Sediment pond 005, 006 and 017 were observed to <br />have damp areas below the toe of the embankment. The reports did not indicate that this observation <br />posed a concern. Ponds 015 and 016 have previously experienced surrounding land instability <br />previously. The September 2013 reports noted that the previously identified landslides appeared stable. <br />If you have any questions feel free to contact me (303) 866 -3567 ext. 8120. <br />Sincerely, <br />Janet Binns <br />Environmental Protection Specialist III <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines <br />
