What the agency says

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Mojave Desert Air Quality Management District (MDAQMD or "District") portion of the California State Implementation Plan (SIP). These revisions concern recodification of prohibitory and administrative rules used by the District to regulate air pollutants under the Clean Air Act (CAA or the Act) including volatile organic compounds (VOCs), oxides of nitrogen (NO<INF>X</INF>) and particulate matter (PM). The intended effect is to update the California SIP to reflect the recodified rules.
