|
| Note
2: |
Excavated
soil intended for disposal should be placed in an assigned
area with warning posted. Assigned areas are those in
which the general public and site staff cannot readily
gain access. In any event, the soil should be stockpiled
in a safe and effective manner. This requires a proper
setup on an impervious surface with provision to deal
with leachate and runoff properly. The stockpile should
be covered with a plastic sheet to keep off wind and
rain.

|
| Note
3: |
Due
care must be exercised during the transportation of
the excavated contaminated soil to the landfill for
disposal. The soil should be properly contained and
covered to avoid spillage during transport. Suitable
warning signs about the nature of the contaminated soil
should be displayed on both the vehicle and the soil
itself.
|
| |
|
| Note
4: |
A
Remediation Report should be prepared and submitted to
EPD to demonstrate that the clean-up is adequate. Information
such as soil disposal records, sampling results, photographs
and certification of independent checker should be included
in the report. |
