and are moderately -deep to deep, well- drained, and have loam to find - sandy -loam surface <br />textures (Soil Survey Staff, Natural Resources Conservation Service, U.S. Department of <br />Agriculture. Web Soil Survey. Custom Soil Resources Report for Routt Area, Colorado, Parts of <br />Rio Blanco and Routt Counties. <br />http : / /websoilsurvey.nres.usda.gov /accessed [04/07/08]). <br />The only potential for erosion problems would be associated with the drill -pads, however given <br />the very limited size of the pads, and the proposed drainage control measures, this potential is not <br />significant. Upon completion of drilling activities the pads will be reclaimed and revegetated. <br />POLLUTION REPORT <br />Air Pollution Potential: The proposed exploration activities will have little or no impact on local <br />and regional air resources. The limited vehicular traffic to and from the drill sites has minimal <br />potential to generate any significant quantity of dust from the existing county and ranch roads. <br />The rotary drill -rigs will use foam/water mixture and an air mist to remove cuttings from the <br />borings, thus minimal dust will be generated during the drilling process. <br />Water Pollution Controls: The water pollution control plan focuses on the drill -sites where <br />implementation of Best Management Practices (BMPs), i.e. rock check dams, silt fence, straw <br />bales, etc., and limited pad size will effectively control runoff and sediment from the sites. <br />Additionally, mud pits will be excavated at each of the drill -sites to contain any drilling fluids <br />used during drilling operations. Following completion of the drilling and related activities the <br />mud pits will be backfilled and the pad area reclaimed and revegetated. <br />A Stormwater Management Plan (SWMP) was prepared for the 2008 exploration activities. The <br />SWMP describes the controls PSCM uses to manage stormwater discharges from areas disturbed <br />by the exploration activities. These are the same methods that will be used during the 2012 <br />exploration activities. <br />Please note that a Construction Stormwater Discharge Permit is not required. Discussions in June <br />and July Of 2008 between Peabody Energy representatives and Water Quality Control Division <br />(WQCD) staff confirmed that a permit is not required. The basis for the exclusion is: <br />• an individual disturbance is less than 1.0 acres <br />• cumulative disturbance is less than 5.0 acres <br />• the individual disturbances are not part of a "Common Plan of Operations" <br />• a "Common Plan of Operations" applies to individual disturbances that are within 0.25 <br />miles of each other, or which are connected by roads or pipelines <br />Noise Abatement: None of the proposed drilling -sites are within 0.5 miles of a private residence <br />or near RCR #27. PSCM plans to schedule drilling operations on a 12 -hour per day basis <br />(approximately 7:OOam to 7:OOpm); however, PSCM requests permission to conduct operations <br />on a 24 -hour per day basis if unforeseen delays cause the project to fall behind schedule. The <br />exploration activities at any one drill -site should take about seven days; deeper holes (e.g., 1,900 <br />Peabody Sage Creek Project 5 April 2012 <br />
