The reconstructed[Elk Creek] channel was removed from the SL-I parcels at the Division's request so as to allow time for the stability of the channel to be assessed. The channel will be observed regularly throughout the ongoing period of reclamation liability. When the long-term stability of the entire channel has been demonstrated, an update to the PAP to include as-built details of the reconstructed channel prior to an application for Phase I, II and III bond release will be required. (1) De-gasification Wells, Fire Control and Monitoring Borehole Sites (Page 2.05-67) The vast majority of boreholes constructed at the site have been plugged and abandoned, and their pads and access roads have been reclaimed. The Division understands that only those boreholes still being used to monitor groundwater remain to be reclaimed. All of the reclaimed boreholes, pads and roads have received at least Phase 11 bond release with SL-2, -3, -5, -7 and -8. For boreholes which remain open to be eligible to receive bond release, it will first be necessary to terminate the groundwater monitoring program, and then properly plug and abandon them and reclaim any associated surface disturbance. The Surface and Groundwater Monitoring Liability Period is discussed in Rule 4.05.13(3). Any modification of the water monitoring program will require a Technical Revision, with supporting data and analysis. Before water monitoring is terminated, the rule requires demonstration: ...that these qualities and quantities of runoff without treatment are consistent with the requirements of 4.05; that the operation has minimized disturbance to the hydrologic balance in the permit and adjacent areas; that the operation has prevented material damage to the hydrologic balance outside the permit area; and that the water rights of other users have been protected or replaced. 18
