(i) The proposed pit will intersect the water table. A dewatering trench will be <br />maintained around the active pit area which will drain to the west and terminate in a <br />settling and discharge pond immediately to the west of the pit area. Once sufficient <br />settling of solids has occurred, water will return to the La Plata River via natural <br />dissipation and ground discharge. In disturbed areas outside the active pit area, a storm <br />water containment berm will be constructed which will guide water to the dewatering <br />trench and subsequently to the settling /discharge pond. Silt fencing will be placed at the <br />runoff locations of the topsoil and overburden stockpiles to ensure their contents stay in <br />place until completion of reclamation of the site. Please see Exhibit E for the locations of <br />these components. <br />0) A Substitute Water Supply Plan (see Exhibit F) is currently being developed for this <br />project and will be submitted for approval from the State Engineer's Office. This plan <br />will likely utilize the existing water right of 1 cfs attached to this parcel and/or other water <br />sources within the La Plata River watershed to mitigate any impacts to existing water <br />rights as a result of this project. <br />(k) Refuse and acid or toxic producing materials are not anticipated during mining. If <br />they are encountered they will be disposed of and handled in a manner consistent with <br />CDOT and OSHA specifications. <br />(1) A Substitute Water Supply Plan (see Exhibit F) is currently being developed for this <br />project and will be submitted for approval from the State Engineer's Office. This plan <br />will likely utilize the existing water right of l cfs attached to this parcel and/or other water <br />sources within the La Plata River watershed to mitigate any impacts to existing water <br />rights as a result of this project. Stormwater management measures consisting of berms, <br />and silt fencing will be implemented on-site to minimize stormwater pollution. Please <br />see Exhibit E for the locations of these components. <br />(m) All aggregate material removed. from the site will be processed at the crusher facility <br />on-site. The crushing process consists of a Nielsons, Inc. portable aggregate processing <br />unit presently permitted with the Colorado Department of Public Health and <br />Environment. Main components of the plant are one primary crusher, two cone <br />crushers, one vertical shaft impact crusher with screens and associated conveyors. No <br />chemicals will be used in the processing of aggregates. Please see Exhibit E for the <br />locations of these components. <br />(n) This pit will be utilized to obtain approximately 155,325 metric tons of aggregates <br />for use in the production of hot bituminous pavement (BP). All materials will be <br />utilized in the CDOT Project #NH1601-046 - improvements to SH 160 between Wildcat <br />Canyon and Cherry Creek. <br />(o) No incidental products are anticipated as part of the proposed operation.
