Last year we forwarded a proposal to <br />manage the seepage and obtained the necessary regulatory approvals to reopen the adit <br />and manage seepage water through evaporative spraying and irrigation application of <br />water on the 9360 bench area immediately outside the adit portal. <br />The adit was reopened last Fall and the existing adit plug partially removed such that we <br />could gain access to monitor the seepage and develop a plan to address the issue. <br />Those evaluation efforts are underway at the present time and we will be contacting <br />you when a remedial plan proposal has been developed. Seepage commenced during <br />mid- May and continues at the present time. Flows reached a peak of approximately 60 <br />gpmc and is presantly 't sprro::i•••a,ely half th,+, rare 134 SFPnI, wo o%aect flntAls *_o <br />diminish further over the next several weeks. <br />If you have any questions regarding the present activities at the Bulldog site, please <br />contact me in our San Francisco office; my direct line telephone is 415.983.8180. <br />Very Truly Yours, <br />cc: F.
