As you may recall, Shaft No. 3 is <br />approximately 100 yards east of the existing degas borehole facility. The purpose of the building is to <br />provide cover for up to three blower units that will be attached to HDPE methane drainage pipelines <br />installed in Shafr No. 3. <br />The steel building will require the construction of a concrete pad (slab on grade with thickened edges, <br />40' x 22') and 3 smaller pads (approximately 6' x l0') for aprons or approaches for doorways. The <br />pads will be 6"thick and reinforced with rebar. The building will be added to Map 53B and 54B. <br />MCC requests the Division's assistance in calculating the bond estimate for this structure. <br />Please notify me if you have questions regarding this minor revision request. <br />Si , <br />d. 7~ <br />eery A. be <br />Environmental Engineer <br />cc: E.
