The Tie - Across Haul Road (TAHR) was designed and constructed during 1989 in preparation for coal haulage in 1990 from the Seneca II -W Mine area to the Hayden Station Power Plant. The TAHR was originally approved as part of the Seneca II -W Permit No. C- 1982 -057 and was transferred to Hayden Gulch as part of PR -01 (approved January 2012). Once again the reclamation bond was increased to include the TAHR. In 2011 HGL reclaimed the proposed loading/unloading facility area. The reclamation activities included removal of all tipple and coal handling structures, elimination of the remains of surface coal piles, and reconfiguring the area (including finish grading, topsoil replacement and seeding of 11.9 acres). Following the reclamation activities, HGL applied for Phase I bond release on the 11.9 acres. HGL filed an application (SL -1) for Phase I bond release on February 2, 2012 requesting release of $488,408 on 11.9 acres. On July 27, 2012, the Division approved the release of $353,829.24 on the 11.9 acres of reclamation. Exhibit 12 -1, Hayden Gulch, Tie - Across Haulroad Facilities, shows the current configuration of the HGL permit area following the SL -1 bond release. Permit Renewal RN -3 expires on May 22, 2013 and HGT submitted an application (RN -4) to extend the permit for another five years. The future operations /reclamation plans for the Hayden Gulch Loadout permit area during the next five year permit term will be based on future economic and political conditions. No future operational or reclamation scheduling can be developed at this time. PERMIT RENEWAL (RN -4) EXISTING STATUS /CONDITIONS This section updates the current status and condition of the HGT permit area facilities at the time of permit renewal (RN -4). Sediment and Water Control Facilities Plan There are two sedimentation ponds located within the permit boundary. The ponds were originally designed and constructed by Morrison - Knudson Company in May 1980 for the previous operator / permittee, H -G Coal Company. The ponds have been referred to as "Truck Loop Pond 1 (Pond A, Outfall 006)" and "Rail Loop Pond 2 (Pond B, Outfall 007) ". HGT identifies the ponds as "Truck Loop Pond" and "Rail Loop Pond" — the ponds are permitted by the Colorado Water Quality Control Division as industrial wastewater treatment facilities under Permit No. COG - 850008. Exhibit 12 -2 shows locations and contributing drainage areas for both ponds. The Rail Loop Pond was modified in 1985. A permit revision was submitted (by previous operator /permittee) to replace the culvert spillway with a trapezoidal spillway constructed of fabriform. Certification reports for this pond modification are presented in Appendix 12 -1A, Pond Certifications. The Truck Loop Pond was modified by the previous operator /owner in June 1992. This modification was performed to meet CDRMS regulations regarding separate pipe spillways. TR -10 2 Revised 02/13
