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 />parameter s. <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 drainage related to flooding of <br />the Sunnyside Mine workings. <br />
