into the electrical distribution system. Circuit breakers, lightning protectors, and ample switching <br />~~ points with the necessary transformers have been built into each substation. Branchlines that lead <br />out to various loads aze protected with breakers to prevent trip out of the main breaker and <br />shutdown of the entire operation if a fault occurs on a branch line: The protective breakers on the <br />branch lines aze coordinated with the exception that the mine fans aze to be connected to the main <br />distribution line ahead of other breakers. <br />A pager-type mine telephone system connects all working sections to the mine office. The system <br />uses the same surface comdors as the power distribution system where possible. It also has backup <br />battery powered pagers. <br />Because the mine site is steeply sloped, benches have been or will be constructed and several azeas <br />have been designated for the storage of materials and equipment. An access road loop will be <br />constructed to create an approximately 3 2/3-acre storage bench located east of the office building <br />employee pazking lot. An approximately 1/3-acre bench, refened~to as the surface laydown area, <br />was constructed between sediment pond MB-1 and the fresh water pone. The upper and lower <br />portal benches and the old Beaz Mine site aze also designated for the storage of materials and <br />equipment. Other azeas, including neaz the warehouse, maintenance shop, surface shop, materials <br />. storage bench building, water treatment plant and along mine site roadways, and the surface of the <br />~ Lower Refuse Pile may also be utilized as needed for materials and equipment storage. <br />Employee and visitor pazking facilities aze provided on the bench above the office/bathhouse <br />building. Because the azea available for pazking is limited, Mountain Coal Company encourages <br />employees to use a pazk-and-ride system and car-pool. Pazking facilities are designed to use the <br />available space as efficiently as possible. <br />MCC has constructed a weather station located north of the intersection of the main mine <br />hauVaccess road and the middle hauUaccess road. The weather station consists of a set of sensors <br />mounted on a ten meter tower, and a precipitation gauge with a wind screen mounted neaz the <br />ground. The weather station collects "real-time measurements" on a regulaz interval for wind <br />speed, wind direction, air temperahue, relative humidity, precipitation, and barometric pressure. <br />i. <br />2.03-23 November 2004 PR1I <br />
