FACILITY DESCRIPTION 

The proposed facility will be a dry process greenfield portland cement plant incorporating a dry process kiln with 

a preheater and calciner (PH/C). The nominal capacity is 1,715,500 tons per year of clinker. Major equipment 

associated with the main components of the plant will include the following: 

• A raw materials storage building (MSB) and a limestone storage building; 

• A primary crusher at the quarry and belt conveyors to MSB; 

• Raw material piles stored inside of the storage buildings. The piles will include limestone, alumina sources 

(e.g. bauxite and coal ash), iron sources (e.g. mill scale, slag, and iron ore), silica sources (e.g. sand, and 

clay), and additives (e.g. feldspar, and gypsum); 

• Materials handling equipment including reclaimers, stackers, belt conveyors, covered conveyors from the 

MSB and limestone storage building to the raw mill, control system/analyzer, etc.; 

• An in-line raw mill that simultaneously dries raw materials using the exhaust gas from the kiln, PH/C, and 

clinker cooler; 

• A preheater with staged combustion calciner and selective non-catalytic reduction (SNCR) system; 

• An air heater for use when additional drying capacity is required; 

• A nominal 12,000 ton per day blending silo; 

• An indirect-firing system with a Low NOX main kiln burner capable of burning coal, petroleum coke, fuel oil, 

and natural gas; 

• A whole tire feeder and/or tire gasification system. 

• A clinker cooler with cooling air fans, and hot air ducting to the kiln, PH/C, and raw mill; 

• Clinker storage and grinding including two finish mills with air separators, clinker silos with metering 

devices, limestone and gypsum bins and associated conveyors; 

• Cement transfer and storage silos, truck loadouts and packhouse; and 

• A nominal 28.4 TPH coal and/or petroleum coke grinding system with associated mill, storage facility, 

associated conveyors, and equipped with a fabric filter baghouse. 

REGULATORY CLASSIFICATION 

Title III: The cement plant will be a major source of hazardous air pollutants (HAP). 

Title V: The cement plant will be a Title V major source in accordance with Chapter 62-213, F.A.C. because the 

potential emissions of at least one regulated pollutant exceed 100 tons per year. Regulated pollutants include 

pollutants such as carbon monoxide (CO), nitrogen oxides (NOX), particulate matter (PM/PM10), sulfur dioxide 

(SO2), and volatile organic compounds (VOC). 

PSD: The facility is located in an area that is designated as “attainment”, “maintenance”, or “unclassifiable” for 

each pollutant subject to a National Ambient Air Quality Standard. It is classified as a “portland cement plant”, 

which is one of the 28 Prevention of Significant Deterioration (PSD) Major Facility Categories with the lower 

PSD applicability threshold of 100 tons per year. Potential emissions of at least one regulated pollutant exceed 

100 tons per year, therefore the facility is classified as a major source of air pollution with respect to Rule 62-

212.400 F.A.C., Prevention of Significant Deterioration of Air Quality. 

NSPS: Portions of the cement plant are subject to the following New Source Performance Standards (NSPS) in 

40 CFR 60: Subpart A (General Provisions); Subpart Y (Coal Preparation Plants); and Subpart OOO (Non 

Metallic Mineral Processing). Any affected source subject to the provisions of 40 CFR 63, Subpart LLL

cooler and air heater. 

APPLICABLE STANDARDS AND REGULATIONS

1. BACT Determinations: A determination of the Best Available Control Technology (BACT) was made for 

carbon monoxide (CO), nitrogen oxides (NOX), sulfur dioxide (SO2), volatile organic compounds (VOC), 

and particulate matter (PM/PM10). 

2. NESHAP Requirements: This unit is subject to 40 CFR 63, Subpart A (Identification of General 

Provisions) and 40 CFR 63, Subpart LLL (National Emissions Standard for Hazardous Air Pollutants from 

the Portland Cement Manufacturing Industry). The Department determines that the BACT emissions 

performance requirements are as stringent as or more stringent than the limits imposed by the applicable 

NESHAP provisions for particulate matter. Some separate reporting and monitoring may be required by the 

individual subpart. 

EQUIPMENT AND CONTROL TECHNOLOGY

3. Pyroprocessing System: : The permittee is authorized to construct a pyroprocessing system consisting of a 

dry process pre-heater/calciner rotary kiln with in-line raw mill that simultaneously dries raw materials using 

the exhaust gas from the kiln, PH/C, or cooler. The preheater is designed with a staged combustion calciner 

and a selective non-catalytic reduction (SNCR) system. The kiln will be equipped with a Low NOX main kiln 

burner capable of burning coal, petroleum coke, natural gas, used oil, and fuel oil. Other equipment includes 

an air heater for use when additional drying capacity is required, and a clinker cooler with cooling air fans, 

and hot air ducting to the kiln, PH/C and/or in-line raw mill. The air heater will be capable of firing fuel oil 

and natural gas. All emissions from the pyroprocessing system are directed to a single stack. The exhaust 

stack shall be no more than 16.5 feet in diameter and no less than 427 feet tall. [Applicant Request] 

4. Kiln Design: The kiln will be designed to process approximately 353 tons per hour of dry preheater feed 

material (including baghouse dust recirculation and excluding dry coal ash) with an annual nominal 

throughput of 2,784,370 tons per year. However, preheater feed rate is ultimately restricted through clinker 

production limitations. [Applicant Request] 

5. NOX Controls

a) Low-NOX Burners and Indirect Firing: The main kiln and calciner will be equipped with Low NOX

burners that will create distinct combustion zones within the flame. An indirect firing system will be used 

to reduce the amount of primary air injected with the fuel used in the main kiln burner. 

b) Staged Combustion in the Calciner (SCC): Introduction of fuel, air and meal to the calciner will be 

staged or sequenced for the reduction of NOX emissions. 

c) SNCR: A selective non-catalytic reduction (SNCR) system shall be designed, constructed and operated to 

achieve the permitted levels for NOX emissions from the pyroprocessing system. The SNCR system will 

consist of an aqueous ammonia and/or urea tank, pumps, piping, compressed air delivery, injectors, 

control system, and other ancillary equipment. Aqueous ammonia and/or urea solution will be injected at 

a location(s) in the preheater/calciner with an appropriate temperature profile to support the SNCR 

process.

19. Supplemental Dioxin/Furan and PM/PM10 Tests: The owner or operator shall notify the Compliance 

Authority prior to initiating any significant change in the feed or fuel used in the most recent compliant 

performance test for dioxin/furan or PM/PM10. For purposes of this condition, significant means any of the 

following: a physical or chemical change in the feed or fuel; the use of a raw material not previously used; a 

change in the LOI of the coal ash; a change between non-beneficiated coal ash and beneficiated coal ash. 

Based on the information provided, the Compliance Authority will promptly determine if performance testing 

pursuant to 40 CFR 63.1349 will be required for the new feed or fuel. A significant change shall not include 

switching to a feed/fuel mix for which the permittee already tested in compliance with the dioxin/furan and 

PM/PM10 emission limits. [62-4.070(3), F.A.C.] 

20. Special Compliance Tests: When the Department, after investigation, has good reason (such as complaints, 

increased visible emissions or questionable maintenance of control equipment) to believe that any applicable 

emission standard contained in a Department rule or in a permit issued pursuant to those rules is being 

violated, it shall require the owner or operator of the emissions unit to conduct compliance tests which 

identify the nature and quantity of pollutant emissions from the emissions unit and to provide a report on the 

results of said tests to the Department. [Rule 62-297.310(7)(b), F.A.C.] 

21. Mercury Compliance Demonstration: 

a. Material Balance Demonstration: The owner or operator shall demonstrate compliance with the 

mercury throughput limitation by material balance and maintaining records of the monthly and rolling 

12-month mercury throughput. Samples of the raw mill feed and all fuels shall be collected each day. 

A single composite daily sample shall be made from all samples collected during a day. A monthly 

composite sample shall be made from each of the daily composite samples. Each monthly composite 

sample shall be analyzed to determine the mercury concentration of the materials representative for the 

month. The analytical methods used to determine mercury concentration shall be EPA or ASTM 

methods such as EPA Method 7471A (Mercury in Solid or Semisolid Waste). No other methods may 

be used unless prior written approval is received from the Department. For each raw material and fuel, 

the monthly mercury throughput rate (pounds per month) shall be the product of the mercury 

concentration from the monthly composite sample and the mass of raw material or fuel used during the 

month. If the mercury concentration is below detection limit or below the limits of quantification, the 
SECTION III. EMISSIONS UNIT SPECIFIC CONDITIONS

D. Pyroprocessing System

Page 17 of 32 

detection limit will be assumed for the concentration of the raw material or fuel. For each month, the 

mass of mercury introduced into the pyroprocessing system (pounds per month) shall be the sum of the 

monthly mercury throughput rate for each raw material and fuel. The consecutive 12-month mercury 

throughput rate shall be the sum of the individual monthly records for the current month and the 

preceding eleven months (pounds of mercury per consecutive 12-months). Such records, including 

calculations and data, shall be completed no later than 25 days following the month of the records. 

b. Mercury Continuous Emissions Monitoring System (Hg-CEMS): Within 60 days following the first year 

of operation, the owner or operator shall install any model of Hg-CEMS that has been demonstrated to 

meet the requirements in Performance Specification 12A (PS-12A), “Specifications and Test Procedures 

for Total Vapor phase Mercury Continuous Monitoring Systems in Stationary Sources,” or that has 

passed verification tests conducted under the auspices of the U.S. Environmental Protection Agency’s 

(EPA) Environmental Technology Verification (ETV) Program. During the subsequent 90 days, the 

owner or operator shall certify the Hg-CEMS. If the vendor provides to the Department verification of 

certification difficulties such that the CEMS cannot be certified by the certification deadline, and every 

reasonable effort has been made to do so, the Department shall grant a reasonable extension of time to 

certify the CEMS. After certification the owner or operator will begin reporting Hg mass emissions 

data. The owner or operator shall adhere to the calibration drift and quarterly accuracy assessment 

procedures in 40 CFR Part 60, Appendix F or 40 CFR Part 75, Appendix B. The 12-month rolling mass 

emissions shall be estimated based on the actual data collected no later than 10 days following the end 

of the month. The CEMS shall only be used as the method of compliance if the owner or operator 

notifies the Department of the intent to use the CEMS in lieu of the procedures described in the 

preceding paragraph. Prior to use of the Hg-CEMS as the method to demonstrate compliance, the 

owner or operator shall submit written notice to the Department, and receive approval for a missing data 

substitution plan. For purposes of this requirement, the first year of operation ends 365 calendar days 

following the first day the kiln produces clinker. 

If, after 365 days of operation of the Hg-CEMS, the CEMS is not to be used as the method of 

compliance and the permittee can document that data from the CEMS is inaccurate or excessively 

invalid, and/or that the CEMS has proven to be unreliable and unreasonably burdensome, the owner or 

operator may request the removal of the Hg CEMS requirements.

compliance with all applicable standards as specified in this permit. The Hg CEMS shall be installed and 

functioning within the required performance specifications following the first year of operation as specified in 

condition No. 21. [Rules 62-4.070(3), 62-210.800, 62-212.400(BACT) and 62-297.520, F.A.C.; 40 CFR 

60.7(a), 60.13(b) and Appendix B; and 40 CFR 63.7(a)(2)] 

29. CEMS Data Requirements: The CEMS shall be installed, calibrated, maintained, and operated in the in-line 

kiln/raw mill stack to measure and record the emissions of CO, NOX, SO2, and THC/VOC in a manner 

sufficient to demonstrate compliance with the emission limits of this permit. The CEMS shall express the 

results in units of pounds per ton of clinker produced, and pounds per hour. Emissions of VOC shall be 

reported in units of the standards (lb/hr, lb/ton of clinker) and ppmvd as propane corrected to 7% oxygen. 

a. Valid Hourly Averages: Each CEMS shall be designed and operated to sample, analyze, and record data 

evenly spaced over the hour at a minimum of one measurement per minute. All valid measurements 

collected during an hour shall be used to calculate a 1-hour block average that begins at the top of each 

hour. Each 1-hour block average shall be computed using at least one data point in each fifteen-minute 

quadrant of an hour, where the unit combusted fuel (or produced clinker) during that quadrant of an 

hour. Notwithstanding this requirement, a 1-hour average shall be computed from at least two data 

points separated by a minimum of 15 minutes (where the unit operates for more than one quadrant of an 

hour). If less than two such data points are available, there is insufficient data and the 1-hour block 

average is not valid. 

• Hours during which there is no kiln feed and no fuel fired are not valid hours. 

• Hours during which the plant is firing fuel but producing no clinker are valid, but these hours are 

excluded from the production-normalized emission rate computation (pounds per ton of clinker). 

These hours are included in any pollutant mass emission rate computation (pounds per hour). 

b. 24-hour Rolling Averages: Compliance with the emission limit for SO2 shall be based on a 24-hour 

rolling average that shall be recomputed after every valid hour as the arithmetic average of that hourly 

average and the preceding 23 valid hourly averages. 

c. 30-day Rolling Averages: Compliance with the emission limits for CO and NOX shall be based on a 30-

day rolling average. Each 30-day rolling average shall be the arithmetic average of all valid hourly 

averages collected during the last 30 operating days. A new 30-day rolling average shall be recomputed 

after every day of operation for the new day and the preceding 29 operating days. For purposes of 

computing these emission limits, an operating day is any day that the kiln produces clinker or fires fuel. 

d. 30-day Block Average: Compliance with the emission limit for VOC shall be based on a 30-day block 

average. Each 30-day block average shall be the arithmetic average of all valid hourly averages 

occurring within each 30 operating-day block and shall be consistent with the averaging period 

specified in 40 CFR 63.1350(h) for THC emissions. 

e. Data Exclusion: Except for monitoring system breakdowns, repairs, calibration checks, and zero and 

span adjustments, each CEMS shall monitor and record emissions during all operations including 

episodes of startups, shutdowns, and malfunctions. Limited amounts of CEMS emissions data recorded 

during some of these episodes may be excluded from the corresponding compliance demonstration 

subject to the provisions of Condition No. 25 in this section. The permittee shall minimize the duration 

of data excluded for such episodes to the extent practicable. 

f. Availability. Monitor availability for each CEMS used to demonstrate compliance shall be 95% or 

greater in any calendar quarter. Monitor availability shall be reported in the quarterly excess emissions 

report. In the event 95% availability is not achieved, the permittee shall provide the Department with a 

report identifying the problems in achieving 95% availability and a plan of corrective actions that will 

be taken to achieve 95% availability. The permittee shall implement the reported corrective actions

minimum monitor availability shall be violations of this permit, except as otherwise authorized by the 

Compliance Authority. 

g. Public Access: Emission data will be available in real time on the company website. 

30. Continuous Flow Monitor: A continuous flow monitor shall be installed to determine the stack exhaust flow 

rate to be used in determining mass emission rates. The flow monitor shall be certified pursuant to 40 CFR 

60, Appendix B, Performance Specification 6. 

31. Baghouse Temperature Monitor: A continuous temperature monitor shall be installed, calibrated, operated, 

and maintained at the inlet to the baghouse for the kiln system exhaust in accordance with the requirements of 

40 CFR 63.1350(f). [NESHAP Subpart LLL in 40 CFR 63]

PERFORMANCE REQUIREMENTS

1. Unconfined Emissions of Particulate Matter

a. No person shall cause, let, permit, suffer or allow the emissions of unconfined particulate matter from 

any activity without taking reasonable precautions to prevent such emissions. Such activities include, 

but are not limited to: vehicular movement; transportation of materials; construction, alteration, 

demolition or wrecking; or industrially related activities such as loading, unloading, storing or handling. 

b. Reasonable precautions shall include the following: 

(1) Landscaping and planting of vegetation. 

(2) Application of water to control fugitive dust from activities such as demolition of buildings, 

grading roads, construction, and land clearing. 

(3) Water supply lines, hoses and sprinklers shall be located near all stockpiles of raw materials, coal, 

and petroleum coke. 

(4) All plant operators shall be trained in basic environmental compliance and shall perform visual 

inspections of raw materials, coal and petroleum coke periodically and before handling. If the 

visual inspections indicate a lack of surface moisture, such materials shall be wetted with 

sprinklers. Wetting shall continue until the potential for unconfined particulate matter emissions 

are minimized. 

(5) Water spray shall be used to wet the materials and fuel if inherent moisture and moisture from 

wetting the storage piles are not sufficient to prevent unconfined particulate matter emissions. 

(6) As necessary, applications of asphalt, water, or dust suppressants to unpaved roads, yards, open 

stockpiles and similar activities. 

(7) Paving of access roadways, parking areas, manufacture area, and fuel storage yard. 

(8) Removal of dust from buildings, roads, and other paved areas under the control of the owner or 

operator of the facility to prevent particulate matter from becoming airborne. 

(9) A vacuum sweeper shall be used to remove dust from paved roads, parking, and other work areas. 

(10) Enclosure or covering of conveyor systems where practicably feasible. 

(11) All materials at the plant shall be stored under roof. Materials, other than quarried materials, shall 

be stored on compacted clay or concrete, or in enclosed vessels. 

(12) Use of hoods, fans, filters, and similar equipment to contain, capture and/or vent particulate 

matter. 

(13) Confining abrasive blasting where possible. 

c. In determining what constitutes reasonable precautions for a particular source, the Department shall 

consider the cost of the control technique or work practice, the environmental impacts of the technique 

or practice, and the degree of reduction of emissions expected from a particular technique or practice.
