-4- <br />The following time-table provides our best estimate of the <br />phased activity: <br />Phase 1: Identified as Area A <br />-Mining completed in 1985. <br />-Embankments regraded, topsoil distributed, and seeded to <br />grass in 1982-83 and 1984-85, except as noted. <br />-Terrace floor backfilled and graded to 0.5% slope, topsoil <br />distributed, and seeded to &rass in 1992-93, except as <br />noted (re: beltway deletion). <br />-Irrigated as needed 1983-94. <br />Phase 2: Identified as Area B <br />-Mining preparation started in 1984-85. <br />-Mining completed in about 1987. <br />-North embankment above pipeline, and possibly a portion <br />of the terrace floor, not required for mining, backfilled <br />and regraded, topsoil distributed, and reseeded in 1987-88. <br />-Terrace floor backfilled and graded to 0.5% slope, topsoil <br />distributed, and seeded to grass in 1992-93, except as <br />noted ( also beltway concept). <br />-Irrigated as needed 1987-94. <br />Phase 3: Identified as Area C <br />-Mining preparation started in 1987. <br />-Mining completed in 1992-93. <br />-Southwest embankment and possibly a portion of the ter- <br />race floor below the embankment backfilled with over- <br />burden and regraded 1990-92. <br />-Balance of terrace floor backfilled with over-burden in <br />storage and as needed from the north boundary of the <br />storage area embankment in order to assure a finished <br />grade of 0.5% across the entire terrace floor 1992-93. <br />-One-half of topsoil (or as needed) in storage area to be <br />distributed on the balance of all emba::kments and the <br />entire terrace floor, except as noted, and seeded to grass <br />in 1992-93. <br />-Irrigated as needed 1992-94. <br />Storase Area <br />-A portion of the topsoil transfered from the north side <br />to a final graded area on the terrace floor 1992-93. <br />-Approximately 44,000 cu/yds removed for backfill on the <br />terrace floor leaving the exposed embankment graded to <br />a 3:1 slope, topsoil replaced and seeded 1992-93. <br />-Balance of topsoil stockpile distributed around housing <br />and commons area after construction 1994. <br />- Irrigated as needed 1992-94, <br />
