On July 9, 2025 WESTAR sent comments to EPA related to anticipated revisions to the Regional Haze Rule. While there is no draft rule to review or comment on, we asked EPA to consider several core principles to the regional haze program as they draft the rule. WESTAR also reiterated the importance of cooperative federalism when undertaking such impactful rulemaking. You can read the full letter here.
In a Federal Register notice, EPA proposed to extend the SIP submittal deadline for the third implementation period from July 2028, to July 2031. WESTAR commented on the proposal in the Federal Register. WESTAR agrees with EPA’s proposal and additionally, requested that EPA extend the fourth, and subsequent implementation period deadlines so that they are all ten to fifteen years long. This is consistent with Section 169A of the Clean Air Act. You can read WESTAR’s comments here.
