Read Me: New Mexico SIP-Approved Air Quality Control Regulations in this web site.

The New Mexico regulations in this New Mexico directory are what I have determined to be the New Mexico State Implementation Plan (SIP) approved State regulations.

These regulations are to be used as a supplement to, NOT as a replacement for, the regulations promulgated in the Federal Register and codified in the U.S. Code of Federal Regulations (CFR). Due to the magnitude of the project, questions may arise on an approved section of the SIP. If such questions arise as to the content of the approved SIP or any portion of the SIP, then the Federal Register approval action and the CFR will serve as the final determination.

Due to the magnitude and complexity of the project, there may be errors in the files. Please notify me at one of the addresses below of any errors you find in the files.

Albuquerque/Bernalillo County and the State of New Mexico have separate SIPs. This directory contains the SIP-approved regulations for both the Albuquerque/Bernalillo County Air Quality Control Board and the New Mexico State Environmental Improvement Board.

I can answer general questions about the regulations.
I WILL NOT attempt to interpret regulations.
