Dredged material shall be removed using a mechanical clamshell dredge and transported by barge to be permanently disposed of at an appropriate placement site. Suitable dredged material may be placed at an in- Bay site such as Alcatraz Island Dredged Material Disposal Site (SF-9), at a permitted beneficial reuse site, or at an appropriate authorized upland location.

The contractor is expected to mobilize for pre-dredge hydrographic survey as soon as possible and produce a Dredge Operations Plan (DOP) within 30 days of award (to include the surveys). The contractor shall begin dredging as soon as a notice to proceed is received following approval of the DOP, while implementing requirements and best practices identified in the attached permits to minimize impacts to federally listed species and protected habitat.

A. All in-water work must be completed during the in-water work window (IWWW) of August 1 to November 30 to minimize impacts on Environmental Safety Act (ESA) protected fish species per BCDC Permit No. C2007.005.07, (BCDC Permit) Special Condition II-I.

B. Dredged sediment shall be permanently disposed of using a bottom dump barge. As part of the Long Term Management Strategy (LTMS) for placement of dredged material in the San Francisco Bay Region, the volume disposed of for the work described herein shall be limited by site per the Clean Water Act Section 401 Water Quality Certification and Order WDID # 2 CW455657 (Section 401). In-Bay disposal shall not exceed 20% of total dredged material.

Approved upland beneficial reuse sites shall receive no less than 62% of the total dredged material so long as the material dredged is suitable for upland placement.

The remaining dredged material shall be disposed of at approved ocean or upland sites.
