II. Test Data Submissions

EPA received test data on five chemicals listed in the TSCA section 4 test rule titled “In Vitro Dermal Absorption Rate Testing of Certain Chemicals of Interest to the Occupational Safety and Health Administration,” published in the Federal Register issue of April 26, 2004 (69 FR 22402) (FRL-7312-2), and later amended by a final rule titled “Revocation of TSCA Section 4 Testing Requirements for Certain Chemical Substances,” published in the Federal Register issue of April 12, 2006 (71 FR 18650) (FRL-7751-7).

Section 4(d) of TSCA (15 U.S.C. 2603(d)) requires EPA to publish a notice in the Federal Register reporting the receipt of test data submitted pursuant to test rules promulgated under TSCA section 4(a) (15 U.S.C. 2603(a)). Each notice must:

1. Identify the chemical substance or mixture for which data have been received.

2. List the uses or intended uses of such substance or mixture and the information required by the applicable standards for the development of test data.

3. Describe the nature of the test data developed.

The following table contains the information described in this document. See the applicable CFR cite, listed in the table, for test data requirements. EPA has completed its review and evaluation process for these submissions. The reviews have been added to the docket.
