restoring the area to its original condition at the completion of work. The Contractor shall be responsible for protecting materials stockpiled against weather, damage, theft, and other risks of loss. The USCG assumes no responsibility for material or equipment left in the storage area.

B. Sanitary Facilities: There may not be toilet facilities available for Contractor use at the job site. The

Contractor shall provide his own facilities, including hand washing facilities, in accordance with 29 CFR 1926, Subpart D, paragraph 1926.51 (c) (1) and (f) (1) .]

C. Availability of Utility Services: No commercial utilities are available.

1.17 EXISTING UTILITIES: The existence of any other utility

locations and cable crossings is unknown. The authorized dredge footprint and disposal site are not anticipated to contain underground utilities. The Contractor shall verify all utility and cable crossing locations prior to dredging.

1.18 DRAWINGS: Drawings to be used in conjunction with these

specifications are listed below. The drawings are the property of the Government and shall not be used for any purpose other than that considered by the specification.

The work shall conform to the drawings listed below which form a part of these specifications.

Vallejo (dated October 5, 2022)

ENVIRONMENTAL REGULATORY PERMITS: See section 01 35 43 for more information and the list of appliable permits received for this dredge episode. 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

1.20 responsible for payment of fines resulting from violations of conditions set forth in the above permits.

SEDIMENT ANALYSIS: The material to be removed is material carried along the shoreline by natural currents, wind, and waves. Sampling and analysis were completed for this site in 2023 according to the procedures specified by the

Dredged Material Management Office (DMMO). Sediment analysis results indicated that the proposed dredged materials are suitable for placement at SF-09, Cullinan

Ranch, or the Montezuma Wetlands. DMMO concurred that

Cullinan Ranch is a suitable placement site.

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 outside the limits of permanent work 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 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.

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

D. 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.

E. At or before Contract completion, obliterate all signs of temporary construction facilities such as haul roads, work areas, structures, foundations of temporary structures, stockpiles of excess or waste materials, and all other vestiges of construction. Temporary roads, parking areas, staging areas, and similar temporary use areas where excavation has been accomplished shall be graded in conformance with surrounding areas. Restore all disturbed areas to their original condition.

F. 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. Contractor must have a spill response kit available.

1.06 EROSION AND SEDIMENT CONTROL MEASURES:

A. Borrow pits are not permitted on Government property.

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

C. Provide temporary protection for erodible soils.

1.07

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.

CONTROL AND DISPOSAL OF WASTES: With the exception of 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.

This report will be submitted to the regulatory agencies to satisfy permit requirements. At a minimum, the report will include calculated final dredging volume based on the pre and post dredge surveys, copies of all hydrographic surveys, maps of the dredging footprint, dates of commencement and completion of work, any noncompliance issues, required monitoring logs, environmental permitting compliance documentation, and the disposal location and operations of the dredged sediment. The Post-Dredge Report shall include:

1) Corps permit number.

2) Dredge episode number.

3) Dates of dredging commencement and completion.

4) A survey with accuracy to one-tenth foot that delineates and labels the areas dredged and the dredge depths.

5) Actual quantities dredged to the design depth, and actual quantities dredged to the overdepth limit.

Include calculations used to determine the volume difference (cubic yards) between the pre-dredge and post-dredge surveys and explain any variation in quantities greater than 15% beyond the estimated quantities or dredging deeper than is permitted. All surveys shall be accomplished by a licensed surveyor and signed by the contractor to certify their accuracy.

ARTIFICIAL OBSTRUCTIONS: The USCG anticipates debris such as, but not limited to, metal bands, pallets, pieces of broken cable, rope, hose, and broken piles. The

Government has no knowledge of existing wrecks or wreckages. Prior to dredging, the Contractor shall survey the dredge area and remove debris encountered. Debris removed from the dredge area shall be removed from the water. Explosives shall not be used under any circumstance. Disposal of debris shall be the responsibility of the Contractor and disposal shall be outside the limits of the USCG Station Vallejo property.

QUANTITY OF MATERIAL: The total estimated amount of material to be removed from within the specified limits, including side slopes, is 20,000 cubic yards. The
