Contaminated soils found during excavation of soils must be
segregated from clean soil, consolidated, and tested for
disposal. All soil suspected of being contaminated will be placed
on a minimum of 6-mil plastic (or equivalent), and covered by a
minimum of 6-mil plastic. Measures should be taken to prevent any
surface runoff from entering the stockpile, or washing away the
excavated materials. These measures should include constructing
an earthen berm or placing straw bales around the perimeter of
the stockpile to prevent contamination of the surrounding
surfaces. The Contractor will utilize separate stockpiles for
contaminated and clean soil storage. Stockpiles of suspected
contaminated materials shall be completely covered with the
appropriate plastic at all times and secured accordingly.
Parameters and specifications for testing will be dictated by the
disposal facility. If contamination is encountered, the [
Environmental Division should be contacted immediately.
For estimation purposes, the Contractor is not required to assume
Contracting Officer immediately.

environment, as well, specifically to the storm water system. Any
type of spill shall be reported to the Fire Department.
