<br /> <br />Recommend the applicant be requested to clarify the submittal as follows: <br />Please provide a large scale plan for the site, with a cross section that illustrates the <br />relationship of natural slopes, cut and fill slopes for the drill pad if appropriate (if none, <br />confirm that the pad will be placed at a 12.24% slope), the mud pits, the circumferential <br />berm, and the design storage capacity of internal runoff. <br />Runoff from the uphill and side reaches of the berm outslopes would flow off the berm into <br />circumferential ditch flows, with point discharges on both sides. Upland runoff above the <br />site would combine with these flows from off the berm. Please re-design the analysis to <br />address these flows. Include how ditch flow would be managed across the access road to <br />the site (through the berm). Please correct or explain the use of a stiffness factor of 20 for <br />fescue grasses (usually near 2.0). <br />Please discuss how water contained behind the berm will be managed. <br />Cc: Dan Hernandez <br />C:\wpdocs\m r 161 rvs.056.doc <br />Page 3 of 3 pages <br />
