Following the review process for the initial permanent program permit application, the Division issued a permit with stipulations on January 3, 1983. On November 9, 1984, Powderhorn Coal Company submitted plans for a perrnil revision to construct two new coal processing waste embankments to be located north (CRDA-2) and west (CRDA-3) of the existing Cameo Refuse Disposal Area (CRDA-I ). This revision was approved on March 1 l,, 11985. I'' In October 1986, Powderhotn Coal Company notified the Division oftemporagccessation ofoperations at the Roadside and Cameo Mines. In eazly 1987, Peabody Holding Company (Peabody) purchased the inactive Roadside and Cameo Mines. Peabody retained the Powderhorn Coal Company name for the company. On April 20, 1989, Powderhgtn Coal Company (PCC) notified the Division of its ineent to emerge from temporary cessation status on May I, 1989. The mine was active from that date, until December, 1999, producing up to 70,000 tons of clean coal per month. Up until November 1994, production was limited to the Roadside South Portal, but at that time the North Portal was reactivated, and coal was produce from both portals until early 1997, when all coal production was shifted to the North Portal. Due primarily toicoal quality problems, mining ceased on December 2, 1999. By letter of December 13, 1999, the operator notified the Division that cessation ofoperations would extend beyond 30 days. A subsequent letter received by thi:' Division on March 14, 2000, provided official notice that the cessation ofoperations was permanent, pursuant to Rule 4.30. Current (July 2007) official status of the operation is "Active", due to approved use of the unit train loadout for material storage and loading, and due to periodically on-going reclamation activity. There are no plans for future coal extraction at the operation. The original permit has been granted renewal for successive five year permit terms three times, the most recent renewal decision was finalized October l7, 2003, for a permit term extending tlirough January 3, 2008. One stipulation (No. 22) was attached to the 2003 permit renewal (RN-04), and remains in effect. Several technical revisions (TR's) and minor revisions (MR's), were submitted and processed since the most recent mid-term permit review (August 2005). The stipulation and permitting actions are sumrriarized below. Status of Previous Stioulations One stipulation (Stipulation 22) was attached to the 2003 RN-04 renewal permit and proposed decision. Stipulation No. 22 requires specific documentation to be provided prior to initiation of mining within the subsidence angle of draw beneath the 345 KV Rifle-San Juan Powerline, within the South Portals mining area. Mining operations have ceased, and the portals have been sealed. As such, it is likely that the concerns addressed by the stipulation will not be realized. The stipulation is retained as a precautionary measure, in the unlikely event that operations would re-initiate in the future. Pennittin¢ Actions Processed Since August 2005 Mid-term Permit Review Technical Revisions TR-45 proposed approval decision was issued October 11, 2005. The revi~;ion allowed for reclamation schedule extension to allow operator time to finalize a pending property sale, amJ prepare a postmine land use change revision application. TR-46 proposed approval decision was issued December 13, 2005. The revi~;ion provided permit updates requested by the Division based on the mid-term permit review. Changes included revised reclamation Permit Revision No. 3 ~~ Permit No. C-1981-041 July 30, 2007 Page 4
