4 <br />• <br />1 <br />Mr. Robert J. Olson - 3 - May 16, 1985 <br />E. What scaled distance equation or table is used to determine the <br />maximum weight of the explosives used? Please provide this <br />documentation. <br />~F. What is the proposed maximum distance fly rock will travel? <br />" Please describe in more detail the roads that are proposed to be constructed <br />"as necessary". These roads will have to be depicted on the mining map of <br />Exhibit C. (Please be aware that all road construction must be within the <br />permit area.) <br />Will the permit boundaries be posted so that the operations people are aware <br />of the mining boundaries? If not, how does the operator propose to stay <br />within the permit boundaries? <br />Please provide the required information pursuant to Rule 2.12(4)(d) and Rule <br />2.12(4)(e). <br />Exhibit E -Reclamation Plan <br />Has BLM agreed to the proposed final land use? <br />How will runoff from above the quarry get into the stream below the quarry <br />considering channels will be obliterated during reclamation (as depicted on <br />the Reclamation Map - Exhibit F). <br />Please provide a cross-sectional diagram of the proposed reclaimed slope. <br />Point 4.c. addresses areas A & B. Please depict these areas on a map. <br />Point 4.g. addresses a test plot, however, no further information is <br />provided. Please submit documentation of this test plot. <br />~he last paragraph of this exhibit addresses no revegetation will occur if the <br />test plot is unsuccessful. To substantiate this point the operator cites Rule <br />6.5(h)(V). The Division directs the attention of the operator to Rule <br />1.56(f)- Since vegetation is occuring at the site naturally, the Division <br />believes the site can be revegetated and reclaimed. If the operator still <br />believes revegetation for wildlife habitat is impossible, the Division will <br />recommend denial of this application pursuant to Rule 1.56(F). Therefore, the <br />Division suggest the operator retract this last paragraph from the application <br />and perform the necessary activities to successfully reclaim the site to <br />wildlife habitat. <br />The second paragraph on the first page of this exhibit specifies "a slope of 2 <br />to 1 or less". To avoid confusion, does "or less" imply slopes no steeper <br />than 2:1 (eg.: 2.5: 1 or 3:1)? <br />The Division is encouraged by the number of various shrub species to be <br />included in the seed mixture. However, with only one grass species the <br />Division is concerned that there is a severe potential of erosion at this <br />site. The basis for this belief is due to our experience with the slow growth <br />
