4 The State Engineer need not complete the requirements of Section 37-90-137(2)(b)(II) related to 600 feet of spacing between wells because the process in Rule 6.4 provides notice to all wells within 1 mile.
Any approval to extract Artificially Recharged groundwater from Nontributary Groundwater Aquifers outside the Denver Basin aquifers, which approval was given prior to the effective date of these rules, as evidenced by an unexpired well permit issued prior to the effective date of these rules, shall remain valid and shall continue to be administered under the terms and conditions of such unexpired permit.
All new and replacement Extraction Well permits issued on or after the effective date of these rules are subject to these rules.
