Pavlik <br />Division of Minerals & Geology <br />1313 Sherman St., Room 215 <br />Denver, CO 80203 <br />Re: NOV C-94-030 <br />Permit C-81-025 <br />Dear Ms. Pavlik: <br />Division of Mineta~s is neology <br />The Division's letter dated October 18, 1994 transmitted the <br />referenced notice of violation to Minrec. The following discussion <br />addresses the reclamation of three ponds which were the reason for <br />the NOV. <br />Pond P-1 <br />Pond P-1 was a large depression located in front of an 18" <br />diameter culvert. The drainage area for this culvert is <br />undisturbed. The culvert conveyed drainage under the county road <br />into North Thompson Creek. This pond/culvert arrangement was, in <br />my opinion, an ideal arrangement. The pond would allow sediment <br />and debris to settle so there was no concern about the culvert <br />being plugged. The pond was vegetated with large trees and <br />grasses. In my opinion this pond/culvert arrangement should have <br />been permanently left in place. However, the regulations do not <br />allow logic or sound engineering judgement to enter into the <br />equation. The pond has been reclaimed. <br />Pond P-2 <br />Pond P-2 is one of those "mysteries". It should have been <br />reclaimed when the mine was reclaimed in 1987. It has been in <br />existence for over seven years. This pond actually represents two <br />mysteries; 1) why is it still in place?; and 2) why does it take an <br />NOV to initiate the reclamation of it? The pond has been <br />reclaimed. <br />Pond P-7 <br />Pond P-7 was reclaimed late in 1993. The embankment of the pond <br />was breached. Unfortunately, the pond could still impound a small <br />amount of water. it could be argued that after the embankment was <br />
