Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice.

SUMMARY:

This notice announces EPA's receipt of test data regarding In Vitro Dermal Absorption Rate Testing of certain chemicals of interest to the Occupational Safety and Health Administration (OSHA). EPA received data on the following chemicals: Acetonitrile (CAS No. 75-05-8); methyl acetate (CAS No. 79-20-9); propylene dichloride (CAS No. 78-87-5); p-nitroaniline (CAS No. 100-01-6); pentane (CAS No. 109-66-0); n-heptane (CAS No. 142-82-5); and tetrahydrofuran (CAS No. 109-99-9). These data were submitted pursuant to a test rule issued by EPA under section 4 of the Toxic Substances Control Act (TSCA).

II. Test Data Submissions

Section 4(d) of TSCA requires EPA to publish a notice in the Federal Register reporting the receipt of test data submitted pursuant to test rules promulgated under section 4(a) within 15 days after these data are received by EPA.

1. Test data for acetonitrile were submitted by DuPont Chemical Solutions Enterprise and received by EPA on November 7, 2005. The submission includes a final study report titled: “Acetonitrile: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-2003-0006-0309).

2. Test data for methyl acetate were submitted by the American Chemistry Council and received by EPA on November 21, 2005. The submission includes a final study report titled: “Methyl Acetate: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-2003-0006-0315).

3. Test data for propylene dichloride were submitted by The Dow Chemical Company and received by EPA on December 14, 2005. The submission includes a final study report titled: “Propylene Dichloride: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-2003-0006-0319).

4. Test data for p-nitroaniline were submitted by Aceto Corporation and received by EPA on December 27, 2005. The submission includes a final study report titled: “Human Percutaneous Absorption and Cutaneous Disposition of [14 C]-Nitroaniline In Vitro.” (See Document ID No. EPA-HQ-2003-0006-0320).

5. Test data for pentane were submitted by the Alkanes Dermal Absorption Consortium of the American Chemistry Council and received by EPA on December 29, 2005. The submission includes a final study report titled: “Pentane: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-2003-0006-0322. This document also contains the results of In Vitro Dermal Absorption Rate Testing for n-heptane).

6. Test data for n-heptane were submitted by the Alkanes Dermal Absorption Consortium of the American Chemistry Council and received by EPA on December 29, 2005. The submission includes a final study report titled: “n-Heptane: In Vitro Dermal Absorption Rate Testing.” (See Document ID No. EPA-HQ-2003-0006-0322. This document also contains the results of In Vitro Dermal Absorption Rate Testing of pentane).

7. Test data for tetrahydrofuran were submitted by the Tetrahydrofuran Task Force (TTF) and received by EPA on November 23, 2005. The submission includes a final study report titled “Determination of the Percutaneous Absorption of THF, In Vitro, Using the Human Cadaver Skin Model.” (See Document ID No. EPA-HQ-2003-0006-0323).

These chemical substances are used in a wide variety of applications as industrial solvents, which may result in exposures of a substantial number of workers as described in the support document for the proposed rule (64 FR 31074, June 9, 1999, Table 3-Exposure Information for Chemical Substances).

EPA has initiated its review and evaluation process for these submissions. At this time, the Agency is unable to provide any determination as to the completeness of the submissions.
