| E9-10206 | National Emission Standards for Hazardous Air Pollutants From the Portland Cement Manufacturing Industry | Proposed Rule | EPA is proposing amendments to the current National Emission Standards for Hazardous Air Pollutants (NESHAP) from the Portland Cement Manufacturing Industry. These proposed amendments would add or revise, as applicable, emission limits for mercury, total hydrocarbons (THC), and particulate matter (PM) from kilns and in-line kiln/raw mills located at a major or an area source, and hydrochloric acid (HCl) from kilns and in-line kiln/raw mills located at major sources. These proposed amendments also would remove the following four provisions in the current regulation: the operating limit for the average hourly recycle rate for cement kiln dust; the requirement that cement kilns only use certain type of utility boiler fly ash; the opacity limits for kilns and clinker coolers; and the 50 parts per million volume dry (ppmvd) THC emission limit for new greenfield sources. EPA is also proposing standards which would apply during startup, shutdown, and operating modes for all of the current section 112 standards applicable to cement kilns. Finally, EPA is proposing performance specifications for use of mercury continuous emission monitors (CEMS), which specifications would be generally applicable and so could apply to sources from categories other than, and in addition to, portland cement, and updating recordkeeping and testing requirements. | 2009-05-06 | 2009 | 5 | https://www.federalregister.gov/documents/2009/05/06/E9-10206/national-emission-standards-for-hazardous-air-pollutants-from-the-portland-cement-manufacturing | https://www.govinfo.gov/content/pkg/FR-2009-05-06/pdf/E9-10206.pdf | Environmental Protection Agency | 145 | EPA is proposing amendments to the current National Emission Standards for Hazardous Air Pollutants (NESHAP) from the Portland Cement Manufacturing Industry.
