The New York City Department of Health (DOH) issues its second alert since the fall of the towers. The update, titled, “Terrorist Attack at the World Trade Center in New York City: Medical and Public Health Issues of Urgent Concern,” warns the Manhattan public: “Asbestos was used in the construction of the World Trade Center. Tests performed indicate that asbestos may be present in an area marked by Worth St. to the North, Centre and Nassau Sts. to the East, and Exchange and Thames Sts. to the South.” [New York City Department of Health, 9/13/2001] The DOH report goes on to say that the “health risk posed by a single exposure of short duration is very low” and that the “risk to persons who have not been present in the affected area following the disaster is also thought to be extremely low.” [New York City Department of Health, 9/13/2001]

EPA and OSHA announce that the majority of air and dust samples monitored in New York’s financial district “do not indicate levels of concern for asbestos” and that ambient air quality “meets OSHA standards.” The two agencies also say that OSHA has new data indicating that indoor air quality in downtown buildings “will meet standards.” The agencies’ conclusions are based on samples taken on September 13. “OSHA staff walked through New York’s Financial District… wearing personal air monitors and collected data on potential asbestos exposure levels. All but two samples contained no asbestos.… Air samples taken… inside buildings in New York’s financial district were negative for asbestos. Debris samples collected outside buildings on cars and other surfaces contained small percentages of asbestos, ranging from 2.1 to 3.3—slightly above the 1 percent trigger for defining asbestos material.” [Occupational Safety and Health Administration, 9/14/2001] But the EPA improperly implies that the one percent level is a safety benchmark (see (September 12, 2001)), even though it had previously acknowledged that airborne asbestos particles are unsafe at any level (see September 14, 2001). Furthermore, its test results are not accurate, as they are based on the outdated polarized light microscopy (PLM) testing method, which is incapable of identifying fine fibers and which cannot reliably detect asbestos when it is present in concentrations below one percent (see November 20, 1990).

EPA administrator Christine Todd Whitman says with regard to Manhattan’s air quality, “[T]here is no reason for concern.” She says that her agency is regularly sampling airborne particles and that findings indicate that most locations have an asbestos level of less than one percent—the amount above which the EPA considers a material to be “asbestos-containing”—but notes that the highest recorded reading so far was 4.5 percent (see (Between 10:00 a.m. and 11:00 a.m. September 11, 2001)). [Newsday, 9/16/2001] But the EPA is wrong to use the one percent level as if it were a safety benchmark (see (September 12, 2001)). Furthermore, its test results are not accurate, as they are based on the outdated polarized light microscopy (PLM) testing method which is incapable of identifying fine fibers and which cannot reliably detect asbestos when it is present in concentrations below one percent (see November 20, 1990).

The Department of Health and Human Services (HHS) publishes a “fact sheet” on the dust and debris that blanketed surrounding streets and penetrated numerous buildings during the collapse of the World Trade Center. The first section, titled, “What is in the dust,” states only: “Dust is a mixture of very fine particles that originally made-up the materials of the WTC and the aircraft that struck it. These particles differ depending on what material the dust came from, how the dust was created, and what happened to the dust after it was released. Analysis of dust samples will provide information on components of the dust. We expect that materials that would be present would be at concentrations lower than those normally associated with health effects.” The flyer makes no effort to name the toxic chemicals and other harmful substances that were known to have been in the two towers.

[Source: ABC News/ Associated Press]The Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA) release a joint statement asserting that the air in downtown New York City is safe to breathe. “New samples confirm previous reports that ambient air quality meets OSHA standards and consequently is not a cause for public concern,” the agencies claim. [Environmental Protection Agency, 9/16/2001] However, the government’s statements are based on ambient air quality tests using outdated technologies. [St. Louis Post-Dispatch, 1/14/2002] Furthermore, it will later be learned that the press release was heavily edited under pressure from the White House’s Council on Environmental Quality (CEQ). Critical passages in the original draft were either deleted or modified to downplay public health risks posed by contaminants that were released into the air during the collapse of the World Trade Center.

EPA Administrator Christie Whitman announces that results from further air and drinking water monitoring near the WTC site and the Pentagon indicate that there are few significant risks to public health. “We are very encouraged that the results from our monitoring of air quality and drinking water conditions in both New York and near the Pentagon show that the public in these areas is not being exposed to excessive levels of asbestos or other harmful substances,” she says. “Most” of the 62 dust samples taken by the agency contained less than one percent of asbestos. [Environmental Protection Agency, 9/18/2001] The EPA incorrectly uses the one percent level of ambient asbestos as if it were a safety benchmark (see (September 12, 2001)). Moreover, the test results Whitman cites are based on the less sensitive and outdated polarized light microscopy (PLM) testing method which is incapable of identifying ultra-fine asbestos fibers and which cannot reliably detect asbestos when present in concentrations below one percent (see November 20, 1990). Whitman’s statement also observes that where asbestos levels have exceeded the EPA’s one percent “level of concern,” the “EPA has operated its 10 High Efficiency Particulate Arresting (HEPA) vacuum trucks to clean the area and then resample.” She adds that the trucks have also cleaned the “streets and sidewalks in the Financial District in preparation for… return to business.” [Environmental Protection Agency, 9/18/2001] However, it is later discovered that the contractor hired to clean the streets failed to equip the vacuum trucks with the required HEPA filters.

EPA Administrator Christie Whitman assures New Yorkers that environmental conditions in Manhattan—both inside and outside—are safe, and provides a summary of the tests that have so far been performed on the city’s air and drinking water.
Water - Whitman says: “As we continue to monitor drinking water in and around New York City, and as EPA gets more comprehensive analysis of this monitoring data, I am relieved to be able to reassure New York and New Jersey residents that a host of potential contaminants are either not detectable or are below the Agency’s concern levels. Results we have just received on drinking water quality show that not only is asbestos not detectable, but also we can not detect any bacterial contamination, PCBs or pesticides.” She does say however that “following one rainstorm with particularly high runoff, we did have one isolated detection of slightly elevated levels of PCBs (see September 14, 2001).”
Outdoor air - Whitman says that outdoor air sampling does not indicate the existence of significant public health risks. This claim is based on results obtained using the outdated polarized light microscopy (PLM) testing method (see September 12, 2001) which is incapable of identifying ultra-fine fibers and which cannot reliably detect asbestos when present in concentrations below one percent (see November 20, 1990). Even though Whitman denies a significant risk to public health, she does say “seven samples taken at or near Ground Zero have had marginally higher levels of asbestos that exceed EPA’s level of concern,” and that her agency has “done a total of 101 dust samples, of which 37 were slightly over the one percent asbestos.” Whitman does not mention that the EPA’s “level of concern” is not a safety benchmark (see (September 12, 2001)) but rather the detection limit of the polarized light microscopy (PLM) testing method (see November 20, 1990).
Indoor air - Whitman claims, “New Yorkers and New Jerseyans need not be concerned about environmental issues as they return to their homes and workplaces.” But the EPA has no data indicating that indoor air is actually safe. The only indoor tests that have been conducted by the EPA were in the EPA’s Region 2 offices located in the Federal Building and a few neighboring buildings—and the results from several of these tests were positive for chrysotile asbestos (see September 13, 2001-September 19, 2001).

The New York City Department of Health issues a press release reiterating earlier public statements regarding the air quality in Manhattan and announces that the agency has distributed over 50,000 copies of the New York City Department of Health’s recommendations for tenant re-occupancy (see September 17, 2001). The press release quotes New York City Health Commissioner Neal L. Cohen, MD, who asserts that “there are no significant adverse health risks to the general public….” and “all residents and business owners should check with their building managers or owners to make sure that their buildings are safe, and have been certified for re-occupancy.” Residents and business owners who are permitted to return to their buildings “should follow Health Department recommendations to minimize exposure to dust and other particulate matter that may cause throat and eye irritation,” he says. The statement goes on to say that only people who live or work “within the general vicinity of the blast zone… and who have been approved to resume tenancy are advised to wear a dust mask while outside. Dust masks are not necessary for residents in other areas.” Tenants following the DEP’s cleanup guidelines should find it “unnecessary to wear a mask while inside buildings,” the statement says.

Several government experts testify at a New York City Council meeting on environmental conditions following the collapse of the World Trade Center towers. [New York Daily News, 11/1/2001] Kathleen Callahan, deputy regional director of the Environmental Protection Agency (EPA), insists that New Yorkers living and working near the World Trade Center site are not in danger. “The vast majority of our tests find levels of these contaminants pose no significant long term health risks to residents, business employees and visitors beyond Ground Zero,” she says, repeating what earlier EPA statements have asserted. Downplaying the danger of those areas where higher asbestos levels have been found, she states—falsely (see April 18, 1989) (see October 3, 2001-March 1, 2004) —that “EPA and Occupational Safety and Health Administration standards are set many times below the level at which you would expect health impacts.” She advises New Yorkers who live or work in the affected areas to “follow the recommendations of the New York City Departments of Health and Environmental Protection on how to clean up properly (see September 17, 2001).” [Environmental Protection Agency, 11/1/2001] Another expert, Dr. Jessica Leighton, assistant city health commissioner for environmental risk assessment, similarly states that people living and working in Lower Manhattan have little to worry about. She says in response to a question whether or not “people are safe at the present level” of contamination: “As far as the science has shown us right now, that is absolutely correct.” Like Callahan, she claims that EPA standards are overly protective. “The standards or tolerance levels that are being used are very conservative,” she claims. “For example, for asbestos, we are using the standard that is used for indoor air quality for reentry into a school after asbestos removal, which is the most stringent standard, as the tolerance level or standard for outdoor air quality in the residential areas. This is also true for other substances, such as dioxins, identified at the perimeter of the site…. Moreover, these standards have been designed to include many safety factors so that acceptable levels of exposure are far below the levels at which health effects are expected to occur.” [New York City Department of Health, 11/1/2001] Joel Kupferman, executive director of the New York Environmental Law and Justice Project, questions the accuracy of Leighton’s and Callahan’s statements and accuses them of withholding some test results. [New York Daily News, 11/1/2001] Kathryn Freed, a New York City Council Member who represents Lower Manhattan, said she was not convinced by agency assurances, noting that firemen are already showing symptoms of emphysema, a terminal disease for which there is no cure. “Just because it doesn’t reach a certain level is really irrelevant when people are sick,” says Marc Ameruso, a member of the area’s community board.

And despite recent press accounts which suggest otherwise, these findings have not changed. In fact, environmental conditions off the site have improved in recent weeks.” Callahan also says that people concerned about contamination in their homes “should follow the recommendations of the New York City Departments of Health and Environmental Protection on how to clean up properly” (see September 17, 2001).

The EPA Office of Inspector General (OIG) releases its investigative report on the EPA’s response to the environmental consequences resulting from the collapse and burning of the World Trade Center towers. [BNA Daily Environment Report, 3/20/2003; Environmental Protection Agency, 8/21/2003 pdf file] The report, titled, “EPA’s Response to the World Trade Center Disaster Collapse: Challenges, Successes, and Areas for Improvement,” concludes:
bullet The agency did not have sufficient data to support its claim that air in Lower Manhattan following September 11 was “safe to breathe” (see January 5, 2006).
bullet The White House Council on Environmental Quality (CEQ) “heavily influenced” the EPA’s press releases, minimizing the risk to public health. Selected emails analyzed by OIG “indicated that CEQ dictated the content of early press releases” (see (September 12, 2001-December 31, 2001)).
bullet The EPA does not have an adequate system for reviewing and approving the content of EPA press releases.
bullet The EPA misled the public by failing to acknowledge that “health standards do not exist” for the cumulative simultaneous impact of exposure to more than one toxin and that the synergistic effects resulting from these combinations are not well-understood.
bullet The EPA Region 2 incorrectly applied AHERA and NESHAP asbestos standards as safety benchmarks when in fact these referred to the detection limits of certain testing methods (see (September 12, 2001)).
bullet The EPA failed to consider the short-term impacts of acute exposure to various toxins.
bullet The EPA lacked sufficient data on 10 of the 14 “pollutants of concern” identified by scientists as possible components of the WTC dust and debris.
bullet The EPA based its assessments on a risk standard of 1-in-10,000 for only some of carcinogenic pollutants thought to be contained in the clouds instead of the 1-in-1,000,000 acceptable-risk standard. It also ignored the agency’s traditional reliance on the 1-in-100,000 level, which usually triggers corrective action.
bullet The OIG determined there is “no evidence that EPA attempted to conceal data results from the public.” However, EPA scientist Cate Jenkins provides evidence the EPA and the City of New York DEP did in fact alter and in effect, conceal data results (see July 15, 2004).
bullet The OIG finds that the EPA should have implemented the National Contingency Program (see 1972), which would have given EPA jurisdiction over other government agencies and control over the issue of indoor air contamination. Critics of this report will argue that the EPA had in fact implemented the NCP immediately after the attacks (see After November 1, 2001).
