OCEAN SPINGS, Miss. (AP) - The Gulf Islands National Seashore has closed about 30 acres of Horn Island to the public indefinitely after BP cleanup workers discovered tiles containing asbestos.
GINS superintendent Dan Brown says 1 of 12 areas tested at that site also came back positive for mustard gas.
Brown says the hazardous materials are on the northwestern shore in an area that contains the remains of a military facility that was active in the 1940s.
The cleanup of the affected area may take several years.
Brown said Monday that the material was scattered over a site about an acre in size. Park rangers said a larger site would be closed to visitors during the cleanup.
