TSCA Chemical Testing; Receipt of Test Data

AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.

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

SUMMARY: This notice announces the receipt of test data on N-
methylpyrrolidone (NMP) (CAS No. 872-50-4), and glycidyl methacrylate 
(GMA) (CAS No. 106-91-2), submitted pursuant to testing consent orders 
under 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, [phone], TDD [phone].
SUPPLEMENTARY INFORMATION: Under 40 CFR 790.60, all TSCA section 4 
consent orders must contain a statement that the results of testing 
conducted pursuant to these testing consent orders will be announced to 
the public in accordance with section 4(d).

I. Test Data Submissions

    Test data for N-methylpyrrolidone (NMP) were submitted by the NMP 
Producers Group pursuant to a testing consent order at 40 CFR 799.5000. 
They were received by EPA on November 22, 1995. The submission includes 
three final reports entitled ``N-Methylpyrrolidone - Subchronic Oral 
Toxicity Study in B6C3F1 Mice, Administration in the Diet for 3 
Months''; ``Subchronic Oral Toxicity: 90-Day Feeding and Neurotoxicity 
Study in Rats with N-Methylpyrrolidone (NMP)''; and ``Oral, Dermal, and 
Inhalation Pharmacokinetics and Disposition of [2-14C] NMP in the 
Rat''. This chemical is an inert, stable, polar solvent that is used in 
a wide variety of processes. Its commercial uses result from its strong 
and frequently selective solvent power. One of the major uses of NMP is 
the extraction of aromatics from lubricating oils. It is also used as a 
medium for polymerization and as a solvent for finished polymers. It is 
the preferred solvent in a variety of chemical reactions and the 
manufacture of numerous chemical intermediates and in products such as 
plastics, surface coatings, and pesticides. An important new use of 
this chemical is as a substitute for methylene chloride in paint 
strippers. NMP is also used in the recovery and purification of 
acetylenes, olefins, and diolefins, in the removal of sulfur compounds 
from natural and refinery gases, and in the dehydration of natural gas.
    Test data for glycidyl methacrylate were submitted by the GMA 
Industry Group pursuant to a testing consent order at 40 CFR 799.5000. 
They were received by EPA on December 4, 1995. The submission includes 
two final reports entitled ``Evaluation of Glycidyl Methacrylate (GMA) 
in the Chinese Hamster Ovary Cell/Hypoxanthine-Guanine-Phosphoribosyl 
Transferase (CHO/HGPRT) Forward Mutation Assay''; and ``Evaluation of 
Glycidyl Methacrylate (GMA) in the Mouse Bone Marrow Micronucleus 
Test''. GMA, a glycidol derivative, is an epoxy resin additive used in 
paint coating formulations and adhesive applications.
    EPA has initiated its review and evaluation process for these data 
submissions. At this time, the Agency is unable to provide any 
determination as to the completeness of the submissions.

II. Public Record

    EPA has established a public record for this TSCA section 4(d) 
receipt of data notice (docket number OPPTS-44620). This record 
includes copies of all 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 Public Docket Office, Rm. B-607 
Northeast Mall, 401 M St., SW., Washington, DC 20460.

    Authority: 15 U.S.C. 2603.
