If the dredge is outside the dredge area limits, the Contractor shall provide reason the dredge is outside the dredge area limits such as turning around annotated on the position chart and the dredge depth within 1-foot accuracy. Add notation in the Contractor's Quality Control Report for each occurrence.

3.3.3 Hopper Dredge/Scow

A hopper dredge or barge with pump-out capabilities may be used for transport of the excavated material. Overflow at the dredge site during loading will be permitted to the extent that turbidity and water quality standards required by Sections 01 57 20 ENVIRONMENTAL PROTECTION and 01 57 25 TURBIDITY AND DISPOSAL MONITORING are met. No overflow is permitted within 120 meters of cultural and hardbottom resources or anywhere outside the dredge area. The Contractor shall limit the loading to partial loads, if necessary, to meet turbidity and water quality requirements permitted at the dredge site. No overflow or spillout will be permitted during transport to the discharge site.

3.3.3.1 Mis-Dump

Any scow load or hopper dredge load that is released within state waters will be classified as a mis-dump and will result in a suspension of disposal operations and prompt monitoring of affected hardbottom areas.

Redredging of such materials may be required as a prerequisite to the resumption of dredging unless the Contracting Officer, at their discretion, determines that redredging of such material is not practical or will impact more neighboring hardbottom. In addition, the Contractor shall notify the Contracting Officer within 24 hours of a misplaced dump.

Corrective actions shall be implemented by the next offload at no additional expense to the Government, and the Contracting Officer shall be informed of actions taken.

3.3.4 Spillage and Leakage

Any dredged material which is lost in transit or permitted to flow into the offshore waters or onto the upland from the point the sand is discharged on the beach will not be subject to payment. The development of a leak shall be promptly repaired and the dredge and pumpout operations shall be shut down until repairs are completed to the satisfaction of the Contracting Officer. Failure to repair leaks or change the method of operations, which result in overflow, leakage or spillage that exceeds turbidity and water quality standards during loading and transport to the discharge site, will result in suspension of dredging and pumpout operations and prompt repair or change in operation.

3.3.4.1 Barges, Hopper Dredges and Scows

Water and excavated material shall not be permitted to overflow or spill out of barges, dump scows, or hopper dredges while in route. Excessive leakage is defined by average loss of draft during transit from the dredging area to the offloading area (forward draft loss plus aft draft loss divided by 2) in excess of 1 foot. Excessive leakage may be classified as a mis-dump and be subject to requirements given in subparagraph 3.3.3.1 MIS-DUMP.

3.3.5 Misplaced Materials

If any material is deposited other than in places designated or approved, the Contractor may be required to remove such misplaced material and redeposit it where directed at their expense.

3.3.6 Barges

Water and dredged materials shall not be permitted to overflow or spill out of barges while transporting to the disposal site(s). Failure to repair leaks or change the method of operation which is resulting in overflow or spillage will result in suspension of dredging operations and require prompt repair or change of operation to prevent overflow or spillage as a prerequisite to the resumption of dredging.

3.3.7 Electronic Tracking System (ETS)

The Contractor shall furnish an ETS for surveillance of the movement and disposition of dredged material during excavation and disposal. This ETS shall be established, operated and maintained by the Contractor to continuously track in real-time the horizontal location and draft condition of the disposal vessel for the entire dredging cycle, including dredging area and disposal area. The ETS shall be capable of displaying and recording in real-time the disposal vessel's draft and location.
