The EPA also is announcing a public comment period for the draft document. EPA intends to consider comments and recommendations from the public and the expert panel meeting when EPA finalizes the draft document.

The public comment period and the external peer-review workshop are separate processes that provide opportunities for all interested parties to comment on the document.

SUPPLEMENTARY INFORMATION:

1. Summary of Information About the Integrated Risk Information System (IRIS)

   IRIS is a database that contains potential adverse human health effects information that may result from chronic (or lifetime) exposure to specific chemical substances found in the environment. The database (available on the Internet at http://www.epa.gov/iris) contains

   qualitative and quantitative health effects information for more than 500 chemical substances that may be used to support the first two steps (hazard identification and dose-response evaluation) of a risk assessment process. When supported by available data, the database provides oral reference doses (RfDs) and inhalation reference concentrations (RfCs) for chronic health effects, and oral slope factors and inhalation unit risks for carcinogenic effects. Combined with specific exposure information, government and private entities can use IRIS data to help characterize public health risks of chemical substances in a site-specific situation and thereby support risk management decisions designed to protect public health.

2. Workshop Information

   Members of the public may attend the workshop as observers, and there will be a limited time for oral comments from the public. Please let ORISE know if you wish to make comments during the workshop prior to the meeting by registering on the Web site at http://www.orau.gov/trichloroethane and indicating your intent to make oral comments. Space

   is limited, and reservations will be accepted on a first-come, first- served basis.
