EPA is making test results and the results of the Agency's review of test data available to the public through summaries that are added to TSCATS (TSCA Test Submissions), a publicly accessible computerized data base. In addition, information about testing decisions resulting from Risk Management (RM) meetings are contained in the administrative record, a central collection point established by OPPT for materials on each chemical handled by OPPT's Existing Chemical Program. Contents of the administrative record include the following items:

The public can access OPPT's public docket and administrative record in person, by going to Room B102, EPA West, 1301 Constitution Avenue, NW, Washington, DC from 8:30 am to 4:30 pm, Monday-Friday except legal holidays (photocopy facilities are available), or by writing to the TSCA Public Docket (7407M), Attention: TSCA Existing Chemicals Program RM, Office of Pollution Prevention and Toxics, U.S. Environmental Protection Agency, Ariel Rios Building, 1200 Pennsylvania Avenue, NW, Washington, DC 20460.
