October 2000 -~3- 003-2191 <br />• (K) Provisions for the retrieval of windblown wastes, on-site or off-site <br />If solid wastes are blown from the working face and escape the fencing, the solid.waste <br />will be picked up by the site personnel and, if required, temporary labor. <br />(L) Conceptual plans to be implemented if the contamination of surface waters or <br />groundwaters occur, or if nuisance conditions are confirmed beyond the site <br />There are no surface water features immediately adjacent to the site. The perimeter <br />channels planned for each phase of the facility will collect all surface water from the <br />facility and convey it to retention ponds located on the western edge of the site. This <br />water will not be released from the ponds, which have been designed to contain the <br />100-yeaz storm. Therefore, existing surface water quality will not be impacted by run- <br />off from the facility .Drainages could only be contaminated by wind-blown debris. <br />Daily recovery ofwind-blown materials will prevent any site or off-site contamination. <br />There is no groundwater under the site for more than approximately 60 feet. This, in <br />conjunction with the 3 foot compacted liner and naturally low permeability of the <br />natural shale materials beneath the site, indicate [hat the contamination of groundwater <br />should not be a potential issue. In the event that the water monitoring wells do at some <br />point in time contain contaminated water the following steps could be taken: <br />a) Water would be pumped from the wells and contained in a lined evaporation <br />pond or applied to the depository. Since the wells aze completed in fairly low <br />permeability sandstone units, the amount of contaminated water that could <br />potentially flow into the wells would be relatively small, probably less that one <br />gallon per minute. <br />b) The source of the water would be investigated. A trench would be excavated <br />along the northwestern boundary (down gradient) of the depository. The source <br />VOOR I91111915adeliaPmni~l000 doc Sedalia Recycling Center aad Depository <br />
