New Mexico State Implementation Plan

The U.S. Clean Air Act requires each state to develop air quality protection plans called State Implementation Plans (SIPs). SIPs are not single documents; rather, they are a collection of programs, plans, state regulations and policies that states use to enforce state and federal air quality standards and rules. There is only one SIP for each state; all subsequent submittals or changes are considered SIP revisions to that single comprehensive plan, although you will also hear these individual revisions referred to as “SIPs.” State statute gives NMED the authority to act as the lead agency for all purposes related to the SIP. US EPA has codified its approval of the New Mexico SIP in the Code of Federal Regulations, at 40 CFR 52 Subpart GG.Whether or not a state regulation is part of the NM SIP can be determined by referring to the SIP/Non-SIP Index.

Getting Involved in the SIP Process

States are required by law to involve the public, through hearings and opportunities to comment, in the development of SIP revisions. The New Mexico Environmental Improvement Board (EIB) is given the authority under state statute to adopt rules and plans that are included in New Mexico’s SIP. Once adopted by the EIB, rules and plans must be submitted to the U.S. Environmental Protection Agency (EPA) for approval. The New Mexico SIP applies throughout New Mexico, except for Bernalillo County (Albuquerque) and Indian lands. The State of New Mexico’s SIP is housed at the EPA Region VI office in Dallas, Texas.
