• Other seams present within the area are the Palisade and the Carbonera. Both are of limited economic interest. These seams tend to be thin, lenticular and of poor quality. Additional information regarding the geology of the mine permit area can be found in Volume 2, Tab 6 of the mine permit application. Mine Production and Design During 2000, no coal was produced from either the Roadside North or South Portals. The area where mining occurred during 1999 is shown on Figure 1, 2000 Annual Subsidence Survey. The overburden in the areas mined at Roadside North Portal Mine ranges from approximately 1,800 feet to approximately 300 feet. Extraction ratios vary from 43% for a 60 foot by 120 foot entry spacing to 68% where second mining occurs. Projected Mining for 2001 None • Surface Inspection Stipulation 12 of the mining permit application requires that surface inspections (pedestrian surveys) of the mining area be conducted in the spring and fall of each year. The 2000 inspections were conducted on May 30, 2000 and December 4, 2000. The areas inspected during the survey are shown on Figure 1, Roadside North Portal, 2000 Annual Subsidence Survey. No subsidence related features were noted during the pedestrian surveys. There are no reports of subsidence or subsidence related problems from any adjacent landowner or utility company. Although high cover minimizes the expression of subsidence features on the ground surface, no subsidence features were noted in the area above the Roadside North Portal Mine. The route traversed was directly over the area where the 2 West Panel was second mined. Particular attention was given to those areas in the topography where slumps or cracks would be more apparent, such as ridge lines. The attached photographic review of Jerry Creek Canyon depicts the canyon itself, the • steep nature of the canyon walls and the dry, ephemeral stream channel of Jerry Creek. 2000 Subsidence Report Page 2
