,air of the stock tanks at the Seneca I1-W mine were full of sediment, and require cleaning. Along the G-haul road, <br />the rock spillway on T-22 was washed out, and has not changed since the last inspection. Some minor repairs on <br />the G-road were noted, but extensive erosion has occurred on all road ditches and permanent drainages. All of this <br />disturbance was noted in the previous inspection report, and is collected in Pond 005. The haul road G ditches <br />have down cut roughly 2 feet to 5 feet above G-5 culvert. The natural drainage above and below G-5 culvert has <br />eroded to a depth ranging from 5 feet to 10 feet. This entire drainage requires repair. The ditch above Culvert G-3 <br />has down cut roughly 1 to 2 feet and requires repairs. <br />The operator has yet to completely install therip-rap on the B-Pit NOV drainage. Rock has been piled, but weather <br />conditions have delayed reestablishing the drainage. The entre drainage on the B Pit needs to be repaired. Heavy <br />rains have dovvncutted the channel to a depth of 2 feet. The lower portion of 006 drainage also needs to be <br />repaired. Heavy rains have washed the rock Crom the channel. <br />Backf'illing & Gradine Backfilling and grading in the A-Pit appears to be complete for this year. The C-Pit has <br />not been backfdled. The operator should make note that the bacl<filling & grading map shows the C-Pit to be <br />wmpleted in 1997. Previous backf'illed slopes appear stable. Numerous erosion features were noted throughout <br />the backfilled azea with the heavy precipitation this year. Repays should be made m acwrdance with the rill and <br />gully plan. <br />Explosives Explosive storage units were property secured and signs posted. <br />T i Topsoil has been stripped in advance of the A Pit and placed in existing topsoil piles. Once the piles are <br />complete, a temporary seed mix should be applied and signs put in place. It appears that all of the topsoil placed on <br />regraded areas this year was live handled. Some additional topsoil needs to be removed in the upper A-Pit Area. It <br />does not appear that all of the topsoil has been removed from this area. <br />Topsoil depths were verified in portions of the 1996 and 1997 reclaimed aeeas. The GPS was used to determine the <br />azea of topsoil replacement as well as the sample locations. The GPS information will be provided to the operator <br />once the data is compiled. The following topsoil depths were noted; <br />1(,~per 1996 Area <br />9601-IS" <br />9602-19" <br />9603-27" <br />97-04- <br />l~pper 1997 Area <br />9705-18" <br />9706-IS" <br />9707-13" <br />9708-10" <br />9709-]0" <br />9710-14" <br />
