-lo- <br />• <br />III. Cultural and Historic Resources (cont'd <br />Underground coal mining operations in and adjacent to the lease areas began in <br />1899 and have run continuously to the present. According to the current mining <br />plan, no additional surface lands will be affected during the life of the permit. <br />A11 coal will be mined through the existing surface facilities of the Roadside <br />and Cameo Mines. There is a possibility, however, for the occurrence of subsidence <br />in areas where underground mining will take place. <br />Several cultural resource inventories have been conducted within the lease areas. <br />They include: "An Archaeological Clearance of BLM Lands for the Cambridge Mining <br />Company"(Conner 1975); "Antiquities Inventory for Cambridge Mining Company: Coal <br />Mine Portal and Area for Coal Mine Debris Disposed in Coal Canyon and Coal Gulch, <br />Cameo, Colorado" (WignaZZ and Conner 1977); and portions of an inventory entitled <br />"Final Report of an Archaeological Survey of the West Central Colorado Coal <br />Leases" (Nibbets et a1 1979). All total, over Z0~ of the lands in the lease <br />areas have been inventoried for cultural resources at a class III level. <br />No sites were identified in the areas inventoried by Conner and Wignall and Conner. <br />A total of 28 sites and 3B isolated finds were identified by Nibbets in coal <br />leases C-029889 and C-024998. <br />According to the mine plan submitted by Powderhorn Coal Company, there will be no <br />direct surface disturbance within the lease areas. A11 proposed activity will be <br />in the form of underground coal mining operations. Therefore, there will be no <br />direct adverse impacts on any sites that are eligible for listing on the National <br />Register of Historic places within the lease areas. <br />There is a potential for some indirect impsct to occur to sites eligible for <br />listing on the National Register from subsidence in areas where underground mining <br />will take place. <br />Because it is not possible to determine with any certainty the exact extent to <br />which, or location where, subsidence may occur, the following requirements will <br />be stipulated as a result of the BLM's mine plan review in the decision package <br />issued by the Office of Surface Mining. <br />Since the proposed operation will not affect any sites listed on the National <br />Register of Historic Places, the proposed operation is in compliance with the <br />requirements of this section. <br />
