Penalty for violations of the Ocean Dumping Act

Under a recent settlement with the U.S. Environmental Protection Agency (EPA), Cashman Dredging & Marine Contracting Co., LLC, based in Quincy, Mass., will pay a penalty of $185,000 for alleged violations of the Marine Protection, Research, and Sanctuaries Act (MPRSA, also known as the Ocean Dumping Act).

EPA alleged that the violations occurred during the transport of dredged material from New Bedford Harbor in Mass. to the Rhode Island Sound Disposal Site (RISDS).

On one occasion, a disposal vessel operated as part of the project dumped its load of dredged material 2.6 miles outside the authorized disposal site and on three separate occasions, dumped it in the wrong locations within the RISDS.

The company’s noncompliance was verified in part by the electronic monitoring devices onboard the disposal vessels. The company was cooperative with EPA and the U.S. Army Corps of Engineers during the enforcement investigation and case settlement negotiations and has committed to making changes in its operations to ensure compliance with MPRSA in the future.

“Proper disposal of dredged material plays a vital part in protecting our oceans,” said EPA New England Acting Regional Administrator Deborah Szaro. “EPA works to enforce federal ocean dumping requirements to protect the marine environment while maintaining safe maritime navigation.”

This action was the result of a coordinated investigation by EPA and the USACE, which issues permits for the disposal of dredged material. Under the Ocean Dumping Act, EPA designates dredged material disposal sites for long-term use.

Companies that perform the dredging of harbors and other waterways are required to meet all state and federal permit conditions for both the removal and disposal of dredged sediments.

To avoid incidents such as those described in this case, it is critical for contractors to ensure that the dredging, transportation, and disposal of sediments are carefully performed, and that they and their subcontractors pay close attention to such things as: making sure that dredging crews are well trained; adjusting loading levels to match sea conditions; properly maintaining the equipment used for transporting and monitoring the disposal of dredged material; and closely following site management and monitoring plans designed to avoid impacts to ecologically sensitive areas.

EPA and the USACE continue to work closely with the dredging industry to ensure that these practices are followed, and to seek improvements in the dredging process whenever possible.
