SUPPLEMENTARY INFORMATION: International Specialty Products, 1361 Alps 
Road, Wayne, NJ 07470, submitted pesticide petition (PP) 6E04659 to EPA 
requesting that the Administrator, pursuant to section 408(e) of the 
Federal Food Drug, and Cosmetic Act (FFDCA) (21 U.S.C. 346 a(e)), 
propose to amend 40 CFR part 180.1001(c) and (e) by establishing an 
exemption from the requirement of tolerance for residues of vinyl 
pyrrolidone-acrylic acid copolymer (CAS Reg. No. 28062-44-4), when used 
as an inert ingredient (adhesive, dispersion stabilizer and coating for 
sustained release granules) in pesticide formulations applied to 
growing crops or to raw agricultural commodities after harvest, under 
40 CFR 180.1001(c) and applied to animals under 40 CFR 180.1001(e).
    Inert ingredients are all ingredients that are not active 
ingredients as defined in 40 CFR 153.125, and include, but are not 
limited to, the following types of ingredients (except when they have a 
pesticidal efficacy of their own): solvents such as alcohols and 
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty 
acids; carriers such as clay and diatomaceous earth; thickeners such as 
carrageenan and modified cellulose; wetting, spreading, and dispersing 
agents; propellants in aerosol dispensers; microencapsulating agents; 
and emulsifiers. The term ``inert'' is not to imply nontoxicity; the 
ingredient may or may not be chemically active.
    The data submitted in the petition and other relevant material have 
been evaluated. As part of the EPA policy statement on inert 
ingredients published in the Federal Register of April 22, 1987 (52 FR 
13305), the Agency set forth a list of studies which would generally be 
used to evaluate the risks posed by the presence of an inert ingredient 
in a pesticide formulation. However, where it can be determined without 
that data that the inert ingredient will present

[[Page 30203]]

minimal or no risk, the Agency generally does not require some or all 
of the listed studies to rule on the proposed tolerance or exemption 
from the requirement of a tolerance for an inert ingredient. The Agency 
has decided that no data, in addition to that described below, for 
vinyl pyrrolidone-acrylic acid copolymer will need to be submitted. The 
rationale for this decision is described below.
    In the case of certain chemical substances that are defined as 
``polymers,'' the Agency has established a set of criteria which 
identify categories of polymers that present low risk. These criteria 
(described in 40 CFR 723.250) identify polymers that are relatively 
unreactive and stable compared to other chemical substances as well as 
polymers that typically are not readily absorbed. These properties 
generally limit a polymer's ability to cause adverse effects. In 
addition, these criteria exclude polymers about which little is known. 
The Agency believes that polymers meeting the criteria noted above will 
present minimal or no risk. Vinyl pyrrolidone-acrylic acid copolymer 
conforms to the definition of polymer given in 40 CFR 723.250(b) and 
meets the following criteria that are used to identify low risk 
polymers:
    1. Vinyl pyrrolidone-acrylic acid copolymer is not a cationic 
polymer, nor is it reasonably anticipated to become a cationic polymer 
in a natural aquatic environment.
    2. Vinyl pyrrolidone-acrylic acid copolymer contains as an integral 
part of its composition the atomic elements carbon, hydrogen, oxygen 
and nitrogen.
    3. Vinyl pyrrolidone-acrylic acid copolymer does not contain as an 
integral part of its composition, except as impurities, any elements 
other than those listed in 40 CFR 723.250(d)(2)(ii).
    4. Vinyl pyrrolidone-acrylic acid copolymer is not designed, nor it 
is reasonably anticipated to substantially degrade, decompose or 
depolymerize.
    5. Vinyl pyrrolidone-acrylic acid copolymer is not manufactured or 
imported from monomers and /or other reactants that are not already 
included on the TSCA Chemical Substance Inventory or manufactured under 
an applicable TSCA section 5 exemption.
    6. Vinyl pyrrolidone-acrylic acid copolymer contains only 
carboxylic acid groups as reactive functional groups.
    7. The minimum number-average molecular weight of vinyl 
pyrrolidone-acrylic acid copolymer is listed as 6,900 daltons. 
Substances with molecular weights greater than 400 generally are not 
absorbed through the intact skin, and substances with molecular weights 
greater than 1,000 generally are not absorbed through the intact 
gastrointestinal (GI) tract. Chemicals not absorbed through the skin or 
GI tract generally are incapable of eliciting a toxic response.
    8. Vinyl pyrrolidone-acrylic acid copolymer has a number average 
molecular weight of 6,900 and contains less than 10 percent oligomeric 
material below molecular weight 500 and less than 25 percent oligomeric 
material below 1,000 molecular weight. Based upon the above information 
and review of its use, EPA has found that, when used in accordance with 
good agricultural practice, this ingredient is useful and tolerance is 
not necessary to protect the public health. Therefore, EPA proposes 
that the exemptions from the requirement of a tolerance be established 
for this polymer as set forth below.
    Any person who has registered or submitted an application for 
registration of a pesticide, under the Federal Insecticide, Fungicide, 
and Rodenticide Act (FIFRA) as amended, that contains any of the 
ingredients listed herein, may request within 30 days after the 
publication of this document in the Federal Register that this 
rulemaking proposal be referred to an Advisory Committee in accordance 
with section 408(e) of the FFDCA.
    Interested persons are invited to submit written comments on the 
proposed regulation. Comments must bear a notation indicating the 
docket number, [OPP-300426].
    A record has been established for this rulemaking under docket 
number [OPP-300426] (including comments and data submitted 
electronically as described below). A public version of this record, 
including printed paper versions of electronic comments, which does not 
include any information claimed as CBI, is available for inspection 
from 8 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays. The public record is located in Room 1132 of the Public 
Response and Program Resources Branch, Field Operations Division 
(7506C), Office of Pesticide Programs, Environmental Protection Agency, 
Crystal Mall #2, 1921 Jefferson Davis Highway, Arlington, VA.
    Electronic comments can be sent directly to EPA at:
    opp-D[email protected]


    Electronic comments must be submitted as an ASCII file avoiding the 
use of special characters and any form of encryption.
    The official record for this rulemaking, as well as the public 
version, as described above will be kept in paper form. Accordingly, 
EPA will transfer all comments received electronically into printed, 
paper form as they are received and will place the paper copies in the 
official rulemaking record which also will include all comments 
submitted directly in writing. The official rulemaking record is the 
paper record maintained at the address in the ``ADDRESSES'' at the 
beginning of this document.
    The Office of Management and Budget has exempted this rule from the 
requirements of section 2 of Executive Order 12866.
    This action does not impose any enforceable duty, or contain any 
``unfunded mandates'' as described in Title II of the Unfunded Mandates 
Reform Act of 1995 (Pub. L. 104-4), or require prior consultation as 
specified by Executive Order 12875 (58 FR 58093, October 28, 1993), 
entitled Enhancing the Intergovernmental Partnership, or special 
consideration as required by Executive Order 12898 (59 FR 7629, 
February 16, 1994).
    Pursuant to the requirement of the Regulatory Flexibility Act (Pub. 
L. 96-354, 94 Stat. 1164, 5 U.S.C. 601-612), the Administrator has 
determined that regulations establishing new tolerances or raising 
tolerance levels or establishing exemptions from tolerance requirements 
do not have an economic impact on a substantial number of small 
entities. A certification statement to this effect was published in the 
Federal Register of May 4, 1981 (46 FR 24950).
