  • The EPA is proposing National Uniform Emission Standards for Storage Vessels and Transfer Operations, Equipment Leaks and Control Devices, herein referred to as Uniform Standards. The EPA is also proposing supplemental revisions to the National Uniform Emission Standards General Provisions, which were proposed with the National Uniform Emission Standards for Heat Exchange Systems, signed by the EPA Administrator on November 30, 2011. The proposed Uniform Standards would be referenced, as appropriate, in future revisions to new source performance standards and national emission standards for hazardous air pollutants for individual source categories that are part of the chemical manufacturing and refining industries that have storage vessels and transfer operations, equipment leaks or con...

  • EPA and NHTSA, on behalf of the Department of Transportation, are issuing this joint proposal to further reduce greenhouse gas emissions and improve fuel economy for light-duty vehicles for model years 2017-2025. This proposal extends the National Program beyond the greenhouse gas and corporate average fuel economy standards set for model years 2012-2016. On May 21, 2010, President Obama issued a Presidential Memorandum requesting that NHTSA and EPA develop through notice and comment rulemaking a coordinated National Program to reduce greenhouse gas emissions of light-duty vehicles for model years 2017- 2025. This proposal, consistent with the President's request, responds to the country's critical need to address global climate change and to reduce oil consumption. NHTSA is proposing C...

  • The EPA is proposing amendments to the national emission standards for hazardous air pollutants for the pulp and paper industry to address the results of the residual risk and technology review that the EPA is required to conduct under sections 112(d)(6) and (f)(2) of the Clean Air Act. These proposed amendments include revisions to the kraft pulping process condensates standards; a requirement for 5-year repeat emissions testing for selected process equipment; revisions to provisions addressing periods of startup, shutdown and malfunction; additional test methods for measuring methanol; and technical and editorial changes.
