111. 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 d~uing the inspection
and the facts or evidence supporting the enforcement action.
3) Please address the apparent inconsistency between permit text and Exhibit 26, with
regard to RSRDA terrace drain width, and amend the permit as appropriate. Please address
the inconsistency and amend the permit prior to the Phase I bond release inspection.
Revegetation/Reclamation Success
Seeded vegetation had not yet germinated on areas revegetated in November 2002.
Perennial grasses and widely scattered seedling shrubs germinated in the fall of 2002 on
areas revegetated in Aprif 2002, along with significant volunteer of annual wheat from seed
in the straw mulch. No germination of species interseeded on older revegetation areas of
CRDA-2 in the fall of 2001 was apparent. It is too early to evaluate success of these
recent seeding efforts.
Outlying areas seeded in 2000 and 2001 included portions of the North Decline Area (Ute
Water Corridor), as well as disturbed areas at the South Fan and Borrow Area and 2West
Portals. Initial establishment of grasses and shrubs appears promising in most areas,
although establishment is relatively sparse on the steep upper portions of backfilled slopes
at the 2West Portals.
Of the permanent reclamation areas seeded in 1994 or earlier, CRDA 1 supports a diverse
cover of grasses and shrubs, with a scattering of perennial (orbs, and represents the most
successful of the older seeded areas. At CRDA-2, slopes appear stable, but large areas of
the pile are dominated by four wing saltbush, with minimal perennial understory and low
diversity. Interseeding was conducted in 2001 due to the documented low diversity of the
stand. At the North Decline Area, there are good numbers of fourwing saltbush and
greasewood over most of the site, but perennial understory is spotty with a significant
cheatgrass component, which is fairly typical of upland greasewood habitats in the general
area. Slopes in the area are gentle, with no indications of erosional instability.
Refuse Area Slope and Terrace Drain Measurements and Compliance
Evaluation
Transects were run on refuse area outslopes along the fall line to estimate slope gradients
of the benches reclaimed in 2002. Grade was estimated using an abney level, sighting
point on assistant based on eye level of recorder (e.g. 5'7"). Slope distance was measured
with a 300 foot tape. Bench height was later calculated by conversion of slope % to
degrees and application of trigonometric formula [Sin A =a/c, where A=angle measured in
degrees, c=measured slope in feet (hypotenuse), and a=bench height in feet]. Terrace
drain widths were measured along each transact. Estimated slope gradients, measured
terrace drain widths, and calculated bench heights are presented on the following Tables for
CRDA-1, CRDA-2, and RSRDA. Approximate transect locations and orientations are
depicted on the aerial photos attached to this inspection report.
