(§63.1206(b)(1)(ii)). Changes in design, operation or maintenance that may adversely affect compliance. If the permittee plans to change (as defined in §63.1205(b)(5)(iii)) the design, operation or maintenance practices of the source in a manner that may adversely affect compliance with an emission standard that is not monitored with a CEMS: (§63.1206(b)(5)(i))

• Restriction on Waste Burning – Except as provided by §63.1206(b)(5)(i)(C)(2), after the change and prior to submitting the notification of compliance, the permittee must not burn hazardous waste for more than a total of 720 hours (renewable at the discretion of the Admi nistrator) and only for purposes of pretesting or comprehensive performance testing. Pretesti ng is defined at §63.1207(h )(2)(i), and(ii)). (§63.1206(b)(5)(i)(C)(1))

• The permittee may petition the Administrator to obtain written approval to burn hazardous waste in the interim prior to submitting a Notifica tion of Compliance for purposes other than testing or pretesting. The permittee must specify operating requirements, including limits on operating parameters, that the permittee determines will ensure compliance with the emission standards of this subpart based on available information. The Administrator will review, modify as necessary, and approve if warranted the interim operating requirements. (§63.1206(b)(5)(i)(C)(2))

• Definition of Change – “Change means any change in design, operation, or mainte nance practices that were documented in the comprehensive performance test pl an, Notification of Complia nce, or startup, shutdown, and malfunction plan. (§63.1206(b)(5)(iii)) Compliance Dates:

(§63.1206(c)(3)(viii)(B)) Testing:

• The AWFCO system and associated alarms must be test ed at least weekly to ve rify operability, unless the permittee documents in the operating r ecord that weekly inspections will unduly restrict or upset operations and that less frequent inspection wi ll be adequate. At a minimum, the permittee must conduct operability testing at least monthly. The permittee must doc ument and record in the operating record AWFCO operability test procedures and results. (§63.1206(c)(3)(vii)) Monitoring:

• During periods of startup, shutdown, and malfunction, th e permittee shall operate and maintain such source (including associated air pollution c ontrol equipment) in accordance with the procedures specified in the startup, shutdown, and malfunction plan de veloped under §63.6(e)(3). (§63.6(e)(3)(ii))

• Corrective Measures – If, after any AWFCO, there is an exceedance of an emissi on standard or operating requirement, irrespective of whethe r the exceedance occurred while ha zardous waste remained in the combustion chamber (i.e., whether the hazardous waste residence time has transpired since the hazardous waste feed cutoff system was activated), the permitte e must investigate the cause of the AWFCO, take appropriate corrective measures to minimize future AWFCOs, and record the findings and corrective measure in the operating record. (§63.1206(c)(3)(v)) Record Keeping:

• The permittee shall keep a copy of the startup, shutdow n, malfunction plan on-site at all times. The plan shall be made available immediately for inspection to the Department of Natural Resources’ personnel upon request.

• When actions taken by the permittee during a startup, shutdown, or malfunction (i ncluding actions taken to correct a malfunction) are consistent with the procedures specified in the startup, shutdown and malfunction plan, the permittee shall keep records for that event that demonstrate th e procedures specified in the plan were followed. These records may take the form of a “ch ecklist,” or other effective form of record keeping, that confirms conformance with the startup, shutdown, a nd malfunction plan for that event. In addition the permittee shall keep records of these events as specifi ed in §63.10(b) (and elsewhere in this part), including records of the occurrence and duration of each startup, shutdown, or malfunction operation and each malfunction of the air pollution control equipment.

• The permittee must prepare and at all times operate according to an operation and maintenance plan that describes in detail procedures for operation, inspect ion, maintenance and corre ctive measures for all components of the combustor, including associated pol lution control equipment, that could affect emissions of regulated hazardous air pol lutants. (§63.1206(c)(7)(i)(A))

• The plan must prescribe how the permittee will operate and maintain the combustor in a manner consistent with good air pollution control practices for minimizing em issions at least to the levels achieved during the comprehensive performan ce test. (§63.1206(c)(7)(i)(B))

• The plan ensures compliance with the operation and maintenance requ irements of §63.6(e) and minimizes emissions of pollutants, automatic waste f eed cutoffs and malfunctions. (§63.1206(c)(7)(i)(C))

• Operation and maintenance requirements established pu rsuant to section 112 of the Act are enforceable independent of emissions limitations or other requi rements in relevant sta ndards. (§63.6(e)(1)(iii)) Monitoring:

• As specified in the operation and maintenance plan.

• At all times, including periods of startup, shutdown, and malfunction, permittee must operate and maintain any affected source, including associated air polluti on control equipment and monitoring equipment, in a manner consistent with safety and good air pollution c ontrol practices for minimizing emissions. During a period of startup, shutdown, or malfunction, this genera l duty to minimize emissions requires that the owner or operator reduce emissions from the affected source to the greatest extent which is consistent with safety and good air pollution control practices. The general duty to minimi ze emissions during a period of startup, shutdown, or malfunction does not require the permittee to achieve emissions levels that would be required by the applicable standards at othe r times if this is not consistent with safety and good air pollution practices, nor does it require the owner or operator to make nay further effo rts to reduce emissions if levels required by the applicable standard have been achi eved. Determination of whether such operation and maintenance procedures are being used will be based on information available to the Administrator which may include, but is not limited to, monitoring results , review of operation and maintenance procedures (including the startup, shutdown, and malfunction plan required in §63.6(e)(3)), review of operation and maintenance records, and inspec tion of the source. (§63.6(e)(1)(i))

• Malfunctions shall be corrected as s oon as practicable after their occurr ence in accordance with the startup, shutdown, and malfunction plan requir ed in §63.6(e)(3). To the extent that an unexpected event arises during a startup, shutdown, or malfunction, the perm ittee must comply by minimizing emissions during such a startup, shutdown, and malfunction event cons istent with safety a nd good air pollution control practices.

Construction Permit Revisions

The following revisions were made to c onstruction permits for this installation:

1) Construction Permit # 1086-004D On August 6, 2003, the installation was issued an amen dment to Special Condition # 7 of the Construction Permit # 1086-004C. The condition was revised to initia lly establish the maximum amounts of liquid waste and total hazardous waste that can be fed to the kiln based on data from a 1992 Boiler and Industrial Furnace (BIF) trial burn. The condition was also revised to allow altern ate feed limits validated by future compliance tests to replace existing limits. The pe rmit was amended to reflect transition from RCRA to MACT regulations. Unnecessary or no longer va lid conditions were eliminated. See EU0010-11

2) Construction Permit # 1086-004C Special Condition # 7 of this permit was am ended through the Construction Permit # 1086-004D

3) Construction Permit # 1086-004B The conditions of this permit were superceded by the conditions of Construction Permit # 1086-004C.

4) Construction Permit # 1086-004A The conditions of this permit were superceded by the conditions of Construction Permit # 1086-004C.

5) Construction Permit # 1086-004 The conditions of this permit were superceded by the conditions of Construction Permit # 1086-004C.

6) Construction Permit # 092002-022 This is a construction permit for a construction of a ne w kiln. The installation requested that the construction permit be listed, however, no provisions of the constructi on permit were incorporated into the Part 70 permit, because no construction was done yet.

7) Construction Permit Number 122001-014 The Special Condition was gap-filled as follows: “The permittee shall monitor th e amount of artificial soil replacement and maintain records on the PM 10 emissions on a rolling 12-month basis.” Was added to the Monitoring and Record Keeping of Permit Condition EU0470-01 through EU0510-01.

10 CSR 10-6.070, New Source Performance Regulations 40 CFR 60, Subpart F, Standards of Performance for Portland Cement Plants From 67 16619, Apr 5: “Section 63.1356(a) of the final rule is being revise d to clarify that in exempting affected sources subject to the portland cement NESHAP from duplicat ive requirements under 40 CFR part 60, subpart F, it was not our intention that these sour ces would then become affected sources under the requirements of 40 CFR part 60, s ubpart OOO (NSPS for Nonmetallic Mi neral Processing Plants). The requirements of 40 CFR part 60, s ubpart OOO may apply to certain s ources at a portland cement plant depending on whether or not 40 CFR part 60, subpart F, applies to that source. In particular, 40 CFR 60.670(b) states that if an emission source is subject to 40 CFR pa rt 60, subpart F, or follows in the plant process a source that is subject to subpart F, th en 40 CFR part 60, subpart OOO does not apply to that source. The purpose of Sec. 63.1356(a) of the final rule is to avoid having a s ource that is subject to certain requirements under this subpart also be subject to the same requirements unde r 40 CFR part 60, subparts F or OOO. The list of affected sources in the portland cement NESHAP is being am ended by combining into one paragraph the affected sources, ``bagging system'' and ``bulk loading or unloading system,'' maki ng the rule language consistent with the NSPS for portland cement plants (40 CFR part 60, s ubpart F).” All emission poi nts subject to 40CFR 63 Subpart LLL , section 63.1356(a) are exempted from 40 CFR 60 Subpart F, thus subpart F is not applicable.

10 CSR 10-6.070, New Source Performance Regulations 40 CFR 60, Subpart Y, Standards of Performance for Coal Preparation Plants Any facility affected that commences construction or modification after October, 24, 1974, is subject to the requirements of Subpart Y. All of the units used in coal preparation were constr ucted in 1966 thus Subpart Y does not apply. Subpart Y does not apply to transfer of coal from a coal mill to the kiln. From 67 16619, Apr 5: “Section 63.1356 of the final rule is being revised to clarify that the systems used to convey and transfer coal from the coal mill to the kiln at portland cement plants that ar e major sources of HAP are not subject to the NSPS for coal preparation plants (40 CFR part 60, subpart Y). The final portland cement NESHAP already cover conveying system transfer points associ ated with coal preparation plants at portland cement plants that are major sources. There is no need for these sources to be subject to duplicative requ irements, i.e., to also be covered by the NSPS for coal preparation plants. Furt her, these emission source s will be subject to more stringent opacity requirements (10 percent) under the NESHAP than under the NSPS for coal preparation plants (40 CFR part 60, subpart Y). Other coal conveying transfer points will conti nue to be subject to the NSPS for coal preparation plants.”

10 CSR 10-6.070, New Source Performance Regulations 40 CFR 60, Subpart OOO, Standards of Performance for Nonm etallic Mineral Processing Plants

The provisions of Subpart OOO are applicable to: each crusher, grinding mill, screening operation, bucket elevator, belt. The only emissions poi nts that Subpart OOO would be applicab le are listed in the table below. Only facilities that commenced construction, reconstr uction or modification after August 31, 1983 are subject to this rule. Since all the units in the table below were constructe d in 1966, Subpart OOO does not apply.

MACT Applicability 10 CSR 10-6.075, Maximum Achievable Control Technology Regulations 40 CFR Part 63, Subpart EEE, National Emission Standards for Hazardous Air Pollutants from Hazardous Waste Combustors The provisions of this subpart appl y to all hazardous waste combusto rs: hazardous waste incinerators, hazardous waste burning cement kilns and hazardous wa ste burning lightweight kilns. Since Continental Cement utilizes hazardous liquid and solids as a fuel source the part is fully applicable.

Continental Cement is a wet process kiln that utilizes Electrostatic Precipitator (ESP) as a control emission unit on its kiln exhaust. There is no mid-kiln sampling point. 40 CFR 63, Subpart EEE covers variety of sampling techniques and emission control op tions (i.e. activated carbon inject ion, baghouses, sampling at the kiln exhaust, etc.). Regulatory text cont ained in the permit was limited only to th e options applicable to Continental Cement’s facility.

The original version of the MACT was published in Federal Register, vol. 64, NO. 189 on September 30, 1999. Since then, there were several revisions to the MACT. A timeline of changes is presented below:

Original FR, vol. 64, No.189, September 30, 1999

Amended: FR, vol. 64, November 19, 1999 FR, vol. 65, No.132, June 10, 2000 FR, vol. 65, No. 218, November 09, 2000 FR, vol. 66, No. 93, May 14, 2001 FR, vol.66, No. 128, July 03, 2001 FR, vol. 66, No. 228, October 16, 2001 FR, vol. 66, No. 235, December 06, 2001 FR, vol. 67, No.30, February 13, 2002 FR vol. 67, No. 31, February 14, 2002 FR, vol 67, No. 244, December 19, 2002

On February 13, 2002 and February 14, 2002 EPA published interim rules in response to a court imposed remand of parts of the regulation. The rules are applicable until a new versi on of MACT is finalized (projected for 2005). This permit incorporates all of the ch anges to the MACT wording since September 30, 1999.

After 40 CFR Part 63, Subpart EEE is revi sed, the installati on will be subject to the revised standards. For an operating permit with an expiration date more than three (3) years away, the permit should be reopened to incorporate the new requirements. The mechanism for th is reopening, under the curren t Part 70 rules, would be a “reopening for cause”, upon rule modifications in the fe deral register. The changes to the permit will be made as expeditiously as possible, but no la ter than eighteen (18) months. As l ong as the installation is meeting the requirements of the revised rule, it is deemed to be in compliance. The Air Pollution Control Program will not view the installation as be ing in violation of the operating permit if the installation is complying with the revisions to a Federal or State Statut e or Regulation, as published in the Fe deral Register or Missouri Register.

Continental Cement applied and was granted a one (1) year extension on 40 CFR 63, Subpart EEE compliance on August 05, 2003. Based on the Compliance Extension letter Continental Cement Co. must comply with all provisions of 40 CFR 63, Subpart EEE no later than September 30, 2004.Continental Cement Company, L.L.C.. SB - 6 Installation ID Number: 173- 0001 Project Number: 173-0001-0001

Alternate Standard Provision: On May 19, 2003, Continental Cement petitioned the Air Po llution Control Program to “Define Alternate Mode of Operation When Hazardous Waste Residence Time has Expired - §63.1206(b)(1)(ii)”. Continental Cement proposed the following wording for the Alternate Standa rd Provision; “If the kiln is not burning hazardous waste, the permittee may comply with the alternat e mode of operation defined in the Comprehensive Performance Test Plan defined as follows: “Mode B, where the Operational Parameter Limits fo r: minimum combustion zone temperature, maximum production rate, maximum hazardous waste feed rate; and the Performance Standards for: SVMs, LVMs, HCl & CL, CO, and HG; will no longer apply to the kiln sy stem. For the Dioxin/Furan Standard, compliance with the Operational Parameter Limit for maximum Air Pollu tion Control Device (APCD) inlet temperature will be determined by calculated three-hour rolling aver age of recorded one-mi nute averages. All Subpart EEE standards and regulations not specifically menti oned in this paragraph will remain in effect.”

The petition was approved on December 16, 2003, thus the above language is being placed in the body of the permit under Alternate Sta ndard Provision heading.

Continental Cement will operate parts of the inst allation under either 40 FR 63 Subpart EEE or 40 FR 63 Subpart LLL. Continental Cement requested the flexib ility to switch between the EEE operation mode and an alternate operation mode as defined in the Initial Comprehensive Test Plan.

• The installation is a major source of HAPs, and therefore the clinker cooler, finish mills, conveying system transfer points, bagging systems and bulk loading / unloading systems are covered by the MACT. For the rotary kiln, the pr ovisions of 40 CFR Part 63, Subpart EEE, National Emission Standards for Hazardous Air Pollutants from Hazardous Waste Combustors, are to be followed.

According to 40 CFR Part 63, Subpart LLL – The first source affected are the ra w material storage just prior to the raw mill. If the emission units are not the raw material storage prior to the raw mill, the emission units are not covered by LLL:

“...the first affected source in the sequence of materials handling operations subject to this NESHAP is the raw material storage, which is just prior to the raw mill. The primary andContinental Cement Company, L.L.C.. SB - 7 Installation ID Number: 173- 0001 Project Number: 173-0001-0001

secondary crushers and any other equipment in the non-metallic mineral processing plant, which precede the raw material storage are not affected sources under this NESHAP. The first conveyor system transfer point subject to this NESHAP is the transfer point asso ciated with the conveyor transferring material from the raw material storage to the raw mill.”

Based on this definition, since the facility does not ut ilize a raw mill (wet slurry operation) the first emission units affected by 40 CFR Part 63 are the kiln dust processing units.

63 CFR Subpart LLL in §63.1350(a)(4)(v) states the followi ng: The requirement to conduct Method 22 visible emissions monitoring under this paragraph shall not appl y to any totally enclosed conveying system transfer point, regardless of the location of the transfer point. "Totally enclosed conveying system transfer point" shall mean a conveying system transfer point that is enclosed on all sides, top, and bottom. The enclosures for these transfer points shall be operated and maintained as tota l enclosures on a continuing basis in accordance with the facility operations and maintenance plan. The following points are totally enclosed:

If visible emissions from a building are monitored, the requirements of §63.1350(a)(4 )(i) through (iv) apply to the monitoring of the building, and you must also test vi sible emissions from each si de, roof and vent of the building for at least one -minute.

10 CSR 10-6.075, Maximum Achievable Control Technology Regulations 40 CFR Part 63, Subpart DD, National Emission Standards for Hazardous Air Pollutants from Off-Site Waste and Recovery Operations

The installation is not subject to 40 CFR Part 63, Subpart DD, due to the exemption stated in §63.683(c)(1). According to §63.683(c)(1): “An off-site material management unit is exempted from the requirements specified in §63.683(b), if the unit is also subject to another s ubpart under 40 CFR Part 61 or 40 CFR Part 63, and the owner or operator is controlling the HAP listed in Tabl e 1 of this subpart that are emitted from the unit in compliance with the provisions specified in the other applicable subpart.”

According to §63.680(b)(2)(vi) , the following materials are not off-site materials: “Waste that is generated by or transferred from units complying with all applicable requirements specified by 61.342(b) under 40 CFR 61 subpart FF – National Emi ssion Standards for Benzene Waste Operations for a facility at which the total annua l benzene quantity from the facility wa ste is equal to or greater than 10 megagrams per year.” The off-site waste is placed in hazardous waste storage tanks comply ing with 40 CFR Part 61, Subpart FF, therefore when the waste leaves these storage tanks or is "transferred from” these units complying with 40 CFR Part 61, Subpart FF, the waste is no longer off-site waste. According to the July 1, 1996 Preamble:Continental Cement Company, L.L.C.. SB - 9 Installation ID Number: 173- 0001 Project Number: 173-0001-0001

“Some NESHAP already regulate air emissions from the off-site management of certain wastes containing HAP. To avoid duplication of requirement s in these cases, the Off-Site Waste and Recovery Operations NESHAP does not apply to waste manage ment units that either receive waste from units complying with all applicable re gulations under the HON, or receive waste from units complying with all applicable requirements sp ecified by §61.342(b) under 40 CFR Part 61, Subpart FF – National Emission Standards for Benzene Waste Operations fo r a plant a which the to tal annual benzene quantity is greater than or equa l to ten (10) Mg/yr.” The cement kiln and the hazardous waste storage tanks are complyi ng with 40 CFR Part 61, Subpart FF, therefore the requirements for 40 CFR Part 63, Subpa rt DD were not included in the operating permit.

40 CFR Part 63, Subpart B, Requirements for Control Technology Determinations for Major Sources in Accordance with Clean Air Act Sections, Section 112(g) and 112(j) Continental Cement submitted Phase 1 Notification. It was determined that no provisions of 112(j) are applicable because Continental Ce ment Co. does not operate any e quipment covered by the regulation.

1 The particulate limit required by respective MACTs for EU0010 and EU0020 are far more stringent than the limit imposed by CSR 10-6.400, thus no emission limit for CSR 10-6.400 was calculated.

40 CFR 63.2 Definitions defines the Potential to Emit as: “... the maximum capacity of a stationary source to emit a pollutant under its physical a nd operational design. Any physical or operational limitation on the capacity of the stationary source to emit a pollutant, including air pollution contro l equipment and restrictions on hours of operation or on the type or amount of material combusted, stored or proce ssed, shall be treated as part of its design if the limitation or the e ffect it would have on emissions is federally enforceable. “

Potentials to emit presented in the above table were calculated based on sources Maximum Hourly Design Rate (MHDR). All emission factors used are for an uncontrolled total pa rticulate matter (PM).

Sample of calculations for EU0220 Finish Mill#1 Air Separator (EP: CM-10c)

Uncontrolled emission rate = MHDR * Emission Factor = 390 [ton/hr] * 0.028 [lbs/ton] = 10.92 lbs/hr

10 CSR10-6.400 limit for EU0220 is calculated using the following equation:

E = 55.0 * E 0.11 – 40 = 55.0 * (390) 0.11 – 40 = 66.02 lbs/hr

The uncontrolled emission rate at M HDR is 10.92 lbs/hr while the regu latory limit of 10CSR10-6.400 is 66.02 lbs/hr. Since the potential em issions is below the 10 CSR 6.400 Restriction of Emission of Particulate Matter from Industrial Processes limit the installation is required to mainta in calculations for th e process for emission unit EU0220. Using the same reasoning, we ask the instal lation to maintain on file calculation for emission units EU0030 through EU0100, EU0130 through EU0300, EU0320 through EU0390 and EU0420. (Please see the table above for numerical details)

For emission points EU0400, EU0410, EU430 and EU440 the uncontrolled emissions exceed the 10CSR10- 6.400 limit. However, the controlled emissions are far belo w the regulatory limit. In or der to assure that theContinental Cement Company, L.L.C.. SB - 12 Installation ID Number: 173- 0001 Project Number: 173-0001-0001

installation meet the regulatory requ irement we ask the permittee to mon itor the correspondi ng emission control equipment and adhere to record keeping and reporting requi rements. The rationale behi nd this request is that in case of the control equipment faili ng the installation may exceed the limit. Periodic monitoring of the equipment will assure its proper working conditions.

10CSR 10-6.400(3)(A)4 limits the concentr ation of particulate matter to 0.30 gr ains per standard cubic foot of exhaust gases. The limit is applicable to the points listed below. Data for the controlled potential were taken from previous table. As shown in the table below al l affected emission units have emissions less than 0.3 grains/standard cubic foot.

Sample of calculations for EU0220 Fini sh Mill#1 Air Separator (EP: CM-10c ). Calculations for other affected points are synonymous.

[0.07 lb/hr / 60 min/hr] * [7000 grains/lb] = 8.2 grains/min

[8.2 grains/min]/[1200stdft 3 /min] = 0.007 grains/stdft 3

Emission Units Without Limitation The sources listed as units without limitati on in this permit fall into two categories.

Fugitive sources, which do not emit regulated pollutants from a discrete stack or vent. These sources emit particulate matter and volatile organic compounds directly into the ambient air. These sources do not have any type of capture/control devices and are not covered or required to contro l their emissions based on any past or current regulations. These sources are not subject to a ny specific rule except the in stallation wide requirement of 10 CSR 10-6.170 and must comply with this requiremen t. Storage piles and haul roads are included in that category.

The following storage piles and haul roads were placed in the Emission Units Without Limitations category:

1. The provisions of Subpart OOO are applicable to: each crusher, grinding mill, screening operation, bucket elevator, belt. The only emissions points that Subpart OOO would be applicable to are listed in the table below.

Only facilities that commenced construction, rec onstruction or modification after August 31, 1983 are subject to this rule. Since all the units in the table below were constructed in 1966, Subpart OOO does not apply. Since these units have no emission controls 10 CSR 10-6.220, Restriction of Emission of Visible Air Contaminants does not apply either. Thus, the only appl icable rule is the installation wide requirement of 10 CSR 10-6.170.Continental Cement Company, L.L.C.. SB - 15 Installation ID Number: 173- 0001 Project Number: 173-0001-0001
