Air Plan Revisions; California; San Diego County Air Pollution Control District and Mojave Desert Air Quality Management District

The Environmental Protection Agency (EPA) is proposing to approve revisions to the San Diego County Air Pollution Control District (SDCAPCD) and Mojave Desert Air Quality Management District (MDAQMD) portions of the California State Implementation Plan (SIP). These revisions concern negative declarations for the Control Techniques Guidelines (CTG) for the Oil and Natural Gas Industry (Oil and Natural Gas CTG). We are taking comments on this proposal to approve the SDCAPCD and MDAQMD negative declarations into the California SIP. We plan to follow with a final action.
