The attached file is the final preamble and rule for the portland cement manufacturing industry National Emission Standards for Hazardous Air Pollutants (NESHAP). This is the preamble and rule that was signed by the EPA Administrator on May 14, 1999 and published in the Federal Register June 14, 1999. These maximum achievable control technology (MACT) standards for the portland cement industry are being promulgated under authority of Section 112 of the Clean Air Act. The attached file also includes two final emission test methods that may be used to measure hazardous air pollutants from portland cement kilns. These test methods may be used by portland cement plant owners/operators to help them determine if they are major sources of hazardous air pollutants. These test methods may also be found on the TTN under the "EMTIC" bulletin board.
Among other things, the preamble provides a summary of the changes since proposal; background information and data on the industry; provides the estimated impacts of the final rule; and provides a summary of the major comments received on the proposed rule, and our responses to these comments. The rule will apply to both new and existing portland cement plants that are major sources of hazardous air pollutants. New and existing portland cement plants that are not major sources of HAPs (i.e., area sources) will only be subject to the cement kiln dioxin/furan and THC emission limits and associated monitoring and recordkeeping requirements. Note that the rule will not apply to cement kilns that burn hazardous waste; these cement kilns will be subject to MACT standards applicable to hazardous waste combustors, which were proposed in the FR on April 19, 1996. However, all other HAP emission sources at a cement plant (such as the clinker cooler, raw mill, finish mill, etc.) will be covered by this rule, regardless of whether the cement kiln at the plant burns hazardous waste.
