Whitewater Building Materials Corp. WW 500 PIT <br />Permit # M-1977-129 2015 Annual Report <br />22 -September -2015 <br />Notes: <br />Please refer to Map 1 of 2 and Map 2 of 2 when reviewing the following <br />information. The effective date of all information is August 31, 2015. <br />8. An additional 16.26 acres was stripped in Stage 4 - Part A in the northwest corner of the Stage <br />(yellow). The topsoil and overburden was stockpiled in the northeast part of the area covering 2.84 <br />acres. The topsoil along the north side of Stage 3 - Part B remains undisturbed. This berm serves <br />two purposes, as a topsoil pile and an MSHA safety berm. We estimate there is approximately 48,000 <br />yards of overburden stored in Stage 6 (not on map), another 20,000 yards stored in Stage 3 - PART B <br />(brown) and 40,000 yards in Stage 4 - Part A. These piles are in a constant state of flux with material <br />being added and removed as needed. The settling ponds are still being used to clean process water <br />(dark blue). <br />9. In Stage 3 -Part B there is 31.00 acres of future lake area that needs little reclamation since it will <br />be covered with water. No additional reclamation was required. We will continue to monitor the area <br />seeded in Phase 2 - Part A, west of the southern plant site and do remedial seeding if necessary. <br />10. Mining will move into the western side of Stage 4 - Part A, this year (south of the railroad). The <br />mined material will be staged in the area mined in Stage 3 - Part B before being moved to the plant <br />for processing. <br />11. We are still placing overburden along the edges of the lake areas that are in their permanent <br />locations until the final grade is reached. <br />13. Weed control continued this year in the disturbed areas around Phase 2- Parts A & B and Stage 3 <br />- Part B. We sprayed Knapweed and White Top from May thru June 2015 with water soluble 2-4-0 <br />and Curtail and a mowing program is also used to aid in control. There is little or no control taking <br />place on properties surrounding the mine and seed is being wind blown in from offsite areas that we <br />have no control over. Spraying will continue as needed. We continue to monitor Tamarisk growth on <br />the site and do control work as warranted. <br />16. The mine has approved Augmentation Plans for all of the post 1981 lake areas. <br />21. Please refer to the 2015 Annual Report Maps for location of the areas of disturbance in the mine. <br />
