• • <br />MR. ROBERT G. LIDDLE <br />DECEMBER 2, 1985 <br />PAGE 2 <br />Concern B - Spoils Springs <br />By the end of April, 1986, CYCC will complete a spoil spring and seep <br />survey capable of identifying the spoil spring waters leaving the regraded <br />spoils. A proposed monitoring program will be submitted to the CMLRD and CDOH <br />by May 15, 1986, and provided regulatory approval is obtained, the monitoring <br />program will be installed by the end of June. <br />Concern C -Parameters of Concern <br />Chemical values from spoils springs will be compared to the CDOH stream <br />water quality standards and parameters included as effluent limitations. Once <br />this information is available and based upon joint meetings with the CDOH and <br />CMLRD, CYCC will request that adjustments be made in our monitoring program. <br />Concern D - Reevaluation of Hydrologic Monitoring Program <br />In order to determine whether <br />CYCC will reevaluate their hydrologic <br />this review a technical revision will <br />revised monitoring program. We will <br />March, 1986. <br />or not all monitoring sites are needed, <br />monitoring program. Upon completion of <br />be submitted to the CMLRD detailing the <br />attempt to have the program functional by <br />Concern E - Spoil Wells Pump Tests <br />The spoil wells will be tested to determine the permeability of the spoil <br />and results will be submitted to the CMLRD. Review of water levels in spoil <br />wells reveals that during winter periods water levels are very low (one well <br />is dry), making testing infeasible at this time. Therefore, testing will be <br />completed during late spring or early summer of 1986. <br />Concern F - Remodeling of Spoils Aquifer <br />A preliminary spoils spring aquifer model, based on data from mines in <br />the local area, will be prepared and submitted to the CMLRD by January 31, <br />1986. This preliminary model will be further refined based upon the moni- <br />toring data obtained in 1986. <br />Concern G - Elevated TDS and 804 Levels <br />An evaluation of a water mass balance for Fish and Foidel Creeks in- <br />cluding predictions of future stream water quality will be completed and sub- <br />mitted prior to next spring's runoff. <br />Mine 3 Letter <br />Concern Over Bailing of Wells <br />CYCC will commence a program to bail all bedrock ground water wells at <br />both the Mine 3 and Eckman Park sites. Both bailed and unbailed samples will <br />be collected in the interim, allowing a comparison of the two methods. <br />
