"F? 2 201, <br />RE: Ashbaugh Gravel Pit, File No. M-2005-060 } D'v+sfor? jb (%eQ&Irlation, <br />Operator: Weld County Public Works Mining and Safety <br />Contact: David Bauer, 970-304-6496 <br />Section 15, Twp 7 North, Rng 59 West, P.M., Weld County <br />CONDITIONS FOR APPROVAL <br />® The application is submitted for a conversion from an existing 110 gravel pit containing 10 acres to a 112 <br />gravel pit, which would contain 139.7 acres. The proposed operation as indicated in the original 110 <br />permit does not anticipate exposing groundwater. Therefore, exposure of ground water must not occur <br />during or after mining operations. <br />® The applicant has identified that water used for dust control for this operation can be obtained and <br />hauled from the Weld County-owned wells at other gravel pits. The applicant will need to ensure the <br />water used for dust control by the gravel operation at the Ashbaugh Pit is included in the substitute water <br />supply plan ("SWSP") approved for the other gravel pits. <br />COMMENTS: If stormwater runoff is intercepted by this operation and is not diverted or captured in priority, it <br />must be released to the stream system within 72 hours. This may require a discharge permit from CDPHE- <br />WQCD. Otherwise, the operator will need to make replacements for evaporation. <br />The applicant may contact the State Engineer's Office with any questions. <br />4 <br />Office of the State Engine) <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303-866-3581 • Fax: 303-866-3589 <br />http://water.state.co.uS
