In addition to the area disturbed as a result of the release, additional acreage was impacted by the cleanup activities, including moving cleanup equipment, building a sedimentation lagoon (to store sediments dredged from Liod Re n Creek creatind )an soiga l pile. Although the majority of spilled materials were recovered immediately following each event, residuals remai bot n wetlandne i limitehn th i d sdan area uplanf so d soils. Several alternatives have been proposed in the Feasibility Study to remediate the impacts to affected sediments and soils. These include: excavation followed by varying degrees of treatment and stabilization prior to emplacement in an on-site impoundment; excavation followed by low temperature thermal desorption treatef o e ;dus soil backfillr sfo in-sitd ;an u biological treatment. Each of these alternatives, with the exception of "no action", involves excavation and ground disturbing activities that could impact upon cultural properties located within the twenty- five acre site.
