Coast Guard members are working with Miller Environmental Services and Texas General Land Office specialists to clean up naturally occurring tar balls discovered on 20-mile stretch of land from Padre Island National Seashore to the beaches of Port Aransas, Tuesday. Beachgoers contacted Coast Guard Station Port Aransas Sunday to report that tar patties were washing ashore. Sector Corpus Christi deployed personnel from their Incident Management Division to respond. Currently, a team comprised of individuals from the three agencies is surveying the shoreline and removing the tar balls.
