What the agency says

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) on December 20, 2023. 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. The revision also addresses typographical errors and increases clarity and consistency with EPA's definitions and Alabama's Legislative Services Agency requirements.
