Wafer Division 1, Water District 4, Larimer County Dear Mr. Raines: We have reviewed your letter of November 16, 2004 requesting renewal of the above referenced substitute water supply plan for a sand and gravel pit. The required fee of $217.00 for the renewal of this substitute supply plan has been submitted. The original supply plan was approved on becember 16, 1999 and it was most recently approved in a letter dated September 2, 2003. The anticipated net depletion for this plan is 10.5 acre-feet per year, which includes evaporation from up to 2.0 acres of ground wafer exposed after December 31, 1980. According to the information submitted, no ground water was exposed within the reclamation permit boundary prior to January 1, 1981. The mining operation has continuously dewatered directly back to the Big Thompson River since 2000. The estimated dewatering rate at the Wagner/Kauffman Pit No. 3 site is approximately 1000 gallons per minute. The total estimated net depletions from this operation remain unchanged from the previous plan. Water used at the Wagner/Kauffman Pit No. 3 will include 4.6 acre-feet of evaporative loss, and 5.9 acre-feet of water lost with 200,000 tons of mined product. No phreatophyte credit has been applied to this plan. The proposed source of replacement for this pit is a lease of up to 15.0 acre-feet of fully consumable water from the City of Loveland, including a 4 percent transit loss from Green Ridge Glade Reservoir to Wagner/Kauffman Pit No. 3. The monthly depletions and replacement requirements are found on the attached table. I hereby approve the proposed substitute water supply plan in accordance with §37-90- 137(11), C.R.S., subject to the following conditions: 1. This plan shall be valid through December 31, 2006 to coincide with the replacement water lease term. If Phis plan wi(I not be made absolute by a water court action by the plan's expiration date, a renewal request must be submitted to this office with the statutory fee (currently $217) no later than November 15, 2006.
