TC is requesting the approval to add a pre-fabricated <br /> 10'x20' Master Control Center (MCC) building along with adding an addition to the existing pump enclosure <br /> building to allow for an additional pump and controls for the recently approved larger second pipeline. The <br /> MCC building will be a pre-fabricated building that will be placed on a 1 foot thick concrete slab. The addition <br /> to the existing pump enclosure will extend the current building to the west with an 18' X 32' addition to enclose <br /> the additional pump system needed to pump the thickener slurry of the recently approved larger diameter <br /> pipeline that parallels the original pipeline. With the upgraded pump system an MCC building was necessary to <br /> insure proper controls and necessary monitoring for the larger pipeline. An additional transformer is needed to <br /> run the additional pump and will be installed on the south side of the building next to the existing transformer on <br /> an 8' X 8' concrete pad. <br /> This submittal includes a revision application form, revised PAP text addressing the 2SW Booster Pump <br /> Upgrades, a revised Map 24 showing the additions to the 2SW Pump Station, and a bond estimate. We would <br /> like to proceed with this project as soon as possible. We, therefore, appreciate your consideration, cooperation, <br /> and assistance in facilitating timely review and approval of this revision application. After you have opportunity <br /> to review the accompanying information, please feel free to contact me with any questions or to discuss <br /> submittal materials or related matters. <br /> Sincerely, <br /> Twentymile Coal, LLC <br /> ka'4x� <br /> Miranda Kawcak <br /> Environmental Engineer <br />
