C1981012: TR68 SECTION 3.0 REVIEW <br />Rio Blanco County - Rangely: 10.03 inche <br />Weld -Ft. Lupton: 12.63 inches <br />Mesa County- Fruita: 9.25 inches <br />Palisade: 9.88 inches <br />Montrose County - Uravan: 12.54 inches <br />Norwood: 15.41 inches <br />Routt County- Hayden 15.45 inches <br />JANUARY 22, 2014 <br />s Deserado: 50% failure rate rangeland <br />Keenesburg: 60% failure rate rangeland <br />Fruita Loadout: 50% failure rate rangeland <br />Roadside: 50% failure rate rangeland <br />New Horizon 25% failure rate rangeland <br />10% failure rate irrigated pasture <br />Foidel Creek: 20% rangeland <br />NECC has not provided valid supporting data or written recommendation by federal, state, or local <br />agencies that would support reducing the revegetation failure rate to a value less than 33 %. The <br />Division will continue to use a 33% failure rate in the RCE vegetation tasks. <br />If NECC believes that areas at the New Elk mine that have previously been seeded with the permanent <br />seed mix are eligible for bond release, NECC should submit a bond release application to the Division <br />for these areas. <br />• In Section 3.0, page 5, NECC states reasons substantiating why disc harrowing is not needed for <br />reclamation tasks. The Division concurs and will not include disc harrowing in the RCE revegetation <br />tasks. <br />• In Section 3.0, page 5, NECC provided additional detail regarding specific RCE tasks. <br />• The corrected East Portal Hoist House dimensions will be used to update the Demolition task. <br />• NECC provided an argument against using a drill rig to abandon shallow alluvial wells. The <br />Division concurs with this argument and will revise the sealing task for the shallow alluvial well <br />to remove the drill rig from the task. Sealing of deep well will still necessitate using a drill rig. <br />• NECC provided updated dimensions of the three Bates portal openings, the West Portal. The <br />updated dimensions will be used in the Division's RCE portal sealing and backfilling <br />calculations. <br />• NECC contends that the West Portal abandonment will not require construction of a bulkhead <br />seal in accordance with Rule 4.07.31 and consistent with 30CFR 75.1711? Did the West Portal <br />sealing methodology met MSHA requirements? <br />3 <br />
