Susan Burgmaier -3- November 24, 2014 <br />a. Topsoil pile A is labeled on Map 15 -3 (sheet 1 of 4) which is consistent with the text on <br />pages 2.05 -50 thru 2.05 -53. The four topsoil stock piles shown On Map 15 -3 (sheet 3 of 4) <br />have different labels than the descriptions and volume charts in the text. Please update the <br />topsoil pile names on Map 15 -3 (sheet 3 of 4) to be consistent with the text and volume <br />charts. <br />BRL - Updated on TR -91 Map 15. <br />b. The text on page 2.05 -66 states that topsoil pile A contains 111,900 CY and will be spread <br />over 64 acres. The chart and text on page 2.05 -52 shows that 154,900 CY of topsoil have been <br />salvaged in topsoil pile A. Please correct the discrepancy in the values or explain what the <br />plan is for the remaining 43,000 CY in topsoil pile A. <br />BRL - Please see revised page 2.05 -66. <br />c. The text on page 2.05 -66 states that topsoil piles D & E contain 42,472 of topsoil and will be <br />spread over 48.9 acres. The chart on page 2.05 -52 shows that only 6,100 CY have been <br />salvaged. Please verify the quantities of topsoil salvaged, storage location and quantity <br />needed to provide an adequate depth of topsoil to establish a sustainable vegetative cover. <br />BRL - Please see revised pages 2.05 -52 & 2.05 -66. <br />d. The text on page 2.05 -66 states that "topsoil stockpile F will contain 24,000 CY. It will be <br />spread over the 22 acres of the reclaimed unit train loadout to a depth of approximately 1.2 <br />feet." The volume of topsoil required to cover 22 acres at a depth of 1.2 feet is 42,592 CY, but <br />only 24,000 CY are in the stockpile. This is a difference of 18,592 CY. Please clarify the area to <br />be topsoiled, the topsoil depth, stockpile volume and any additional topsoil source that may <br />be used <br />BRL - Please see revised page 2.05 -66 and 67. Text was updated in regard to topsoil <br />replacement depth, and to be consistent with text in Volume IX. <br />10. The text on currently approved page 2.05 -62 includes a discussion of projected refuse <br />production, and estimates that annual refuse production will be about 200,000 tons per year. <br />The current rate of refuse production is about 211,000 tons per quarter; 2014 production to <br />date is about 250,000 tons per quarter. Please update the discussion on refuse generation on <br />page 2.05 -62 to reflect current conditions. <br />BRL - Refuse generation was updated on page 2.05 -62. <br />11. Please update page 2.05 -62, the references to design information for the gob piles, to <br />include Gob Piles #3 and #4. <br />
