Both <br />at Colorado Yampa ;,_~~ <br />~ , <br />~~t ~~~ <br />minor revision ~Gb'A• ~, ~~~ <br />modifications wilt~~~° `~V~ <br />~ ~`~~ ~~ C^ti~ <br />The two changes involve relocating the electrical substation an8~ `>`• <br />installing a stoker oiling system. The location of these facilities are 'a ' `~ <br />shown on the enclosed Figure, MR 87-21-1: Operation Modifications at the.,` `\ <br />Tipple Area. <br />At the substation site, a concrete slab measuring 6 X 12 X 1 feet will ~e~ ` <br />be constructed. The transformer will be located on the concrete slab. ~,~ ~„ <br />Three H-frames will support lightning arrestors and fuses for the 69,000 ~ ~~ <br />volt (69KV) and 4160 volt lines. A fence measuring "c5 X 50 feet will~t~~ o- ~~ <br />surround the substation. The schematic for the substation is shown or~~ ~\ y <br />Figure MR 87-21-2, Substation Plan View. ~{•~ )i-~~s <br />Colorado Yampa Coal Company plans to construct the stoker oiling systern ~`~ ? ~ ~~ <br />within the tipple area as well. The heated oil will be piped along the s <br />product belt structure and will be applied to the stoker coal as the coal ~ ,~~;'` i <br />leaves the belt. A 500 gallon oil heating tank will be located immediately <br />adjacent to the secondary crusher as shown on Figure MR 87-21-1, Operation ~~ `~` <br />Modifications at the Tipple Area. A 12,000 gallon storage tank will be ` ~'c°`~\5`~~, <br />located south-west of the crusher building. Both tanks will be surrounded ~~ , .~~ <br />with appropriate SPCC structures. The 500 gallon tank will be surrounded bye` a~ ~.4` <br />a 3.5 foot berm with outside dimensions of 68 X 21 feet. Concrete pad and ~ ~~ ~ ~ <br />walls will surround the 12,000 gallon tank. The dimensions of the slab wil~' cs. ~~ <br />be 6 X 9 feet and the walls will be 2.5 feet high. ~~,~~ " <br />As you know, a sedimentation system already exists around the tippleS~~ ~^! ~ ~~ \ <br />All construction will take place in the previously disturbed areas. ~` ~ ~, <br />`~ C <br />
