This the proposed preamble and rule for the portland cement manufacturing industry National Emission Standards for Hazardous Air Pollutants (NESHAP), as published in the Federal Register (FR) on March 24, 1998. This is the preamble and rule that was signed by the EPA Administrator on March 9, 1998, but edited and formatted for publication in the FR. These maximum achievable control technology (MACT) standards for the portland cement industry are being proposed under authority of Section 112 of the Clean Air Act.

The proposal includes three proposed 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 owner/operators to help them determine if they are major sources of hazardous air pollutants. These proposed test methods may also be found on the TTN under "EMTIC" bulletin board.
Among other things, the preamble provides background information and data on the industry, its processes, its emissions, and their air pollution controls; provides the estimated impacts of the proposed rule; and provides the rationales for the selection of applicability requirements, emission limits, and monitoring requirements in the proposed rule.
The proposed rule would 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) would only be subject to the cement kiln dioxin/furan emission limits and associated monitoring and recordkeeping requirements. Note that the proposed rule would not apply to cement kilns that burn hazardous waste; these cement kilns would 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.) would be covered by this proposed rule, regardless of whether the cement kiln at the plant burns hazardous waste.
