Here is the opinion in Pawnee Well Users Inc. v. Wolfe (Colo.).
The court’s summary:
2013 CO 67. No. 12SA13. Pawnee Well Users, Inc.v. Wolfe, State Engineer.
Ground Water Regulation—Administrative Law and Procedure—Rules, Regulations, and Other Policymaking—Judicial Review of Administrative Proceedings.
The Supreme Court held that the water court erred in invalidating a basin-specific rule of the final Produced Nontributary Ground Water Rules (Final Rules) known as the Fruitland Rule, based on a stipulated agreement between the State Engineer and the Southern Ute Indian Tribe. Another Final Rule—known as the Tribal Rule—states: “These Rules and regulations shall not be construed to establish the jurisdiction of either the State of Colorado or the Southern Ute Indian Tribe over nontributary ground water within the boundaries of the Southern Ute Indian Reservation.”
The Tribal Rule does not and cannot divest the State Engineer of his authority to promulgate the Final Rules governing water extracted during oil and gas production throughout the state, including nontributary groundwater. By passing HB 1303, the General Assembly authorized the State Engineer to adopt rules to assist with the administration of nontributary ground water extracted in the course of coalbed methane production and other oil and gas development in Colorado, thus authorizing the State Engineer to promulgate the Fruitland Rule. Because administrative agencies powers and duties as given by the legislature, the State Engineer cannot establish or disestablish his own jurisdiction.
Further, because the Fruitland Rule was issued pursuant to the authority granted in HB 1303—authority that was not divested by the Tribal Rule—it follows that the water court erred in labeling the Fruitland Rule an “advisory” rule and requiring the State Engineer to obtain a judicial determination that he had authority to administer nontributary ground water within the Southern Ute Indian Tribe’s Reservation’s boundaries. The Court therefore reversed the water court’s order and remanded the case for further proceedings.
