In re Delta Energy Center
Mr. Rob Simpson filed this petition for review on behalf of himself and Helping Hand Tools (collectively, “Petitioners”). Petitioners allege that Delta Energy Center (“Delta”), which operates a combined cycle gas-fired power plant, obtained an amendment of a license in March 2017 that effectively modified a prevention of significant deterioration (“PSD”) permit issued to Delta under the Clean Air Act, 42 U.S.C. § 7475.
