9.1.5.7 Conclusions and Recommendations
Conclusions and recommendations should be based on the data evaluation and interpretation
and details of the proposed transportation improvement. If the analytical test results identify
hazardous substances, then the potential risks associated with the proposed ROW and
construction involving earth disturbing activities must be discussed. Conclusions and
recommendations may involve no further work, additional sampling and testing, the
development of a plan note, or the development of remedial alternatives.
If additional sampling and testing is required, then specific recommendations must be provided
such as sampling and field-screening methods, proposed number and locations of
environmental samples, analytical parameters for chemical analysis, and terminal depth of soil
borings.
9.1.6 Parcel Diagrams
A diagram for each parcel investigated should be included. The diagram should indicate the
sampling locations and potential contamination sources (USTs, drums, sumps, lagoons, etc.) in
relation to the proposed and/or existing ROW limits and proposed work involving earth disturbing
activities (installation of storm/sanitary sewers, foundations for signal poles, catch basins, etc.).
Diagrams are not required to be drawn to scale; however, approximate distances of sampling
locations and potential contamination sources in relation to the transportation project should be
provided (see Appendix H).
There will be situations where a whole take of a site is involved. If this is the case, and if applicable,
a separate map should be included which indicates well elevations, groundwater elevations, bench
marks, and the groundwater flow and potentiometric lines of the groundwater. If soil and/or
groundwater contamination is identified, mapping should be provided which indicates the area and
extent of known contamination, direction of contaminant and/or groundwater flow, and the media
affected based on the data obtained. ODOT will conduct any coordination with the appropriate
regulatory agency as necessary.
9.1.7 Site Specific Health and Safety Plan
It is the consultant's responsibility to determine if a SSHSP (Site Specific Health and Safety Plan)
for Phase II ESA field activities as per 29 CFR 1910.120 is required. The SSHSP is not required to
be included in the Phase II ESA report.
