Thousands of facilities use hazardous chemicals, and hundreds of them are subject to both Department of Homeland Security anti-terrorism standards and other federal chemical safety or security programs.
The Government Accountability Office reviewed 8 such programs and compared them to DHS’s standards. GAO found some overlap, duplication, and fragmentation. For example, facilities may be developing duplicative information to comply with multiple programs. Even though some facilities may be subject to multiple programs, those not subject to DHS standards—such as water systems—may have gaps in oversight.
Eight federal programs addressing chemical safety or security from four departments or agencies that GAO reviewed contain requirements or guidance that generally align with at least half of the Department of Homeland Security’s (DHS) 18 Chemical Facility Anti-Terrorism Standards (CFATS) program standards. At least 550 of 3,300 (16 percent) facilities subject to the CFATS program are also subject to other federal programs. Analyses of CFATS and these eight programs indicate that some overlap, duplication, and fragmentation exists, depending on the program or programs to which a facility is subject. For example,
- six federal programs’ requirements or guidance indicate some duplication with CFATS. CFATS program officials acknowledge similarities among these programs’ requirements or guidance, some of which are duplicative, and said that the CFATS program allows facilities to meet CFATS program standards by providing information they prepared for other programs.
- more than 1,600 public water systems or wastewater treatment facilities are excluded under the CFATS statute, leading to fragmentation. While such facilities are subject to other programs, those programs collectively do not contain requirements or guidance that align with four CFATS standards. According to DHS, public water systems and wastewater treatment facilities are frequently subject to safety regulations that may have some security value, but in most cases, these facilities are not required to implement security measures commensurate to their level of security risk, which may lead to potential security gaps.
The departments and agencies responsible for all nine of these chemical safety and security programs—four of which are managed by DHS, three by the Environmental Protection Agency (EPA), and one each managed by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and the Department of Transportation (DOT)—have previously worked together to enhance information collection and sharing in response to Executive Order 13650, issued in 2013. This Executive Order directed these programs to take actions related to improving federal agency coordination and information sharing.
However, these programs have not identified which facilities are subject to multiple programs, such that facilities may be unnecessarily developing duplicative information to comply with multiple programs. Although CFATS allows facilities to use information they prepared for other programs, CFATS program guidance does not specify what information facilities can reuse. Finally, DHS and EPA leaders acknowledged that there are differences between CFATS requirements and the security requirements for public water systems and wastewater treatment facilities, but they have not assessed the extent to which potential security gaps may exist. By leveraging collaboration established through the existing Executive Order working group, the CFATS program and chemical safety and security partners would be better positioned to minimize unnecessary duplication between CFATS and other programs and better ensure the security of facilities currently subject to fragmented requirements.
GAO is making seven recommendations, including that DHS, EPA, ATF, and DOT identify facilities subject to multiple programs; DHS clarify guidance; and DHS and EPA assess security gaps. Agencies generally agreed with six; EPA did not agree with the recommendation on gaps. GAO continues to believe it is valid, as discussed in the report.
