Proposed Air Quality Regulations and Plans

Following are summaries of proposed new air quality regulations and proposed amendments to existing regulations and the New Mexico State Implementation Plan.  For updates, please periodically check back at this webpage. For information on new policies and procedures for air quality permitting, please go to the What's New in Permitting page.


Streamlining of 20.2.99 NMAC – Conformity to the State Implementation Plan of Transportation Plans, Programs and Projects. A public hearing has been scheduled for July 11, 2014 to consider the repeal and replacement of 20.2.99 NMAC. This regulation, sometimes called “Transportation Conformity,” was first adopted on October 20, 1994 as a required element of the New Mexico State Implementation Plan. The purpose of the rule is to ensure that federal transportation projects do not contribute to air quality problems in certain areas of the state. Previous amendments were required to match changes in the federal rule. This proposed repeal and replacement deletes large portions of the current rule; those portions which apply to the state’s role in implementing the federal rule will be retained. A summary of the changes, public notice of the hearing and other documents are linked below.

Revisions to New Mexico's State Implementation Plan for Nitrogen Dioxide under the Clean Air Act Section 110(a)(2). The U.S. Environmental Protection Agency revised the National Ambient Air Quality Standard for nitrogen dioxide on January 22, 2010.  The SIP certification matrix outlines the requirements of section 110(a)(2)(A) through (M) of the federal Clean Air Act (CAA) and addresses how New Mexico will implement, maintain and enforce the revised NAAQS for nitrogen dioxide.

Revisions to New Mexico's State Implementation Plan for Sulfur Dioxide under the Clean Air Act Section 110(a)(2). The U.S. Environmental Protection Agency revised the National Ambient Air Quality Standard for sulfur dioxide on June 2, 2010.  The SIP certification matrix outlines the requirements of section 110(a)(2)(A) through (M) of the federal Clean Air Act (CAA) and addresses how New Mexico will implement, maintain and enforce the revised NAAQS for sulfur dioxide.

Repeal of 20.2.88 NMAC - Emission Standards for New Motor Vehicles.  A public hearing has been scheduled for November 7, 2013 to consider the repeal of 20.2.88 NMAC.  This regulation, sometimes called “Clean Cars,” was first adopted in 2007 to apply the California motor vehicle emissions standards, or “California standards,” within New Mexico beginning with model year 2011. The start date was later revised to 2016.  When the Clean Cars regulation was adopted, the California standards were more stringent than the federal motor vehicle emissions standards.  However, since that time the federal programs have been revised to achieve the same emissions reduction as the California standards.  As a result, the administrative burdens of implementing the Clean Cars regulation now outweigh the potential benefits of having a State program.

Amendment of 20.2.77 NMAC and 20.2.82 NMAC to Incorporate Federal Rules by Reference.  A public hearing has been scheduled for November 7, 2013 to consider amending 20.2.77 NMAC and 20.2.82 NMAC to incorporate by reference the new rules, corrections, revisions, and amendments to the federal New Source Performance Standards (“NSPS”) and Maximum Achievable Control Technology Standards for Source Categories of Hazardous Air Pollutants (“MACT”), respectively, which were promulgated by the U.S. Environmental Protection Agency and published in the Federal Register from January 1, 2011 to August 29, 2013.

Adoption of Proposed Sulfur Dioxide Limited Maintenance Plan for Grant County, NM. The Environmental Improvement Board approved the Sulfur Dioxide Limited Maintenance Plan for Grant County, NM on October 8, 2013.

Section 175A of the Federal Clean Air Act (CAA) requires states to develop state implementation plans to provide for the maintenance of the National Ambient Air Quality Standards (NAAQS) for those areas that have violated a standard (referred to as a nonattainment area) and have sufficient data to prove that area is now in compliance with the standard. In February 2003, NMED submitted to EPA a Redesignation Request and Maintenance Plan for the Grant County 24-hour SO2 nonattainment area. This submittal was subsequently approved by EPA on September 18, 2003.

Clean Air Act Section 175A(b) requires states to revise maintenance SIPs ten (10) years after EPA approves an area’s initial maintenance plan. The proposed State Implementation Plan revision to the Grant County Sulfur Dioxide Maintenance plan has been developed to satisfy the 10 year plan revision as required under Section 175A of the Federal Clean Air Act. The proposed State Implementation Plan revision does not impose any new regulatory requirements.

Repeal of 20.2.98 NMAC– Conformity of General Federal Actions to the State Implementation Plan. The Environmental Improvement Board approved repeal of 20.2.98 NMAC on October 8, 2013.

The repeal of 20.2.98 NMAC - Conformity of General Federal Action to the State Implementation Plan was in response to the Environmental Protection Agency’s (EPA) amendments to the federal general conformity rule, 40 CFR Part 93, Subpart B on March 24, 2010. A portion of the amendments to the federal general conformity rule were in response to revisions made in August 2005, to the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) that removed the requirement for states to adopt and submit General Conformity State Implementation Plans under the Clean Air Act. Before this revision to SAFETEA-LU, states were required to adopt regulatory State Implementation Plans that corresponded to the federal general conformity rule.

In its March 2010 revision to the federal general conformity rule, EPA made the adoption and submittal of General Conformity State Implementation Plans optional rather than mandatory for states. The New Mexico Environment Department believes it would be the most beneficial to the state to opt out of the general conformity State Implementation Plan requirement, as allowed by the revised federal general conformity rule, by repealing Part 98.

Revisions to 20.2.70 NMAC - Operating Permits and 20.2.74 NMAC - Permits - Prevention of Significant Deterioration (PSD). The Department is proposing to amend 20.2.70 NMAC and 20.2.74 NMAC in response to two final actions taken by the U.S. Environmental Protection Agency amending related federal rules. The proposed amendments would defer until 2014 the consideration of CO2 emissions from biogenic sources when determining whether a stationary source meets the PSD and Title V applicability thresholds, and revise the PSD rules to establish plantwide applicability limitations (PALs) for GHG emissions.  The Environmental Improvement Board unanimously adopted these amendments at a public hearing on December 3, 2012. The amendments will become effective 30 days after filing with the New Mexico State Records Center. The amendments will become effective on February 6, 2013.

The New Mexico Environment Department Air Quality Bureau proposes to amend 20.2.72 NMAC Construction Permits. The proposed amendments to 20.2.72 NMAC consist of allowing 20.2.72.202 exemptions in streamline permit applications and amending the requirements for portable source relocations.
