Cheryl Signs, P.E. 4Cheryl Signs Engineering 109 East Fourth Avenue Denver, CO 80203 Re: Heintzelman Pit o. 116, Substitute Water Supply Plan (WDID 0502525) DRMS File NoYM-2009-018 (0503010) Section 32, T3N, R67W of the 6 P.M. Water Division 1, Water Districts 5, Weld County Approval Period: July 1, 2011 through June 30, 2013 Contact Phone Number for Ms. Cheryl Signs: 303 - 778 -7653 Dear Ms. Signs: a■ DEPARTMENT OF NATURAL RESOURCES 514/SP mac DIVISION OF WATER RESOURCES August 26, 2011 Division of Reclamation This letter is in response to your application of June 30, 2011 requesting a substituttliwlate sgt y plan ( "SWSP ") for a sand and gravel pit to be operated by Varra Companies, Inc. ( "VCI" or Applicant ") in accordance with § 37 -90- 137(11), C.R.S. The Applicant shall be responsible for compliance with this SWSP, but the State Engineer's Office may also pursue the landowner, for eventual compliance. The required fee of $1,593 for the SWSP has been paid. SWSP Operations The Heintzelman Pit is located in the E 1/2 of the E 1/2, Section 32, Township 3 North, Range 67 West of the 6 P.M. This SWSP seeks to replace depletions resulting from the mining at the Heintzelman Pit No. 116. The depletions that result from the mining operation over the.first two years of existence include evaporation from exposed ground water, dust suppression, dewatering and water lost with the mined product. Because the pit is located on historically irrigated land, historical return flow obligations will also need to be accounted for in this SWSP. The proposed replacement of depletions and maintenance of return flows will come from a combination of either direct replacement or storage in 112 Reservoir (WDID 0504001), Dakolios Reservoirs (WDID 0504003) and Von Ohlen Reservoir (WDID 0504002) of; 1) four shares of the Last Chance Ditch, 2) 4 shares of the Rural Ditch, and 3) junior water rights decreed in case no. 2001 CW274. To the extent possible, return flow obligations from the direct replacement or storage will be replaced by credits from Hayseed Ditch as decreed in case no. 1990CW174. In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado Division of Reclamation, Mining, and Safety ( "DRMS "), all sand and gravel mining operators must comply with the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for the protection of water resources. The April 30, 2010 letter from DRMS requires that you provide information to DRMS to demonstrate you can replace long term injurious stream depletions that result from mining related exposure of ground water. The DRMS letter identifies four approaches to satisfy this requirement.
