Groton — The U.S. Environmental Protection Agency will require Electric Boat to install new equipment to prevent stormwater pollution and improve shipyard employees' training after it found that EB failed to minimize stormwater discharge into the Thames River and that an employee dumped used fiberglass resin into a storm drain.

EPA inspectors found multiple violations of the Clean Water Act at the shipyard during an inspection in April 2017, according to a news release Tuesday.

As part of a settlement with the EPA, EB will be required to install heavy metal filters on some of its storm drains and put covers on its dumpsters and other trash containers.

The company also will have to improve its stormwater management training for shipyard employees and pay a $60,000 fine as part of the settlement.

"This settlement significantly reduces stormwater pollution from Electric Boat’s facility in Groton, which means a cleaner Thames River,” EPA New England Regional Administrator Alexandra Dunn said in the news release.
