<br /> <br />C-E4-CGS: MT 3 1~~4. s. Pavlik 2 <br />Vegetation: <br />2. The NCEG plans to utilize reference areas for comparison of revegetation <br />success. The Sagebrush reference area is not located within the permit area <br />boundary. The surface owner of the land where the reference area is located <br />is the U.S. Bureau of Land Management. Does NCEG have access rights to <br />the reference area, and will the reference area will be managed in a similar <br />manner to the reclaimed areas? <br />3. Permit page 3-70 contains a printing error in the standard deviation formula. <br />Please resubmit this page so it is legible. <br />That concludes my actual unresolved concerns, comments noted while conducting the review <br />follow and do not need explanation from NCEG. Several concerns that I had identified <br />have previously been stipulated in the permit. These stipulations should remain as a part <br />of the permit. <br />NCEG has no defined woody plant density standard within the permit. DMG added <br />Stipulation No. 23 to the permit, which requires the operator to establish 1000 live stems <br />per acre for woody plant revegetation success standard. <br />NCEG has not defined the species diversity they will obtain to achieve revegetation success. <br />DMG attached Stipulation No. 19 to the permit which requires the establishment of a <br />minimum of four cool season grasses and two forb species with each species comprised of <br />not less than 3% relative cover and not more than 40% relative cover. <br />No permitting actions have transpired since the reclamation cost estimate was last calculated <br />by DMG in November 1992. Reclamation costs have not changed since the last estimate <br />either. The reclamation estimate is sufficient. The bond held by the Division is sufficient <br />as well, for existing disturbances on site. Should additional construction commence on the <br />site, the operator will need to provide appropriate bond in accordance with Stipulation <br />No. 24. <br />NCEG has committed to replacing an average of 12-16 inches of topsoil throughout the <br />20 acres of disturbed area. A survey of stockpiled topsoil verified there is 59,682 cu.yd. of <br />salvaged topsoil on site. This volume is adequate to redistribute topsoil to an average depth <br />of 22 inches. <br />NCEG's permit appears to be in compliance with these portions of the regulations. <br />m: \ c o a l \j h b\ C84065 M T. b l p <br />Xcc: C-84-065 MT public file <br />
