Environmental Protection Agency June 21, 2017 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is providing notice of the availability of data on emission allowance allocations to certain units under the Cross-State Air Pollution Rule (CSAPR). EPA has completed preliminary calculations for the first round of allocations of allowances from the CSAPR new unit set-asides (NUSAs) for the 2017 control periods and has posted spreadsheets containing the calculations on EPA's Web site. EPA will consider timely objections to the preliminary calculations (including objections concerning the identification of units eligible for allocations) and will promulgate a notice responding to any such objections no later than August 1, 2017, the deadline for recording the first-round allocations in sources' Allowance Management System accounts.

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Mojave Desert Air Quality Management District (MDAQMD), Northern Sierra Air Quality Management District (NSAQMD), and San Diego County Air Pollution Control District (SDCAPCD) portions of the California State Implementation Plan (SIP). These revisions concern aerospace assembly, rework, and component manufacturing operations; emissions statements and recordkeeping; and definitions, respectively. We are approving local rules that regulate these sources and issues under the Clean Air Act (CAA or the Act).
