3.3.9 Names of Receiving Waters and Wetlands <br />Without engineered controls, stormwater runoff from the operation area could <br />potentially discharge onto adjacent undeveloped government and private lands. There <br />are two drainages adjacent to the property. The first drainage to the west is Basin <br />Creek, which has recently been modified with drop structures to reduce sedimentation. <br />The second area is a network of unnamed drainages that flow through several road <br />drainage ditches and culverts to the south. This entire area currently drains to the <br />southeast of the property and eventually into the Animas River. There are no wetlands, <br />wells or other bodies of water within the Animas Glacial gravel pit operation area. <br />4.0 SITE MAP <br />The site map will be amended as changes occur in design, development, mining or <br />maintenance of the site. The site map of the facility is provided in Appendix C. <br />The site map provides the following information: <br />• Site boundaries <br />All mining, processing and batching activities are limited to within the <br />property boundaries; which are shown on the site map. <br />• All area of ground surface disturbance <br />The limits of the area of ground surface disturbance have been identified on <br />the site map. <br />• Area of cut and fill <br />There are no significant areas of permanent areas of cut and /or fill other <br />than along the access road. <br />• Areas used for storage of building materials, equipment, soil or waste <br />There will be areas for long term storage of building materials, equipment, <br />soil and possibly some non -toxic waste. <br />• Locations of any dedicated asphalt or concrete batch plants <br />There will be dedicated asphalt and /or concrete batch plants located at this <br />site, which will be shown on the site map as final plans are formulated. <br />• Locations of all structural BMPs <br />Proposed erosion and sediment control structures are identified on the site <br />map and will be updated as needed. <br />• Locations of non - structural BMPs - as applicable <br />Non - structural BMPs, such as preservation of existing vegetation, temporary <br />seeding (TS), permanent seeding (PS), mulching, soil retention blankets (SRB), <br />vegetative buffer strips, surface roughening (SR) or soil scarification (e.g., <br />contour ripping) and sod stabilization, will be shown on the site map. <br />• Springs, streams, wetlands, and other surface waters <br />Existing topography and features are identified on the SWMP site map. <br />Animas Glacier SWMP February 2012 <br />P. 6 <br />
