfunction 

b. The cause of the malfunction 

c. The start and end time for the malfunction, and 

d. The description of the repair completed

PACKING, DISPATCH, AND DISTRIBUTION 

PROCESS DESCRIPTION

This section is applicable to the shipping of cement products in bulk via bags, rail or truck from 

silos 6007 through 6066. There are several subsystems that withdraw bulk cement or grancem 

from railcars, blend from storage silo to storage silo, withdraw bulk cement from the storage 

silos, transport the cement to several loading points and deposit the cement in the transport 

vehicle. 

The major components of the systems include screw conveyors, material pumps, airslides, 

bucket elevators, loading spouts and packers. 

The HAC code numbers for the packing, dispatch, and distribution system range from 61XXXX to 6EX-XXX. This includes the following affected source types: conveying system 

transfer points, storage bins, and baghouse PMCDs. 

Table 4.5-1 provides a list of the affected sources in the system.

(i) The recorder response range must include zero and 1.5 times either of the 

 average temperatures established according to the requirements in (b)(3)(iv) of 

 Performance testing requirements. 

(ii) The reference method must be a National Institute of Standards and Technology 

 calibrated reference thermocouple-potentiometer system or alternate reference, 

 subject to approval by the Administrator. 

(2) The owner or operator shall monitor and continuously record the temperature of the 

exhaust gases from the kiln, in-line kiln/raw mill and alkali bypass, if applicable, at the inlet 

to the kiln, in-line kiln/raw mill and/or alkali bypass PMCD. 

(3) The three-hour rolling average temperature shall be calculated as the average of 180 

 successive one-minute average temperatures. 

(4) Periods of time when one-minute averages are not available shall be ignored when 

 calculating three-hour rolling averages. When one-minute averages become 

 available, the first one-minute average is added to the previous 179 values to calculate 

 the three-hour rolling average. 

(5) When the operating status of the raw mill of the in-line kiln/raw mill is changed from 

off to on, or from on to off the calculation of the three-hour rolling average temperature 

must begin anew without considering previous readings. 
 196 

 

(6) The calibration of all thermocouples and other temperature sensors shall be verified at 

least once every three months. 

(g) The owner or operator of any kiln or in-line kiln/raw mill subject to a D/F emission limit 

 under this subpart shall conduct an inspection of the components of each kiln or in-line 

 kiln/raw mill at least once per year. 

(h) The owner or operator of an affected source subject to a limitation on opacity under 

Standards for new and reconstructed raw material dryers, and Standards for affected sources other 

than kiln;, in-line kiln/raw mills; clinker coolers; new and reconstructed raw material dryers; and 

raw and finish mills shall monitor opacity in accordance with the operation and maintenance plan 

developed in accordance with paragraph (a) of this section. 

(i) The owner or operator of an affected source subject to a particulate matter standard under 

Standards for kilns and in-line kiln/raw mills shall install, calibrate, maintain and operate a 

particulate matter continuous emission monitoring system (PM CEMS) to measure the particulate 

matter discharged to the atmosphere. The compliance deadline for installing the PM CEMS and all 

requirements relating to performance of the PM CEMS and implementation of the PM CEMS is 

deferred pending further rulemaking. 

(j) An owner or operator may submit an application to the Administrator for approval of 

 alternate monitoring requirements to demonstrate compliance with the emission standards of 

 this subpart, except for emission standards for THC, subject to the provisions of paragraphs 

 (j)(1) to (j)(6) of this section. 

(1) The Administrator will not approve averaging periods other than those specified in 

this section, unless the owner or operator documents, using data or information, that the 

longer averaging period will ensure that emissions do not exceed levels achieved during the 

performance test over any increment of time equivalent to the time required to conduct 

three runs of the performance test. 

(2) If the application to use an alternate monitoring requirement is approved, the owner 

or operator must continue to use the original monitoring requirement until approval is 

received to use another monitoring requirement. 

(3) The owner or operator shall submit the application for approval of alternate 

 monitoring requirements no later than the notification of performance test. The 

 application must contain the information specified in paragraphs (j)(3)(i) through 

 (j)(3)(iii) of this section: 

 (i) Data or information justifying the request, such as the technical or economic 

 infeasibility, or the impracticality of using the required approach; 

(ii) A description of the proposed alternative monitoring requirement, including the 

 operating parameter to be monitored, the monitoring approach and technique, the 

 averaging period for the limit, and how the limit is to be calculateed; and 

(iii) Data or information documenting that the alternative monitoring requirement 

 would provide equivalent or better assurance of compliance with the relevant 

 emission standard. 

(4) The Administrator will notify the owner or operator of the approval or denial of the 

application within 90 calendar days after receipt of the original request, or within 60 

calendar days of the receipt of any supplementary information, whichever is later. 
 197 

 

The Administrator will not approve an alternative monitoring application unless it would 

provide equivalent or better assurance of compliance with the relevant emission standard. 

Before disapproving any alternate monitoring application, the Administrator will provide: 

(i) Notice of the information and findings upon which the intended disapproval is 

 based; and 

(ii) Notice of opportunity for the owner or operator to present additional supporting 

 information before final action is taken on the application. This notice will 

 specify how much additional time is allowed for the owner or operator to 

 provide additional supporting information. 

(5) The owner or operator is responsible for submitting any supporting information in a 

timely manner to enable the Administrator to consider the application prior to the 

performance test. Neither submittal of an application, nor the Administrator's failure to 

prove or disprove the application relieves the owner or operator of the responsibility to 

comply with any provision of this subpart. 

(6) The Administrator may decide at any time, on a case-by-case basis that additional or 

 alternative operating limits, or alternative approaches to establishing operating limits, 

 are necessary to demonstrate compliance with the emission standards of this subpart. 

 40 CFR 63.1350

 40 CFR 63.1355 

 Temporary, conditioned exemption from particulate matter and opacity standards

(a) Subject to the limitations of paragraphs (b) through (f) of this section, an owner or 

 operator conducting PM CEMS correlation tests (that is, correlation with manual stack 

 methods) is exempt from: 

 (1) Any particulate matter and opacity standards of part 60 or part 63 of this chapter that 

 are applicable to cement kilns and in-line kiln/raw mills. 

(2) Any permit or other emissions or operating parameter or other limitation on 

 workplace practices that are applicable to cement kilns and in-line kiln raw mills 

 to ensure compliance with any particulate matter and opacity standards of this part or 

 part 60 of this chapter. 

(b) The permittee must develop a PM CEMS correlation test plan. The plan must be submitted 

 to the Administrator for approval at least 90 days before the correlation test is scheduled to 

 be conducted. 

 The plan must include: 

 (1) The number of test conditions and the number of runs for each test condition; 

 (2) The target particulate matter emission level for each test condition; 

 (3) How the operation of the affected source will be modified to attain the desired 

 particulate matter emission rate; and 

(4) The anticipated normal particulate matter emission level. 

(c) The Administrator will review and approve or disapprove the correlation test plan in 

 accordance with Sec. 63.7(c)(3)(i) and (iii). If the Administrator fails to approve or 

 disapprove the correlation test plan within the time period specified in Sec. 63.7(c)(3)(iii), 

 the plan shall be considered approved, unless the Administrator has requested additional 
 200 

 

 information.

Appendix E. Fugitive Dust Plan
 241 

 

During the public comment period associated with the draft title V permit (EIQ # 92-2518, Facility # 

17-01-009), Holcim submitted comments regarding the Fugitive Dust Rule (567 IAC 23.3(2)(c)), as 

incorporated in Section II Plant Wide Conditions of the draft title V permit. Included with these 

comments was a proposed "Fugitive Dust Plan" which identified numerous potential sources of 

fugitive dust at the facility and specific measures or precautions to reduce or control such emissions, as 

applicable, to prevent the same from creating a nuisance and/or crossing the property boundaries of the 

Facility. As the proposed Fugitive Dust Plan is not classified as an "applicable requirement" it is not 

incorporated or otherwise made a part of this Title V permit. Notwithstanding, IDNR has evaluated 

the measures or precautions specified in the Plan for consistency and potential compliance with the 

Fugitive Dust Rule and has determined that such measures or precautions are considered, but may not 

constitute all, "reasonable precautions" given the nature and circumstances regarding the identified 

potential sources of fugitive dust. It should be noted that additional precautions may become necessary 

should the identified measures prove to be ineffective or due to adverse ambient conditions. Nothing 

herein excuses Holcim from compliance with the Fugitive Dust Rule.
