Producers will be stockpile at Boulder's 63'~ Street WTP, Boulder's Betasso WTP, and <br />Longmont stockpile at their WTP. For this year, we would seek approval of the North ;trea only as <br />we have additional monitoring of groundwater level and quality for the South azea. The City has had <br />excellent experience with the application of WTP residuals as a top soil. Excellent growth of native <br />grasses on slopes as great as 2:1 at our 1994 reclamation of Conda pit mine above Eldorado Springs. <br />I have included portions of a poster presentation presented at the 1996 High Altitude Revegetation <br />Workshop m Fort Collins by David Buckner and Lynn Riedel. Post-monitoring of Conda site has not <br />exhibit any phosphorus deficiency. In fact the vegetation cover had developed to an erncent beyond <br />that typically found in the first year stands. <br />If you have any questions or concerns, please call me at 441-4080. <br />Sincerely, <br />Paul Heppler <br />Resource Recovery Specialist <br />
