ENVIRONMENTAL SITE ASSESSMENT SCREENING

PurposeFirst step in ODOT’s ESA ProcessIdentifies all sites in projectUse hard data to screen the project to

determine if site requires Phase I ESA3 types of information collected

◦Regulatory review◦Historical aerial review◦Site Inspection

Regulatory Review

Regulatory Database SearchSearch must have:

◦ NPL/Proposed NPL◦ CERCLIS & CERCLIS-NFRAP◦ CORRACTS◦ RCRA◦ Emergency Response Notification System◦ Landfills◦ BUSTR◦ VAP◦ No Contact List/Fish Advisory

May use commercial database search firm, ODOT GIS or other regulatory databases

Regulatory Database Search, cont.

Mostly concerned with sites within the project

If have the following sites, will often have Phase I ESA for the site regardless if in or out of project◦NPL/Proposed NPL◦CERCLIS/CERCLIS-NFRAP◦CORRACTS◦Other similar sites

Historical Aerials

Historical AerialsMay be obtained from various sources

◦ODOT Office of CADD & Mapping◦Ohio Department of Natural Resources◦Natural Resources Conservation Services◦US Geological Survey◦County Engineer’s Office◦Database Search Firms

Aerial TipsAerials should be high quality

◦Reviewers will enlarge aerial to 200%◦Watch pixelation

Project needs to be markedClearly list date of aerialEnsure you have earliest date possible

◦CADD & Mapping have some from 1938 with full state coverage in the 1950’s

◦Google Earth earliest aerials date to 1992 and can’t be only source

disposal of regulated materials

PhotographsShow the entire site

◦View down the road not necessaryShow the site’s suspect areasIdentify site in captionCaption should provide the direction the

photo was takenIf using geopostitioning camera, provide

map with the direction of the photo

sites◦Request from Prime Consultant or District

ESA Screening Recommendations

Recommendations2 basic outcomes based on all

information◦Phase I ESA◦No further environmental site assessment

warrantedDo not recommend

◦File review◦Plan notes

Recommendations, cont.Gas stations/BUSTR sites will be advanced to

Phase I ESA◦Unless, no ROW and no deep excavation (drive apron,

sidewalks)Electrical transformers

◦Privately owned is a concern since liability is tied to the site

◦Utility owned does not require reporting of the PCB level or additional investigation

◦Utility owned a concern if has apparent release ODOT will notify utility owner to address release

Recommendations, cont.Featureless open railroad track typically

does not warrant additional investigation unless has report or signs of a release ◦May go straight to Phase II ESA

Round houses, sidings, loading/unloading areas, repair areas will require Phase I ESA

ESA Screening Sheet

Site DocumentationMust document all sites in project

◦Residential and agricultural may be present together

Documenting sites by one of methods below◦ESA Screening Sheets◦Table with information contained in ESA
