May 16, 2011 C- 1982- 057fSeneca II -W Mine SLB <br />Culvert ME -1 was conveying heavy flows from Dry Creek under the haul road. The outlet end of the culvert was <br />downcutting approximately 6' at the culvert area and beyond the permit boundary. This area was included in the <br />citation for Notice of Violation No. CV2011 -001, also for failure to ensure that haul roads do not cause "additional <br />contributions of suspended solids to streamflow or to runoff outside the permit area" as required by Rule <br />4.03.1(1)(b). <br />Road J was in good condition. With a few minor exceptions, the outfalis of the Road J culverts (maintained last <br />fall) were in good condition. The operator will need to clear the dissipating areas above the silt fences at B <br />and J4. The inlet side of J4 will also need to be repaired. <br />The Ridgeline Access Road between the ClD and A/B pits was in good condition. Light Use Roads 3, 4, and 5 <br />were not accessible due to muddy conditions. <br />Light Use Road LU -2 exhibited a gully down its entire length from topsoil stockpile (TSS I) to the well <br />pumphouse; the gully was approximately 8" deep and 12" wide. The operator needs to regrade the road (LLU- <br />2) and reestablish a ditch for road surface drainage. <br />The culvert at the intersection of the Oil Well access road and the 006NE1 drainage needed to be cleared on the <br />inlet side. <br />Haul Road G and the associated ditches and culverts were in good condition. <br />REVEGETA TION —Rule 4.15 <br />Vegetative 'over; Timing.- <br />The soils were saturated, the temperature was unusually cool and large patches of snow were still present which is <br />unusual for this time of year making the vegetation late sprouting. The early season forb species were just starting <br />to flower. Some perennials grasses and fortis were starting to sprout and the shrubs were at bud - break. Some of <br />the species seen sprouting in the reclaimed areas were alfalfa, western spring beauty, pennycress, alfalfa and <br />prairie onion. Aspens were breaking -bud within one of the shrub enclosures. <br />SLIDES and DAMAGE -Rule 4.12: <br />Several slides were observed on the reclaimed areas: <br />In the vicinity of Pond 006, (Area 2 on Figure 1), cracks were developing on the inlet slope below the intersection <br />of MEHR and the Oil Well Access Road. Area 3 is a scarp adjacent to the undisturbed area on the south side of <br />the lower end of 006 Gulch. Area 4 is a large slide extending from the light use road LU -2 down to Haul Road A <br />along the undisturbed/disturbed area boundary. Area 5 is a scarp between the facilities yard and Haul Road A. <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 4of15 <br />
