The Environmental Protection Agency has reached a $1 million settlement with a homebuilder that EPA officials say repeatedly violated clean-water laws, with runoff from its construction sites dumping millions of pounds of pollution into the Chesapeake Bay.

Under the proposed settlement, the New Jersey-based home giant Hovnanian will pay cash to the United States, the District of Columbia, Maryland, Virginia and West Virginia, and will agree to follow Clean Water Act regulations designed to prevent pollution from storm water runoff.
