69i16i96 16:50 DES ~93 832 ~ III IIIIIIIIIIIII III •• sss ... ,/' To: Ric Pocius, Brian Peters From: Lane Wyatt Date: July 12, 1996 RE: Maryland Creek lunch Conditional Use Permit N0.066 D66 Per your request I have reviewed the Maryland Creek Conditional Use Permit Application for general wmments and conformity to the Areawide Water Quality Management Plan (208 Plan). The proposed gavel mining operation at Maryland Creek Ranch is am approved use within the A-1 zoning district, it is the concrete.plsnt, asphalt plant and processing plam which require the Conditional Use Permit. The application goes into some detail on the mining operatioq however, provides very little information on the actual uses requiring this application. Therefore the following wmments are general in nature. 1. The application indicates that there will be no new impacts, in general because the operation is essentially beimg moved across the highway. This seems to imply that the existing site will be fully reclaimed prior to commencing operation at the new site. 2. The existing agricultural ditches that are proposed to remain on site after cotrversion to a mining operation should be protected with berms or other techniques to in.~rre that they do not became conduits to carry sediment and other pollutants off site. Runoff drainage systems should be designed to contain the runoff om site and utilize in5ltration to prevent off site sedimentation problems. (see Polity 3, 208 Plan) 3. This facility, and the wnditional uses contemplated, appear to require a CPDES stormwater permit for industrial activities. This permit should address many of the potential issues of wncern such as protection from spillage of petrochemicals stored on site, disposal of wash water, operation and maintenance of any n-noff treatment systems, etc. lfthe facility is required by Colorado Deparunent of health to have this permit it should be a condition for approval. (see Policy 4, 208 Plan)
