Start Preamble


Environmental Protection Agency (EPA).


Proposed rule.


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 of State, 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 of Bernalillo 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 of the Federal Clean Air Act.

In the final rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

For additional information, see the direct final rule, which is located in the rules section of this Federal Register.
