TR-48 Adequacy Review Comments (4/30/98) Issues from 10/30/97 Letter Previously Resolved. 2. Concern adequately addressed; issue resolved. 3. Requested update to B seam Mine Plan Map (Map 120) was submitted, along with extensive updates to mine plan narrative in Section III "Mine Description". We have the following comments regazding the Section III amendments: a) The third paragraph in Section 111.7.h, on amended page III-20, references a location "where County Road 65 crosses above LW-19." This is erroneous, apparently a relic from an earlier version of the mine plan. The reference should be appropriately amended. b) The fourth paragraph in Section II[.A.7.1, on amended page III-24, contains an apparent contradiction which should be clarified. The third sentence states that "monitoring of the five control points... continued until cessation of subsidence was accurately documented." The fourth sentence states that, if "any of these conventional survey monuments experience more than 1.0 feet of residual subsidence, an additional aerial photographic flight, subsidence map and report will be prepared for presentation to CMLRD within one yeaz following cessation of subsidence." It is not clear how this determination would be made, if monitoring has been discontinued. c) The first paragraph of Section III.A.8, on amended page III-28, references the proposed B seam vent shaft. Reference to a security fence and an access road do not correspond to the most recent version of the plan as presented in the TR-49 application, which specifies that the shaft opening will be grated rather than fenced, and that the road to the site will be a light use road. The paragraph should be amended as appropriate. d) The discussion of drill site sediment control at the top of amended page III-31 should be revised to include reference to rock check sediment [raps, and Illustration 44 "SAE Demonstration for Typical Degasification Borehole Pads". e) Discussion of the prep plant water circulation system in Section III.B.2, on amended page III-32, should be amended to reflect the approved disposal of prep plant thickener water in the sealed 1st Longwall District of the D-Seam Mine. f) On page III-33, in Section III.B.4, the narrative indicates that the temporary coal storage area and remaining topsoil stockpile would be reclaimed and reseeded by the fall of 1997. This work had not been done at the time of the most recent inspection, and needs to be completed as soon as possible.
