Environmental Site Assessment Guidelines - Ohio Department of ...

9.1.8 Environmental Plan Notes
If the Phase II ESA has determined that hazardous substances and/or petroleum contaminated
soils will be encountered during construction, then the Phase II ESA recommendation may be to
develop an environmental plan note to place in the construction plans. The plan note describes the
management of these materials during construction and is incorporated into the construction
contract. Environmental plan notes will not be developed as part of the Phase II ESA activities and
are developed at a later date (i.e. once detailed design information is available). The ODOT ESA
Unit can be contacted for guidance on developing these plan notes.
9.1.9 Remedial Design
If the Phase II ESA determines that acquisition of a contaminated parcel of land is necessary for
highway development, then a Phase II ESA recommendation may be to prepare a remedial design
to ensure that contaminated media is remediated and/or managed in a manner which is consistent
with the appropriate environmental regulations. In short, remedial design will consist of a set of
instructional statements, including any applicable drawings both of which should be prepared in
standard ODOT construction contract format instructing a contractor on how to execute the
remedial effort. This is typically developed at a later date and outside of the environmental site
assessment process. A remedial design may involve developing a stand-alone contract that is
separate from a roadway construction contract. Remedial design can range from a typical
underground storage tank removal to a situation as complex as a large scale remediation plan (i.e.
groundwater treatment system). A consultant involved with remedial design must be pre-qualified
with ODOT's Office of Contracts.
9.1.10 Investigation-Derived Waste
All wastes generated during Phase II ESA investigations will be managed and disposed of as per
ODOT's Revised Guidance Regarding the Management of Investigation-Derived Waste (see
Appendix K).
9.2 Reporting Requirements
The title page of the Phase II ESA report must contain ODOT's project identification including the
county, route, and section as well as the PID for the project. The introduction of the report should
include all background information, including project information and a summary of previous
environmental site assessments. The signature page should indicate the primary author.
