Environmental Protection Agency September 21, 2020 – Federal Register Recent Federal Regulation Documents

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 PlantsParticulate 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.

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), in a letter dated February 27, 2020. The revision modifies the State's air quality regulations as incorporated into the SIP by changing the definition of ``volatile organic compounds'' (VOC) to be consistent with federal regulations. EPA is approving this SIP revision because the State has demonstrated that these changes are consistent with the Clean Air Act (CAA or Act).
