Walther Executive Director Michael B. long Division Director Re: Crites Sand and Gravel Pit, File M-99-022, Ne~v 110c Application, Preliminary Adequacy Review. Dear Mr. Crites, I have completed my adequacy review of the above-named permit application, and have identified a fe~v technical issues to be clarified. Overall the operation appears to be straightforward, and the application materials are well presented. The items described in this letter must be responded to prior to the decision date, which is presently set for 5/10/99. i have listed my questions and concerns below in the order of the exhibit to which they pertain. Please arrange your responses similarly also. Exhibit A - Legal Description The description does not include the Section numbers. Numerous other references in the application adequately show that the two areas of activity are located in Sections 25 and 36. You may comment on [his if you wish, but I am considering this exhibit to be adequate at this time. Exhibit B -Site Description There is the question of onsite or nearby structures, to which you initially stated that there are none. You have depicted several structures on the maps, however, including the canal, roads and existing pit. At this time, by virtue of the pre-operation inspection by the Division, we know that there are fencelines and at least one water well. Please provide the additional information clarifying the locations of these structures, and provide the names of their owners. Exhibit C - Mining Plan Your proposed activities include washing of the mined aggregate. Please clarify how the washed (or wet mined, if applicable) materials will be placed on the site to facilitate drainage into the pit. Will any of the surface be graded to allow such drainage control? If so, please clarify how it is to be reclaimed after mining is finished. Exhibit D -Reclamation Plan Please describe any specific activities you will perform (or avoid) to assure sufficient weed control. Likewise, please describe any erosion control activities on the affected area (slopes on the hillside, slopes in the pit, topsoil stockpiles, etc.). I have some further questions below under Exhibit E. Exhibit E -Maps The newer mining map (received here on 418/99) shows roads to the [vvo areas of activity. The roads to each area show a short segment to be missing. The access road passes by the recharge pit/stockpile area at a distance of 100- 200 fee[, and the north end of Ure road is separated from the northern pit by about 50 feet. Please clarify the issue of road locations and access.
