This project, known as the Huntsman Project, will stabilize the <br /> north facing slope of the refuse pile_ <br /> As you may be aware,a portion of the north facing slope of the Old Refuse Pile located adjacent <br /> to the 001 pond inlet ditch is extremely over steepened,and as a result has suffered some degree <br /> of movement towards Coal Creek. The Division's field observations indicate that a potential <br /> exists for continued movement in the future. A large scale or deep seated failure would negatively <br /> impact Coal Creek. The Division believes it is necessary to take measures to decrease the <br /> potential for a failure to occur. <br /> The proposed project area is located south of, and generally adjacent to Coal Creek,east of the <br /> Dutch Creek Flume, north of the power line which traveuses the crest of the Old Refuse;Pile;, and <br /> west of the 001 ponds. The permit document submitted by Mid-Continent Resources at Map 11- <br /> B-7 indicates that this north facing slope was constructed prior to enactment of the Surface <br /> Mining Control and Reclamation Act of 1977. Field observations indicate that this area has not <br /> been affected by mining operations since that time. Thus, the;site has been deemed to be eligible <br /> for remediation with Federal monies made available through the Abandoned Mined Lands <br /> Program. <br /> The scope of the project is to create a less steep slope configuration by removing a portion of the <br /> refuse, placing topsoil materials over the cut slope, and revegetating the area. Care will be taken <br /> to minimize sediment delivery to the 001 pond system through use of sediment control devices <br /> adjacent to the 001 pond inlet ditch. <br /> Although final volumes have not been finalized, it is cstimatud that bct\vecn 20,000 and 30,000 <br />
