Remarks:

1

For metal contaminants (except Copper) to be treated by solidification, the Universal Treatment Standards (UTS) of

U.S. Resource Conservation and Recovery Act (RCRA) wastes that contain metals (in 40 CFR 268) are referred.

2

For Copper, please refer to the section "Mitigation for Land Contamination" of the Final EIA Report for the details of

the derivation of this value.
