ENVIRONMENTAL PROTECTION AGENCY
[OPP-00385; FRL-4898-2]

 

Publication of Addenda for Data Reporting; Requirements for 
Pesticide Assessment Guidelines (N, E, and K)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability; request for comment.

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

SUMMARY: This notice announces the availability of and requests 
comments regarding the proposed addenda which includes a draft Data 
Reporting Guidelines (DRG) for those environmental chemistry methods 
associated with Subdivision N, E, and K. This draft DRG is not intended 
to introduce any new data requirements or revisions into the existing 
guidelines. Its purpose is to further clarify technical aspects of the 
existing Pesticide Assessment Guidelines and to provide a format for 
organizing and submitting soil and water methods and their supporting 
data in order to facilitate their review. EPA recognizes there are 
sections of the draft DRG that do not apply to specific soil and water 
methods; therefore, registrants should exercise scientific judgement in 
deciding which sections apply to their methods.

DATES: Three copies of written comments must be received by Donald A. 
Marlow identified below on or before August 22, 1994.

ADDRESSES: The draft Data Reporting Guideline for the Pesticide 
Assessment Guidelines (N, E, and K) can be obtained from the pesticide 
public docket at the following address: Public Response and Program 
Resources Branch, Field Operations Division (7506C), Office of 
Pesticide Programs, Environmental Protection Agency, 401 M St., SW., 
Washington, DC 20460. In person or by telephone: Rm. 1132, Crystal Mall 
#2, 1921 Jefferson Davis Highway, Arlington, VA 22202 (703) 305-5805.

FOR FURTHER INFORMATION CONTACT: Donald A. Marlow, Chief, Analytical 
Chemistry Branch (7503W), Biological and Economic Analysis Division, 
Office of Pesticide Programs, Environmental Protection Agency, 401 M 
St., SW., Washington, DC 20460. Office location and telephone number: 
Crystal Station 1, Rm. CS 44J1, 2800 Crystal Drive, Arlington, VA 
22203, (703) 308-8198 (Voice Mail).

SUPPLEMENTARY INFORMATION: The draft DRG provides the registrant with a 
detailed format for submitting soil and water methods to the Agency. 
Each method should be complete and meet the technical requirements 
identified in the DRG. Those methods should be sent to the Agency to 
support specific exposure, environmental fate, and ecological effects 
studies during the normal registration and reregistration cycle. Each 
study for which environmental chemistry methods are needed has been 
clearly identified below. Soil and water methods should be clearly 
written and capable of being repeated by chemists in Federal and state 
laboratories.
    The draft DRG is not intended to introduce any requirements. Its 
purpose is to further clarify technical aspects of the existing 
Pesticide Assessment Guidelines and to provide a format for organizing 
and submitting soil and water methods used to generate study data and 
to facilitate their review. The studies involved are:
    Subdivision N -   Environmental Fate

    Series 164-1 -   Terrestrial Field Dissipation Studies 1
    Series 164-2 -   Aquatic Field Dissipation Studies
    Series 164-3 -   Forest Field Dissipation Studies
    Series 164-5 -   Long Term Soil Dissipation Studies 1
---------------------------------------------------------------------------

    \ \In practice these studies are considered to be equivalent 
because they evaluate the persistent nature of pesticide residues in 
soil.
---------------------------------------------------------------------------

    Series 165-3 -   Accumulation Studies in Irrigation Crops
    Series 166-1 -   Groundwater Study

    Subdivision E -   Hazard Evaluation
    Series 71-5 -   Simulated and Actual Field Testing for Mammals 
and Birds
    Series 72-7 -   Simulated and Actual Field Testing and Aquatic 
Organisms

    Subdivision K -   Reentry Protection

    Series 132-1 -   Soil Dislodgeable Residue Dissipation Studies

    These addenda supercede the paragraphs in the respective guidelines 
and the other addenda issued by the Pesticide Program regarding soil 
and water methods sent to the Agency for the studies identified above.
    While these addenda to the Guidelines are not mandatory, data 
submitters are strongly encouraged to follow the format to assure that 
reports will be consistent, thereby increasing the efficiency of 
pesticide registration, reregistration, and other regulatory 
activities.
    This is the ninth addendum to Subdivision N-Environmental Fate 
(Chemistry) published by the Agency. This new addenda with the draft 
DRG has been sent to the U.S. Department of Agriculture, the Food and 
Drug Administration, and other organizations within EPA for comment. 
With this notice EPA plans to make the DRG available to the public for 
comment in the Federal Register.
    The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) 
requires the registration of all pesticides that are manufactured for 
use in the United States. In order to obtain a registration from EPA, 
manufacturers must demonstrate that their pesticides do not cause any 
unreasonable adverse effects to human health and the environment. It is 
now considered appropriate to provide available soil and water residue 
methods to EPA because of the increased public concern regarding the 
contamination of the environment with pesticides. EPA will validate 
some of those methods and may assemble them into a new manual in order 
to make them available to address potential environmental problems. 
This DRG provides more detailed technical guidance regarding those 
analytical methods and amends Pesticide Assessment Guideline N, E, and 
K referred to earlier.
    These methods may be validated in an EPA laboratory to determine if 
they identify and quantify the pesticide parent compound, 
toxicologically significant metabolites, and degradates at the level 
indicated. The results from the soil and water method validation 
program may be used to support regulatory decisions regarding the 
reliability and validity of the chemistry data sent to the Agency with 
exposure, environmental fate, and ecological effects studies.
