ENVIRONMENTAL PROTECTION AGENCY
OPPTS-44651; FRL-6068-3]
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
Hexamethylene Diisocyanate (HDI) (CAS No. 822-06-0). These data were
submitted pursuant to an enforceable testing consent agreement/order
issued by EPA under section 4 of the Toxic Substances Control Act
(TSCA). Publication of this notice is in compliance with section 4(d)
of TSCA.
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-Hotline@epamail.epa.gov.
SUPPLEMENTARY INFORMATION: Under 40 CFR 790.60, all TSCA section 4
enforceable consent agreements/orders must contain a statement that
results of testing conducted pursuant to testing enforceable consent
agreements/orders will be announced to the public in accordance with
procedures specified in section 4(d) of TSCA.
I. What are the details of the submission?
Test data for HDI were submitted by the Chemical Manufacturers
Association (CMA) on behalf of its test sponsor companies: ARCO
Chemical Company, Newtown Square, PA; Bayer Corporation, Pittsburgh,
PA; and Rhodia Inc. (Formerly Rhone-Poulenc Inc.), Raleigh, NC. The
reports were submitted pursuant to a TSCA section 4 enforceable testing
consent agreement/order. EPA received the data on January 29, 1999. The
submission includes three final reports entitled: 1) ``Bacterial
Reverse Mutation Assay Using Vapor-Phase Exposure for 1,6-Hexamethylene
Diisocyanate,'' 2) ``In Vitro Mammalian Cell Gene Mutation Test with an
Independent Repeat Assay Using Vapor Phase Exposure to 1,6-
Hexamethylene Diisocyanate,'' and 3) ``Acute Inhalation of
Hexamethylene Diisocyanate For a Mouse Micronucleus Assay.'' HDI is
used in the manufacture of higher molecular weight biuret
polyisocyanate resins and trimer polyisocyanate resins. HDI biuret
polyisocyanate resins and trimers are mainly used as reactive
components of two part polyurethane paint systems for automobile
refinishing, industrial maintenance, marine coatings, and other high
performance coating systems. For example, the civilian and military
aircraft industry uses aliphatic diisocyanate-containing paint almost
exclusively because of its stability in ultraviolet light. Other
consumer uses of HDI are not known at this time.
EPA has initiated its review and evaluation process for this data
submission. At this time, the Agency is unable to provide any
determination as to the completeness of the submission.
II. How do I get additional information?
EPA has established a public record for this TSCA section 4(d)
receipt of test data notice (docket number OPPTS-44651). This record
includes copies of the studies reported in this notice. The record is
available for inspection from 12 noon to 4 p.m., Monday through Friday,
except legal holidays, in the TSCA Nonconfidential Information Center
(also known as the TSCA Public Docket Office), Rm. B-607 Northeast
Mall, 401 M St., SW., Washington, DC 20460. Requests for documents
should be sent in writing to: Environmental Protection Agency, TSCA
Nonconfidential Information Center (7407), 401 M St., SW., Washington,
DC 20460 or fax: (202) 260-5069 or e-mail: oppt.ncic@epamail.epa.gov.
