4. RED FLAG SUMMARY<br />

A Red Flag Summary – ESA Section is typically performed during Step 1 <strong>of</strong> the Minimal and Minor<br />

Projects and Step 2 in the Major projects <strong>of</strong> the PDP for projects.<br />

The purpose <strong>of</strong> a Red Flag Summary is to identify and locate major areas <strong>of</strong> known environmental<br />

concern for hazardous wastes within the study area that may influence or control the development <strong>of</strong><br />

the corridors (i.e. through avoidance, minimization, or remedial activities). Databases maintained by<br />

USEPA, OEPA, and health agencies must be researched and ground-truthed to confirm the sites are<br />

within the study area. Each site is then identified and located on a map <strong>of</strong> the study area.<br />

<strong>Environmental</strong> database companies are typically contracted to conduct the database search. <strong>Site</strong>s<br />

which are <strong>of</strong> concern include Superfund sites, sites on the NPL (National Priority List) and CERCLIS<br />

list, sites on the <strong>Ohio</strong> Master <strong>Site</strong>s List, former or current landfills, sites undergoing RCRA closure,<br />

RCRA large quantity generators, RCRA TSDs (Transportation, Storage, and Disposal facilities) and<br />

large industrial sites. The Red Flag Summary also assists in the development <strong>of</strong> realistic project<br />

schedules for projects that involve these types <strong>of</strong> sites.<br />

The database information obtained during the Red Flag Summary can be used for the ESA process<br />

(i.e. in the ESA Screening). However, keep in mind that the ESA Screening will involve other activities<br />

in addition to obtaining database information. The Red Flag Summary is not the first step in the<br />

environmental site assessment process and is not used to determine if environmental site assessment<br />

is conducted on a project.<br />

The mapping <strong>of</strong> all identified sites on study area base mapping and identification <strong>of</strong> each site with the<br />

source <strong>of</strong> the regulatory listing must be provided. A discussion <strong>of</strong> sites that can potentially influence or<br />

control the development <strong>of</strong> the project should be included and provided with the study area exhibit.<br />

For a more detailed discussion on the Red Flag Summary, including the search radii, please refer to<br />
