Rein, State Engineer/Director Response to Reclamation Permit Application Consideration DATE: January 4, 2018 TO: Amy Eschberger, Environmental Protection Specialist CC: Division 2 Office; District 10 Water Commissioner FROM: Caleb Foy, P.E. RE: Hitch Rack Ranch Quarry, File No. M -2017-049 Operator: Transit Mix Concrete Co. Contact: Andre LaRoche, (719) 475-0700 Secs. 16, 21- 23, Twp. 16S, Rng. 67W, 6th P.M., El Paso County CONDITIONS FOR APPROVAL According to the application, t he proposed operation does not anticipate exposing groundwater, but does anticipate small amounts of water will be incidentally encountered during the mining process. Therefore, the Office of the State Engineer has determined that a well permit to expose ground water issued pursuant to Section 37-90-137(2), C.R.S., and an associated substitute water supply plan/plan for augmentation is unnecessary for the operation as proposed. Based on the above, exposure of ground water must not occur during or after mining operations and any water that is incidentally encountering during the proposed operation must be returned to Little Turkey Creek , or the ground water system within the permit area, immediately without consumption. The proposed operation will consume water by: evaporation, dust control, reclamation, water removed in the mined product, processing, other:. All water used on-site for mining needs shall be a legal supply of water provided by an appropriate supplier. According to the application, the primary source of water for use in mining operations on the site will likely be via purch ase from Colorado Springs Utilities and hauled to the site. The applicant shall confirm the legality of any proposed source of water supply with the Division of Water Resources prior to use in the operation. The application materials indicate that the storm water management plan will include construction of ditches, sediment ponds, and culverts as a part of this project. The applicant should be aware that, unless the storm water detention structures can meet the requirements of a “storm water detention and infiltration facility” as defined in section 37-92-602(8), Colorado Revised Statutes, the structure may be subject to administration by this office. The applicant should review DWR’s Administrative Statement Regarding the Management of Storm Water Detention Facilities and Post-Wildland Fire Facilities in Colorado, attached, to ensure that the notification, construction and operation of the proposed structure meets statutory and administrative requirements. The applicant is encouraged to use Colorado Stormwater Detention and Infiltration Facility Notification
