(Page 2) MINE ID # OR PROSPECTING ID # M-2001-054 INSPECTION DATE 915/07 INSPECTOR'S INITIALS RCO OBSERVATIONS This partial inspection was performed by the Division as part of its monitoring of Construction Materials 110 permits, and in response to the operator's incomplete request for bond release. (The release request was not sent by certified mail, though required by Rule 4.17, so it is therefore regarded as incomplete.) The inspection was scheduled so that the operator could be present during the inspection. The required permit ID sign and boundary markers were posted. The channel crossing at the top of the entrance ramp has been repaired with new culverts, and the sediment channel has been partially filled (again) with fine sediments. The operator has performed the maintenance to the pond and spillway, to ensure that it continues to function as designed. This acts to correct a problem noted in a previous report. Most of the permit area excavation has been completed, and much of the reclamation earthwork and grading have been completed, though it is becoming apparent that long-term stability may a difficult condition to attain. There were several examples of this observed during this inspection, such as: The runoff from upgradient carries a large load of coarse sediment, which regularly fills the channel, requiring constant maintenance. The channel contained about 1000 cubic yards of newly- deposited aggregate, which the operator had not yet removed. The upper bench contained another 1000 cubic yards ofnewly- mucked aggregate in a stockpile that had yet to be processed or removed. The pit benches are lower in elevation than the adjacent constructed channel, which will allow runoff to enter the pit. The slopes exhibit several separate scars of erosion or failure that the operator has mended, but all of them occurred in 2007. The natural, uncontrolled meandering of Bridal Veil Creek upstream from the permitted area will eventually cause it to enterthe pit and degrade the slopes and benches, and leave the site without passing through the sediment pond. There is no present means to provide channel control on lands uphill from the site. The operator may need to consult with an engineer to determine what must be done to ensure stability. There are still parts and debris, broken equipment and stockpiles of gravel and soil onsite, which are not approved in the reclamation plan. These items will need to be removed, and in the case of the soil, be spread onsite for reclamation use. The slopes are required to be revegetated according to the approved reclamation plan, though little vegetative growth was observed on the slopes. The site will need to be reseeded until sufficientvegetation has become established. The reclamation items that are lacking were discussed onsite, and the Division's determination that release could not be approved was subsequently discussed further by email after the inspection; the operator has withdrawn the release request. The lower bench of the site, where much of the onsite runoff reports, is not bermed to contain or control stormwater. Numerous locations along the outer margin of the bench exhibit small erosional features where runoff has drained from the site, without benefit of a sediment stilling basin. The operator stated that he has no stormwater management permit. The date. No further items were observed during the inspection.
