- Grease Pit: a concrete subgrade grease pit exists between the West Shop and the East <br />shop; this pit was covered in November 2002. The site map will be revised in the <br />future to show the closure of the grease pit. All areas of oily soil around the shop and <br />grease pit area were aerated several times over recent years, and oily spots were again <br />aerated in November 2002. Remediation of oil-stained soil by aeration is showing <br />excellent results. Barrels of used engine oil were removed from the north side of the <br />West shop in January 2002; the oily soil where these barrels sat was also aerated in <br />November 2002. <br />- East Shop: 35' x 13' concrete pad on west side of building, 41' x 35' shop building <br />with tank stands and a 12' x 26' attached storage area and a 12' x 12' attached storage <br />area. This building is in poor repair and has generally only been used for materials <br />storage. <br />- Office and Dry building: 50' x 36' with 4' sidewalk on two sides. Building has been <br />vandalized, but is stable. <br />- Small Items Warehouse: 28' x 12' building adjacent to Office. Old building in quite <br />poor condition. <br />- Compressor building: 20' x 16' building that has had door removed to remove <br />compressor and is now open to the elements. <br />- Compressor building: 20' x 40' old building with two old compressors still inside. <br />Building in poor condition and has been extensively damaged and is open to the <br />elements. <br />The powerline into the Sunday Mine site belongs to the Operator. There is some <br />confusion on exactly where the Operator's line begins and connects to San Miguel Power's <br />service. Plans are underway to meet with San Miguel Power personnel to identify and map <br />ownership of electrical service structures at the Sunday Mine and all related facilities. <br />An electric power transformer station is located east of the compressor buildings. Nine <br />transformers are included in a fenced and locked enclosure. The transformers and the platform <br />are stable and secure. Six of the transformers are tagged with light blue "PCB-free" stickers and <br />belong to the Operator. Three transformers are not tagged and these are the property of San <br />Miguel Power; ownership of these three units will be verified. <br />A "boneyard" area exists to the west of the warehouse/wash bay. Various old pieces of <br />equipment and materials are located here. The site is stable and the Operator is selling or <br />otherwise using equipment from this area as opportunities arise. <br />Two horizontal fuel storage tanks are located east of the shops on the edge of the east <br />waste dump. One tank is 8' diameter and 28'4" long and the other tank is 9'7" diameter and 15' <br />long. Both tanks are empty. The Operator is aware that these cannot be used in the future <br />without providing spill containment. <br />A truck scale is located in the center of the mine yard, near an ore dump and loadout <br />station. A small diameter vent pipe with a riser with a fan on it is located in the center of the <br />yard in the slope of an interior waste dump. This small diameter vent hole is stable with no <br />evidence of caving or sloughing. Vent Hole S-2 is located at the south center edge of the mine <br />yard, but it is included in the Disturbed Area associated with the Roads and Vent Holes (Figure <br />2). <br />5 <br />
