Environmental Site Assessment Guidelines - Ohio Department of ...

B.
All recommended soil borings must be advanced within the proposed ROW (right-of-
way). Monitoring wells are not typically warranted for strip takes. In the event there
is no proposed ROW, sampling must be conducted within the existing ROW. In
general, sampling locations and depth of soil borings are dependent upon the
potential sources of contamination and, if available, upon the proposed depth of
construction. In some instances, proposed depth of borings may be in accordance
with or based on regulations from BUSTR or OEPA.
Where the whole property will be acquired, not only will the potential to encounter
contaminated materials be assessed, but also the liabilities of acquiring the source
areas on the property for the project. This will typically require the placement of soil
borings and monitoring wells on the property.
Major Projects
For Major Projects, general Phase II ESA recommendations should be provided such
as the site names and addresses, the alignment the site is in, types of potential
contaminants, presence of any ground water problems, etc. Once the preferred
alternative is selected, a Phase II ESA Work Plan consisting of site-specific Phase II
ESA recommendations will be prepared for that alternative. Hence, the Phase II ESA
will be conducted after the preferred alternative has been selected and the Phase II
ESA Work Plan is accepted. However, it should be recognized that in some cases,
the Phase II ESA may be performed on multiple alternatives to aid in selecting the
preferred alternative.
