infestations; optimize revegetation success for the reclaimed area; and fulfill sound land <br />management objectives, PSCM has developed a noxious weed management program <br />(weed program) as an important component of their ongoing mining, reclamation, and <br />related operations. <br />PSCM's weed program is designed to effect full compliance with applicable <br />provisions, and was developed with reference to the Colorado Weed Management Act <br />(CRS 35-5.5-115), and the CDRMS's "Guideline for the Management of Noxious <br />Weeds on Coal Mine Permit Areas", and in consultation with the local office of the <br />Colorado State University Cooperative Extension Service (CSU-Extension Service, also <br />the Routt County Weed Control agency). PSCM's weed program focuses on those <br />noxious weed species listed by the Colorado Department of Agriculture, and will be <br />modified, as appropriate to address any changes to this list. PSCM's integrated weed <br />program consists of five interrelated components: Prevention, Identification and <br />Mapping, Management Planning and Scheduling, Application of Selected Control <br />Method(s), and Evaluation of Control Effectiveness. <br />Vicinity/Environmental Considerations: <br />1. Slope of site: <br />a. Topography in the PSCM permit area and adjacent areas ranges in elevation from <br />approximately 6,600 to 7,800 feet. The average elevation of the permit area is <br />approximately 7,040 feet. Terrain varies from rolling hills with agricultural fields and <br />rangeland in the northwestern, central, and extreme southern extents of the PSCM permit <br />area and adjacent areas to high ridges and steep slopes within the eastern and <br />southwestern portions. <br />2. Vegetative cover: <br />a. The vegetation in the PSCM permit area is predominantly sagebrush grassland, mountain <br />brush, and mined and reclaimed land, the proposed PSCM portal and surface facilities <br />disturbance area contains reclaimed mine lands and previously undisturbed <br />sagebrush/grassland vegetation. <br />3. Nearest river, creeks, drainages, lakes, etc.: <br />a. The most significant drainage in the PSCM permit area is Grassy Creek which is a <br />perennial stream. It enters at the PSCM permit area at the southwestern margin and flows <br />through the PSCM permit area and north into the Yampa River. There are several <br />unnamed drainages that cross the PSCM permit area that are associated with the steep <br />draws in the east, as well as several of the more gradual, open draws in the central and <br />west (most notably Annand Draw and Scotchmans Gulch), which generally drain to the <br />north and feed into Grassy Creek. The portal facilities are located near one of these <br />tributaries (Little Grassy Creek). Little Grassy Creek parallels the lower access road <br />which is then routed underneath the lower access road to flow north toward the Seneca II <br />Mine Pond 002 (Wadge Pond) and eventually into Grassy Creek. <br />-18-
