Jared Ebert <br /> July 8,2019 <br /> Page 4 of 18 <br /> Plantings will be installed when mining commences in the East Cell (Phase 2). Plantings will <br /> be installed by a reclamation contractor in September and hand watered until the ground <br /> freezes. Plantings will be monitored in the spring to make sure they are leafing out, replaced <br /> as necessary to provide the quantities as originally installed and watered as necessary <br /> through the first three growing seasons to establish. <br /> Common Name Botanical Name Planting Size Quantity <br /> Plains Populous 10 gallon 36 <br /> Cottonwood deltoides <br /> American Plum Prunus 1 gallon 40 <br /> americana <br /> Choke cherry Prunus 1 gallon 40 <br /> vir iniana <br /> Western Sand Prunus besseyi 1 gallon 40 <br /> Cherry <br /> Coyote willow Salix exi ua 1 allon 40 <br /> This information has been added to Exhibit E and Exhibit F-1 <br /> Rule 6.4.7, Exhibit G, Water Information <br /> 13. Page G-1 states, "runoff from disturbed areas, piles material and operating surfaces will likely be <br /> diverted to the settling pond for detention and cleansing." Please revise this page to include a <br /> plan/discussion about how water from disturbed areas (including stockpile areas) will be diverted to <br /> settling ponds? Please update Maps C-4 and C-5 to depict run-off diversion structures. <br /> Exhibit G has been revised to describe water handling in more detail. Exhibits C-4 and C-5 <br /> have been updated to show runoff handling to the extent practical given the flexible nature <br /> of mining. <br /> 14. Map C-4 does not show settling ponds in the Phase 2 (West Area). Run-off control for this area will <br /> need to be evaluated and addressed in the discussion and maps identified in the item above. <br /> A settling pond has been added to Exhibit C-4. A discussion has been added to Exhibit G. <br /> Both revisions have been prepared in conjunction with the response to Comment 13. <br /> 15. Similar to the adequacy item for the mining plan section about wet-mining the South Area and <br /> dewatering operations. Please clarify if any dewatering will occur at the South Area? If dewatering <br /> is planned for this Phase, an evaluation of the impacts of this activity and possible mitigation <br /> measures will need to be addressed in this Exhibit. <br /> The south area will be dewatered as described above. Dewatering water pumped from the <br /> South Mine Area will be discharged to the downstream end of the Brighton Return Ditch (See <br /> Exhibit C-4) near the east end of the mine limit. The water will flow directly into the South <br /> Platte River via the Brighton Return Ditch. <br /> Aggregate Industries—WCR,Inc <br /> 1687 Cole Blvd Suite 300 <br /> Golden,CO 80401 <br />
