Why is ADEC updating adoptions by reference?

ADEC is adopting updated federal regulations so that applicable requirements are included in permits.

Where can I find the updated adoption by reference documents?

The current and proposed updated adoption by reference documents can be found at: 18 AAC 50 Reference Materials

Why is ADEC proposing to repeal the ice fog and SO₂ special protection areas regulations?

ADEC is proposing to remove those regulations and cross-references to them from the Federally-approved Alaska State Implementation Plan (SIP) because these older regulations were not mandatory measures required by the Clean Air Act (CAA) and/or EPA regulations, and were established by ADEC as measures  to address specific situations that have since been resolved. Their removal will not interfere with any applicable requirement concerning attainment and reasonable further progress or any other applicable requirement of the CAA.
