Long <br />Division Director <br />Colowyo has submitted a technical revision addressing the slide and springs associated with <br />the West Pit Pond. This submittal was part of the abatement of NOV C-95-005 that was <br />written on March 29, 1995. <br />In the TR, Colowyo was required to include an analysis of the areas associated with the <br />slides, remedial actions to stabilize the area and a program to monitor the West Pit pond <br />area. Part of the TR also includes CTL Thompson's recommendation regarding lining pit <br />benches and coal seams on the north end of the pit. The original recommendations for <br />lining the pit benches are found on page 13 of CTL Thompson report in Exhibit 19, Section <br />I.c. of the permit application package. <br />Colowyo is currently excavating the slide area while weather conditions are favorable. They <br />will soon be ready to implement the plan proposed in this TR. I would appreciate a <br />response from you regarding this TR by July 27, 1995.
