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 d`iring the inspection <br />and the facts or evidence supporting the enforcement action. <br />storm events. The road ditch needs to be re-graded and the outlet to the natural drainage <br />re-defined. <br />3) The upper most segment of the light use road to Substation B (beyond the Fontanari <br />quarry) was rutted due to passage of a vehicle during muddy conditions, and maintenance is <br />warranted. <br />4) On the UTL haul road, there was minor debris accumulation at the inlets of the lower <br />Coal Creek dip section culverts that needs to be removed. General road ditch maintenance <br />was warranted along the road in the immediate vicinity of the loadout facility. <br />5) On the permanent road up Coal Canyon, between the large double culverts on Coal Creek <br />and the upper dip section, ditch grading is warranted in various locations. Also, down- <br />cutting has initiated at the outlet of the road dip just up the road from the upper dip section <br />crossing. Stabilization is warranted to prevent headword erosion into the roadway. <br />6) Minor erosion was observed along an upper segment of the Haul Road 5 road ditch relief <br />channel in the immediate vicinity of the Xcel dozer shed (between the dozer shed and the <br />riprapped lower channel segment). Stabilization measures are warranted. <br />Hvdroloaic Balance <br />Structures in most areas appeared to be functional and properly maintained. Sediment <br />Ponds and SAE sumps in all areas were either dry or contained only shallow puddles. <br />Drainage and sediment control maintenance items note in recent inspection reports had <br />been properly addressed. This maintenance work included rill and gully stabilization at the <br />CBA-2 borrow area and at the lower end of the ephemeral channel along the lower side of <br />the reclaimed explosives bunker road. Also minor erosion repair work had been completed <br />within the North Portal reclamation area, and along the upper end of the conveyor route <br />sediment control berm. A large boulder had been removed from the RSRDA upper diversion <br />channel, as requested in the January 31 inspection report. Silt fencing damaged by cattle <br />had been replaced. <br />Minewater Discharge Pt. 016 was functioning properly when viewed on 3/26. Discharge <br />was clear, flow approximately 270 gpm. The Discharge 001 valve had been closed at the <br />portal. The Discharge 002 valve (siphon tube outlet from the backfilled Northwest Intake <br />Portal) has also been closed, such that all minewater inflow is discharged from Discharge <br />Site 016.. Based on the Well N-1 depth to water reported in the 1~` quarter, 2003 <br />Hydrology Report (75'), and elevations specified in Permit Figure 14-7; approximate <br />elevation of the water pooled in the mine workings is 4758'. This indicates that the pool <br />elevation is safely below the elevation of the sealed NW Intake Portal (4762'1. The <br />approximate pool elevation of 4758' corresponds with the flowline elevation for the 016 <br />discharge pipe specified in Permit Figure 14-8. <br />4`" Quarter 2002 CDPS self monitoring report indicated anon-compliant discharge for an <br />iron exceedance from Discharge Point 016. This was the first such non-compliant discharge <br />2 <br />
