RN17-05 1-5 Revised 11/17 handle approximately 2,000,000 tons of coal per year. The unloading system approved by CDMG under TR-06 (June 2005) included the following components: • An unloading hopper to unload rail cars • A 60-inch reclaim conveyor, housed in an inclined concrete tunnel to transport coal (4,000 tph) from the unloading hopper to a rubber-tired radial stacker • The radial stacked will feed a 30-foot high, 30,000 ton coal stockpile • A tracked dozer will move the coal from the stockpile to the existing truck-dump hopper • The existing truck dump reclaim conveyor will move coal (1,500 tph) through the existing crusher building to a loadout conveyor (existing conveyor relocated) to the loadout building (re-locate and modify existing) As part of the approved plan the existing crusher building will be refurbished and the crusher will be removed and replaced by a coal chute. In addition, the loadout conveyor will be refurbished and relocated from the existing stack tube reclaim tunnel to the crusher building. The loadout conveyor will then be used to elevate coal from the crusher building to the top of the re-furbished and relocated loadout structure. Haulroad HGLF-HR2, which was previously permitted as part of the original C- 92-081 permit package, will be re-aligned and re-constructed as a dedicated haulroad. Consequently, the Hayden Gulch Loadout, in its current physical and regulatory state, is permitted as a dual-purpose facility. Under the original facility plan, approved by CDMG with the original C- 92-081 permit application package, and which is still part of the permit application package (see Attachment 12-1), HGTI is approved to loadout coal via railcar for shipment to market. The railcar unloading plan, which is permitted under TR-06, allows HGTI to change the operations at the facility if warranted by market conditions (e.g., if Routt County suddenly prohibited truck haulage from the Foidel Creek Mine to the Hayden Station over Routt County Road 27) to facilitate either railcar loading or unloading and loading of trucks from a stockpile. Tab 23 of the PAP presents the reclamation liability estimate. The liability estimate for TR-06 (the railcar unloading plan) is $1,083,800. HGTI calculated that the railcar loadout plan liability (original operation and the on-the-ground condition) at $916,090. Consequently, there are reclamation bonds in place for either operational alternative. Because of the inactivity at the facility and uncertainty with regards to the future use (i.e., railcar loadout, railcar load-in or both), HGTI reaffirmed with CDMG that the Hayden Gulch Loadout permit was in temporary cessation in correspondence dated August 30, 2005. With a corporate decision to not pursue development of the reserves to the south, HGTI initiated reclamation activites in 2011, removed the surface facilities associated with the coal handling operations, and backfilled and regraded the facilities area. On February 2, 2012 HGL submitted a partial Phase I Bond Release application for an 11.9 acre portion of the total 202.1 acre disturbed area where the loadout facilities were located. The decision to approve was issued on July 27, 2012 and reduced the reclamation bond liability to $1,203,940. The facility returned to temporary cessation status following the 2011 reclamation activities, and remained inactive until July of 2016, when HGTI initiated a second phase of reclamation, removing the rail, ties, and ballast from the rail spur. As a result on these ongoing activities, and in
