10 percent or must show adequate protection on all valves and lines to prevent damage and <br />potential spill from impact by machinery, etc. <br />18. The application indicates that no hazardous materials will be stored or used on site. This is not <br />possible with fuel tanks for processing machinery and asphalt batch plant materials being used <br />and stored there. Please revise this statement accordingly. <br />19. Please submit a tamarisk and Russian olive management plan for this site. <br />Exhibit E -Reclamation Plan <br />20. Please provide details for compaction of fill material in highwall backfilling and peninsula <br />construction operations. <br />21. To improve the proposed wildlife habitat, DMG recommends that the pit slopes grade be varied <br />from 3H:1 V to 6H:1 V. <br />22. Please revise the reclamation plan so it specifies ripping only in areas to be topsoiled and <br />revegetated. The ripping should be performed immediately prior to topsoil replacement. <br />23. Please revise the revegetation plan to specify leaving heavy furrows in the tilled topsoil to provide <br />moisture concentration and shade areas that promote better conditions for successful vegetation <br />establishment. <br />24. The reclamation plan indicates that revegetation will be considered adequate when erosion is <br />controlled and noxious weeds are not present in significant amounts. Though this is a key criteria <br />of the reclamation goal, the operator must be aware that revegetation of the site will not be <br />considered successful until it meets the requirements of rule 3.1.10, <br />25. In fhe absence of documentation that provides reasonable assurance houses will be constructed <br />on the peninsulas, DMG will require that they be revegetated to rangeland and meet the <br />requirements of the reclamation plan and Rule 3.1.10 to be released. <br />26. The final contours of the site should indicate grading toward the pit to address sediment control <br />during reclamation and vegetation establishment. <br />27. Please specify timing for application of seed. Include timing during the year and with respect to <br />completion of backfilling and topsoil application for each phase. <br />Exhibit F -Reclamation Plan Mao <br />28. Please indicate the wetland area on the reclamation plan map. <br />Exhibit G - Water Information <br />29. Please commit to not mining within 2 feet of the average upper limit of the water table until the <br />augmentation plan and well permit for the pit have been secured. <br />30. Please address the requirements of Rule 6.4.7(2)(a} regading wells, stack ponds, and springs. <br />31. Please affirmatively state in this exhibit, if an NPDES permit has been applied for or secured for <br />this operation. <br />
