ERA’S Response to Indoor Environment
Consistent With Statutes and Regulations
But May Have Delayed Needed Health Protection
EPA’s actions to evaluate, mitigate, and control risks to human health from
exposure to indoor air pollutants in the WTC area were consistent with applicable
statutes and regulations. EPA is not obligated to respond to a given emergency,
and New York City exercised a lead role regarding indoor air. Nonetheless, we
believe EPA could have taken a more proactive approach regarding indoor air
cleanup. EPA began to assume a lead role in February 2002, when the Agency
initiated a multi-agency task force to address concerns about the indoor
environment. Prior to initiation of the EPA-led cleanup, many WTC area
residents had returned to their homes, and a study indicated most of them had not
followed recommended cleaning practices. The full extent of public exposure to
indoor contaminants resulting from the WTC collapse is unknown.
Concerns Expressed Regarding Indoor Contamination Response
The public and elected officials began raising concerns about the extent that
indoor spaces were contaminated with asbestos and other contaminants shortly
after the WTC collapse. New York City, which initially took lead responsibility
for addressing indoor air, was criticized for:
• Delegating testing and remediation efforts to building owners and residents.
• Not enforcing proper procedures for cleaning asbestos.
• Giving improper advice to the public on testing and cleaning procedures.
EPA was criticized for not initially taking a greater role in indoor testing and
cleaning. U.S. Congressman Jerrold Nadler (D-NY), whose district includes
Lower Manhattan, contended that EPA violated the law by allowing New York
City to handle indoor air quality and not exercising oversight authority pursuant to
the National Contingency Plan (NCP). EPA maintained that the NCP does not
create a right to a Federal response and its approach to indoor air was a “proper
and legal exercise of our discretion” under the NCP.
In the immediate aftermath of the disaster, EPA undertook several activities to
address various issues related to indoor air. However, according to EPA
documentation. New York City officials stated on September 30, 2001, that the
City would not be requesting assistance from EPA regarding residential sampling
or reoccupation issues, or roof debris cleanup.
