Under § 37-92-501(1), C.R.S., the State Engineer may adopt rules to assist in the performance of his or her duties to administer, distribute, and regulate the waters of the state ("water rule power"). Under § 37-80-104, C.R.S., the State Engineer shall make and enforce such rules with respect to deliveries of water as will enable the state of Colorado to meet its interstate compact commitments ("compact rule power"). The water rule power and the compact rule power are governed by the procedures of the Determination Act and not by the APA. See Simpson v. Cotton Creek Circles, LLC (In re Rules Governing New Withdrawals of Ground Water), 181 P.3d 252, 264 (Colo. 2008); In re Rules & Regulations Governing Water Rights, 196 Colo. 197, 202 (Colo. 1978). Whenever the State Engineer adopts any rule under the water rule power or the compact rule power, the provisions of this rule shall apply. All other rulemaking shall be subject to the rulemaking procedures under Rule 7 below. To the extent any provision of this rule conflicts with any current or future provision of the Determination Act, Management Act or an interstate compact, the procedures of the Determination Act, the Management Act or interstate compact shall apply.
Notice shall be made as required by § 37-92-501(2)(g), C.R.S. and any other applicable provisions of the Determination Act or Management Act, as may be amended from time to time.
Any person desiring to protest a proposed rule may do so in the manner as provided in § 37-92-304, C.R.S. for the protest of a ruling of a referee, and the water judge shall hear and dispose of the same as promptly as possible. See § 37-92-501(3)(a), C.R.S. Any such protest must be filed by the end of the month following the month in which such proposed rules are published. See id.
Under section 37-92-304(9), C.R.S., appellate review shall be allowed to any judgment and decree of the water judge. Under § 13-4-102, C.R.S., water cases involving Adjudications are appealed to the Colorado Supreme Court.
