EOR Energy, LLC v. Illinois Environmental Protection Agency, No. 17-3107 (7th Cir. 2019)
Annotate this CaseIn 2007, the Illinois Environmental Protection Agency (IEPA) brought charges before the Pollution Control Board against EOR Energy and AET Environmental under the Illinois Environmental Protection Act, 415 ILCS 5/1–5/58, for transporting hazardous‐waste acid into Illinois, storing that waste, and then injecting it into EOR’s industrial wells. EOR unsuccessfully argued in state courts that the IEPA and the Board did not have jurisdiction over EOR’s acid dumping. EOR asserted that it was not injecting “waste” into its wells but was merely injecting an acid that was used to treat the wells and aid in petroleum extraction so that the Illinois Department of Natural Resources had exclusive jurisdiction under the Illinois Oil and Gas Act, 225 ILCS 725/1. EOR then sought a federal declaratory judgment. The district court dismissed the case, citing the Eleventh Amendment and issue preclusion. The Seventh Circuit affirmed, “emphatically” rejecting the “undisguised attempt to execute an end‐run around the state court’s decision.”
