The U.S. Environmental Protection Agency has removed the Portsmouth Naval Shipyard in Kittery from its National Priorities List of contaminated Superfund sites after 30 years of extensive remediation. Removal of contaminated soil, sediment and other hazardous materials at the 278-acre shipyard is complete, and no future remediation is required, the agency announced Friday. However, ongoing operation, maintenance, land use controls and monitoring activities will continue at the site as needed.
