This verbal re port 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 stan dard if the startup, shutdown or cleaning is accomplished expeditiously and in a manner consiste nt with good practice for minimizing emissions. Cleaning of control equipment which does not require the shutdown of the proc ess 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 contro l 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 emissi on shall be repaired in an expeditious manner or the process generating the emissions shall be sh utdown within a reasonable period of time. An expeditious manner is the time necessary to determin e 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. InTitle 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 m eet consumer demand with the affected unit out of service, unless, the director sh all, upon investigation, reasonably determine that continued operation constitutes an unjustifiable environm ental hazard and issue an order that such operation is not in the public interest and requ ire 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 st artup, shutdown, or cleaning) sha ll 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 fo r an incident of excess emission during startup, shutdown or cleaning does not reli eve the owner or opera tor of a source with continuous monitoring equipment of the obligation of submitting reports re quired 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 c ontinues 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 opacit y. 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 repor t 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 incl ude as a minimum the following: i. The identity of the equipment or source operati on 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 preven t 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 pur poses of this permit, an “emergency ” means any situation arising from sudden and reasonabl y unforeseeable events beyond the control of the source, including acts of God, which requires immedi ate corrective action to restore normal operation, and that causes the source to ex ceed 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 desi gned equipment, lack of preventive maintenance, careless or improper operation or opera tor error. An emergency constitute s 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 rele vant 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 standard s 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 limita tions were exceeded due to the emergency. This notice must contain a description of the emergenc y, 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 re sult in a hazardous release or exce ss 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 a nd 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) (s tandards of performance of new stationary sources) or section 111 of the Act; or 567-subrule 2 3.1(3) (emissions standards for hazardous air pollutants), 567-subrule 23.1(4) (emissi on standards for hazardous air pollutants for source categories) or section 112 of the Act. This notification shall be su bmitted in writing to the department pursuant to the notification require ments in 40 CFR Section 60.7, 40 CFR Section 61.07, and/or 40 CFR Section 63.9. 567 IAC 23.1(2), 567 IAC 23.1(3), 567 IAC 23.1(4) G17.

For such a change, the permitted source provides to the department and the administrator by certified mail, at least 30 days in advance of the propos ed change, a written notification, including the following, which must be attached to the permit by the source, the department and the administrator: i. A brief description of the change within the permitted facility, ii. The date on which the change will occur, iii. Any change in emission as a result of that change, iv. The pollutants emitted subject to the emissions trade v. If the emissions trading provisions of the state implementation plan are invoked, then Title V permit requirements with which the source shall comply; a description of how the emissions increases and decreases will comply with the terms and conditions of the Title V permit. vi . A description of the tradi ng of emissions increases and decr eases for the purpose of complying with a federally enforceable emissions cap as speci fied in and in compliance with the Title V permit;Title V Permit 11/10/005 90 

### and vii. Any permit term or condition no longe r applicable as a result of the change. 567 IAC 22.110(1) 2. Such changes do not include ch anges that would violate applicab le requirements or contravene federally enforceable permit terms and conditions that are monitoring (including test methods), record keeping, reporting, or complian ce 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 implementatio n plan authorizing the emissions trade. 567 IAC 22.110(4) 5. No permit revision shall be required, under any a pproved economic incentives, marketable permits, emissions trading and other similar programs or pro cesses, 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 re vision 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 administ rative change at the source; iii. Require more frequent monitoring or reporting by the permittee; or iv. Allow for a change in ownership or operational control of a source where the director determines that no other change in the permit is necessary, provided that a writte n agreement containing a specific date for transfer of permit responsibility, coverage and liability between the current and new permittee has been submitted to the director. b. The permittee may implement the changes addressed in the request for an administrative amendment immediately upon submittal of the request. The request shall be submitted to the director. c. Administrative amendments to portions of pe rmits containing provisions pursuant to Title IV of the Act shall be governed by regulations prom ulgated by the administrator under Title IV of the Act. 2. Minor Permit Modification. a. Minor permit modification procedures may be us ed only for those permit m odifications that do any of the following: i. Do not violate any applicable requirements ii. Do not involve significant ch anges to existing monitoring, reporti ng or recordkeeping requirements in the Title V permit. iii. Do not require or change a case by case determ ination of an emission limitation or other standard, or increment analysis. iv. Do not seek to establish or change a permit term or condition for whic h there is no corresponding underlying applicable requirement a nd 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 so urce 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 

### v. Are not modifications under any pr ovision of Title I of the Act; and vi. Are not required to be pro cessed as significant modification. b.

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 a nd 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/m 3 

### ). DNR monitored six exceedences of this standard at a prev ious DNR monitoring site located at the intersection of 17 th 

### 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/m 3 

### , respectively. On February 22, 1994, the same monitoring site recorded a 24-hour av erage PM-10 concentration of 160 ug/m 3 

### . On December 18, 1995, and March 5, 1996, the sa me monitoring site recorded 24-hour average PM-10 concentra tions of 239 and 286 ug/m 3 

### , respectively.

2. Holcim is a cement manufacturer lo cated at 1840 North Federal Avenue in Mason City, Iowa, which is north of th e previous PM-10 monitoring site at 17 th 

### and Quincy. Air dispersion modeling of this Ho lcim facility has b een conducted. This modeling predicts that Holcim is a cont ributor to the PM-10 levels monitored.

3. Holcim is not the sole contributor of PM-10 levels in Mason City and other contributors also ar e 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 Ad ministrative 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 pr event 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 defi ned by Iowa Code section 455B.131(2), and “stationary sources” and “fug itive 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 Pr imary and Secondary Ambient Air Quality Standards (NAAQS) located at 40 C.F.R. Pa rt 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 quali ty standard for PM-10 is 150 ug/m 3 

### , 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/m 3 

### , 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/m 3 

### , 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 th e 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 st ationary source shall obtain a permit to install or alter equipment or control equipment unless otherw ise exempt. Any modi fications 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 m eet the requirements of a construction permit exemption contained in the pr ovisions 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 ta ke reasonable precautions to prevent the

### IOWA DEPARTMENT OF NATURAL RESOURCES Administrative Consent Order ISSUED TO: Holcim (US), Inc.

### 7. Control of Fugitive Emissions from Unpaved Haul Roads: (i). Fugitive emissions from the M3 li mestone haul road shall be controlled by applying a chemical dust suppressant. A c ontrol efficiency of 95 percent shall be maintained on the entire length of both segm ents 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 chemi cal dust suppressant shall be a pplied no less frequently than once every other week to main tain the established ground inve ntory. This equates to 0.05 gallons of chemical dust suppressant per s quare yard, or a manuf acturer’s equivalent application to achieve the 95 percent control efficienc y. Different manufacturer’s materials have different applications to ach ieve 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 suppr essant. Applications of the selected chemical dust suppressant and the record keeping requirements de scribed below shall begin within 30 days of the e ffective date of this Admini strative Consent Order. A control efficiency of 95 percent shall be ma intained 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 ch emical 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 a pplication to achieve the 95 percent control efficiency. Different manufacturer’s materi als 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 s uppressant can not be applied because the ambient air temperature (as measured at the facility during daylight operating hours) will be less than 35 0 

### F (1.7 0 

### C) or conditions due to weat her, in combination with the application of the chemical dust suppressant , could create hazardous driving conditions, then the chemical dust suppressant applicati on shall be postponed and applied as soon after the scheduled application date as th e 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 dus t suppressant is not applied as planned, then the records should so indicate and provide an explanation.

### AFFECTED SOURCES – Defi nitions and nomenclature

Overview of the portland cement production process

The production of cement is a five-step proc ess: 1) raw meal preparation system, 2) clinker manufacture system, 3) clinke r cooler system, 4) cement manufacture system, 5) packing, dispatch, distribu tion and blending. Mining or quarrying obtains the majority of raw material s used in cement production. The raw materials are ground and proportioned so th at the mixture or “kiln feed” has the desired fineness and chemical compos ition 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 cemen t manufacturing process is divided into functional locations. Each main ta sk of the plant ha s 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 di git is the main cost center; the second number is the group number; and the thir d 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.Approved: 08/16/05 6 O&M Plan Revision Date: 08/16/2005 Revision No. 0 Approved By: Jason Morin Holcim Mason City Plant

### 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 (d iverter, 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 feed er would be considered an affected source 6. Rotary valves that are used to meter ma terial are considered feeders and are treated identical to weigh and volumetric feeders 7. Bag filters are identified as pollu tion control devices by their HAC#. 8. Valves (rotary, flap, slide gat es) 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 filt er 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 equi pment, 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 identi fied 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 conv eyors are identified by the feeder or conveyor HAC# unless there is a transfer chute betwe en 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 dive rter gate creates two affected sources. These sources are identified by the chute immediatel y preceding the destination of the transfer. 15. A material storage bin is identifi ed as an affected source by its HAC#. 16. Transfer points to waste, storage piles or trans port 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 lar ge quantities of in-process materials, i.e., ground coal and raw mix, are considered to be encl osed conveying systems. For identification purposes, the conveyor transfer points in t hese systems are identifi ed by the duct HAC#.Approved: 08/16/05 8 O&M Plan Revision Date: 08/16/2005 Revision No. 0 Approved By: Jason Morin Holcim Mason City Plant 

### Conveying System Transfer Poin ts – 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 requiremen ts according to their placement and control. As a result, transfer points ar e 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 with in a building, the building itself can be tested (40 CFR 63.1350(a)(4)(vi)).

Group 3: Partially enclosed or totally en closed CSTPs with an APCD – These CSTPs are ducted to an APCD. Conseque ntly, a monthly Met hod 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 th at are dust free, such as tires or coal, are not considered in the listing of CSTPs.Approved: 08/16/05 9 O&M Plan Revision Date: 08/16/2005 Revision No. 0 Approved By: Jason Morin Holcim Mason City Plant 

### Maintenance System

Following is an overview of the plant preventat ive 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 failu res of general types of proc ess equipment at the plant.

Historical records may include information such as the performance of the equipment. Vendor manuals for equipment may also provide sugg ested preventative ma intenance tasks and associated frequencies. The FMEA system lists t he various possible ways the equipment might fail (referred to as functional failures), identifie s 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 ai d to prioritize PM tasks and to suggest options for repairs; however, the PM interval reco mmendations contained in the FMEA are only guidelines.

Preventive maintenance and inspections at t he facility are often managed using a plant data management system that generates preventive ma intenance 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 gener ated when non-routine preventive maintenance issues are identified during per iodic 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.Approved: 08/16/05 10 O&M Plan Revision Date: 08/16/2005 Revision No. 0 Approved By: Jason Morin Holcim Mason City Plant 

### 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 Syst em (Raw Mills and Dryer)

PROCESS DESCRIPTION

The raw meal preparation system co mbines the drying, blending and grinding of the raw materi als to form the kiln feed. Raw material is taken from the on-site quarry and transported to the mill feed syst em. Corrective materials used to obtain quality standards are received by truck or rail and sometimes dried depending on the mois ture content and transported to the mill feed system. With in the mill feed system, the raw materials are heated and dried, as they are being gr ound in the ball mill. After the ball mill, the raw meal product is homogeni zed 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 indi vidually. At specified intervals, a compartment of bags is cleaned by forci ng 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 auto matically and sequentially cleaned. To facilitate this action, a pulse valve deliv ers a burst of compressed air through the bags in reverse direction to remove ma terial from the bags. The collected material is returned to the process, sold as by-product, or removed for disposal.

The electro static precipita tor (ESP) removes the dust in the air stream. The air stream passes through the ESP where the pa rticles become electrically charged. These particles collect on negatively- charged hanging plates. Accumulated particulate is removed by rapping the coll ecting 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, st orage bins, and baghouse PMCDs.

### MAINTENANCE PROCEDURES FOR THE RAW MEAL PREPARATION SYSTEM

Preventive maintenance (PM) at the facility is conducted in accordance with Historical maintenance records, v endor manuals for specific pieces of equipment, and/or the result s of a Failure Mode Effects Analysis (FMEA) which serves as a guideline for prioritizing maintenance and preventing failures of general types of proce ss 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 occurr ing, 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 pr ocess adjustment is completed 5) If the equipment was stopped in order to comp lete the repair, it is brought back into operation. The operation is observed to ensur e 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 completedApproved: 08/16/05 22 O&M Plan Revision Date: 08/16/2005 Revision No. 0 Approved By: Jason Morin Holcim Mason City Plant 

### CLINKER MANUFACTURE System (KILN)

PROCESS DESCRIPTION

Kilns are rotating steel tubes lined with re fractory 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 tr ansferred 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 co mplex chemical reactions of clinker production. The dust generated in the clin ker 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 pre ssurized 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 clinke r manufacture system range from 4XXXXX to LXX-XXX. This includes the followi ng 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.

### 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 guide lines. 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 manu facture system operation, key process parameters are monitored and recorded using data loggers. The detailed procedures for continuous monitoring sy stem operation associated with the clinker manufacture system are containe d in the Continuous Monitoring System Standard Operating Proce dures (CMS SOP) CMSP-001.

MONITORING REQUIREMENTS FO R THE CLINKER MANUFACTURE SYSTEM

Table 4.2-2 contains the ope rating and monitoring requirements for the various affected source types included in the c linker manufacture system. A continuous monitoring system requirement flow ch art for COMS and Thermocouples is provided as Figure 4-4. The monitoring re quirement 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 manuf acturing system is malfunctioning or data is not being recorded for an ex tended period of time while the system continues to operate, in addition to in itiating corrective action to repair the monitor, alternative monitoring will be ini tiated in order to demonstrate that the source remained in compliance during the peri od 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 emissi ons test will be performed each day that COMs data is invalid or unava ilable 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 malf unctioning or data is not being recorded for more than 24 hours, alternate indi cators of temperatur e control at the particulate matter control device will be monitored and documented in order to demonstrate compliance.Approved: 08/16/05 29 O&M Plan Revision Date: 08/16/2005 Revision No. 0 Approved By: Jason Morin Holcim Mason City Plant

### CLINKER COOLER SYSTEM

PROCESS DESCRIPTION

The function of the clinke r cooler system is to cool the c linker to make it possible to handle with conventional conveying equipment. The c linker 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 re mains as a deposit on the bags’ outside surface. At specified intervals, as n eeded, a cleaning cycle is initiated in which the bags are automatically and seque ntially cleaned. To f acilitate 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: th e 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.Approved: 06/13/2002 34 O&M Plan Revision Date: 06/13/2002 Revision No. 0 Approved By: Paul Stewart Holcim Mason City Plant

### 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 Pr ocedures SOP-KL2 and SOP-KL3. During the clinker cooler operation, opacity is measured with a continuous opaci ty monitor (COM). Detailed procedures for continuous monitoring system operation associat ed with the clinker cooler are contained in the Continuous Monitoring System Standard Operating Procedure (CMS SOP) CMSP-001.

MONITORING REQUIREMENTS FO R THE CLINKER COOLER SYSTEM

Table 4.3-2 contains the operating and monitoring requirements for the various affected source types included in the clinker c ooler system. A continuous mon itoring 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 structur e, are provided as Figures 4-2 and 4-3, respectively.Approved: 06/13/2002 42 O&M Plan Revision Date: 06/13/2002 Revision No. 0 Approved By: Paul Stewart Holcim Mason City Plant

### 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 be ing recorded for an ex tended period of time while the system continues to operate, in additio n 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 fac ility 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 (FME A) which serves as a guideline for prioritizing maintenance and preventing failures of general ty pes of process equipment at the plant. Refer to Section 3.0 for details.

CORRECTIVE ACTION PROGRAM

A corrective action program has been develope d and implemented to diagnose, repair, and document equipment malfunctions. Corrective acti on will be initiated as soon as practicable after a malfunction is identified and will be co mpleted within a reasonable time after its initiation. The corrective action program includes perfor ming 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 pr ocess adjustment is completed 5) If the equipment was stopped in order to complete t he repair, it is brought back into operation. The operation is observed to ensure that it st arts and continues to operate as expected. 6) The work order/maintenance notification/malfunc tion 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 completedApproved: 06/13/2002 44 O&M Plan Revision Date: 06/13/2002 Revision No. 0 Approved By: Paul Stewart Holcim Mason City Plant 

### 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 de signed with internal frame struct ures called cages. The dust does not penetrate the bags and collects on the bags’ outsi de surface and forms a dustcake. At specified intervals, the dustcake is periodi cally 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 mate rial 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 a nd is directed to the filter bags. The dust is collected on the inside of the vertically ha nging bags, while the clean air exits through the outside of the bag. During the cleaning cycl e, 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 collap se, which causes the dustcake to break and fall into the hopper. The collected material is returned to the pr ocess, 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 sour ce types: the finish mills, conveying system transfer points, storage bi ns, and baghouse PMCDs.

Preventive maintenance (PM) at the facility is conducted in accordance with historical maintenance records, vendor manuals for s pecific pieces of equipment, and/or the results of a Failure Mode Effects Analysis (FMEA) which serves as a guideline for prioritizing maintenance and pr eventing 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 devel oped 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 perform ing 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 pr ocess adjustment is completed 5) If the equipment was stopped in order to complete t he repair, it is brought back into operation. The operation is observed to ensure that it st arts and continues to operate as expected. 6) The work order/maintenance notification/malfunc tion 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 completedApproved: 06/13/2002 62 O&M Plan Revision Date: 06/13/2002 Revision No. 0 Approved By: Paul Stewart Holcim Mason City Plant 

### 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 stor age 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, dispat ch, and distribution system range from 61XXXX to 6EX-XXX. This includes the following affected source types: conveying system transfer points, storage bi ns, and baghouse PMCDs.

Table 4.5-1 provides a list of the affected sources in the system.Approved: 06/13/2002 63 O&M Plan Revision Date: 06/13/2002 Revision No. 0 Approved By: Paul Stewart Holcim Mason City Plant

The complia nce 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 applica tion to the Administrator for approval of alternate monitoring requirements to demonstr ate compliance with the emission standards of this subpart, except for emission standards for TH C, subject to the provi sions 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 docum ents, using data or information, that the longer averaging period will ensure that emissi ons do not exceed levels achieved during the performance test over any in crement of time equivalent to the time required to conduct three runs of the performance test. (2) If the application to use an alternate monitoring requireme nt is approved, the owner or operator must continue to use the orig inal monitoring requirement until approval is received to use another monitoring requirement. (3) The owner or operator shall submit the a pplication for approva l 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 requ est, such as the technical or economic infeasibility, or the impracti cality of using the required approach; (ii) A description of the proposed alternativ e 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 comp liance with the relevant emission standard. (4) The Administrator will notify the owner or ope rator of the approval or denial of the application within 90 calendar da ys after receipt of the orig inal request, or within 60 calendar days of the receipt of any supplem entary information, whichever is later.197 

### The Administrator will not approve an altern ative monitoring application unless it would provide equivalent or better assurance of co mpliance with the relevant emission standard. Before disapproving any alternate monitoring application, the Admini strator 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 ope rator to present a dditional supporting information before final action is take n 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 fo r 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 a pplication, nor the Administrator's failure to prove or disprove the applica tion relieves the owner or opera tor 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 w ith the emission standards of this subpart. 40 CFR 63.1350

# Appendix E. Fugitive Dust Plan241 

### During the public comment period associated with the draft title V permit (E IQ # 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 perm it. Included with these comments was a proposed "Fugitive Dust Plan" wh ich 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 cr ossing the property boundaries of the Facility. As the proposed Fugitive Dust Plan is not classified as an "applicab le 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 m easures or precautions are considered, but may not constitute all, "reasonable precautions" given the na ture and circumstances regarding the identified potential sources of fugitive dust. It should be no ted that additional precautions may become necessary should the identified measures prove to be ineffec tive or due to adverse ambient conditions. Nothing herein excuses Holcim from compliance with the Fugitive Dust Rule.242243
