Box 197 <br /> Conejos, Colorado 81129 <br /> Re: Use of Well No. 2, Case No. W-953—Randall Robins <br /> Well located within the SW%Section 29, T33N, R9E, NMPM <br /> Dear Ms. DeHerrera: <br /> I have received your May 5, 2014 e-mail inquiry as to a legal water supply for an asphalt and concrete <br /> batch plant operation to be located within the existing Valdez Gravel Pit area. The pit is located within <br /> the NW'''A Section 32, T33N, R9E, NMPM, about one mile southwest of Antonito. Conejos County is <br /> currently doing an administrative review of an application by Randall and Lou Ann Robins (Robins) to <br /> locate the batch plant at the Valdez Pit. You have inquired as to a legal water supply for the asphalt and <br /> concrete batch plant operations. <br /> I have previously worked with Mr. Robins to determine the legal use of Well No. 2, Case No. W-953, <br /> Permit No. 5312-F. Well No. 5312-F was the main water supply for the sawmill operation located within <br /> the SW% Section 29,T33N, R9E, NMPM and very near Antonito. The sawmill was in operation from <br /> approximately 1961 through 1974. Well permit no. 5312-F was issued on March 24, 1964. The well was <br /> completed to a depth of 150 feet on April 16, 1964. The well was adjudicated for 100 gpm for <br /> commercial use on November 20, 1975. <br /> The position I took in my September 27, 2013 letter to Scott Johnson, Robins'engineer, was that the <br /> historic use of well no. 5312-F averaged 9.0 acre-feet/year for the period 1964—2012. The estimated <br /> maximum annual withdrawal was 37.0 acre-feet during the high production years of 1964— 1974. I <br /> approved the use of the well to supply water for the proposed gravel pit I batch plant within the NEV4 of <br /> Section 31,T33N, R9E, NMPM(Robins Pit). I do not see a conflict with the use of that same well as a <br /> water supply for an asphalt/concrete operation on adjacent land. <br /> Therefore, so long as these volumetric limitations are not exceeded and the well is used consistent with <br /> the decree, I will not oppose the use of the well to supply water for the proposed gravel pit/ batch plant <br /> within the existing Valdez Pit within the NW% of Section 32,T33N, R9E, NMPM. The average annual <br /> use must not exceed 9.0 acre-feet in any five consecutive year period as detailed in State Engineer <br /> Policy 2013-01. The maximum withdrawal cannot exceed 37.0 acre-feet in any calendar year. <br /> Production from the well must be metered in accordance with the well measurement rules set forth in <br /> Case No. 05CW12. <br /> 44Summit Engineering Job Number: 240328CE 24 <br /> 719-589-6147 <br /> Alamosa, CO <br />
