AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.
SUMMARY: The EPA is proposing to approve revisions to the New Mexico State Implementation Plan (SIP). these revisions concern two separate actions. First, we"are proposing to approve revisions to regulations on Emissions Inventories (EIs) submitted by stationary sources ofair pollutants. EIs are critical for the efforts ofState; local, and federal agencies to attain and maintain the National Ambient Air Quality Standards that EPA has established for criteria pollutants such as ozone, particulate matter, and carbon monoxide. The revisions add new definitions, modify existing definitions, and require stationary sources ofair pollutants located in New Mexico outside ofBemalillo County to report emissions location information, PM2.5 emissions, and ammoniaemissions to New Mexico Environment Department (NMED). The revisions also allow NMED to require speciation ofhazardous air pollutants for emissions reporting. Second, we are proposing to approve revisions to the General Provisions of the NMAC (20.2.1 NMAC - General Provisions). We are proposing to add a new definition for SignificantFigures into the New Mexico SIP. EPA is proposing to approve these two actions pursuant to section 110ofthe Federal Clean Air Act.2
