r Seep Inventory and Monitoring Program <br /> Page 4 <br /> Minimum Sampling Requirements: <br /> a) For each seep, spring or adit flow, one water <br /> characterization set of samples will be taken along with <br /> field parameters . <br /> b) Each field season, every identified site will be <br /> inspected twice, once at the beginning and once toward <br /> the end. Field parameters will be measured at each site <br /> during these inspections . Starting with the 1-994 field <br /> season, 20 percent of the sites will be sampled and the <br /> samples analyzed for normal sample parameters such that <br /> analysis of all stations will be completed in 5 years . <br /> Laboratory samples will be from a mix of the study area <br /> drainages. <br /> c) The sampling and monitoring requirements shall be in <br /> effect for a period of time dependent on the leveling off <br /> of the rate of rise of the mine pool. . The point of <br /> leveling off will be defined mathematically to the mutual <br /> satisfaction of SGC and DMG, based on data gathered <br /> through monitoring the rise of the mine pool . Monitoring <br /> and sampling shall continue 2 years after the mutually <br /> agreed upon point of leveling off has been reached by the <br /> mine pool . <br /> II . Stream Monitoring and Bulkhead Inspection <br /> 1 . Stream Monitoring : <br /> A monitoring program of surface waters will include: <br /> a) seep inventory and monitoring samples as outlined <br /> in B. I . 3 . <br /> b) the MLR monitoring point above the American Tunnel <br /> (CCl/CC1A) on Cement Creek will be monitored <br /> monthly for water characterization sample <br /> parameters and field parameters. <br /> c) The South Fork of Cement Creek at SF 17 will be <br /> sampled twice annually during low flow conditions <br /> (probably October and February) for field and <br /> normal sample parameters. <br /> d) Placer Gulch at PG 115 and California Gulch at CC <br /> 115 will be sampled annually during low flow <br /> conditions (probably September) for field and <br /> normal sample parameters if the mine pool surface <br /> elevation rises above 11 , 500 feet . <br />
