<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 <br />inspection and the facts or evidence supporting the enforcement action. <br />material(sediment and cobbles) entered the stream. At one location a boulder had been toppled <br />over the fence and was laying in the middle of the stream channel. <br />Henry Barbe of MCC was contacted by radio and joined Boulay and Ms. Johnston at the location <br />of the damaged silt fence. Mr. Bazbe indicated that the berms were constructed in response to <br />a recent MSHA inspection. <br />During the inspection of the Electric Substation construction, it was noted that trucks were <br />travelling on the Light Use Maintenance Road located between the Main Access road and the <br />Substation Access Road. Light-use and access roads are experiencing heavier than anticipated <br />use due to slide damage/failure of the main hauUaccess road in Sylvester Gulch. Therefore, <br />MCC should reevaluate whether these roads are capable of sustaining the heavier usage. Please <br />review the permit documents, and submit a revision if changes to the approved documents are <br />required. Likewise, if roads are needed in addition to those already permitted, then a revision <br />will be required prior to installation. <br />Hydrolo2ic Balance <br />The construction of the berm on the east side of the light use road located to the east of the main <br />hauUaccess road in Sylvester Gulch resulted in impacts to water quality in Sylvester Gulch <br />channel. Streamflow was impeded due to the silt fence collapse at more than one location. <br />Streamflow appeared silty and was clearly impacted due to the addition of sediment. Please refer <br />to the above discussion under "Roads" for a description of the location and damage to the silt <br />fence. <br />Some water had backed up in the Sylvester Gulch channel as a result of the slide movement <br />impinging on the flow in the stream channel. This apparent area of impeded flow was not <br />associated with the damaged silt fence. This location is in the northern portion of the slide. <br />Along the toe of the slide, Streamflow in the gulch bottom appeared silty due to the addition of <br />sediment. <br />Topsoil <br />At several locations along the light use road in the area of the constructed berm, it appeared that <br />the berm construction material was placed on top of vegetated azeas alongside the stream. <br />Topsoil and subsoil beneath the vegetated azeas were not sepazately removed and segregated. <br />It is estimated that a minimum of 30 cubic yards of topsoil have been impacted. <br />4 <br />
