Conditional Exemptions from TSCA Section 4 Test Rules

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: EPA is granting conditional exemptions from Toxic Substances 
Control Act (TSCA) section 4 test rule requirements to certain 
manufacturers of chemical substances subject to these rules.

DATES: These conditional exemptions are effective on April 2, 1998.
FOR FURTHER INFORMATION CONTACT: Susan B. Hazen, Director, 
Environmental Assistance Division (7408), Office of Pollution 
Prevention and Toxics, Environmental Protection Agency, Rm. E-543B, 401 
M St., SW., Washington, DC 20460, (202) 554-1404, TDD (202) 554-0551, 
e-mail: TSCA-H[email protected].

SUPPLEMENTARY INFORMATION: This document grants conditional exemptions 
from TSCA section 4 test rule requirements to all manufacturers of the 
chemical substances identified below that submitted exemption 
applications in accordance with 40 CFR 790.80. In each case, EPA has 
received a letter of intent to conduct the testing from which exemption 
is sought. Accordingly, the Agency has conditionally approved these 
exemption applications because the conditions set out in 40 CFR 790.87 
have been met. All conditional exemptions thus granted are contingent 
upon successful completion of testing and submission of data by the 
test sponsors according to the requirements of the applicable test 
rule.
    If the test requirements are not met and EPA terminates a 
conditional exemption under 40 CFR 790.93, the Agency will notify each 
holder of an affected conditional exemption by certified mail or by a 
Federal Register document. This conditional approval applies to all 
manufacturers that submitted exemption applications for testing of the 
chemical substances named in the final test rules listed below from 
January 1, 1997, through December 31, 1997. Any application received 
after December 31, 1997, will be addressed separately.
    Testing reimbursement periods have terminated (sunset) for certain 
chemicals and for these chemicals, exemption notices are no longer 
required. In accordance with 40 CFR 790.45, before the end of the 
reimbursement period, persons subject to a test rule and required to 
comply with the requirements of the test rule, must submit either a 
letter of intent to test or an exemption application. ``Reimbursement 
period,'' as defined in 40 CFR 791.3, refers to a period that begins 
when the data from the last non-duplicative test to be completed under 
a test rule is submitted to EPA, and ends after an amount of time equal 
to that which had been required to develop that data or after 5 years, 
whichever is later.
    Exemption applications that were received by EPA for diethylene 
glycol butyl ether (CAS No. 112-34-5), diethylenetriamine (CAS No. 111-
40-0), and 2-mercaptobenzothiazole (CAS No. 149-30-4) were not required 
at the time they were submitted because the chemicals have a completed 
testing program, the reimbursement periods have sunset, and the 
chemicals are no longer subject to TSCA section 4 reporting 
requirements. Exemption applications received by EPA after the 
chemical's sunset date do not appear in this document. Conditional 
exemptions granted in 1997 are listed below:
