The Cameo Power Plant,which was a customer for coal from the Roadside Portals <br /> when the mine was operating, was located just south of the North Portal facilities, on the west side <br /> of the river.The Cameo Power Plant closed at the end of 2010 and has been completely demolished <br /> and reclaimed. The Cameo Power Plant area is part of the shooting range. <br /> Underground mining operations using modern, mechanized methods began in 1974. Between <br /> 1974 and 1999, approximately 242 acres of surface lands were disturbed in conjunction with the <br /> operation. GEX Colorado, Inc. submitted the original permanent program permit application for <br /> the Roadside and Cameo Mines on February 17, 1981, pursuant to Section 34-33-109 of the <br /> Colorado Surface Coal Mining Reclamation Act. On December 31, 1981, the Roadside and <br /> Cameo Mines were purchased by Powderhorn Coal Company (PCC). Following the review <br /> process for the initial permanent program permit application, the Division issued a permit with <br /> stipulations on January 3, 1983. <br /> On November 9, 1984, Powderhorn Coal Company submitted plans for a permit revision to <br /> construct two new coal processing waste embankments to be located north (CRDA-2) and west <br /> (CRDA-3) of the existing Cameo Refuse Disposal Area (CRDA-1). This revision was approved <br /> on March 11, 1985. <br /> In October 1986, Powderhorn Coal Company notified the Division of temporary cessation of <br /> operations at the Roadside and Cameo Mines. In early 1987, Peabody Holding Company <br /> (Peabody) purchased the inactive Roadside and Cameo Mines. Peabody retained the Powderhorn <br /> Coal Company name for the company. On April 20, 1989, Powderhorn Coal Company (PCC) <br /> notified the Division of its intent to emerge from temporary cessation status on May 1, 1989. The <br /> mine was active from that date, until December, 1999, producing up to 70,000 tons of clean coal <br /> per month. Up until November 1994, production was limited to the Roadside South Portal, but at <br /> that time the North Portal was reactivated, and coal was produced from both portals until early <br /> 1997, when all coal production was shifted to the North Portal. Due primarily to coal quality <br /> problems, mining ceased on December 2, 1999. By letter, on December 13, 1999, the operator <br /> 5 <br />
