### D ESCRIPTION OF 

### F ACILITY 

### & P ROCESSES

### : Mitsubishi Cement’s Lucerne Valley plant is a Portland Cement manufacturing facility with a preheater Precalciner kiln. The hourly throughput is approxim ately 325-tons/hour feed. The preheater has four stages, and the Precalciner cons umes about 60% of the total fuel used in the kiln. The kiln currently fires coal and tires, with Biosolids (dewat ered sewage sludge) on an occasional basis, and natural gas as a back-up fuel. The raw mill is in-line with the kiln. This is an existing kiln, and there is no raw material dryer at this facility. Th e kiln does not waste cement kiln dust (CKD) at this time. Currently the kiln has the following raw material sources: Cushenbury mine for limestone and silica, the Silver Lake mine in Baker, CA, for iron from magnetite, and mines in Australia and Malaysia for alumina and bauxite. Other raw material sources are used as economics change.

Non-Applicable Requirements for Mitsubish i Cement Corporation Cushenbury Plant

Citation Description Explanation of Why Requirement is Not Applicable or How Requirement is Modified NSPS Subpart OOO New Source Performance Standards for Nonmetallic Mineral Processing This requirement is not applicab le to the primary and secondary limestone crushing system (B001009 and associated control devices), which was constructed prior to the NSPS Subpart OOO applicability cutoff date of August 31, 1983, and is not subject to NSPS Subpart OOO. 40CFR63 Subpart EEE Hazardous Waste Combustors All Standards in Subpart EEE NESHAP for Hazardous Waste Combustors These requirements do not apply to the MCC facility because biosolids and tires are not hazar dous waste as specified in 40 CFR 261, and MCC does not combust any other waste.

40CFR63 Subpart LLL 63.1350(c )(2) Procedure for daily visual opacity operations (modification to requirement) This requirement on the kiln (B001025) is modified as follows, due to clarification requested from Mojave Desert Air Quality Management District. Mitsubishi proposes to comply with (c)(2)(i) and (c)(2)(ii) by pe rforming daily visual opacity observations of the multi-stack baghouse in compliance with NSPS Subpart F, which states: "I n the event that visible emissions are observed for a number of emission sites from the control device with multiple stack, Method 9 observations shall be recorded from the emission site with the highest opacity" (40 CFR 60.63(c)).MDAQMD Federal Operating Permit MITSUBISHI CEMENT CORPOR ATION – Cushenbury Plant Permit Number: 11800001

Appendix B, Page 2 §60.672(a)(1) and §60.672(g) limit stack particulate matter (PM) emissions to 0.022 gr/dscf for any transfer point for belt conveyors or any other affect ed facility, including multiple storage bins with combined stack emissions (not including baghouses that control emissions only from an i ndividual enclosed storage bin) §60.672(a)(2) and §60.672(g) limit stack emi ssion opacity to 7% for any transf er point for belt conveyors or any other affected facility, including multiple storage bins with combined stack emissions §60.672(b) limit fugitive emission opacity to 10% for any transfer point on belt conveyors or any other affected facility §60.672(c) limit fugitive emission opacity to 15% from any crusher at which a capture system is not used. §60.672(d) truck dumping is exempt from above limits §60.672(f) limit stack emission opacity to 7% for any baghous e that controls emissions from only an individual enclosed storage bin §60.7(a)(4) Notify the Administrator of planned changes to the operation or equipment. §60.7(b) Keep records of the occurr ence and duration of any startup, s hutdown, or malfunction in operation §60.11(c ) The opacity standards set forth in this part sh all apply at all times excep t during periods of startup, shutdown, and malfunction. §60.11(d) At all times, including periods of startup, shut down and malfunction, owners and operators shall, to the extent practicable, maintain and operate any affected facility including asso ciated air pollution control equipment in a manner consistent with good air polluti on control practice for minimizing emissions. §60.8 and §60.675 perform initial compliance testing within 60 days after achieving the maximum production rate at which the affected facility will be operated, but not later than 180 days af ter initial startup and at such other times as may be required by the Administrator under Sec tion 114 of the Clean Air Ac t. Conduct test under such conditions as the Administrator shall specify to the plant operator based on representative pe rformance of the affected facility. Use EPA Method 5 or Method 17 to de termine compliance with the PM standard and use EPA Method 9 to determine compliance with opacity standard.

• The sample volume shall be at least 1.70 dscm (60 dscf). For Method 5, if the gas stream being sampled is at ambient temperature, the sampling probe and filter may be operated without heaters. If the gas stream is above ambient temperature, the sampling probe and filter may be operated at a temperature high enough, but no higher than 121°C (250°F), to prev ent water condensation on the filter.

• For transfer points on belt conveyors and any other a ffected facility, including multiple storage bins with combined stack emissions, the minimum total time of observations shall be 3 hours (30 6-minute averages). The duration may be reduced from 3 hours to 1 hour if there are no individual r eadings greater than the opacity limit and there are no more than 3 readings greater than the opacity limit for the 1-hour period.

• For baghouses that control emissions only form an i ndividual enclosed storage bin, the duration of the Method 9 observations shall be 1 hour (ten 6-minute averages).MDAQMD Federal Operating Permit MITSUBISHI CEMENT CORPOR ATION – Cushenbury Plant Permit Number: 11800001 Table B-2: NSPS Subpart A and Subpa rt OOO Requirements for Sand Plant

Appendix B, Page 3 • The minimum distance between the observer and the emission source shall be 4.57 meters (15 feet). The observer shall, when possible, select a position that minimizes interference from other fugitive emission sources (e.g., road dust). The requir ed observer position relative to th e sun (Method 9, Section 2.1) must be followed. For affected facilities using wet dust s uppression for particulate matter control, the spray sometimes generates a visible mist. The water mist mu st not be confused with particulate matter emissions and is not to be considered a visible emission. When a water mist of this nature is present, the observation of emissions is to be made at a point in the plume where the mist is no longer visible.

• A 30-day notice is required prior to th e initial performance test. If, af ter 30 days notice for an initially scheduled performance test, there is a delay in conducting any rescheduled performance test required in this section, the owner or operator of an affected facility shall submit a noti ce to the Administrator at least 7 days prior to any rescheduled performance test. §60.676(a) submit required information in case of equipment replacement. §60.676 (f) Submit a written report of all performance tests conducted to dem onstrate compliance with the PM and opacity standards. §60.676 (h) The requirement for notification of the anticipated date of initi al startup is waived. §60.676 (i) Notify the Administrator of th e actual date of initial startup.MDAQMD Federal Operating Permit MITSUBISHI CEMENT CORPOR ATION – Cushenbury Plant Permit Number: 11800001 Table B-3: NSPS Subpart A, Y, and OOO Applicability
