BOSTON — Two companies have agreed to pay a penalty of $89,300 to settle Environmental Protection Agency claims that they violated federal lead-paint disclosure laws at the Portsmouth Naval Shipyard in Kittery, Maine, and the Naval Submarine Base New London in Groton, Conn.

Northeast Housing LLC and Balfour Beatty Military Housing Management, LLC, were accused of failing to notify 13 prospective lessees between 2007 and 2010 about potential lead-paint hazards in housing they managed.

Northeast owns the housing at both bases. Northeast is a joint venture between the Navy and a wholly owned subsidiary of Balfour Beatty Communities.

Lead-based paint was banned from housing in 1978. Exposure to lead-based paint can cause problems including intelligence quotient deficiencies, learning disabilities and impaired hearing in infants and young children.

Adults with high levels of exposure can suffer problems including issues with pregnancy, blood pressure, memory, muscles and joint.

Nine of the lessees were families with children and seven of those had children under the age of 6.

The Portsmouth Naval Shipyard has about 25 pre-1978 housing units and the Naval Submarine Base has about 735.

The companies cooperated with  EPA in correcting the violations and reaching a settlement, according to the federal agency.
