to the west from the II-W Substation to the mine shop area is owned by Seneca Coal Company and has not been requested for permanent retention within the SL-2 application. The short segment of YVEA owned power line within the South Extension was included in the release request area, but falls within the area to be excluded from the Division's SL-2 proposed approval. Summary and Conclusions The Division has completed its review and evaluation of the Phase I bond release request submitted by Seneca for the Seneca II-W Mine. Specific areas as described in this document that do not meet the criteria for Phase I bond release are listed below and are shown on Figure 2 of this document. Exclusion Areas • South Extension Area 402.85 acres • A Pit Highwall Slump 10.0 acres • Channel 006-NE2 0.23 acres • Channe1006-E1 0.36 acres • Light-Use (LU) Road LU-1 A 0.20 acres • LU-1 0.83 acres • LU-3 and LU-4 2.35 acres • Oil Well Road 0.93 acres • Road `J' 0.94 acres • Culvert I-1 Area 0.03 acres • Scraper Road Exclusion 12.10 acres Total 430.89 acres excluded Based upon a review of the mine permit, the applicant's bond release application, and site inspections, the Division finds that SCC has completed backfilling, grading and drainage reestablishment at all other areas of the Seneca II-W Mine for which Phase I bond release was requested in accordance with the approved reclamation plan. The reclaimed areas included within the original permit area of the SL-2 bond release request have been restored to the approximate original contour of the pre-mining landscape. Slopes conform with post-mining contours as shown on the approved Postmining Topography Map of the permit (Exhibit 20-2) and, with exception of the "A" Pit highwall slump area noted in this report, appear to be stable. Proper blending of reclaimed areas with undisturbed slopes was achieved, with the exception of one noted location where a scraper road at the crest of a graded slope was not properly eliminated. Reconstructed drainages within the original permit area are stabilizing and in good condition, with only a few exceptions noted where further work is required (Channel 006-NE2 and 006 Gulch). Minor hillslope erosion and minor channel erosion was noted, but the extent and nature of the erosion observed this minor erosion is considered a maintenance item to be addressed in the context of the Annual Rill and Gully Plan. The Division finds that Seneca has achieved the requirements for Phase I bond release for 721.9 acres at the Seneca II-W Mine. 17
