ENVIRONMENTAL SITE ASSESSMENT SCREENING
2
Purpose First step in ODOT’s ESA Process Identifies all sites in project Use hard data to screen the project to determine if site requires Phase I ESA 3 types of information collected ◦ Regulatory review ◦ Historical aerial review ◦ Site Inspection
3
Regulatory Review
4
Regulatory Database Search Search 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
5
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
6
Historical Aerials
7
May 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
8
Aerial Tips Aerials should be high quality ◦ Reviewers will enlarge aerial to 200% ◦ Watch pixelation Project needs to be marked Clearly list date of aerial Ensure 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
9
Items to Note Land use Areas of excavation Storage or disposal areas Drums Tanks, tank pits and pump islands Any other suspect uses or items
10
Findlay 1947
12
Site Inspection
13
Site Inspection Items to Note Evidence of current and/or former UST system Disturbed soils and/or damaged vegetation Drum (contents and number) Waste Ponds/lagoons Odors Other signs of treatment, storage or disposal of regulated materials
14
Photographs Show the entire site ◦ View down the road not necessary Show the site’s suspect areas Identify site in caption Caption should provide the direction the photo was taken If using geopostitioning camera, provide map with the direction of the photo
15
Site 2, Vacant Building, 117 Oak Park Drive, facing east
16
Geopositioning Camera Site 2, Vacant Building, 117 Oak Park Drive
18
Optional Information Sanborn Maps ◦ May be appropriate for non-typical projects Regulatory Files ◦ Requirement of Phase I ESA Property Cards ◦ Optional for Phase I ESA
19
Mapping All mapping/aerials must show project USGS Topo with project area County and/or city road maps Historical aerial photographs Preliminary Plans – show locations of sites ◦ Request from Prime Consultant or District Oil/Gas Wells – If oil/gas wells in project Sanborn maps - optional
20
ESA Screening Recommendations
21
Recommendations 2 basic outcomes based on all information ◦ Phase I ESA ◦ No further environmental site assessment warranted Do not recommend ◦ File review ◦ Plan notes
22
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
23
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
24
ESA Screening Sheet
25
Site Documentation Must 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 Screening sheer Typically used for large projects
26
Name of preparer Preparer title Date prepared District # LUC-75-3.9977254 Short description of project Tenant name and address they use for site
27
Provide current use and what they do – Joe’s Place, Auto Repair Past use – gas station, landfill For site Near by NPL, CERCLIS, & RCRA CORRACT sites
28
From Site Inspection Number and content of USTs/ASTs & Drums Photo ID’s of site
