Staten Island/New Jersey Urban Air Toxics Assessment Project

Printer-friendly version

The project was a program of ambient air monitoring and meteorological data collection from October 1987 through September 1989, and indoor air sampling from July 1990 through mid-March 1991. An emission inventory was conducted to assist source identification and support risk management where the risk assessment indicated such a need.

This study examined the levels of toxic air pollutants in the Staten Island/New Jersey area and was designed to assess the health risks (cancer and noncancer) to the residents of Staten Island due to the emission of these toxic air pollutants. Estimation of risk of cancer and noncancer effects from lifetime inhalation exposure to air toxics released from point, area, and mobile sources. A limited study of indoor air and an odor monitoring study was also carried out.

Completed reports available from National Technical Information Service (NTIS), telephone number (703) 878-4650.

1. As a result of this project, will further data be collected, monitoring be conducted, or additional problem identification studies undertaken? Will refinements be made to modeling or exposure and/or toxicity assumptions?

2. If the project is complete, what recommendations were made to reduce risk and/or emissions or otherwise mitigate the impacts of the problems identified as a result of this project?

The results of this project have been used by EPA towards fulfilling the mandates of the Urban Area Source Programs. The Agency for Toxic Substance and Disease Registry (ATSDR) has used the data from this study in its health screening focusing on the Fresh Kills Landfill in Staten Island. Some of the monitoring sites became the foundation of New York State's air toxics monitoring network.

3. If the project is complete, were reduction activity emissions or risk reductions calculated?    

3.a. Are reduction factors being developed?    

3.b. What are the expected reductions achieved by the individual activities?

3.c. Additional Comments:

4. Will the results of this project contribute to regulatory development, enforcement actions, or voluntary actions?

5. Are future projects/efforts planned or refined as a result of this project?

Region 2 provided the project results for use in EPA's air toxics risk reduction efforts responding to Clean Air Act mandates.

6. Are there any major uncertainties or cautions regarding the project process or findings?

7. Are there any lessons learned that would benefit other projects?

Strong leadership with resources, influence, credibility, power, and determination is essential to the success of such a project that spans federal and state agencies and academic institutions.

Using one sampling organization and one analytical laboratory will remove the contribution of interlaboratory differences to the reported concentrations and improve ability to observe statistically significant spatial variation in concentrations across the monitoring sites.

When a project spans years, staff assignment changes may impair participation through the end of the project and the writing reports that are based on contributions from subcommittees.

Microinventories conducted by walking every block within 1 to 2 km of a monitoring site are valuable complements to the standing databases in learning about sources in a neighborhood and local impacts on a monitor.
