Environmental Protection Agency April 21, 2021 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) submitted by the State of Nebraska on July 16, 2020. This proposed action will amend the SIP to revise title 129 of the Nebraska Administrative Code by removing a portion of the SIP that addresses visible emissions from diesel-powered motor vehicles. Visible emissions from diesel-powered motor vehicles are addressed in the state statute. Therefore, these proposed revisions remove duplicative language that is redundant to the state statute. The proposed revisions do not substantively change any existing statutory or regulatory requirement or impact the stringency of the SIP or air quality nor do they impact the State's ability to attain or maintain the National Ambient Air Quality Standards. The EPA's proposed approval of this rule revision is in accordance with the requirements of the Clean Air Act (CAA).

EPA has received applications to register new uses for pesticide products containing currently registered active ingredients. Pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is hereby providing notice of receipt and opportunity to comment on these applications.

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Sacramento Metropolitan Air Quality Management District (SMAQMD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NOX) from water heaters, boilers and process heaters. We are proposing to approve a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
