-r .~- Mr. Stover Page 2 Preliminary Adequacy Review property. The Division is unable to locate any evidence that notification was performed within the appropriate time frames. C. Page 146 of the permit application states that there are 12 structures within the proposed permit and adjacent areas, which are shown on map 2.04.3(2)(a)-1. The Subsidence Control Monitoring Plan Map, 2.05.6(6)(f)(ii)(c)-1, only shows 11 structures. Please explain the discrepancy and update the map if necessary. 5. It appears when comparing Map 2.05.3(4)-2(a), Post Reclamation Drainage System, with Map 2.05.3{4)-3, Small Area Exemption (SAE), and reading the text on page 105, the location of the SAE does not seem to correspond. The text states the SAE is located in a portion of Area 16 which corresponds with the drainage map. However, when the two maps are overlaid, the SAE marked on the SAE Map is not in Area 16. Please explain this discrepancy and update the map if necessary. 6. Page 61a in the permit application discusses two new monitoring points designated as CE-81-1 and CE-81-2. Where are these point located and which map shows the location? What is the status of these points? 7. Page 63 of the permit application discusses four monitoring locations designated as sample sites A-D. Apparently, these points can be found on Map 2.04.7(2)(a)(b)-1, Surface Drainage Pattern. These points cannot be located on this map. What is the status of these monitoring locations? 8. It is good practice to include in the permit, a description of all monitoring locations. For example, is discharge obtained using a flume, or other method, and how is quality obtained? What instruments are used and what is' the-sampling protocol? This should be addressed in regards to surface and ground water to be included within the permit. 9. Rules 4.10.3(2), 4.09.2(7), and 4.05.4(4) require a permanent diversion ditch that diverts all surface drainage from the area above the underground development waste disposal area from the crest and the face of the disposal area. Review of Map 2.05.3(4)- 2(a), Post Reclamation Drainage System, does not show an upper diversion ditch. However, review of Map 2.05.3(4)-2, Existing Drainage System, shows that an upper diversion ditch did exist. The Division realizes that the disposal area is reclaimed, but we must resolve this issue. I would like to examine this area in the field with you, when we meet at Red Canyon on April 21, 1993 at 8 a.m., before this issue is discussed any further.
