Summary

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).

Dates

This rule is effective on August 21, 2017 without further notice, unless the EPA receives adverse comments by July 21, 2017. If we receive such comments, we will publish a timely withdrawal in the Federal Register to notify the public that this direct final rule will not take effect.
