III. COMMENTS-COMPLIANCE
Below are comments on the inspection. The comments include discussion of observations made during the
inspection. Comments also describe any enforcement actions taken during the inspection and the facts or
evidence supporting the enforcement action.
Roads
There are approximately 13.5 miles of haul roads within the permit area that have been modified
and reduced to postmining condition and retained as permanent access roads. All other
operational road sections other than those listed below have been fully reclaimed. SCC has
retained the following designated roads as permanent: Pre-Law Road, Road C, Road E, Road
El, Road F, and South Road. Permanent roads are shown on permit Exhibit 13-2A "Postmining
Topography and Permanent Features", and also are delineated on Exhit A "Bond Release Area"
of the SL-4 application. Permanent roads within the permit area were approved for Phase I bond
release within SL-1 (final approval date 2/22/07). Please refer to the Division's proposed
decision for SL-1 dated December 27, 2006, for discussion of permanent road compliance
evaluation. No permanent road segments are included in the SL-4 release request areas.
Backfill & Grading
The three separate areas subject to the SL-4 release request were walked during the inspection,
and observations were made with regard to approximate original contour and erosional stability
of the reclaimed landscape. Postmine drainage channels within each area were walked along the
entire length of each channel. Based on observations made during this and previous inspections
(from the August 2006 SL-1 inspection to the present), the Division's general conclusion is that
reclaimed areas have been restored to the approximate original contour of the pre-mining
landscape. The present surface configuration achieved by backfill and grading of the mined areas
closely resembles the general surface configuration of the land prior to mining. Reclaimed areas
blend in well with existing undisturbed landscape. Comparison of the Postmine Contour Map
(Exhibit 12-9) and Postmining Topography and Permanent Features Map (Exhibit 13-2A), to the
USGS 7.5 minute Quadrangle Maps of Mount Harris and Milner, Colorado indicate that the
major pre-mining drainages were reconstructed in the appropriate locations and additional
drainage density was added to the post-mining landscape by constructing additional post-mine
channels. Backfill and grading compliance for the three distinct areas subject to the SL-4
application are addressed separately, below.
East Wadge Area
The 125.8 acre parcel referred to as the East Wadge Area comprises the major portion of the SL-
4 release request, and includes reclaimed slopes east of Road C in the PM-8 watershed, including
much of the length of Post-Mine Channel PM-8. The East Wadge Pit was one of the last areas to
be reclaimed at Seneca II Mine. Long, relatively steep, southeast facing slopes predominate.
