accurately reflect the currently approved mining plan 13. Attachment 12-3 includes a narrative description and location map (Figwe 49-1) regarding Sage Creek and Wolf Creek coal seam, overbwden, and underbwden ground water monitoring wells. The wells were damaged by apparent ground movement m the spring of 2003, and will need to be replaced. Please Amend Attachment 12-3 to address the current status of the subject wells, and include a commitment to install appropriate replacement monitoring wells in 2004. Rnle 7 nS'i(3~(r) Roadc 14. Narrative on Tab 13, page 11 references As-Built designs for various haul roads. The narrative needs to be updated to reference the Haul Road J As-Built. Also, Haul Road K construction has been completed, but the required construction certification has not yet been submitted. The required certification and As-Built for Road K will need to be provided. Please submit required Haul Road K construction certification and As-Built design, and amend narrative as appropriate to reference Haul Road Jand K As-Built designs. l5. There is out-dated regulatory language on page 16 indicating that haul roads not within the distwbed area will be certified "if requved by the DMG for good cause shown". Please delete the quoted clause, to correspond to the current haul road certification requirement of 4.03.1(1)(d)(i). 16. Narrative at the bottom of page 27a of Tab 13, regarding haul roads to be retained as permanent access roads, does not "flow" to page 28. Itemized provisions "c" through "e" seem to be missing. Please amend the referenced pages as appropriate. 17. Access Road narrative beginning on page 28 of Tab 13 is outdated in several respects. First, the narrative should be amended to address the proposed oil well access road. Second, current Rules 4.03.2(4)(1) and (ii) require certification (or statement in lieu of certification in certain cvcumstances) for access roads not within [he disturbed area. Third, embanlanent slope minimum safety factor of 1.25 does not comply with current 4.03.2(3)(e)(ix) requirement of l3. Finally, the citation at the end of the last full paragraph on page 31 does not correspond to the rule section as currently organized. The appropriate citation would appear to be 4.03.2(3)(e)(iv). Please amend the narrative section as appropriate. Rnle'7 OS i(4) Pnnd~jmpnnndment y Other Trratmrnt Farilitiec and tlivrrcinnc 18. Construction certification and As-Built design for recently completed Sediment Pond 016A has not yet been submitted. Construction certification and As-Built design for Sediment Pond 006 Phase V design (incorporating recently installed primary spillway extension) has not yet been submitted. Initial annual impoundment certifications for Sediment Ponds 005, 006, 009, 015, 016, and 017 have not yet been submitted. Please submit the referenced construction certifications/As-built designs and annual impoundment certifications, as necessary to comply with applicable requirements of 4.05.9(14) and (15). 19. In the November 2003 inspection report, the need was identified for a new collection ditch to diver[ disturbed area runoff from the active pit, spoil, and pre-strip areas away from the native drainage channeUriparian zone of Hubberson Gulch fork above Pond ] 7. The operator indicated that a revision would be submitted to address construction of such ditch along the existing light use road above Pond 17. Disturbed drainage would be routed along the ditch directly into Pond 17, to protect the native channel segment from excessive erosion or sediment deposition. Please submit appropriate design plans for the referenced collection ditch. 20. Text on page 4 of Tab 13 states that the sediment storage capacity of each sedimentation pond or imoandment will be monitored on an annual basis to ensure at least one year of sediment storage beneath the principal spillway. The sediment storage capacity is critical for sedimentation ponds and other sediment retention 13
