Test Guidelines; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

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

SUMMARY: EPA has established a unified library for test guidelines 
issued by the Office of Prevention, Pesticides and Toxic Substances 
(OPPTS), and is announcing the availability of final test guidelines 
for the Series 870--Health Effects Test Guidelines. The final 
guidelines have been harmonized between the Office of Pesticide 
Programs (OPP) and the Office of Pollution Prevention and Toxics (OPPT) 
and, to the extent possible, with the Organization for Economic 
Cooperation and Development (OECD) Guidelines for the Testing of 
Chemicals. The test guidelines have been reviewed at various Scientific 
Advisory Panel (SAP) meetings, the most recent of which was held on 
October 29 and 30, 1996, as announced by notice in the Federal Register 
(61 FR 31522, June 20, 1996) (FRL-5367-7). The guidelines have been 
revised where appropriate in response to SAP and public comments. This 
notice also describes the unified library of OPPTS test guidelines.

ADDRESSES: The guidelines are available from the U.S. Government 
Printing Office (GPO), Washington, DC 20402 on disks or paper copies: 
call (202) 512-0132. The guidelines are also available electronically 
in PDF (portable document format) from EPA's World Wide Web site 
(http://www.epa.gov/epahome/research.htm) under the heading 
``Researchers and Scientists/Test Methods and Guidelines/OPPTS 
Harmonized Test Guidelines.''

SUPPLEMENTARY INFORMATION:
    Electronic Availability: Electronic copies of this document and 
various support documents are available from the EPA Home Page at the 
Federal Register--Envirnonmental Documents entry for this document 
under ``Laws and Regulations'' (<a href="http://www.epa.gov/fedrgstr/EPA-TOX/
1998/">http://www.epa.gov/fedrgstr/EPA-TOX/
1998/</a>).

I. EPA's Process for Developing a Unified Library of Test 
Guidelines

    EPA's Office of Prevention, Pesticides and Toxic Substances has 
been engaged in a multi-year project to harmonize and/or update test 
guidelines among the Office of Pesticide Programs, the Office of 
Pollution Prevention and Toxics, and the Organization for Economic 
Cooperation and Development. The goals of the project include the 
formulation of harmonized OPP and OPPT guidelines for those in common 
between the two programs, the harmonization of OPPT and/or OPP 
guidelines with those of the OECD, as well as the updating of any 
guidelines unique to OPP or OPPT programs.
    Test guidelines that are changed substantively from the existing 
test guidelines in the Pesticide Assessment Guidelines or 40 CFR 
158.795 through 158.799 in the harmonization process or through other 
updating/amending activities, or which are new (e.g., for a previously 
unaddressed test endpoint) are made available for public comment by 
notice in the Federal Register. Additionally, EPA submits substantively 
revised and new test guidelines to peer review by the FIFRA SAP and 
other expert scientific panels. Guidelines which are reformatted but 
not changed in any substantive way are not made available for public 
comment or submitted to peer review.
    All final guidelines are available through the Internet on the EPA 
World Wide Web Home Page as a unified library of OPPTS test guidelines 
for use by either EPA program office. Printed versions of the unified 
library of OPPTS test guidelines are also available to the public 
through GPO, see ``ADDRESSES'' at the beginning of this document. For 
purposes of this Federal Register notice, ``publication'' of the 
unified library of guidelines generally describes the availability of 
these final guidelines through GPO and the Internet. Because 
harmonization and updating is an ongoing task, some guidelines 
available via GPO and the Internet may be revised in the future. These 
efforts will ensure that industry is provided with test guidelines that 
are current.
    The test guidelines appearing in the unified library are given 
numerical designations that are different from the designations 
provided in the Code of Federal Regulations (CFR) at 40 CFR parts 158, 
795, 796, 797, 798, and 799. OPPTS test guidelines will be published in 
10 disciplinary series as follows:
    Series 810--Product Performance Test Guidelines
    Series 830--Product Properties Test Guidelines
    Series 835--Fate, Transport and Transformation Test Guidelines
    Series 840--Spray Drift Test Guidelines
    Series 850--Ecological Effects Test Guidelines
    Series 860--Residue Chemistry Test Guidelines
    Series 870--Health Effects Test Guidelines
    Series 875--Occupational and Residential Exposure Test Guidelines
    Series 880--Biochemicals Test Guidelines
    Series 885--Microbial Pesticide Test Guidelines
    The Agency issues Federal Register notices periodically announcing 
any new test guidelines added to the OPPTS unified library. As each set 
of guidelines is published, it will be accompanied by a ``Master List'' 
which cross references the new OPPTS guideline numbers to the original 
OPP, OPPT, and OECD numbers.

II. OPP and OPPT Procedures

    For pesticide registration, explicit test requirements are set out 
in 40 CFR part 158 which refers to specific guidelines by guideline 
number. Once final revised guidelines are available through GPO and the 
Internet, the earlier Pesticide Assessment Guidelines that were 
available through the National Technical Information Service (NTIS) 
will be removed from distribution. Studies initiated 45 days or more 
after publication of the notice of availability in the Federal Register 
should be performed in accordance with the revised guidelines; however, 
registrants should discuss effective dates for long term studies with 
the EPA Product Manager. As test guidelines are published, the Agency 
will inform industry and the general public by means of Federal 
Register notices. In addition, Data Call In letters to pesticide 
registrants will carry a dual numbering system for test guidelines 
until all test guidelines have been published. Part 158, which is 
currently being revised, will also carry a dual numbering system

[[Page 41846]]

for test guidelines when it is proposed in the Federal Register.
    In contrast, OPPT had previously published its pre-harmonization 
test guidelines in 40 CFR parts 795 through 798. Recent TSCA test 
guidelines, based on harmonized test guidelines, have been published in 
part 799. TSCA test guidelines are referenced in test standards 
promulgated in chemical-specific test rules in part 799. To the extent 
that a person is subject to a test rule which references a pre-
harmonization guideline published in 40 CFR parts 795 through 798, the 
test rule still requires compliance with the pre-harmonization test 
guideline that was referenced by the rule. However, if the person 
subject to the test rule is interested in seeking a modification to the 
requirement to comply with the test standard promulgated in the test 
rule, EPA encourages that person to consult the modification procedures 
outlined in 40 CFR part 790. EPA has removed and will continue to 
remove from the CFR those pre-harmonization guidelines that are no 
longer referenced in an applicable test rule.

III. Peer Review of Series 870 Health Effects Test Guidelines

    The Agency has updated and harmonized test guidelines for health 
effects (870 Series) and submitted the revisions to peer review by the 
FIFRA SAP on October 29 and 30, 1996. EPA also made these revised 
guidelines available to the public for comment through the OPP docket 
and on the Internet through the EPA Home Page. Guidelines in this 
series have been revised in response to peer review and public comment. 
In addition, the series includes four new guidelines: Neurophysiology, 
Sensory Evoked Potentials (OPPTS 870.6855); Domestic Animal Safety 
(OPPTS 870.7200); Dermal Penetration (OPPTS 870.7600); and 
Immunotoxicity (OPPTS 870.7800). Two guidelines have been deleted: 
Preliminary Developmental Toxicity Screen (OPPTS 870.3500) and 
Inhalation Developmental Toxicity Study (OPPTS 870.3600). One guideline 
has been removed from the harmonized category: Acute Inhalation with 
Histopathology (OPPTS 870.1350). Three guidelines have been totally 
revised and updated: Prenatal Developmental Toxicity (OPPTS 870.3700); 
Reproduction and Fertility Effects (OPPTS 870.3800); and Metabolism and 
Pharmacokinetics (OPPTS 870.7485). The sub-chronic guidelines for all 
routes of exposure have been updated to match the new OECD Guidelines 
408 and 409. Under genetic toxicology testing, two guidelines 
addressing reverse mutation have been combined into one guideline: 
Bacterial Reverse Mutation Test (OPPTS 870.5100). Six guidelines have 
been harmonized with the most recent OECD updated tests. One new 
guideline has been added: Mammalian Spermatogonial Chromosome 
Aberration Test (OPPTS 870.5380). One OPPT guideline (40 CFR 798.5955 
Heritable Translocation Test in Drosophila melanogaster) was not 
updated due to lack of use. The remaining twelve mutagenicity 
guidelines were not changed substantively, but were reformatted for 
consistency with other harmonized 870 Series guidelines. A detailed 
description of the response to comments and the changes to guidelines 
are available under docket control number OPP-00499 in the Public 
Information and Records Integrity Branch, Information Resources and 
Services Division, Office of Pesticide Programs, Rm. 119, Crystal Mall 
#2, 1921 Jefferson Davis Hwy., Arlington, VA; telephone: (703) 305-
5805, or by mail: Public Information and Records Integrity Branch, 
Information Resources and Services Division (7502C), Office of 
Pesticide Programs, Environmental Protection Agency, 401 M St., SW., 
Washington, DC 20460.

IV. Request for Comment on Potential Voluntary Consensus Standards 
to Consider for Future Regulatory Actions

    This notice of availability does not involve a proposed regulatory 
action that would require the Agency to consider voluntary consensus 
standards pursuant to section 12(d) of the National Technology Transfer 
and Advancement Act of 1995 (NTTAA), Pub. L. 104-113, section 12(d) (15 
U.S.C. 272 note). Section 12(d) directs EPA to use voluntary consensus 
standards in its regulatory activities unless to do so would be 
inconsistent with applicable law or otherwise impractical. Voluntary 
consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, business practices, 
etc.) that are developed or adopted by voluntary consensus standards 
bodies. The NTTAA requires EPA to provide Congress, through OMB, 
explanations when the Agency decides not to use available and 
applicable voluntary consensus standards when the NTTAA directs the 
Agency to do so.
     As indicated earlier, these guidelines represent an Agency effort 
to harmonize the test guidelines between OPP and OPPT, as well as 
harmonizing the OPP and OPPT test guidelines with those of the OECD. 
The process for developing and amending these test guidelines includes 
the extensive involvement of the scientific community, including peer 
review by the FIFRA SAP and other expert scientific panels, and 
providing extensive public comment.
    In the future, these test guidelines could be incorporated into 
regulatory actions taken by EPA pursuant to TSCA section 4. Although 
the NTTAA requirements do not specifically apply to the issuance of 
these particular test guidelines today, EPA invites your comment on 
whether or not there are any voluntary consensus standards that should 
be considered during the development of any future action under TSCA. 
Future actions under TSCA section 4 would go through notice and comment 
rulemaking or be negotiated as voluntary testing enforcement 
agreements/consent orders/decrees, allowing for additional public 
comment on this issue. Nevertheless, the Agency is interested in 
whether or not there are any voluntary consensus standards that EPA 
should considered in leu of these test guidelines when the Agency 
develops any future regulatory action that incorporates these test 
guidelines. Any comments provided will assist the Agency in complying 
with the NTTAA by facilitating the Agency's identification of voluntary 
consensus standards that should be considered during the development of 
a proposed regulatory action that incorporates any standards included 
in these test guidelines. Please submit your comments to the technical 
person for TSCA that is identified in the ``FOR FURTHER INFORMATION 
CONTACT'' section at the beginning of this document.
