Common use of Dredging Management Plan Clause in Contracts

Dredging Management Plan. The contractor shall ensure that a Dredging Management Plan (DMP) containing Standard Operating Procedures (SOPs) for the Project is developed prior to the initiation of dredging and implemented for the duration of the dredging activity. The DMP will include the following measures to prevent release of hazardous materials during construction activities: • Personnel involved with dredging and handling the dredged material will be given training on their specific task areas, including: o Potential hazards resulting from accidental oil and/or fuel spills; o Proper dredging equipment operation; and -Proper silt curtain deployment techniques. o Proper response in the event that ordnance or munitions are encountered. • All equipment will be inspected by the dredge contractor and equipment operators before starting the shift. These inspections are intended to identify typical wear or faulty parts. • Required instrumentation to avoid spillage of dredging material will be identified for each piece of equipment used during dredging operations. • Personnel will be required to visually monitor for oil or fuel spills during construction activities. In the event that a sheen or spill is observed, the equipment will be immediately shut down and the source of the spill identified and contained. Additionally, the spill will be reported to the applicable agencies presented in the DMP. • All personnel associated with dredging activities will be trained as to where oil/fuel spill kits are located, how to deploy the oil absorbent pads, and proper disposal guidelines. The dredging barge shall have a full complement of oil/fuel spill kits on board to allow for quick and timely implementation of spill containment. • The use of oil booms will be deployed surrounding the dredging activities. In the event that a spill occurs, the oil and/or fuel will be contained within the oil boom boundary. The oil boom shall be deployed along the entire length of the outer silt curtain. • Shallow areas along the haul route will be mapped and provided to the dredge operator for review. These areas will be avoided to the extent possible to prevent propeller wash resuspension of sediment. • Load-controlled barge movement, line attachment, and horsepower requirements of tugs and support boats at the Project site will be specified to avoid resuspension of sediment. • Barge load limits and loading procedures will be identified, and the appropriate draft level will be marked on the materials barge hull. A protocol will be developed for the Project in conjunction with the U.S. Department of the Navy to address any munitions and ordnance that have been found during the Project. As required for Projects within San Diego Bay Ship Channels, the Project shall be coordinated with the Navy NAVFAC Southwest Division in San Diego for munitions clearance. Implementation of the DMP will be verified by the San Diego Water Board. The Department of the Navy will be provided an opportunity to review and comment on the DMP, particularly with respect to ordnance and munitions that have been identified in proximity to the Shipyard Site.
