August 2000 Monthly Report <br /> Page 2 <br /> work planned for these sites. During August, Sunnyside did not work on any of these <br /> sites. <br /> Vegetation growth has improved at each of the sites even though they are extremely dry <br /> this year due to a lack of significant rainfall. <br /> • Sunnyside Mine Pool Mitigation —Alkaline Solution Injection <br /> This project was not active in August of 2000 although 1.034 Mgal were pumped into the <br /> mine pool through the Terry Tunnel bulkhead valve to maintain a no discharge status at <br /> the Terry Tunnel discharge point. No alkaline material was added to this water. Included <br /> with this report is a summary sheet of the weekly flows and an analysis of the water <br /> exiting the Terry Tunnel portal (TT-INFEL). This water was periodically pumped into <br /> the mine pool through the bulkhead until August 24`"when the bulkhead pipes and valves <br /> were permanently grouted shut in preparation for placement of a near surface bulkhead <br /> and reclamation of the Terry Tunnel portal site. <br /> "B List" Projects <br /> • Columbus Mine Portals — Mine Waste Dumps <br /> • London Mine Portals —Waste Dumps <br /> Work, permitting or arrangement for access is not planned until it becomes evident that <br /> the work plans for these projects require implementation. <br /> • Mayflower Facility— Upland Hydrological Control <br /> This project was completed in October, 1999 and accepted by DMG as complying with <br /> the Consent Decree work plans and MLR Standards in November, 1999. <br /> Diversion C was actively diverting flow around the Mayflower Mill facility throughout <br /> the month. <br /> Flow from Diversions A and B tapered down to near nothing during May and they were <br /> basically dry at the end of July although during August they diverted flow intermittently <br /> during and after rainstorms. Near surface groundwater flow that these diversions capture <br /> and divert around Tailings Pond #1 will now remain low unless infiltration and runoff <br /> from rain storms increase. <br />
