October 5,2010 C-1981-008/New Horizon Mine MLT SUPPORT FACILITIES -Rule 4.04 • We inspected the support facilities area on foot. The yard area south of the office buildings is used to store various items of equipment, including new and used wheels and tires for the mine's haul truck fleet. Two sets of 5-gallon tubs were stored on pallets, in the open. WFC personnel informed us that the contents were Bentonite pellets and vegetable oil lubricant, both of which are non- petroleum products. • The fuel depot is surrounded on all four sides by a berm which provides secondary containment. The bottom of the enclosure and the inward-facing sides of the berm are lined with an impermeable membrane. A layer of gravel is spread on top of the membrane across the bottom surface of the enclosure. • Filling of the diesel and gasoline tanks is accomplished when a tanker truck pulls up alongside the north side of the bermed facility. A hose is connected to the tanker and the storage tank, and fuel is off-loaded. The gravel beneath the storage tanks was stained with fuel, indicating that some spillage does occur during the process of filling (Photo 7). However, no staining was observed on the ground surface outside the bermed area. • We observed several small (<I" diameter) holes in the membrane on the inward-facing slope of the berm, adjacent to the tank-filling area, and postulated that these may be caused by the wear and tear of the tanker truck driver stepping over the berm to connect the hoses, or by hoses dragging across the membrane. Mr. Fry stated that he would look into getting the holes in the membrane patched. • Petroleum products are also stored in a 3-sided shed in the facilities area (Photo 8). Individual containers are labeled, and it appears that secondary containment has been provided. The mine uses oil reclaimed from vehicle maintenance operations to heat the heavy equipment shop. The tanks holding the used oil are set within a concrete enclosure. SPECIAL CATEGORIES OF MINING—Rules 4.22 through 4.27 (Prime Farmland—Rule 4.25) • Upon our arrival, we were informed that the Morgans had commenced irrigation of the undisturbed field that lies immediately ahead of the mining operations. Because WFC intends to salvage topsoil from a portion of this field later this fall, and the soil must not be saturated for the operation, they were attempting to contact the Morgans to have the water turned off. • There were no active topsoil salvage, Bench 1 removal, or backfilling operations occurring at the time of the inspection. • Two Bench 1 stockpiles have been established on the Morgan prime farmland property. Lift A and Lift B topsoil stockpiles are posted with identifying signs. Ditches have been cut around the bases of the topsoil stockpiles (Photo 9) in order to protect the resource from loss due to erosion. TOPSOIL—Rule 4.06 Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution 4.06.4 • On the Lloyd property, topsoil was distributed over additional acreage during 2010. The soil had been disked for seeding, but not yet rock-picked(Photo 10). A temporary crop will be planted for the winter.
