  1. Phase I Environmental Site Assessment

  2. Site History – Required Information

  3. Aerial Photographs • Detailed site specific review and discussion • Identify land use and site configuration • Potential sources of contamination • Areas of excavation • Drum storage • UST system, pumps islands • Changes to streams • Other suspect areas

  4. 1949 Proctorville

  5. 1983 Proctorville

  6. Fire Insurance Maps • Detailed maps showing potential source areas, types of activities & location of activities • Maps drawn to 1 inch = 400 feet • May be obtained from commercial search firm, libraries, historical societies, universities • Ohio Link Media Center site http://www.oplin.org/content/sanborn-maps

  7. 1904 Walbridge Park

  8. 1936 Walbridge Park

  9. 1951 Walbridge Park

  10. City/County Directories • Lists tenant at the address by year • Sources • Commercial search companies • Dependent on company’s contracts with directories • Local libraries • University libraries • Historical societies

  11. Site Ownership • List grantee and grantor by year • List current owner and their grantor first • List transaction date • State land use or lease tenant if provided • Do NOT conduct a title search

  12. Site History – Supplemental Information

  13. Property Deeds • Leases • Sale of USTs system or other equipment of concern • Any environmental liens • Deeds to be included in appendices

  14. County Atlases & Plat Maps • Shows site ownership and property boundaries • May include drawings of exterior of manufacturing facilities • Plat maps may contain locations of historic landfills, manufacturing and commercial activities • Plat maps as maintain by counties • Atlases are available from libraries, counties, historical societies & database search firms • Include raw data in appendix

  15. Historical USGS Topos • Show site buildings and development • Changes in elevation on sites • Show mining areas • Large storage locations • Include raw data in appendix

  16. Property Cards & Tax Files • Current and past ownership • Appraisals • Maps/sketches of site • Photos • Include raw data in appendix

  17. Building Permits • Building construction • Building modification • Equipment installation • Equipment modification • Include raw data in appendix

  18. Local History • Local historical groups write history of area • Typically includes discussion of local businesses • Pictures of local businesses • Include raw data in appendix

  19. Regulatory File Review

  20. Regulatory File Review • Discussion of a site’s regulatory history • Discuss all regulatory records by site and not by business or parcel • Obtain files from BUSTR, OEPA and/or USEPA • Do not conduct another regulatory database search • Regulatory database is NOT a substitute for a regulatory file review unless directed by ODOT

  21. Basic questions • What is the site contamination • Where is the contamination located • Has the site delineation been completed • Are there any open regulatory issues • What are the deed restrictions • Is there an Operation and Maintenance Plan • Are there institutional/engineering controls

  22. Regulatory File Review • Soil and groundwater analytical data • Mapping showings source areas, monitoring wells/boring locations, etc. • Institutional/engineering controls • Selected remedy • Remedial equipment and their location • RCRA Closures • Documentation for regulatory issues, deed restrictions,

  23. Regulatory File Reviews • VAP Phase I, Phase II, Covenant Not Sue, Operation and Maintenance Plan • Documents showing no additional investigation/remedial work required by regulatory agency • Other information as appropriate for the site from the regulatory file • May include files from local agencies • Place raw data into appendix by site

  24. Interviews

  25. Interviews • Current tenant • Conducted with current store/business manager for the site • Because site owned by large corporation that doesn’t respond to mailed questionnaires is not an excuse to skip the owner/tenant interview • Current property owner • Adjacent tenants and/or property owners • Local officials • Include raw data in appendix

  26. Interviews Methods • During site reconnaissance • By phone • Mailed questionnaire • May use all 3 for site • Document interviewee, association with site, length of time associated with site, and information from interview • If refuses, document attempts and refusal

  27. Site Reconnaissance

  28. Site Reconnaissance • Detailed inspection of site for evidence of contamination and/or potential contamination • Property owner notification highly recommended • If access to site denied, contact DEC • ODOT will obtain access or provide direction for the site • Required for whole takes

  29. Site Reconnaissance, cont. • Note locations of potential contamination such as: • UST systems • Drum/battery storage, number and drum contents or type of batteries • All other chemical storage areas with chemicals specified, number of containers, their contents and amounts • Monitoring wells/apparent soil borings • Disposal areas • Areas where chemicals are used • Oil/gas wells

  30. Site Reconnaissance, cont. • 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

  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

  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

  33. Mapping

  34. Mapping • 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

  35. Conclusions & Recommendations

  36. Conclusions & Recommendations • 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

  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

  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 • Don’t know if additional soils needed for project

  39. Recommendations, cont. • Landfills require a 27-13 permit from OEPA prior to Phase II ESA, geotechnical investigations and construction

  40. Phase I ESA Updates

  41. Phase I ESA Updates • 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
