World Trade Center: EPA's Most Recent Test and Clean Program Raises Concerns that Need to Be Addressed to Better Prepare for Indoor Contamination Following Disasters

摘要

The September 11, 2001, terrorist attacks and World Trade Center (WTC) collapse blanketed Lower Manhattan in dust from building debris. In response, the Environmental Protection Agency (EPA) conducted an indoor clean and test program from 2002 to 2003. In 2003, EPA's Inspector General (IG) recommended improvements to the program and identified lessons learned for EPA's preparedness for future disasters. In 2004, EPA formed an expert panel to, among other goals, guide EPA in developing a second voluntary program; EPA announced this program in 2006. As requested, GAO's report primarily addresses EPA's second program, including the (1) extent to which EPA incorporated IG and expert panel member recommendations and input; (2) factors, if any, limiting the expert panel's ability to meet its goals; (3) completeness of information EPA provided to the public; (4) way EPA estimated resources for the program; and (5) extent to which EPA has acted upon lessons learned regarding indoor contamination from disasters. EPA has incorporated some recommendations and input from the IG and expert panel members into its second program, but its decision not to include other items may limit the overall effectiveness of this program.
