1. Background Information

Immediately following the September 11, 2001, terrorist attack on New York City's World Trade Center, many Federal agencies, including the EPA, were called upon to focus their technical and scientific expertise on the national emergency. EPA, other Federal agencies, New York City and New York State public health and environmental authorities focused on numerous cleanup, dust collection and ambient air monitoring activities to ameliorate and better understand the human health impacts of the disaster. Detailed information concerning the environmental monitoring activities that were conducted as part of this response is available at the EPA Response to 9-11 Web site at​wtc/​.

In addition to environmental monitoring, EPA efforts also included toxicity testing of the dust on laboratory mice, as well as the development of a human exposure and health risk assessment. This risk assessment document, Exposure and Human Health Evaluation of Airborne Pollution from the World Trade Center Disaster (​ncea/​wtc.htm), has been subjected to public comment and expert peer review and is currently undergoing revisions prior to finalization. Numerous additional studies by other Federal and State agencies, universities and other organizations have documented impacts to both the outdoor and indoor environments and to human health.

While these monitoring and assessment activities were ongoing and the cleanup at Ground Zero itself was occurring, EPA began planning for a program to clean and monitor residential apartments. From June until December 2002, residents impacted by WTC dust and debris in an area of about 1 mile by 1 mile south of Canal Street were eligible to request federally funded cleaning and monitoring for airborne asbestos or only monitoring of their residences. The cleanup continued into the summer of 2003, by which time EPA had cleaned and monitored 3,400 apartments and monitored an additional 800 apartments. Detailed information on this portion of the EPA response is also available at​wtc/​.

A critical component of understanding long-term human health impacts is the establishment of health registries. The WTC Health Registry is a comprehensive and confidential health survey of those most directly exposed to the contamination resulting from the collapse of the WTC towers. It is intended to give health professionals a better picture of the health consequences of 9/11. It was established by the Agency for Toxic Substances and Disease Registry (ATSDR) and the New York City Department of Health and Mental Hygiene (NYCDHMH), in cooperation with a number of academic institutions, public agencies and community groups. Detailed information about the registry can be obtained from the registry Web site at:​html/​doh/​html/​wtc/​index.html.

In order to obtain individual advice on the effectiveness of these programs, unmet needs and data gaps, EPA has convened a technical panel of experts who have been involved with WTC assessment activities. Dr. Paul Gilman, EPA Science Advisor, serves as Chair of the panel, and Dr. Paul Lioy, Professor of Environmental and Community Medicine at the Environmental and Occupational Health Sciences Institute of the Robert Wood Johnson Medical School—UMDNJ and Rutgers University, serves as Vice Chair. A full list of the panel members and a charge statement and operating principles for the panel are available from the panel Web site listed above. Panel members will provide individual advice on issues the panel addresses. Panel meetings will occur in New York City and nearby locations. All of the meetings will be announced on the Web site and by a Federal Register notice, and they will be open to the public for attendance and also to provide brief oral comment.

The WTC Expert Panel has met seven times as of the date of this notice. Mostly, panel members have addressed the development of a design for a sampling program to determine the geographic extent of WTC impacts to the indoor environment. For the last two meetings, there have also been presentations and discussions on studies, either underway or completed, which have addressed human health impacts resulting from the collapse of the WTC towers.

Changes will be made to the Draft Proposed Sampling Program to Determine Extent of World Trade Center Impacts to the Indoor Environment based on comments received as a result of this notice. A final sampling program document will then be posted on the WTC Expert Panel's Web site.

2. How to Submit Information to E-Docket

EPA has established an official public docket for information pertaining to this action, Docket ID No. ORD-2004-0003. The official public docket is the collection of materials, excluding Confidential Business Information (CBI) or other information whose disclosure is restricted by statute, that is available for public viewing at the Office of Environmental Information (OEI) Docket in the Headquarters EPA Docket Center (EPA/DC), EPA West Building, Room B102, 1301 Constitution Ave., NW., Washington, DC. The EPA Docket Center Public Reading Room is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal holidays.
