The EPA issues a publication which states that in the event of a terrorist attack causing the release of hazardous substances, the EPA would respond under the authority of the NCP (see 1972). “The US Environmental Protection Agency (EPA) has statutory authorities and responsibilities to prepare for and respond to emergencies involving oil and hazardous substances, pollutants or contaminants, which include chemical, biological and radiological materials that could also be components of a weapon of mass destruction (WMD)…. EPA carries out its preparedness and response efforts primarily under the mandate of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) and the Radiological Response Program.” [Environmental Protection Agency, 5/2000 pdf file]

Samples from water runoff into the Hudson and East Rivers indicate elevated levels of polychlorinated biphenyls (PCBs), dioxin, asbestos and metals. [Environmental Protection Agency, 10/3/2001]

The EPA publishes a summary of results from the air-monitoring program it implemented shortly after the 9/11 attacks. The summary covers the period between September 11 and September 30.
bullet “Out of a total of 442 air samples EPA has taken at Ground Zero and in the immediate area, only 27 had levels of asbestos above the standard EPA uses to determine if children can re-enter a school after asbestos has been removed—a stringent standard based upon assumptions of long term exposure. OSHA has analyzed 67 air samples from the same area, and all were below the OSHA workplace standard for asbestos.”
bullet “All fifty-four air samples from EPA’s four monitors in New Jersey found no [asbestos] levels above EPA’s standard. Another 162 samples were taken from EPA’s monitors at the Fresh Kills landfill in Staten Island, where debris from the World Trade Center is being taken; only two exceeded EPA’s standard.”
bullet “Of 177 bulk dust and debris samples collected by EPA and OSHA and analyzed for asbestos, 48 had levels over 1 percent, the level EPA and OSHA use to define asbestos-containing material. Although early samples from water runoff into the Hudson and East Rivers showed some elevated levels of polychlorinated biphenyls (PCBs), dioxin, asbestos and metals, recent results find non-detectable levels of asbestos, and PCBs and polycyclic aromatic hydrocarbons (PAHs) and metals below the level of concern.”
bullet EPA and OSHA samples from Ground Zero and surrounding areas did not contain levels of lead, iron oxide, zinc oxide, copper or beryllium exceeding OSHA limits.
bullet The EPA “has measured dioxin levels in and around the World Trade Center site that were at or above EPA’s level for taking action.” However, the risk from dioxin is based on long term exposure, EPA claims, adding that the agency and OSHA “expect levels to diminish as soon as the remaining fires on the site are extinguished.” The exact figures of the dioxin levels, however, are startling. More than a year later, the EPA will publish a report which includes the raw dioxin data for this period indicating that dioxins levels on some days were almost six times the highest dioxin level ever recorded in the US (see December 27, 2002).
bullet “Of the 36 samples of volatile organic compounds (VOCs) taken around Ground Zero to assist response workers in determining the appropriate level of respiratory protection, several samples have been above the OSHA standard for workers. None presented an immediate risk to workers, and the levels are expected to decline when the fires are out.” [Environmental Protection Agency, 10/3/2001]

The New York Environmental Law and Justice Project obtains internal EPA documents containing data that the agency did not include in the monitoring results it posted on its website on October 3 (see October 3, 2001). The documents, which include hundreds of pages of daily monitoring reports, reveal that “[d]ioxins, PCBs, benzene, lead and chromium are among the toxic substances detected in the air and soil around the WTC site by Environmental Protection Agency [monitoring] equipment—sometimes at levels far exceeding federal levels.” For example, one test indicated water being discharged into the Hudson River contained chromium, copper, lead and zinc at levels “elevated to several orders of magnitude above ambient water-quality criteria for most metals.” Also included is disturbing data about the air quality. “On numerous days, sulfur dioxide readings in the air at a half-dozen sites in Lower Manhattan have been far higher than the EPA’s ambient air quality standards,” one document reveals.
