The applicant proposes to modify Twentymile Coal LLC's approved mine plans to <br />include initial development for the Wolf Creek Coal Seam Reserve. Initial Development will <br />include development and placement of long -term support for a 3 -entry rock slope access, <br />development of up to six sets of gate -roads and bleeder entries, and related ancillary activities <br />including, underground dewatering activities and extension of mine ventilation and support <br />systems. The coal mining operation is located approximately 23 miles southwest of Steamboat <br />Springs in Routt County. The State Engineers Office (SEO) offers the following comments on <br />this project: <br />Please note that portions of the site are within an over appropriated stream basin. All <br />surface and ground water diversions in over appropriated areas must be made in priority or <br />must be fully augmented so as to not cause injury to senior water rights. <br />Additionally, if storm water is not diverted or captured in priority, Colorado water law <br />requires it be released, or replacement for evaporation will be required of the operator /owner of <br />the site. The State Engineer's current policy requires that all impounded water be released to <br />the stream system within a maximum of 72 hours after impoundment. Unless captured in <br />priority, impounded water may not be used for any purpose except as approved under a <br />substitute water supply plan or a decreed plan for augmentation. Additionally, If the construction <br />of any ponds /pits exposes ground water, the pond /pit must be backfilled immediately until a well <br />permit issued pursuant to CRS 37 -90- 137(2), allowing the exposure of ground water in a <br />pond /pit, is obtained from the State Engineer. <br />From my review of this site, it appears that several of the well permit types referenced <br />below are applicable to this site. Please note that the dewatering operations if used for any <br />Office of the State Engineer <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303 - 866 -3581 • Fax: 303 -866 -3589 <br />http://water.state.co.us <br />
