Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Section 1506 (b) (3)
Reasons for Exemption
The regulatory scheme for the WETP consists of an approved Remedial Action Plan (RAP) for areas where dredge spoils were historically deposited, and for an outfall area from a discharge pipe associated with a historical waste treatment plant. Both of these areas are hazardous substance release sites, and could be consistent with designation as SWMUS. The RAP specifies cleanup of the outfall area, and cover and institutional controls for the dredge disposal areas.
