A.J. Waldron April 5, 1995 <br />Re: Bear Creek and Hubbard Creek April Monitoring <br />loaders were taken off the slide area. Estimated cost to attempt <br />monitoring Hubbard Creek sites on April 4 was Cat 966 loaders for <br />5 hours @ $85 = $425, pickups for 6 hours @ $25 = $150, Surface <br />Superintendent for 3 hours @ $60 = $180, Environmental Coordinator <br />for 4 hours @ $50 = $200, total cost = $955. <br />The following day, April 5, 1995, use of the loader(s) was denied <br />to continue work on the road. Hubbard Creek sites were then <br />accessed by foot for the regular weekly inspections and monitoring <br />of the Hubbard Creek Pond. Hubbard Creek Pond was dry, as usual. <br />A sample kit and field measurement devices were hand carried to <br />complete the monitoring at H-1, Hubbard Creek. Flow in Hubbard <br />Creek was measured to be 154 cfs, or 69,100 gpm, pH = 8.4, <br />conductivity = 140, temperature = 0 degrees C. Normally the hike <br />up Hubbard Creek takes about two hours. Sampling at H-1, Hubbard <br />Creek, increased the time to over two and a half hours. <br />At my request, Delta County rebuilt the Hubbard Creek Road in the <br />slide area during November, 1994. Within two weeks, on November <br />29, 1994, I considered the road unsafe to travel. Any additional <br />material placed down slope in the slide area will adversely affect <br />the inlet to the Deer Trail Ditch. Mr. Elmer Cline, owner of the <br />land in the slide area and a user of the Deer Trail Ditch, was on <br />site on April 4 to remind us not to place any additional material <br />down slope. I do not intend to ask for, nor would Somerset Mining <br />Company probably approve, further expenditures for repairs to the <br />Delta County Road. <br />Groundwater wells B-6 and H-10 and Hubbard Creek have been <br />monitored since at least June of 1986. The Somerset Mine has been <br />closed and abandoned since 1985. No useful information will <br />probably be gained by continual monitoring at these sites. The <br />Hubbard Creek road is now closed to vehicle traffic at the slide <br />area, possibly permanently. Although I consider the road in the <br />slide area unsafe, even for foot travel, I will continue to monitor <br />the Hubbard Creek sites, within practical limitations. Based on <br />the current condition of the Hubbard Creek road, we are considering <br />a revision to discontinue monitoring of the Hubbard Creek sites. <br />Please call if there are any questions. <br />S\ncer 1 ~~ <br />J <br />Thomas C.
