into the electrical distribution system. Circuit breakers, lightning protectors, and ample switching points with the necessary transformers have been built into each substation. Branchlines that lead out to various loads aze protected with breakers to prevent trip out of the main breaker and shutdown of the entire operation if a fault occurs on a branch line. The protective breakers on the branch lines are coordinated with the exception that the mine fans aze to be connected to the main distribution line ahead of other breakers. A pager-type mine telephone system connects all working sections to the mine office. The system uses the same surface corridors as the power distribution system where possible. It also has backup battery powered pagers. Because the mine site is steeply sloped, benches have been or will be constructed and several azeas have been designated for the storage of materials and equipment. An access road loop will be constructed to create an approximately 3 2/3-acre storage bench located east of the office building employee pazking lot. An approximately 1/3-acre bench, referred to as the surface laydown azea, was constructed between sediment pond MB-1 and the fresh water pone. The upper and lower portal benches and the old Beaz Mine site aze also designated for the storage of materials and equipment. Other azeas, including neaz the wazehouse, maintenance shop, surface shop, materials storage bench building, water treatment plant and along mine site roadways, and the surface of the Lower Refuse Pile may also be utilized as needed for materials and equipment storage. Employee and visitor parking facilities aze provided on the bench above the office/bathhouse building. Because the azea available for parking is limited, Mountain Coal Company encourages employees to use a pazk-and-ride system and caz-pool. Parking facilities aze designed to use the available space as efficiently as possible. MCC has constructed a weather station located north of the intersection of the main mine haul/access road and the middle haul/access road The weather station consists of a set of sensors mounted on a ten meter tower, and a precipitation gauge with a wind screen mounted neat the ground. The weather station collects "real-time measurements" on a regular interval for wind speed, wind direction, air temperature, relative humidity, precipitation, and bazometric pressure. 2.05-23 Revised Jan 1996 RN03; Revised Nov. 1996 PR07; Revised Jan. 1997 TR79; Revised Jul. 1997 TR82 Revised Oct. 7998 TR86; Revised Jun 1999 TR90
