2014—2016, the production averaged 236,565 tons per year. NHN notified the Division on June <br /> 8, 2017 that coal extraction had ceased. The active pit was backfilled and graded in 2018. Coal <br /> was transported to the plant by contracted haulage trucks over a network of Montrose County <br /> roads. The Nucla Station ceased operation in 2019, and was demolished in 2022. <br /> Reclamation Plan <br /> Reclamation activities occurred concurrently with mining. The backfill and grading timeline is <br /> outlined in Table 2.05.4(2)(a)-1 of the permit. A typical diagram illustrating the mining and <br /> backfill process is provided in Map 2.05.3-1 of the permit. Following backfilling and grading, <br /> topsoil is redistributed to the thicknesses shown on Map 2.05.4(2)(d)-1. The type and thickness <br /> of topsoil is related to the post-mining land use. Replaced soils are prepared for seeding as <br /> described in Sections 2.05.4(2)(d) and (e) of the permit. The reclaimed lands will be capable of <br /> supporting the same uses that were present prior to disturbance. <br /> Water rights and usage <br /> ERMR owns several water rights which are detailed in Table 1 of Appendix 2.05.6(3)-lb of the <br /> permit. The water will be used for irrigation, industrial and storage. The approved water <br /> augmentation plan is in Appendix 2.05.6(3)-1c of the permit. <br /> All the wells within a 1-mile radius of NHN permit area are listed on Table 2.04.7-4 in <br /> Section 2.04.7 of the permit.
