Current through Register Vol. 43, No. 1, October 31, 2024
Section 335-3-8-.01 - Standards For Portland Cement Kilns(1) Applicability. The requirements of this Rule apply only to Portland cement kilns in the Counties of Autauga, Bibb, Blount, Calhoun, Chambers, Cherokee, Chilton, Clay, Cleburne, Colbert, Coosa, Cullman, Dallas, Dekalb, Elmore, Etowah, Fayette, Franklin, Greene, Hale, Jackson, Jefferson, Lamar, Lauderdale, Lawrence, Lee, Limestone, Macon, Madison, Marion, Marshall, Morgan, Perry, Pickens, Randolph, Russell, Shelby, St. Clair, Sumter, Talladega, Tallapoosa, Tuscaloosa, Walker, and Winston with process rates of at least the following: (a) Long dry kilns-12 short tons per hour (TPH) of clinker produced;(b) Long wet kilns-10 short TPH of clinker produced;(c) Preheater kilns-16 short TPH of clinker produced; and(d) Precalciner and preheater/precalciner kilns-22 short TPH of clinker produced.(2) Definitions. For the purpose of this Rule, the following definitions apply: (a) "Clinker" means the product of a Portland cement kiln from which finished cement is manufactured by milling and grinding.(b) "Long Dry Kiln" means a kiln 14 feet or larger in diameter, 400 feet or greater in length, which employs no preheating of the feed. The inlet feed to the kiln is dry.(c) "Long Wet Kiln" means a kiln 14 feet or larger in diameter, 400 feet or greater in length, which employs no preheating of the feed. The inlet feed to the kiln is a slurry.(d) "Low-NOX Burners" means combustion equipment designed to reduce flame turbulence, delay fuel/air mixing, and establish fuel rich zones for initial combustion.(e) "Mid-kiln System Firing" means secondary firing in kiln systems by injecting solid fuel at an intermediate point in the kiln system using a specially designed fuel injection mechanism for the purpose of decreasing nitrogen oxide (NOX) emissions through: 1. Burning part of the fuel at a lower temperature; and2. Reducing conditions at the fuel injection point that may destroy some of the NOX formed upstream in the kiln burning zone.(f) "Portland Cement" means a hydraulic cement produced by pulverizing clinker consisting essentially of hydraulic calcium silicates, usually containing one or more of the forms of calcium sulfate as an interground addition.(g) "Portland Cement Kiln" means a system, including any solid, gaseous or liquid fuel combustion equipment, used to calcine and fuse raw materials, including limestone and clay, to produce Portland cement clinker.(h) "Precalciner Kiln" means a kiln where the feed to the kiln system is preheated in cyclone chambers and utilize a second burner to calcine material in a separate vessel attached to the preheater prior to the final fusion in a kiln which forms clinker.(i) "Preheater Kiln" means a kiln where the feed to the kiln system is preheated in cyclone chambers prior to the final fusion in a kiln which forms clinker.(3) Standard Requirements. After May 31, 2004, the owner or operator of any Portland cement kiln subject to this Rule shall not operate the kiln during May 1 through September 30 unless the kiln has installed and operates during May 1 to September 30 with at least one of the following: low-NOX burners, mid-kiln system firing, alternative control techniques or reasonably available control technology approved by the Director and the EPA as achieving at least the same emissions decreases as with low-NOX burners or mid-kiln system firing.(4) The owner or operator subject to the requirements of paragraph (3) of this Rule above shall comply with the requirements as follows: (a) By May 31, 2004, submit to the Department the identification number and type of each Portland cement kiln subject to this Rule, the name and address of the facility where the kiln is located, and the name and telephone number of the person responsible for demonstrating compliance with paragraph (3); and(b) Submit data, electronically and in a format prescribed and provided by the Department, which reports the total NOX emissions from May 1 through September 30 of each year as follows: 1. Annual reporting. For each kiln, beginning with emission year 2004 and every year thereafter, by March 31st of the calendar year following the emission year being reported, the data specified in 40 CFR, §§ 51.122(c)(1) and (2) must be submitted to the Department.2. Triennial reporting. For each kiln, beginning with emission year 2005 and every third year thereafter, by March 31st of the calendar year following the emission year being reported, the data specified in 40 CFR,51.122(c)(3) must be submitted to the Department.3. Year 2003 reporting. For each kiln, by March 31, 2004, the data specified in 40 CFR, § 51.122(c)(3) must be submitted to the Department.4. Year 2007 reporting. For each kiln, by March 31, 2008, the data specified in 40 CFR, § 51.122(c)(3) must be submitted to the Department.(5) By May 31, 2004, the owner or operator of a kiln subject to this Rule shall submit to the Department a demonstration of compliance with the requirements of paragraph (3). If compliance is being achieved by use of prescribed equipment, for example low-NOX burners or mid-kiln system firing, the demonstration of compliance shall be written certification to the Department that this equipment is installed and in use. If compliance is being achieved by use of alternative control techniques, approved by the Director and EPA, demonstration of compliance shall be specified by the Director and EPA. In case of compliance proposed to be achieved by use of alternative control techniques, a plan for compliance demonstration shall be submitted to the Department by May 1, 2003. Upon receipt, the Department shall immediately forward a copy of the plan to the EPA. By November 1, 2003, the Director shall specify in writing to the owner or operator of the kiln how compliance shall be demonstrated, this specification consistent with methods and requirements specified by the EPA following its review of the submitted plan.(6) By December 31 of each year, beginning in 2004, the owner or operator of a Portland cement kiln subject to this Rule shall submit to the Department a written certification that compliance with the requirements of paragraph (3) has been maintained during that year's five-month period May 1 though September 30. The methods of determining that this compliance has been maintained shall be as specified on the major source operating permit issued for the facility at which the kiln is operated.(7) Beginning May 1, 2004, the owner or operator of a Portland cement kiln subject to this Rule shall maintain records for May 1 through September 30 of each year that include the data as follow: (a) The date, time, and duration of any startup, shutdown, or malfunction in the operation of the cement kiln or its emissions monitoring equipment or of any scheduled maintenance activity that affects NOx emissions or emissions shall be retained on-site for a minimum of 2 years following the monitoring; (b) The results of any compliance testing; and (c) Other data required by permit to be maintained. (8) The records listed in paragraph (7) of this Rule calendar year for which they are made and shall be made available to the Department for review upon request.(9) The requirements of this Rule shall not apply to periods of scheduled maintenance activities that affect NOX emissions.
