Environmental Protection Agency January 23, 2018 – Federal Register Recent Federal Regulation Documents

Whenever a new or revised National Ambient Air Quality Standard (NAAQS) is promulgated, the Clean Air Act (CAA) requires states to submit a plan for the implementation, maintenance, and enforcement of the standard, commonly referred to as infrastructure requirements. The Environmental Protection Agency (EPA) is proposing to approve the Alaska State Implementation Plan (SIP) as meeting specific infrastructure requirements for the fine particulate matter (PM2.5) NAAQS.
