Background The Office of Prevention, Pesticides and Toxic Substances (OPPTS) has a unified library of harmonized test guidelines that are made available for use in the testing of pesticides and toxic substances, and the development of test data to meet the data requirements of the Agency or for voluntary testing purposes. Test guidelines are documents that specify methods that EPA recommends be used to generate data to support the registration of a pesticide, setting of a tolerance or tolerance exemption for pesticide residues, or the decisionmaking process for an industrial chemical. These data are used by the Agency to perform risk assessments and make regulatory decisions. Studies conducted according to these test guidelines may be required under FIFRA (7 U.S.C. 136) for pesticide registration. The test guidelines may also be useful for satisfying FIFRA data requirements in 40 CFR part 158, datacall-ins issued pursuant to FIFRA section 3(c)(2)(B), as needed to satisfy data requirements appropriate for specific pesticide registration applications, or for satisfying data requirements to demonstrate the safety of a tolerance or tolerance exemption under FFDCA section 408 (21 U.S.C. 346a). Test guidelines used in regulatory actions as bases for test standards under TSCA (15 U.S.C. 2601) are typically promulgated in 40 CFR part 799, or may be written into specific TSCA rules (such as test rules under TSCA section 4). The test guidelines may also be used as part of voluntary testing. Note that where data will be required under a TSCA rule (such as a test rule under TSCA section 4), a TSCA-specific version of the applicable test guideline PO 00000 Frm 00034 Fmt 4703 Sfmt 4703 may be promulgated as a rule. Examples may be found at 40 CFR part 799, subparts E and H. III. What Action is EPA Taking? EPA is announcing the availability of several revised or updated test guidelines for the OPPTS unified library of harmonized test guidelines. Specifically, EPA is announcing the availability of revised test guidelines under Series 830–Product Performance Test Guidelines, Series 835–Fate, Transport and Transformation Test Guidelines, and Series 860–Residue Chemistry Test Guidelines. A. Updated Delivery Address in OPPTS Test Guidelines 830.1900 and 860.1650 The Agency is correcting the mailing addresses that appear in OPPTS Test Guideline 830.1900–Submittal of Samples and OPPTS Test Guideline 860.1650–Submittal of Analytical Reference Standards because the test guidelines, which were issued in August 1996, reference addresses that have since changed due to facility moves. B. Supplemental Guidance for OPPTS Test Guideline 860.1000 In June 2008, the Agency announced the release of revisions of Table 1 feedstuffs of OPPTS Test Guideline 860.1000–Background and the availability of guidance to aid reviewers in the construction of livestock diets adjusted for today’s commercial practices. The changes in Table 1 include revised definitions of reference animals, updated percentages of feedstuffs in livestock diets, reduction of the ‘‘Nu (not used)’’ level to <5% of the diet, a list of alternative feedstuffs, and classification of feedstuffs into three categories (roughage [R], carbohydrate concentrate [CC], protein concentrate [PC]). The guidance on ‘‘maximum reasonably balanced diets’’ (MRBD) represents a shift from the past practice of using ‘‘maximum theoretical dietary burdens’’ (MTDB) to assess maximum potential residues in livestock commodities. The revised data for Table 1 feedstuffs and use of MRBD are to be implemented immediately. If this revised table is referenced in any memorandum, it should be cited as: ‘‘Table 1 Feedstuffs (June 2008).’’ There have been no changes made with regard to the human foods in Table 1 as of this time. Therefore, the raw agricultural commodities (RACs) and processed commodities which are not livestock feeds remain as specified in Table 1 of OPPTS Test Guideline 860.1000 (published in 1996). E:\FR\FM\15APN1.SGM 15APN1 Federal Register / Vol. 74, No. 71 / Wednesday, April 15, 2009 / Notices C. Updated OPPTS Test Guidelines for Series 835 EPA is announcing the availability of updated test guidelines for the OPPTS Test Guideline Series 835–Fate, Transport and Transformation Test Guidelines. Many of these guidelines are based upon, and bring up to date, the 1982 Pesticide Assessment Guidelines–Subdivision N protocols that were presented to the Scientific Advisory Panel (SAP) in the late 1970s and are currently being used to perform environmental fate testing to support the registration of pesticides under FIFRA. These test guidelines are a [nonregulatory] companion to 40 CFR Part 158–Pesticides; Data Requirement for Conventional Chemicals. Eight such Subdivision N guidelines have been reformatted, including insertion of clarifying guidance, and assigned an OPPTS 835 designation. The test guidelines in this group are: • 835.2240–Photodegradation in Water. • 835.2410–Photodegradation in Soil. • 835.2370–Photodegradation in Air. • 835.1410–Laboratory Volatility. • 835.8100–Field Volatility. • 835.6200–Aquatic (Sediment) Field Dissipation. • 835.6300–Forestry Dissipation. • 835.6400–Combination and Tank Mixes Field Dissipation. rwilkins on PROD1PC63 with PROPOSALS One Subdivision N guideline, 835.1240–Leaching Studies, has been updated based on the test guideline harmonization efforts of the Organization for Economic Cooperation and Development (OECD). The Office of Pesticide Programs (OPP) played a major role in the OECD harmonization effort. Six test guidelines were harmonized at OECD for use with pesticides or industrial chemicals: Both OPP and the Office of Pollution Prevention and Toxics (OPPT) played major roles in the OECD harmonization effort. The test guidelines in this group are: • 835.2120–Hydrolysis. • 835.4100–Aerobic Soil Metabolism. • 835.4200–Anaerobic Soil Metabolism. • 835.4300–Aerobic Aquatic Metabolism. • 835.4400–Anaerobic Aquatic Metabolism. • 835.1230–Adsorption/Desorption (Batch Equilibrium). OPPTS 835.2120 supersedes OPPTS 835.2110–Hydrolysis as a Function of pH. The test guideline for Terrestrial Field Dissipation (OPPTS 835.6100) is the result of a harmonization effort with VerDate Nov<24>2008 16:44 Apr 14, 2009 Jkt 217001 Canada’s Pest Management Regulatory Agency (PMRA) and was completed under the auspices of the North American Free Trade Agreement (NAFTA) Technical Working Group on Pesticides, established under NAFTA. This guideline was peer-reviewed by FIFRA SAP. OPPT has played a key role in the OECD harmonization effort responsible for eight other OPPTS 835 Series guidelines, for testing of industrial chemicals. The eight test guidelines are: • 835.0001–Principles and Strategies Related to Biodegradation Testing of Organic Chemicals under the Toxic Substances Control Act (TSCA). • 835.3140–Ready Biodegradability— CO2 in Sealed Vessels (Headspace Test). • 835.3190–Aerobic Mineralization in Surface Water—Simulation Biodegradation Test. • 835.3215–Inherent Biodegradability—Concawe Test. • 835.3240–Simulation Test—Aerobic Sewage Treatment: A. Activated Sludge Units. • 835.3260–Simulation Test—Aerobic Sewage Treatment: B. Biofilms. • 835.3280–Simulation Tests to Assess the Primary and Ultimate Biodegradability of Chemicals Discharged to Wastewater. • 835.3420–Anaerobic Biodegradability of Organic Compounds in Digested Sludge: By Measurement of Gas Production. Of these eight test guidelines, three are updated versions that supersede existing OPPTS guidelines. The three are OPPTS 835.3140 (supersedes OPPTS 835.3120–Sealed-Vessel CO2 Production Test); OPPTS 835.3240 (supersedes OPPTS 835.3220–Porous Pot Test); and OPPTS 835.3420 (supersedes OPPTS 835.3400–Anaerobic Biodegradability of Organic Chemicals). The other five test guidelines are also based on the test guideline harmonization efforts of OECD, but reflect the development of new test methods that has occurred since the OPPTS 835 Series guidelines for industrial chemicals were last updated in the 1990s. In addition to these five, OPPTS 835.4100, 835.4200, 835.4300, and 835.4400 are similarly based on OECD test methods developed and adopted since the mid 1990s.

II. Background

    The Office of Prevention, Pesticides and Toxic Substances (OPPTS) 
has a unified library of harmonized test guidelines that are made 
available for use in the testing of pesticides and toxic substances, 
and the development of test data to meet the data requirements of the 
Agency or for voluntary testing purposes. Test guidelines are documents 
that specify methods that EPA recommends be used to generate data to 
support the registration of a pesticide, setting of a tolerance or 
tolerance exemption for pesticide residues, or the decisionmaking 
process for an industrial chemical. These data are used by the Agency 
to perform risk assessments and make regulatory decisions.
    Studies conducted according to these test guidelines may be 
required under FIFRA (7 U.S.C. 136) for pesticide registration. The 
test guidelines may also be useful for satisfying FIFRA data 
requirements in 40 CFR part 158, data-call-ins issued pursuant to FIFRA 
section 3(c)(2)(B), as needed to satisfy data requirements appropriate 
for specific pesticide registration applications, or for satisfying 
data requirements to demonstrate the safety of a tolerance or tolerance 
exemption under FFDCA section 408 (21 U.S.C. 346a).
    Test guidelines used in regulatory actions as bases for test 
standards under TSCA (15 U.S.C. 2601) are typically promulgated in 40 
CFR part 799, or may be written into specific TSCA rules (such as test 
rules under TSCA section 4). The test guidelines may also be used as 
part of voluntary testing. Note that where data will be required under 
a TSCA rule (such as a test rule under TSCA section 4), a TSCA-specific 
version of the applicable test guideline may be promulgated as a rule. 
Examples may be found at 40 CFR part 799, subparts E and H.

III. What Action is EPA Taking?

    EPA is announcing the availability of several revised or updated 
test guidelines for the OPPTS unified library of harmonized test 
guidelines. Specifically, EPA is announcing the availability of revised 
test guidelines under Series 830-Product Performance Test Guidelines, 
Series 835-Fate, Transport and Transformation Test Guidelines, and 
Series 860-Residue Chemistry Test Guidelines.

A. Updated Delivery Address in OPPTS Test Guidelines 830.1900 and 
860.1650

    The Agency is correcting the mailing addresses that appear in OPPTS 
Test Guideline 830.1900-Submittal of Samples and OPPTS Test Guideline 
860.1650-Submittal of Analytical Reference Standards because the test 
guidelines, which were issued in August 1996, reference addresses that 
have since changed due to facility moves.

B. Supplemental Guidance for OPPTS Test Guideline 860.1000

    In June 2008, the Agency announced the release of revisions of 
Table 1 feedstuffs of OPPTS Test Guideline 860.1000-Background and the 
availability of guidance to aid reviewers in the construction of 
livestock diets adjusted for today's commercial practices. The changes 
in Table 1 include revised definitions of reference animals, updated 
percentages of feedstuffs in livestock diets, reduction of the ``Nu 
(not used)'' level to <5% of the diet, a list of alternative 
feedstuffs, and classification of feedstuffs into three categories 
(roughage [R], carbohydrate concentrate [CC], protein concentrate 
[PC]). The guidance on ``maximum reasonably balanced diets'' (MRBD) 
represents a shift from the past practice of using ``maximum 
theoretical dietary burdens'' (MTDB) to assess maximum potential 
residues in livestock commodities. The revised data for Table 1 
feedstuffs and use of MRBD are to be implemented immediately. If this 
revised table is referenced in any memorandum, it should be cited as: 
``Table 1 Feedstuffs (June 2008).'' There have been no changes made 
with regard to the human foods in Table 1 as of this time. Therefore, 
the raw agricultural commodities (RACs) and processed commodities which 
are not livestock feeds remain as specified in Table 1 of OPPTS Test 
Guideline 860.1000 (published in 1996).

[[Page 17481]]

C. Updated OPPTS Test Guidelines for Series 835

    EPA is announcing the availability of updated test guidelines for 
the OPPTS Test Guideline Series 835-Fate, Transport and Transformation 
Test Guidelines. Many of these guidelines are based upon, and bring up 
to date, the 1982 Pesticide Assessment Guidelines-Subdivision N 
protocols that were presented to the Scientific Advisory Panel (SAP) in 
the late 1970s and are currently being used to perform environmental 
fate testing to support the registration of pesticides under FIFRA. 
These test guidelines are a [non-regulatory] companion to 40 CFR Part 
158-Pesticides; Data Requirement for Conventional Chemicals. Eight such 
Subdivision N guidelines have been reformatted, including insertion of 
clarifying guidance, and assigned an OPPTS 835 designation. The test 
guidelines in this group are:

     835.2240-Photodegradation in Water.
     835.2410-Photodegradation in Soil.
     835.2370-Photodegradation in Air.
     835.1410-Laboratory Volatility.
     835.8100-Field Volatility.
     835.6200-Aquatic (Sediment) Field Dissipation.
     835.6300-Forestry Dissipation.
     835.6400-Combination and Tank Mixes Field Dissipation.

    One Subdivision N guideline, 835.1240-Leaching Studies, has been 
updated based on the test guideline harmonization efforts of the 
Organization for Economic Cooperation and Development (OECD). The 
Office of Pesticide Programs (OPP) played a major role in the OECD 
harmonization effort.
    Six test guidelines were harmonized at OECD for use with pesticides 
or industrial chemicals: Both OPP and the Office of Pollution 
Prevention and Toxics (OPPT) played major roles in the OECD 
harmonization effort. The test guidelines in this group are:

     835.2120-Hydrolysis.
     835.4100-Aerobic Soil Metabolism.
     835.4200-Anaerobic Soil Metabolism.
     835.4300-Aerobic Aquatic Metabolism.
     835.4400-Anaerobic Aquatic Metabolism.
     835.1230-Adsorption/Desorption (Batch Equilibrium).

    OPPTS 835.2120 supersedes OPPTS 835.2110-Hydrolysis as a Function 
of pH.
    The test guideline for Terrestrial Field Dissipation (OPPTS 
835.6100) is the result of a harmonization effort with Canada's Pest 
Management Regulatory Agency (PMRA) and was completed under the 
auspices of the North American Free Trade Agreement (NAFTA) Technical 
Working Group on Pesticides, established under NAFTA. This guideline 
was peer-reviewed by FIFRA SAP.
    OPPT has played a key role in the OECD harmonization effort 
responsible for eight other OPPTS 835 Series guidelines, for testing of 
industrial chemicals. The eight test guidelines are:

     835.0001-Principles and Strategies Related to 
Biodegradation Testing of Organic Chemicals under the Toxic Substances 
Control Act (TSCA).
     835.3140-Ready Biodegradability--CO2 in Sealed 
Vessels (Headspace Test).
     835.3190-Aerobic Mineralization in Surface Water--
Simulation Biodegradation Test.
     835.3215-Inherent Biodegradability--Concawe Test.
     835.3240-Simulation Test--Aerobic Sewage Treatment: A. 
Activated Sludge Units.
     835.3260-Simulation Test--Aerobic Sewage Treatment: B. 
Biofilms.
     835.3280-Simulation Tests to Assess the Primary and 
Ultimate Biodegradability of Chemicals Discharged to Wastewater.
     835.3420-Anaerobic Biodegradability of Organic Compounds 
in Digested Sludge: By Measurement of Gas Production.

    Of these eight test guidelines, three are updated versions that 
supersede existing OPPTS guidelines. The three are OPPTS 835.3140 
(supersedes OPPTS 835.3120-Sealed-Vessel CO2 Production 
Test); OPPTS 835.3240 (supersedes OPPTS 835.3220-Porous Pot Test); and 
OPPTS 835.3420 (supersedes OPPTS 835.3400-Anaerobic Biodegradability of 
Organic Chemicals). The other five test guidelines are also based on 
the test guideline harmonization efforts of OECD, but reflect the 
development of new test methods that has occurred since the OPPTS 835 
Series guidelines for industrial chemicals were last updated in the 
1990s. In addition to these five, OPPTS 835.4100, 835.4200, 835.4300, 
and 835.4400 are similarly based on OECD test methods developed and 
adopted since the mid 1990s.
