40 CFR Part 180

[OPP-2003-0121; FRL-7302-2]


Pesticides; Tolerance Exemptions for Active and Inert Ingredients 
for Use in Antimicrobial Formulations (Food-Contact Surface Sanitizing 
Solutions)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to add a new section to part 180 which lists 
the pesticide chemicals that are exempt from the requirement of a 
tolerance when used in food-contact surface sanitizing solutions. The 
initial list of exempt pesticide chemicals in the new section is 
duplicated from the Food and Drug Administration's (FDA) regulations in 
21 CFR 178.1010. EPA is also changing FDA's naming conventions for some 
of the chemical substances that were duplicated.
    Until recently, FDA under the Federal Food, Drug, and Cosmetic Act 
(FFDCA) section 409, regulated food-contact surface sanitizing 
solutions. With the amendments to FFDCA by the Food Quality Protection 
Act (FQPA) of 1996 and by the Antimicrobial Regulation Technical 
Corrections Act (ARTCA) of 1998, these responsibilities have been 
restructured. Under FFDCA section 408, EPA will now regulate the 
pesticide uses of these chemical substances and FDA under FFDCA section 
409 will continue to regulate any indirect food additive uses of these 
chemical substances.
    Registrants of existing food-contact surface sanitizing solutions 
that contain chemical substances other than those listed in this 
proposed rule should identify these chemical substances and support 
their claim that the chemical substance is generally recognized as safe 
(GRAS), or permitted by FDA prior sanction, or approval, or subject to 
a letter of no objection in order to remain exempt from the requirement 
of a FFDCA section 408 tolerance.

DATES: Comments, identified by docket ID number OPP-2003-0121, must be 
received on or before July 25, 2003.
    Registrants should identify chemical substances not listed in this 
document and support their claims of GRAS, or prior sanction, or 
approval, or no objection of these chemical substances by submission of 
such information to the person listed under FOR FURTHER INFORMATION, on 
or before October 1, 2003.

ADDRESSES: Comments may be submitted electronically, by mail, or 
through hand delivery/courier. Follow the detailed instructions as 
provided in Unit I. of the SUPPLEMENTARY INFORMATION.
    Registrants identifying chemical substances not listed in this 
document and the supporting documentation for their claims of GRAS, or 
prior sanction, or approval, or no objection of these chemical 
substances for inclusion in 40 CFR 180.940 should submit the 
information directly to the person listed under FOR FURTHER 
INFORMATION.

 Identification of a chemical substance is not a comment and should be 
identified as ``Submission of Non-designated Prior Approved 
Substance.''

printed, paper form in the official public docket. To the extent 
feasible, publicly available docket materials will be made available in 
EPA's electronic public docket. When a document is selected from the 
index list in EPA Dockets, the system will identify whether the 
document is available for viewing in EPA's electronic public docket. 
Although not all docket materials may be available electronically, you 
may still access any of the publicly available docket materials through 
the docket facility identified in Unit I.B.1. EPA intends to work 
towards providing electronic access to all of the publicly available 
docket materials through EPA's electronic public docket.
    For public commenters, it is important to note that EPA's policy is 
that public comments, whether submitted electronically or in paper, 
will be made available for public viewing in EPA's electronic public 
docket as EPA receives them and without change, unless the comment 
contains copyrighted material, CBI, or other information whose 
disclosure is restricted by statute. When EPA identifies a comment 
containing copyrighted material, EPA will provide a reference to that 
material in the version of the comment that is placed in EPA's 
electronic public docket. The entire printed comment, including the 
copyrighted material, will be available in the public docket.
    Public comments submitted on computer disks that are mailed or 
delivered to the docket will be transferred to EPA's electronic public 
docket. Public comments that are mailed or delivered to the docket will 
be scanned and placed in EPA's electronic public docket. Where 
practical, physical objects will be photographed, and the photograph 
will be placed in EPA's electronic public docket along with a brief 
description written by the docket staff.

C. How and To Whom Do I Submit Comments?

    You may submit comments electronically, by mail, or through hand 
delivery/courier. To ensure proper receipt by EPA, identify the 
appropriate docket ID number in the subject line on the first page of 
your comment. Please ensure that your comments are submitted within the 
specified comment period. Comments received after the close of the 
comment period will be marked ``late.'' EPA is not required to consider 
these late comments. If you wish to submit CBI or information that is 
otherwise protected by statute, please follow the instructions in Unit 
I.D. Do not use EPA Dockets or e-mail to submit CBI or information 
protected by statute.
    1. Electronically. If you submit an electronic comment as 
prescribed in this unit, EPA recommends that you include your name, 
mailing address, and an e-mail address or other contact information in 
the body of your comment. Also include this contact information on the 
outside of any disk or CD ROM you submit, and in any cover letter 
accompanying the disk or CD ROM. This ensures that you can be 
identified as the submitter of the comment and allows EPA to contact 
you in case EPA cannot read your comment due to technical difficulties 
or needs further information on the substance of your comment. EPA's 
policy is that EPA will not edit your comment, and any identifying or 
contact information provided in the body of a comment will be included 
as part of the comment that is placed in the official public docket, 
and made available in EPA's electronic public docket. If EPA cannot 
read your comment due to technical difficulties and cannot contact you 
for clarification, EPA may not be able to consider your comment.
    i. EPA Dockets. Your use of EPA's electronic public docket to 
submit comments to EPA electronically is EPA's preferred method for 
receiving comments. Go directly to EPA Dockets at http://www.epa.gov/edocket, and

[[Page 37780]]

follow the online instructions for submitting comments. Once in the 
system, select ``search,'' and then key in docket ID number OPP-2003-
0121. The system is an ``anonymous access'' system, which means EPA 
will not know your identity, e-mail address, or other contact 
information unless you provide it in the body of your comment.
    ii. E-mail. Comments may be sent by e-mail to: [email protected], 
Attention: Docket ID Number OPP-2003-0121. In contrast to EPA's 
electronic public docket, EPA's e-mail system is not an ``anonymous 
access'' system. If you send an e-mail comment directly to the docket 
without going through EPA's electronic public docket, EPA's e-mail 
system automatically captures your e-mail address. E-mail addresses 
that are automatically captured by EPA's e-mail system are included as 
part of the comment that is placed in the official public docket, and 
made available in EPA's electronic public docket.
    iii. Disk or CD ROM. You may submit comments on a disk or CD ROM 
that you mail to the mailing address identified in Unit I.C.2. These 
electronic submissions will be accepted in WordPerfect or ASCII file 
format. Avoid the use of special characters and any form of encryption.
    2. By mail. Send your comments to: Public Information and Records 
Integrity Branch (PIRIB) (7502C), Office of Pesticide Programs (OPP), 
Environmental Protection Agency, 1200 Pennsylvania Ave., NW., 
Washington, DC 20460-0001, Attention: Docket ID Number OPP-2003-0121.
    3. By hand delivery or courier. Deliver your comments to: Public 
Information and Records Integrity Branch (PIRIB), Office of Pesticide 
Programs (OPP), Environmental Protection Agency, Rm. 119, Crystal Mall 
2, 1921 Jefferson Davis Hwy., Arlington, VA, Attention: Docket 
ID Number OPP-2003-0121. Such deliveries are only accepted during the 
docket's normal hours of operation as identified in Unit I.B.1.

D. How Should I Submit CBI To the Agency?

    Do not submit information that you consider to be CBI 
electronically through EPA's electronic public docket or by e-mail. You 
may claim information that you submit to EPA as CBI by marking any part 
or all of that information as CBI (if you submit CBI on disk or CD ROM, 
mark the outside of the disk or CD ROM as CBI and then identify 
electronically within the disk or CD ROM the specific information that 
is CBI). Information so marked will not be disclosed except in 
accordance with procedures set forth in 40 CFR part 2.
    In addition to one complete version of the comment that includes 
any information claimed as CBI, a copy of the comment that does not 
contain the information claimed as CBI must be submitted for inclusion 
in the public docket and EPA's electronic public docket. If you submit 
the copy that does not contain CBI on disk or CD ROM, mark the outside 
of the disk or CD ROM clearly that it does not contain CBI. Information 
not marked as CBI will be included in the public docket and EPA's 
electronic public docket without prior notice. If you have any 
questions about CBI or the procedures for claiming CBI, please consult 
the person listed under FOR FURTHER INFORMATION CONTACT.

E. What Should I Consider as I Prepare My Comments for EPA?

    You may find the following suggestions helpful for preparing your 
comments:
    1. Explain your views as clearly as possible.
    2. Describe any assumptions that you used.
    3. Provide any technical information and/or data you used that 
support your views.
    4. If you estimate potential burden or costs, explain how you 
arrived at your estimate.
    5. Provide specific examples to illustrate your concerns.
    6. Offer alternatives.
    7. Make sure to submit your comments by the comment period deadline 
identified.
    8. To ensure proper receipt by EPA, identify the appropriate docket 
ID number in the subject line on the first page of your response. It 
would also be helpful if you provided the name, date, and Federal 
Register citation related to your comments.

II. What is the Agency's Authority for Taking this Action?

    This proposed rule is issued under FFDCA section 408, 21 U.S.C. 
346a, as amended by FQPA (Public Law 104-170), and ARTCA (Public Law 
105-324).
    Section 408 of FFDCA authorizes the establishment of tolerances, 
exemptions from the requirement of a tolerance, modifications in 
tolerances, and revocation of tolerances for residues of pesticide 
chemicals in or on raw agricultural commodities and processed foods. 
Section 408(j)(2) of FFDCA provides that all regulations issued by FDA 
under FFDCA section 409 that stated conditions for safe use of 
substances that are now, post-FQPA, considered pesticide chemical 
residues in or on processed food or that otherwise stated the 
conditions under which such pesticide chemicals could be safely used, 
shall be deemed to be regulations issued under FFDCA section 408.
    Due to the FQPA and ARTCA amendments to FFDCA, those chemical 
substances originally regulated by FDA under FFDCA section 409 as food-
contact surface sanitizing solutions are now the responsibility of EPA. 
These pesticide chemical regulations are now subject to modification or 
revocation at EPA's initiative under FFDCA section 408(e). The Agency 
is proposing to duplicate the substance of FDA's food additive 
regulations for those chemical substances found in 21 CFR 178.1010 
which are now pesticide tolerance exemptions in a format consistent 
with EPA's authority under section 408 in a new section, 40 CFR 
180.940.
    EPA's rulemaking activity will have no effect on any of the FDA 
regulated FFDCA section 409 food additive regulations in 21 CFR 
178.1010.

III. Summary of this Action

A. Why is There an Overlap of EPA's and FDA's Regulatory Authorities?

    Since EPA was created in 1970, EPA and FDA have shared authority 
under FFDCA over pesticide chemical residues in food. Enactment of FQPA 
in 1996 amended FFDCA, and shifted to EPA regulatory authority over 
certain pesticide residues which were previously subject to FDA 
authority. Prior to 1996, products used to sanitize or disinfect 
permanent or semi-permanent food-contact surfaces were regulated by FDA 
as indirect food additives under FFDCA section 409. Under the FQPA and 
ARTCA amendments to FFDCA, antimicrobial formulations used on permanent 
or semi-permanent food-contact surfaces other than food packaging are 
now considered ``pesticide chemicals'' and are regulated by EPA under 
FFDCA section 408.
    FQPA added a provision to FFDCA to assure an orderly transition to 
the new regulatory system. Section 408(j)(2) of FFDCA provides that all 
food additive regulations issued under FFDCA section 409 prior to the 
enactment of FQPA for antimicrobial uses that became pesticide chemical 
uses subsequent to FQPA and that were not affected by ARTCA shall be 
deemed to be regulations issued under FFDCA section 408. Thus, FQPA 
converted existing food additive regulations issued by FDA under FFDCA 
section 409, for chemical substances that post-FQPA became pesticide 
chemicals, into FFDCA section

[[Page 37781]]

408 pesticide chemical tolerances or tolerance exemptions. This 
``grandfather'' provision of FFDCA section 408(j) assures that 
pesticide chemical residues conforming to regulations issued under the 
authority of FFDCA section 409 will not render food adulterated as a 
result of the jurisdictional shift from FDA to EPA.
    In 1998, ARTCA amended the definition of ``pesticide chemical'' in 
FFDCA section 201(q) so as to exclude certain antimicrobial pesticide 
residues from the authority of FFDCA section 408. Consistent with FFDCA 
section 408(j)(4), these residues now fall within the authority of 
FFDCA section 409. As a result, certain uses of food-contact surface 
sanitizing solutions identified in FDA's regulations at 21 CFR 178.1010 
remain subject to FFDCA section 409 regulations just as they did pre-
FQPA, while other uses are now subject to EPA's jurisdiction under 
FFDCA section 408.

B. Why are these Tolerance Exemptions not Subject to Tolerance 
Reassessment at this Time?

    Under FFDCA section 408(q), EPA is required to reassess all 
tolerance exemptions that were in effect on the day before the 
enactment of the FQPA. The tolerance exemptions for inert ingredients 
as well as those active ingredients not yet completed will be 
reassessed in accordance with EPA's schedule for tolerance reassessment 
published in the Federal Register of August 4, 1997 (62 FR 42019) (FRL-
5734-6).
    The tolerance exemptions in this proposed rule to be codified in 40 
CFR 180.940 already exist as valid FFDCA section 408 regulations. FDA 
promulgated the food additive regulations in 21 CFR 178.1010 under the 
authority of FFDCA section 409 prior to the enactment of FQPA. By 
operation of FFDCA section 408(j)(2), those portions of 21 CFR 178.1010 
that pertain to chemical substances that are pesticide chemicals post-
FQPA and remain as such post-ARTCA were converted to FFDCA section 408 
tolerance exemptions. EPA's duplication of these tolerance exemptions 
is not ``establishing, modifying, or revoking a tolerance'' under FFDCA 
section 408(b). EPA is, therefore, not required to conduct a full 
reassessment of these tolerance exemptions at this time.

C. Why is 40 CFR 180.940 being Created?

    The Agency is duplicating in 40 CFR 180.940 only those portions of 
the regulations in 21 CFR 178.1010 that pertain to pesticide chemicals. 
This duplication will have no effect on any of FDA's regulated FFDCA 
section 409 food additive regulations in 21 CFR 178.1010.
    In establishing food additive regulations for food-contact surface 
sanitizing solutions in 21 CFR 178.1010, FDA used a formulation-
specific approach. Consistent with its authority under FFDCA section 
409, FDA issued regulations prescribing the conditions under which 
food-contact surface sanitizing solutions might be safely used. FDA 
approved the use of each food-contact surface sanitizing solution 
formulation as a whole, rather than regulating each component chemical 
substance individually. In addition, FDA included a generic exemption 
for any chemical substance considered to be GRAS, and in some cases, 
issued letters not objecting to certain additional chemical substances 
in the formulations.
    By contrast, FFDCA section 408 authorizes EPA to issue regulations 
establishing tolerances or exemptions from the requirement of a 
tolerance. EPA's practice has been to issue these regulations on a 
chemical-specific basis, whereby each ingredient in the product is the 
subject of a separate tolerance or exemption regulation. Food-contact 
surface sanitizing solutions meet the requirements of FFDCA if each 
ingredient has an appropriate clearance under FFDCA, either a tolerance 
or an exemption from the requirement of a tolerance, and any conditions 
on the clearance are observed.
    Translating the regulatory decisions made by FDA into a comparable 
EPA scheme requires considerably greater work on EPA's part than merely 
copying those portions of the existing regulations in 21 CFR 178.1010 
that pertain to pesticide chemicals directly into 40 CFR 180.940. EPA 
must disaggregate the formulations in 21 CFR 178.1010 that pertain to 
pesticide chemicals into their component ingredients. EPA must also 
provide a mechanism to address those ingredients not identified by name 
in 21 CFR 178.1010 but that were, for example, permitted by prior 
sanction or approval, not objected to, or generally recognized as safe. 
This, in fact, places a higher initial demand on EPA resources than 
would be required to simply copy FDA's approach. However, EPA is 
convinced that the long-term administrative convenience of using a 
consistent regulatory scheme for all pesticide chemicals subject to 
FFDCA section 408 outweighs the initial burdens.
    FDA's formulation-specific approach is different from EPA's 
chemical-specific approach. Under EPA's approach, a tolerance exemption 
would be approved once for each particular pesticide chemical, and 
would not need to be repeated as new products containing that chemical 
substance enter the market. EPA's approval process is not complex, will 
allow for a wide variety of potential products, and fosters innovative 
formulation approaches. In addition, by listing in one place (40 CFR 
180.940) all chemical substances exempted from the requirement of a 
tolerance when used in food-contact surface sanitizing solutions, EPA's 
approach will increase the transparency of its regulatory process.
    This duplication will not allow any residues beyond those already 
permitted by 21 CFR 178.1010. EPA believes that the chemical-specific 
approach and FDA's formulation-specific approach are equivalent from a 
risk management perspective, inasmuch as each would result in the same 
levels of residues from these chemical substances.
    As part of the duplication, EPA changed the naming conventions 
(chemical nomenclature), as well as combining, as appropriate, chemical 
substances that appear in 21 CFR 178.1010 under two or more names under 
a single name. The Agency has attempted to identify each of the listed 
chemical substances using the Chemical Abstracts Service Registry 
Number (CAS No.). The CAS No. provides one of the most distinct and 
universally accepted means of identifying chemical substances. 
Generally, there will be only one CAS No. per listed chemical 
substance; however, it is possible that more than one CAS No. may be 
appropriate for some chemical substances. The lack of a CAS No. will 
not preclude EPA from including chemical substances in 40 CFR 180.940.
    The lower-concentration limits specified in 21 CFR 178.1010 are not 
included in 40 CFR 180.940 because of the differences between FDA's 
approach and EPA's approach. Although EPA establishes tolerance 
exemptions for use in food-contact surface sanitizing solutions under 
FFDCA, all pesticide products must also meet the criteria for 
registration under the Federal Insecticide, Fungicide, and Rodenticide 
Act (FIFRA) before being offered for sale. EPA relies on conditions 
imposed through the FIFRA registration process to address safety and 
for antimicrobial-formulated products efficacy. Accordingly, the lower 
limits on concentrations of pesticide chemicals, that appear in 21 CFR 
178.1010 will not appear in 40 CFR 180.940. Three types of food-contact 
surface sanitizing

[[Page 37782]]

solutions are described in 21 CFR 178.1010:
    [sbull] Those used on food-contact surfaces in public eating 
places.
    [sbull] Those used on dairy-processing equipment.
    [sbull] Those used on food-processing equipment and utensils.
    According to FDA, food-contact surface sanitizing solutions that 
are acceptable for use on food-contact surfaces in public eating places 
can also be used on dairy-processing equipment, and on food-processing 
equipment and utensils. Food-contact surface sanitizing solutions that 
are acceptable for use on dairy equipment can also be used on food-
processing equipment and utensils. EPA has separated the component 
ingredients by both chemical and concentration for these three types of 
food-contact surface sanitizing solutions, which will be included in 40 
CFR 180.940.

IV. Issuance and Withdrawal of Direct Final Rule

    In the Federal Register of December 3, 2002 (67 FR 71847) (FRL-
6824-2), the Agency published a direct final rule to establish 40 CFR 
180.940. Comments were received. In the December 3, 2002 Federal 
Register notice, EPA announced that it would withdraw the direct final 
rule if it received adverse comment, and proceed with proposed rule as 
provided by section 553 of the Administrative Procedure Act, 5 U.S.C. 
553. Because some of the comments were of a nature that would warrant a 
response if made on a proposed rule, they are adverse comments that 
require withdrawal of the direct final rule. Accordingly, EPA withdrew 
the direct final rule on March 24, 2003 (68 FR 14165) (FRL-7299-4).
    Several of the comments reflected some understandable confusion on 
the part of the commenters. While EPA's chemical-specific approach and 
FDA's formulation specific approach are essentially equivalent, the two 
approaches look and read differently. EPA disaggregated the 46 
formulations in 21 CFR 178.1010 into a list of chemicals. This list of 
chemicals was then subdivided into three separate lists based on use 
categories in 21 CFR 178.1010 (i.e., food-contact surfaces in public 
eating places, dairy processing equipment, and food-processing 
equipment and utensils). The 40 CFR 180.940(a) list contains only the 
chemicals specified in those formulations that were designated by FDA 
for use in public eating places. The 40 CFR 180.940(b) list contains 
only the chemicals specified in those formulations that were designated 
by FDA for use on dairy equipment. The 40 CFR 180.940(c) list contains 
all chemicals because all formulations in 21 CFR 178.1010 can be used 
on food-processing equipment and utensils.
    The maximum concentration level for each chemical was determined by 
evaluating the range derived from the lists in 40 CFR 180.940(a), (b), 
or (c). Where 21 CFR 178.1010 authorized several different sanitizing 
solutions each containing a particular chemical, but at different 
concentrations, EPA will use only the highest concentration as the 
upper limit, reflecting FDA's implicit determination that 
concentrations up to and including that limit do not compromise food 
safety. As an example, if three solutions authorized under 21 CFR 
178.1010 for use on dairy equipment contain chemical ``X'' at 
concentrations of 150, 200, and 240 parts per million (ppm), then 240 
ppm would be used as the upper limit in 40 CFR 180.940(b). If for 
chemical ``Y,'' concentrations of 150 and 200 ppm were specified, but 
in a third solution the concentration was not specified, then the upper 
limit for chemical ``Y '' in 40 CFR 180.940(c) would be specified as 
``none.'' This reflects FDA's implicit determination in regard to that 
third sanitizing solution that chemical ``Y '' could be used in any 
concentration without significant risk to food safety.
    In addition to the disaggregation, the Agency also in some cases 
used a different chemical nomenclature. CI (chemical index) names and 
CAS Nos. were used to the greatest extent possible. This is part of an 
Agency-wide effort to provide a common and consistent way to identify 
and represent chemical substances across the Agency. Thus, sodium 
hypochlorite became hypochlorous acid, sodium salt. In other instances 
(most commonly involving polymers or quaternary ammonium compounds), 
FDA approved in one solution a particular chemical that falls within a 
more inclusive chemical designation approved in another solution. If 
practicable in such instances, EPA has stated the tolerance exemption 
only in terms of the more inclusive chemical designation, implicitly 
exempting all chemical substances that fall within that designation. 
For example, n-alkyl (C12-C16) benzyl dimethyl 
ammonium chloride would be considered to be a subset of n-alkyl 
(C12-C18) benzyl dimethyl ammonium chloride. 
Another example, n-alkyl (C12-C18) benzyl 
dimethyl ammonium chloride (mw 351 to 380) would also be considered a 
subset of n-alkyl (C12-C18) benzyl dimethyl 
ammonium chloride. Both of the example chemicals would be accounted for 
under the nomenclature quaternary ammonium compounds alkyl 
(C12-C18) benzyl dimethyl, chlorides. For each 
comment questioning whether a particular chemical substance appeared in 
the direct final rule, the Agency was able to verify that the chemical 
for which the commenter expressed concern was included in 40 CFR 
180.940, albeit under a different designation.
    A commenter asked that instead of using the term ``oxychloro 
species,'' that sodium chlorite or chlorine dioxide should be used 
instead. The ``generated by'' language was considered to be confusing 
in a listing of chemical names. The Agency (as acknowledged by the 
commenter) used FDA's language, which is an approach which describes 
the process for generating the solution, not the components of the 
solution. If the end-products of the generation process were specific 
chemicals already included in the other solutions (and therefore 
already line-items), then the Agency used the disaggregated approach. 
However, for the oxychloro species generation methods described in 21 
CFR 178.1010(b)(34), the chlorite, chlorate, and/or chlorine dioxide is 
actually an equilibrium mixture. There are no separate line-item 
entries for these chemicals. In fact, the upper concentration limit is 
specified in terms of chlorine dioxide only, thus making it difficult 
to separate the chemicals into line items. The Agency determined 
therefore to maintain the original FDA language at this time. The 
Agency also considered that other generation methods for oxychloro 
species could be submitted as part of the non-designated prior approved 
chemical substances, which could impact the handling of this in the 
future.
    Several commenters asked if a specific combination of quaternary 
ammonium compounds expressly identified in 21 CFR 178.1010(b)(22) were 
included in 40 CFR 180.940. Each of the component chemicals identified 
in 21 CFR 178.1010(b)(22) are identified in 40 CFR 180.940 as subject 
to a tolerance exemption. The two components listed in 21 CFR 
178.1010(b)(22) are di-n-alkyl (C8-C10) 
dimethylammonium chloride (mw 332 to 361) and n-alkyl (C12-
C18) benzyl dimethyl ammonium chloride (mw 351 to 380). The 
first chemical is listed in 40 CFR 180.940 as ``Quaternary ammonium 
compounds, di-n-alkyl (C8-C10) dimethyl ammonium 
chloride average molecular weight (in amu) 332 to 361.'' 21 CFR 
178.1010(b)(22) and 21 CFR 178.1010(c)(17) together allow a maximum 
end-use concentration of 400

[[Page 37783]]

ppm of the two quaternary ammonium compounds in this solution, of which 
this particular chemical must comprise 60%. EPA's regulation exempts 
this chemical substance from the requirement of a tolerance in 
sanitizing solutions up to 240 ppm, which is 60% of the 400 ppm 
authorized in the FDA regulations. The second chemical is listed in 40 
CFR 180.940 as ``Quaternary ammonium compounds, alkyl (C12-
C18) benzyl dimethyl, chlorides.'' The end use concentration 
as specified in 21 CFR 178.1010(b)(22) and 21 CFR 178.1010(c)(17) for 
this chemical would be 40% of 400 ppm or 160 ppm. Because other 
solutions in 21 CFR 178.1010 included chemical substances within the 
description ``quaternary ammonium compounds, alkyl (C12-
C18) benzyl dimethyl, chlorides'' without molecular weight 
limitations and/or with higher concentration limits, the description of 
this chemical in 40 CFR 180.940 is more broad than that of 21 CFR 
178.1010(b)(22).
    Based on one comment, the Agency was made aware of a typographical 
error in the December 3, 2002 Federal Register notice which has been 
corrected in this notice of proposed rulemaking. In 40 CFR 180.940(a) 
the upper limit should be not 150 ppm, but 200 ppm for C12-
C16 benzyl dimethyl ammonium chloride (mw 351-380). With the 
change in upper limit to 200 ppm, C12-C16 benzyl 
dimethyl ammonium chloride (mw 351 to 380) can be appropriately held 
under the more inclusive quaternary ammonium compounds alkyl 
(C12-C18) benzyl dimethyl, chlorides.
    Another commenter requested that the Agency change the language 
describing the upper limit concentration for all quaternary ammonium 
compounds. The commenter has suggested the use of the phrase ``when 
ready to use, the end-use concentration is not expected to exceed `X' 
ppm of this active quaternary ammonium compound,'' instead of the 
phrasing used by the Agency ``when ready for use, concentration is not 
to exceed `X' ppm of active quaternary compound.'' The commenter cited 
the concern that state enforcement personnel would apply the limitation 
for a particular quaternary ammonium compound to a mixture. The Agency 
believes that the language it has used is clear and concise. The 
concentration limits specified in 40 CFR 180.940 apply only to the 
chemical substance described in the particular table entry. However, 
the 30-day comment period will allow the Agency to take further comment 
on this issue.
    A commenter asked that the Agency not distinguish between food-
contact surfaces in public eating places, dairy-processing equipment, 
and food processing equipment and utensils. These categories were 
originally created by the FDA and reflect different assumptions 
especially with regard to dietary exposure to sanitizer residues, and 
thus are an intrinsic part of FDA's risk assessments. Although EPA has 
the authority to reconsider FDA's risk assessments, EPA can do so only 
upon fully reassessing these tolerance exemptions in accordance with 
FFDCA section 408, as amended by FQPA. EPA is not reassessing these 
tolerance exemptions at this time, but instead merely duplicating FDA's 
previous clearances in a format consistent with EPA's authority under 
FFDCA section 408. EPA is required under FFDCA section 408(q)(1)(C) to 
complete tolerance reassessment for all pesticide chemicals by 2006, 
and will consider the commenter's suggestion during tolerance 
reassessment.
    Although not raised by commenters, EPA has made three additional 
changes from the December 3, 2003 Federal Register notice. D&C Blue 
No.1 (methylene blue) is now referenced as methylene blue. Similarly, 
FD&C Yellow No. 5 (tartrazine) is now referenced as FD&C Yellow No. 5. 
A CAS No. was added to one entry (quaternary ammonium compounds, alkyl 
(C12-C18) benzyl dimethyl, chlorides) in 40 CFR 
180.940(a).

V. Addition of Non-Designated, Prior Approved Chemical Substances

    21 CFR 178.1010 allows the use of GRAS chemical substances and 
chemical substances ``permitted by prior sanction or approval,'' that 
are not expressly identified. These chemical substances were subject to 
the sanitizer formulation approval under FDA's regulation before these 
uses became FFDCA section 408 tolerance exemptions under FFDCA section 
408(j)(2). Accordingly, many food-contact sanitizing solutions that 
presently are authorized for use under 21 CFR 178.1010 contain 
ingredients which are not identified in this direct final rule. As 
discussed in this unit, EPA is asking registrants to identify these 
other ingredients that they believe should be included in 40 CFR 
180.940. EPA intends to publish a revision to 40 CFR 180.940 adding 
these chemical substances. In the interim, to preserve the use of food-
contact surface sanitizing solutions that were cleared for use before 
FQPA's enactment and that contain chemical substances that are not 
specifically identified in 21 CFR 178.1010, EPA has decided to honor 
those approvals under 21 CFR 178.1010 until EPA has received and 
reviewed registrant's claims with respect to unspecified pesticide 
chemicals, as discussed in this unit.
    FDA's regulations (21 CFR 178.1010(b)) allowed the addition to 
food-contact surface sanitizing solutions of GRAS components, and 
components permitted by prior sanction or approval or subject to a 
letter of no objection. Much of this information should be in EPA's 
files. The Agency will access this information. However, EPA may not 
have ready access to all information on all chemicals in existing food-
contact surface sanitizing solution formulations which could meet these 
criteria. Submission of this information to EPA would also reduce the 
possibility of an existing food-contact surface sanitizing solution 
having a component that lacks a tolerance exemption under 40 CFR 
180.940. Therefore, registrants who believe that components of their 
food-contact surface sanitizing solutions are exempted under 21 CFR 
178.1010(b) should advise EPA in writing that these chemical substances 
(along with the CAS No.) should be included in 40 CFR 180.940. The 
submission of this information facilitates EPA's process for adding 
these chemical substances cleared under 21 CFR 178.1010(b), but not 
specifically listed by name, to 40 CFR 180.940. The EPA will also need 
any available information documenting the claim that the component is 
GRAS, prior sanctioned or approved, or subject to a letter of no 
objection.
    Claims and supporting documentation should be sent to the person 
listed under FOR FURTHER INFORMATION CONTACT. Claims are not comments 
on this direct final rule and should be identified on the subject line 
as ``Submission of Non-designated Prior Approved Chemical Substance.'' 
If you have any questions about the many types of information that 
could be submitted please consult the person listed under FOR FURTHER 
INFORMATION CONTACT. The Agency does not anticipate that registrants 
will be required to submit an excessive amount of information, and, in 
fact, believes that most registrants will be able to submit the 
necessary information with minimal effort. EPA will review and evaluate 
the information provided. Chemical substances identified in claims 
received not later than October 1, 2003, may be eligible for inclusion 
in 40 CFR 180.940 under FFDCA section 408(j)(2). EPA anticipates 
publishing a notice of proposed rulemaking identifying those chemical 
substances shortly after that date.

VI. Statutory and Executive Order Reviews

    This proposed rule would add a new Sec.  180.940 to 40 CFR part 
180, subpart D, which lists the pesticide chemicals that are exempt 
from the requirement of a tolerance when used in food-contact surface 
sanitizing solutions. The initial list duplicates pesticide chemicals 
in 40 CFR 180.940 that are active and inert ingredients listed in 21 
CFR 178.1010. Since this proposed rule does not impose any new 
requirements, it is not subject to review by the Office of Management 
and Budget (OMB) under Executive Order 12866, entitled Regulatory 
Planning and Review (58 FR 51735, October 4, 1993).
    Because this proposed rule has been exempted from review under 
Executive Order 12866 due to its lack of significance, this proposed 
rule is not subject to Executive Order 13211, Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use (66 FR 28355, May 22, 2001).
    This proposed rule does not impose any enforceable duty or contain 
any unfunded mandate as described under Title II of the Unfunded 
Mandates Reform Act of 1995 (UMRA) (Public Law 104-4).
    Nor does it require any special considerations under Executive 
Order 12898, entitled Federal Actions to Address Environmental Justice 
in Minority Populations and Low-Income Populations (59 FR 7629, 
February 16, 1994); or OMB review or any Agency action under Executive 
Order 13045, entitled Protection of Children from Environmental Health 
Risks and Safety Risks (62 FR 19885, April 23, 1997). This action does 
not involve any technical standards that would require Agency 
consideration of voluntary consensus standards pursuant to section 
12(d) of the National Technology Transfer and Advancement Act of 1995 
(NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note).
    In addition, the Agency has determined that this action will not 
have a substantial direct effect on States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government, as 
specified in Executive Order 13132, entitled Federalism (64 FR 43255, 
August 10, 1999). Executive Order 13132 requires EPA to develop an 
accountable process to ensure ``meaningful and timely input by State 
and local officials in the development of regulatory policies that have 
federalism implications.'' ``Policies that have federalism 
implications'' is defined in the Executive order to include regulations 
that have ``substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.'' This proposed rule directly regulates growers, food 
processors, food handlers and food retailers, not States. This action 
does not alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of section 408(n)(4) of the FFDCA. For these same reasons, the Agency 
has determined that this proposed rule does not have any ``tribal 
implications'' as described in Executive Order 13175, entitled 
Consultation and Coordination with Indian Tribal Governments (65 FR 
67249, November 6, 2000). Executive Order 13175, requires EPA to 
develop an accountable process to ensure ``meaningful and timely input 
by tribal officials in the development of regulatory policies that have 
tribal implications.'' ``Policies that have tribal implications'' is 
defined in the Executive order to include regulations that have 
``substantial direct effects on one or more Indian tribes, on the 
relationship between the Federal Government and the Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes.'' This proposed rule will not have 
substantial direct effects on tribal governments, on the relationship 
between the Federal Government and Indian tribes, or on the 
distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified in Executive Order 13175. 
Thus, Executive Order 13175 does not apply to this proposed rule.
    Under section 605(b) of the Regulatory Flexibility Act (RFA) (5 
U.S.C. 601 et seq.), the Agency hereby certifies that the creation of a 
new section 180.940 will not have significant negative economic impact 
on a substantial number of small entities. The rationale supporting 
this conclusion is as follows. This proposed rule does not impose any 
requirements, it establishes exemptions from the requirement for a 
tolerance. The Agency is, however, also commencing a process whereby 
EPA will require certain persons to identify chemical substances 
considered to be GRAS (which could include self-affirmed GRAS 
chemicals), or permitted by prior sanction or approval in existing food 
contact surface sanitizing solutions. The information available to the 
Agency indicates that fewer than 500 companies have approximately 1,300 
products that could fall under this category. EPA anticipates the 
economic burden on small entities to be minor, since the Agency is only 
asking for confirmation that the chemical substances considered to be 
GRAS or permitted by prior sanction or approval in existing food 
contact surface sanitizing solutions are in fact part of an existing 
formulation, and information as to why the chemical is considered to be 
GRAS, or a copy of an FDA letter not objecting to the use of a chemical 
substance. By contrast, this proposed rule will be beneficial to the 
regulated community by increasing the number of inert ingredients for 
use in antimicrobial formulations and by reducing the regulatory burden 
on persons seeking to market new combinations of ingredients for 
certain hard surface sanitizing solutions. Additionally, this proposed 
rule will provide a more transparent listing of pesticide chemicals 
used in food-contact surface sanitizing solutions to the public.
    According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et 
seq., an Agency may not conduct or sponsor, and a person is not 
required to respond to a collection of information that requires OMB 
approval under the PRA, unless it has been approved by OMB and displays 
a currently valid OMB control number. The OMB control numbers for EPA's 
regulations, after initial display in the preamble of the final rule 
and in addition to its display on any related collection instrument, 
are listed in 40 CFR part 9.
    This proposed rule does not impose any new information collection 
requirements that would require separate approval by OMB under the PRA. 
Under 5 CFR 1320.3(h), the request for information discussed in Unit V. 
is not subject to approval under the PRA, and the information 
collection activities related to the Agency's tolerance exemption 
process have already been approved by OMB under OMB control numbers 
2070-0024 (EPA ICR No. 597). The annual ``respondent'' (petitioner) 
burden for the pesticide tolerance petitions program is estimated to 
average 1,726 hours per petition. According to the PRA, ``burden'' 
means the total time, effort, or financial resources expended by 
persons to generate, maintain, retain, or disclose or provide 
information to or for a Federal agency. For this collection, it is the 
time reading the regulations, planning the necessary data collection 
activities, conducting tests, analyzing data, generating reports and 
completing other

[[Page 37785]]

required paperwork, and storing, filing, and maintaining the data. Send 
comments regarding this burden estimate or any other aspect of the 
collection activity, including suggestions for reducing the burden to: 
Director, Collection Strategies Division (2822), Environmental 
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001. Include the OMB control number 2070-0024 in any correspondence 
about this collection activity, but do not submit the requested 
information or forms to this address.

James Jones,
Director, Office of Pesticide Programs.
    Therefore, it is proposed that 40 CFR chapter I be amended as 
follows:

PART 180--[AMENDED]

    1. The authority citation for part 180 continues to read as 
follows:

    Authority: 21 U.S.C. 321(q), 346a and 371.
    2. A new Sec.  180.940 is added to subpart D of part 180 to read as 
follows.


Sec.  180.940  Food-contact surface sanitizing solutions; exemptions 
from the requirement of a tolerance.

    Residues of the following chemical substances are exempted from the 
requirement of a tolerance when used in accordance with good 
manufacturing practice as ingredients in an antimicrobial pesticide 
formulation, provided that the chemical substance is applied on a semi-
permanent or permanent food-contact surface (other than being applied 
on food packaging) with adequate draining before contact with food.
    (a) The following chemical substances when used as ingredients in 
an antimicrobial pesticide formulation may be applied to: Food-contact 
surfaces in public eating places, dairy-processing equipment, and food-
processing equipment and utensils.
