Environmental Protection Agency April 6, 2017 – Federal Register Recent Federal Regulation Documents

Consistent with the Federal Advisory Committee Act, Public Law 92463, the Environmental Protection Agency (EPA) is giving notice of an upcoming public meeting of the Assumable Waters Subcommittee convened under the National Advisory Council for Environmental Policy and Technology (NACEPT). The Assumable Waters Subcommittee will provide advice and recommendations as to how the EPA can best clarify assumable waters for dredge and fill permit programs pursuant to Clean Water Act section 404(g)(1). The EPA is undertaking this effort to support states and tribes that wish to assume the program. Similar to the parent NACEPT, the subcommittee represents a diversity of interests from academia, industry, non-governmental organizations, and local, State, and tribal governments. Due to unforeseen administrative circumstances, EPA is announcing this meeting with less than fifteen calendar days' notice. Meeting agendas and materials will be posted at www.epa.gov/cwa-404/assumable- waters-sub-committee.

EPA is proposing approval of State Implementation Plan (SIP) revisions submitted by the State of Connecticut for purposes of implementing the 2008 ozone National Ambient Air Quality Standards. The SIP revisions consist of a demonstration that Connecticut meets the requirements of reasonably available control technology for the two precursors for ground-level ozone, oxides of nitrogen (NOX) and volatile organic compounds (VOCs), set forth by the Clean Air Act with respect to the 2008 ozone standards. Additionally, we are proposing approval of three related regulations that limit air emissions of these pollutants from sources within the State. This action is being taken in accordance with sections 172, 182, and 184 of the Clean Air Act.

The Environmental Protection Agency (EPA) is amending the electronic reporting requirements for the National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units (also known as the Mercury and Air Toxics Standards (MATS)) to allow for the temporary submission, through June 30, 2018, of certain reports using the portable document file (PDF) format and to correct inadvertent errors. With this action owners or operators of Electric Utility Steam Generating Units (EGUs) will be able to continue to use temporarily a single electronic reporting system for MATS data submissions, to rely on correct language for mercury (Hg) relative accuracy test audit (RATA) requirements, and to rely on the correct acceptance criterion for ongoing quality assurance test requirements for Hg RATAs. This extension will allow the EPA the necessary time to develop, implement, and test the code necessary so that all MATS reports required to be submitted electronically can be submitted using the Emissions Collection and Monitoring Plan System (ECMPS) Client Tool.
