8. PHASE II ENVIRONMENTAL SITE ASSESSMENT WORK PLAN
Phase II ESA Work Plans are prepared only for Major Projects in Step 7. These projects are more
complex and have several alignments under consideration which involve varying amounts of ROW,
type of work and types of structures. The Phase II ESA Work Plan is a separate submission which
documents the site specific recommendations for Phase II ESA work based on the proposed ROW for
the Preferred Alternative for each site of concern noted in the Phase I ESA. Once the Phase II ESA
Work Plan is accepted by ODOT, the Phase II ESA may proceed. Occasionally, some projects will
have a Phase II ESA Work Plan prepared and a Phase II ESA conducted on the Feasible Alternatives
to aid in the selection of the Preferred Alternative.
8.1 Elements of the Phase II ESA Work Plan
8.1.1 Introduction
A discussion of the project location, the nature and purpose of the transportation improvement, and
description of the proposed ROW acquisition for each site should be provided in this section. This
information should be provided by the District Environmental Coordinator or the prime consultant.
In addition, a summary of any previous environmental site assessments of this project (i.e. ESA
Screening, Phase I ESA) should be included in this section. This section should also include a
brief discussion of parcels requiring Phase II ESAs, the rationale, and potential constituents of
concern.
8.1.2 Field Activities and Sampling Procedures
8.1.2.1 Soil Boring/Monitoring Well Locations
The number of soil borings and monitoring wells should be discussed and their locations placed
on a diagram for each site to be investigated in the Phase II ESA. It is preferred that soil
borings be placed in areas of potential concern within the proposed ROW for strip ROW
acquisitions to determine if there is a potential to encounter contaminated materials during
construction. This typically will not require the placement of monitoring wells within the
proposed ROW. 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
