Hickenlooper Governor Mike King Executive Directoi Dick Wolfe, P.E. Director /State Engineer Dear Mr. Foster: We have reviewed your April 11, 2012 letter and the additional information from June 26, 2012 and December 17, 2012 requesting a substitute water supply plan ( "SWSP ") for the DeBeque Pit on behalf of Oldcastle SW Group, Inc. (a.k.a. United) ( "United" or "Applicant "), in accordance with § 37 -90- 137(11), C.R.S. The required fee of $1,593 for the SWSP request has been submitted (receipt no. 3654903). SWSP Operations This SWSP seeks to replace depletions resulting from mining operations at the DeBeque Gravel Pit (M2011 -054), which is located in Section 9, Township 9 South, Range 97 West of the 6th P.M. in Mesa County. The proposed mining operation consists of three phases. During each phase, water will be continuously pumped from a six foot wide dewatering trench surrounding the excavated area into a dewatering sump. The approximate life span of the proposed gravel operation is eighteen years. During this SWSP period United will conduct mining operations under Phase I (11.6 acres) of the mining plan, which is anticipated to last approximately seven years. The depletions that result from the mining operations are evaporation from exposed ground water, water lost in the mined product, and water used for dust suppression. The mine is located in Mesa County in the SW1 /4 of Section 9, Township 9 South, Range 97 West of the 6 P.M. 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. In accordance with approach nos. 1 and 3, you have indicated that a bond has been obtained for $423,630.40 through the Division of Reclamation, Mining, and Safety ( "DRMS ") to assure that depletions from groundwater evaporation do not occur in the unforeseen event, or events, that would lead to the abandonment of the Pit.
