Cattany <br />Division Director <br />Natural Resource Trustee <br />The Division has reviewed the permit Amendment application for the Parkdale Quarry, MLRD <br />Permit # M-1997-054, and has the following initial comments. <br />I) Introduction. <br />The Amendment proposes to increase the mining limit and depth for both the granite <br />quarry and the sand and gravel operation. It also proposes to change the post mining land <br />use for both sites to be water storage rather than rangeland/wildlife habitat as currently <br />approved. No changes to the existing 3 acre, sandstone quarry. The sand and gravel site <br />mining depth will change to mine below water table. Mining high wall to be 40 foot with 20 <br />foot benches final Pit slopes configuration to be 3:1 or gentler below water line. <br />The granite quarry covering 64.3 acres is proposed to be expanded to approximately 83 <br />acres with 72.5 acres to be affected. Depth of mining will go from the current 5780 depth to <br />5300 feet an increase in depth of 480 feet. Once mining is completed the sand and gravel pit <br />will be clay lined and used as water storage at later date, and the quarry will also serve as <br />such but will not be clay lined. The 40 foot bench with 50 foot high wall will be filled with <br />water up to 5800 feet. At present, the operator, under tier water substitute supply plan <br />approved by SEO, only has enough water to account for consumptive evaporative. The <br />operator feels they should have no problem finding an entity that has adequate water <br />supply to purchase both pits once it is reclaimed as proposed. <br />II) EXHIBIT C Mining and Pre-Mining plan Map. <br />1) Has the operator included all roads, buildings, oil & gas wells, lines of any kind <br />including power lines on the area to be affected and with in 200 feet of all boundaries of <br />such area ? If not, please provide a map showing all those listed above in the per- <br />mining plan map. <br />1 Office <br />Office of of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
