2 F ACILITY D ESCRIPTION The existing facility is an integrated facility that includes a Portland cement manufacturing plant, a power plant and a coal yard. The power boiler is a coal fire d unit that is allowed to generate a net delivered 150 MW. The cement kiln I, in-line kiln/raw mill and c linker cooler I share a common baghouse fabric filter system (for particulate matter emissions control) and stack with the power plant. Dry limestone injection is used to control SO 2 emissions from the power boiler, which is then collected in the common baghouse fabric filter system. Waste heat from the kiln is used to provide heat to the raw mill and the kiln preheater, which is used to drive off moisture from th e materials used for making clinker. All of the materials handling activities are controlled by fabric filter baghouse control systems, except for the Clinker Receiving/Handling System and the coal ya rd activities. For the Clinker Receiving/Handling System, the fugitive particulate matter emissions gene rated from the transfer of clinker from the receiving hopper to the belt conveyor are controlled using a J ohnson-Marsh Dust Suppressant system, which uses a non-ionic wetting agent to enhance the wettability of the clinker. Water sprays or chemical wetting agents and stabilizers are used at the coal receiving area, the coal storage area, and the coal transfer system to control fugitive particulate matter emis sions and minimize visible emission. All fly ash handling systems (including transfer and silo storag e) are totally enclosed and vented (including pneumatic system exhaust) through fabric filters.

This project is for a new cement manufacturing line (l ine 2) at the existing facility. New emissions units for the project will include a raw mill system, a dr y process preheater/precalciner kiln system, clinker handling system, finish grinding operations, two cemen t loadout silos, and coal handling and grinding operations. Line 2 will have a capacity of 206.3 tons per hour of material fed (dry basis) to the preheater, 125 tons per hour of clinker production, and 138 t ons per hour of Portland cement production. The annual rates for the proposed system are not based on the maximum allowable rates for feed material and clinker production. This project is subject to Prev ention of Significant Deterioration (PSD) Review and a Best Available Control Technology (BACT) determination for NO x , PM, PM 10 , SO 2 , CO, and VOC. The plant will be installing Selective Non-cataly tic Reduction (SNCR) technology to control NO x emissions from the new line. NOx emissions li mit from the kiln will be 1.95 lbs of NOx per ton of clinker (243.8 lb/hour). Emissions limits for PM, PM 10 , SO 2 , CO, and VOC are 0.23 pounds of PM per ton of clinker (28.8 lb/hr), 0.20 pounds of PM 10 per ton of clinker (25.0 lb/hr), 0.23 pounds of SO 2 per ton of clinker (28.8 lb/hr), 3.60 pounds of CO per ton of clinker ( 450 lb/hr), and 0.12 pounds of VOC per ton of clinker (15 lb/hr), respectively. Mercury emissions will be limited to 122 lbs per year from the new line, and visible emissions from the line will be limited to 10% opacity. Daily and annual rates are 1,686,300 tons per year (4,620 tons/day, 24-hour average) of material fed to the preheater (dry basis), 1,022,000 tons per year (2,800 tons/day, 24-hour average) of clinke r production, and 1,301,138 tons per year (5,760 tons/day) of cement production. Fuels allowed to be used in the pyroprocessing system are natural gas, distillate fuel oil, on specification used oil, coal, pe troleum coke, propane, flyash, and tire derived fuels. The plant will also include a coal processing operatio n that will crush coal and petroleum coke and will have an annual processing capacity of 131,400 tons of coal and petrol eum coke. The new raw material and handling storage shall not process more than 225 tons per hour of raw material (1,971,000 tons per year) in any consecutive 12-month period.AIR CONSTRUCTION PERMIT 0530021-009-AC, PSD-FL-351

R EGULATORY C LASSIFICATION

This facility is classified as a Major or Title V S ource of air pollution because emissions of at least one regulated air pollutant, such as particulate matter (PM/PM 10 ), sulfur dioxide (SO 2 ), nitrogen oxides (NOx), carbon monoxide (CO), or volatile organic co mpounds (VOC) exceeds 100 tons per year (TPY).

This facility is within an industry included in the list of the 28 Major Facility Categories per Table 62- 212.400-1, F.A.C. Because emissions are greater than 100 TPY for at least one criteria pollutant, the facility is also a Major Facility with respect to Ru le 62-212.400, Prevention of Significant Deterioration (PSD). The proposed project is subject to the provisions of Rule 62-212.400, F.A.C., Prevention of Significant Deterioration (PSD), because it is a modification to an existing facility. The Department has determined this facility is a ma jor source of hazardous air pollutants (HAPs) and is subject to 40 CFR 63, Subpart LLL, National Emissions Standard for Portland Cement Manufacturing. The emissions units included in this project are subject to regulation under the New Source Performance Standards, 40 CFR 60 Subpart A, General Provisions , Subpart F, Standards of Performance for Portland Cement Plants, and Subpart Y Standards of Perform ance for Coal Preparation Plants. Some of these emissions units are also subject to 40 CFR 63 Subp art LLL, National Emission Standards for Hazardous Air Pollutants from the Portland Cement Manufacturing Industry (40 CFR 63.1340 – 63.1359) and 40AIR CONSTRUCTION PERMIT 0530021-009-AC, PSD-FL-351

Excess emissions resulting from startup, shutdown or malfunction of any emissions unit shall be permitted providing (1) best operational practices to minimize emissions are adhered to and (2) the duration of excess emissions shall be minimized but in no case exceed two hours in any 24 hour period unless specifically authorized by the Depart ment for longer duration. Excess emissions which are caused entirely or in part by poor maintenance, poor operation, or any other equipment or process failure which may reasonably be prevented durin g start-up, shutdown, or malfunction shall be prohibited. [Rule 62-210.700, F.A.C.]

17. Required Number of Test Runs : For mass emission limitations, a compliance test shall consist of three complete and separate determinations of the total air pollutant emission rate through the test section of the stack or duct and three complete and separate determinations of any applicable process variables corresponding to the three distinct time periods during which the stack emission rate was measured; provided, however, that three complete an d separate determinations shall not be required if the process variables are not subject to variation during a compliance test, or if three determinations are not necessary in order to calculate the unit's emis sion rate.

18. Frequency of Compliance Tests . The following provisions apply only to those emissions units that are subject to an emissions limiting standard for which compliance testing is required. (a) General Compliance Testing. 3. The owner or operator of an emissions unit that is subject to any emission limiting standard shall conduct a compliance test that demonstrates co mpliance with the applicable emission limiting standard prior to obtaining a renewed operation perm it. Emissions units that are required to conduct an annual compliance test may submit the most recent annual compliance test to satisfy the requirements of this provision. In rene wing an air operation permit pursuant to Rule 62-210.300(2)(a)3.b., c., or d., F.A.C., the Depart ment shall not require submission of emission compliance test results for any emissions un it that, during the year prior to renewal: a.
