_~ <br />III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the inspection <br />and the facts or evidence supporting the enforcement action. <br />General Comments <br />This was a partial mine site inspection. Primary purpose of the inspection was to view revegetated areas in <br />Section 16 that would be affected by future disturbance associated with South Taylor mining, as well as the CSU <br />shrub establishment plots and East Pit revegetated areas in the general vicinity of the CSU plots. Brief <br />inspection was also made of the locations along the lower section of the West Fork Good Spring Creek, where <br />two sediment ponds would be constructed to handle runoff from the southern portions of the South Taylor pit <br />disturbance area. I was accompanied on the inspection by Colowyo Environmental Engineers Curt Blunt and <br />Tony Tennyson. Environmental Coordinator Tay Tonozzi was present during follow-up discussions after the <br />inspection. <br />Weather was partly cloudy, cool and windy during the inspection; ground surface was dry in most areas. <br />Revegetation-Section 16 Area <br />We viewed the general location where the proposed South Taylor temporary out of pit spoil disposal area would <br />be located. The location includes a broad, relatively flat bench area, with an area of moderately steep east <br />facing slopes to the east of the bench. These areas were seeded in 1994/95, and appear to be relatively typical <br />of much of the reclamation at Colowyo. The relatively flat benches are dominated by wheatgrasses and cicer <br />milkvetch. Intermediate wheatgrass was still included in the mix seeded at that time, and appeared to be the <br />dominant grass. Some widely scattered sagebrush plants were present on the bench, but woody plant density is <br />quite low. In contrast, the steeper east facing slopes support relatively high density big sagebrush shrub <br />patches, particularly along the upper slope where snow may accumulate on the lee side of the bench. This <br />pattern seems to occur in various locations on the reclaimed areas at Colowyo, with shrub patches (primarily big <br />sagebrush) associated with topographic features and aspects that allow for somewhat higher soil moisture <br />conditions than are typical on the broad grass dominated areas that tend to lack significant topographic variation. <br />We looked at a fence shrub planting area on the bench, designated 956, The area has become overgrown with <br />grass, but patches of Woods rose have persisted well inside the fenced area. A sharptail grouse was flushed <br />out of a small sagebrush patch just outside of the 958 fenced shrub area. <br />Revegetation-East Pit Area <br />The first stop here was an area that had been seeded between 1997 and 2003, and which had been burned <br />(unintentionally) in October 2005. The fire had burned through a fenced shrub establishment area (1999A). <br />Areas both inside and outside of the fenced shrub establishment area are dominated by cool season grasses <br />and cicer milkvetch, with very few shrubs, although the areas generally seem to be more diverse than the <br />1994/95 seeded areas on the flat bench described previously. The East Pit areas observed were located on <br />relatively gently sloping areas with a predominant easterly aspect. Perennial grasses and (orbs appear to have <br />recovered quickly and completely from the burn, and the burned areas are now difficult to separate from the <br />unburned areas. A small herd of pronghorn was observed in this area. <br />Patches dominated by annual brome (cheatgrass and/or Japanese brome) were observed in various locations of <br />the East Pit reclamation, including areas in the vicinity of the burn. Several of the patches were up to several <br />acres in extent, and it appears that cheatgrass could have the potential to become a significant problem. The <br />operator is developing a plan for cheatgrass management that will be included in a revised revegetation plan to <br />be submitted in May 2008. <br />The CSU/DRMS shrub establishment study plots are located further downslope to the east of the burned area. <br />These plots were installed in the fall of 2000, and include various different soil thickness and seeding treatments, <br />fenced and unfenced. CSU will be collecting data from the plots and preparing a report later this year. Casual <br />observation of the plots reveals impressive establishment of low shrubs (primarily big sagebrush, but also silver <br />3 <br />
