Jaynes A. Kiger <br />April 9, 2010 <br />Page 2 <br />(PAP) needs to be updated and revised. Please provide a new North SAE demonstration <br />that would result from the construction of the methane drainage facility and update the <br />PAP accordingly. <br />3. During the construction phase of the drill pad and methane drainage facility, straw bales <br />or sediment fence should be utilized to ensure the protection of Elk Creek and to prevent <br />additional contribution of dissolved or suspended solids to streamflow. Please ensure <br />that adequate sediment control throughout the construction phase is provided for Elk <br />Creek particularly along the eastern edge of the construction site. <br />4. The borehole will be drilled in close proximity to Elk Creek, approximately eighty west <br />of the creek. Adequate safeguards such as an appropriate length of steel surface casing <br />may be necessary at this drill site to protect both Elk Creek and alluvial groundwater in <br />this area. Please submit a well completion diagram for the Divisions review. The well <br />completion information will be reviewed prior to approval of this technical revision. <br />5. Revised pages 2.05 -11 a and l lb appear to contain erroneous information pertaining to <br />the proposed new Elk Creek Fansite Methane Drainage Facility. It appears that the new <br />facility is incorrectly labeled as the Bear Creek Fansite Methane Drainage Facility and its <br />description is contained in two places under both Elk Creek and Bear Creek listings on <br />pages 2.05 -11a and 11b, respectively. The new description also indicates a 620' borehole <br />whereas the application cover letter requests a 210' borehole. Please clarify this and if <br />appropriate, revise these pages accordingly. <br />If you have any questions, please contact me. <br />Sincerely, <br />M P L) Ph, <br />Michael P. Boulay <br />Environmental Protection Specialist <br />C: Denver File <br />
