Highlights

In 2005, Hurricane Katrina's impact on the Gulf Coast included damage to the environment from chemical and hazardous materials releases. Also, the widespread demolition and renovation activities still under way in New Orleans may release asbestos fibers into the air, posing a potential additional health risk. This report, conducted at the Comptroller General's initiative, addresses (1) the Environmental Protection Agency's (EPA) actions to assess and mitigate Katrina's environmental impacts, (2) the extent to which EPA has assurance that public health is protected from asbestos inhalation risks in New Orleans, (3) the extent to which EPA's environmental health risk communications provided useful information to the public, and (4) challenges EPA faces in addressing environmental impacts.

Recommendations

Recommendations for Executive Action

Agency Affected Recommendation Status
Environmental Protection Agency To enhance EPA's ability to monitor and assess information on asbestos emissions resulting from the extensive demolition and renovation activities in New Orleans, the EPA Administrator should develop and implement an asbestos monitoring plan that addresses the potential health effects of both (1) the nonenforcement of certain asbestos requirements covering government-ordered demolitions of residences and (2) the general exemption from EPA's asbestos work practice standards for demolition and renovation activities of residential buildings with four or fewer dwelling units when done at the initiative of individual homeowners.
Closed – Implemented
In the aftermath of Hurricane Katrina, EPA took steps to monitor asbestos emissions in New Orleans but did not place monitors in areas undergoing substantial demolition and renovation, thereby limiting its assurance that public health is protected from risks associated with inhalation of asbestos fibers. While EPA increased the number of ambient (outdoor) air monitors in the area from 5 to 12, monitors effectively detect releases of asbestos from demolition activities only if they are located immediately adjacent to the demolition sites. In addition, to facilitate and expedite demolition and rebuilding following Hurricane Katrina, EPA issued "no action assurance" letters stating that it...
Environmental Protection Agency To provide environmental health risk information to the public that is timely, complete, clear, and consistent about (1) the environmental contamination to which individuals may be exposed subsequent to disasters and (2) how individuals can best protect themselves, the EPA Administrator should develop protocols to ensure that the agency's communications following disasters are timely and sufficiently disclose all of the information that affected residents would need to understand the potential health risks they may face upon returning, including information on the scope and methodology for EPA's assessments of environmental health risks.
Closed – Implemented
In July 2007, EPA released its initial National Approach to Response Crisis Communications Plan, which established EPA's process for releasing key environmental data and coordinating public information among the various levels of a response to a disaster incident. The plan identified the roles and responsibilities of EPA communications personnel and notes that the agency will ensure that messages are conveyed to the public quickly, accurately, and consistently. The plan also outlined steps the agency will follow to disseminate information to the public, including environmental data, such as soil, sediment, air, and water sampling and monitoring data. Among other things, EPA has developed...
Environmental Protection Agency To provide environmental health risk information to the public that is timely, complete, clear, and consistent about (1) the environmental contamination to which individuals may be exposed subsequent to disasters and (2) how individuals can best protect themselves, the EPA Administrator should develop clear and consistent generic information for the public regarding mitigating exposure to contaminants--such as asbestos, lead, and mold--likely to be present in many disaster situations and ensure that this information can be expeditiously communicated via all appropriate media, thereby providing the public with basic protective information at the same time that EPA is developing any additional event-specific health risk information that is needed.
Closed – Implemented
EPA formalized its National Approach to Response Crisis Communications Plan as an EPA Order in January 2009. The plan establishes EPA's process for communicating environmental information to the public during a response to a nationally significant incident (such as a natural disaster) and for coordinating public information among various EPA field, region, and headquarters offices. Among other things, the plan states that environmental data must be disseminated to the public in an understandable, timely, accurate, and consistent manner and provides direction to the EPA Incident Command Public Information Officer regarding the release of information on public health and protection....
Environmental Protection Agency To better enable EPA and its partner agencies to minimize the environmental risks resulting from future disasters, the EPA Administrator should work with potentially affected federal land management agencies, the Coast Guard, DHS, and FEMA to determine what actions are needed to ensure that environmental contamination on federal lands, such as national wildlife refuges, can be expeditiously and efficiently addressed in future disasters. Potential actions include the development of protocols or memorandums of understanding or amendments to the Stafford Act if the agencies determine that amendments are needed to achieve the timely availability of such funding when responding to disasters involving federal lands.
Closed – Not Implemented
EPA reported that the National Response Team considered this issue but decided that it was addressed by the Major Disasters, Section 405 of the Stafford Act and that no further action was needed. While Section 405 addresses a funding remedy for repairing and reconstructing federal facilities damaged or destroyed by major disasters when there is a lack or insufficiency of funds appropriated for such purpose, it does not focus on actions needed to attend to environmental contamination in future disasters. Specifically, this section of the Stafford Act does not address our recommendation which directs EPA to work with potentially affected land management agencies to proactively consider and...
Environmental Protection Agency To better enable EPA and its partner agencies to minimize the environmental risks resulting from future disasters, the EPA Administrator should provide more detailed guidance to state and local entities on managing debris disposal following disasters to better ensure protection of public health and the environment and prevent the creation of future Superfund sites. This guidance should address the selection of landfill sites for disaster debris, including advance selection of potential landfill sites, and practices to consider when making special accommodations for debris disposal in emergency situations.
Closed – Implemented
EPA's 1995 guide on planning for disposal of disaster debris acknowledges that disaster debris can overwhelm existing landfills (solid waste facilities) or force communities to use disposal options that otherwise would not be acceptable. However, the guide does not provide specific guidance on the selection of emergency landfill sites or practices that state agencies should consider when making special debris disposal accommodations following disasters. Because EPA's debris management role is limited under federal law and the National Response Plan, its guidance to states and localities on planning for disposal of disaster debris could be especially important in helping ensure that...
Environmental Protection Agency To better enable EPA and its partner agencies to minimize the environmental risks resulting from future disasters, the EPA Administrator should work with the Army Corps of Engineers to clarify each agency's role in debris disposal and develop a memorandum of understanding or other agency protocol to allow the agencies to quickly manage and recycle white goods and electronic waste following future disasters.
Closed – Implemented
As recommended, EPA worked with the Army Corps of Engineers and clarified their respective roles and responsibilities related to the management of white goods and electronics. Their agreement is documented in the 2008 National Response Framework. Specifically, when states request federal disaster assistance under Emergency Services Function #3, the Corps leads the management of electronic wastes and Freon from white goods. If disaster assistance is requested only under Emergency Services Function #10, EPA leads the management of these wastes.
