Note electrical transformers if owned by site owner Typical for large manufacturing site Becomes an acquisition issue If buildings to be acquired, then they must be accessed and included as part of site reconnaissance Pictures should be taken of all areas of concern and included in the appendix Slide 31 Site Reconnaissance of Adjacent Sites Viewed from subject site or ROW Discussion should be in relation to proposed ROW If site was investigated as part of ESA Screening and was not advanced to Phase I ESA or a Phase I ESA is being conducted, do not provide a detailed discussion of the site Slide 32 Special Items ESA/NEPA issue only if it is a disposal issue Asbestos Discuss if potentially asbestos containing material has been disposed of on a site Wrapped utility pipe laying underneath bridge Lead paint Paint chips or black sand (Black Beauty) found on ground Slide 33 Mapping Slide 34 Map showing project location Provide map locating all Phase I ESA sites Aerials should note the project and the Phase I ESA sites Site diagram showing all current and historical potential source areas and the proposed ROW Include most current plans Slide 35 Conclusions & Recommendations Slide 36 Provided on a site specific basis Based on detailed historical use, current use and regulatory information and the amount of proposed ROW For historical BUSTR sites, document last apparent use of USTs If use discontinued after November 8, 1984 considered orphan tank Slide 37 Recommendations If Preferred Alternative has not been selected, will go to Phase II ESA Work Plan Recommended sites for Phase II ESA by alterative but do not provide site specific sampling and testing recommendations If Preferred Alternative has been selected, include number and location of soil borings/monitoring wells, analytical testing, in relation to the proposed ROW Slide 38 Recommendations, cont. Borings/monitoring wells are to be placed close to potential source areas if possible Regulated sites that have been previously investigated typically are not advanced to Phase II ESA Plan notes may be recommended based on analytical from regulatory file Compare analytical to BUSTR PCS reuse levels or VAP residential levels Do not recommend soil reuse for a site Dont know if additional soils needed for project Slide 39 Recommendations, cont. Landfills require a 27-13 permit from OEPA prior to Phase II ESA, geotechnical investigations and construction Slide 40 Phase I ESA Updates Slide 41 Decision for Phase I ESA Update is project specific Not dependent on AAI tame limitations District requests determination from OES- ESA Unit Districts monitors projects and notifies the ESA Unit if there have been significant changes Slide 42 QUESTIONS?
