1.3 CONTRACTOR PERFORMANCE EVALUATIONS

In accordance with the provisions of Subpart 36.201(Evaluation of Contractor Performance) of the Federal Acquisition Regulation (FAR), construction contractor's performance shall be evaluated throughout the performance of the contract. The United States Army Corps of Engineers (USACE) follows the procedures outlined in Engineering Regulation 415-1-17 to fulfill this FAR requirement. The USACE uses the web-based Construction Contractor Performance Assessment Reporting System (CPARS) to document contractor's performance and prepare performance reports. After an evaluation (interim or final) is written up by the USACE, the Contractor may access, review and comment on the evaluation for a period of 30 days.

Accessing and using CPARS requires Public Key Infrastructure (PKI) certification. The certification is a Department of Defense requirement and was implemented to provide security in electronic transactions. This certification is purchased from an External Certificate Authorities (ECA) vendor. Contractor access to CPARS is required for Contractor participate in the performance evaluation process. PKI certification is required for Contractor access to CPARS. PKI certification is the sole responsibility of the Contractor. Current information about the PKI certification process and known PKI vendors can be found on the web site: http://www.cpars.gov/.

1.4 PERMITS

The Contractor shall obtain and comply with all licenses and permits required by Federal, State, and local laws, codes, and regulations unless otherwise specified in these contract documents.The Government has provided the requirements of (1)The Memorandum of Understanding (MOU) of the California Regional Water Quality Control Board,(2) The Central Valley Regional Water Quality Control Board Waste Discharge Requirements for Maintenance Dredging Operations Order R5-2022-0052 (WDR),(3)The Fisheries Service (NMFS) Stockton Deep Water Ship Channel Biological Opinion (2016-2025),(4)The United States Fish and Wildlife Service (USFWS) Stockton Deep Water Ship Channel Biological Opinion (2023-2028). The Contractor shall comply with these requirements and provisions in these contract specifications included in Sections TEMPORARY ENVIRONMENTAL CONTROLS 01 57 19 and DREDGING 35 20 23.

1.5 PUBLIC SAFETY

The Contractor shall provide guard personnel as required to provide protection in the interest of public safety. Whenever the Contractor's operations create a condition hazardous to the public, he shall furnish at his own expense and without cost to the Government, such guards as are necessary to give adequate warning to the public of any dangerous conditions to be encountered, and he shall furnish, erect, or maintain such lights, signs and other devices as are necessary to prevent accidents and to avoid damage or injury to the public. Flagmen and guards, while on duty and assigned to give warning to the public that the dredging is being

SECTION 01 11 00 Page 3 May 06, 2024 extent feasible.

(7) If significant damage to wetlands or associated vegetation occurs, the Contractor shall restore the area to pre-existing conditions.

(8) The contractor is responsible for providing erosion and sediment control measures in accordance with Federal, State, and local laws and regulations to ensure compliance with water quality standards. The Contractor is responsible for the placement of temporary and permanent erosion and sediment control best management practices. These may include, but are not limited to, vegetation cover, stream bank stabilization, slope stabilization, silt fences, construction of terraces, interceptor channels, sediment traps, inlet and outfall protection, diversion channels, and sedimentation basins. Silt fences and other non-natural temporary measures shall be removed after the area has been stabilized.

1.4.2 Additional Conservation Measures for the Protection of Aquatic Resources for Cutterhead Dredgers

(1) If using a cutterhead dredger, the cutterhead will not be operated more than three feet above the channel bottom.

(2) Suction will not be employed while the dredge head is deployed and retrieved through the water column.

(3) The dredger will maintain the suction head at a constant elevation near the channel bed when dredging, to reduce the field of influence where fish may be entrained into the dredge pipe.

(4) Draghead deflectors will be installed on the leading edge of hopper dredge dragheads to minimize the risk of incidental take of benthic species such as green sturgeon. The deflector is designed to have a plowing effect of at least 6 inches.

1.4.3 Additional Conservation Measures for the Protection of Aquatic Resources for Clamshell Dredgers

(1) Multiple horizontal dredge cuts will be taken where a thick horizontal volume needs to be dredged to avoid overfilling the bucket and causing spillage.

(2) Once the clamshell bucket reaches the target depth, it will be fully closed before the dredge operator begins to raise it to the surface of the water column. This method, coupled with the use of a mechanical cable arm environmental clamshell bucket, minimizes the potential for generating turbidity in the water column.

(3) Once out of the water, the clamshell bucket will place dredged sediment directly into the scow. Sediment will not be released from the bucket until it is fully inside the scow. Within the scow, dredged sediment will pass through a 12-inch-by-12-inch grid to prevent any solid debris or artificial objects from entering the scow. Solid debris and artificial objects trapped on the grid will be removed and brought to an approved waste disposal site. Large woody debris with environmental value will be returned to the channel where not a hazard to navigation. The bucket will be held open over the grid within the scow until all the sediment and water has drained from within it to minimize the potential for resuspension of the sediment in the water

SECTION 01 57 19 Page 8 May 06, 2024 column.

(4) The load line on disposal barges used for mechanical dredging will be predetermined based on channel conditions, and the barge will not be filled above this predetermined level. Under no circumstance will scows be loaded to more than 90% capacity.

(5) Untreated water shall not be overflowed, decanted, discharged, or otherwise released from the vessel.

(6) Before each disposal barge is transported to a placement site, the dredging contractor and a site inspector must certify that it is filled correctly. Scows will be inspected to ensure no loss of sediment during loading and transport.

(a) If turbidity levels reach a value that represents 75% of the relevant allowable limit as identified in the MOU or WDR for any reason, the Corps' contractor will immediately slow the dredge rate by 50% to prevent turbidity levels from increasing further (i.e., if the cycle time for the bucket to descend, collect material, and drop that material in the scow is 30 seconds when the violation occurs, the revised cycle time should be 45 seconds until levels return to below 75% relevant allowable limits).

(b) If turbidity levels reach a value that represents 90% of the relevant allowable limit as identified in the MOU or WDR for any reason, the Corps' contractor will deploy a type II turbidity curtain, bubble curtain, or other similar measure to prevent the plume from migrating away from the dredge site. The curtain shall remain in place until levels have returned to below 75% relevant allowable limits.

1.5 SPECIAL ENVIRONMENTAL REQUIREMENTS

The Contractor shall conduct dredging, material placement, and any discharge of decant water from dredged material placement sites in accordance with (1)The Memorandum of Understanding (MOU) of the California Regional Water Quality Control Board,(2) The Central Valley Regional Water Quality Control Board Waste Discharge Requirements for Maintenance Dredging Operations Order R5-2022-0052 (WDR),(3)The Fisheries Service (NMFS) Stockton Deep Water Ship Channel Biological Opinion (2016-2025),(4)The United States Fish and Wildlife Service (USFWS) Stockton Deep Water Ship Channel Biological Opinion (2023-2028).

Biological Opinions (BOs) and associated Addendums of U.S. Fish and Wildlife Service (USFWS) and National Oceanic and Atmospheric Administration (NOAA). The contractor is responsible for maintaining regular communication to its fish and water quality monitoring staff regarding when and where dredging and material placement will be occurring, when discharge from dredged material placement sites will begin and end, if there are any unexpected discharges, etc. The contractor shall give the monitoring staff as much notice of these items as possible.
