<br />Facilities necessary to house additional personnel for E Seam construction and development <br />work aze planned to be installed neaz Shaft #1 in Sylvester Gulch in late April and be completed <br />in late May 2005. These facilities will be temporary in nature and designed to be removed when <br />additional staffing is no longer required for E Seam development and construction needs. <br />All construction and installation work will be performed within the existing disturbed azeas at the <br />Shafts #1 and #2 azea in Sylvester Gulch. There aze no plans to change any existing sediment <br />controls, ditches or roads. Surfaces will be restored to the existing compacted roadbase when <br />excavations for conduits and piping aze completed. <br />All equipment and facilities will be placed on the existing surfaces with no concrete foundations <br />anticipated except for the two electrical transformers required for the facility. These will require <br />a single reinforced concrete slab on grade expected to be approximately 8 feet wide by 12 feet <br />long. This slab will also be removed when additional staffing is no longer required. <br />Potable water will be supplied using a 10,000 gallon surface tank and pressure pump system. <br />This tank will be supplied with potable water from WEM's existing potable water treatment and <br />storage system via truck haul to Sylvester Gulch. <br />Waste water from the facilities will be stored in a plastic buried septic (closed) tank with an <br />• approximate capacity of 10,000 gallons. This tank will be periodically pumped and the waste <br />water hauled to WEM's existing waste water treatment facility as needed. <br />Four modulaz bath/changing units and one modulaz office unit will be placed at the site west of <br />Shaft #1 on the same level as shown on MCC drawing S52SG005 and Map 54. Electrical <br />distribution panels for the facilities will be housed in a skid mounted steel enclosure. Water <br />supply equipment will be housed in a second skid mounted steel enclosure. Electrical service <br />will generally be supplied via conductors within buried conduits. Potable water piping and waste <br />water piping will be a combination of buried and surface piping. <br />Construction of the service infrastructure is expected to occur in late April and eazly May 2005. <br />Completion of construction and installation of the modular units is expected to occur in mid to <br />late May 2005 when the modulaz units aze expected to be delivered. The facilities need to be <br />placed in service no later than the last week of May 2005 to meet WEM's needs for housing <br />additional construction and development staffing. <br />• <br />13A Exhibit 69, MR-305, May 2005 <br />
