C 0 L 0 R A D 0 <br /> Division of Water Resources <br /> AZT" Department of Natural Resources <br /> Response to Consideration Construction Materials Reclamation Permit Conversion Application <br /> DATE: September 20, 2021 <br /> TO: Eric C. Scott, Environmental Protection Specialist <br /> FROM: Sarah Brucker, Water Resources Engineer dl�5 <br /> RE: Golden Mine, Permit No. M-1976-007-UG <br /> Applicant/Operator: Denver Brick Company <br /> Phone Number: (940) 383-7569 <br /> Pt. WY2 Section 16, Twp. 3 South, Rng. 70 West, 6th P.M. <br /> Water Division 1, Water District 7, Jefferson County <br /> CONDITIONS FOR APPROVAL <br /> 0 The proposed operation does not anticipate exposing groundwater. Therefore, exposure of <br /> groundwater must not occur during or after mining operations. <br /> 0 Any stormwater runoff intercepted by this operation that is not diverted or captured in priority <br /> must be released to the stream system within 72 hours; otherwise the operator will need to make <br /> replacements for evaporation. <br /> 0 Water is proposed to be used at the site for dust control purposes. The applicant will need to <br /> document that the water was obtained from a legal source and provide such documentation to this <br /> office upon request. <br /> COMMENTS: The Golden Mine is a surface mining operation located on the west side of Highway 93 just <br /> north of the city of Golden. The primary commodity mined at the site is clay for the making of bricks. <br /> The site is proposed to be reclaimed to its previous use of rangeland upon completion of mining. <br /> The subject application is for the conversion of the existing 110c permit to a 112c permit. The <br /> application seeks to add 61.15 acres to the currently permitted 9.0 acres for a total of 70.15 acres within <br /> the permit area. The additional permitted acreage will allow for a consistent stockpile and processing <br /> area for the life of the mine. <br /> Groundwater is not anticipated to be encountered during mining or reclamation operations. Precipitation <br /> and snowmelt pool at the base of the mine face and infiltrate into the ground within 72 hours. Perimeter <br /> berms will direct precipitation around the mined areas and stockpiles to the toe of the hogback. Should <br /> any precipitation intercepted by this operation not infiltrate into the ground or be released to the stream <br /> system within 72 hours, the operator will need to make replacements for evaporation. <br /> Water will be used at the site for dust control purposes and will be applied by a water truck. <br /> Approximately 4,000 gallons of water per day will be required for dust control during processing, which <br /> will occur for a period of approximately three weeks once every 18 months. The source of water for dust <br /> control purposes was not specified. The water must be obtained from a source permitted or decreed for <br /> this use. <br /> The Division of Reclamation Mining Et Safety and/or the applicant may contact the State Engineer's Office <br /> with any questions. <br /> COlO� <br /> 1�12 Sher,rnan Street, Rou ni 821, Denver' (_ ��.��� ��� <br /> J r r ilia L�rn r 0cluri Gibbs, Ex c.i I.i���: )i® (_�,���i I M��: r� � ��, L,�t Er7 i i�.�:r:°L�i•®�:Lam°' O <br /> 1876* <br />
