On June 13, 2022, the public comment period begins for the proposed State Implementation Plan Revision: Regional Haze Program (2018 – 2028). The comment period ends July 14, 2022.

Public Notice Information

On Jan. 10, 2017, the U.S. Environmental Protection Agency (EPA) finalized changes to the Regional Haze Rule, which requires each state to submit periodic state implementation plan (SIP) revisions addressing regional haze visibility impairment. ADEQ is required under Arizona Revised Statutes § 49-458.01(A) to submit to the EPA administrator SIP revisions to address regional haze requirements. The proposed SIP revision demonstrates that the State of Arizona has met the requirements of the regional haze program for the second implementation period. ADEQ is requesting the U.S. Environmental Protection Agency approve the proposed plan as a revision to the Arizona SIP.
