a` ~ <br />6. The East end of the Hawk's Nest Mine contains an active spring discharging <br />at the rate of .5 gallons/minute. The path of the flowing water starts at <br />the east portal and crosses a road culvert into a drainage ditch. The <br />ditch is heavily rip-rapped for 50 feet and then stops. The water leaves <br />the ditch and flows across the reclaimed slope (15 degree elope) into the <br />North Fork. Some significant gullies have formed into the reclaimed area <br />(this area contains no topsoil). After discussing this problem with Susan <br />Burgmaier and running the drainage through SedCad, the problem appears to <br />be more than the spring. The 10-year event is 51.52 cfs, the 25-year <br />event is 7B cfs and the 100-year event ie 122.5 cfs. These gullies are <br />probably a result of the natural drainage through the culvert. The <br />question is 1) should we do anything 2)should we reconstruct the lower 350 <br />feet of the reclaimed area to account for a drainage ditch and/or 3) <br />should we use the geomat or rip-rap. Depending on which way we go with <br />this, it could be a big ticket item. <br />7. To keep the pond, or to not keep the pond....that is the question.... Any <br />thoughts??? If we pull the pond then we need to construct 2 ditches to <br />the North Fork ($). <br />8. Refuse Pile- If we need to do any work at the refuse pile, we might be <br />tight on money. I'm counting on Delta County to reclaim the pile, as they <br />have stated. I'm still not sure how we can do this when the area is not <br />incorporated in their CD. Something to think about..... <br />9. In order to access the topsoil pile, we have to cross the railroad tracks. <br />Knowing the railroad, they will want a separate insurance policy (they <br />told me at one time a policy is needed if any work is done within 20 feet <br />of the tracks). Can we avoid this? This will also be a factor when we <br />pull the pond. I don't need any more gray hairs. <br />10. This work should coordinate with the best possible time for seeding the <br />area. Please let me know what the best time for seeding would be, so I <br />can adjust the project accordingly. <br />11. In looking at all of the possible tasks and options we should~be able to <br />spend the entire $80,000. Until the bid is out and we have a contractor, <br />I only need to see the site once a month for partial and complete <br />inspections. During this time where I only do inspections, I would like <br />to use the normal travel money rather than dip into the Hawk's Nest <br />reclamation fund. Please let me know what you think about this. <br />I will be at Hawk's Nest on July 1 to meet Miner's Inc. for the final inspection. <br />If you want to look at this area and see the job that Miners did, this may be the <br />best time. Let me know what you think about the items mentioned above. <br />c:\hawk\940614 <br />
