## Abstract

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving a New Mexico State Implementation Plan (SIP) revision for the repeal of State regulations titled 20.2.20 NMAC (Title 20: Environmental Protection, Chapter 2: Air Quality (Statewide), Part 20: Lime Manufacturing Plants--Particulate Matter of the New Mexico Administrative Code) that cover particulate matter emission standards for lime manufacturing plants and lime hydrators in the State of New Mexico. The EPA is approving the repeal of the regulations based on the CAA section 110(l) demonstration contained in the New Mexico submittal, which provides that the SIP revision will not interfere with attainment and maintenance of the national ambient air quality standards (NAAQS) or any other CAA requirement.
