Seep Inventory and Monitoring Program <br /> Page 5 <br /> 1 . Stream Monitoring - Cont <br /> e) Eureka Gulch at EC 34 will be sampled annually <br /> during low flow conditions (probably September or <br /> October) for field and normal sample parameters. <br /> f) The American Tunnel flow before treatment will be <br /> sampled monthly for field and normal sample <br /> parameters. <br /> g) The Terry Tunnel portal will be inspected for flow <br /> quarterly, when accessible. Existence of flow will <br /> trigger a bulkhead inspection. <br /> h) The mine pool water at the American Tunnel bulkhead <br /> will be sampled annually through the 1" pipe. The <br /> sample will be analyzed for water characterization <br /> sample parameters and field parameters except flow. <br /> 2 . Bulkhead Inspection: <br /> a) The Terry Tunnel bulkhead will be inspected <br /> annually. At this time, the pressure gauge will <br /> also be read. If the mine pool surface rises above <br /> 11 ,600 feet in elevation the inspection interval <br /> will become semi-annual . <br /> b) The American Tunnel bulkhead and tunnel will be <br /> inspected weekly after valve closure for the first <br /> month , monthly for the next five months and then <br /> quarterly thereafter. Pressure readings from the <br /> installed gauge will be read during each <br /> inspection. <br /> The monitoring and bulkhead inspection schedule will remain in <br /> effect until two years after leveling off of the rate of rise of <br /> the mine pool as outlined in B. I . 3 . <br /> III . Reporting <br /> The data collected during bulkhead inspection, stream <br /> monitoring and during data collection for the seep, springs <br /> and adit flow inventory study will be reported in a separate <br /> section to be added to the MLR Permit No. M-77-378 annual <br /> report. This section will also include a narrative to <br /> correlate information from the above monitoring and inspection <br /> programs related to TR-14 . <br /> SGC will notify DMG immediately if there is increased <br /> discharge to any surrounding drai_naq e related to flooding of <br /> the Sunnyside Mine workings . <br /> 11 (, <br />
