PHASE I ENVIRONMENTAL SITE ASSESSMENT
Site History – Required Information
Aerial PhotographsDetailed 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
1949 Proctorville
1983 Proctorville
Fire Insurance MapsDetailed maps showing potential source
areas, types of activities & location of activities
Maps drawn to 1 inch = 400 feetMay be obtained from commercial search
firm, libraries, historical societies, universities
Ohio Link Media Center site http://www.oplin.org/content/sanborn-maps
1904 Walbridge Park
1936 Walbridge Park
1951 Walbridge Park
City/County DirectoriesLists tenant at the address by yearSources◦Commercial search companies
Dependent on company’s contracts with directories
◦Local libraries◦University libraries◦Historical societies
Site OwnershipList grantee and grantor by year◦List current owner and their grantor first
List transaction dateState land use or lease tenant if providedDo NOT conduct a title search
Site History – Supplemental Information
Property DeedsLeasesSale of USTs system or other equipment
of concernAny environmental liens Deeds to be included in appendices
County Atlases & Plat MapsShows site ownership and property boundariesMay include drawings of exterior of
manufacturing facilitiesPlat maps may contain locations of historic
landfills, manufacturing and commercial activities
Plat maps as maintain by countiesAtlases are available from libraries, counties,
historical societies & database search firmsInclude raw data in appendix
Historical USGS ToposShow site buildings and developmentChanges in elevation on sitesShow mining areasLarge storage locationsInclude raw data in appendix
Property Cards & Tax FilesCurrent and past ownershipAppraisalsMaps/sketches of sitePhotosInclude raw data in appendix
Building PermitsBuilding constructionBuilding modificationEquipment installationEquipment modificationInclude raw data in appendix
Local HistoryLocal historical groups write history of
areaTypically includes discussion of local
businesses Pictures of local businessesInclude raw data in appendix
Regulatory File Review
Regulatory File ReviewDiscussion of a site’s regulatory history◦ Discuss all regulatory records by site and not
by business or parcelObtain files from BUSTR, OEPA and/or
USEPA◦Do not conduct another regulatory database
searchRegulatory database is NOT a substitute
for a regulatory file review unless directed by ODOT
Basic questionsWhat is the site contamination Where is the contamination locatedHas the site delineation been completedAre there any open regulatory issuesWhat are the deed restrictionsIs there an Operation and Maintenance
PlanAre there institutional/engineering
controls
Regulatory File ReviewSoil and groundwater analytical dataMapping showings source areas,
monitoring wells/boring locations, etc.Institutional/engineering controlsSelected remedy Remedial equipment and their locationRCRA ClosuresDocumentation for regulatory issues,
deed restrictions,
Regulatory File ReviewsVAP Phase I, Phase II, Covenant Not Sue,
Operation and Maintenance PlanDocuments 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 agenciesPlace raw data into appendix by site
Interviews
InterviewsCurrent 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 ownerAdjacent tenants and/or property ownersLocal officialsInclude raw data in appendix
Interviews MethodsDuring site reconnaissanceBy phoneMailed questionnaireMay use all 3 for siteDocument interviewee, association with
site, length of time associated with site, and information from interview
If refuses, document attempts and refusal
Site Reconnaissance
Site ReconnaissanceDetailed 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
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
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
Site Reconnaissance of Adjacent Sites
Viewed from subject site or ROWDiscussion should be in relation to
proposed ROWIf 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
Special ItemsESA/NEPA issue only if it is a disposal
issueAsbestos◦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
Mapping
MappingMap showing project locationProvide map locating all Phase I ESA sitesAerials should note the project and the
Phase I ESA sitesSite diagram showing all current and
historical potential source areas and the proposed ROW
Include most current plans
Conclusions & Recommendations
Conclusions & Recommendations
Provided on a site specific basisBased 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
RecommendationsIf 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
Recommendations, cont.Borings/monitoring wells are to be placed
close to potential source areas if possibleRegulated 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
Recommendations, cont.Landfills require a 27-13 permit from
OEPA prior to Phase II ESA, geotechnical investigations and construction
Phase I ESA Updates
Phase I ESA UpdatesDecision 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
