TSCA Chemical Testing; Receipt of Test Data

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces EPA's receipt of test data on 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: Dipropylene glycol methyl ether (DPGME) 
(CAS No. 34590-94-8); naphthalene (CAS No. 91-20-3); diphenylamine 
(DPA) (CAS No. 122-39-4); 1-nitropropane (CAS No. 108-03-2); 2-
nitropropane (CAS No. 79-46-9); isophorone (CAS No. 78-59-1); p-
nitrochlorobenzene (CAS No. 100-00-5); and benzyl chloride (CAS No. 
100-44-7). 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 DPGME were submitted by the DPGME Dermal 
Absorption Task Group of the American Chemistry Council's Ethylene and 
Propylene Glycol Ethers Panel and received by EPA on February 22, 2006.
