The project shall adhere to Section 307 of the Coastal Zone Management Act, the U.S. Fish and Wildlife Service and National Marine Fisheries Service, Section 7 of the Endangered Species Act, Marine Mammal Protection Act, and Magnuson-Stevens Fisheries Conservation and Management Act. Copies of the environmental permits provided as an Attachment.

The terms and conditions, best management practices, and avoid measures include, but are not limited to, turbidity monitoring, solid debris management, spill prevention plans, etc.

The Contractor shall comply with all requirements under terms and conditions set forth in the environmental permits and authorizations issued for this project.

Copies of these environmental permits are provided with these specifications as Appendix A. The Contractor shall familiarize personnel with these, and any other permits issued for this project and comply with all requirements under the terms and conditions set forth therein. The contractor will be responsible for payment of fines resulting from violations of conditions set forth in the above permits.

B. Preserve the natural resources within the project boundaries and within the vicinity of performed under this Contract in their existing condition or restore to an equivalent or improved condition upon completion of the work. Repair or restore to original condition landscape features scarred or damaged by equipment or

10597026 01 35 43 Page 22 operations. Obtain Contracting Officer's approval before repair or restoration. Confine construction activities to areas defined by the work schedule, drawings, and specifications. Federal Acquisition Regulation clause 52.236-9 applies.

All project activities must be executed in compliance with the 2015 Biological Opinion (BiOp) for the Long Term Management Strategy for the Placement of Dredged Material in the SF Bay Region. These conservation measures include:

1) Compliance with environmental work windows.

2) Best practices for all dredgers (minimize dredging and disposal, minimize impacts of dredging, minimize impacts of disposal)

3) Best practices for hydraulic dredging if used. See BiOp, Section 1.3.4 at San Francisco District > Missions > Dredging Work Permits > LTMS.

C. Eelgrass Vegetation: An eelgrass survey was conducted in June 2024 (WRA, Inc 2024) to identify eelgrass within the vicinity of the proposed dredge area. The eelgrass survey identified approximately 4,057 square meters of eelgrass vegetation located north of the project area along the shoreline and within 250 meters of the dredging footprint. Most of the observed vegetated eelgrass habitat formed one large, continuous bed located parallel to the shoreline northeast of the USCG pier and dock facilities. Some additional, isolated eelgrass patches were detected immediately south and east of the primary bed. In addition, a total of 831 square meters of macroalgae was observed along the shoreline, between the rip-rap shoreline and the eelgrass bed.

According to this eelgrass survey, proposed dredging activities could directly disturb eelgrass along the shoreline and may also have the potential to indirectly disturb this patch of eelgrass with increased turbidity, which eelgrass is extremely sensitive to.

Eelgrass surveys shall be conducted prior to and post dredging (see Section 1.06, below). Vessel operators will not drop anchors/spuds within identified eelgrass beds.

Further, a 10-foot buffer around eelgrass beds will be maintained by vessel operators and dredge equipment. The https://www.spn.usace.army.mil/missions/dredging-work-permits/ltms/ https://www.spn.usace.army.mil/missions/dredging-work-permits/ltms/

10597026 01 35 43 Page 23 attached Water Quality Certification permit includes direction for monitoring turbidity. If turbidity increases beyond what is allowable is detected, all work will stop. If best management practices do not prevent further disturbance to the ecosystem, the Contractor shall deploy a full-depth turbidity curtain surrounding the work area to minimize the effects of suspected sediments to nearby eelgrass bed.

D. Except in areas indicated to be cleared, do not remove, cut, deface, injure, or destroy vegetation without special written permission from the Contracting Officer.

E. Construction equipment is to be kept in good repair, without leaks of hydraulic or lubricating fluids. If such leaks or drips do occur, they shall be cleaned up immediately. Drip pans shall be utilized when vehicles are parked. Confine equipment maintenance and/or repair to one location. Control runoff in this area to prevent contamination of soils and water.

F. At or before Contract completion, temporary construction facilities such as stockpiles of excess or waste materials and all other vestiges of construction. Restore all disturbed areas to their original condition.

G. For all work in or over water habitats, provide a debris boom. Take precautions to preclude construction materials from entering the water and immediately remove any material that enters the water in the work area. Report spills of any liquids into the water habitat and take steps to preclude spread or dissipation of spilled liquids.

H. The Contractor shall maintain an adequate spill response kit (including absorbent pads and floating oil containment booms) on the primary dredge vessel and support tugboat. All hydraulic hoses must be maintained to prevent leaks. In the event of a petroleum spill, the Contractor must immediately deploy containment booms, notify the USCG COR, and contact the National Response Center (NRC).

1.06 EELGRASS PROTECTION: Water quality monitoring and

turbidity controls (e.g., silt curtains) are required to protect existing eelgrass beds in the area surrounding the dredge footprint. Controls at in-water disposal sites

10597026 01 35 43 Page 24 are not required and compliance shall be verified solely through the Dredging Quality Management (DQM) GPS tracking system as outlined in the DOP to be included in the post-dredge report.

A. Visual Monitoring: The Contractor shall conduct regular visual monitoring of the water surface during all active dredging operations.

1) Observations shall be made immediately exterior to the deployed silt curtain.

2) Observations shall be made during every scow loading event and at a minimum of every 1 hour during dredging actions.

3) If any plumes are identified escaping the containment area, the Contractor shall immediately cease dredging, notify the COR, and document the event and corrective actions taken for the daily report.

4) Daily reports shall include a log of all visual observations with verification that the entire relevant length of silt curtain was observed.

B. Physical Containment: As mandated by the environmental permits to protect adjacent eelgrass habitats, the Contractor shall deploy and maintain a full-depth curtain (silt curtain) surrounding any active dredging operation.

The silt curtain must be:

1) Properly deployed prior to the commencement of any dredging.

2) Rated for the tidal currents of the San Francisco Bay and installed in a manner that prevents the escape of suspended sediments from the dredge footprint.

3) Enclose the entire work area, generally no less than 50 feet and no more than 100 feet from the active dredge footprint.

4) Avoid proximity to existing eelgrass bed. Anchors and ballast chains shall not be allowed to drag across known eelgrass habitat.

C. Instrumental Monitoring: If visual observations indicate persistent failure of the silt curtain, or if directed by

10597026 01 35 43 Page 25 the RWQCB, the Contracting Officer may require the Contractor to implement formal, instrumented (metered) turbidity monitoring at no addition cost to the Government.

D. Eelgrass Surveys: The Contractor shall perform eelgrass surveys to determine the presence of eelgrass (Zostera marina and Zostera pacifica) within the dredge footprint and surrounding area, and to provide a comparative and quantitative assessment of the eelgrass communities within the area of potential effect prior to, and after dredging. The surveys shall be conducted in conformance with the requirements of both the California Eelgrass Mitigation Policy (CEMP) (NOAA 2014) and Eelgrass/Macroalgae Habitat Interim Survey Guidelines (WDFW 2008). The eelgrass surveys shall use a 45-meter and 250-meter buffer area outside of the dredge footprint perimeter. The report shall include calculated square meters of eelgrass in the project and buffer areas; a map that clearly show the location(s) of any eelgrass beds;

and a brief discussion of the survey methods, survey results relative to the survey parameters (spatial distribution, aerial extent, percent vegetated cover, and turion density), observation of invasive species (caulerpa sp.), and recommendations. Raw data shall also be included in the report.

Submit the name and qualifications of the Firm that will conduct the eelgrass surveys for approval prior to the kickoff meeting.

1) The pre-dredge eelgrass survey shall be performed as soon as possible and no later than 30 days after award and shall record all presence of eelgrass (eelgrass density and eelgrass extent). Dredging cannot be initiated until after the survey has been completed.

2) A post-dredge eelgrass survey shall be completed within 5 days after completion of dredging and shall document the presence/absence of eelgrass and any potential effects from the dredging operations. The results of the eelgrass surveys shall be submitted in report form no later than 25 days after completion of work.

1.07 EROSION AND SEDIMENT CONTROL MEASURES:

A. Borrow pits are not permitted on Government property.

10597026 01 35 43 Page 26

B. Provide necessary controls to prevent visible or measurable erosion from leaving the construction site.

C. Provide temporary protection for erodible soils.

Immediately protect side slopes and back slopes upon completion of rough grading. Plan and conduct all earthwork to minimize duration of exposure of unprotected soils.

1.08 CONTROL AND DISPOSAL OF WASTES: Apart from materials

specifically indicated or specified to be salvaged for reuse in construction, or turned over to the Government, all wastes and demolished materials become the contractor's property and shall be removed from the job site daily.
