The city of Port Arthur has shut down a controversial temporary dumping ground used to sort moldy debris after residents for weeks complained of health risks. The "debris management site" on 19th Street was one of three opened by the city to separate construction materials, appliances and electronics to comply with FEMA regulations, the city said when they first opened. Residents and activists celebrated after the site was closed Sunday as contractors finished their first sweep of ruined furniture and appliances left curbside. More than 12,000 structures were damaged by floodwaters after the storm hit the city, including about 80 percent of local homes.
