5. ENVIRONMENTAL SITE ASSESSMENT SCREENING The Environmental Site Assessment (ESA) Screening is conducted on Minor Projects during Step 1 for all alternatives under study and in Step 5 for Major Projects for all conceptual alternatives. The intent of the ESA Screening is to identify all parcels within a study area and provide sufficient investigation to develop a list of suspect properties which require Phase I ESA. Gathering and reviewing present day and some historic land use information, as well as regulatory databases, is the primary focus of the ESA Screening. Additional information such as significant physical characteristics of the study area and project history should also be included in the ESA Screening. All properties within the project study area are screened at this level. Although an ESA Screening does not imply a need to enter a property which may be contaminated with hazardous substances, some level of field reconnaissance will be necessary to verify the database information. The ESA Screening process notes potential sources of contamination. This visual inspection should be conducted from existing public right of way or through normal project field reviews. The following outline identifies the elements of the ESA Screening report along with several sources of information which should be reviewed; however, it does not preclude the use of other pertinent information such as ESA Screening Checklists and supportive information such as historical aerial photographs, project plan sheets, copies of regulatory records, and/or photographic logs. 5.1 Elements of the ESA Screening 5.1.1 Executive Summary The executive summary is a portion of the report which provides a summary of the transportation project and the findings of the ESA Screening. The executive summary is generally one page in length and should include a listing of the properties recommended for additional investigation. 11
5.1.2 Introduction An introduction should be provided which discusses the proposed transportation project and other relevant information such as the physical setting of the project and overall land use of the area. It is not necessary to provide more than a brief discussion of the physical setting. The introduction should include a description of the proposed transportation project and a general discussion of the improvements to the facility or transportation system (i.e., the number of lanes to be added, any drainage features to be added or modified, etc.) 5.1.3 Mapping Mapping must be included which clearly delineates the project study area or corridor and specifically identifies commercial, industrial, or any other properties or activities which may pose an environmental concern. The following maps must be included in the report as a minimum: USGS (United States Geological Services) Topographic Quadrangle Maps - These maps are published by the USGS which provide information such as local topography, drainage, roads and other land uses which were active at the time of mapping. Topographic maps are to be presented in the correct scale. If the consultant wishes to provide an enlarged topographic map, this is to be in addition to the copy at the correct scale. These maps are available for sale in 7.5 minute quadrangle at several organizations including ODNR (Ohio Department of Natural Resources) and ODOT-Office of Aerial Engineering (see Appendix C). County and/or City Road Maps - These maps include roads, municipalities and other features in the study area. Aerial Photography - Aerial photographs provide information about current and past land uses and potential source areas of contamination. Aerial photographs for several different periods should be obtained and reviewed to identify land use changes. At a minimum, a cursory review and discussion is required. Aerial photographs are available through ODOT (through the Office of Aerial Engineering; aerials are available on print(s) or as JPEG and TIFF files on CD(s)), ODNR (Ohio Department of Natural Resources), NRCS (Natural Resources Conservation Service), USGS (United States Geological Survey), County Engineer's Office, and local planning organizations. These sources often have aerial photographs dating to the late 1930’s. These are the preferred sources for aerial photographs. The lack of historical aerials from a 12

An introduction should be provided which discusses the proposed transportation project and other<br />
relevant information such as the physical setting <strong>of</strong> the project and overall land use <strong>of</strong> the area. It<br />
is not necessary to provide more than a brief discussion <strong>of</strong> the physical setting. The introduction<br />
should include a description <strong>of</strong> the proposed transportation project and a general discussion <strong>of</strong> the<br />

5.1.3 Mapping<br />
Mapping must be included which clearly delineates the project study area or corridor and<br />
specifically identifies commercial, industrial, or any other properties or activities which may pose an<br />
environmental concern. The following maps must be included in the report as a minimum:<br />
USGS (United States Geological Services) Topographic Quadrangle Maps - These maps are<br />
