None of these species are currently listed on the BLM Colorado Sensitive Species List found at www.blm.gov /co /st/en/BLM Programs/botany /Sensitive Species List _.html. The vegetative cover on CM -25 may be classified as scattered to sparse. Most Pinyon- Juniper stands do not reach over twenty feet in height. 4.3 Existing Stormwater Structures The portal is located near the head of a small drainage located below the access road for the site. The access road is located uphill of the mining site and provides an excellent location for runoff control structures to intercept offsite drainage and route runoff around the mining area. Bordering the site are two small offsite basins that route runoff from upland areas ( Offsite Basin 10 and Offsite Basin 20) toward the mine. Offsite Basin 10 is generally intercepted by roadways above the mine and directed to the north into a relatively large retention pond existing immediately north of the mine site. This appears to be a non - discharging retention pond designed previously to protect the existing Uravan tailings disposal site (immediately to the east) from offsite run -on. Offsite Basin 20 borders the south side of the site and produces runoff directed generally north toward the mine. This runoff is, for the most part, intercepted by the existing mine access roadway running along the southern portion of the mine area. It generally drains east along the roadway to a natural drainage channel existing near the southeast corner of the site. This channel turns to the south and discharges into Hieroglyphic Canyon, the large ephemeral drainage which flows east and enters the San Miguel River near Uravan. 5.0 Site Manager The site manager for the CM -25 will be responsible for implementing BMPs at the site during the operation of the mine, bi- annual stormwater inspections, maintenance of stormwater inspection records, and oversight of reclamation efforts once mining activities are completed. The Vice President of Mining for Cotter Corporation, Glen Williams, is responsible for implementing and maintaining the SWMP for the CM -25 site.
