Approval and Promulgation of Air Quality Implementation Plans; New Mexico; Revisions

to Emissions Inventory Reporting Requirements, and General Provisions

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 of air 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 of air

pollutants located in New Mexico outside ofBemalillo County to report emissions location

information, PM2.5 emissions, and ammonia emissions to New Mexico Environment Department

(NMED). The revisions also allow NMED to require speciation of hazardous 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

Significant Figures into the New Mexico SIP. EPA is proposing to approve these two actions

pursuant to section 110 ofthe Federal Clean Air Act.
