• y • • • <br />Ms. Sandi Marek, Colo Dept of Health <br />May 3, 1990 - page 2 <br />Ashmore pits advance, the north ends of these boxcuts have been used as util- <br />ity waste (ash) disposal areas. It is likely that the same scenario for ash <br />utilization could result in the boxcuts within Middle Pyeatt Gulch, There- <br />fore, Trapper proposed to establish an ash monitoring well at the north end of <br />the Ashmore pit boxcut in Middle Pyeatt drainage. The HI aquifers will be mon- <br />itored for potential impacts to the groundwater resource. <br />Finally Trapper intends to install a Parshall Flume and Stevens Recorder ae <br />two NPDES locations on our mine site. Flumes will be installed in Elk (010) <br />and Ute (008) Gulches for continued assurance of proper flow documentation <br />associated with these sites. <br />Sandi, if you have any questions please contact me. <br />Sincerely, <br />0 <br />William Agnew <br />Sr. Envirorunental Engineer <br />wA/jb <br />~CDOH\MAY03) <br />c: J.M.
