SUPPLEMENTARY INFORMATION: Consep, Inc., 213 Southwest Columbia St., 
Bend, OR 97702-1013, submitted pesticide petition (PP) 4E04401 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(d) by exempting cellulose acetate 
from the requirement of a tolerance. Cellulose acetate, when used as an 
inert ingredient (pesticide rate-release regulating agent) in pesticide 
formulations applied to growing crops only, under 40 CFR 180.1001(d), 
meets the definition of a polymer under 40 CFR 723.250(b) and the 
criteria listed in 40 CFR 723.250(e) that define a chemical substance 
that poses no unreasonable risk under section 5 of the Toxic Substance 
Control Act (TSCA).
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 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 cellulose acetate 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. Cellulose Acetate conforms to the definition 
of a polymer given in 40 CFR 723.250(b) and meets the following criteria 
that are used to identify low-risk polymers. 
1. The minimum number average molecular weight of cellulose acetate is 
28,000. Substances with molecular weights greater than 400 generally are

[[Page 43739]]
not absorbed through the intact skin, and substances with molecular 
weights greater than 1,000 generally are not absorbed through the intact 
gastrointestinal tract. Chemicals not absorbed through skin or GI tract 
generally are incapable of eliciting a toxic response. 
2. Cellulose acetate is not a cationic polymer, nor is it reasonably 
expected to become a cationic polymer in a natural aquatic environment.
3. Cellulose acetate does not contain less than 32.0 percent by weight 
of the atomic element carbon.
4. Cellulose acetate contains as an integral part of its composition the 
atomic elements carbon, hydrogen, and oxygen. 
5. Cellulose acetate 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).
6. Cellulose acetate is not a biopolymer, a synthetic equivalent of a 
biopolymer, or a derivative or modification of a biopolymer that is 
substantially intact.
7. Cellulose acetate is not manufactured from reactants containing, 
other than as impurities, halogen atoms or cyano groups. 
8. Cellulose acetate does not contain reactive functional groups that 
are intended or reasonably expected to undergo further reaction. 
9. Cellulose acetate is neither designed nor reasonably expected to 
substantially degrade, decompose, or depolymerize. 
Based on the information above and review of its use, EPA has found 
that, when used in accordance with good agricultural practice, this 
ingredient is useful, and a tolerance is not necessary to protect the 
public health. Therefore, EPA proposes that the exemption from the 
requirement of a tolerance be established 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 
document control number, [OPP-300395]. All written comments filed in 
response to this petition will be available in the Public Response and 
Program Resources Branch, at the address given above, from 8 a.m. to 4 
p.m., Monday through Friday, except legal holidays. 
A record has been established for this rulemaking under docket number 
[OPP-300395] (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-
Docket@epamail.epa.gov

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 will also include all comments submitted 
directly in writing. The official rulemaking record is the paper record 
maintained at the address in ``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. 
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).
