Registration Requirements for Antimicrobial Pesticide Products 
and Other Pesticide Regulatory Changes

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to establish procedures for the registration 
of antimicrobial products, as well as implement other provisions of the 
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended 
by the Food Quality Protection Act. This proposal is required by FIFRA.
    In addition to registration procedures for antimicrobial products, 
EPA also proposes to establish labeling standards for antimicrobial 
public health products, which will ensure that these products are 
appropriately labeled for the level of antimicrobial activity they 
demonstrate; to modify its notification process for antimicrobial 
products to conform to the statutorily prescribed process; and to 
exempt certain antimicrobial products from FIFRA regulation.
    EPA believes that the new procedures and provisions will streamline 
and improve the registration process, increase consistency and 
certainty for antimicrobial producers, reduce the timeframes for EPA 
decisions on antimicrobial registrations, increase public health 
protection by ensuring the continued efficacy of antimicrobial public 
health pesticides, and promote international harmonization efforts.
    EPA is also proposing to implement a number of general provisions 
of FIFRA that are not specific to antimicrobial pesticides. EPA 
proposes to interpret the applicability of the new FIFRA definition of 
``pesticide'' that excludes liquid chemical sterilants from FIFRA 
regulation and includes nitrogen stabilizers, and to describe 
requirements pertaining to use dilution labeling. These proposals are 
intended to implement new provisions of FIFRA, and to update current 
regulations and procedures.
    Finally, EPA is proposing technical, conforming and organizational 
changes to portions of its regulations on pesticide registration and 
labeling for clarity and understanding.

DATES: Comments, identified by the docket control number OPP-300890, 
must be received on or before November 16, 1999.

ADDRESSES: Comments may be submitted by regular mail, electronically,

III. Authority

A. The Federal Insecticide, Fungicide, and Rodenticide Act

    This proposal is issued under the authority of FIFRA sections 3 and 
25, 7 U.S.C. 136a and 136w. Under FIFRA, a pesticide product may not be 
distributed or sold in the United States unless it is registered with 
the EPA. Registration is a licensing process in which EPA evaluates 
each proposed product, its uses, and its labeling to determine whether 
it meets the standard for registration in FIFRA section 3(c)(5). That 
standard states that, for a registration to be approved, EPA must 
determine that the pesticide product, when used in accordance with its 
intended uses and with widespread and commonly recognized practice, 
will not cause unreasonable adverse effects on the environment. The 
registration standard is a risk/benefit standard, which must take into 
account the economic, social and environmental costs and benefits of 
use.

B. The Food Quality Protection Act

    On August 3, 1996, Congress enacted the Food Quality Protection Act 
(FQPA), modifying FIFRA and the Federal Food, Drug and Cosmetic Act 
(FFDCA). Most of its provisions were effective immediately, although 
some require implementing regulations. Units IV. and V. discuss the 
statutory provisions of FIFRA as amended by FQPA that this proposal 
would implement.

C. The Antimicrobial Regulation Technical Corrections Act

    On October 30, 1998, Congress enacted the Antimicrobial Regulation 
Technical Corrections Act (ARTCA), which modified the Federal Food, 
Drug, and Cosmetic Act (FFDCA) to effectively transfer authority over a 
number of pesticide residues to FDA. Regulatory authority over these 
residues had originally been transferred to EPA by FQPA. Unit XI. 
discusses the

[[Page 50674]]

consequences of this statute and how EPA and FDA jurisdiction over 
antimicrobial pesticide residues in food has been allocated by ARTCA.

IV. Antimicrobial Provisions Addressed in this Proposal

A. Overview

    The FQPA amendments to FIFRA focus attention on antimicrobial 
pesticides specifically, and the procedural framework under which the 
Agency reviews and approves applications for registration and amendment 
of antimicrobial pesticides. This unit discusses the new statutory 
provisions for antimicrobial products and how this proposal satisfies 
each statutory requirement.
    1. Under FIFRA section 3(h)(1), EPA must evaluate its registration 
process to identify improvements and reforms that would reduce 
historical review times for antimicrobial applications.
    2. FIFRA section 3(h)(2) defines the goals for review that process 
improvements should be designed to achieve, expressed as review period 
reduction goals for various types of applications.
    3. Under FIFRA section 3(h)(3)(A), EPA must propose regulations 
that address a number of application process elements, with the goal of 
implementing specified process management improvements and meeting 
section 3(h)(2) goals. EPA is today proposing these regulations. Unit 
VIII. discusses each of following statutorily mandated elements, and 
briefly describes how today's proposal addresses those requirements:
    a. Defining the classes of antimicrobial use patterns.
    b. Defining types of application review.
    c. Conforming reviews to risks and benefits.
    d. Ensuring efficacy.
    e. Meeting review time goals.
    4. Under FIFRA section 3(h)(3)(B), EPA must in its final rule 
consider specified types of application and process improvements that 
would contribute to meeting the review time goals or otherwise simplify 
the application process, including:
    a. Certification mechanisms for applications.
    b. Certification of laboratories.
    c. Expanded use of notification and non-notification procedures.
    d. Clarification of completeness criteria for applications.
    e. Revised procedures for application review.
    f. Allocation of resources.
    In order to consider these topics for inclusion in the final rule, 
EPA must offer proposals or options for notice and comment today that 
could be incorporated into a final rule. EPA is today proposing 
regulations addressing expanded use of notification procedures (see 
Unit XVI.) and completeness criteria (See Unit VIII.F.). EPA has 
considered certification mechanisms for applicants, and, as discussed 
in Unit IV.G., may establish such a mechanism administratively. EPA has 
also considered the possibility of laboratory certification programs, 
but is not making a specific proposal at this time.
    Under FIFRA section 3(h)(3)(B), a final regulation must be 
promulgated no later than 240 days after the end of the comment period 
for those portions of this proposal required by FIFRA section 3(h).

B. Defining Classes of Antimicrobial Use Patterns

    FIFRA section 3(h)(3)(A)(ii)(I) requires that EPA ``define the 
various classes of antimicrobial use patterns.'' EPA has developed a 
comprehensive list of antimicrobial use patterns in conjunction with 
its upcoming part 158 proposal on antimicrobial data requirements. That 
proposal would establish a set of data requirements that apply solely 
to antimicrobial pesticides. EPA has developed an appendix of all 
current antimicrobial use patterns, divided into 12 use categories 
having common exposures or other similarities. The proposal meshes with 
the statutory mandate to identify classes of antimicrobial use patterns 
by defining, for each use category, the data requirements that apply. 
Unit VIII.D. includes a list of the use categories. A copy of the full 
draft Use Appendix is in the docket for this proposal. EPA intends its 
proposal of part 158 data requirements to satisfy the statutory 
requirement to define classes of antimicrobial use patterns.

C. Defining Types of Application Reviews

    FIFRA section 3(h)(3)(A)(ii)(II) requires that EPA ``differentiate 
the types of review undertaken for antimicrobial pesticides.'' Since 
the primary purpose of differentiating types of review is to ensure 
that review time goals are met, EPA views the statutory requirement as 
equivalent to defining the types of applications associated with the 
review periods in section 3(h)(2). Proposed Sec. 152.445 addresses the 
various application types, and describes the general criteria EPA uses 
to characterize an application. EPA intends that this section will 
satisfy the statutory requirement to differentiate types of reviews, 
and also in part will satisfy the requirement for setting out differing 
levels of data requirements for various classes of products under FIFRA 
section 3(h)(3)(A)(ii)(I).

D. Conforming Degree of Review to Risks and Benefits

    FIFRA section 3(h)(3)(A)(ii)(III) requires that EPA ``conform the 
degree and type of review to the risks and benefits presented by 
antimicrobial pesticides and the function of review under this Act, 
considering the use patterns of the product, toxicity, expected 
exposure and product type.''
    The function of review under FIFRA for any pesticide product, not 
just an antimicrobial pesticide, is grounded in the registration 
standards of FIFRA section 3(c)(5). As such, EPA review must:
    1. Assess the risks and benefits of the pesticide and its use, 
relevant to the determination of unreasonable adverse effects. In the 
case of a public health antimicrobial pesticide, a determination that 
the product is efficacious when used as directed is central to a 
benefits assessment.
    2. Determine the adequacy of the pesticide labeling in directing 
the pesticide user as to intended and safe use of the pesticide, 
thereby minimizing potential adverse effects to the user and the 
environment.
    EPA believes that its proposed part 158 regulation defining use 
categories and data requirements clearly acknowledges that different 
use patterns have different exposure patterns and risks. The data 
requirements for each use category are commensurate with the potential 
exposures and risks associated with that use pattern, and in some cases 
are tiered so that higher exposures or higher risks require a second 
level of data. The amount and types of data required in and of 
themselves dictate a review process that is more detailed, requiring a 
more complex assessment for these potentially higher exposures or 
higher toxicity. Therefore, in issuing part 158, EPA intends that the 
mandate to conform the degree and type of review to risks and benefits 
of use will be satisfied.

E. Ensuring Efficacy

    FIFRA section 3(c)(5) has required since 1972 that the composition 
of a pesticide be such as to warrant the claims made for it, i.e., that 
a product work as claimed. Moreover, the registrant must ensure that 
the pesticide product continues to meet that efficacy standard as long 
as the product is registered. What has changed over time is the manner 
in which EPA is assured of product efficacy. Until 1980, EPA

[[Page 50675]]

reviewed efficacy data for every pesticide product prior to 
registration, and thus could assure that, at least at the time of 
registration, each product would perform as intended. In 1980, EPA 
determined that, for pesticides of economic or aesthetic significance, 
the marketplace can be relied upon to weed out inefficacious products. 
EPA reasoned that because users can determine for themselves whether a 
product works, and are motivated by economic reasons to ensure that 
they are using the most efficacious products, less efficacious products 
would not survive in a highly competitive marketplace. Accordingly, EPA 
no longer routinely reviews efficacy data prior to registration for 
most insecticides, fungicides, herbicides, and non-public health 
antimicrobial pesticides. Registrants must maintain data demonstrating 
efficacy in their files, and submit it to the Agency upon request.
    EPA recognized, however, that it could not reduce its efficacy 
oversight of public health products and still be assured of product 
efficacy. The failure of public health products to work as intended 
could have consequences far beyond those of mere economic or aesthetic 
significance. Consumers and public health officials must have assurance 
that a product will work against pests that pose public health threats. 
Many public health products are antimicrobial pesticides registered to 
control bacteria, viruses, protozoa, and other microorganisms 
pathogenic to man (others are insecticides and rodenticides controlling 
pests that are vectors of disease in man). Unlike insects or weeds, 
microbial pests cannot be seen, and users cannot determine by 
observation whether the product actually performs as claimed. 
Therefore, EPA cannot rely upon the users or marketplace forces to 
ensure product efficacy. Accordingly, EPA has continued to review 
efficacy data for public health products prior to registration.
    Subdivision G of the Pesticide Assessment Guidelines describes the 
efficacy tests required, and the Labeling Guidelines for Pesticide Use 
Directions - Antimicrobial Products (Subdivision H) contain the 
performance standards that EPA uses to ensure that antimicrobial 
products achieve an acceptable level of efficacy for the claims made. 
The Pesticide Assessment Guidelines are available from the National 
Technical Information Service, 5285 Port Royal Road, Springfield, VA 
22161.
    FIFRA section 3(h)(3)(A)(ii)(IV) requires EPA to ``ensure that the 
registration process is sufficient to maintain antimicrobial pesticide 
efficacy and that antimicrobial pesticide products continue to meet 
product performance standards and effectiveness levels for each type of 
label claim made.'' At first glance, this language may appear merely to 
reinforce the existing efficacy standard of FIFRA section 3(c)(5) that, 
to be registered, a product must be efficacious. On closer reading, 
however, it is clear that the language carries a broader mandate making 
explicit the role of the registration process in ensuring continued 
efficacy after registration.
    EPA has relied on post-registration mechanisms, including 
enforcement monitoring, good laboratory practice monitoring and data 
audits, testing by EPA and States as co-regulators, registrant 
reporting under FIFRA section 6(a)(2), and user complaints to target 
inefficacious products in the marketplace. In recent years, enforcement 
actions have found a number of incidents of product failure which have 
called into question the ability or willingness of producers to ensure 
and maintain the efficacy of their products after registration. As a 
result, EPA has since 1990 undertaken a systematic testing program for 
antimicrobial pesticides. In cooperation with FDA, EPA has tested 
sterilant products and has brought a number of enforcement and 
regulatory actions against products found to be inefficacious. EPA is 
now testing tuberculocides and hospital disinfectants.
    After a product has been identified as failing in efficacy, EPA may 
use enforcement measures (such as Stop Sale, Use and Removal Orders) to 
correct problems. EPA may also use remedies such as cancellation of 
registration under FIFRA section 6 to remove inefficacious products 
from the marketplace. EPA has found that post-registration reporting, 
monitoring, testing and cancellation processes can be cumbersome and 
time-consuming. In some cases, products that EPA has found to be 
inefficacious have taken years for resolution through the hearing and 
appeals processes available to registrants.
    EPA agrees wholeheartedly that measures to strengthen the Agency's 
oversight of antimicrobial efficacy as part of registration are 
desirable. Today's proposal contains two specific provisions to improve 
and strengthen EPA's regulatory oversight of the efficacy of public 
health antimicrobial pesticides:
    1. EPA proposes to incorporate into its regulations, as subpart W 
of part 156, the efficacy performance standards for public health 
products that are now contained only in its Labeling Guidelines. Unit 
XII. further discusses efficacy performance standards for public health 
antimicrobial pesticides.
    2. EPA proposes to limit the duration of registrations bearing 
public health claims to 5 years. In order to extend the registration 
for an additional 5 years, each registrant would have to confirm by 
analysis that the product composition was the same as that in Agency 
files previously demonstrated to be efficacious, and that the product 
continued to meet efficacy standards specified in subpart W for each 
public health claim. Unit IX. discusses the 5-year duration provision 
in greater detail.
    EPA believes that these two regulatory provisions will fulfill the 
statutory requirement that EPA ensure continued product efficacy 
through the registration process.

F. Implementing Deadlines for Process Management

    FIFRA section 3(h)(3)(A)(ii)(V) requires that EPA ``implement 
effective and reliable deadlines for process management.'' EPA believes 
that the ``deadlines'' referred to are those contained in FIFRA section 
3(h)(1), which requires EPA to identify and evaluate reforms to the 
antimicrobial registration process; FIFRA section 3(h)(2), which 
establishes goals for reduction of review periods for antimicrobial 
applications for registration; and FIFRA section 3(h)(3)(D), which 
establishes default review periods that apply if EPA fails to issue its 
final antimicrobial rule by the statutorily required deadline. As 
discussed more fully in Unit VIII.H., EPA is today proposing in 
Sec. 152.457 to adopt the ``goal'' review periods rather than the 
``default'' review periods.

G. Certification Process for Regulatory Actions

    FIFRA section 3(h)(3)(B)(iii)(I) requires that, in issuing final 
regulations, EPA must ``consider the establishment of a certification 
process for regulatory actions involving risks that can be responsibly 
managed, consistent with the degree of risk, in the most cost-efficient 
manner.''
    Certification statements are currently permitted by 
Sec. 152.44(b)(2) for various types of amendments to registration when 
directed by EPA. Typically, EPA uses certification to accomplish 
specific changes to registration (frequently labeling changes). EPA has 
included in this proposal a broader provision that would allow the 
Agency to implement self-certification programs as needed in

[[Page 50676]]

the future administratively. Unit VIII.A. discusses further this 
provision.
    With respect to data certification, EPA has considered two self-
certification programs in the recent past, and has implemented one of 
these. PR Notice 98-1, Self-Certification of Product Chemistry Data, 
was issued on January 12, 1998. In that notice, EPA describes the types 
of product chemistry information (product characteristics) that can be 
supplied to the Agency together with a self-certification that the data 
were conducted according to EPA Guidelines. Under this program, EPA 
would generally review only the summarized results of testing at the 
time of application, but could review full study reports if EPA 
determines that a complete evaluation of the study is warranted. Review 
of the summary results of testing rather than of the complete study 
report would decrease the time needed for all applications for 
registration of new products and reregistration of existing products.
    EPA also considered a similar self-certification procedure for 
acute toxicity data, and intends in the future to implement such a 
program for antimicrobial products only. EPA originally considered an 
acute toxicity data self-certification program because a backlog of 
applications requiring acute toxicity data review extended review 
periods while applications waited in queue. The certification mechanism 
considered would have been available only with respect to a study 
indicating that the product should be assigned to Toxicity Category III 
or IV. The certification procedure was viewed as a means of reducing 
the resources needed for review, and thus making more decisions with 
the same level of resources. At the same time, EPA recognized that the 
certification procedure could also reduce to some extent the Agency's 
confidence in hazard and precautionary statements on labeling. Since 
EPA issued its notice for comment, however, the Agency has achieved a 
significant reduction in the backlog and consequently in the review 
times for applications in the queue. The Agency decided therefore not 
to pursue a certification approach for acute toxicity studies at this 
time.
    Although EPA has decided not to adopt such an approach for 
pesticides in general, the Agency has decided to consider a pilot 
program that allows applicants for registration of antimicrobial 
product to certify the results of an acute toxicity study when the test 
data would indicate the product is in Toxicity Category I (the highest 
toxicity category). Because such a product would be subject to the most 
stringent labeling requiements, applicants would have no incentive to 
certify that a product of lower toxicity was in Toxicity Category I. 
Moreover, EPA's review of such data would add little value and would 
use limited resources. EPA invites comment on this proposed approach to 
certification of acute toxicity data, which would be implemented by a 
notice to registrants if EPA decides to adopt it.

H. Certification of Laboratories

    FIFRA section 3(h)(3)(B)(iii)(II) requires EPA to ``consider the 
establishment of a certification process by approved laboratories as an 
adjunct to the review process.'' EPA currently has underway a broad 
program across the Agency evaluating the feasibility of laboratory 
accreditation mechanisms for a variety of program and regulatory needs. 
The Office of Pesticide Programs has also been actively working with 
outside groups, such as the Chemical Specialties Manufacturers' 
Association to further their efforts to develop laboratory 
accreditation programs for antimicrobial products. EPA has considered 
whether a program could be instituted at this time for antimicrobial 
products, and believes that these efforts need further evaluation and 
development before being integrated into the Agency's regulatory 
programs. EPA intends to continue its cooperative work, and to fold its 
efforts into the larger Agency process. Thus, EPA is not today 
proposing a specific laboratory accreditation process as part of this 
proposed rule.

I. Notification Processes

    FIFRA section 3(h)(3)(B)(iii)(III)(aa) requires that, in issuing 
final regulations, EPA must use ``expanded use of notification and non-
notification procedures.'' This requirement dovetails neatly with the 
statutorily expanded scope of notifications under FIFRA section 
3(c)(9). EPA is today proposing to include in new Sec. 152.446 the new 
procedures to expand the use of notification as a mechanism for the 
label modification as directed by section 3(c)(9).

J. Revised Procedures for Application Review

    FIFRA section 3(h)(3)(B)(iii)(III)(bb) requires that, in issuing 
final regulations, EPA must use ``revised procedures for application 
review.'' As outlined in Unit VII, EPA's current regulations for 
registration of pesticide products, including antimicrobial pesticides, 
are generally limited to describing the applicant's and Agency's 
responsibilities and interactions. The summary description given in 
that unit is similar for all pesticides. EPA intends to issue or revise 
its current non-regulatory guidance documents that address the 
application process in greater detail. To the extent that EPA develops 
different procedures for antimicrobial products than for other 
products, EPA will make those procedures available via direct notice to 
affected registrants, and will make them widely available by all 
feasible means, including electronic accessibility.
    The Agency has already implemented a number of administrative 
reforms to improve the process, including revised procedures for 
review. Since FQPA was enacted, the Agency has established a separate 
Division solely responsible for antimicrobial products. The new 
Antimicrobials Division is charged with all aspects of antimicrobial 
regulation, and includes a full complement of scientific personnel in 
biology, microbiology, chemistry, toxicology, and other scientific 
disciplines, as well as an ombudsman to deal directly with registrant 
issues and concerns.
    The new Division has focussed initially on meeting the review 
period goals established by the statute for all new applications. To 
assist this effort, a dedicated Expedited Review Team has been formed 
for the purpose of processing notifications and screening and 
processing applications that are ``fast-track'' or with review periods 
of 90 days or less. By identifying and handling the less complex 
actions, this team allows the Division to channel its scientific and 
management resources into review of applications that are of higher 
priority or that require in-depth review. The Division has added more 
Product Managers, so that each Product Manager has a smaller and more 
focussed product universe.
    The Division has also targeted increased outreach, communication 
and information exchange as a high priority. Training materials, 
information sheets, operating procedures and science reviews have been 
developed or reevaluated for streamlining opportunities.
    Additional administrative accomplishments and plans are detailed in 
the Agency's first progress report to Congress, Streamlining 
Registration of Antimicrobial Pesticides, July 1997. EPA will issue 
this report annually as required by section 3(h)(4). Each report will 
identify further progress in management and administrative reforms.

K. Allocation of Resources

    FIFRA section 3(h)(3)(B)(iii)(III)(cc) requires that, in issuing 
final

[[Page 50677]]

regulations, EPA must address ``allocation of appropriate resources to 
ensure streamlined management of antimicrobial pesticide 
registrations.'' The allocation of resources is not a reform that can 
be accomplished by Agency regulations, and EPA is not proposing any 
regulations for doing so. Budget and resource allocations are guided by 
Executive branch and Congressional priorities and are determined year 
by year based on overall needs of the Agency and the pesticide program.

L. Completeness of Applications

    FIFRA section 3(h)(3)(B)(iii)(IV) requires that, in issuing final 
regulations, EPA must ``clarify criteria for determination of the 
completeness of an application.'' EPA is today proposing in Sec. 152.3 
a definition of a ``complete application'' for all registration 
applications. In addition, specific to antimicrobial products, and 
directly responsive to the requirement of FIFRA section 3(h)(3)(B), EPA 
is proposing in Sec. 152.450 to describe in detail the contents of an 
application, and the criteria that will be used to judge the 
completeness of the application as a whole, and of its individual 
components. EPA's proposals are discussed further in Unit VIII.F.

V. Other Statutory Provisions Addressed in this Proposal

A. Changes to the Definition of ``Pesticide''

    FQPA modified FIFRA section 2(u) to exclude certain liquid chemical 
sterilant products from the definition of ``pesticide,'' and to include 
certain nitrogen stabilizer products. This provision was effective on 
August 3, 1996. In recognition of this provision, EPA is proposing to 
add a new Sec. 152.6 entitled ``Substances excluded from regulation by 
FIFRA.'' EPA has issued a notice to registrants, entitled ``Liquid 
Chemical Sterilant Products'' (PR Notice 98-2; January 15, 1998), 
explaining how it will treat liquid chemical sterilants affected by 
section 2(u). Units XIV. and XV. discuss chemical sterilants and 
nitrogen stabilizers.

B. Notification Procedures

    FIFRA section 3(c)(9)(C) now authorizes registrants of 
antimicrobial products to make certain defined labeling modifications 
by notification to the Agency instead of amendment, and establishes a 
procedure for notifications and Agency decisions. This provision was 
effective on August 3, 1996, and the new procedures are exclusive to 
antimicrobial products. Today's proposal codifies these new 
notification procedures. The substance of the expanded notifications 
permitted by FIFRA section 3(c)(9) is issued in notices to registrants 
(PR Notices), and not in today's proposal. Unit XVI. discusses 
antimicrobial notifications.

C. Use Dilution Labeling

    FIFRA section 3(c)(9)(D) authorizes registrants to include on their 
labeling precautionary statements about the product as diluted for use 
(use dilution labeling). This provision was effective on August 3, 
1996. EPA proposes to reformat its human hazard labeling requirements 
in Sec. 156.10(h) and to incorporate use dilution requirements in 
appropriate sections. Unit XIII.A. discusses use dilution labeling.

VI. What is an Antimicrobial Pesticide?

    EPA proposes in Sec. 152.3 a definition and interpretation of 
antimicrobial pesticide. The proposed definition is paraphrased from 
that in section 2(mm) of FIFRA, and interprets the undefined elements. 
Because FIFRA section 3(h) directs EPA to develop and implement special 
procedures in its regulatory program for antimicrobial pesticides, it 
is important that there be a well-defined and commonly understood 
universe of products to which the statutory provisions apply. The 
practical consequences of being included or excluded as an 
``antimicrobial pesticide'' are significant for both pesticide 
producers and the Agency. FIFRA section 2(mm) defines the term 
``antimicrobial pesticide,'' carefully delineating its boundaries to 
mesh with the practical implementation of section 3(h) requirements. 
This unit discusses the definition in detail.

A. General Definition

    Under FIFRA section 2(mm)(1)(A), an antimicrobial pesticide is 
defined as

    :(A) [A pesticide that] is intended to:
    (i) disinfect, sanitize, reduce or mitigate growth or 
development of microbiological organisms; or
    (ii) protect inanimate objects, industrial processes or systems, 
surfaces, water, or other chemical substances from contamination, 
fouling or deterioration caused by bacteria, viruses, fungi, 
protozoa, algae, or slime;

    With respect to the scope of pests covered by the definition, 
paragraph (i) focusses on the intended pesticidal function (disinfect, 
sanitize, etc.) against non-specific ``microbiological organisms,'' 
while paragraph (ii) focusses on non-specific ``protection'' provided 
by the pesticide against specified microorganisms (bacteria, viruses, 
etc). As a practical matter, EPA believes that the term 
``microbiological organisms'' in paragraph (i) should be considered to 
include each of the specific types of microorganisms in paragraph 
(ii)--bacteria, viruses, fungi, protozoa, and algae. Therefore, EPA 
will consider any product intended for use against the microorganisms 
specified in paragraph (ii) to be an antimicrobial pesticide (subject 
to the exclusions discussed in Unit VI.B. and C.)
    Having identified the universe of substances that, based upon the 
intended pesticidal purpose, are antimicrobial pesticides, the 
definition goes on in paragraphs (1)(B) and (2) to exclude certain 
pesticides from the definition of antimicrobial pesticide. These 
exclusions may be characterized as use-based, that is, a pesticide is 
excluded because of how or where it is used, and not because of the 
pests or purpose of use.

B. Food Use Exclusion

    FIFRA section 2(mm)(1)(B) excludes from ``antimicrobial pesticide'' 
those pesticides whose intended antimicrobial use is such that residues 
in food requiring regulation under section 408 or 409 of the FFDCA 
might result.

    (B) [A pesticide that] in the intended use is exempt from, or 
otherwise not subject to, a tolerance under section 408 of the 
Federal Food, Drug, and Cosmetic Act (21 U.S.C. 346a and 348) or a 
food additive regulation under section 409 of such Act.

    In creating this exclusion, Congress recognized that applications 
for registration of food uses that require clearance under FFDCA 
require extensive data and relatively complex risk assessments that 
take longer to review. Moreover, obtaining an FFDCA clearance is a 
formal regulatory procedure. As discussed in Unit VIII.H., FIFRA 
section 3(h) establishes goals for completion of Agency review of an 
application for registration. In EPA's view, Congress recognized the 
difficulty of requiring the review timeframes for registration to 
encompass the complexities of FFDCA clearance as well. Accordingly, EPA 
believes that Congress intended the statutory definition to allow 
exclusion of any antimicrobial pesticide that would require the 
extensive clearance process of the FFDCA.
    The statutory language uses the phrases ``exempt from'' and ``not 
subject to'' a clearance under FFDCA. The phrase ``exempt from'' is 
clear and has meaning under FFDCA: an exemption from the requirement of 
a tolerance is a formal regulatory determination made by EPA. 
Exemptions from the requirement of a tolerance are found in 40 CFR part 
180.

[[Page 50678]]

    The phrase ``not subject to'' is not a formal determination under 
FFDCA. Any product that bears a food use is ``subject to'' a tolerance, 
that is, a tolerance or other clearance is required, whether that 
tolerance has been established or not. EPA believes the statutory 
language may be unintentionally broad in not differentiating between 
food uses subject to an ``existing'' tolerance and those subject to a 
``new'' tolerance. Products and uses subject to an existing tolerance 
do not require extensive review; only products subject to a new 
tolerance require such review. As written, the definition excludes both 
types of antimicrobial pesticides, although the apparent intent is to 
exclude only those requiring the lengthy and complicated tolerance-
setting review associated with a new clearance.
    In its discretion, EPA proposes to narrow the food use exclusion to 
conform to what it believes is the probable intent of Congress. EPA 
proposes to exclude from the definition of ``antimicrobial pesticide'' 
only products bearing one or more uses for which a new clearance is 
needed, or an amendment of an existing clearance. EPA proposes to 
include in the definition of ``antimicrobial pesticide'' (to exclude 
from the exclusion) product/uses ``subject to'' an existing tolerance. 
EPA believes that this narrower policy choice, while not required, more 
closely reflects the intent to include in the definition of 
``antimicrobial pesticide'' products requiring little or no review and 
to exclude only products needing the extensive and time-consuming 
evaluation associated with the establishment of a new or amended 
clearance.
    An antimicrobial pesticide, then, is a product bearing only non-
food uses, only food uses covered by an existing clearance under FFDCA, 
or some combination of these two.
    Given the food use exclusion, it is clear that the status of an 
antimicrobial product as an ``antimicrobial pesticide'' within the 
meaning of FIFRA section 3(h) is not necessarily a permanent 
designation, but may shift according to its intended use. A product 
could be included or excluded from the definition if the intended use 
changes. The status of a pesticide as an ``antimicrobial pesticide'' 
becomes pertinent and can only be determined at the time of submission 
of an application for Agency decision. At that time, EPA must determine 
whether the pesticide application is for an antimicrobial pesticide 
within the meaning of the statutory definition.
    The prime example of this use-dependent phenomenon is an 
application seeking the first food use of an antimicrobial pesticide. A 
product that heretofore has been an ``antimicrobial pesticide'' because 
it bears only non-food uses or tolerance-covered food uses is no longer 
an ``antimicrobial pesticide'' for purposes of EPA review and decision 
on that first food use action. Provisions of FIFRA applying only to 
``antimicrobial pesticides,'' notably the review periods, would not be 
triggered for that action. Once the food use issue is resolved or a 
tolerance issued, such that the food use is covered by an existing 
tolerance, the product may revert to ``antimicrobial pesticide'' status 
for a subsequent action.

C. Other Specific Exclusions

    FIFRA section 2(mm)(2) contains further specific exclusions to the 
definition. These are intended to clarify that certain types of 
products that might be considered ``antimicrobial pesticides'' because 
they have a pesticidal effect on the defined types of microorganisms 
are nonetheless not to be regulated as antimicrobial pesticides for 
purposes of FIFRA section 3(h). It should be noted that certain types 
of antimicrobial products are already excluded from regulation under 
FIFRA, and therefore from any coverage under this proposed rule. 
Products used against microorganisms in or on man or other living 
animals are not pesticides because such microorganisms are not 
``pests'' under FIFRA section 2(t). Products intended for use against 
microorganisms in or on man and animals are regulated solely by FDA. 
This is not a change from longstanding FIFRA provisions.
    1. Certain wood preservatives and antifouling paints. Any product 
that is a wood preservative or antifoulant paint, and that also bears 
any claim for a pesticidal activity other than or in addition to those 
specified in section 2(mm)(1) is not an antimicrobial pesticide. The 
pesticidal activities that generally define an ``antimicrobial 
pesticide'' include activity against any microbiological organisms, and 
``protection'' against the destructive effects of bacteria, viruses, 
fungi, protozoa, algae, and slime.
    Both wood preservatives and antifoulant paints (which are used to 
protect surfaces in contact with water such as boats) may function to 
protect against bacteria, fungi, etc., and thus, without a specific 
exclusion, would be deemed to be antimicrobial pesticides. However, 
since most wood preservatives also protect against insect damage, and 
most antifouling paints also protect against barnacles, the majority of 
these products are not likely to be ``antimicrobial pesticides.'' As 
discussed in Unit VIII.H., however, some wood preservative products may 
be eligible for the review deadlines that apply to antimicrobial 
pesticides.
    2. Agricultural fungicides. The definition of antimicrobial 
pesticide in FIFRA section 2(mm) excludes ``agricultural fungicides.'' 
Traditionally, the term ``fungus'' in an agricultural context has been 
used to mean microorganisms that are pathogenic to plants. Fungi (and 
other microorganisms) that are pathogenic to man and animals have 
historically been treated separately because of their public health 
implications. However, FIFRA section 2(k) defines ``fungus'' broadly to 
include a variety of other microorganisms, including rust, smut, 
mildew, mold, yeast, and bacteria, without specific reference to 
whether the microorganisms are pathogenic to plants or to man and 
animals.
    EPA intends the term ``agricultural fungicide'' to apply to all 
products applied in or on growing crops or to soil (i.e., pre-harvest 
application), regardless of the type of pest fungus. Although this 
would exclude as ``antimicrobial pesticides'' products applied pre-
harvest against microorganisms that might be pathogenic to man and 
animals, EPA is not aware that any pesticides are currently registered 
against human and animal pathogens on growing crops. EPA would regulate 
such products if the need arose, but they would not be covered by 
subpart W.
    Under this interpretation, a product intended for post-harvest 
application against fungi (including bacteria) would not be an 
``agricultural fungicide.'' Significantly, however, such a product 
would not necessarily be an ``antimicrobial pesticide'' either, since 
the food use exclusion also comes into play. Post-harvest application 
of fungicides or antimicrobial products to food or feed crops would run 
afoul of the food use exclusion if a new or amended tolerance were 
needed to cover pesticide residues. All post-harvest use antimicrobial 
products would be subject to subpart W generally; however, not all 
would be ``antimicrobial pesticides'' eligible for the review periods 
in Sec. 152.457.
    3. Aquatic herbicides. Further, the definition of antimicrobial 
pesticide excludes aquatic herbicide products. EPA interprets the term 
aquatic herbicide to mean pesticides used in or near environmental 
bodies of water, such as lakes, streams, or ponds, for the control of 
algae or weeds. In contrast, a

[[Page 50679]]

product intended for control of algae in industrial systems or 
processes or swimming pools would be considered an antimicrobial 
product.

D. Products Included

    Finally, section 2(mm)(3) lists a number of products that are 
deemed to be antimicrobial pesticides, to ensure that they are not 
inadvertently excluded by application of the various exclusions 
elsewhere. These include chemical sterilants other than those excluded 
under FIFRA section 2(u), other disinfectant products, industrial 
microbiocides, and preservatives other than wood preservatives.

VII. Current Registration Procedures for Pesticides

    Under FIFRA prior to FQPA, antimicrobial pesticides were not 
singled out as a class of pesticide products requiring special 
procedural attention. Antimicrobial pesticides were registered using 
the same procedures and policies as other pesticide products. 
Antifoulants, wood preservatives, and traditional antimicrobial 
pesticides were in separate organizational units within EPA.

A. Overview of Procedures

    A brief discussion of the registration procedures which have 
applied to all products follows. Even though products that are 
``antimicrobial pesticides'' will now be subject to a more carefully 
drawn and rigorously applied regulatory program, the basic procedures 
for registration will continue to apply.
    1. A person seeking to register any pesticide product must submit 
an application for registration. That application contains information 
on the pesticide, copies of the proposed labeling of the product, and 
data of various types supporting the registration (such as chemistry, 
toxicology, environmental fate, ecological effects). If a food use is 
involved, data supporting a clearance for residues in food are also 
required, and if the product is of public health significance, efficacy 
data must be submitted. Current regulations governing submission of 
applications are found in 40 CFR part 152. Data requirements are 
described in 40 CFR part 158, and labeling requirements in 40 CFR part 
156. The tolerance-setting process is contained in 40 CFR part 180.
    2. At EPA, the application is processed in several stages, each of 
which evaluates different elements of the application.
    a. A ``front end'' process assigns administrative numbers, checks 
that basic elements are contained in the application, does a data check 
for formatting purposes, and packages the application for review.
    b. The application package is directed to the appropriate review 
Division and thence to a Product Management (PM) team. Until recently, 
two Divisions, the Registration Division and the Biopesticides and 
Pollution Prevention Division, were the regulatory Divisions which 
reviewed all applications. Antimicrobial pesticide applications were 
processed within one branch, and antifoulants and wood preservatives 
were located in a different branch, both in the Registration Division. 
EPA has established a separate Antimicrobials Division (AD) to help 
focus its regulatory management of these products, and antifoulants and 
most wood preservatives are also now assigned to this Division.
    c. The PM team enters the application into a tracking system, 
reviews product labeling and data compensation elements, and determines 
whether a scientific review is needed. Every application for new 
registration contains some data; the amount and type of data vary 
depending on the type of product, its composition and uses. Even 
applications without new data often require scientific consultation to 
determine the relevance and adequacy of existing data to support the 
application.
    d. If a scientific review is needed, the PM team sends the 
application and data to various scientific reviewers. These reviews are 
generally conducted in parallel, although certain assessments must 
await the results of other reviews (for example, ecological effects 
risk assessment may depend upon the environmental fate profile of the 
chemical).
    3. Upon completion of all reviews, the PM team consolidates review 
recommendations and decisions and determines whether the product can be 
registered. If it can, EPA issues a registration, approves the labeling 
(often with required modifications), and notifies the applicant. If the 
application cannot be approved, the PM notifies the applicant of 
deficiencies (data, labeling, administrative) that must be corrected 
before proceeding.
    Once issued, a registration may be amended by submission of an 
application for amendment, which undergoes a similar review process as 
outlined above. The significant difference is that many amendments are 
administrative, or require no scientific review, and thus entail a less 
intensive and time-consuming process. Often amendments can be handled 
entirely within a PM team. Some minor modifications to registration can 
be accomplished by notification; these are modifications EPA has 
determined have no potential for adverse effects. Notifications require 
the most minimal review, primarily to ensure compliance with pre-
existing Agency policies or guidance.

B. Volume of Work

    Typically, applications for new registration comprise about one-
third of the applications processed by the Agency, but require more 
time and resources per application because of the scientific review 
involved. Applications for registration of new chemicals and major new 
uses require the most resources, but are relatively few in number. For 
sheer numbers, the bulk of registration actions are (and likely will 
continue to be) amendments to existing registrations that require no 
scientific review (so-called ``fast track'' amendments). In FY 1997, 
ending September 1997, EPA received a total of 635 actions related to 
new applications for registration of pesticides assigned to AD, 
including 11 high-resource new chemicals. In addition, there were 1,189 
actions related to amendments to existing registrations, including 61 
high-resource new uses. The number of ``actions'' includes both the 
initial submission of applications for new and amended registration and 
resubmissions of information after EPA has notified the applicant that 
the application is deficient.
    Finally, there were 506 notifications for antimicrobial products, 
which under FIFRA section 3(c)(9) must be reviewed and a decision 
issued within 30 days of receipt. While these require minimal review, 
the large volume coupled with the short review time requires dedicated 
resources.

C. Review Times

    As with any complex process, the speed at which an application can 
be reviewed and a decision made depends upon many things, some within 
the control of the Agency, others dependent upon the applicant. FIFRA 
prescribes in section 3(c)(3) that an application decision be reached 
``as expeditiously as possible.'' Until modified by FQPA, FIFRA 
contained only a single statutory decision deadline of 90 days, for so-
called ``fast-track'' applications--those which require no review of 
scientific data. This review time is predicated upon receipt of a 
``complete'' application. EPA is not required to review and reach a 
decision on a fast-track application until it is deemed to be complete 
(however, EPA must determine whether such an application

[[Page 50680]]

is complete within 45 days after receipt).
    ``Fast-track'' deadlines continue to apply to all products, 
including antimicrobial pesticides. For antimicrobial pesticides, 
however, FIFRA as modified by FQPA imposes additional statutory review 
periods.

D. Non-Regulatory Guidance Documents

    EPA uses detailed guidance documents to amplify, clarify, and 
interpret its regulations in areas such as data and labeling 
development and review, process changes, and applicant 
responsibilities. EPA has developed a number of documents, which are 
available to applicants and registrants, to elaborate on the general 
regulations. In particular:
    1. A guidance document called simply the ``Blue Book'' provides 
specific details about the application process.
    2. The Labeling Manual contains guidance for developing labeling 
which complies with FIFRA and EPA regulations.
    3. The Pesticide Assessment Guidelines describe test methods, 
standards, and data reporting requirements used to satisfy data 
requirements.
    4. Standard Evaluation Procedures describe how EPA will review and 
evaluate each type of study submitted in support of registration.
    5. EPA uses direct notice to registrants (PR Notices) to inform 
them of procedural changes, to clarify and interpret its regulations in 
specific circumstances, and for general information purposes.
    All of these will continue to apply to antimicrobial pesticides. 
Given the special attention FIFRA now focusses on antimicrobial 
products, EPA may develop specific guidance documents for antimicrobial 
pesticides that would augment or replace existing guidance.

VIII. Proposed Antimicrobial Procedures

    This unit discusses in detail the proposed procedural regulations 
applicable to antimicrobial products. Proposed changes that apply to 
all pesticides are discussed in later units of this preamble.

A. Organization of Proposed Subpart W and Relationship to Current 
Regulations

    40 CFR part 152 currently contains regulations pertaining to the 
registration of pesticide products, including antimicrobial pesticides. 
Part 152 contains appropriate definitions and criteria for determining 
whether a product is a pesticide that must be registered (subpart A); 
exemptions from FIFRA requirements (subpart B); procedures for applying 
for registration (subpart C); data compensation procedures (subpart E); 
the Agency's review of an application (subpart F); fees for 
applications (subpart U) (currently suspended), and criteria and 
procedures for classifying a pesticide for restricted use (subpart I). 
Most of these provisions are unaffected by changes in FIFRA that target 
antimicrobial program reform measures, and will continue to apply to 
antimicrobial products as well as other pesticides.
    However, FIFRA section 3(h)(3)(A) requires that EPA propose 
procedural regulations focussing on antimicrobial pesticides. Because 
the statutory reform measures are designed to implement specific goals 
directed at antimicrobial products only, EPA proposes to create an 
entirely separate subpart devoted to antimicrobial registration 
procedures. Proposed new subpart W, entitled ``Registration of 
Antimicrobial Products,'' would be a freestanding subpart describing 
the application and Agency review procedures mandated by FIFRA section 
3(h).
    1. Relationship of subpart W to other subparts in part 152. Subpart 
W would supersede subpart C of current part 152 for antimicrobial 
products only; subpart C would continue to apply to all other products.
    In addition, subpart W--for antimicrobial products only--would 
supersede certain individual sections of subpart F--Agency Review of 
Applications; subpart F would continue to apply to all other products. 
Specifically, the following sections would be superseded:
    a. Sec. 152.104, Completeness of applications. Completeness of 
applications covered by subpart W is contained in Sec. 152.450, 
Contents of application.
    b. Sec. 152.110, Time for Agency review. Review periods for 
applications covered by subpart W are contained in Sec. 152.457, Review 
period for applications.
    c. Sec. 152.115, Conditions of registration. Conditions of 
registration for products covered by subpart W are contained in 
Sec. 152.459, Terms and conditions of registration.
    d. Sec. 152.117, Notification to applicant. Notification of Agency 
decision on an application is contained in Sec. 152.455, Action on 
applications.
    e. Sec. 152.118, Denial of application. Denial of an application 
covered by subpart W is also included in Sec. 152.455, Action on 
applications, although the procedures for denial in Sec. 152.118 are 
cross-referenced in Sec. 152.455.
    As described in Sec. 152.440, all other subparts of part 152 would 
continue to apply to products covered by subpart W and other 
pesticides. Some minor modifications are proposed to current Sec. 152.1 
to properly refer to the antimicrobial subpart. If subpart W and 
subpart F conflict for an antimicrobial product or application, 
Sec. 152.440 states that subpart W would take precedence.
    2. Requirements duplicated in subpart C and subpart W. To be 
comprehensive, avoid confusion for users, and avoid cross-referencing 
unnecessarily, EPA has repeated in subpart W certain elements of its 
current registration regulations from subpart C. In so doing, EPA has 
made minor editorial changes not requiring proposal for clarity and 
organization. EPA has captured the content of the following sections in 
subpart W, and is not requesting comment at this time:
    a. Sec. 152.40, Who may apply, which also appears as new 
Sec. 152.443.
    b. Sec. 152.42, Application for new registration, which has been 
incorporated into new Sec. 152.443.
    c. Sec. 152.43, Alternate formulations, which also appears as 
Sec. 152.444, unchanged.
    d. Sec. 152.44, Application for amended registration, which is also 
incorporated into new Sec. 152.443.
    EPA has incorporated into proposed Sec. 152.443(e) a general 
provision for certification programs at the Agency's discretion and 
direction. Current regulations in Sec. 152.44(b)(2) allow a 
certification submission, in the Agency's discretion, which EPA has 
typically used only for Agency-directed actions. EPA has not to date 
expanded the certification option to a class of actions submitted on 
the applicant's initiative. EPA believes that it may implement 
certification programs administratively without regulations. 
Nonetheless, in light of the statutory provision requiring 
consideration of a certification process, EPA proposes a broader, but 
still discretionary, use of certification programs. Under today's 
proposal, EPA could identify elements of an application that the Agency 
believes are amenable to a certification mechanism. EPA would issue a 
guidance document (typically a notice to registrants) that would detail 
how a certification program would be used.

B. Applicability of Subpart W

    The applicability of subpart W is governed by the statutory mandate 
of FIFRA section 3(h) in the first instance. However, because of 
differences in scope between the statutory mandate and the Agency's 
administration of the antimicrobial program, EPA proposes a

[[Page 50681]]

broader applicability than is provided for by the statute. This unit 
explains why certain products would be covered by subpart W and others 
would not be.
    1. Antimicrobial pesticides and food/feed use antimicrobial 
products are covered by subpart W. Although this proposal reflects the 
mandate of FIFRA to address ``antimicrobial pesticides,'' EPA has 
chosen to cover a broader range of antimicrobial products than 
mandated. It makes sense for these procedural regulations to mesh as 
closely as possible with the Agency's organization and administration 
of the antimicrobial program, so as not to cause confusion either 
within the regulated community or within EPA itself. EPA has created an 
Antimicrobial Division within the Office of Pesticide Programs, whose 
responsibilities extend to all antimicrobial products, not just those 
defined as ``antimicrobial pesticides.''
    Accordingly, EPA proposes that subpart W would apply to both 
``antimicrobial pesticides,'' as defined by FIFRA section 2(mm) and 
antimicrobial products that are food/feed use pesticides, but are not 
defined as ``antimicrobial pesticides'' by FIFRA section 2(mm). 
Virtually all products in these two categories are processed within the 
Antimicrobial Division. The procedures and requirements of subpart W 
would be applied equally to these two categories of products (with the 
exception of review periods).
    2. Wood preservatives and antifouling products are not covered by 
subpart W. This subpart would not apply to any product that is neither 
an ``antimicrobial pesticide'' as defined by FIFRA nor a food/feed use 
antimicrobial product. Inclusion in this subpart would complicate the 
registration process for products not processed in the Antimicrobials 
Division, which are subject to the registration procedures of subpart 
C.
    The status of wood preservatives and antifoulant paints is 
complicated under FIFRA. FIFRA is very specific in defining certain 
types of products as antimicrobial pesticides and excluding other, 
similar products, depending upon the type of claims made for the 
product. A wood preservative or antifoulant paint that makes only an 
antimicrobial pesticidal claim is an ``antimicrobial pesticide'' and 
would be covered by subpart W as an antimicrobial pesticide. By 
contrast, any multi-claim wood preservative or antifoulant paint is not 
an ``antimicrobial pesticide'' and would not be covered by subpart W. 
As a practical matter, because most antifoulant paints assert non-
antimicrobial barnacle claims, they would not be covered by subpart W. 
Likewise, many wood preservatives make insecticidal or fungicidal 
claims and would not be covered by subpart W.
    Under FIFRA section 3(h)(3)(E), certain wood preservative products 
that would not be covered by subpart W may nonetheless be eligible for 
the same review periods as antimicrobial pesticides that are covered by 
subpart W (see Unit VIII.H. for a full discussion of this provision). 
EPA's responsibility for wood preservative products that qualify under 
section 3(h)(3)(E) is fulfilled by ensuring that the statutory review 
period is met. EPA need not, and does not propose to, make subpart W 
apply to these products merely to implement the statutory review 
periods.
    Because the status of wood preservatives and antifoulant paints is 
complex, EPA is providing in Table 1 below a summary of the status of 
these products. The table breaks down wood preservatives and 
antifoulant paints by type of claim (or combination of claims). Column 
1 of the table lists the claim or combination of claims possible; 
Columns 2, 3, and 4 answer the questions posed at the top of each 
column.

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

    3. Applicability is not dependent on where a product application is 
processed. EPA has chosen to extend the proposal to food/feed use 
antimicrobials for practical organizational reasons. However, EPA 
emphasizes that where a product application is reviewed does not in any 
way determine whether subpart W applies. For example, the Antimicrobial 
Division currently reviews most antifoulant products, that for the most 
part are not covered by subpart W. The Antimicrobial Division also 
reviews those wood preservatives that do not make insecticidal claims, 
some of which are covered by subpart W. This allocation of products may 
change based upon workload and resource needs.
    EPA may, in its discretion and for its convenience, choose to treat 
products that are not covered by subpart W as if

[[Page 50682]]

they were covered. For example, EPA currently reviews applications for 
non-covered products within the review periods of Sec. 152.457, but, 
except for the narrow class of wood preservatives discussed above, the 
Agency is not required to do so, and would not be subject to any 
consequences if it failed to meet a review period.

C. Definitions

    Section 152.442 contains definitions that apply to subpart W. 
Relatively few definitions are needed here, since most terms are 
defined elsewhere, either in FIFRA itself or in part 152. Terms 
pertaining to antimicrobial levels of activity (e.g., sterilant, 
disinfectant) are defined in subpart W of part 156, because they are 
used in conjunction with labeling and not with registration procedures. 
Comments are solicited on any additional terms that should be defined 
in subpart W to inform or clarify the subpart.
    Proposed Sec. 152.442 defines the following terms:
    1. The term ``clearance'' is proposed to refer to all types of 
clearances required under a regulatory authority other than FIFRA 
before a product may be marketed. The term encompasses food tolerances, 
exemptions and food additive regulations under FFDCA section 408 and 
409, and FDA clearances for medical devices under FFDCA section 510.
    2. The term ``complete application'' is the general definition 
describing an application that may be placed into formal review. A 
complete application is one that contains all elements described by 
Sec. 152.450, but not necessarily all information required for 
approving a registration or amendment.
    3. The terms ``major new use,'' ``substantive amendment,'' and 
``minor amendment'' are proposed as concise terms for application types 
defined in rather longer phrases in the statute.

D. Types of Applications

    1. What the statute requires. FIFRA section 3(h)(2) establishes 
review period goals for antimicrobial applications, shown in Table 2 
below, and requires in section 3(h)(3) that EPA differentiate in its 
regulations the types of review undertaken for antimicrobial 
pesticides. As discussed in Unit IV.C., EPA intends that defining these 
application types in this proposal, coupled with EPA's part 158 
proposal, will serve to adequately differentiate the types of review 
undertaken by the Agency. EPA proposes in Sec. 152.445 to define 
application types that correspond to the statutory review period goals 
prescribed in the statute. The categories EPA proposes are discussed in 
this unit.

      Table 2.--Statutory Application Categories and Review Periods
------------------------------------------------------------------------
                                            Review period goal
 Description of application type ---------------------------------------
                                         Days               Months

 an amendment)
------------------------------------------------------------------------

 require scientific review of
 data
------------------------------------------------------------------------
Other amendment that requires     90 - 180            3 - 6
 scientific review of data
------------------------------------------------------------------------

    2. Applications requiring FFDCA clearance. The review periods for 
which application types must be described apply only to antimicrobial 
pesticides as defined in FIFRA section 2(mm). That definition excludes 
food/feed use products that require a clearance under FFDCA. Before 
assigning an application to a category having a review period, EPA must 
first exclude any application for a food/feed use that requires a new 
or revised clearance under FFDCA.
    All other antimicrobial pesticide applications fall into one of the 
categories, described in proposed Sec. 152.445(b) for new registrations 
and proposed 152.445(c) for amendments to existing products.
    3. Current application categories. Currently, EPA does not define 
types of applications for registration by regulation, but has a 
detailed tracking system (the Pesticide Regulatory Action Tracking 
System or PRATS) for actions of all types flowing through the pesticide 
review process. The system works by assigning action codes to each type 
of action for purposes of PRATS tracking, reporting and process 
management; the action code definitions are detailed and do not 
correlate exactly with the six described in the statute. The PRATS 
system describes application types and assigns target review periods 
based on features that are not addressed by the general descriptions in 
the statute, including:
    a. The applicant's method of support for the application 
(eligibility for the formulator's exemption, for example).
    b. The amounts and types of data that require scientific review 
(product chemistry or confirmatory efficacy data, for example, require 
minimal review, while toxicology studies require considerable review 
time).
    c. In the case of amendments, what aspect of the registration is 
being amended (composition, labeling).
    d. Whether the application is an initial submission or a 
resubmission following a rejection of an initial application.
    Moreover, combinations of registration actions (for example, a 
change in composition and labeling simultaneously, each with supporting 
data requirements) complicate EPA's task of describing a categorization 
scheme in simple terms.
    It would be costly and inefficient for EPA to develop and manage 
separate tracking systems for antimicrobial decisions and other 
registration decisions. Nor does it make sense to do so. If EPA is to 
successfully manage the review process and track review periods for 
antimicrobial applications, it must use its existing tracking system. 
Accordingly, EPA's approach to defining types of antimicrobial 
applications was to crosswalk the types of applications defined by the 
statute with the descriptors used in PRATS.

[[Page 50683]]

EPA first sorted the categories of actions in PRATS and identified 
those that should be included in one of the six statutory categories. 
EPA then fleshed out the statutory descriptions using the greater 
detail of PRATS action code descriptions for purposes of this proposal. 
The results of this approach are presented in proposed Sec. 152.445.
    4. Terms defined for this proposal. EPA proposes to define more 
concise terms than the statutory ones for the purposes of this proposed 
rule. EPA proposes the following terms: (1) The term ``major new use'' 
for the statutory term ``new antimicrobial use of a registered active 
ingredient''; (2) the term ``substantive amendment'' for the statutory 
term ``amendment to an antimicrobial registration that requires 
sceintific review of data''; and (3) the term ``minor amendment'' for 
the statutory term ``amendment to an antimicrobial product that does 
not require scientific review of data.''
    5. Single category. Because each antimicrobial pesticide 
application type will have a prescribed review period under FIFRA, and 
EPA's failure to issue a decision within that review period will be 
judicially reviewable, each application must be assigned to a single 
application category. Ideally, the applicant and EPA would have a 
common understanding of the designation of an application to avoid 
disputes over the review period. In all situations, the application 
categories in proposed Sec. 152.445 are discrete, that is, there is 
only one possible application type that logically should apply. An 
application either is for a new registration or is an amendment to an 
existing registration. Beyond that broad division, the categories may 
be less well understood and subject to disagreement. Under proposed 
Sec. 152.445(a), EPA would determine the appropriate category.
    There is one situation in which the statutorily designated review 
period cuts across the application types as defined in the proposal. 
The Act sets a review period of 270 days for a ``new antimicrobial use 
of a registered active ingredient'' or ``major new use.'' Proposed 
Sec. 152.445 defines application types in the first instance according 
to whether they are submitted to EPA as applications for new 
registration or amended registration. In the construct of the proposal, 
therefore, an application for a ``major new use'' may be either an 
application for new registration that includes a major new use, or an 
application for amended registration to add a major new use. 
Accordingly, both Sec. 152.445(b) and (c) include a separate category 
for ``major new use. In both cases, the review period would be 270 
days.
    6. Applications for new registration--a. A product containing a new 
active ingredient. Products containing new active ingredients are a 
well-understood category. An application that proposes the registration 
of an active ingredient that has never before been registered falls 
into this category. A product containing a new active ingredient 
typically requires review of considerably more data than one containing 
already registered active ingredients.
    b. A product bearing a major new use. This category consists of an 
application for new registration of a product bearing a major new use. 
A major new use is any use that is not registered for one or more of 
the active ingredients in a product. Typically a major new use would 
involve a significantly different pattern of use that changes or 
increases the exposures to the active ingredient, such that substantial 
amounts of new data are required to evaluate the different or 
incremental risks presented. This definition is comparable to that in 
Sec. 152.3 for ``new use'' for non-antimicrobial products.
    EPA intends in its part 158 proposal to categorize all 
antimicrobial uses into one of the following 12 use categories. All 
currently registered antimicrobial use patterns are included in one of 
these larger use classifications for data requirement purposes, but EPA 
has not to date classified the existing use patterns in this organized 
fashion.
     Agricultural premises and equipment.
     Food handling/storage establishments premises and 
equipment.
     Commercial, institutional, and industrial premises and 
equipment.
     Residential and public access premises.
     Medical premises and equipment.
     Human drinking water systems.
     Materials preservatives.
     Industrial processes and water systems.
     Antifouling coatings.
     Wood preservatives.
     Swimming pools.
     Aquatic areas.
Some categories would be further divided into subcategories. 
Subcategories would generally be defined on the basis of similar 
exposures and data requirements. Examples of significant use/exposure 
differentials among use categories and subcategories are food/non-food 
use and indoor/outdoor use or exposure.
    Using these categories and subcategories of antimicrobial use 
patterns, EPA would regard as a major new use of an antimicrobial 
active ingredient any use in a different use category or subcategory 
from currently registered uses for that active ingredient. As an 
example, an active ingredient is registered with uses in the category 
of ``Materials Preservatives'' and subcategory ``Indoor non-food 
uses.'' If a registrant proposed a new use either in that same category 
for an ``Indoor food use'' (a different subcategory), or in the 
different category of ``Residential and Public Access Premises,'' that 
application would be a major new use of that active ingredient.
    c. A product that is identical to an existing product. For clarity, 
this proposal separates ``identical'' and ``substantially similar'' 
products into two categories, even though they have the same review 
period. Applications for end use products of these types are generally 
indistinguishable from the so-called ``fast-track'' applications of 
FIFRA section 3(c)(3).
    Identical products are those that have an identical composition to 
another registered product and bear identical use patterns. Both active 
and inert ingredients must be identical and in exactly the same 
proportion as the existing product. In the universe of antimicrobial 
products, ``identical'' products include products that are formulated 
by one company and simply repackaged by another company. These so-
called ``repacks'' must be separately registered by the repackager. 
Identical products also include those that are actually formulated by a 
second producer based upon specifications provided by another 
registrant. The significant difference between these two types of 
identical products is that ``repacks'' require virtually no data for 
registration, while those that are produced separately require certain 
minimal ``bridging'' data to ensure that they are actually identical in 
composition and efficacy.
    Identical use patterns mean that the label does not deviate in 
terms of organisms controlled, use sites, or directions for use. An 
applicant's product may have fewer (but identical) claims than another 
registered product and still be an ``identical'' product, but may not 
have different or expanded claims.
    d. A product that is substantially similar to an existing product. 
Substantially similar products are those that are permitted to have 
minor differences in three areas--composition, use pattern, or method 
of data support--from another registered product. When evaluated 
against another identified registered product, a ``substantially

[[Page 50684]]

similar'' product must have the same active ingredients as the claimed 
similar product, in substantially the same proportion. The inert 
ingredients must also be substantially similar in chemical composition 
and functionality to the claimed similar product. For example, 
emulsifiers, fillers, solvents, propellants, etc., in the applicant's 
product must have similar counterparts in the cited registered product 
so EPA can reasonably conclude that both formulated products will have 
essentially the same chemical and physical characteristics and toxicity 
profile. Because substantial similarity may depend on the 
characteristics of the individual products or the active and inert 
ingredients, decisions on similarity would be made on a case-by-case 
basis.
    Substantially similar use means that the product bears a use 
pattern similar to the claimed product. Again, fewer use patterns do 
not make the product dissimilar, but adding or changing use patterns 
would exclude the applicant's product from treatment as a substantially 
similar product. A use pattern is a claim for control of a specified 
organism on a specified site under specified conditions of use. With 
respect to public health products, for which efficacy considerations 
are paramount, use sites must be carefully considered in relation to 
the pest organism, and small formulation changes or variations in use 
directions can mean the difference between an efficacious product and a 
non-efficacious product. For this reason, ``substantially similar'' use 
patterns for public health products would be limited to identical 
organisms on both products. For non-public health products, 
substantially similar use patterns could involve organisms that are 
similar but not identical.
    A similar method of data support means that the applicant is using 
methods of data support that do not require EPA to evaluate data (other 
than product chemistry data) to review the application. As a practical 
matter, this means that the applicant is either citing all required 
studies or requesting a waiver of required studies. Many antimicrobial 
products must be supported by efficacy data of some sort. Such products 
are not substantially similar even if they are similar in composition 
and use pattern to another product, because the submitted efficacy data 
must be reviewed by EPA. Such products would be considered ``other'' 
products.
    e. ``Other'' products. All applications for new registration other 
than new chemicals, identical or substantially similar products, or 
those bearing a major new use, would be assigned to the ``other'' 
category. These are products which have significant differences in 
composition, uses, method of data support or labeling. Proposed 
Sec. 152.445(b)(5) provides examples of applications that would be 
categorized as ``other'' new applications, but is not comprehensive or 
explicit, since it is essentially a default category of application. If 
a new application cannot readily be categorized either as a ``new 
active ingredient'' or as an ``identical'' or ``substantially similar'' 
application, it would routinely be placed in this category.
    7. Applications for amendment. Applications for amendment to an 
existing registration are categorized in much the same fashion as new 
applications, that is, by defining the ends of the review spectrum, and 
placing all amendments not clearly delineated into a middle category. 
EPA therefore defines in this proposal three categories of amendments.
    a. Amendment to add a major new use. As noted earlier, a major new 
use may be presented to EPA in the form of a new registration or an 
amendment. This category is for amendments to add a major new use to an 
existing registration (as opposed to a new registration that bears a 
major new use). ``Major new use'' would be the same as described 
earlier.
    b. Minor amendment. At the other end of the amendment spectrum, EPA 
proposes an application category termed ``minor amendment.'' This 
category is intended to parallel the ``identical or substantially 
similar'' category for new applications, and is also identical to the 
statutorily-defined ``fast-track'' provision of FIFRA section 3(c)(3). 
In no case would a minor amendment require the review of any data. The 
examples in proposed Sec. 152.445(c)(3) list minor amendments not in 
terms of the actual registration changes that might be proposed, but in 
terms of the nature of the evaluation that EPA must do. EPA does not 
believe that this proposal can, or needs to, describe all the possible 
types of ``minor amendments.''
    The following are some characteristics of a minor amendment:
     The evaluation can be conducted entirely within a Product 
Manager team, without any scientific consultation.
     The decision relies only on non-technical, non-scientific 
information readily at hand.
     The decision requires only regulatory or administrative 
judgments, not scientific ones.
     The decision applies existing policy, evaluates adherence 
to existing policy, or ensures consistency among decisions.
    The evaluation consists of simple comparisons among products.
     The evaluation requires no separate documentation (such as 
a scientific review) beyond the decision itself.
    c. Substantive amendment. EPA proposes a category termed 
``substantive'' amendments. This type of application would parallel the 
``other'' category of new registrations, and would encompass all 
amendments that are neither ``major new uses'' nor ``minor'' 
amendments. This category consists of amendments that require the 
review of any scientific data.
    Most changes in label precautionary statements or use directions 
are included in this category, as well as many changes in product 
composition. Inclusion of such a wide variety of amendments in this 
category simply reflects the fact that these changes require the review 
of some data. The data may consist solely of bridging or confirmatory 
chemistry, toxicity, or efficacy data to demonstrate that the product 
and its uses, as modified, would not significantly increase risks, or 
that the product as modified remains efficacious. Moreover, the review 
may be a cursory evaluation of existing data to determine that the 
amendment is adequately supported. Nonetheless, the defining 
characteristic of a substantive amendment is the need to review some 
data, either submitted by the applicant or cited from Agency files.
    This category is the only one in the statute that carries a range 
of review periods (90 to 180 days), a provision that recognizes the 
variety of amendments that can conceivably be proposed to a 
registration. Arguably, the inclusion of a range of review periods 
suggests that there are gradations of application types within this 
range--applications that are relatively less complex that could fall at 
the short end of the review period (90 to 120 days) and others that 
require the full 180 days. Under this interpretation, EPA could be 
expected to establish by regulation subcategories of application to 
which a specific review period within the 90- to 180-day range would 
apply. Equally consistent with the statute would be an interpretation 
holding that the range was included simply to allow EPA the flexibility 
to deal on a case-by case basis with the wide variety of amendments 
covered by this category, and that no further differentiation or other 
regulatory treatment is required.
    EPA adheres to the latter view. EPA does not believe that it is 
statutorily obligated to establish subcategories of 90- to 180-day 
substantive

[[Page 50685]]

amendments. EPA has not discerned any great benefit to the Agency in 
doing so, especially by regulation, while noting a number of 
disadvantages. A proliferation of categories in itself creates 
administrative burdens for EPA in tracking applications. The more 
categories that are created--each having its own description against 
which applications must be judged and a distinct review period--the 
more time it takes EPA generally to administer a tracking system and 
ensure that review periods are met. Likewise, the more EPA is bound by 
regulatory categories and review periods, the less flexibility the 
Agency has to respond to changing review needs or critical priorities 
without running afoul of its regulations. EPA is not precluded from 
adopting administrative subcategories if it does not choose to adopt 
regulatory ones. Moreover, it is not clear that there would be 
significant benefits to applicants in gaining a decision 30 to 60 days 
earlier that would justify the additional administrative burden for 
EPA. Accordingly, EPA is not proposing any specific subcategories. 
Under today's proposal, all substantive amendments would be afforded 
the same review period, that is, a maximum of 180 days.
    In its stakeholder meetings over the past year, however, industry 
representatives requested that EPA solicit comment on whether 
subcategories should be established. Suggestions from the Chemical 
Specialties Manufacturers' Association (CSMA) included the following, 
all of which would be classified as substantive amendments:
    1. Amendment with data to add a ``me-too'' use that requires full 
toxicology and efficacy review.
    2. Amendment with data to change a formulation that requires full 
toxicology and efficacy review.
    3. Amendment with data to modify a label requiring a toxicology or 
efficacy review.
    4. Amendment without data to modify a label which requires a 
toxicology or efficacy review.
    EPA solicits comments on these and other sub-categorizations and 
review periods. Commenters should consider the following factors 
important to EPA's decision:
     A suggested category must be capable of unambiguous 
description. EPA would likely not consider a category of uncertain 
description that could be subject to dispute between applicants and the 
Agency.
     A suggested category must be meaningful in terms of both 
numbers of applications likely to fall in that category and in the 
suggested shorter review period. A category that includes relatively 
few amendments would be equally unsatisfactory as one that includes too 
many amendments. A suggested review period with less than a 30-day 
decrement (180 to 160 days for example) would likely not be considered 
meaningful. Nor would EPA likely adopt a category with a suggested 
review period of 90 days, since there would then be no distinction 
between that subcategory of substantive amendment and a minor 
amendment.
     A suggested category must be comprised of amendments that 
can be reviewed within a review period of less than 180 days without 
jeopardizing EPA's ability to meet other review periods. EPA is 
committed to making decisions on applications as rapidly as possible, 
and currently is meeting the review period goal of 180 days 
consistently for all substantive amendments, but without consideration 
of subcategories.
    If commenters persuade EPA that additional subcategories should be 
established, and that the benefits of less than 180-day decisions 
outweigh the added administrative burdens (bearing in mind that the 
Agency has limited resources and that additional administrative burdens 
mean fewer resources for reviewing applications), EPA may in the final 
rule adopt one or more subcategories of substantive amendments that 
would refine the review period within the 90- to 180-day range. EPA 
will not consider subcategories of any types of applications other than 
substantive amendments.

E. Consultations During the Application Process

    Because EPA is required to process complete applications for 
registration within judicially reviewable timeframes, it is critical 
that applications and data be complete and conform to Agency 
requirements, and, as much as possible, that applicants and the Agency 
have a common understanding of requirements and expectations about the 
process and its outcomes.
    EPA recognizes that the registration process can be complicated for 
persons who are unfamiliar with FIFRA and its requirements; even for 
those who deal routinely with the Agency, keeping up with new policies 
and procedures can be challenging.
    In the past, deficiencies in applications or data have been 
resolved during or after the review process, either informally, for 
example with a telephone call for a minor problem, or formally, by 
rejecting an application with significant deficiencies. The current 
review process has tended to encourage consultation only after an 
application has been rejected, when EPA can explain both the results of 
its review and what an applicant needs to do to correct deficiencies. 
Pre-submission consultation has not typically been the case with 
antimicrobial products.
    With the completeness of an application at stake for an applicant, 
and strict review periods in place for EPA, it makes sense for both to 
consult as much as is practicable and as early as possible. 
Misunderstandings about requirements and expectations may lead to 
needless determinations of incompleteness or denial for the applicant, 
while impeding EPA's ability to reach decisions in a timely fashion as 
required by the statute.
    EPA encourages consultation with the Agency on any application 
prior to a determination of completeness. However, the majority of 
antimicrobial applications are for so-called ``me-too'' products and 
uses, those which are identical or substantially similar to others 
already registered. Such applications are relatively easy to submit 
correctly, seldom raise new or controversial issues, and should not 
routinely require specific consultation. Once an application has been 
determined to be complete, and has been placed in review, the applicant 
should not need or expect to consult the Agency until the end of the 
appropriate review period (which for ``me-too'' products is only 90 
days), or until EPA notifies the applicant of a deficiency.
    However, EPA has identified two areas where it believes advance 
consultation is essential to the submission of a complete application, 
and proposes in Sec. 152.447 to require pre-submission consultation. 
The first is applications for new chemicals and major new uses. These 
consultations, which are common for agricultural chemicals but rare for 
antimicrobial chemicals, help the applicant and the Agency agree upon 
data requirements, data waivers, or issues that typically arise for new 
chemicals and major new uses (such as food use status).
    In addition, EPA proposes to require pre-submission consultation 
whenever an efficacy test protocol or method must be approved by the 
Agency either because there is no protocol or because the applicant 
wishes to modify an exising protocol.
    The regulation does not prescribe how consultation is to be 
accomplished. There is no requirement that a required consultation 
occur in a meeting; a conference call, letter, or other form of

[[Page 50686]]

communication may be sufficient, depending on the nature of the new 
chemical, new use, or protocol approval needs. However, proposed 
Sec. 152.447 emphasizes that any regulatory determinations must be in 
writing. EPA expects the applicant to follow up any consultation with a 
summary of any decisions so that EPA may confirm them in writing. 
Proposed Sec. 152.450 would require written documentation of a 
consultation describing the substance of the consultation to be 
submitted with the application to verify that the consultation took 
place as required.
    In turn, EPA would commit to adhere to the decisions agreed upon in 
a pre-submission consultation unless the circumstances of the 
application change, its determinations were in error, or a question of 
adverse effects arises.

F. Contents of Applications

    1. What the statute requires. FIFRA section 3(h) requires formal 
Agency review only upon submission of a ``complete'' application, and 
requires that EPA clarify its criteria for completeness of an 
application. Current regulations in 40 CFR 152.50 describe the contents 
of an application for registration, including applications for 
antimicrobial products. EPA proposes in subpart W an expanded and more 
detailed description of the contents of a complete application, 
including some new elements of an application not currently required.
    2. Definition of complete application. First, EPA is proposing a 
general definition of ``complete application'' in Sec. 152.3, a 
definition that would apply to all applications for registration. Other 
provisions of FIFRA also link Agency priority, review or action to 
completeness of an application, for example, the fast-track and minor 
use provisions of section 3(c)(3), and the expedited review provisions 
of section 3(c)(10). The general definition is repeated in Sec. 152.442 
to apply to antimicrobial applications.
    The definition draws a distinction between the completeness of the 
application itself (which allows EPA to commence formal Agency review), 
and the completeness of the information needed for EPA to approve the 
application. It is relatively easy to define a core set of items--
forms, labels, routine and uncomplicated data--which, if present in an 
application, suffice to begin review. But completeness for Agency 
decision purposes encompasses an element of ``adequacy'' that, for many 
applications, can only be determined on a case-by-case basis, and only 
during or after substantive review of the application. Accordingly, the 
decision by EPA that an application is ``complete'' (and, for 
``antimicrobial pesticides,'' that begins a review period), represents 
only a preliminary or interim determination of overall completeness 
intended to allow EPA to initiate formal review.
    Completeness becomes a question of adequacy as the amount of 
scientific data and the complexity of the risk assessment increase. 
Typically, applications for new chemicals or new uses, and actions 
involving food uses or increased non-dietary exposures require more 
data. FQPA significantly expanded the scope of dietary risk assessment 
under the FFDCA, particularly for infants and children. 
Correspondingly, EPA will be enhancing its non-dietary assessment of 
risks to infants and children, such as might occur with antimicrobial 
pesticides. However, ``fast-track'' or ``me-too'' applications that 
require little or no scientific review comprise the bulk of 
antimicrobial applications submitted to EPA. These actions are 
relatively straightforward as to application and approval criteria and 
EPA expects that the completeness determinations for review purposes 
and for approval of the application generally would be equivalent. For 
these types of applications, EPA would be less likely to find during 
its formal review that it requires data or information beyond that 
provided at the time of application.
    3. Contents of an antimicrobial application. FIFRA section 3(h) 
requires that, in its final regulation, EPA clarify criteria for 
determination of the completeness of an application for antimicrobial 
pesticides. EPA is proposing in Sec. 152.450 detailed requirements for 
applications, which, if satisfied, would allow a preliminary 
determination of completeness.
    Current requirements in Sec. 152.50 form the basis for the 
requirements in proposed Sec. 152.450, but EPA proposes an expanded 
level of detail. Table 3 below sets out each element of an 
antimicrobial application as proposed today. Column 1 identifies the 
application requirement. Column 2 gives the reference in proposed 
Sec. 152.450 of the requirement. Column 3 gives the cross-reference to 
Sec. 152.50, or indicates that the requirement is new. New elements are 
discussed more fully afterwards. Column 4 provides explanatory notes, 
indicating that a requirement is unchanged from current requirements, 
or describing additions or changes for antimicrobial applications.

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

    4. New required elements of applications. Only three required 
elements of an application are entirely new in today's proposal.
    Proposed Sec. 152.450(j) would require that applicants submit 
documentation of the results of pre-submission conferences, either 
those required by Sec. 152.447 or optional ones, at which regulatory-
related decisions were discussed or agreements reached. The 
documentation could be minutes of the meeting that EPA has reviewed, or 
could be a letter from EPA confirming the decisions reached or 
approving a specific test regimen or protocol.
    Proposed Sec. 152.450(k) would require the applicant to submit 
available reviews of the application, or of individual studies, that 
have been conducted by other regulatory agencies or organizations. If 
an application has been submitted for regulatory review elsewhere, the 
applicant would be required to inform EPA of that fact. Applications 
may have been submitted concurrently to international regulatory 
bodies, or to Federal Agencies or States. If EPA is able to use the 
results of reviews conducted elsewhere, it will save time and resources 
in reaching a decision on the application, which may allow earlier 
entry into the marketplace. An applicant would not be required to 
either await the results of ongoing reviews or to specifically obtain 
copies of the reviews to submit with his/her application. However, if 
reviews have been provided, the applicant would be required to submit 
them to EPA with his/her application.
    Proposed Sec. 152.450(l) would require that applicants provide EPA 
with documentation that they have received (or have applied for) any 
other clearances from Federal agencies that might be necessary to 
market or use the product. EPA currently requires such documentation 
before issuing a registration bearing the use in question. Submission 
with the application of evidence that the clearance has been requested 
or obtained would help assure EPA that the applicant is fully aware of 
its obligations under other laws. Ensuring that all regulatory 
clearances are underway concurrently also makes the review periods for 
EPA meaningful. EPA approval of an application within a review period 
would have little meaning if the applicant cannot market the product or 
users cannot use it because additional clearances are needed.
    5. Non-mandatory or clarified elements of applications. Four 
further elements of the antimicrobial application are either clarified 
by inclusion of explanatory language, or are voluntary information.
    Proposed Sec. 152.450(m)(2) clarifies that product packaging is not 
to be submitted unless requested. The submission of labeling is 
accomplished using draft typescript copies or mock-ups that are 
suitable for microfilming and filing.
    Proposed Sec. 152.450(n) clarifies that applicants are not to 
submit actual product samples with an application unless requested. EPA 
typically requires samples of active ingredients or analytical 
standards in conjunction with

[[Page 50688]]

setting tolerances. EPA may also request samples of antimicrobial 
pesticides bearing public health claims for EPA evaluation of efficacy. 
In each case, EPA will separately request such samples and instruct the 
applicant how and where to provide them.
    Proposed Sec. 152.450(o) provides that applicants who wish to be 
notified whether an application is preliminarily complete (and 
therefore has been placed into review with a review period) furnish EPA 
with a means of notifying them. This could take the form of a postcard, 
form letter, or other means of such notification. Without an easy means 
of notification, EPA cannot commit to written notification. Nor will 
EPA use notification methods such as telephone or e-mail that cannot 
properly be documented by an authorized signature as EPA-originated, 
although advances in technology may make this feasible in the future. 
Finally, EPA would notify the applicant only at the time the 
application is determined to be complete; at that time the formal 
review period would have started, and EPA's next communication with the 
applicant would normally be a decision on the application 
(Sec. 152.455, Action on applications.) EPA would not accept multiple 
postcards or requests simply to advise the applicant of the status of 
the application review during the review period.
    Proposed Sec. 152.450(q) requests, but does not require, that the 
applicant provide authorization for EPA to share the data or EPA 
reviews of data with other regulatory agencies. The ability to share 
data and reviews among regulatory authorities will contribute to 
streamlining EPA review processes for antimicrobial products, and is an 
essential element in achieving harmonization of reviews.
    An applicant who intends to market a product in the United States 
may be required to register the product with individual States; an 
applicant who intends to market the product abroad (such as in Canada) 
must meet the regulatory requirements of other countries. While the 
depth of regulatory scrutiny of a product varies among States and 
countries, many require the submission of equivalent amounts of data as 
the applicant has submitted to EPA. The ability to share data submitted 
to one regulatory authority with others can reduce the paperwork and 
review burden of all by reducing multiple identical submissions and 
allowing the sharing of the review load. EPA already is engaging in 
work-sharing efforts with the State of California and with Canada.
    This effort can be complicated by confidentiality claims under 
FIFRA section 10(b) or the disclosure restrictions of section 10(g). 
Section 10(g) permits the Agency to disclose data in support of 
registration only to those who affirm that they will not further 
disclose the information to foreign or multinational pesticide 
producers. Although a mere claim of confidentiality under FIFRA section 
10(b) does not conclusively prevent disclosure of information, it does 
require the Agency to follow certain procedures (which may include 
obtaining a substantiation of the claim from the registrant) to 
determine whether the information is entitled to confidential 
treatment. These procedures can interfere with free and unimpeded 
exchange of information and data among regulatory authorities.
    On November 27, 1985, EPA issued Class Determination 3-85 (50 FR 
48833). EPA declared as non-confidential (and not subject to the 
disclosure restrictions of FIFRA section 10(g)) reviews of data that do 
not contain information which would disclose: (1) Manufacturing or 
quality control processes; (2) the details of any methods for testing, 
detecting, or measuring the quantity of any deliberately added inert 
ingredient of a pesticide product; (3) the identity or percentage 
quantity of any deliberately added inert ingredient of a pesticide 
product; (4) unpublished information concerning the production, 
distribution, sale, or inventories of a pesticide (such information 
might appear in reviews which discuss the amount of a pesticide sold or 
used in a given time, and thus might concern the significance of data 
from a test or experiment); (5) any complete unpublished report 
submitted to EPA by a registrant or applicant; or (6) excerpts or 
restatements of any such report which reveal the full methodology and 
complete results of the study, test, or experiment, and all explanatory 
information necessary to understand the methodology or interpret the 
results.
    Agency data reviews are normally drafted to avoid inclusion of 
information that is within the six categories described in the 
paragraph above, but EPA cannot guarantee that all reviews will meet 
these criteria. Moreover, as discussed above, the Agency may have a 
need to share raw data in addition to study reviews with States and 
other countries.
    EPA believes it is in the interest of both applicants and the 
Agency to have free and unimpeded exchange of information and data 
among regulatory authorities. To that end, this proposal requests that 
applicants authorize such exchange at the time of application. Sharing 
data and reviews with other regulatory authorities would not compromise 
the protection against disclosure provided by section 10, because such 
sharing would not constitute a public disclosure of the information.
    To authorize data- or review-sharing, the applicant would submit a 
statement authorizing EPA to share either any data submitted with the 
application or EPA's reviews of such data with regulatory authorities 
as needed. An appropriate permission statement would be similar to the 
following:
    This letter grants permission for EPA to share all data submitted 
with this application, EPA reviews of data submitted with this 
application, with State, other U.S. Federal, or other national 
regulatory authorities. This authorization does not waive any 
restrictions on public disclosure of the data reviews.

G. EPA Action on Applications

    1. Completeness screens. EPA currently screens all applications for 
completeness, not just antimicrobial applications. The Office of 
Pesticide Programs Front End Processing Unit (FEPU) receives all 
applications, processes them administratively, and conducts a simple 
screen to ensure that required application items are present and 
properly submitted. An application accompanied by data is subsequently 
screened for submission and format requirements of the data itself. 
Data submissions must include specific items prescribed by Agency 
regulations in 40 CFR 158.32 and 158.33, as well as meet format and 
presentation requirements detailed in PR Notice 86-5. Neither of these 
screens evaluates the substance of the application or the data. In 
either the FEPU or data screen, EPA may identify deficiencies that must 
be corrected. Depending on the nature of the deficiency, the 
application may be placed into review anyway, and deficiencies 
corrected during the review process. This informal screening and 
correction process has served the Agency and applicants well over the 
years.
    Nonetheless, because FIFRA directs EPA to develop completeness 
criteria, and because antimicrobial pesticides are now subject to 
review periods, which are computed only if an application is determined 
to be complete, it is imperative that EPA not only establish more 
formal criteria for completeness, but that EPA conduct a more rigorous 
completeness screen before determining even preliminarily that an 
application is complete. Section 152.455 of today's proposal describes 
what actions EPA

[[Page 50689]]

may take on complete and incomplete applications.
    2. Preliminary determination of completeness. In addition to the 
FEPU administrative screen and the data review screen, the 
Antimicrobial Division has instituted a more in-depth screening process 
to ensure that only applications that meet the standards of proposed 
Sec. 152.450 enter formal Agency review. The antimicrobial screening 
process builds on the earlier screens in two ways: by evaluating the 
adequacy of certain application items that are typically not evaluated 
in a simple administrative screen (e.g., are clearly required studies 
included?), and by evaluating application requirements peculiar to 
antimicrobial pesticides (e.g., efficacy data requirements).
    Based on this screen, EPA would make a preliminary determination 
whether an application is complete (proposed Sec. 152.455(a) and (b)). 
If the application is incomplete, EPA would notify the applicant, 
describe the deficiencies and await resubmission by the applicant. If 
complete, and a self-addressed notification has been provided in 
accordance with proposed Sec. 152.450(o), EPA would notify the 
applicant of the determination, compute the date under proposed 
Sec. 152.457 when a decision may be expected (calculated from date of 
receipt of the application), and place the application into formal 
review. If no self-addressed notification is provided, EPA would place 
the application into formal review, but would not notify the applicant. 
Because some elements of completeness cannot be evaluated until the 
application is reviewed in depth, a determination of completeness 
sufficient to place the application into formal review must, of 
necessity, be a preliminary one.
    EPA is likely to apply its completeness criteria very strictly, for 
several reasons. Strict application of completeness criteria appears to 
be consistent with the statutory direction to base enforceable 
deadlines on completeness determinations. Further, consistent treatment 
of applications is more likely if EPA establishes and adheres to 
relatively ``bright line'' criteria for completeness. Finally, the 
sheer number of applications that EPA receives means that it must 
allocate its review resources very carefully. EPA does not believe it 
unreasonable to use completeness determinations as a management tool 
for those resources. While refusing entry into review for a minor 
deficiency may appear inflexible, it is important to recognize that 
what is flexibility for one applicant may appear to be inconsistency or 
inequity to another. EPA believes that lack of completeness criteria 
and inconsistent application of such criteria have been a source of 
applicant dissatisfaction.
    3. Effect of incompleteness determination on review period. 
Regardless of when a determination of incompleteness is made, the 
consequence is the same: the review period would either not be computed 
or would be halted and recomputed anew upon receipt of all items 
completing the application. EPA would notify the applicant that the 
application is incomplete, and specify how it can be made complete.
    4. Applicant resubmission. Proposed Sec. 152.455(b) specifies that 
EPA will deem the review period to have begun only upon receipt of the 
last item that completes an application. Partial information clearly 
does not satisfy the completeness criteria, or allow the application to 
be placed into review. EPA discourages applicants from correcting 
application deficiencies in a piecemeal fashion; nonetheless, 
historically this has happened (and been tolerated by the Agency) 
because some deficiencies are easy to correct (a form not signed, an 
unreadable draft label), while others may take longer (a missing 
required study).
    An applicant may wish to resubmit rapidly what can be readily 
corrected, and EPA may wish to accommodate the applicant's desire to 
begin review of available information. As noted earlier, under the 
current application review system, both of these can often be 
accommodated. EPA frequently is requested and agrees to place an 
application into review while waiting for some item that has not yet 
been submitted, expecting that the missing item can ``catch up'' before 
it is needed for review. Under the tight review periods provided for 
antimicrobial application review, however, EPA cannot afford the time 
and resources that may be lost if an applicant fails to provide the 
needed information in a timely manner. Other applicants also suffer 
because their applications are not reviewed as promptly as possible. 
Accordingly, EPA would not place an application into review until all 
deficiencies are corrected, and a preliminary determination of 
completeness can be made.
    5. Agency review. Once EPA has issued a preliminary determination 
of completeness, EPA will place the application into substantive Agency 
review. EPA conducts scientific reviews in parallel as much as 
possible, although some reviews depend upon the results of others and 
must be conducted sequentially. Proposed Sec. 152.455(d) specifies 
that, once in review, EPA will complete all reviews for the application 
before issuing a decision of any sort, even a determination that the 
application remains incomplete. EPA intends, however, to continue, to 
the extent practicable, its longstanding practice of communicating 
informally with applicants about interim results of reviews as they are 
completed. Informal communications are not Agency decisions on the 
application itself, and are entirely at the Agency's discretion.
    6. EPA decisions after review. Section 3(h)(3)(F)(i) provides that:

    [T]he Administrator shall notify an applicant whether an 
application has been granted or denied not later than the final day 
of the appropriate review period under this paragraph, unless the 
applicant and the Administrator agree to a later date.

    This provision is probably the single most significant element of 
the overall antimicrobial reform effort mandated by FIFRA. All process 
improvements and efficiencies directed elsewhere in FIFRA section 3(h) 
are for the purpose of shortening review periods to the goals specified 
in FIFRA section 3(h)(2). This provision holds EPA to a decision within 
the review periods that would be established under this proposal. EPA's 
failure to meet those review periods is judicially reviewable.
    EPA takes seriously its mandate for antimicrobial process reforms: 
meeting its review period goals is the most visible and tangible 
evidence of the success of its reforms. Hence, how EPA implements this 
provision, both in making decisions and in managing the review period 
process, is critical.
    EPA review must culminate in one of two specified decisions--
approval or denial--by the end of the review period. The ``review 
period'' can be either that established in proposed Sec. 152.457, or an 
extended review period agreed to between an applicant and EPA. The 
statute does not provide for negotiated shorter review periods; those 
that would be established under this proposal are minimum review 
periods that would apply unless extended by agreement.
    The statute is silent on whether EPA may take other unspecified 
actions prior to the expiration of the review period and what those 
actions might be, but clearly no action other than approval or denial 
is authorized at the end of the review period. EPA believes that it is 
within its discretion to take interim actions prior to the expiration 
of the review period, as long as the final decision on an application 
is either approval or denial. Interim actions might include 
communications with applicants on the application, preliminary 
indications of

[[Page 50690]]

incompleteness or other deficiencies that might lead to denial, or 
notice of the Agency's intent to approve the application.
    Approval is of course the desired decision from the applicant's 
point of view. If the application is complete and relatively 
uncomplicated, reaching a decision within the review period is mostly a 
function of efficient management of the review process. The bulk of the 
antimicrobial applications that EPA receives are for so-called ``me-
too'' products and amendments (those with review periods in the range 
of 90 days). These can be fairly characterized as uncomplicated, and 
problems with completeness are more likely to be the reason for delays 
in approval than the complexity of the review or decisionmaking 
processes. Delays due to incompleteness are not included in EPA's 
review period. A rigorous application of the completeness criteria of 
proposed Sec. 152.450 to weed out incomplete applications should enable 
EPA to reach a decision within the review period for applications that 
are complete.
    For applications of greater complexity--new chemicals, major new 
uses and other products and uses that are not substantially similar--
the decision process is not a straightforward one-time review leading 
to a single decision point of approval or denial. Rather it involves a 
series of decisions, with stops and starts in the process as the 
application progresses. Typically, such an application goes through 
several cycles of review. Under current practice, EPA commences review 
of an application and often determines that it is incomplete, 
inadequate, or raises risk or efficacy concerns that must be addressed. 
The Agency notifies the applicant and places the application into 
pending status until the applicant responds. The ``down time'' awaiting 
applicant response varies considerably based on the type of problem, 
but if a new study is required, may be from 6 months to 2 years. For 
the most complex applications, those for new chemicals and major new 
uses, the cycle may be repeated several times. Thus, the total elapsed 
time from beginning of review to an approval or denial decision may be 
lengthy, but the length is generally not attributable solely to EPA 
inaction or delay. The time may be marked by interruptions when the 
application is awaiting applicant action and not EPA action.
    In the current review process, an interim decision is not a denial, 
which carries the right to administrative appeals. EPA refers to such a 
decision as a ``rejection,'' a term used to reflect the interim 
incomplete status of the application and of EPA's review.
    The provision in FIFRA section 3(h) that EPA must reach a decision 
within a specified review period is silent on whether or how the review 
period should accommodate the cyclical nature of the review process, in 
which EPA review time and applicant response time typically alternate. 
A strict interpretation of the provision would be that the review 
period includes applicant ``down time.''
    Congress rightly anticipated that EPA might reasonably need a 
longer review period in certain circumstances, and the statute 
contemplates, but does not specify, a process for reaching agreement on 
a longer period for the formal approval or denial decision. The 
excepting clause, ``unless the applicant and the Administrator agree to 
a later date,'' while not perfect in that it does not reflect the 
reality of the review process, does allow EPA and the applicant, by 
agreement, to extend the total review period. An agreement on extension 
could be tailored to account appropriately for applicant ``down time,'' 
without penalizing EPA or subjecting the Agency to the threat of 
judicial review. EPA believes that this clause provides much-needed 
flexibility both in the types of actions that EPA may take and the 
process by which an appropriate review period is to be agreed upon.
    Regardless of the reasons for needing an extension, EPA cannot 
afford to engage in case-by-case negotiation for every application that 
might approach the end of its review period without a decision. To 
reflect more closely the actual review process, EPA needs to be able to 
take actions before the end of the review period that have the effect 
of extending the overall review period by stopping it for some period 
of time. Without such flexibility, EPA may be compelled to use its 
denial authority more frequently to meet the statutory requirement to 
issue a decision.
    EPA does not intend to violate its regulations by failing to make 
decisions in a timely manner. If EPA is unable for any reason to issue 
a decision on an application within the review period, and cannot agree 
with the applicant on an extension, EPA's failure permits the applicant 
to seek judicial review. EPA views the judicial process as the least 
desirable means of resolving disputes over the review period. Not only 
is it time-consuming and costly for both parties, but a predictable 
result of judicial review is that a court would order EPA to complete 
review within some further period of time, an outcome which has the 
same effect on the review schedule as if EPA and the applicant had 
agreed to an extension.
    EPA's alternative course of action, permitted by the statute, is 
simply to deny the application. Denial would be governed by the 
provisions of FIFRA section 3(c)(6), which permits an administrative 
hearing process. While EPA may thereby satisfy the requirement to issue 
a decision and avoid the threat of judicial review, the Agency believes 
there is little value added by the administrative hearing process, 
which can be as protracted, costly, and uncertain as judicial review. 
Nor does EPA believe that applicants, many of whom are small companies 
without substantial financial or technical resources, are well served 
by either an administrative or judicial process in this particular 
context. Their objective is presumably to obtain an EPA decision in the 
most timely manner and without extraordinary effort or cost on their 
part.
    Given that individual negotiation is not feasible for any large 
number of applications, that EPA and applicants may reasonably disagree 
on the need for or length of extension, and that neither judicial 
review nor denial of the application is an appealing means of resolving 
such disputes, EPA believes it prudent to establish rules for 
implementation of review periods that build in provisions for 
extension. Today's proposal would do so, while not foreclosing the 
opportunity for case-by-case extension agreements when warranted.
    Accordingly, EPA proposes in Sec. 152.455 a series of possible 
decisions arising from substantive Agency review, incorporating 
proposals for dealing with extensions. These are: (1) The application 
may be approved; (2) the application remains incomplete; (3) the 
applicant has failed to furnish sufficient information to determine 
whether the application may be approved (two circumstances with 
different consequences for the review period); and (4) denial for 
cause.
    7. Approval. If EPA approves the application, it would follow its 
customary procedures to notify the applicant by issuing a Notice of 
Registration or letter of approval for an amendment and sending back a 
stamped copy of the approved labeling if called for.
    8. Opportunity for rebuttal. EPA frequently issues a registration 
that is conditioned upon the applicant's making certain corrections or 
modifications to the registration before sale or distribution. Such 
terms and conditions generally only require changes which are minor in 
nature and

[[Page 50691]]

most often consist of labeling changes to be consistent with similar 
products, adhere to Agency policies, or clarify label statements. In 
EPA's experience, virtually all new registrations require some 
modification to the label; for this reason EPA requests and approves 
draft labeling as part of the application, and requires that the 
applicant submit final printed labeling prior to sale or distribution 
of the product.
    EPA's approval of the registration and permission to distribute or 
sell the product is premised on the applicant's acceptance of EPA's 
terms and conditions. Proposed Sec. 152.455(d)(1) would permit 
applicants who disagree with the terms or conditions of EPA's approval 
to submit an objection within 30 days of receipt of registration. In a 
process analogous to the appeals process for notifications in FIFRA 
section 3(c)(9), EPA would review the applicant's arguments and issue a 
final decision. EPA would try to review the objection and render a 
decision within 45 days of receipt by the Agency. It should be kept in 
mind that EPA's limited resources must be devoted first and foremost to 
its review period obligations for application decisions; EPA cannot 
promise that objections to decisions already made will receive equal 
attention.
    9. Determination that the application remains incomplete. EPA may 
decide that, notwithstanding its preliminary determination of 
completeness, the application remains incomplete. One reason EPA might 
determine incompleteness is if the deficiency is the result of the 
applicant's failure to follow well-established and clearly stated 
guidance, procedures, or policies. Such ``incompleteness'' could be 
identified when studies are reviewed in depth and found not to have 
been conducted in a manner that provides EPA with adequate information 
on which to reach a decision on the application. This type of 
incompleteness would normally be discovered only during substantive 
review. EPA cannot however, preclude the possibility that some 
deficiencies could be overlooked at the earlier preliminary 
completeness screening.
    EPA expects that it would choose to use the incompleteness 
determination only rarely after an application is preliminarily 
determined to be complete, electing instead to deny the application or 
seek agreement with the applicant on an extension of the review period.
    Applications having relatively short review periods (120 
days) are generally straightforward enough that EPA believes it would 
catch most incomplete applications at the earlier preliminary 
completeness screening phase. EPA believes there should be few ``me-
too'' type applications that are determined to be incomplete after 
entering formal review. EPA would rarely seek to extend the original 
review period for these short-term applications since it is 
considerably easier in Agency tracking systems to close out a review 
period altogether than to track an extension. Tracking the review 
period is a time-consuming operation. EPA does not believe it should 
devote its scarce resources to tracking an original review period 
through a series of short-term extensions. This is especially true 
given the high volume of applications that fall into the 
120-day review period.
    With respect to longer review period applications (120 
days), EPA might choose to determine that an application is incomplete 
if a deficiency is discovered early in the review process (e.g., in the 
first 90 days of a 270-day review period).
    If, at later points in a lengthy review period (e.g., 200 days into 
a 270-day review period), EPA judges an application to be deficient for 
reasons attributable to incompleteness, the Agency would want to 
examine why this is occurring. Why are incomplete applications being 
submitted and not being identified earlier in the process? Over time, 
as process improvements continue to be put in place and EPA and 
applicants familiarize themselves with new procedures and requirements, 
EPA expects that incompleteness determinations after beginning Agency 
review would decrease. Nonetheless, EPA must reserve to itself the 
right to determine after placing an application into formal review that 
the application is actually incomplete.
    EPA is not obligated to begin review of or compute a review period 
for an application that is incomplete. If EPA determines after putting 
the application into formal review and computing a review period that 
the application is incomplete, EPA would normally stop the review, 
notify the applicant of its incompleteness, and recompute a new review 
period upon receipt of submission completing the application. Proposed 
Sec. 152.455(d)(2)(ii) specifies this typical result.
    10. Qualifying resubmission for incomplete applications. However, 
in its discretion, EPA proposes in Sec. 152.455(d)(2)(i) to offer 
applicants somewhat more flexibility in Agency review periods if the 
incompleteness determination occurs after putting the application into 
formal review and if completing the application can be accomplished on 
an accelerated basis. For applications having short review periods 
(120 days) and minor incompleteness deficiencies, EPA 
believes that it need not necessarily take the full review period that 
it would be entitled to when the complete application is resubmitted. 
Generally, if a minor deficiency can be corrected within 30 days after 
notice to the applicant, EPA proposes to term that resubmission a 
``qualifying resubmission'' and to complete review within a shorter 
review period than would otherwise be computed. In general, 
Sec. 152.455(d)(2)(i) proposes a subsequent review period 30 days 
shorter than the original base review period for that type of 
application, i.e., 60 days instead of 90 days for an identical or 
substantially similar application, and 90 instead of 120 days for an 
``other new application.'' The choice to offer an abbreviated review 
period is entirely within EPA's discretion; EPA could instead take its 
entire review period.
    EPA proposes to limit such ``qualifying resubmissions'' to 
applications having a review period of 120 days or less. EPA believes 
that the incompleteness deficiencies likely to arise in such 
applications would generally not be multiple deficiencies and are less 
likely to involve serious data deficiencies. By contrast, EPA review of 
an application for a new active ingredient or major new use would in 
all probability identify multiple deficiencies, including data 
deficiencies, not amenable to correction within 30 days.
    11. Determination that the applicant has not submitted all needed 
information. If there are deficiencies other than incompleteness 
deficiencies, the Agency may determine that the applicant has not 
provided sufficient data or information to make a decision on the 
application. EPA proposes two procedures (termed Cases 1 and 2); which 
would apply to any particular application would depend upon the nature 
of the deficiency. In each case, EPA would stop the review period as of 
the date that it notifies the applicant of this decision. In neither 
case would the review period resume until the applicant provided the 
necessary information, and elapsed time with the applicant would not be 
counted against EPA's original review period. The difference lies in 
when EPA would restart the review period (the ``clock''). In Case 1, 
EPA would restart the clock immediately upon receipt of a complete 
resubmission correcting the deficiencies. In Case 2, EPA would restart 
the clock only after an additional

[[Page 50692]]

period after receipt of a complete resubmission.
    Case 1 - Immediate restarting of the review clock. If the 
deficiency is one that can be rapidly corrected by the applicant and 
upon resubmission rapidly reviewed by Agency reviewers without 
significant Agency downtime to re-review, refamiliarize, or reconstruct 
the decision logic, EPA would restart the clock as of the date that the 
applicant resubmitted all information or data required. EPA emphasizes 
that EPA would restart the clock only after all deficiencies have been 
corrected. The resubmission must also be ``complete.'' The kinds of 
deficiencies EPA envisions in this category are short-term studies, 
upgrading an existing study, or providing an explanation of such 
studies.
    If EPA chose this response, the Agency would specify in its notice 
to the applicant the deficiencies needing correction, and require that 
they be corrected within a relatively short timeframe--based upon the 
type of deficiency, probably less than 6 months. If the resubmission 
time is too short, the applicant could suggest a longer time for 
resubmission. If that resubmission time is considerably longer than EPA 
anticipated, such that the Agency would need additional time upon 
receipt to refresh its review, EPA would reserve the right to restart 
the clock at some later time after resubmission (Case 2).
    Case 2 - Delayed restarting of the review clock. For deficiencies 
that take longer to correct (e.g., new studies must be generated) or 
where interruption of EPA review means that EPA must essentially begin 
some portion of its review again, EPA would restart the clock after 
both a period for applicant resubmission and an additional time for the 
Agency to bring the review and reviewer back up to date. The longer the 
interruption of review, the more likely it is that EPA reviewers may 
have changed, that policies may have changed or evolved, or that the 
original reviewer must refresh his/her knowledge of the product, the 
application or the data. In EPA's experience, a review that is 
interrupted for longer than 6 months has become stale.
    In this case, EPA would notify the applicant, specifying the 
deficiencies and requiring correction by a certain date. EPA would also 
estimate how long after resubmission the clock would start.
    12. Negotiating extended review periods for deficient applications. 
FIFRA section 3(h)(3)(F) allows the review period to be extended by 
agreement between EPA and applicants. As noted earlier, EPA intends 
that this proposal set boundary rules for extending review periods, so 
that case-by-case negotiated extensions would be used only 
infrequently. Deficient applications for which EPA would stop the clock 
and restart it, but where EPA cannot define the specifics of the 
resulting extended review period are an area where negotiations would 
be appropriate. Individual negotiation might be appropriate, for 
example, if the deficiency entailed development of new methodology or 
data with which EPA had no prior experience to judge its review time.
    Case 1 - Negotiating resubmission dates for simple deficiencies. 
EPA anticipates it would provide only a limited opportunity for 
negotiation over the appropriate resubmission time for Case 1 
resubmissions. EPA's ability to restart the clock immediately upon 
resubmission and thereafter to meet the review period deadline depends 
on the fact that the deficiency can be corrected rapidly. Simply 
restarting the clock is not feasible if protracted negotiations would 
result in significant delay in resubmission. EPA's concern is not the 
effect of the negotiation per se on the clock (since the clock will 
have stopped upon notification of the deficiency), but the fact that 
any appreciable delay in resubmission because of negotiation may mean 
that the application review would become stale. EPA must strictly limit 
the negotiating time for simple deficiencies, or such deficiencies 
would, because of the passage of time, have to be treated as complex 
deficiencies under Case 2. EPA does not intend in this proposed rule to 
define specific types of simple deficiencies for which Case 1 could be 
used. However, EPA solicits comment on how this procedure could be 
implemented in a realistic manner, and what would be an appropriate 
length of time to allow for negotiations to commence and conclude.
    Case 2 - Negotiating resubmission dates for complex deficiencies. 
Resubmission dates would be more flexible with Case 2 complex 
deficiencies. Because the deficiencies are complex, the resubmission is 
expected to be on a longer schedule. Since time after notification of a 
deficiency until resubmission is on the applicant's clock and not 
EPA's, EPA could be flexible both in negotiating and in the 
resubmission dates established. Unless the deficiency raised serious 
risk concerns for a product already on the market (in which case EPA 
likely would consider denying the application), EPA believes it could 
generally accommodate applicant needs for resubmission.
    In addition to interruption of the review period while the 
applicant corrects deficiencies and resubmits to the Agency, Case 2 
negotiations would need to build in an additional period of time for 
EPA to ``refresh'' the application review before the review period 
clock would start. The appropriate length of this ``delay time'' is 
less easily determined and more likely to be an issue that requires 
negotiation between EPA and applicants. EPA is not proposing either 
specific delay times or criteria for determining appropriate delay 
times in this document, but is proposing to establish the ``delay 
time'' as a regulatory decision.
    The delay time could be based on several factors. First, the delay 
time could be a function of the actual time needed for review of the 
submitted material (which may be one or more new studies). EPA could 
develop some general timeframes for review of particular types of 
studies, for example, a standard review time for a chronic toxicology 
study or an indoor exposure study. These would serve as a starting 
point for determining the delay time. If EPA develops such standard 
review times for studies, it would share these with registrants and 
others before implementing them.
    Second, the delay time could also include the time needed for EPA 
to bring the review and reviewers back up to speed, to adjust for new 
reviewers, and, once completed, to integrate the new material into the 
application review and risk assessment. The longer the clock has been 
stopped and the application put aside, the longer the time needed to 
refresh it and the more likely that changes in personnel or policies 
will have occurred. These times are more variable, but may depend in 
part on the complexity of the application type. The definitions of 
application types in proposed Sec. 152.445 roughly track the complexity 
of an original application review and therefore how much re-review 
might be needed to come up to speed later. EPA expects that the types 
of deficiencies that would trigger a delay time typically would be 
associated with new chemicals and major new uses.
    Finally, the delay time must of necessity take into account 
variable external factors such as competing priorities and workload and 
resource balancing. As a practical matter, although EPA may be able to 
roughly estimate the delay time when it notifies an applicant of a 
deficiency, the actual delay time may be dictated not by circumstances 
at the time of notification, but by circumstances at the

[[Page 50693]]

time of resubmission. Depending on the nature of the deficiency, and 
whether new studies must be generated, resubmission could be a year or 
more away. In that time, substantial changes may have occurred within 
the Agency that cannot reliably be predicted at the time of 
notification.
    For example, EPA could determine that applications requiring a 
particular set of tiered data (ecological effects, for example) 
routinely should require 4 months delay time for a new chemical, taking 
into account the actual review time and the re-review time. Two years 
later, when those studies are submitted to the Agency, EPA could be in 
a situation where its workload has doubled or key personnel are not 
available, leading to a likely delay time of 6 months.
    EPA welcomes comment on how the ``delay time'' decision process 
might be structured and administered for maximum efficiency and equity. 
EPA is considering how and when negotiations on delay times are most 
appropriately conducted. EPA solicits comment on criteria, timing, and 
procedures that could be adopted and whether any of these should be 
regulatory. Realistically, EPA believes that negotiation and agreement 
on an Agency delay time can take place only at or close to the point of 
resubmission. Further, EPA believes that negotiation procedures should 
be informal and non-regulatory to offer the greatest flexibility, and 
at this time is not proposing regulatory negotiation procedures. EPA 
seeks comment on the following questions:
    Criteria. What factors are most important in determining how long 
delay time should be? The type of application? The nature of the 
deficiency? The elapsed or remaining review period? Other priorities?
    Timing. At what point would discussions between EPA and applicants 
be most productive and least demanding of time and resources? Soon 
after notification of deficiencies for planning purposes? Reasonably 
close to the expected date of resubmission? Only after resubmission and 
determination that the resubmission is complete?
    Procedure. Should specific negotiation procedures be developed? Are 
discussions likely to be a frequent occurrence? Should negotiation 
procedures be developed on a case-by-case, as-needed basis? Are 
informal procedures sufficient or is there a need for a regulatory 
framework?
    12. Denial for failure to submit required information (``not for 
cause''). If EPA notifies an applicant of deficiencies, and agrees with 
the applicant on a resubmission date for the application, and the 
applicant fails, without good cause, to submit by that date, or fails 
to submit a ``complete'' resubmission, EPA has the option of denying 
the application. A denial of this type (a ``not for cause'' denial) 
would not be for reasons of potential adverse effects (a ``for cause'' 
denial), but because the applicant has failed to submit the information 
the Agency required to reach a decision on the application.
    Several readings of FIFRA section 3(h)(3)(F)(i) are possible with 
respect to a denial action the Agency may take as the endpoint of a 
review period. EPA believes some interpretations, while plausible and 
logical, would not likely achieve what we believe the Congress 
intended. EPA is instead adopting an interpretation that we believe 
both advances the goal of Congress that the Agency institute reforms to 
improve the antimicrobial decision making process, and preserves the 
rights of applicants under the statutory framework for denials under 
FIFRA section 3(c)(6).
    Under one possible reading of the statute, the Agency would review 
the application under the review periods specified in proposed 
Sec. 152.457, and within those same review periods take all the actions 
required under FIFRA section 3(c)(6) for denials including a 30-day 
notice of intent to deny prior to actual denial. This interpretation 
would effectively shorten the review periods established by section 
3(h) by 30 days, a result that would be particularly acute in the case 
of short review periods such as those of 120 days or less. In 
establishing the review periods, Congress considered the amounts of 
time the Agency requires to review various types of applications. Each 
review period goal was intended to provide a streamlined yet presumably 
adequate amount of time for the Agency to review these applications. 
Congress realized that in some instances these times would not be 
adequate and allowed for the Agency and applicant to extend the 
applicable review period through mutual agreement. We do not believe 
that Congress would on the one hand acknowledge EPA's possible need to 
extend review periods, while at the same time effectively diminishing 
each review period to accommodate the correction period for FIFRA 
section 3(c)(6) denials.
    An equally plausible interpretation is that FIFRA section 
3(h)(3)(F)(i) overrides the provisions of section 3(c)(6) altogether. 
Under this interpretation, EPA would not have to issue a 30-day Notice 
of Intent, or provide opportunity for a hearing. However, there is no 
indication of Congressional intent to diminish the opportunity for an 
applicant to remedy deficiencies and/or request a hearing for denials 
of applications.
    EPA believes a third interpretation is reasonable and more 
appropriate. EPA would regard the Notice of Intent to Deny (NOID) 
required by FIFRA section 3(c)(6) as the practical equivalent of a 
denial under FIFRA section 3(h). At the point a decision is reached 
under Sec. 152.457 (including any extended review periods), EPA would 
commence the FIFRA section 3(c)(6) denial process by issuing a NOID. 
Under this interpretation, the Agency would have the full review period 
contemplated by Congress, and applicants would be afforded the 
protections intended for FIFRA section 3(c)(6) denials. Accordingly, 
proposed Sec. 152.455 would provide that the 30-day NOID itself 
constitutes the denial decision required by section 3(h)(3).
    Denial under FIFRA section 3(h)(3) would be the same as denial 
under FIFRA section 3(c)(6). Legally, EPA would find that the applicant 
has failed to meet the registration standard of section 3(c)(5), in 
that ``its labeling and other material required to be submitted'' do 
not ``comply with the requirements of the Act.'' EPA's determination to 
deny an application would set in motion a process that entails the 
NOID, opportunity for the applicant to correct the application 
deficiencies within 30 days, final denial if deficiencies are not 
corrected, and the opportunity for an administrative hearing process. 
Denial procedures are found in Sec. 152.118.
    EPA would be unlikely to allow additional time for correction 
beyond the 30 days provided by the NOID, for several reasons. First, 
EPA has already notified the applicant previously and agreed upon an 
appropriate time for submitting additional data (of a long-term 
nature). Additional discussion at this point would not seem justified 
in light of the previous negotiations. Second, as noted earlier, EPA's 
tracking system will be strained if EPA must repeatedly recompute the 
elapsed review period due to extensions, new resubmission dates, or 
additional EPA review times. EPA and applicants will not be well served 
if tracking system needs overwhelm the review process. At some point, 
EPA must reach closure on an application. Finally, there is the issue 
of equity among applicants. Negotiating time for any application is 
decreased review time for all applications, and should be allocated 
evenly across applications rather than consumed on a single undeserving 
application.

[[Page 50694]]

    As an alternative, EPA could determine that the failure to resubmit 
properly and on time renders the application incomplete. In either 
case, the effect on the review clock is the same: it would start over 
whenever the applicant submitted the complete data or properly 
completed the application.
    14. Denial for failure to meet the registration standard (``for 
cause''). Finally, as already provided by the statute, EPA can 
determine that an application should be denied because the pesticide or 
its uses pose unreasonable adverse effects on man or the environment (a 
``for cause'' denial). Legally, EPA would determine that it fails to 
meet the registration standard of FIFRA section 3(c)(5)(C) or (D).
    As in the case of a not-for-cause denial, EPA would follow the 
denial procedures of FIFRA section 3(c)(6) and Sec. 152.118. Also as 
noted above, EPA would treat the NOID as the decision required by FIFRA 
section 3(h). EPA expects a denial for cause to be a rare occurrence.

H. Review Periods

    1. Statutory provisions. Although FIFRA section 3(h) is premised 
upon the establishment of decision-making deadlines, it does not 
prescribe a specific set of review periods that EPA must adopt by 
regulation, However, section 3(h) does contain two sets of review 
periods that express Congressional intent in this area. EPA has given 
careful consideration to each, discussed in this unit, and is today 
proposing one.
    First, section 3(h)(2) establishes review time period reduction 
``goals,'' ranging from 90 days to 540 days, whose achievement is tied 
to the implementation of the process reforms required by section 
3(h)(1). Under section 3(h)(1), the explicit purpose of the process 
reforms is to achieve the ``goal'' review periods. The statute stops 
short of requiring that EPA adopt by regulation a set of statutorily-
mandated review periods. The statute appears to anticipate that EPA's 
management reforms might take some time to fully implement to achieve 
the goal review periods: section 3(h)(4) requires EPA to submit an 
annual report to appropriate Congressional committees documenting its 
progress toward the goals. Thus, while EPA is to work toward the goal 
review periods, Congress did not require EPA to adopt the ``goal'' 
review periods in its regulation. EPA may include other review periods 
in the regulation so long as it complies with other requirements 
triggered if the goals are not met.
    Congress did, however, intend that EPA should take the goal review 
periods seriously, and therefore put in place two provisions that are 
triggered if EPA does not meet the goal review periods. The annual 
report mentioned above is to be submitted ``beginning on the date of 
enactment of this subsection and ending on the date that the goals 
under paragraph (2) [the goal review periods] are achieved.'' Thus, as 
long as EPA is not meeting any statutory ``goal'' review periods, for 
whatever reason, it must continue to report to Congress on its 
progress. The first such annual report was issued in October 1997 (EPA 
739-R-97-001).
    Moreover, if EPA issues a final regulation that fails to meet any 
of the goals, it also must comply with the requirements of section 
3(h)(3)(B)(ii) by identifying in the final rule any unmet goal, 
explaining why the goal was not met, describing the elements of the 
regulations included instead, and identifying future steps to attain 
the goal. Again, the statute does not require that EPA propose a 
statutorily-identified set of regulatory review periods, though a 
timeframe is required to be included in the regulation.
    The second statement of Congressional intent, in section 
3(h)(3)(D), establishes ``default'' review periods, ranging from 90 
days to 2 years, that automatically took effect on April 25, 1998, 
since EPA's final regulation was not effective by that date. The 
``default'' review periods are equal to or longer than the ``goal'' 
review periods, depending upon the type of application. After 
promulgation of this regulation, the default review periods will be 
replaced by time periods specified in the final rule. In the 
legislative history of the antimicrobial provisions, it is stated that 
``maximum time periods for review are specified in Subtitle B for 
various activities.'' [Subtitle B contains the amendments in FIFRA 
section 3(h)]. Since the default review periods are in fact the 
``maximum review periods specified'' in section 3(h), this language 
could be read to suggest that Congress intended the default review 
periods to be adopted by the Agency in its regulation. However, EPA 
views the ``default'' review periods as a ``hammer'' provision to 
encourage timely promulgation of its antimicrobial final rule 
containing EPA-specified review periods, rather than a statement of 
Congressional intent as to what review periods should be adopted.
    2. EPA proposal. EPA is today proposing the ``goal'' review 
periods. Since these are the benchmark of the management and process 
reforms contemplated by Congress, EPA believes they are more 
appropriate than any other review periods, which would of necessity 
serve only in an interim capacity until the ``goal'' review periods 
could be met. As an alternative, EPA could consider and would like 
comment on the options of: adopting no review periods by regulation and 
relying on administrative review periods; adopting the ``default'' 
review periods; or adopting some other review periods. Commenters who 
support this last option should be specific as to the review periods 
sought and why. If other than the goal review periods are ultimately 
adopted, EPA would strive to meet the goal review periods, as it has 
since FQPA was enacted.
    Section 152.457 of today's proposal sets out EPA's proposed review 
periods. The three tables in that section address, respectively, 
approvals of new registrations, amended registrations, and ``qualifying 
resubmissions.'' As noted in Unit VIII.D., EPA proposes to review an 
application for a major new use within 270 days, regardless of whether 
that application is a new registration or an amendment to an existing 
registration. Accordingly the tables in Sec. 152.457(c) and (d) both 
include ``major new use.'' Proposed Sec. 152.457 also sets out the 
limitations of applicability of review periods.
    3. Food use antimicrobial products. As defined by FIFRA section 
2(mm), antimicrobial pesticides do not include products whose intended 
use would require a clearance under the FFDCA. As noted in Unit VI.B., 
EPA intends to apply this exception so as to exclude only applications 
that would require a new or revised clearance. Applications subject to 
an existing clearance that does not need revision would be 
antimicrobial pesticides.
    4. Wood preservatives. The statutory definition also excludes 
aquatic herbicides and some wood preservatives and antifoulants from 
definition as ``antimicrobial pesticides.'' Applications for 
registration of such products are not covered by subpart W and are not 
eligible for the review periods of Sec. 152.457.
    However, under FIFRA section 3(h)(3)(E), applications for wood 
preservatives (and only wood preservatives) are eligible for the 
statutorily-required review periods that would be established by this 
proposal if they meet certain conditions:
     First, the application must be for a wood preservative 
that bears an antimicrobial claim as defined in FIFRA section 2(mm), 
even if other non-antimicrobial wood preservative claims (such as 
fungus or insect protection) are made.
     Second, the data requirements to support the wood 
preservative product

[[Page 50695]]

that is not an ``antimicrobial pesticide'' must be the same as the data 
requirements that support a wood preservative that is an 
``antimicrobial pesticide.'' In general, the data requirements in part 
158 are the same for all wood preservatives, regardless of the type of 
wood preservative claim made. Thus, all wood preservative products 
fulfill this criterion.
     Finally, the applicability of the statutorily-required 
review period to a wood preservative application is to be ``consistent 
with the degree of risk posed by the use of the wood preservative.'' 
EPA interprets this clause to permit the Agency, in its discretion and 
on a case-by-case basis, to determine that an individual wood 
preservative application is not subject to the statutorily-required 
review period based on risk concerns.
    For example, EPA might exercise this discretion for an application 
that initially would have a review period of 180 days. During the 
review, however, EPA discovers that the wood preservative use poses 
significantly greater risks than a typical ``substantive new use'' 
application. This might occur if the treated wood were intended for use 
in a manner that greatly increased or changed the exposure potential to 
humans or other species. To evaluate the increased risk, EPA might need 
more than 180 days, even if substantial new data were not required. In 
this situation, EPA would notify the wood preservative applicant that 
the application was no longer entitled to a statutorily-required review 
period, and specify the risk reasons therefor.
    EPA would make every effort in its notification to estimate when 
the application review would be completed, although the application 
would no longer qualify for review period coverage. EPA regards its 
notification to the wood preservative applicant of a risk differential 
basis for review as relieving EPA of its obligation to complete review 
within any statutorily-required review period.
    5. Fast-track applications. Fast-track applications are described 
in FIFRA section 3(c)(3). Fast-track applications are not limited to 
antimicrobial products, and EPA is required to reach a decision on the 
application within 90 days. Currently, there are no regulations for 
fast-track applications, and none are needed because the statute sets 
out clear deadlines for completion of review. The review period for an 
antimicrobial pesticide specifically does not affect or substitute for 
the timeframe for a fast-track review of an antimicrobial pesticide. 
Generally, antimicrobial applications for identical or substantially 
similar new products or minor amendments are equivalent to fast-track 
applications, and would be decided under either provision within 90 
days.
    As a legal matter, however, an application must be reviewed either 
as a fast-track application or an antimicrobial application--a single 
application cannot be both. EPA interprets FIFRA section 
3(h)(3)(F)(iii) to place an application that could qualify as either a 
``fast-track'' or ``antimicrobial pesticide'' application squarely 
under the antimicrobial provisions and review periods. While there are 
minor procedural differences between 90-day fast-track decisions and 
90-day antimicrobial review period decisions, the significant 
difference between the two is that a fast-track action is not 
judicially reviewable if EPA fails to render its decision within 90 
days while an antimicrobial action is judicially reviewable.

IX. Duration of Registration for Products Bearing Public Health 
Claims

    EPA proposes in Sec. 152.458 to establish terms for a time-limited 
registration of products bearing a public health claim. The term of a 
registration would be limited to no more than 5 years. The registration 
could be continued only if the registrant conducts product analysis and 
efficacy testing that confirms that the product continues to meet the 
applicable registration standards of FIFRA section 3(c)(5). EPA 
believes that it is authorized to establish this provision under the 
authority of sections 3(h) and 25(a).

A. Statutory Requirements

    FIFRA section 3(h)(3)(A)(ii)(IV) mandates two things: (1) that EPA 
``. . . ensure that the registration process is sufficient to maintain 
antimicrobial pesticide efficacy''; and (2) that ``antimicrobial 
pesticide products continue to meet product performance standards and 
effectiveness levels for each type of label claim made.'' Section 3(h) 
focuses on the registration process as a means of ensuring continued 
product performance. More important, however, is the strong 
Congressional directive to ensure continued product performance and 
effectiveness after registration. Thus, under section 3(h), EPA must 
address post-registration efficacy in the antimicrobial regulation 
proposed today.
    EPA is also authorized under FIFRA section 25(a) to issue 
regulations to carry out the provisions of the Act. Such regulations 
must specifically ``take into account the difference in concept and 
usage between various classes of pesticides, including public health 
pesticides and differences in environmental risk and the appropriate 
data for evaluating such risk between agricultural, nonagricultural, 
and public health pesticides.'' ``Public health pesticide'' is defined 
in FIFRA section 2(nn) to include, among other things, pesticide 
products intended for use against ``viruses, bacteria, or other 
microorganisms . . . that pose a threat to public health.'' The 
references in FIFRA section 25(a) singling out public health pesticides 
were added by FQPA, and EPA regards their addition as expressing 
Congressional intent that public health pesticides as a class should be 
distinguished from other pesticides when considering regulatory 
requirements, including this proposal.
    Taken together, EPA believes that the clear Congressional intent 
expressed in section 3(h) to ensure post-registration product 
performance and effectiveness, coupled with the authority conferred by 
section 25(a), authorize EPA to establish by regulation binding 
requirements on registrants of antimicrobial public health products to 
ensure continued product efficacy. The requirements relate to initial 
registration and also extend into post-registration activities.

B. Alternatives Considered

    As noted in Unit IV.E., EPA has relied on enforcement mechanisms to 
ensure post-registration efficacy; EPA will continue to use these as 
appropriate. But, because failure of an antimicrobial public health 
product to work as intended cannot normally be detected by the user and 
can have serious health and safety consequences or other unreasonable 
adverse effects, it is critical that EPA use all available regulatory 
and enforcement mechanisms to ensure public health protection.
    One means of ensuring continued efficacy after registration would 
be through the statutorily required re-review of products. FIFRA 
contains two provisions that require EPA to reassess each registration 
according to the latest scientific standards, which for public health 
products would include an efficacy review. FIFRA section 4 requires a 
one-time reregistration of each product first registered before 
November 1984. This process is underway, but to date few antimicrobial 
products have been reviewed under section 4, and products registered 
since 1984 are not subject to reregistration. Additionally, FIFRA 
section 3(g) requires EPA to periodically review each registration, 
with a goal of re-reviewing each product every 15 years.

[[Page 50696]]

    Although these provisions will be useful in ensuring that pesticide 
products continue to meet the registration standard, based upon up-to-
date scientific standards, EPA believes that more product oversight is 
needed to meet the mandate of FIFRA section 3(h) to ensure continued 
efficacy of antimicrobial public health products. Neither a one-time 
re-review nor a periodic review only every 15 years offers adequate 
assurance of continued efficacy of products so critical to public 
health protection. EPA believes that by requiring the re-testing of 
products at more frequent intervals than every 15 years, complemented 
by EPA, State and other testing programs, it can be better assured of 
continued product efficacy, without incurring to itself or imposing 
upon registrants significant additional costs.
    Alternatively, EPA could establish, or require registrants to 
establish, an ongoing quality control and efficacy monitoring program 
to evaluate product composition and efficacy on a frequent basis. EPA 
conducted a one-time testing of sterilant products, and is conducting 
similar testing of hospital disinfectant products. EPA believes that 
many antimicrobial registrants, fully aware of the need for continuing 
quality control and efficacy, already test their products on a routine 
basis, although EPA currently has no data on the number of producers 
who do so, the type of testing conducted, or how frequently it is done. 
A formalized testing program, whether by EPA or registrants, would 
obviously be one way to meet the mandate of FIFRA section 3(h), and, if 
conducted at frequent intervals, would offer the greatest assurance of 
continued product performance and public health protection. EPA itself 
does not have the resources to establish and sustain such a program, 
and so EPA proposes that registrants bear the cost of such testing. Two 
approaches have been considered, and one is being proposed today.
    One such method would be to require that a public health applicant 
develop and submit for Agency approval as part of his/her application 
for registration or reregistration a plan for continuous quality 
control and efficacy testing. Such a requirement would meet the mandate 
of using the registration process to ensure efficacy, as well as 
ensuring continued post-registration needs. Upon approval of the 
registration or reregistration, the plan would become a term of the 
registration and would be binding on the registrant. The benefit of 
this approach is that public health applicants would be afforded the 
greatest flexibility to design a program that they believe satisfies 
the needs of the Agency. However, approval of a plan would require 
greater review resources for the Agency, and potentially lead to delays 
in approval beyond the established review periods required by 
Sec. 152.458. Comments are requested as to the value, feasibility, and 
potential costs of such a requirement, as well as criteria for 
evaluating plans. EPA is not proposing this option today, but could 
adopt it in the final rule. If EPA does so, it would include the 
requirement for a public health quality control and efficacy monitoring 
plan in Sec. 152.450.
    EPA seeks information on current registrant- or producer-imposed 
quality control measures, whether producers are currently routinely 
conducting efficacy testing on a batch basis or at frequent intervals, 
and what type of testing is conducted. Finally, comments are solicited 
on any additional ways of ensuring continued efficacy of public health 
products; suggestions would be considered for future implementation, 
either administratively or by regulation.

C. Sunset Provision

    1. Maximum 5-year registration term. EPA proposes to implement a 
periodic and regular testing program by limiting the duration of a new 
antimicrobial public health registration to no more than 5 years from 
the date of initial registration of the new product. EPA would 
incorporate the 5-year expiration into the approval of the application 
as a term of registration. Every 5 years, in order to avoid expiration, 
the registrant would have to conduct the testing described in 
Sec. 152.458(b)(3) and certify that the product has passed the tests.
    The Agency is also proposing to require testing every 5 years as a 
prerequisite for maintaining the registrations of existing products, 
i.e., products registered as of the effective date of the rule. For 
existing products, the 5-year period would begin on the earliest of: 
(1) The date of first amendment after the effective date; (2) the date 
of reregistration under FIFRA section 4; or (3) a date certain 
approximately 6 months after the effective date of the rule. EPA would 
in the final rule specify the date certain, which, based on current 
projected schedules, would be no earlier than August 1, 2000. This last 
date would ensure that all products registered at the time the rule 
becomes effective would be brought into the retesting scheme. EPA 
expects that this default date would govern for most existing products, 
since the number of amendments and reregistrations that could be 
expected in the 6-month period is unlikely to approach the number of 
public health registrations (currently estimated at approximately 3,000 
products).
    In the case of an amendment or reregistration, EPA approval letters 
would include the 5-year requirement. Because there would otherwise be 
no Agency notification for products that become subject on the specific 
default date, EPA would notify all such registrants of the effective 
date.
    EPA is proposing this phased introduction of the testing 
requirement for existing products because it believes that phased 
testing will create less strain upon laboratory demand for testing and 
upon Agency resources. It would, however, complicate the tracking of 
expiration dates.
    As an alternative, EPA could begin the 5-year retesting requirement 
on a single date for all existing products. While this would ensure 
equity for existing products and simplify calculation of expiration 
dates for both registrants and the Agency, it could lead to high demand 
for laboratory testing on a compressed schedule every 5 years. Even 
with a single date for existing products, new products would become 
subject to the retesting requirement on a phased basis as they are 
registered; thus, there would always be some phasing of the retesting 
requirement. Over time, as new products are registered and existing 
ones taken off the market, the phased testing scheme would become the 
norm rather than the exception. If EPA were to adopt a single date, it 
would specify the date in the final rule.
    In any case, the scope of EPA's determination of continued 
registrability at the 5-year intervals would be limited to the 
composition and efficacy standards in FIFRA section 3(c)(5)(A) and (C), 
i.e., that the product's composition ``is such as to warrant the 
proposed claims for it,'' and that ``it will perform its intended 
function [without unreasonable adverse effects on the environment].'' 
EPA's evaluation would be limited to products bearing public health 
claims and its determination to whether the product would perform its 
intended function at the antimicrobial levels claimed. EPA would not 
expect to reevaluate the potential adverse effects of the product every 
5 years, but generally would reserve such evaluation for a 15-year 
review cycle. Thus, in any given 15-year period, EPA typically would 
review each product once under the 15-year statutory review provision 
and 3 times for efficacy purposes. Notwithstanding these scheduled 
review intervals, EPA may conduct a review of a product for any purpose 
(including, but not limited to, efficacy

[[Page 50697]]

concerns) at any time and take regulatory or enforcement action based 
upon its findings.
    EPA believes that a quality control check and efficacy evaluation 
at least every 5 years is needed to ensure continued efficacy. However, 
the Agency solicits comment as to whether a different registration term 
should be implemented, either more or less than 5 years.
    2. Data requirements. To meet the product composition standard, 
proposed Sec. 152.458 would require a chemical analysis demonstrating 
that the product conforms to the composition approved by EPA on the 
most recent Statement of Formula, conducted according to the analytical 
method that the registrant is required to provide the Agency under 40 
CFR 158.180.
    To meet the product efficacy standard, proposed Sec. 152.458 would 
require that the registrant conduct the battery of efficacy tests that 
would be required to support the product if it were submitted for new 
registration at that time, conducted in accordance with the most 
current Agency testing guidelines. Testing guidelines for antimicrobial 
products are evolving, and testing would have to reflect the methods 
and standards recognized by EPA at the time of the required testing.
    To ensure that the testing reflected the product as distributed and 
sold at the 5-year mark, the testing would have to be conducted during 
the final year of the 5-year registration period (or other renewal 
period if 5 years is not selected). Although EPA believes it is in the 
interest of registrants to conduct such analysis and testing more 
frequently as a matter of good business practice, only testing 
conducted within the last year could be used to support renewal of 
product registration.
    3. Certification procedure for compliance. EPA believes that it can 
accomplish this limited renewal program and monitor compliance without 
routinely reviewing the actual test results. In accordance with the 
mandate of FIFRA section 3(h)(3)(B)(iii) to ``consider the 
establishment of a certification process for regulatory actions 
involving risks that can be responsibly managed . . . in the most cost-
efficient manner,'' EPA proposes to use a certification process as the 
most cost-effective means of administering the program. Each registrant 
would certify in writing to the Agency that the testing had been 
conducted as required in accordance with EPA Good Laboratory Practice 
Standards, and that the results demonstrate that the product meets the 
composition and efficacy standards specified. The certification must be 
signed by an authorized representative of the registrant. As a 
condition of registration, EPA would require that test results be made 
available immediately to EPA upon request; EPA expects that it would 
selectively review the data for some products.
    The required certification would have to be submitted to the Office 
of Pesticide Programs no later than 90 days prior to each successive 
expiration date of the registration, to allow sufficient time for EPA 
to process it and notify the registrant of its determination. If at any 
time after the renewal, the Agency determined that the certification 
was false or the data upon which it was based do not support the 
certification for any reason, the registration would be subject to 
regulatory or enforcement action or both.
    4. Failure to submit. EPA would not notify registrants of the 
upcoming expiration of their product registrations. Registrants would 
be responsible for monitoring the status of their registrations, 
conducting the testing and submitting the required certification in a 
timely manner. Failure to submit would result in the expiration of the 
registration automatically and without hearing rights. If the 
registration expired, the registrant would have to submit a new 
application for registration to once again market the product.
    If EPA has no other information or data to suggest that the product 
is no longer efficacious, EPA would permit the registrant 90 days to 
distribute and sell his/her existing stocks of product (product in 
existence on or before the date of registration expiration). Product 
already distributed by the registrant and in channels of trade could be 
distributed and sold for 1 year after expiration.
    5. Products that fail efficacy testing. If a product fails efficacy 
testing at its 5-year renewal, the registrant would be unable to 
certify as required by Sec. 152.458, and the product registration would 
expire at its 5-year anniversary.
    Moreover, there is a continuing obligation under FIFRA section 
6(a)(2) to report information concerning adverse effects to the Agency. 
In certain cases this obligation extends beyond the life of the 
registration (for example, to an expired registration). If the 
registrant conducts efficacy testing at any time, and the product fails 
to meet the performance standard of part 156, subpart W, for each 
public health claim, the registrant is required to report such failure 
to EPA in accordance with the procedures and timeframes in 40 CFR part 
159. Section 159.188 specifically details the information required to 
be submitted concerning antimicrobial public health products. The 
requirement to submit under FIFRA section 6(a)(2) and the regulations 
in 40 CFR part 159 is a separate requirement from that under this 
proposal.

X. General Conditions of Registration

    EPA proposes in Sec. 152.459 to establish conditions of 
registration for antimicrobial pesticides. Under FIFRA section 3(c)(7), 
EPA is authorized to register pesticide products conditionally. Current 
regulations in Sec. 152.115 implement EPA's authority, and specify 
general conditions applicable to registrations. Section 152.115(c) 
permits EPA to establish, on a case-by-case basis, other conditions 
applicable to registration under FIFRA section 3(c)(7).
    For antimicrobial pesticides, EPA proposes in Sec. 152.459(a) to 
cross-reference the conditions of Sec. 152.115. These conditions relate 
primarily to submission of missing data subsequent to registration.
    Further, EPA proposes to establish as a condition of registration a 
requirement that registrants of non-public health products submit 
efficacy data upon request by the Agency. Registrants are currently 
required to maintain efficacy data for non-public health products, but 
EPA does not routinely review them as part of the application. Upon 
request, registrants are required to submit the data. When this request 
is made prior to approval of a new application, EPA can refuse to 
register the product if the registrant does not comply. EPA proposes in 
Sec. 152.459(b) to establish as a condition of registration that 
registrants must submit upon request any efficacy data for a non-public 
health product that were not required to be submitted with the 
application. By establishing submission as a condition of registration, 
EPA makes explicit the authority and action it will take (expedited 
cancellation under FIFRA section 6(e)) if registrants fail to provide 
these data after registration.

XI. EPA/FDA Jurisdiction Over Antimicrobial Products Used in or on 
Food

A. Background

    Since EPA was created in 1970, EPA and FDA have shared authority 
under FFDCA over pesticide residues in food. Prior to FQPA, the 
division of jurisdiction between EPA and FDA was governed by a number 
of somewhat complicated provisions of FFDCA. FQPA modified the FFDCA to 
create much clearer lines of jurisdiction. In the

[[Page 50698]]

process, FQPA transferred to EPA regulatory responsibility for a number 
of antimicrobial substances which for many years had been under FDA 
jurisdiction.
    In the 2 years after FQPA enactment, EPA and FDA held extensive 
discussions on their respective legal authorities pre- and post-FQPA. 
The two agencies issued a joint Federal Register notice entitled 
``Legal and Policy Interpretation of the Jurisdiction under the Federal 
Food, Drug, and Cosmetic Act of the Food and Drug Administration and 
the Environmental Protection Agency over the use of Antimicrobial 
Substances with the Potential to Become Components of Food'' 
[hereinafter ``Policy Interpretation''] issued in the Federal Register 
on October 9, 1998 (63 FR 54532) (FRL-5773-8). In that notice EPA and 
FDA discussed a proposed allocation of jurisdiction over antimicrobial 
substances which would transfer back to FDA regulatory authority over 
many of the substances that had been transferred to EPA in 1996 by 
FQPA.
    EPA would have effected the transfer in a subsequent regulation by 
revising its declaration of a FIFRA ``pest'' in Sec. 152.5 to exclude 
certain microorganisms occurring in food processing facilities, 
packaging and food contact articles. Readers are referred to the Policy 
Interpretation for a full discussion of the proposed approach.

B. FDA Regains FFDCA Jurisdiction

    On October 30, 1998, however, Congress passed the ``Antimicrobial 
Regulation Technical Corrections Act of 1998'' (ARTCA), Public L. 105-
324, which amended FFDCA section 201(q)(1) and 408(j) in a manner that 
essentially accomplished the two Agencies' planned regulatory approach, 
and obviated the need for EPA to issue regulations. ARTCA supersedes 
the Policy Interpretation with respect to FFDCA regulatory authority 
over antimicrobial residues in food except for residues of ethylene and 
propylene oxides, which were retained as ``pesticides.'' ARTCA, 
however, does not address the interpretation of the FIFRA term 
``processed food'' that was included in the Policy Interpretation.

C. EPA Retains FIFRA Jurisdiction

    Under the Policy Interpretation, EPA intended to propose to yield 
both FFDCA and FIFRA authority over those antimicrobial substances 
addressed in the Policy Interpretation. EPA and FDA viewed the 
regulatory approach of redefining FIFRA ``pests'' to be the best means 
of accomplishing the transfer agreed upon between the Agencies. No 
authority under FFDCA would have achieved this objective before passage 
of ARTCA.
    Unlike the proposed change discussed in the Policy Interpretation, 
however, the statutory change put in place by ARTCA affects only FFDCA 
authority over antimicrobial residues in food. ARTCA does not affect 
the status of any substance as a ``pesticide'' within the meaning of 
FIFRA. The legislative history of ARTCA makes this point clear:

    This amendment would affect the regulation of antimicrobial 
pesticides only under the FFDCA. EPA would continue to regulate 
antimicrobial pesticides under FIFRA, and EPA's authorities under 
that statute would not be changed.

    In light of ARTCA, which provides specific Congressional direction, 
EPA is not proposing to exclude or exempt these products from FIFRA 
requirements, as discussed in the Policy Interpretation.
    Because the legislation is complex, EPA has developed an overview 
table of current FFDCA authority post-ARTCA. Table 4 below is an 
overview of antimicrobial substances whose use may result in residues 
in food. Column 1 lists the category of antimicrobial substances. 
Column 2 further subdivides the major categories. Column 3 gives the 
current jurisdiction under FFDCA over antimicrobial substances after 
ARTCA. Note that, even where FFDCA authority is vested in FDA, EPA 
retains FIFRA authority for antimicrobial products other than those 
used on processed food. Such products will continue to require 
registration.

XII. Efficacy Performance and Labeling Standards for Antimicrobial 
Products

    EPA proposes to create a new Subpart W (Secs. 156.440 through 
156.458) in part 156, entitled Public Health Claims for Antimicrobial 
Pesticides. Subpart W would establish labeling requirements for 
antimicrobial pesticides that make public health claims based upon the 
level and type of efficacy demonstrated by testing. The efficacy 
performance standards upon which the proposed requirements are based 
are derived from the testing requirements of 40 CFR part 158, and the 
test methods and standards provided in Subdivision G of the Pesticide 
Assessment Guidelines. Today's proposal would also codify certain 
labeling requirements that are currently applied to antimicrobial 
pesticides individually at the time of registration, but are contained 
only in Guidelines (Subdivision H of the Pesticide Guidelines). Neither 
the performance standards nor the labeling requirements are a departure 
from current and longstanding policies.

A. Need for Rule

    EPA bears a special responsibility to ensure that antimicrobial 
efficacy for public health products be substantiated and maintained 
over the life of the product because of the potentially serious 
consequences of lack of efficacy, and the fact that users cannot 
independently ascertain product efficacy. For that reason, EPA not only 
must review antimicrobial efficacy data to ensure that products indeed 
perform at the claimed level of antimicrobial activity, but also must 
assure that product labeling accurately expresses the type and level of 
activity to be expected. Effective control of public health pests is 
not only a function of the availability of products that work as 
intended, but also of users' ability to select an appropriate product 
for their needs, and to use it properly. The product labeling is 
critical in conveying this information. By issuing performance 
standards and associated labeling standards as rules rather than the 
current Guidelines, EPA expects to ensure consistency in labeling, 
promote a common understanding among registrants and the user community 
of performance expectations and limitations, and thereby maintain the 
benefits of these products in protecting public health.

B. 1984 Proposal

    EPA originally proposed these performance and labeling standards in 
substantially similar form in 1984 as part of a larger general 
pesticide labeling proposal (September 26, 1984, 49 FR 37959), but did 
not finalize them. Because of the intervening time, EPA is reproposing 
those efficacy performance and labeling standards today. In response to 
the 1984 proposal, EPA received eight comments pertaining to the 
efficacy performance and labeling standards. The commenters included 
two trade associations (the Chemical Specialties Manufacturers' 
Association and the International Sanitary Supply Association), and six 
individual producers of antimicrobial pesticides. A copy of these 
comments or a summary is available in the public docket. EPA has not 
reviewed these comments in detail for this new proposal, and invites 
commenters to reiterate any comments they believe are relevant to this 
proposal.

C. Current Proposal

    Every pesticide product must be properly labeled, in accordance 
with general labeling requirements of part 156, including, among other 
things, use directions that describe the site of application, the 
target pests associated with each site, the dosage rate, the method of 
application, the frequency and timing of application and any particular 
limitations on use. Antimicrobial products covered by subpart W must 
comply with part 156 labeling requirements. In addition, for public 
health antimicrobial products, the labeling must identify the type and 
level of antimicrobial activity demonstrated by efficacy testing. A 
product that does not meet the applicable performance standard of 
proposed subpart W for a specified level of activity (such as 
sterilizer, disinfectant, or sanitizer) or type of activity 
(tuberculocidal, virucidal) may not be identified as such on the label, 
and, in some cases, will be required to bear a disclaimer to make clear 
the limitations of product performance.
    Under proposed Sec. 156.440, the applicability of subpart W to 
antimicrobial products is the same as that in part 152, subpart W. This 
will clarify that all antimicrobial public health products, not just 
those meeting the definition of ``antimicrobial pesticide,'' are 
subject to the efficacy performance and labeling standards. This 
clarifies the status of food use antimicrobials, which are excluded 
from the statutory definition, but covered under EPA's proposed rule.
    However, proposed Sec. 156.440 would limit applicability of subpart 
W to end use products. EPA does not expect manufacturing use products 
to make specific public health claims. Typically a manufacturing use 
product must be supported by presumptive efficacy testing demonstrating 
that the active ingredients are capable of antimicrobial activity. The 
labeling typically bears information on the results of these screening 
or presumptive efficacy tests. End use products must, however, be 
supported by specific efficacy data on the end use formulation, on the 
sites and under the expected conditions of use of the product itself. 
The performance standards on which the labeling standards of subpart W 
rely are based upon end use product testing, not presumptive testing of 
manufacturing use products. The labeling statements and limitations 
therefore would also relate only to end use products.
    Proposed Sec. 156.441 contains pertinent definitions, including the 
levels of antimicrobial activity that are permitted on labeling (e.g., 
sterilizer, disinfectant, sanitizer). This listing is not necessarily 
exhaustive; in the future, EPA may define additional categories of 
antimicrobial activity or public health pesticides.
    Proposed Sec. 156.443 describes what types of claims EPA considers 
to be public health claims. In general, public

[[Page 50700]]

health claims encompass three types of claims: (1) Claims of control of 
specific microorganisms that are pathogenic to man; (2) claims of 
levels of antimicrobial activity that are associated with public health 
protection (e.g., disinfect), even if specific organisms are not named; 
and (3) claims that make non-specific assertions relating to impact on 
public health or safety, e.g., ``provides a germ-free environment.'' 
The use of such terms on a product label is deemed to bring a product 
within the ambit of FIFRA regulation as a public health product.
    Among the last, EPA has specifically included reference to the term 
``sanitary'' as an antimicrobial public health claim. EPA believes that 
this is a logical extension of the term ``sanitize,'' that should be 
considered to bring a product under FIFRA regulation as a public health 
pesticide. EPA regards a product that claims to ``create a sanitary 
environment'' or is intended to achieve ``sanitary'' effects beyond 
itself to be making an assertion of impact on public health. The 
presence of such a claim would clearly constitute a pesticide claim.
    At the same time, EPA recognizes that the term ``sanitary'' may be 
used on a product in the more traditional sense of ``hygienic,'' i.e., 
to convey the fact that the product is clean or has been treated to 
render it free of harmful organisms (for example, ``sanitary'' 
napkins). When used in such a sense, EPA believes that there is no 
intent or claim that the product will have an antimicrobial function 
beyond protection of itself. In the absence of an express claim, EPA 
proposes to consider the claim ``sanitary'' as an implied pesticide 
public health claim, and the product on which it appears as a pesticide 
subject to FIFRA, if: (1) The product composition is similar to other 
products registered under FIFRA that make antimicrobial claims; or (2) 
the product contains a substance that is capable of antimicrobial 
activity at the levels in the product and there is no other functional 
reason for the ingredient to be present in the product. The burden 
would be on the producer of a product that makes a ``sanitary'' claim 
to demonstrate that the claim is not a public health claim. EPA seeks 
comment as to whether its interpretation of ``sanitary'' claims is 
sufficiently clear to unambiguously delineate pesticide products or 
whether it could be overly broad and draw inappropriate products under 
FIFRA.
    Proposed Sec. 156.444 lists examples of specific antimicrobial-
related claims that EPA considers to be unacceptable because they are 
misleading. These are an extension and clarification of existing 
prohibitions against false and misleading statements found in 
Sec. 156.10(a)(5). Again, the listings are intended to be exemplary; 
EPA may determine on a case-by-case basis that a label statement or 
claim is misleading.
    A product that bears a public health claim, but which does not meet 
the performance standard for that claim in subpart W would be 
considered misbranded under FIFRA section 12(a)(1)(E). Registrants have 
been on notice of the unacceptability of these statements from previous 
and current Agency guidelines and policies. On the effective date of 
the final rule, EPA would prohibit these claims from appearing on new 
products. To ensure that all registrants of current produts are 
provided adequate notice and have ample opportunity to evaluate their 
label statements and delete or modify those that are unacceptable, EPA 
proposes to permit registrants a 1 year period in which to modify 
labeling before the Agency would find the products to be misbranded. As 
of a date approximately 1 year after the effective date of the rule, 
the actual date to be specified in the final rule, EPA may take action 
against any product that it determines is misbranded based upon the 
criteria in proposed Sec. 156.444. EPA requests comments on whether a 1 
year period for label compliance is adequate. Based on comments, EPA 
may in the final rule adopt a compliance date of more or less than 1 
year.
    The remainder of subpart W (Secs. 156.445 through 156.458) 
describes the performance standards and acceptable claims that may be 
made for various antimicrobial public health pesticides. Each section 
generally contains the following:
    1. The performance standard for a level of antimicrobial efficacy 
on a specified site (e.g., sanitizing claim on hard surfaces) or, 
alternatively, a description of a use site and the performance 
standards that apply (e.g., fabrics and textiles, air sanitizers).
    2. A reference to the appropriate Guideline for an acceptable test 
protocol. The performance standards are based upon testing in 
accordance with the test methods of the Pesticide Assessment 
Guidelines, Subdivision G, or ``its equivalent.''
    The term ``equivalent'' is defined in Sec. 156.441 to mean a 
protocol or method that accomplishes the purposes of the cited 
Guidelines, and that provides data equal in quality and completeness 
for EPA assessment as that of the cited Guideline. With respect to 
antimicrobial protocols, an equivalent protocol or method must be 
validated by multiple laboratories studies that demonstrate 
equivalency. The term ``Guidelines'' is defined to include both the 
Pesticide Assessment Guidelines, Subdivision G, and the OPPTS 
Harmonized Guidelines. For antimicrobial efficacy testing, these differ 
only in the numbering and formatting of the Guidelines. Ultimately, the 
OPPTS Guidelines are intended to supersede the OPP Guidelines. EPA 
expects the Harmonized Guidelines to be issued before the rule is 
promulgated. Therefore, in proposed subpart W we have included 
references only to those updated Guidelines. A copy of the latest draft 
of the Harmonized Guidelines for Antimicrobial Performance (810 series) 
is included in the public docket. If the Harmonized Guidelines are not 
final and available at the time of promulgation, EPA will substitute 
references to the existing Pesticide Assessment Guidelines in the final 
rule.
    3. A statement of the acceptable claim(s) that may be made on 
labeling of a product that meets the performance standard. Typically, 
explicit terminology or wording is provided, which must be used to 
ensure uniformity of claims. In this respect, Sec. 156.442 would 
clarify that EPA requirements for specific terminology also authorize 
grammatical variations on that terminology, or its use in statements 
and phrases. For example, when EPA specifies that an acceptable claim 
is as a ``tuberculocide,'' a product would be permitted to use the term 
``tuberculocidal'' in a statement or phrase describing the activity of 
the product.
    4. Any restrictions or limitations upon use of the claim. For 
example, proposed Sec. 156.455 states that an air sanitizer must bear a 
statement that accurately describes the limited nature of the 
sanitizing claim.
    5. In some cases, a description of unacceptable claims. Generally, 
both restrictions on claims and unacceptable claims are needed to 
ensure that users, who may have broader expectations of efficacy than 
the product demonstrates and the labeling conveys, are fully informed 
of product limitations. For example, proposed Sec. 156.455 specifies 
that an air sanitizer may not make claims as a sterilant, disinfectant 
or germicide.
    Proposed subpart W does not contain all required use directions for 
antimicrobial public health products. It contains only the specific 
performance standards and closely related restrictions and limitations 
on labeling claims derived from those standards. Adequate use 
directions for achieving expected efficacy require detailed 
instructions that vary depending on the type of product, use site and 
target

[[Page 50701]]

organism, and must be determined on a case-by-case basis. Particularly 
for antimicrobial pesticides, use instructions must reflect very 
specific test parameters keyed to sites of use. For example, the 
presence of soil or moisture on a surface may affect the ability of a 
product to perform, and must be accounted for both in efficacy testing 
and in labeling use directions. These more detailed use instructions 
are contained in Subdivision H, Labeling Requirements for Pesticide Use 
Directions, Antimicrobial Products.

XIII. Other Labeling Revisions

A. Use Dilution Labeling

    FIFRA section 3(c)(9)(D) provides that antimicrobial products that 
are or may be diluted for use may bear a different ``statement of 
caution or protective measures'' for the recommended diluted solution 
than for the concentrate, provided that adequate data have been 
submitted to support the proposed statement and the label provides 
adequate protection for exposure to the diluted solution of the 
pesticide. The Agency has developed policy and procedural guidance 
pertaining to use dilution labeling, and will apply the policy to all 
pesticide products, not just antimicrobial products as required by 
FIFRA. Today's proposal would modify current regulations in part 156 to 
provide specifically for use dilution labeling.
    1. Data requirements. EPA intends to specify in a future part 158 
proposal the data required to support use dilution labeling for 
antimicrobial products.
    The data needed to support use dilution labeling changes consist of 
data on acute toxicity of the diluted product. If a product is diluted 
with water, systemic toxicity (acute oral or dermal toxicity) 
categorization can be supported by calculations from the concentrated 
product. In general, systemic toxicity categories differ by a factor of 
10. Therefore, in most cases, if dilutions are an order of magnitude or 
more, the toxicity category for a particular route of exposure can be 
expected to be the next lower category (Category I is highest). For 
example, if the concentrated product toxicity category is II and the 
product as used is diluted at least 10-fold, the diluted product should 
be in toxicity category III; if it is diluted more than 100-fold, the 
diluted product should be in toxicity category IV.
    On the other hand, label statements triggered by skin or eye 
irritation or dermal sensitization must be supported by new or cited 
studies. Calculations are not acceptable because irritation and 
sensitization effects do not necessarily correlate directly with the 
degree of dilution.
    In some cases, a diluted product may be more irritating than the 
concentrated product. Data may be cited if another registered product 
(such as a ready to use formulation) with a composition similar to the 
diluted product is supported by acceptable data. In all cases in which 
the diluent is other than water, data must be submitted, since diluents 
other than water may themselves be toxic.
    2. Permitted use dilution labeling. EPA proposes to expand its 
current labeling regulations in 40 CFR part 156 to address 
opportunities for use dilution labeling. Currently Sec. 156.10 requires 
that a product be labeled with information on the product as 
distributed and sold. The product that is marketed to users may be a 
concentrate product with directions for use dilution, or may be a 
ready-to-use product requiring no dilution. In many cases, a 
concentrate product as diluted will be substantially similar in 
composition and hazards to a ready-to-use product. It makes sense, 
then, that registrants should be permitted to provide additional 
information on precautions and protective measures for the diluted 
product. At the same time, the addition of statements appropriate for 
the product as diluted should not be allowed to detract from or mislead 
the user as to the hazards of the product in its undiluted form.
    EPA believes that the ``statement of caution or protective 
measures'' referred to in FIFRA section 3(c)(9)(D) includes the first 
aid or practical treatment statement, the human (and animal) 
precautionary statements, and various personal protective equipment 
statements. EPA believes that a ``statement of caution'' does not 
extend to the signal word (DANGER, WARNING, or CAUTION), word POISON 
and skull and crossbones, or child hazard warning (``Keep Out of Reach 
of Children''), which should reflect and alert users to the typically 
higher hazards associated with the concentrate product.
    If the labeling allows a range of dilution, EPA would permit use 
dilution labeling only for the most concentrated dilution. EPA believes 
that there is little value in multiple sets of precautionary statements 
reflecting various levels of use dilution, and that product users would 
find multiple statements cluttering and confusing.
    Because the concentrate product typically presents higher hazards 
than the diluted product, EPA would not permit dilution-based 
statements either to substitute for or modify existing statements for 
the concentrate product. Rather, EPA would permit additional statements 
that augment the information for the concentrate product to appear 
following the concentrate product information. For example, the wording 
in italics could be added to precautionary or first aid statements:

    HAZARDS TO HUMANS. ``Causes substantial but temporary eye 
injury. Do not get in eyes or on clothing. Wear goggles or face 
shield. Wash thoroughly with soap and water after handling. Wash 
contaminated clothing before reuse. After product is diluted, 
goggles or face shield are not required.''
    FIRST AID. ``If on skin: Take off contaminated clothing. Rinse 
skin immediately with plenty of running water. Call a doctor or 
poison control center for further treatment advice. If diluted 
product gets on skin, medical attention is not required.''

    Separate statements could also be used, with appropriate headings 
for ``Concentrate'' and ``Diluted product'' or similar wording.

B. Reorganization of Labeling Regulations

    EPA proposes to reorganize Sec. 156.10(h), which describes labeling 
requirements pertaining to hazard statements, to upgrade its structure. 
EPA believes that this long overdue reorganization is needed to 
accommodate the new use dilution provisions, and to improve the 
readability of the human hazard and precautionary sections of its 
labeling regulations. Ultimately EPA intends to upgrade part 156 
entirely, but at present is doing so only as part of other regulatory 
proposals that affect labeling.
    EPA has already proposed to upgrade the structure of its use 
direction labeling requirements as part of its proposal on Pesticides 
and Ground Water State Management Plans (June 26, 1996; 61 FR 33260). 
That proposal would create subpart G to contain directions for use.
    Today's proposal carries this organizational upgrading one step 
further. EPA proposes to create new subpart D in part 156 (comprising 
Secs. 156.60 through 156.79), and locate in it all human hazard and 
precautionary statements, including physical and chemical hazards. 
Environmental hazard and precautionary statements, currently located in 
Sec. 156.10(h)(2)(ii) would be located in new subpart E.
    In reformatting, EPA has reworded the provisions of current 
Sec. 156.10(h) for clarity, and is proposing several minor changes:
    1. Section 156.64 would eliminate the requirement that a product in 
Toxicity

[[Page 50702]]

Category IV by all routes of exposure bear a signal word. Currently, 
products in Toxicity Categories III and IV bear the same signal word, 
CAUTION. Products in Toxicity Category IV are of minimal toxicity, and 
EPA believes that a signal word is not necessary for effecting the 
purposes for which the product is intended. Indeed, the same signal 
word for two different categories of toxicity may contribute to 
misunderstanding of the hazards of products in both categories.
    In recent research conducted under the Consumer Labeling 
Initiative, users of several types of consumer products tended to 
ascribe a higher level of hazard to products bearing the signal word 
CAUTION than to products bearing no signal word at all. Thus the signal 
word CAUTION on a Category IV product has the potential to be 
misunderstood. Users may consider all products bearing the signal word 
CAUTION as similar in toxicity, even though those in Toxicity Category 
IV pose negligible hazard while those in Category III pose moderate but 
real hazards.
    The hierarchical Toxicity Category scheme is designed to allow 
distinctions to be made among products based on acute toxicity. Signal 
words assigned to the four toxicity categories are intended to allow 
users to make informed choices about the risks of the products they 
purchase. Having the same signal word for two categories runs counter 
to this goal. The hierarchy of product toxicity would be easier to 
convey on labeling if each category were clearly differentiated from 
another. Absent a new signal word to assign to Toxicity Category IV 
products, EPA proposes to eliminate the signal word entirely. The label 
would still be required to bear the child hazard warning.
    2. Section 156.66 would clarify that the child hazard warning, 
``Keep Out of Reach of Children'' is not always appropriate for all 
products, and that EPA may require or permit an alternative wording of 
the statement. This change would codify existing policy.
    3. Section 156.68 would require the heading ``First Aid,'' instead 
of the currently required ``Practical Treatment,'' for the statement 
regarding emergency treatment by a user to mitigate pesticide 
exposures. This change was recommended in the Consumer Labeling 
Initiative Phase I Report (September 30, 1996), in which consumer 
interviews identified label improvements for consumer pesticide and 
non-pesticide products.
    4. Section 156.68 would also require that a first aid statement 
appear on the front panel of the label for each product in Toxicity 
Category I, including for the first time eye and skin irritation 
effects. Currently, the statement is required on the front panel only 
for products in Toxicity Category I based upon systemic effects.
    EPA believes that the current distinction between systemic and 
irritation effects is not justified. The corrosive effects associated 
with exposure to a Toxicity Category I skin or eye irritant are 
potentially irreversible, and EPA believes that information on 
mitigating those effects should be clearly and immediately available to 
the user. Logically, then, first aid measures for skin irritation 
should be as prominently located on the label as those for dermal 
toxicity. Location on the front panel affords the greatest prominence 
to first aid statements.
    5. In creating new subpart E in which to locate environmental 
hazard and precuationary statements, EPA has included in a general 
section (Sec. 156.80) introductory language describing the location and 
type size of environmental hazards statements. Otherwise the 
requirements are the same as those in current Sec. 156.10(h), and 
comment is not requested on this reorganization.

C. Updated Toxicity Categories

    EPA had intended to propose to update its current Toxicity 
Categories for acute hazard labeling. The Toxicity Categories in 
Sec. 156.10(h) were established in 1975 and are no longer current. In 
September 1998, however, the United States agreed in principle with the 
Organization for Economic Cooperation and Development to harmonize 
internationally the classification systems for a number of hazard 
criteria, including acute toxicity. The proposed classification scheme 
differs markedly from EPA's current scheme, both in the number of and 
criteria for acute toxicity categories. Implementation plans for the 
new scheme are intended to be developed by the year 2000.
    In light of the proposed internationally harmonized scheme, EPA has 
decided not to propose to update its toxicity categories. At best, 
updating would be an interim step, which would be superseded in 2 to 3 
years by U.S. implementation of the new scheme, which itself will be a 
major undertaking for the pesticide industry.

XIV. Chemical Sterilants

A. Liquid Chemical Sterilants Excluded by Statute

    FIFRA section 2(u) specifically excludes from the definition of 
``pesticide'' liquid chemical sterilants (and their subordinate 
disinfectant claims) for use on a critical or semi-critical device. 
This change in FIFRA was effective on August 3, 1996, and supersedes 
the interim guidance outlined in PR Notice 94-4 (June 30, 1994). That 
notice pertains to registration procedures for liquid chemical 
sterilant products affected by the June 3, 1993 Memorandum of 
Understanding (MOU), as amended, between EPA and FDA. In accordance 
with the MOU, EPA was preparing a rule to exempt such products from 
FIFRA regulation under section 25(b), which would have yielded 
regulatory jurisdiction solely to FDA. That proposal is no longer 
needed since the jurisdictional change was accomplished statutorily.
    The effect of the exclusion under FIFRA is that such products are 
regulated solely by FDA as ``devices'' as defined in section 201 of the 
FFDCA. EPA has issued a notice to registrants of affected sterilant 
products (PR Notice 98-2, January 15, 1998), informing them of the 
change in regulatory jurisdiction. Today's proposal will codify in new 
Sec. 152.6 the statutory exclusion for liquid chemical sterilants, 
though codification is merely a convenience for the regulated community 
and is not necessary for the exclusion to be effective.
    Codification of the liquid chemical sterilant exclusion does not 
change the interim measures outlined in PR Notice 94-4 for general 
purpose disinfectants, nor does it affect liquid chemical sterilant 
products intended for use on non-medical devices, such as those 
intended for use solely on environmental surfaces, or those which are 
intended for veterinary purposes.

B. Non-liquid Chemical Sterilants Exempted by Regulation

    EPA proposes further to use its authority under FIFRA section 25(b) 
to exempt from FIFRA regulation the following additional antimicrobial 
product types: (1) Non-liquid chemical sterilants for use on critical/
semi-critical devices, except ethylene oxide; (2) non-liquid chemical 
sterilants bearing, in addition, subordinate disinfectant claims for 
use on critical/semi-critical devices.
    FQPA modified the definition of ``pesticide'' in FIFRA section 2(u) 
so as to grant FDA exclusive jurisdiction over

[[Page 50703]]

liquid chemical sterilants for use on critical/semi-critical devices. 
Congress did not, however, address non-liquid chemical sterilants, 
which have similar uses as liquid chemical sterilants. In fact, under 
FFDCA section 510, FDA regulates all chemical sterilants used on all 
medical devices, not just liquid chemical sterilants on critical and 
semi-critical devices. In modifying FIFRA, Congress affirmed that FDA 
jurisdiction under FFDCA section 510 was an adequate means of 
regulating these sterilant products, and that dual oversight with EPA 
was unnecessary to protect the public health.
    FIFRA section 25(b) authorizes EPA, by regulation, to exempt a 
pesticide from any or all provisions of FIFRA if the pesticide is 
adequately regulated by another Federal agency. EPA believes that 
Congress' expression of the adequacy of FDA's approval process for 
liquid chemical sterilants and their subordinate disinfection claims on 
critical/semi-critical devices as a statutory matter is an adequate 
basis for EPA to determine that non-liquid chemical sterilant products 
regulated under the same approval process are adequately regulated by 
another Federal agency.

C. Antimicrobial Products Neither Excluded nor Exempted

    1. Any claims on non-critical medical devices. EPA does not propose 
to exempt sterilants or disinfectant products used on non-critical 
medical devices from FIFRA regulation. Non-critical medical devices 
potentially cover a wide array of items and surfaces, such as blood 
pressure cuffs and bedpans. EPA and FDA currently share jurisdiction 
over products used on non-critical medical devices. However, under its 
1993 MOU with FDA, EPA and FDA agreed to an approach under which FDA 
would grant sole responsibility for products used on non-critical 
medical devices to EPA. FDA has issued a proposal to exempt general 
purpose disinfectant products from the requirement for pre-market 
clearance under FFDCA section 510(k) (63 FR 59917, November 6, 1998).
    2. Any claims on non-medical devices. EPA has sole jurisdiction 
over all claims on non-medical devices. These products are not 
regulated jointly with FDA.
    The combination of the statutory exemption for liquid chemical 
sterilants and the exemptions proposed under FIFRA section 25(b) would 
give FDA sole jurisdiction over all chemical sterilants (except 
ethylene oxide), together with their subordinate level disinfection 
claims for use on all critical and semi-critical medical devices. 
Exempting from FIFRA coverage additional sterilants and uses and 
consolidation of regulatory jurisdiction with FDA will eliminate dual 
regulatory requirements and unnecessary paperwork requirements.
    Table 5 below sets out concisely the status of chemical sterilants 
and other antimicrobial products used on medical devices, and the 
statutory and regulatory transfers that are occurring for liquid and 
non-liquid chemical products. Where the table indicates ``no change'' 
in the last column, the jurisdiction has not changed by statute, and 
EPA is not proposing any regulatory change.

D. Ethylene Oxide

    Ethylene oxide is a gaseous form of sterilant, and thus was not 
transferred to FDA jurisdiction by statute. EPA does not propose to 
exempt the sterilant ethylene oxide because, in contrast to the other 
non-liquid sterilants that would be exempted, ethylene oxide use is not 
limited to medical and hospital use. Ethylene oxide is used as a 
fumigant for foods, particularly for fumigation of whole spices, a use 
regulated by no other Agency except EPA. Thus, even if EPA were to 
exempt the ethylene oxide sterilization use on critical/semi-critical 
devices, EPA might retain significant oversight over ethylene oxide for 
other uses. It makes sense, then, for EPA to retain jurisdiction over 
the sterilant use of ethylene oxide on medical devices.

XV. Nitrogen Stabilizers

A. Nitrogen Stabilizers are Regulated as Pesticides

    FQPA expanded the FIFRA definition of ``pesticide'' to include 
nitrogen stabilizers, but by definition in FIFRA section 2(hh) 
``nitrogen stabilizer'' excludes certain substances. Two named 
substances (dicyandiamide and ammonium thiosulfate) are excluded 
outright. Other substances are excluded

[[Page 50704]]

if they meet the criteria in section 2(hh)(3): They were introduced 
into commercial agronomic use by January 1, 1992, without being 
registered under FIFRA, and thereafter have not made specific claims of 
``prevention or hindering of nitrification, denitrification, ammonia 
volatilization [or] urease production'' (collectively referred to in 
this discussion as ``nitrogen stabilization claims''), except where 
required to do so under State pesticide regulations.
    EPA proposes to add to new Sec. 152.6 those substances that are not 
nitrogen stabilizers by statutory definition and therefore not 
regulated as pesticides when used for nitrogen stabilization purposes. 
All other nitrogen stabilizer products are regulated as pesticides 
under FIFRA. This unit discusses how EPA will determine which nitrogen 
stabilizers it will treat as pesticides.

B. What is a Nitrogen Stabilizer?

    1. Action on soil bacteria. To be a nitrogen stabilizer in the 
first instance, a product must accomplish the purpose of nitrogen 
stabilization through ``action upon soil bacteria.'' Clearly, this 
phrase excludes fertilizer products, which increase soil nitrogen by 
simple addition of nitrogen-containing substances rather than any soil 
bacterial action. However, any product that enhances soil nitrogen 
availability by affecting the soil bacteria is a nitrogen stabilizer, 
regardless of whether it also functions as a fertilizer after action on 
soil bacteria. Such dual products that function both as nitrogen 
stabilizers and fertilizers are regulated under FIFRA if they meet the 
other statutory criteria for nitrogen stabilizers.
    2. Date of introduction into commerce. The first criterion pertains 
to the date of introduction of the product into commerce. Section 2(hh) 
specifies January 1, 1992, as the date before which the product must 
have been in ``commercial agronomic use'' but not registered as a 
pesticide (as well as the date after which no specific claims of 
nitrogen stabilization must have been made in connection with its sale 
and distribution; see below). EPA can verify from its records what 
products were registered before January 1, 1992 (these are nitrogen 
stabilizers that must continue to be registered). EPA interprets 
``commercial agronomic use'' to mean that a product is being 
distributed and sold at the wholesale and retail levels. A product that 
is being distributed only in a limited or restricted way in preparation 
for full marketing is not considered to have achieved commercial 
marketing status.
    3. Specific claims. The second criterion relates to claims made for 
the product. The statute does not define what is meant by a ``specific 
claim of prevention or hindering of the process of nitrification, 
denitrification, ammonia volatilization [or] urease production.'' 
Moreover, there is no explanatory legislative history to guide EPA in 
discerning Congressional intent. Therefore, EPA is interpreting the 
phrase in a common sense manner.
    Nitrification, denitrification, ammonia volatilization, and urease 
production denote specific undesirable actions of soil bacteria with 
the result that nitrogen availability is decreased. Clearly, any 
product that uses these terms on the label is making a ``specific 
claim'' of mitigating that effect. However, other claims which focus 
only on the end result of nitrogen stabilization (increased/prolonged 
availability of nitrogen) are also used on product labels. EPA 
identifies examples of these phrases in proposed Sec. 152.6(b)(4). The 
phrases listed in that section, to the Agency's knowledge, could be 
used to describe only two functions of products--either the fertilizer 
effect of addition of slow-release nitrogen-containing substances, or 
the pesticidal effect on soil bacteria that is nitrogen stabilization 
and has the same end result.
    Although these label claims could theoretically be used to describe 
fertilizers, EPA believes that they are in practice claims of nitrogen 
stabilization rather than fertilizer claims, for the following reasons. 
First, fertilizer products are already excluded from FIFRA regulation 
by EPA's own regulations in Sec. 152.8, and a fertilizer product need 
only be labeled as such (and bear no other pesticide claims) to avoid 
FIFRA regulation. It would make little sense for a fertilizer product 
to bear claims such as ``increases nitrogen uptake'' or ``prolongs 
nitrogen availability'' when a simple declaration as a ``fertilizer'' 
would suffice under FIFRA, and ``fertilizer'' is a description of such 
a product that would be understood by all purchasers. The only other 
plausible use of these ambiguous claims relates to nitrogen stabilizing 
effects on soil bacteria.
    More telling is EPA's experience in evaluating such products. A 
first-hand examination of the labeling and ingredients declaration of a 
product is the most reliable method to determine if products with such 
claims are to be regulated under FIFRA. An examination of this sort is 
similar to the process used for many years to determine the pesticide/
non-pesticide status of plant regulators (pesticide) versus fertilizer 
(non-pesticide) products. In each instance that EPA has examined a 
product bearing a claim such as described in Sec. 152.6(b)(4), EPA has 
determined that the product was, in fact, functioning as a nitrogen 
stabilizer, and that the product composition was consistent with an 
expected nitrogen stabilization purpose rather than, or in addition to, 
a fertilizer purpose.
    Moreover, such an interpretation of indirect claims is in keeping 
with EPA's past and current policies on nitrogen stabilizers. EPA's 
policy has been to treat claims that indicate pesticidal intent as 
pesticide claims that subject the products to regulation under FIFRA. 
Therefore, EPA proposes to treat any claim that states or implies that 
the product will prevent or hinder nitrification, denitrification, 
ammonia volatilization, or urease production as a claim that brings the 
product under the purview of FIFRA as a nitrogen stabilizer. If a 
product functions solely as a fertilizer or a slow- or delayed-release 
fertilizer, is labeled as such with explanatory information on the 
method used to accomplish any delayed- or slow-release action (e.g., by 
encapsulation) and bears no additional claims that appear to be 
nitrogen stabilization claims, it would not be considered a pesticide.
    EPA believes that to do otherwise would create an administrative 
and enforcement inequity that could potentially undermine the intent of 
the statute to the point where it would have little practical effect. 
The purpose of incorporating nitrogen stabilizers into the definition 
of ``pesticide'' in FIFRA section 2(u) is to regulate certain nitrogen 
stabilizers as pesticides. If EPA were to interpret the Act to limit 
the regulatory coverage of nitrogen stabilizers to products that use 
the magic words ``nitrification,'' ``denitrification,'' ``ammonia 
volatilization,'' or ``urease production,'' while ignoring other 
language that makes equivalent but differently phrased claims, a 
product that Congress intended to be regulated could escape FIFRA 
regulation merely by using a ``code phrase'' that conveys the same 
meaning as these terms. Arguably, under such a restrictive 
interpretation, the only nitrogen stabilizers covered by FIFRA might be 
those already registered as of January 1, 1992. EPA believes that 
Congress could not have intended to extend coverage of FIFRA to 
nitrogen stabilizers, only to exclude most or all of those products by 
a mere turn of phrase.
    4. State exclusion. Congress did provide a specific exclusion for 
statements that are required by State

[[Page 50705]]

legislative or regulatory authorities. A product that makes a claim of 
nitrogen stabilization in its labeling or other materials only because 
of a State requirement is not thereby brought under FIFRA regulation. 
Congressional intent is clear: Federal regulatory authority over 
nitrogen stabilizers should not be enlarged by actions of the States. 
Nor does EPA believe that Congress intended that a product that 
triggered Federal regulation by making nitrogen stabilizer claims be 
removed from regulation by subsequent action of a State. Proposed 
Sec. 152.6 therefore makes clear that the State requirement for 
labeling must be a pre-existing one, that is, in place prior to the 
assertion of nitrogen stabilizing claims by the seller or distributor.
    Moreover, a product for which nitrogen stabilization claims are 
made because of a State requirement is nonetheless subject to FIFRA 
regulation if at any time since January 1, 1992, nitrogen stabilization 
claims have been made for the product with respect to its distribution 
and sale in another State that does not have such a requirement. Sale 
or distribution of such a product in any State, including the State 
which imposed the labeling requirement, is subject to the provisions of 
FIFRA.
    The producer of a product who claims eligibility under this 
exclusion would need to maintain sufficient records to clearly 
demonstrate that, as of January 1, 1992, the product was being 
commercially distributed and sold (sales records, for example), and 
that no nitrogen stabilization claims were made after that date (dated 
copies of labeling and advertising, for example). These records are 
maintained by producers as a normal business practice, so no additional 
recordkeeping would be required by this proposal.

XVI. Notification of Registration Changes

A. FQPA Modifications

    EPA proposes to modify its current notification procedures for 
antimicrobial products to conform to those established under FIFRA 
section 3(c)(9). The statutory provisions requiring these changes are 
discussed in Units IV.I. and V.B.
    Prior to FQPA, FIFRA did not provide a notification scheme. In 
1988, EPA implemented a regulatory notification framework (contained in 
Sec. 152.46), under which EPA determines acceptable modifications to 
registration that may be made by notification. The types of acceptable 
notifications are set out in direct notices to registrants, together 
with the procedures for submitting notifications.
    FQPA modified FIFRA with respect to notifications for antimicrobial 
pesticides only, in both substance and procedure. For the first time, 
FIFRA establishes a statutory right for antimicrobial registrants to 
make certain types of changes by notification. Specifically, a 
registrant may modify the labeling of an antimicrobial pesticide 
product to include relevant information on product efficacy, product 
composition, container composition or design or other characteristics, 
that do not relate to any pesticide claim or pesticidal activity. 
Further, FIFRA sets up a procedure for antimicrobial notifications that 
holds both registrants and EPA to a high degree of accountability.
    FIFRA section 3(c)(9) became effective on August 3, 1996; today's 
proposal would codify the procedures of the Act that are already in 
effect. Neither current regulations nor this proposal address the types 
of actions that may be accomplished by notification.
    The notification provisions of the Act apply only to antimicrobial 
products. As a policy matter, EPA could extend both the types of 
notifications and the procedures for notifications to other products. 
After consideration, EPA has decided to allow non-antimicrobial 
registrants to avail themselves of the new types of notifications 
provided by FIFRA section 3(c)(9), but will not propose changes in its 
current procedures for notifications for such products. Although EPA 
believes that the new statutory process for antimicrobials is superior 
in some ways to the existing notification scheme, it is reluctant to 
add an additional procedural layer to a system that appears to work 
well as currently administered.
    Consequently, after the effective date of the rule, EPA would have 
in place two notification schemes (antimicrobials/other pesticide 
products), but would have a unified set of notification actions. After 
the effective date of the rule, antimicrobial registrants would be 
required to follow the notification procedures of Sec. 152.446 only; 
they would not be permitted to follow the current procedures in 
Sec. 152.46. EPA welcomes comment on whether the notification 
procedures for antimicrobials should be adopted across-the-board. If 
persuaded by commenters that there are benefits without undue costs in 
making the procedures for notifications uniform for all products, EPA 
could, in the final rule, adopt the procedures across-the-board. If it 
does so, EPA would simply adopt the provisions of Sec. 152.446 to 
replace those currently in Sec. 152.46.
    Although EPA does not propose to apply the new procedures to all 
products, it believes that the types of notifications permitted by 
FIFRA section 3(c)(9) should be extended to all products rather than 
limiting them to antimicrobials. Doing so does not require that EPA 
modify its regulations in Sec. 152.46, since permitted notifications 
are detailed in direct notices to registrants (PR Notices), a practice 
EPA would continue. Current permitted notifications are specified in PR 
Notice 98-10, issued October 22, 1998.

B. Comparison of Current and New Procedures for Antimicrobial Products

    This unit describes the new procedures for antimicrobial product 
notifications and compares them to the current procedures for all other 
products, which are not proposed for change. The significant 
differences between antimicrobial procedures and current notification 
procedures in Sec. 152.46 are that:
    1. Registrants who submit antimicrobial notifications must wait 60 
days after submission before distributing or selling the modified 
product. Registrants of other products may distribute or sell 
immediately upon submission.
    The new scheme offers an eminently practical solution for the 
uncertainties of compliance and enforcement in the current notification 
process. Under the current scheme, a registrant who ships immediately 
upon notification runs the risk that EPA might thereafter determine the 
notification is improper, and the product would be in violation of 
FIFRA. Because FIFRA section 3(c)(9) prohibits sale and distribution of 
a modified product for 60 days after submission, but requires Agency 
action within 30 days, there will always be some period of time after 
the Agency's decision before an antimicrobial product can be shipped 
legally. There is no possibility (as exists under the current scheme) 
that a registrant will ship an antimicrobial product only to have the 
Agency disapprove the notification. The benefit of certainty is 
somewhat offset by the fact that an antimicrobial registrant must wait 
before shipping. However, EPA proposes in Sec. 152.446 to allow 
shipment at any time after receipt of approval by the Agency (30 days), 
thereby almost halving the 60-day waiting time.
    2. EPA is obligated to disapprove antimicrobial notifications it 
finds unacceptable within 30 days after receipt. Under the current 
process,

[[Page 50706]]

EPA's goal is to make its determination within 30 days, but it is not 
required to do so.
    The new process involves some increase in resources and time on 
EPA's part. Requiring a review and specific disapproval decision within 
30 days of receipt is more demanding than the current scheme which 
lacks a decision deadline. Nonetheless, antimicrobial notifications are 
currently being processed within 30 days, so EPA anticipates little 
pressure on its current antimicrobial program resources to accommodate 
the 30-day decision deadline.
    3. EPA may require substantiating information for an antimicrobial 
notification. Current EPA regulations in Sec. 152.46 do not explicitly 
mention substantiation. EPA proposes that antimicrobial registrants be 
required to retain, and submit upon request, substantiating information 
for each modification. Substantiating information might be required to 
be submitted if the registrant objected to the Agency's disapproval of 
his/her notification. The provision for substantiation of claims for 
antimicrobial products offers EPA greater assurance that the claims are 
in fact accurate, and can be verified objectively or scientifically.
    4. Antimicrobial registrants may formally object to the Agency's 
disapproval of an antimicrobial notification. Current Sec. 152.46 
contains no provision for appeal of an Agency disapproval. The 
availability of an administrative appeals process, if used frequently, 
would increase resource needs to administer the process. However, EPA 
anticipates few appeals since the types of notifications permitted by 
the statute are relatively straightforward decisions for which the 
current notification scheme was designed.

XVII. Conforming and Organizational Changes

A. Changes in Definitions

    EPA is proposing to modify, delete, or add a number of definitions 
to Sec. 152.3. Definitions located in Sec. 152.3 apply to all pesticide 
applications, including antimicrobial applications. The definition of 
``pesticide'' would be deleted because it has become so long and 
complicated in the statute itself that it adds no value to reiterate 
the definition in regulations. The definition of ``active ingredient'' 
would be modified to conform to the change made by FQPA adding nitrogen 
stabilizers. Definitions to be added include the following:
    1. ``Antimicrobial pesticide,'' to allow reference to new subpart 
W. The definition proposed here interprets the statutory definition to 
clarify and give practical meaning to the exclusions from the 
definition for ``wood preservative,'' ``antifouling paint product,'' 
``fungicide for agricultural use'' and ``aquatic herbicide.''
    2. ``Applicant,'' ``registrant'' and ``application for 
registration,'' to create concise terms that cover both new and amended 
registrations.
    3. ``Complete application.'' This definition is being added to 
apply to all pesticide applications because a number of FIFRA 
provisions (not just those for antimicrobial products) depend upon the 
submission of a ``complete application,'' including: (1) the timeframes 
for all ``fast-track'' applications under section 3(c)(3)(B); (2) the 
priority given to review of minor use applications under section 
3(c)(3)(C); and (3) the priority given to so-called ``safer'' 
pesticides under section 3(c)(10). For antimicrobial pesticides, 
Sec. 152.450 contains detailed information on what constitutes a 
complete application.
    4. ``Fast-track application,'' to formalize the term widely used by 
the Agency and the regulated community for applications under FIFRA 
section 3(c)(3).
    5. ``Nitrogen stabilizer,'' to include the statutory term here for 
convenience.

B. Exclusions and Exemptions under FIFRA

    EPA proposes to compile in one location in its regulations the 
various exclusions that have accumulated in FIFRA over the years. 
Exclusions from FIFRA regulation are statutorily designated substances 
that are not to be regulated under FIFRA. Readers should note that 
``exclusions'' do not include exemptions granted under FIFRA section 
25(b), which are pesticides specifically removed from FIFRA regulation 
by Agency action.
    Several exclusions already exist in FIFRA, and are identified in 
current regulations. These include:
    1. Substances used against organisms that are not ``pests'' by 
definition in FIFRA section 2(t).
    2. Substances that are not ``pesticides'' by definition in FIFRA 
section 2(u).
    3. Substances that indirectly are not ``pesticides'' by virtue of 
being excluded from definitions of substances that are pesticides, such 
as ``vitamin-hormone horticultural products,'' which are excluded from 
the definition of ``plant growth regulator'' in FIFRA section 2(v).
    FQPA amended FIFRA to add two additional exclusions for substances 
that are not to be regulated under FIFRA. Because the existing 
exclusions are scattered in FIFRA and have been expanded by FQPA, EPA 
believes it would be useful and convenient to consolidate them in one 
location in its regulations. Accordingly, EPA proposes to create new 
Sec. 152.6 and to include in it both existing and new exclusions.
    Existing exclusions, which have not been altered, include those in 
Sec. 152.8 for pests of living man and animals (human and animal drugs) 
and various soil amendment products, in Sec. 152.20 for human drugs and 
in Sec. 152.25 for vitamin hormone products. New exclusions include 
those for certain liquid chemical sterilants and certain nitrogen 
stabilizer products. EPA believes that proposed Sec. 152.6 contains all 
exclusions provided by statute or existing regulations. If EPA finds 
that it has inadvertently omitted any exclusions provided by statute, 
it will in the final rule add them to Sec. 152.6.

XVIII. Consultations During the Development of this Proposal

    FIFRA section 3(h) requires that EPA, in developing this proposed 
regulation, ``solicit the views from registrants and other affected 
parties to maximize the effectiveness of the rule development 
process.'' EPA has consulted, and maintains an open dialogue with, a 
number of interested parties, both in establishing the streamlined 
antimicrobial program itself and in developing this proposal.

A. Stakeholder Meetings

    Stakeholder meetings were begun shortly after enactment of FQPA--
the first was in November 1996--with a view to engaging the 
antimicrobial industry (which is largely composed of small businesses), 
public health, consumer and environmental groups, in discussions and 
suggestions that could be implemented in the rule. Since then, EPA has 
held a number of open public meetings, approximately every quarter, to 
discuss issues arising from the development of the antimicrobial rule 
and the administration of the antimicrobial registration program. These 
open meetings have been announced in the Federal Register and have been 
attended by registrants, trade associations representing antimicrobial 
producers and users, other Federal agencies, and environmental and 
consumer groups. Information about the meetings and summaries have been 
placed in a public docket (OPP docket control number 00473, located at 
the address given under ADDRESSES). EPA

[[Page 50707]]

intends to conduct further meetings of this nature, and will make 
special efforts to continue and expand the participation of small 
businesses in the dialogue fostered through such meetings.
    To enhance pre-proposal input into the regulatory development 
process, draft language for this proposal was released to the public in 
April 1997, and again in June 1998. Ensuing discussions and comments 
raised a number of issues of concern. Among them were the following:
    1. The opportunity to rebut Agency's conditions of registration. 
When EPA issues a registration, it often does so with conditions 
attached, generally labeling changes. Registrants have not had the 
opportunity to have EPA reconsider conditions they believed were 
onerous or unnecessary. EPA has now modified the proposal to allow 
applicants who disagree with EPA's imposition of labeling changes as a 
condition of registration to submit a rebuttal for consideration.
    2. A shorter review period for resubmissions. Industry was 
concerned that EPA might choose to start its review clock over for 
minor resubmissions to complete an application or respond to Agency 
questions. In response, EPA is proposing a specific new category of 
shortened review period for ``qualifying resubmissions.'' This new 
category would shorten the review period that would otherwise apply by 
30 days for applications with review periods of 120 days or less. EPA 
estimates that approximately 75% of antimicrobial applications each 
year would have review periods of 120 days or less, and would benefit 
from this provision.
    3. How EPA would deal with indications of product lack of efficacy. 
EPA had considered a scheme whereby applicants would agree to accept as 
a condition of registration the imposition of a variety of measures if 
their product was found to be inefficacious after registration. 
Industry was concerned about the vague nature of EPA's proposal, and 
viewed it as potentially costly. As a result, EPA has scrapped this 
scheme, and developed a new one (the sunset provision in Sec. 152.458), 
to respond to their concerns.

B. Workshops

    To complement the stakeholder meetings and extend their approach to 
stakeholder involvement to a larger group of participants, on January 
8-9, 1997, EPA held a highly successful 2-day antimicrobial regulation 
workshop attended by over 300 participants. At a number of plenary 
sessions and small discussion groups, EPA explored with participants 
issues such as improving and streamlining the registration process for 
antimicrobial products, self-certification, harmonization with States 
and the international community, applying for registration, and 
antimicrobial data requirements. A second workshop was held on June 15-
16, 1998, and was attended by an even larger group of stakeholders. A 
major trade association with extensive small business membership was 
fully represented at both workshops. In addition, individual 
representatives of more than 15 small firms attended.

C. Food and Drug Administration

    FQPA modified both FIFRA and FFDCA in ways that either explicitly 
or effectively transferred regulatory authority over a number of 
pesticides between EPA and FDA. As a result, EPA has consulted 
frequently with FDA in preparing this proposal with respect to liquid 
chemical sterilants (see Unit. XIV.) and the transfer of regulatory 
jurisdiction over certain food use antimicrobial residues back to FDA 
(see Unit XI.).

D. Canada

    In the fall of 1996, EPA held discussions with the Pest Management 
Regulatory Agency of Health Canada, which is the Canadian government 
agency responsible for regulation of certain antimicrobial pesticides 
in Canada. These consultations focussed primarily on Canada's system of 
categorizing antimicrobial pesticide types, its administrative 
procedures that EPA might adopt to streamline, simplify and accelerate 
the Agency's procedures, and ways to harmonize data requirements for 
antimicrobial products.
    Although the majority of the discussions targeted administrative 
rather than regulatory changes, EPA has included in this proposal 
expanded application contents (Sec. 152.450) that will, in addition to 
assisting U.S. regulators of antimicrobial pesticides, foster 
harmonization of application reviews between Canada and the U.S. For 
example, the requirement that an applicant supply copies of available 
data reviews conducted by other countries (such as Canada) will 
contribute to more efficient regulation of antimicrobial products. In 
addition, EPA's rigorous application of completeness criteria as a 
resource management tool mirrors that of Canada.

XIX. Table of Affected Sections

    Because today's proposal covers myriad and diverse topics that 
affect several portions of the Code of Federal Regulations, EPA has 
summarized in Table 6 below all parts and sections for which additions 
or changes are being proposed today.

XX. Statutory Review Requirements

    In accordance with FIFRA section 25(a), this proposal was submitted 
to the FIFRA Scientific Advisory Panel, the Secretary of Agriculture 
(USDA), the Secretary of Health and Human Services (HHS), and 
appropriate Congressional Committees. The Scientific Advisory Panel 
waived its review of this proposal.

A. USDA Comments

    1. USDA suggested that the document include a discussion of the 
issues surrounding microbial pest resistance.
Response: While there is evidence that microorganisms develop 
resistance to antibiotics, EPA is not aware of evidence that 
microorganisms are developing resistance to antimicrobial pesticides. 
Microorganisms respond to biocidal agents, and differ markedly in 
susceptibility and resistance responses to agents such as disinfectants 
and antiseptics. Bacterial resistance to biocides is usually considered 
to be of two types: (1) Intrinsic (a natural property of an organism); 
or (2) acquired (by genetic mutation or physiological adaptation). The 
mechanisms of susceptibility and resistance to biocides and techniques 
that would enhance or reduce susceptibility/resistance are not well 
understood and would require further research.
    EPA expects that it would become aware of developing microbial pest 
resistance in public health products either through registrant 
reporting of lack of efficacy under FIFRA section 6(a)(2) or through 
the 5-year retesting program. A public health product that failed to 
demonstrate efficacy at the 5-year mark would be removed from the 
marketplace by automatic expiration of the registration.
    2. USDA suggested that EPA clarify in the proposal the status of 
agricultural microorganisms other than fungi, for example, nematodes.
Response: EPA has revised Unit VI.C. of the preamble and the definition 
of ``antimicrobial pesticide'' in Sec. 152.3 to clarify that an 
agricultural fungicide is one applied to crops or plants pre-harvest. 
It should be noted that nematodes are not considered microorganisms, 
but invertebrates, and thus would not be included in the definition of 
antimicrobial pesticide in any case.
    3. USDA suggested that EPA standardize the review processes and 
times for wood preservatives and antifoulant paints.
Response: FIFRA section 2(mm) specifically excludes wood preservatives 
and antifoulant paints from the definition of ``antimicrobial 
pesticide,'' and thus, with only limited exceptions, also excludes such 
products from the application review periods that this proposal would 
establish for antimicrobial pesticides. Therefore, EPA is not proposing 
to include wood preservatives and antifoulant paints within the scope 
of this regulation and its review periods. Unit VIII.H.4. contains a 
full explanation of when the review periods apply to certain wood 
preservative products. The review periods discussed in that unit, 
however, do not extend to antifoulant paints.
    As a practical matter, the review processes for all wood 
preservatives and antifoulant paints are the same regardless of where 
within the EPA organization they originate. The data requirements and 
risk assessments for such products are the same and depend on the 
chemical and the potential risks from its use, regardless of whether 
there is a statutory review period.

B. HHS Comments

    HHS provided informal comments on the draft, many of which were 
questions, clarifications, or corrections to the proposal. EPA has made 
changes to the draft proposal in many instances based upon their 
suggestions. A brief summary of their substantive comments follows.
    1. HHS wanted to know the relationship between ``antimicrobial 
pesticides'' and ``public health pesticides'' and whether they were 
treated differently in the proposal.
Response: Both terms are defined in FIFRA. ``Antimicrobial pesticide'' 
is defined in FIFRA section 2(mm) to include, among other things, 
products intended to ``disinfect, sanitize, reduce, or mitigate growth 
or development of microbiological organisms.'' ``Public health 
pesticide'' is defined in FIFRA section 2(nn) to include products for 
the ``. . . prevention or mitigation of viruses, bacteria, or other 
microorganisms . . . that pose a threat to public health.'' An 
antimicrobial pesticide may be a public health pesticide if it is 
intended to destroy or mitigate microoganisms that pose a threat to 
public health.
    However, there is a single standard for registrability of a 
pesticide in FIFRA section 3(c)(5), namely that the pesticide itself, 
or in its intended use, not cause ``unreasonable adverse effects'' on 
man or the environment, taking into account the economic, social, and 
environmental costs and benefits of the use of the pesticide. This is a 
risk/benefit balancing provision. Of significance, though, is that EPA 
is specifically directed to take into account the health risks posed by 
the disease vectors controlled by a public health pesticide when 
weighing its risks and benefits. Under FIFRA section 6(b)(2), when EPA 
is contemplating action against a public health pesticide based on 
risk, HHS should provide information on use and benefits to the Agency 
to inform its risk/benefit decision.
    2. HHS asked about the scope of the proposed rule in relation to 
HHS activities under FFDCA section 409. HHS noted the statutory 
definition of ``antimicrobial pesticide'' in FIFRA,

[[Page 50709]]

which excludes pesticides that require a clearance under either FFDCA 
secton 408 or 409. HHS also noted that ARTCA grants jurisdiction over 
many antimicrobial pesticide residues in food to FDA (discussed in Unit 
XI.), but it still requires registration of the pesticides under FIFRA.
Response: The definition of ``antimicrobial pesticide'' applies only to 
registration activities under FIFRA; it does not affect activities 
related to any FFDCA section 409 food additive regulation. EPA has no 
jurisdiction under section 409. Any action affecting the registration 
of an antimicrobial pesticide under FIFRA, such as cancellation or 
expiration under the ``sunset provision,'' would not necessarily 
require that FDA revise or revoke any food additive regulations 
associated with that pesticide.
    A similar situation could arise if EPA has established a tolerance 
or exemption under section 408 for a pesticide whose registration has 
expired under the sunset provision. As noted in Unit IX, the sunset 
provision is intended to ensure efficacy of public health products, not 
to determine whether the tolerance fails to meet the ``reasonable 
certainty of no harm'' standard of FFDCA. It is unlikely that the 
cancellation or expiration of any single product registration would 
trigger action to revoke the tolerance because there likely would 
remain other products on the market for the same use that are supported 
by the same tolerance or food additive regulation.
    That said, EPA proposes to include all antimicrobial products in 
the scope of its proposed regulation. Unit VIII.B contains a full 
explanation of the applicability of subpart W. Under Sec. 152.441, 
subpart W applies not only to ``antimicrobial pesticides,'' but also to 
antimicrobial products whose registration requires a clearance under 
FFDCA section 408 or 409. Because the proposed rule affects only FIFRA 
actions, however, the difference in coverage of the statutory term 
``antimicrobial pesticide'' and the broader coverage of the proposed 
rule is not expected to affect HHS activities under FFDCA over those 
same pesticides.
    3. HHS commented that EPA's proposal would expand the scope of FDA 
authority over chemical sterilants beyond that agreed to by EPA and 
FDA.
Response: EPA has revised the proposal to align its provisions with 
FDA's understanding of our respective responsibilities (see Unit XIV.).
    4. HHS comments suggested several areas where increased EPA/FDA 
consultation was desirable or necessary, for example, enforcement of 
labeling claims for products subject to both EPA and FDA jurisdiction.
Response: EPA and HHS are in the process of developing a Memorandum of 
Understanding (MOU) that would address responsibilities and 
consultations in a number of areas. The MOU is expected to establish a 
consultative process between the Agencies that will facilitate 
information exchange and resolution of issues. EPA expects that the 
consultations undertaken under the MOU will serve the various purposes 
noted by FDA. Currently EPA consults informally with counterparts in 
the FDA, the Centers for Disease Control, and other HHS offices on 
issues of joint authority and mutual interest.
    5. HHS requested that EPA clarify the status under the Freedom of 
Information Act (FOIA) of data and/or data reviews provided to other 
agencies if the applicant authorizes EPA to share such data.
Response: The status of data provided to another agency under a 
registrant authorization would not change under FOIA because of the 
data sharing. A request to HHS for the release of such data would be 
treated the same under FOIA as a request to EPA.
    6. HHS had a number of comments related to the efficacy performance 
standards (part 156, subpart W).
    a. Virucidal claims. HHS suggested that EPA consider selecting 
representative viruses with differing intrinsic resistance to 
antimicrobial chemicals and use those as benchmark viruses for test 
purposes in support of a general virucidal claim.
Response: Currently, EPA requires that each specific virus intended to 
be claimed on the label be tested, and identified on the labeling. EPA 
takes the position that there is no known data base that assures that 
all viruses have the same susceptibility or resistance responses to 
antimicrobial agents, or that allows across-the-board extrapolation of 
results. Nonetheless, EPA has funded a 3-year research project on the 
use of surrogate viruses. The results from this study are currently 
under review.
    b. Efficacy terminology. HHS noted that there are differences in 
terminology between EPA and HHS performance measures. HHS considers a 
laboratory test demonstrating product efficacy to be a test of a 
chemical's ``potency'' and not its ``efficacy.'' HHS believes that 
``efficacy'' is demonstrated only in the ability of an antimicrobial 
agent to reduce or prevent transmission of disease.
Response: EPA acknowledges these differences. In the case of 
antimicrobial pesticides, EPA uses the term ``efficacy'' to refer to 
laboratory testing that demonstrates ``presumptive'' efficacy of a 
product in reducing microbial populations on environmental surfaces. 
FIFRA specifically excludes as pests microorganisms in or on living man 
or other living animals (as opposed to microorganisms on surfaces to 
which man might be exposed). Effectiveness testing that would 
demonstrate performance of an antimicrobial pesticide against 
microorganisms in man and that would meet HHS' definition concerning 
actual reduction or prevention of disease is not within EPA's purview.
    Based upon the laboratory tests that demonstrate efficacy for FIFRA 
purposes, EPA permits label claims only to the extent that the product 
reduces or eliminates target organisms under standard laboratory 
conditions or carefully defined simulated use protocols. Because EPA 
does not require or evaluate data on disease-related claims, 
antimicrobial pesticide products are not permitted to bear claims 
concerning reduction in transmission or prevention of disease, though 
they may claim the ability to reduce precursor microorganisms.
    c. ``Sanitization'' claims. HHS requested clarification of the 
scope of the Agency's policy on ``sanitary'' and ``sanitize'' as 
pesticide public health claims. HHS noted that a product that 
``sanitizes'' food equipment would not be an ``antimicrobial 
pesticide'' under FIFRA section 2(mm) because such use would be a food 
use requiring a tolerance or exemption under section 408. They 
requested clarificaiton as to whether such a sanitizer would be subject 
to subpart W labeling requirements, and whether it would be a public 
health pesticide.
Response: Yes. A pesticide that sanitizes food equipment would be a 
public health pesticide because sanitization is a claim of a specific 
level of antimicrobial activity against microorganisms associated with 
public health protection. It would therefore be subject to the labeling 
requirements of proposed subpart W of part 156. As noted earlier, the 
definition of ``antimicrobial pesticide'' in the proposal is broader 
than that in the statute. EPA has revised Sec. 156.440 to clearly state 
that the applicability of part 156, subpart W, corresponds to that in 
part 152, subpart W, which would encompass food use sanitizers.

XXI. Regulatory Assessment Requirements

A. Executive Order 12866

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), 
entitled Regulatory Planning and Review, this action is not a 
``significant regulatory action'' subject to review by the Office of 
Management and Budget (OMB). This proposal is not expected to have 
significant impacts on antimicrobial pesticide producers and would have 
no impacts on any other sector of the economy. Moreover, a number of 
its provisions, including exemptions for various antimicrobial 
sterilants, reduction in duplicative regulation with FDA, and mandatory 
review periods for antimicrobial applications, are expected to decrease 
costs and burdens currently associated with the registration of 
antimicrobial pesticide products.
    EPA has prepared an economic analysis of the potential costs 
associated with this proposed action, which is contained in a document 
entitled Regulatory Impact Analysis of the Proposed Antimicrobial 
Pesticide Rules. This document is available in the public record for 
this action and is summarized in this unit.
    The only costs anticipated as a result of this action are the costs 
of compliance with the ``sunset provision.'' Under this provision, 
proposed in Sec. 152.458, registration of a public health antimicrobial 
pesticide would expire every 5 years unless the registrant certifies, 
based upon efficacy and composition studies conducted within the year 
prior to expiration, that the product continues to meet the standards 
for registration. The studies required are an analysis of the product 
composition to confirm certified limits of the ingredients, and 
efficacy studies for each public health claim on the product labeling.
    The costs of the analysis and certified limits determination are 
estimated to be approximately $6,100 per product. The average cost of 
the efficacy studies is estimated to be just under $25,500 per product, 
based upon an average of six efficacy tests per product. The average 
annualized testing cost per product is $5,620. However, while all 
public health products would be subject to product analysis testing, 
only about 61% of products would be subject to efficacy testing, 
because some products can rely on testing developed for substantially 
similar products. Accordingly the adjusted annualized testing cost for 
products expected to actually have to conduct the testing is $3,897. 
The total annualized cost for both existing and new products is 
estimated to be $12.3 million.
    In neither case are these costs expected to result in additional 
capital costs to applicants because such studies are currently required 
of applicants for registration, whether conducted by the applicants 
themselves, or, more typically, contracted for with outside 
laboratories.
    The assumptions used in the analysis result in an overstatement of 
the costs of the rule, for the following reasons:
    1. The analysis assumes that the testing requirement imposes costs 
effective immediately upon promulgation in 1999. However, actual costs 
will be imposed only as products are submitted for new or amended 
registration or reregistration over the next several years, on a 
schedule that EPA cannot predict. For a product first registered, 
amended or reregistered in 1999, the testing cost would be imposed only 
in the fourth year of registration (2003).
    2. The analysis assumed that no firms were already complying with 
the sunset provisions that would be imposed. Based upon consultation 
with a limited number of small businesses, EPA estimates that 
approximately 11% of firms currently conduct testing that would comply 
fully, and others conduct testing that would comply partially. It is 
likely that a higher percentage of large firms would already be fully 
or partially complying.
    All other provisions of this proposal would reduce the costs of 
compliance with FIFRA for producers of antimicrobial pesticides. 
Provisions that reduce costs include increased opportunities for 
notification instead of amendment of registration, elimination of dual 
jurisdiction with FDA, exemption of certain antimicrobial products from 
FIFRA regulation, more precise and clearer application and labeling 
information, and mandatory review periods for antimicrobial 
applications that are shorter than historical review times.

B. Regulatory Flexibility Act

    Under section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 
601 et seq.), the Agency hereby certifies that this proposed action, if 
promulgated as proposed, action will not have a significant economic 
impact on a substantial number of small entities. The factual basis for 
this determination is contained in the Economic Analysis referenced in 
Unit XXI.A., and summarized in this unit. The only provisions in this 
proposal that would impose costs on any business, including small 
businesses, are the sunset provisions, discussed in Unit XXI.A.
    For the purpose of analyzing potential impacts on small entities, 
EPA used the RFA definition of small entities in section 601(6) of the 
RFA. Under this section, small entities include small governments, 
small nonprofit organizations, and small businesses. Because EPA does 
not believe that governments or nonprofit organizations are likely to 
be burdened by this proposed rule, EPA's analysis presents only the 
estimated potential impacts on small businesses.
    Table 7 below summarizes the results of EPA's analysis.

                                                          Table 7.--Impacts on Small Businesses

1 Calculated as a percentage of Annual Sales Revenue.
2 Calculated on the basis of 848 small businesses registering antimicrobial products.
3 The totals are cumulative, that is, the >3% and >10% values are included in the >1% totals.

    EPA believes that all costs and burdens of this proposed rule are 
attributable to the ``sunset provision'' requiring periodic efficacy 
retesting and analysis of products after registration. In preparing for 
today's proposal, EPA conducted discussions with all segments of the 
industry, including small business (see discussion in Unit XVIII.A.), 
and we have adopted many of their suggestions to minimize burden. We 
invite comment on whether there are additional accommodations specific 
to the sunset provision that the Agency

[[Page 50711]]

should consider to further reduce the burden on small businesses.
    Based on consultation with the regulated community, EPA believes 
that all other provisions would be both beneficial and cost-efficient 
to all segments of the antimicrobial industry, including small 
business. Specifically, EPA believes that there are overall reduced 
paperwork burdens and costs associated with increased notifications and 
exemptions from FIFRA; increased flexibility for applicants due to the 
many opportunities for informal consultations, rebuttals, and 
negotiations; greater clarity in the requirements for antimicrobial 
registration and product labeling; and cost savings for individual 
firms in obtaining registrations within the shortened review periods, 
allowing earlier entry into the market. We invite comment on whether 
there are additional accommodations we should consider that might 
further facilitate the registration process for small businesses.
    Are there costs or burdens, efficiencies or savings attributable to 
this proposed rule that you believe have not been adequately identified 
and addressed? What are they and how great are these burdens or 
efficiencies? If you have a proposal for additional accommmodations to 
small business, please explain what you are proposing and provide 
information on costs or benefits of your approach.
    For a discussion of the Agency's outreach to the antimicrobial 
industry, including small businesses, and changes to this proposal 
resulting from input by industry, including small businesses, refer to 
Unit XVIII.A.
    Since the Agency's economic analysis for this proposal estimates 
that 83% of all antimicrobial registrants are small businesses, EPA is 
particularly interested in receiving comment from small businesses as 
to the benefits, costs, and impacts of this proposed rule.
    Information relating to EPA's certification is provided upon 
request to the Chief Counsel for Advocacy of the Small Business 
Administration, and is included in the docket for this rulemaking. Any 
comments regarding the economic impacts that this proposed regulatory 
action may impose on small entities should be submitted to the Agency 
at the address listed in ADDRESSES.

C. Unfunded Mandates Reform Act

    Under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) 
(Public Law 104-4), EPA has determined that this action does not 
contain a Federal mandate that may result in expenditures of $100 
million or more for State, local, and tribal governments, in the 
aggregate, or the private sector in any 1 year. The costs associated 
with this action are described in the Executive Order 12866 section 
above. In addition, EPA has determined that the proposed rule will not 
significantly or uniquely affect small governments and does not contain 
a significant Federal intergovermental mandate. As such, this action is 
not subject to sections 202, 203, 204 or 205 of UMRA.

D. Consultation and Coordination with Indian Tribal Governments

    Under Executive Order 13084, entitled Consultation and Coordination 
with Indian Tribal Governments (63 FR 27655, May 19, 1998), EPA may not 
issue a regulation that is not required by statute, that significantly 
or uniquely affects the communities of Indian tribal governments, and 
that imposes substantial direct compliance costs on those communities, 
unless the Federal government provides the funds necessary to pay the 
direct compliance costs incurred by the tribal governments. If the 
mandate is unfunded, EPA must provide to OMB, in a separately 
identified section of the preamble to the rule, a description of the 
extent of EPA's prior consultation with representatives of affected 
tribal governments, a summary of the nature of their concerns, and a 
statement supporting the need to issue the regulation. In addition, 
Executive Order 13084 requires EPA to develop an effective process 
permitting elected and other representatives of Indian tribal 
governments ``to provide meaningful and timely input in the development 
of regulatory policies on matters that significantly or uniquely affect 
their communities.''
    Tribal governments would not be subject to the requirements of 
today's proposal. In addition, for the most part, today's proposal 
implements requirements specifically set forth by the Congress in FIFRA 
without the exercise of any discretion by EPA. The remainder of today's 
proposal does not significantly or uniquely affect the communities of 
Indian tribal governments. Accordingly, the requirements of section 
3(b) of Executive Order 13084 do not apply to this proposal.

E. Enhancing Intergovernmental Partnerships

    Under Executive Order 12875, entitled Enhancing the 
Intergovernmental Partnership (58 FR 58093, October 28, 1993), EPA may 
not issue a regulation that is not required by statute and that creates 
a mandate upon a State, local or tribal government, unless the Federal 
government provides the funds necessary to pay the direct compliance 
costs incurred by those governments. If the mandate is unfunded, EPA 
must provide to OMB a description of the extent of EPA's prior 
consultation with representatives of affected State, local and tribal 
governments, the nature of their concerns, copies of any written 
communications from the governments, and a statement supporting the 
need to issue the regulation. In addition, Executive Order 12875 
requires EPA to develop an effective process permitting elected 
officials and other representatives of State, local and tribal 
governments ``to provide meaningful and timely input in the development 
of regulatory proposals containing significant unfunded mandates.''
    For the most part, today's proposal implements requirements 
specifically set forth by the Congress in FIFRA without the exercise of 
any discretion by EPA. The remainder of today's proposal would not 
impose any enforceable duties on State, local or tribal governments. 
Accordingly, the requirements of section 1(a) of Executive Order 12875 
do not apply to this proposal.

F. Federalism Review

    The Agency has determined that this action will not have a 
substantial direct effect on States, the relationship between the 
Federal government and States, the distribution in power between the 
Federal government and States, the responsibilities among the levels of 
government, or involve the potential pre-emption of State law as 
described by Executive Order 12612, entitled Federalism (52 FR 41685, 
October 30, 1987).

G. Children's Health Protection

    This proposed rule is not subject to Executive Order 13045, 
entitled Protection of Children from Environmental Health Risks and 
Safety Risks (62 FR 19885, April 23, 1997) because this action is not 
an economically significant regulatory action as defined by Executive 
Order 12866 (see section A. of this unit). This proposed rule is 
procedural in nature and does not involve decisions on environmental 
health risks or safety risks that may disproportionately affect 
children.

[[Page 50712]]

H. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (NTTAA), 15 U.S.C. 272 note) directs EPA to use voluntary 
consensus standards in its regulatory activities unless to do so would 
be inconsistent with applicable law or impractical. Voluntary consensus 
standards are technical standards (e.g., materials specifications, test 
methods, sampling procedures, etc.) that are developed or adopted by 
voluntary consensus standards bodies. This proposed regulation does not 
involve technical standards that would require Agency consideration of 
voluntary consensus standards. EPA requests comment on this conclusion.

I. Environmental Justice

    This proposed rule does not directly affect minority populations or 
low-income groups. Therefore, under Executive Order 12898, entitled 
Federal Actions to Address Environmental Justice in Minority 
Populations and Low-Income Populations (59 FR 7629, February 16, 1994), 
the Agency has not considered environmental justice-related issues with 
regard to the potential impacts of this action on the environmental and 
health conditions in low-income and minority communities.

J. Paperwork Reduction Act

    The information collection requirements contained in this proposed 
rule have been submitted to OMB under the Paperwork Reduction Act 
(PRA), 44 U.S.C. 3501 et seq., and in accordance with the procedures at 
5 CFR 1320.11. An Information Collection Request (ICR) document has 
been prepared by EPA (EPA ICR No. 277.12) and a copy may be obtained 
from Sandy Farmer, OP Regulatory Information Division; Environmental 
Protection Agency (2137); 401 M St., SW.; Washington, DC 20460, by 
calling (202) 260-2740, or electronically by sending an e-mail message 
to: [email protected]. An electronic copy has also been posted with 
the Federal Register notice on EPA's homepage with other information 
related to this action and included in the public version of the 
official record for the proposed rule. An Agency may not conduct or 
sponsor, and a person is not required to respond to a collection of 
information subject to OMB approval under the PRA unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations, after initial publication in the Federal Register, are 
maintained in a list at 40 CFR part 9.
    The annual public burden for this collection of information, which 
will be submitted for approval as an addendum to the existing ICR 
approved under OMB Control No. 2070-0060, is estimated to range from 1 
hour to 10.4 hours per response, depending upon the activity. The cost 
is estimated to range from $71.00 to $755.00 per response, again 
depending on the particular response. The actual number of respondents 
and the frequency of response are not known because many of the 
responses are at the discretion of the respondent. However, based upon 
EPA estimates, the revisions in the proposed rule would increase the 
current burden by an estimated 6,395 hours and $466,740.
    Under 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 includes the time needed to review instructions; 
processing and maintaining information, and disclosing and providing 
information; search data sources; complete and review the collection of 
information; and transmit or otherwise disclose the information.
    Comments are requested on the Agency's need for this information, 
the accuracy of the provided burden estimates, and any suggested 
methods for minimizing respondent burden, including through the use of 
automated collection techniques. Send comments on the ICR to the EPA at 
the address provided above, with a copy to the Office of Information 
and Regulatory Affairs, Office of Management and Budget, 725 17th St., 
NW., Washington, DC 20503, marked ``Attention: Desk Officer for EPA.'' 
Please remember to include the ICR number in any correspondence. The 
final rule will respond to any comments on the information collection 
requirements contained in this proposal.

List of Subjects in 40 CFR Parts 152 and 156

    Environmental protection, Administrative practice and procedure, 
Labeling, Occupational safety and health, Pesticides and pests, 
Reporting and recordkeeping requirements.

    Dated: September 7, 1999.
Carol M. Browner,
Administrator.
    Therefore, it is proposed that 40 CFR chapter I, subchapter E be 
amended as follows:

PART 152--[AMENDED]

    1. In part 152:
    a. The authority citation for part 152 continues to read as 
follows:

    Authority: 7 U.S.C. 136-136y.

    b. Section 152.1 is revised to read as follows:


Sec. 152.1   Scope.

    Part 152 sets out procedures, requirements, and criteria for the 
registration of pesticide products under FIFRA section 3, and for 
associated regulatory activities affecting registration.
    (a) Subparts A, B, C, E, F, G, I, and U of this part apply to all 
products except antimicrobial products.
    (b) Subparts A, B, E, F, G, I, U, and W of this part apply to 
antimicrobial products.
    c. Section 152.3 is amended by removing the paragraph designations 
for the existing definitions, removing the definition for 
``pesticide,'' revising the definitions for ``active ingredient''and 
``applicant'', and adding alphabetically new definitions to read as 
follows:


Sec. 152.3   Definitions.

      *    *    *    *    *
    Active ingredient means any substance (or group of structurally 
similar substances if specified by the Agency) in a pesticide product 
that will prevent, destroy, repel, or mitigate any pest, or that 
functions as a plant regulator, desiccant, defoliant, or nitrogen 
stabilizer.
      *    *    *    *    *
    Antimicrobial pesticide means a pesticide product that:
    (1) Is intended to have pesticide activity against microbiological 
pests, or to protect inanimate articles, substances, industrial 
processes or systems from deterioration, fouling, or contamination 
caused by bacterial, viral, fungal, protozoan, algal or slime pests; 
and
    (2) In the intended use is exempt from or not subject to the 
requirement for a tolerance under FFDCA section 408 or a food additive 
regulation under FFDCA section 409.
    (3) The term does not include any of the following:
    (i) A wood preservative or antifouling paint that makes any non-
antimicrobial pesticidal claim (such as insecticidal), regardless of 
whether it also makes an antimicrobial claim. A wood preservative that 
makes only an antimicrobial claim is an antimicrobial pesticide.
    (ii) A fungicide for agricultural use. A fungicide is considered to 
be for agricultural use if it is intended to be applied to soil or to 
growing plants before harvest. A fungicide intended for post-harvest 
use is not considered to be

[[Page 50713]]

for agricultural use. ``Fungus,'' as defined in FIFRA, includes rust, 
smut, mildew, mold, yeast, and bacteria.
    (iii) A herbicide for aquatic use. A herbicide is considered to be 
for aquatic use if it is intended to be applied directly to natural or 
environmental bodies of water (such as lakes, ponds, or streams) or to 
terrestrial areas bordering environmental bodies of water for control 
of algae or weeds. A pesticide solely for control of algae in non-
environmental waters (such as swimming pools or industrial water 
systems) is considered to be an antimicrobial pesticide and not an 
aquatic herbicide.
      *    *    *    *    *
    Applicant means a person applying for a new registration, or a 
registrant applying for an amended registration or submitting a 
notification.
    Application for registration means an application for new or 
amended registration.
      *    *    *    *    *
    Complete application means an application for registration that 
contains all data, forms, and information required by EPA to be 
submitted with the application, and that will allow EPA to initiate 
review, notwithstanding that EPA may determine that additional 
information is required to approve the application. To be a complete 
application, each required item, and the application as a whole, must 
be determined by EPA to be complete, accurate, readable, and submitted 
in the format and number of copies required by the Agency.
      *    *    *    *    *
    Fast-track application means an application under FIFRA section 
3(c)(3).
    FFDCA means the Federal Food, Drug, and Cosmetic Act, as amended 
(21 U.S.C 201 et seq.).
      *    *    *    *    *
    Nitrogen stabilizer means any substance or mixture of substances 
intended for preventing or hindering the process of nitrification, 
denitrification, ammonia volatilization or urease production through 
action upon soil bacteria, except that the term does not include:
    (1) Dicyandiamide and ammonium thiosulfate; or
    (2) Any substance or mixture of substances in commercial agronomic 
use before January 1, 1992, that was not registered before January 1, 
1992, and for which the seller or distributor has made no specific 
claims of preventing or hindering the process of nitrification, 
denitrification, ammonium volatilization or urease production after 
January 1, 1992.
    Registrant means a person to whom a registration has been issued. 
In this part 152, if the term ``applicant'' and ``registrant'' would 
both apply, the term ``applicant'' is used.
      *    *    *    *    *
    d. By adding new Sec. 152.6 to read as follows:


Sec. 152.6   Substances excluded from regulation by FIFRA.

    Products and substances listed in this section are excluded from 
FIFRA regulation if they meet the specified conditions or criteria.
    (a) Liquid chemical sterilants. A liquid chemical sterilant product 
is not a pesticide under FIFRA section 2(u) if it meets all of the 
following criteria. Excluded products are regulated by the Food and 
Drug Administration. Products excluded are those meeting all of the 
following criteria:
    (1) Composition. The product must be in liquid form as sold or 
distributed. Pressurized gases or products in dry or semi-solid form 
are not excluded by this provision. Ethylene oxide products are not 
liquid products and are not exempt under this exclusion.
    (2) Claims. The product must bear a sterilant claim, or a sterilant 
plus subordinate level disinfection claim. Products that bear 
antimicrobial claims solely at a level less than ``sterilant'' are not 
excluded and are jointly regulated by EPA and FDA. ``Sterilant'' is 
defined in Sec. 156.441 of this chapter.
    (3) Use site. The product must be intended and labeled only for use 
on ``critical or semi-critical devices.'' A ``critical device'' is any 
device which is introduced directly into the human body, either into or 
in contact with the bloodstream or normally sterile areas of the body. 
A ``semi-critical device'' is any device which contacts intact mucous 
membranes but which does not ordinarily penetrate the blood barrier or 
otherwise enter normally sterile areas of the body. Liquid chemical 
sterilants that bear claims solely for non-critical medical devices are 
jointly regulated by EPA and FDA. Liquid chemical sterilants bearing 
claims solely for use sites that are not medical devices, such as 
veterinary equipment, are not excluded and are regulated by EPA.
    (b) Nitrogen stabilizers. A nitrogen stabilizer is excluded from 
regulation under FIFRA if it is a substance (or mixture of substances) 
meeting all of the following criteria:
    (1) The substance prevents or hinders the process of nitrification, 
denitrification, ammonia volatilization, or urease production through 
action affecting soil bacteria and is distributed and sold solely for 
those purposes and no other pesticidal purposes.
    (2) The substance was in ``commercial agronomic use'' in the United 
States before January 1, 1992. EPA considers a substance to be in 
commercial agronomic use if it is available for sale or distribution to 
users for direct agronomic benefit, as opposed to limited research, 
experimental, or demonstration use.
    (3) The substance was not registered under FIFRA before January 1, 
1992.
    (4) Since January 1, 1992, the distributor or seller has made no 
claim that the product prevents or hinders the process of 
nitrification, denitrification, ammonia volatilization, or urease 
production. EPA considers any of the following claims (or their 
equivalents) to be a claim that the product prevents or hinders 
nitrification, denitrification, ammonia volatilization, or urease 
production:
    (i) Improves crop utilization of applied nitrogen.
    (ii) Reduces leaching of applied nitrogen or reduces ground water 
nitrogen contamination.
    (iii) Prevents nitrogen loss.
    (iv) Prolongs availability of nitrogen.
    (v) Increases nitrogen uptake, availability, usage, or efficiency.
    (5) A product will be consider to have met the criterion of 
paragraph (b)(4) of this section that no nitrogen stabilization claim 
has been made if:
    (i) The nitrogen stabilization claim, in whatever terms expressed, 
is made solely in compliance with a State requirement to include the 
claim in materials required to be submitted to a State legislative or 
regulatory authority, or in the labeling or other literature 
accompanying the product; and
    (ii) The State requirement to include the claim was in effect both 
before the product bearing the claim was introduced into commercial 
agronomic use, and before the effective date of this rule.
    (6) A product that meets all of the criteria of this paragraph with 
respect to one State is not thereby excluded from FIFRA regulation if 
distributed and sold in another State whose nitrogen stabilization 
statement requirement does not meet the requirements of paragraph 
(b)(5)(ii) of this section.
    (c) Human drugs. Human drugs for use in or on living man are not 
for use against ``pests'' as defined in FIFRA section 2(t). Human drugs 
are subject to regulation by the Food and Drug Administration under the 
FFDCA.
    (d) Animal drugs. Viruses, bacteria or other microorganisms on or 
in living animals are not ``pests'' under FIFRA section 2(t). A ``new 
animal drug'' as

[[Page 50714]]

defined in section 201(w) of the FFDCA, or an animal drug that FDA has 
determined is not a ``new animal drug'' is not a pesticide under FIFRA 
section 2(u). Animal drugs are subject to regulation by the Food and 
Drug Administration under the FFDCA.
    (e) Animal feeds. An animal feed containing a new animal drug is 
not a pesticide under FIFRA section 2(u). Animal feeds containg new 
animal drugs are subject to regulation by the Food and Drug 
Administration under the FFDCA.
    (f) Vitamin hormone products. A product consisting of a mixture of 
plant hormones, plant nutrients, inoculants, or soil amendments is not 
a ``plant regulator'' under FIFRA section 2(v), provided it meets the 
following criteria:
    (1) The product, in the undiluted package concentration at which it 
is distributed or sold, meets the criteria of Sec. 156.62 of this 
chapter for Toxicity Category III or IV; and
    (2) The product is not intended for use on food crop sites, and is 
labeled accordingly.

Sec. 152.8 [Amended]

    e. In Sec. 152.8, by removing paragraphs (a), (b), (c), 
introductory text, (c)(2), (c)(3), and (c)(4), and redesignating 
paragraph (c)(1) as paragraph (a) and redesignating paragraph (d) as 
paragraph (b).
    f. In Sec. 152.20, by revising paragraph (b) to read as follows:


Sec. 152.20   Exemptions for pesticides regulated by another Federal 
agency.

      *    *    *    *    *
    (b) Non-liquid chemical sterilants. A non-liquid chemical 
sterilant, except ethylene oxide, that meets the criteria of 
Sec. 152.6(a)(2) with respect to its claims and Sec. 152.6(a)(3) with 
respect to its use sites is exempted from regulation under FIFRA.

Sec. 152.25 [Amended]

    g. Section 152.25 is amended by removing paragraph (d) and 
redesignating (e) through (g) as paragraphs (d) through (f).
    h. Section 152.44 is amended by removing paragraph (b)(3), 
redesignating paragraph (b)(4) as paragraph (b)(3), and adding new 
paragraph (c) to read as follows:


Sec. 152.44   Application for amended registration.

      *    *    *    *    *
    (c) A registrant may at any time submit identical minor labeling 
amendments affecting a number of products as a single application if no 
data are required for EPA to approve the amendment (for example, a 
change in the wording of a storage statement for designated residential 
use products). A consolidated application must clearly identify the 
labeling modification(s) to be made (which must be identical for all 
products included in the application), list the registration number of 
each product for which the modification is requested, and provide 
required supporting materials (for example, labeling) for each affected 
product.
    i. By adding new subpart W to read as follows:

Subpart W--Registration of Antimicrobial Products


Sec. 152.440   General.

    (a) FIFRA section 3(h) requires EPA to establish by regulation 
procedures for the registration of certain antimicrobial pesticide 
products.
    (b) In order to register, and lawfully distribute or sell, an 
antimicrobial product, a wood preservative or an antifouling paint 
covered by FIFRA section 3(h), an applicant must comply with each of 
the following:
    (1) This subpart, which describes the requirements, procedures, 
conditions, and Agency review of applications for registration of 
antimicrobial products. This subpart W substitutes for subpart C of 
this part, which applies to all other products.
    (2) Subparts A, B, E, F, G, I, and U of this part. If any provision 
of subpart W conflicts with any provision of these subparts, subpart W 
applies instead.
    (3) Part 158 of this chapter, which describes the data requirements 
for registration of antimicrobial products, wood preservatives, and 
antifouling paints.
    (4) Part 156 of this chapter, which describes the labeling 
requirements applicable to all products. Subpart W of part 156 of this 
chapter specifies efficacy performance standards and acceptable 
labeling claims for antimicrobial products bearing public health 
claims.
    (5) Part 157 of this chapter, which establishes the criteria and 
requirements for the use of child-resistant packaging.


Sec. 152.441   Applicability.

    (a) This subpart applies to an application for registration of a 
pesticide product that is any of the following:
    (1) An antimicrobial pesticide, as defined by FIFRA section 2(mm) 
and Sec. 152.3, including a wood preservative or antifouling paint 
product that makes only claims of antimicrobial pesticidal activity. 
All sections of this subpart apply to such products.
    (2) Any product for which an antimicrobial claim is made, and which 
is used in such a manner that a new or modified clearance is required 
under FFDCA section 408 or 409. All sections of this subpart apply to 
such products, except Sec. 152.457.
    (b) This subpart does not apply to an application for registration 
of a pesticide product that is any of the following:
    (1) A wood preservative that makes any non-antimicrobial pesticidal 
claim (for example, an insecticidal or fungicidal claim), regardless of 
whether an antimicrobial claim is also made for the product.
    (2) An antifoulant product that makes any non-antimicrobial 
pesticidal claim, regardless of whether an antimicrobial claim is also 
made for the product.


Sec. 152.442   Definitions.

    Terms used in this subpart have the same definitions as in the Act 
and subpart A of this part. For the purposes of this subpart, the 
following terms are defined:
    Clearance means any of the following:
    (1) A tolerance under FFDCA section 408(b).
    (2) An exemption from the requirement of a tolerance under FFDCA 
section 408(c).
    (3) A food additive regulation under FFDCA section 409.
    (4) An approval of a medical device under FFDCA section 510(k).
    Complete application means an application for registration that 
contains all data, forms, and information required by EPA to be 
submitted with the application, and that will allow EPA to initiate 
review, notwithstanding that EPA may determine that additional 
information is required to approve the application. To be a complete 
application, each required item, and the application as a whole, must 
be determined by EPA to be complete, accurate, readable, and submitted 
in the format and number of copies required by the Agency.

[[Page 50715]]

    Major new use means a new antimicrobial use of a registered active 
ingredient, as used in FIFRA section 3(h).
    Minor amendment means an amendment to an antimicrobial registration 
that does not require the review of scientific data.
    Substantive amendment means an amendment to an antimicrobial 
registration that requires scientific review of data.


Sec. 152.443   Who may apply.

    (a) New registration. Any person may apply for new registration of 
an antimicrobial product. A person seeking a new registration for an 
antimicrobial product must submit an application for registration 
containing the information specified in Sec. 152.450. An application 
for new registration must be approved by the Agency before the product 
may lawfully be distributed or sold, except as provided by Sec. 152.30.
    (b) Amended registration. (1) Any registrant may apply for 
amendment of his/her registration to modify the composition, labeling, 
or packaging of the product. Except as provided by Sec. 152.446, a 
registrant may modify the registration only by submitting an 
application for amended registration. The applicant must submit the 
information specified in Sec. 152.450, as applicable to the change 
requested.
    (2) Except as provided by paragraph (c) of this section, the 
registrant must submit a separate application for each amendment.
    (3) If an application for amendment is required, the application 
must be approved by the Agency before the product, as modified, may 
lawfully be distributed or sold.
    (c) Consolidation of amendments. A registrant may at any time 
submit identical minor labeling amendments affecting a number of 
products as a single application if no data are required for EPA to 
approve the amendment (for example, a change in the wording of a 
storage statement for designated household products). A consolidated 
application must clearly identify the labeling modification(s) to be 
made (which must be identical for all products), list the registration 
number of each product for which the modification is requested, and 
provide required supporting materials (for example, labeling) for each 
affected product.
    (d) Alternatives to amendment. In its discretion, the Agency may:
    (1) Waive the requirement for submission of an application for 
amended registration.
    (2) Permit an applicant to modify a registration by notification or 
non-notification in accordance with Sec. 152.446.
    (e) Certification statement. In its discretion, the Agency may 
permit an applicant to certify to the Agency that the applicant has 
complied with an Agency directive or requirement with respect to any 
element of a new or amended registration. If the Agency determines that 
a requirement may be satisfied by an applicant certification, the 
Agency will provide, through a guidance document available to the 
general public, detailed instructions on a certification process. The 
guidance document will specify the content of a certification 
statement, any materials that must be submitted with the certification 
or maintained by the applicant, and the manner of submission of the 
certification.


Sec. 152.444   Alternate formulations.

    (a) A product proposed for registration must have a single, defined 
composition of active and inert ingredients, except that EPA may 
approve a basic formulation and one or more alternate formulations 
under a single registration.
    (b) An alternate formulation must meet the criteria listed in 
paragraph (b)(1) through (b)(4) of this section. The Agency may require 
the submission of data to determine whether the criteria have been met.
    (1) The alternate formulation must contain, and have the same 
certified limits for, each active ingredient in the basic formulation.
    (2) If the alternate formulation contains an inert ingredient or 
impurity of toxicological significance, the formulation must have the 
same upper certified limit for that substance as the basic formulation.
    (3) The label text of the alternate formulation product must be 
identical to that of the basic formulation.
    (4) The analytical methods required under Sec. 158.180 of this 
chapter must be suitable for use on both the basic formulation and the 
alternate formulation.
    (c) Notwithstanding the criteria in this section, the Agency may 
determine that an alternate formulation must be separately registered. 
If EPA makes this determination, the Agency will notify the applicant 
of its determination and its reasons. Thereafter the application for an 
alternate formulation will be treated as an application for new 
registration.


Sec. 152.445   Types of antimicrobial applications.

    The following types of applications are identified solely for 
purposes of this subpart, in order to establish review periods. 
Identification of application types in this section does not modify 
similar terms used elsewhere in EPA regulations. Application categories 
generally differ based upon factors related to the active ingredient 
status, the product formulation type, the uses proposed, and whether 
data are required with the application. An application may fall into 
only one category, as determined by EPA.
    (a) Application for registration of a food or feed use. (1) Any 
application for registration that proposes a use that would require the 
establishment of a new or modified clearance under the FFDCA. Under the 
FFDCA, a clearance must be granted, either by EPA or by FDA, for uses 
that might result, directly or indirectly, in residues in raw or 
processed food or animal feed.
    (2) The review periods in Sec. 152.457 do not apply to applications 
covered by paragraph (a)(1) of this section. Such applications require 
significantly more data, require a longer review time, and are subject 
to formal approval by regulation under the FFDCA.
    (b) Application for new registration--(1) New active ingredient. An 
application for registration of a new product containing any active 
ingredient that is not contained in a currently registered product.
    (2) Substantially similar product. An application for new 
registration of a product that meets all of the criteria in this 
paragraph.
    (i) Formulation. The product formulation contains the same active 
ingredients and is substantially similar in composition to a cited 
currently registered product.
    (ii) Uses. The proposed uses are substantially similar to the uses 
on the label of the cited product. The proposed product may bear fewer 
uses than the cited product, but may not bear expanded uses or 
different uses or claims.
    (iii) Method of data support. The application relies solely upon 
data from a substantially similar registration for support (with the 
exception of certain product chemistry data, which must be submitted 
for all new products) and does not require the submission of efficacy 
data.
    (3) Identical product. An application for registration of a product 
that meets both of the criteria in this paragraph.
    (i) Formulation. The formulation (including inert ingredients) is 
identical in composition to a cited currently registered formulation. 
Typically such a product either is a currently registered formulation 
that is being repackaged as a new product without separate

[[Page 50716]]

production, or is a formulation of identical composition to another 
product that is being separately produced according to specifications 
provided by the registrant of the cited product.
    (ii) Uses and claims. The proposed uses are identical to those on 
the cited product, with no deviation in use sites or directions for 
use. A product may have fewer uses than on the cited product, but not 
different or expanded uses or claims.
    (4) New product with major new use. An application for new 
registration that also proposes a ``major new use,'' as described in 
paragraph (c)(1) of this section. Any application for a new 
registration that proposes only an additional or different use that is 
not a major new use will be considered to be a new registration 
described in paragraph (b)(5) of this section.
    (5) Other new product. Any application for new registration that 
does not meet the criteria of paragraph (b)(1) through (b)(4) of this 
section. These products usually require the submission of data. 
Examples of what would be included in this category are applications 
for registration of a product of any of the types listed below.
    (i) The product is a formulation of different active ingredients 
than is contained in any currently registered product.
    (ii) The product contains the same active ingredients, but is in a 
different physical form (liquid, powder) than any other registered 
product containing the same active ingredients, or is not substantially 
similar in composition to a cited currently registered product.
    (iii) The product has any unregistered source of any active 
ingredient, regardless of the fact that the active ingredient is 
currently registered in another product. Use of an unregistered source 
of active ingredient requires review of supporting data for the 
unregistered ingredient.
    (iv) The product has an additional use that is not currently 
registered for any substantially similar product.
    (v) The product requires the submission of efficacy data because 
the formulation is not identical to another product.
    (c) Amendments to registration--(1) Major new use. An application 
for amended registration to add a major new use that is not currently 
registered for one or more of the active ingredients in the product. 
The major new use would generally be significantly different in the 
manner of use and exposure to humans or the environment from other 
registered use patterns for the active ingredient.
    (2) Substantive amendment. An amendment that is not a major new 
use, and that requires scientific review of data. These include, but 
are not limited to, the following types of amendments:
    (i) Any amendment that contains a data submission.
    (ii) The addition of a use that has been approved for another 
registered product containing the same active ingredients, but which is 
not a substantially similar product as the registration for which the 
amendment is sought.
    (iii) Except as permitted by Sec. 152.446, Notifications and non-
notifications, a change in precautionary or other hazard statements, 
use instructions, minor changes in ingredients that do not modify label 
statements, change in use concentrations, method of application, or 
pests.
    (3) Minor amendment. An amendment to an existing registration which 
does not require scientific review of any type. In no case does an 
application for a minor amendment contain data for review. A minor 
amendment might include, but is not limited to, changes for which EPA 
must:
    (i) Examine briefly or determine the applicability of previously 
submitted data (without scientific evaluation of such data).
    (ii) Compare composition, characteristics or labeling with other 
products.
    (iii) Evaluate the adequacy of the applicant's data citations or 
method of support.
    (iv) Determine whether an adequate basis exists for a proposed 
label statement.
    (v) Determine whether a proposed use is substantially similar to an 
approved use for a cited substantially similar product.


Sec. 152.446   Notifications and non-notifications.

    (a) Changes permitted by notification--(1) Notifications permitted 
by statute. A registrant of an antimicrobial product may add relevant 
information on product efficacy, product composition, container 
composition or design, or other characteristics that do not relate to 
pesticidal claims or activity. An example of a product efficacy claim 
that does not relate to pesticidal claims or activity would be a 
cleaning, deodorizing, or polishing claim.
    (2) Notifications permitted by EPA. In addition, EPA may determine 
that certain minor modifications to registration having no potential to 
cause unreasonable adverse effects to the environment may be 
accomplished by notification to the Agency, without requiring the 
registrant to obtain Agency approval. If EPA so determines, it will 
issue a notice to registrants describing the types of modifications 
permitted by notification.
    (b) Procedure for notification. All notifications must be submitted 
in accordance with the procedures of this paragraph and any 
supplemental notice to registrants.
    (1) Submission. A registrant must submit the notification to the 
Agency at least 60 days before distribution or sale of a product as 
modified.
    (2) Substantiation. The registrant must retain, and submit to the 
Agency upon request, substantiating information or data supporting the 
proposed modification. These data need not be submitted with the 
notification unless specified in a notice issued in accordance with 
paragraph (a)(2) of this section. The substantiating information may be 
required, however, in accordance with paragraph (b)(4) of this section 
if the notification is disapproved.
    (3) Agency decision. Within 30 days after receipt, the Agency will 
notify the registrant in writing if the notification is disapproved and 
state the reasons why it is unacceptable.
    (4) Objection. A registrant may file an objection to a disapproval 
in writing not later than 30 days after receipt of the Agency's 
disapproval. If the basis for the disapproval is that substantiating 
information is needed, the registrant must submit such information as 
part of the objection. A decision by EPA after receipt and 
consideration of an objection is a final agency action.
    (5) Distribution or sale. A registrant may not distribute or sell a 
product for which a modification by notification is proposed until the 
registrant receives EPA notice of approval, or until 60 days after 
submission of the notification, whichever comes first. A registrant may 
not sell or distribute a product bearing a disapproved modification.
    (c) Changes permitted without notification. EPA may determine that 
certain minor changes to registration having no potential to cause 
unreasonable adverse effects to the environment may be accomplished 
without notification to or approval by the Agency. If EPA so 
determines, it will issue a notice to registrants describing the types 
of changes permitted without notification (known as non-notifications). 
A registrant may distribute or sell a product changed as permitted by 
such notice without notification to or approval by the Agency.
    (d) Effect of non-compliance. Notwithstanding any other provision 
of

[[Page 50717]]

this section, if the Agency determines that a product has been modified 
through notification or without notification in a manner inconsistent 
with paragraphs (a) through (c) of this section or any notice issued 
thereunder, EPA may initiate regulatory or enforcement action, or both, 
without first providing the registrant with an opportunity to submit an 
application for amended registration.


Sec. 152.447   Consultation with EPA.

    (a) Optional consultation. An applicant may consult the Agency at 
any time prior to submitting an application. Consultations should be by 
the most efficient and least time-consuming method available that 
satisfies the applicant's need. For minor questions or guidance, fax 
and e-mail are preferred, so that the Agency may respond both rapidly 
and in writing.
    (b) Meetings. If a meeting is desired, applicants should contact 
the appropriate team leader or Branch Chief and provide a proposed 
agenda, list of likely attendees, and requested date(s). If EPA agrees 
that a meeting would be productive, EPA will schedule the meeting, 
honoring the applicant's requested times insofar as practicable, and 
will invite needed Agency personnel. EPA may choose not to meet with 
applicants if matters can be resolved by other means.
    (c) Required consultation. An applicant must consult the Agency 
before submitting an application for registration if:
    (1) The application is for a new chemical or major new use. It is 
strongly recommended that this consultation be a meeting or conference 
call with written confirmation of any agreements.
    (2) The applicant wishes to develop data using different or 
modified protocols for required efficacy studies, or if no test method 
is specified. In some cases, EPA approval of alternate protocols and 
test standards is required. Consultation would typically consist of a 
written explanation of the modifications proposed or the proposed 
protocol, which EPA would approve in writing.
    (d) Written determinations. An applicant may rely upon regulatory 
determinations only if in writing from EPA.
    (e) Reliance on EPA determinations. EPA will not change the 
regulatory decisions contained in a written determination issued under 
paragraph (d) of this section unless:
    (1) EPA concludes that its determination was in error.
    (2) The applicant modifies the circumstances upon which the 
determination was based or EPA determines that the circumstances are 
other than described by the applicant.
    (3) The applicant fails to submit the application in a timely 
manner, such that EPA's determination no longer comports with Agency 
regulations or policy; or
    (4) EPA has information that raises concerns that an unreasonable 
adverse effect on the environment may result unless it changes its 
determination.


Sec. 152.450   Contents of application.

    Each application for registration must include the data, 
information, and forms listed in this section.
    (a) Application for registration. The applicant must submit an 
application form provided by the Agency. The application form is 
required for all applications, both new and amended, as well as for 
notifications under Sec. 152.446. To be complete:
    (1) The applicable parts of the form must be properly and 
accurately filled in, according to the instructions provided with the 
form.
    (2) The applicant must identify on the form which type of 
application the applicant believes is being submitted for purposes of 
review time computation. Types of applications are listed in 
Sec. 152.445.
    (3) If the application relies on an ``identical'' or 
``substantially similar'' product, the applicant must provide the EPA 
Registration Number of the product claimed as identical or 
substantially similar.
    (4) The form must be signed by an authorized representative of the 
applicant and must be dated.
    (b) Authorization for agent. The applicant must submit a letter of 
authorization designating an agent residing in the United States if the 
applicant is located outside of the United States or if the applicant 
wishes to use an agent. To be complete, the authorization must:
    (1) Be on the applicant's company letterhead.
    (2) Provide identifying information for the agent, including name, 
address, and telephone numbers (fax and e-mail are requested if 
available).
    (3) Affirm that the person designated is authorized to serve as 
agent with respect to specified applications or registrations and 
provide a clear description of the products or applications covered and 
any limitations on the authorization.
    (4) Be signed (with name and title) by an authorized representative 
of the applicant and be dated.
    (c) Summary of application. An application for registration must 
contain a publicly releasable summary of the application, including a 
list of the data submitted or cited in support of the application, 
together with a brief summary of the results of any studies submitted. 
This summary may be combined with that required for any other purpose.
    (d) Statement of Formula. (1) The applicant must submit a Statement 
of Formula that identifies the composition of the product proposed for 
registration. A Statement of Formula is required for:
    (i) Each application for new registration.
    (ii) Each application for amended registration that proposes any 
change in the product composition or a change in other information on 
the previous Statement of Formula.
    (iii) Each notification under Sec. 152.446 which affects the 
composition of the product.
    (2) To be complete, the Statement of Formula must be accurately 
filled out with all required information, and must be signed by an 
authorized representative of the applicant.
    (e) Labeling. (1) The applicant must submit the number of copies of 
draft labeling specified by the Agency. Generally four copies of draft 
labeling must be submitted. Draft labeling is required for:
    (i) Each application for new registration.
    (ii) Each application for amended registration, if the amendment 
proposes a label change or a labeling change is otherwise necessitated 
by the amendment (e.g., a change in composition affecting the 
labeling).
    (iii) Each notification under Sec. 152.446 that modifies any 
portion of the labeling.
    (2) To be complete, the labeling submission must:
    (i) Include both the product label and any supplemental labeling, 
brochures, or other printed material that is intended to accompany the 
product in distribution or sale.
    (ii) In the case of an amendment to existing labeling, be identical 
in wording to the last approved labeling, except for proposed changes 
(and any previously accepted notification), which must be marked.
    (iii) Be suitable for photocopying. In general, highlighting does 
not photocopy; changes need to be marked or circled in black ink. 
Product packaging bearing the labeling is not acceptable for this 
purpose.
    (f) Method of support documentation. The applicant must submit 
documentation of the method of support that will be used to satisfy 
each data requirement that applies to the

[[Page 50718]]

application. Various forms provided by the Agency must be submitted to 
document the applicant's choices. This paragraph summarizes data 
support requirements. The applicant must comply with subpart E of this 
part, which contains detailed requirements and exceptions to the data 
support process.
    (1) In general, the following choices for each data requirement are 
available:
    (i) The applicant may submit the data. In all cases, an applicant 
may submit a study that satisfies a data requirement. Typically certain 
data must be submitted (product chemistry) and may not be cited. Refer 
to paragraph (g) of this section for information on data submission.
    (ii) The applicant may cite the data with permission or offer to 
pay. If the data are exclusive use data, the applicant must have 
written permission from the data submitter. If the data are subject to 
compensation provisions, the applicant must have made appropriate 
offers to pay to each data submitter(s). Refer to paragraph (f)(2) of 
this section for the forms used to properly document citation of data.
    (iii) The applicant may request in writing a waiver of the data 
requirement, together with a rationale for each waiver requested. A 
waiver request without a rationale is not complete.
    (2) To be complete, the applicant who submits or cites data to 
satisfy any data requirement must submit, as applicable, one or more of 
the following:
    (i) A data reference sheet (data matrix). This is a listing of all 
data requirements applicable to the product, identifying the means of 
satisfying each requirement, and must be submitted whenever an 
applicant submits his/her own data or uses the selective method of data 
support (see Sec. 152.90). To be complete, each citation of data must 
include the Master Record Identification number, if known, or contain 
sufficient detail (title, date of submission, name and EPA identifying 
number of product) that EPA may clearly identify the item of data in 
its files.
    (ii) A formulator's exemption form. This form is used when the 
applicant claims an exemption from certain data requirements because 
the applicant produces his/her product using a purchased registered 
source product. A single formulator's exemption form may be used for 
all data requirements to which the exemption applies. The form must 
identify the registration number of each source product.
    (iii) Certification with respect to citation of data. This form is 
used to certify that the applicant has complied with all requirements 
pertaining to data submission and citation. The form must be submitted 
with each application for registration.
    (g) Data and information. (1) The applicant must satisfy data 
requirements by submitting or properly citing data and information in 
support of the application, unless the applicant obtains a waiver of 
the data requirement, or unless EPA permits an alternate method of 
satisfying data requirements (such as certification). Data requirements 
are found in part 158 of this chapter.
    (2) To be complete, the data submission must meet the following 
criteria:
    (i) Final report of study. The submission must contain a final 
report of each study, including all information specified in Agency 
guidance (e.g., identity of substance tested).
    (ii) Summary of results of data. The application must include a 
publicly releasable summary of the results of each study submitted. The 
results of all studies may be consolidated into a single summary.
    (iii) Format. Each study individually, and the data submission as a 
whole, must conform to Agency requirements for formatting and 
presentation, as specified in Sec. 158.32 of this chapter and Agency 
guidance.
    (iv) Confidential business information (CBI). Each study must 
conform to Agency requirements in Sec. 158.33 of this chapter with 
respect to identification, marking, and presentation of CBI.
    (v) Certification of Good Laboratory Practice (GLP) compliance. 
Each study must include a certification in accordance with Sec. 160.12 
of this chapter.
    (vi) Identification of studies demonstrating potential adverse 
effects. Each study that meets the criteria of Sec. 158.34 of this 
chapter for potential adverse effects must be identified and the 
certification statement required by that section must be included. The 
studies to which this requirement applies are subchronic and chronic 
toxicity studies.
    (h) Data or information pertaining to adverse effects. An applicant 
must submit any factual information regarding unreasonable adverse 
effects of this pesticide on man or the environment. The information 
that must be submitted is that which would be required to be reported 
under FIFRA section 6(a)(2) if the product were registered (see part 
159 of this chapter). This requirement applies to each application for 
new registration. The requirement does not apply to an application for 
amended registration. To be complete, submission of adverse effects 
information must be in accordance with part 159 of this chapter.
    (i) Food use clearance. If the application proposes a use of the 
pesticide on food or feed crops, or if the intended use of the 
pesticide results or may be expected to result, directly or indirectly, 
in pesticide chemical residues in or on food or feed, the applicant 
must submit one of the following:
    (1) A citation to each clearance that covers the proposed food or 
feed use(s).
    (2) A petition under FFDCA section 408 requesting the establishment 
of a food clearance for each ingredient for which there is no current 
clearance. Requirements for pesticide petitions are contained in 40 CFR 
part 180. If a petition is required, an application for registration is 
not complete unless all requirements for the petition are satisfied.
    (3) Evidence of acceptance of a petition for a food additive 
regulation by the FDA, if a food additive regulation is required. A 
copy of the notice of filing of the petition in the Federal Register is 
acceptable for this purpose.
    (j) Documentation of pre-submission consultation. If a pre-
submission consultation is required by Sec. 152.447, the applicant must 
submit written documentation that the consultation took place, and a 
copy of any resulting regulatory decisions regarding the application or 
its review (for example, agreement as to the type of application being 
submitted, or specific data requirements imposed or waived).
    (k) Data reviews conducted by other regulatory authorities. The 
applicant must state whether the data supporting the application have 
been, or are being, reviewed by State, Federal, or other national 
regulatory authorities. If so, the applicant must identify the 
reviewing authority and purpose of the review and must submit any 
available data reviews conducted by such regulatory authorities that 
are in the applicant's possession. The applicant is not required to 
obtain regulatory reviews for this purpose.
    (l) Other clearances. If the applicant is required to obtain 
clearances or approvals from other Federal (not State) agencies before 
a product may be distributed and sold, or used as proposed on the 
label, the applicant must submit either:
    (1) A copy of each such clearance or approval if already obtained; 
or
    (2) A copy of a request to the appropriate agency for each such 
clearance or approval.
    (m) Packaging--(1) Child-resistant packaging (CRP). If the product 
is

[[Page 50719]]

required by part 157 of this chapter to be distributed and sold only in 
CRP, or if the product will be sold in CRP, the applicant must submit a 
certification statement that the product meets the criteria for CRP in 
Sec. 157.32 of this chapter.
    (2) In no case is actual product packaging to be submitted with an 
application for registration. If EPA needs to evaluate the actual 
product packaging, it will request submission.
    (n) Product samples. In no case is a sample of the product to be 
submitted with an application. Product or ingredient samples may be 
required by the Agency for various purposes, but will be requested 
separately and must be submitted to the address in the request.
    (o) Self-addressed notice for completeness determination. (1) An 
applicant may (but is not required to) provide a postcard (preferred) 
or form letter that EPA may use for notification of receipt of an 
application that EPA has preliminarily determined is complete.
    (2) A postcard or form letter for this purpose must be addressed to 
the applicant at his/her address of record, stamped with sufficient 
U.S. postage, and provide a means (checkoff, space, box) for EPA to 
record the registration number or file symbol of the application, the 
fact that the application is complete, the date of EPA receipt, and the 
expected date for decision based upon the type of application.
    (3) If a means of notifying the applicant is not provided, EPA will 
not otherwise notify an applicant in writing that the application is 
complete. EPA may, but is not required to, telephone or e-mail an 
applicant who does not provide written means of notification.
    (p) Fees. If fees are required to be submitted for any application, 
or in conjunction with a petition for a clearance associated with an 
application, such fees must be submitted in accordance with Agency 
guidance. An application is not complete unless required fees have been 
submitted.
    (q) Authorizations. (1) The applicant is requested, but not 
required, to provide authorization for EPA to share studies submitted 
by the applicant, or EPA's reviews of such studies, with other 
regulatory authorities, including Federal, State, or national bodies 
that may regulate pesticides. Such authorization would apply only to 
the exchange of data or EPA reviews of data that might contain 
Confidential Business Information (CBI) or information protected under 
FIFRA section 10(g), unless the applicant provided a broader disclosure 
authorization.
    (2) If the applicant chooses to authorize any degree of data/review 
sharing, the applicant should include with his/her application, on 
company letterhead and signed by an authorized representative of the 
applicant, one of the following:
    (i) A blanket authorization for EPA to exchange data or EPA data 
reviews pertaining to all of the applicant's products.
    (ii) A specific authorization for EPA to exchange data or EPA data 
reviews pertaining to an ingredient(s) or product(s) designated in the 
authorization.
    (iii) A specific authorization for EPA to exchange data or EPA data 
reviews pertaining to data submitted with the application.
    (iv) Any other form of authorization, identifying the ingredients, 
products or data to which the authorization pertains and limitations 
upon the authorization.
    (3) If an applicant chooses not to authorize EPA data/review 
sharing at the time of application, EPA may, in its discretion, 
disclose data or reviews in those circumstances where no authorization 
is needed, and seek consent for disclosure where needed on a case-by-
case basis.


Sec. 152.451   How to submit applications.

    (a) Applications must be submitted to the Agency by U.S. mail, 
courier service, or in person. EPA provides in guidance documents or 
upon request the appropriate address for each type of delivery. 
Applications may not be submitted electronically or by fax.
    (b) EPA will not automatically provide evidence of receipt of an 
application. An applicant who wishes confirmation of delivery to EPA 
should use certified mail or courier services that provide 
confirmation.


Sec. 152.455   Action on applications.

    (a) Incomplete application. EPA will screen each application for 
completeness, as specified in Sec. 152.450. If EPA determines that the 
application is not complete, EPA will notify the applicant in writing 
of the deficiency(ies) in the application. EPA will not place into 
review, or compute review periods, for any application it finds 
incomplete.
    (b) Preliminary determination of complete application. If EPA makes 
a preliminary determination that the application is complete, it will 
place the application into review. The appropriate review period in 
Sec. 152.457 will be computed from the date of receipt by EPA of the 
last item that completes the application.
    (c) EPA review of application. EPA will review each application for 
which a preliminary determination of completeness has been made. EPA 
will notify the applicant in writing of its decision on the application 
upon completion of all required reviews. EPA may, in its discretion, 
communicate with the applicant informally on the progress and interim 
results of the review. Such informal communications do not constitute a 
decision on the application, and do not affect the review period.
    (d) Decision on application. When all reviews are completed, EPA 
will take one of the following actions on the application:
    (1) Approve the application. (i) EPA will approve an application 
for registration if it meets the criteria of Sec. 152.112, 
Sec. 152.113, or Sec. 152.114, as applicable.
    (ii) If EPA approves the application, EPA will issue a Notice of 
Registration and provide the applicant a copy of the stamped approved 
labeling, together with any labeling modifications that must be made. 
Before distributing or selling the pesticide product, the applicant 
must submit final printed labeling to the Agency, modified as specified 
by EPA in approving the registration and in the number of copies 
required by EPA. Thereafter, the registrant may distribute and sell the 
product under the terms approved by EPA.
    (iii) If EPA approves the application for a product on terms that 
differ from those requested by the applicant, the applicant may file a 
written objection and request that EPA reconsider the terms that are 
objectionable. An objection must be filed within 30 days of the date on 
which EPA approved the application, and must set out in detail the 
basis of the objection and the alternative terms of registration 
requested. The applicant may not distribute or sell the product until 
the objection is resolved. EPA will use its best efforts to respond 
within 45 days of receipt of a timely, written objection.
    (2) Determine that the application remains incomplete. EPA may 
determine that, notwithstanding its preliminary determination of 
completeness, the application remains incomplete. If EPA so determines, 
it will notify the applicant of the deficiencies in the application. 
The applicant's resubmission will be treated in accordance with either 
paragraph (d)(2)(i) or (d)(2)(ii) of this section.
    (i) Qualifying resubmission. EPA will treat a complete and timely 
response

[[Page 50720]]

from the applicant as a ``qualifying resubmission'' subject to the 
review period in Sec. 152.457(e), and will make a final decision on the 
application without recomputing a full second review period provided by 
Sec. 152.457(c) or (d), if:
    (A) The original application has a review period of 120 
days;
    (B) EPA determines, in its sole discretion, that the deficiency is 
less serious; and
    (C) The deficiency is corrected within 30 days of receipt of EPA's 
notice to the applicant.
    (ii) Non-qualifying resubmission. EPA will recompute a second full 
review period beginning on the date of receipt of the last item 
completing the application, and will make a final decision on the 
application within the review periods in Sec. 152.457(c) or (d), as 
applicable, if:
    (A) The original application has a review period of >120 days;
    (B) EPA determines, in its sole discretion, that the deficiency is 
serious; or
    (C) The applicant does not respond within 30 days.
    (3) Determine that the applicant has not supplied all data or 
information required to determine the acceptability of the 
registration. EPA may determine that, despite its preliminary 
determination of completeness, the applicant has not supplied 
sufficient information to issue a registration decision. If EPA so 
determines, it will notify the applicant, identify the additional 
information or data needed, and require that the applicant submit, by a 
specified date, the information or data needed. As of the date of EPA's 
notification to the applicant, the review period will stop. The elapsed 
time between date of notification and receipt of response will not be 
counted in computing the date for a decision under Sec. 152.457. Based 
upon the nature of the deficiencies, the time anticipated for the 
applicant to correct the deficiencies, and the additional time needed 
by EPA to review the material submitted in response to the notice of 
deficiency, EPA will specify in its notification one of two review 
period decisions:
    (i) EPA may specify that the review period will resume as of the 
date of receipt of the applicant's complete and timely response; or
    (ii) EPA may specify that the review period will resume after a 
specified period following receipt of the applicant's complete and 
timely response.
    (4) Deny the application for failure to submit required 
information. If, after notification in accordance with paragraph (d)(3) 
of this section, the applicant does not respond, or does not provide 
all required data or information within the specified time, EPA may 
deny the application in accordance with the procedures of Sec. 152.118. 
These procedures provide that EPA will issue a Notice of Intent to Deny 
(NOID) the application, stating the reasons and factual basis for 
denial, and permit the applicant 30 days to take corrective action. The 
Agency's issuance of a NOID would constitute the action required by 
FIFRA section 3(h) to notify an applicant of the Agency's decision, and 
the 30 days allowed for correction or other action would not be counted 
in the computation of the review period. Alternatively, EPA may 
determine that the application remains incomplete, in accordance with 
paragraph (d)(2) of this section. In either case, any subsequent 
submission will be treated as if it were an original application, and 
the review period will start over upon receipt of a complete 
application.
    (5) Deny the application for failure to meet the registration 
standard. EPA may deny an application for registration if the Agency 
determines that, based upon review of a complete application and all 
data required by the Act, this part and part 158 of this chapter, the 
product does not meet the criteria of FIFRA section 3(c)(5) or (7), as 
specified in Sec. 152.112, Sec. 152.113, or Sec. 152.114. If EPA 
proposes to deny an application on this basis, the Agency will follow 
the procedures of Sec. 152.118. The Agency's issuance of a NOID would 
constitute the action required by FIFRA section 3(h) to notify an 
applicant of the Agency's decision, and the 30 days allowed for 
correction or other action would not be counted in the computation of 
the review period.


Sec. 152.457   Review periods for applications.

    EPA will complete review of, and make a decision on whether to 
approve, each application type listed in Sec. 152.445 within the review 
periods given in this section. The statutory timeframes are based upon 
submission of a complete application. The process of submission is not 
complete until EPA has received the application. Accordingly, review 
periods are computed from the date that EPA receives the last item of 
an application that it determines thereafter is a complete application.
    (a) Applications involving food/feed uses. The time frames in this 
section do not apply to applications involving food or feed uses that 
may require a clearance under the FFDCA. EPA will attempt to review 
such applications in a time commensurate with similar non-food actions, 
but because these applications may require significantly more data and 
more formal procedures for approval, EPA has not established any review 
periods for such applications.
    (b) Fast-track applications. An application that qualifies as a 
fast-track application under FIFRA section 3(c)(3)(B)(i) will be 
reviewed within 90 days after receipt of a complete application.
    (c) Application for new registration. Except as provided in 
paragraph (e) of this section, EPA will issue a decision on a complete 
application for new registration within the review period listed in the 
table to this paragraph.

    (f) Applicant recourse for failure to issue decision within review 
period. If EPA has not notified the applicant that the application is 
approved or denied within the review period set out in this section, or 
within an alternative review period agreed to by EPA and the applicant, 
the applicant may seek judicial review under 5 U.S.C. 7.


Sec. 152.458   Duration of registration.

    (a) Products not bearing public health claims. The registration of 
a product that bears no public health claim, as defined in Sec. 156.443 
of this chapter, will be effective until EPA takes action to suspend or 
cancel the registration.
    (b) Products bearing public health claims. The registration of a 
product bearing a public health claim, as defined in Sec. 156.443 of 
this chapter, will expire 5 years after the date specified in paragraph 
(b)(1) or (b)(2) of this section, as applicable, unless the 
requirements of paragraph (b)(3) of this section have been met. At the 
end of each 5-year period thereafter, the registration will expire 
unless the requirements of paragraph (b)(3) of this section have been 
met with respect to the most recent 5-year period.
    (1) New products. The 5-year period for products first registered 
after the effective date of this rule begins on the date of 
registration. EPA will incorporate the 5-year term of registration in 
the notice of registration.
    (2) Existing products. The 5-year period for products already 
registered as of the effective date of this rule begins on the earliest 
of the following dates:
    (i) The date of EPA approval of the first amendment after the 
effective date of this rule. EPA will incorporate the 5-year term of 
registration into the letter of approval.
    (ii) The date of EPA approval of reregistration of the product 
under FIFRA section 4. EPA will incorporate the 5-year term of 
registration into the letter of reregistration.
    (iii) A date certain approximately 1 year after the effective date 
of this rule.
    (3) The registration will not expire if:
    (i) Within 1 year before each expiration date of the registration, 
the registrant completes one or more chemical analyses of the product 
according to the analytical method submitted under Sec. 158.180 of this 
chapter.
    (ii) Within 1 year before each expiration date of the registration, 
the registrant completes efficacy testing for each public health claim 
on the label in accordance with the most current Agency guidelines.
    (iii) No later than 90 days before each expiration of the 
registration, the registrant submits to the Office of Pesticide 
Programs at EPA a written certification, signed by an authorized 
representative of the registrant. The registrant must certify to each 
of the following:
    (A) The registrant has conducted the required tests, identifying 
the tests that were conducted.
    (B) Each test was conducted in accordance with the most current EPA 
guidelines for product composition testing and efficacy testing, and 
with applicable Good Laboratory Practice standards of part 160 of this 
chapter.
    (C) Based upon the product composition tests, the product 
composition continues to conform to the most recent Statement of 
Formula approved by EPA.
    (D) Based upon the efficacy testing, the product meets applicable 
performance standards of part 156, subpart W, for each public health 
claim made.
    (E) The test results are maintained with the registrant and will be 
submitted to EPA upon request.
    (4) If the registration expires, the product will be deemed to be 
an unregistered product. EPA will permit the continued distribution and 
sale of existing stocks of the product by the registrant for 90 days 
after the expiration date, and by others for 1 year after the 
expiration date, unless the Administrator determines that a different 
time period is needed.


Sec. 152.459   Terms and conditions of registration.

    (a) General conditions. A registration shall be subject to such 
terms and conditions as EPA may establish at the time of issuance, 
including, but not limited to, the terms and conditions in 
Sec. 152.115. Such terms and conditions will be specified in the notice 
of registration or letter approving an amendment of registration.
    (b) Submission of efficacy data for non-public health products. 
Efficacy data for non-public health products are not generally required 
to be submitted with an application for registration, but are required 
to be maintained by the registrant. Upon request by EPA, the registrant 
must submit the efficacy data required by part 158 for a non-public 
health product. EPA will notify the registrant and allow 30 days from 
date of receipt for submission of the data.

Subpart D--Human Hazard and Precautionary Statements


Sec. 156.60   General.

    Each product is required to bear hazard and precautionary 
statements for humans and for domestic animals (if applicable) as 
prescribed in this subpart. Hazard statements describe the type of 
hazard that may occur, while precautionary statements will either 
direct or inform the user of actions to take to avoid the hazard or 
mitigate its effects.
    (a) Location of statements--(1) Front panel statements. The signal 
word, child hazard warning, and, in certain cases, the first aid are 
required to appear on the front panel of the label, and also in any 
supplemental labeling intended to accompany the product in distribution 
or sale.
    (2) Statements elsewhere on label. Hazard and precautionary 
statements

[[Page 50722]]

not required on the front panel may appear on other panels of the 
label, and may be required also in supplemental labeling. These 
include, but are not limited to, the human hazard and precautionary 
statements, domestic animal statements if applicable, Notes to 
Physician, and physical or chemical hazard statements.
    (b) Placement and prominence--(1) Front panel statements. All 
required front panel warning statements shall be grouped together on 
the label, and shall appear with sufficient prominence relative to 
other front panel text and graphic material to make them unlikely to be 
overlooked under customary conditions of purchase and use. The table to 
this paragraph shows the minimum type size requirements for the front 
panel warning statements for various front panel sizes:

    (2) Other required statements. All other hazard and precautionary 
statements must be at least 6 point type.


Sec. 156.62   Toxicity category.

    This section establishes four Toxicity Categories for acute hazards 
of pesticide products, Category I being the highest toxicity category. 
Most human hazard, precautionary statements, and human personal 
protective equipment statements are based upon the Toxicity Category of 
the pesticide product as sold or distributed. In certain cases, 
statements based upon the Toxicity Category of the product as diluted 
for use are also permitted. A Toxicity Category is assigned for each of 
five types of acute exposure, as specified in the table to this 
paragraph.

Sec. 156.64   Signal word.

    (a) Requirement. Except as provided in paragraph (a)(4) of this 
section, each pesticide product must bear on the front panel a signal 
word, reflecting the highest Toxicity Category (Category I is the 
highest toxicity category) to which the product is assigned by any of 
the five routes of exposure in Sec. 156.62. The signal word must also 
appear together with the heading for the human precautionary statement 
section of the labeling (see Sec. 156.70).
    (1) Toxicity Category I. Any pesticide product meeting the criteria 
of Toxicity Category I for any route of exposure must bear on the front 
panel the signal word ``DANGER.'' In addition, if the product is 
assigned to Toxicity Category I on the basis of its oral, inhalation or 
dermal toxicity (as distinct from skin and eye irritation), the word 
``Poison'' must appear in red on a background of distinctly contrasting 
color, and the skull and crossbones symbol must appear in immediate 
proximity to the word ``Poison.''
    (2) Toxicity Category II. Any pesticide product meeting the 
criteria of Toxicity Category II as the highest category by any route 
of exposure must bear on the front panel the signal word ``WARNING.''
    (3) Toxicity Category III. Any pesticide product meeting the 
criteria of Toxicity Category III as the highest category by any route 
of exposure must bear on the front panel the signal word ``CAUTION.''
    (4) Toxicity Category IV. A pesticide product meeting the criteria 
of Toxicity Category IV by all routes of exposure is not required to 
bear a signal word. If a signal word is used, it must be ``CAUTION.''
    (b) Use of signal words. In no case may a product:

[[Page 50723]]

    (1) Bear a signal word reflecting a higher Toxicity Category than 
indicated by the route of exposure of highest toxicity, unless the 
Agency determines that such labeling is necessary to prevent 
unreasonable adverse effects on man or the environment;
    (2) Bear a signal word reflecting a lesser Toxicity Category 
associated with a diluted product. Although precautionary statements 
for use dilutions may be included on label, the signal word must 
reflect the toxicity of the product as distributed or sold; or
    (3) Bear different signal words on different parts of the label.


Sec. 156.66   Child hazard warning.

    (a) Each pesticide product must bear on the front panel of the 
label the statement ``Keep Out of Reach of Children.'' The statement 
must appear on a separate line in close proximity to the signal word. 
The statement is required on Toxicity Category IV products that do not 
otherwise require a signal word.
    (b) EPA may waive the requirement, or require an alternative child 
hazard warning, if:
    (1) The applicant can demonstrate that the likelihood of exposure 
of children to the pesticide during distribution, marketing, storage or 
use is remote (for example, an industrial use product); or
    (2) The pesticide is approved for use on children (for example, an 
insect repellent).
    (c) EPA may approve an alternative child hazard warning that more 
appropriately reflects the nature of the pesticide product to which 
children may be exposed (for example, an impregnated pet collar). In 
this case, EPA may also approve placement on other than the front 
panel.


Sec. 156.68   First aid statement.

    (a) Product as sold and distributed. Each product must bear a first 
aid statement if the product has systemic effects in Category I, II, or 
III, or skin or eye irritation effects in Category I or II. First aid 
statements are based upon the Toxicity Category by each route of 
exposure for the product.
    (b) Product as diluted for use. If the product labeling bears 
directions for dilution with water prior to use, the label may also 
include a statement describing how the first aid measures may be 
modified for the diluted product. Such a statement must reflect the 
Toxicity Category(ies) of the diluted product, based upon data for the 
route of exposure (or calculations if appropriate). If the labeling 
provides for a range of use dilutions, only that use dilution 
representing the highest concentration allowed by labeling may be used 
as the basis for a statement pertaining to the diluted product. The 
statement for a diluted product may not substitute for the statement 
for the concentrate, but augments the information provided for the 
concentrate.
    (c) Heading. The heading of the statement must be ``First Aid.''
    (d) Location of first aid statement. The first aid statement must 
appear on the front panel of the label of all products assigned to 
Toxicity Category I by any route of exposure. Upon review, the Agency 
may permit reasonable variations in the placement of the first aid 
statement if a reference such as ``See first aid statement on back 
panel'' appears on the front panel. The first aid statement for 
products assigned to Toxicity Categories II or III may appear on any 
panel of the label.


Sec. 156.70   Precautionary statements for human hazards.

    (a) Requirement. Human hazard and precautionary statements as 
required must appear together on the label or labeling under the 
general heading ``Precautionary Statements'' and under appropriate 
subheadings similar to ``Humans and domestic animals,'' ``Environmental 
hazards'' (see subpart E of this part) and ``Physical or chemical 
hazards.'' The phrase ``and domestic animals'' may be omitted from the 
heading if domestic animals will not be exposed to the product.
    (b) Content of statements. When data or other information show that 
an acute hazard may exist to humans or domestic animals, the label must 
bear precautionary statements describing the particular hazard, the 
route(s) of exposure and the precautions to be taken to avoid accident, 
injury or toxic effect or to mitigate the effect. The precautionary 
paragraph must be immediately preceded by the appropriate signal word.
    (c) Typical precautionary statements. The table to this paragraph 
presents typical hazard and precautionary statements. Specific 
statements pertaining to the hazards of the product and its uses must 
be approved by the Agency. With Agency approval, statements may be 
augmented to reflect the hazards and precautions associated with the 
product as diluted for use. Refer to Sec. 156.68(b) for requirements 
for use dilution statements.

Sec. 156.78   Precautionary statements for physical or chemical 
hazards.

    (a) Requirement. Warning statements on the flammability or 
explosive characteristics of the pesticide product are required if a 
product meets the criteria in this section. Warning statements 
pertaining to other physical/chemical hazards (e.g., oxidizing 
potential, conductivity, chemical reactions leading to production of 
toxic substances) may be required on a case-by-case basis.

    (d) Total release fogger products. (1) A ``total release fogger'' 
is defined as a pesticide product in a pressurized container designed 
to automatically release the total contents in one operation, for the 
purpose of creating a permeating fog within a confined space to deliver 
the pesticide throughout the space.
    (2) If a pesticide product is at total release fogger containing a 
propellant with a flash point at or below 20  deg.F, then the following 
special instructions must be added to the ``Physical and Chemical 
Hazards'' warning statement, in addition to any flammability statement 
required by paragraph (b) of this section:

    This product contains a highly flammable ingredient. It may 
cause a fire or explosion if not used properly. Follow the 
Directions for Use on this label very carefully.

    (3) A graphic symbol depicting fire, such as illustrated in this 
paragraph, or an equivalent symbol, must be displayed along with the 
required language adjoining the ``Physical and Chemical Hazards'' 
warning statement. The graphic symbol must be no smaller than twice the 
size of the first character of the human hazard signal word.

Subpart E--Environmental Hazard and Precautionary Statements

Sec.
156.80    General.
156.85    Non-target organisms.
Subpart E--Environmental Hazard and Precautionary Statements


Sec. 156.80   General.

    (a) Requirement. Each product is required to bear hazard and 
precautionary statements for environmental hazards, including hazards 
to non-target organisms, as prescribed in this subpart. Hazard 
statements describe the type of hazard that may be present, while 
precautionary statements direct or inform the user of actions to take 
to avoid the hazard or mitigate its effects.
    (b) Location of statements. Environmental hazard and precautionary 
statements may appear on any panel of the label and may be

[[Page 50725]]

required also in supplemental labeling. The environmental hazard 
statements must appear together under the heading ``Environmental 
hazards.'' Typically the statements are grouped as a sub-category 
within the ``Precautionary Statements'' section of the labeling.
    (c) Type size. All environmental hazard and precautionary 
statements must be at least 6 point type.


Sec. 156.85   Non-target organisms.

    (a) Requirement. Where a hazard exists to non-target organisms, EPA 
may require precautionary statements of the nature of the hazard and 
the appropriate precautions to avoid potential accident, injury, or 
damage.
    (b) Examples. The statements in this paragraph illustrate the types 
of hazard statements that EPA may require and the circumstances under 
which they are typically required. These statements are not 
comprehensive; other statements may be required if more appropriate to 
the formulation or use.
    (1) If a pesticide intended for outdoor use contains an active 
ingredient with a mammalian acute oral LD50 of 100 mg/kg or 
less, the statement, ``This pesticide is toxic to wildlife'' is 
required.
    (2) If a pesticide intended for outdoor use contains an active 
ingredient with a fish acute LC50 of 1 ppm or less, the 
statement, ``This pesticide is toxic to fish'' is required.
    (3) If a pesticide intended for outdoor use contains an active 
ingredient with an avian acute oral LD50 of 100 mg/kg or 
less, or a subacute dietary LC50 of 500 ppm or less, the 
statement, ``This pesticide is toxic to wildlife'' is required.
    (4) If either accident history or field studies demonstrate that 
the use of the pesticide may result in fatality to birds, fish or 
mammals, the statement, ``This pesticide is extremely toxic to wildlife 
(fish)'' is required.
    (5) If a product is intended for or involves foliar application to 
agricultural crops, forests or shade trees, or mosquito abatement 
treatments, and contains a pesticide toxic to pollinating insects, the 
label must bear appropriate label cautions.
    (6) If a product is intended for outdoor use other than aquatic 
applications, the label must bear the caution, ``Keep out of lakes, 
ponds or streams. Do not contaminate water by cleaning of equipment or 
disposal of wastes.''

    Authority: 7 U.S.C. 136-136y.

Sec. 156.440   Scope and applicability.

    (a) Scope--(1) Performance standards. This subpart establishes 
performance standards for antimicrobial public health claims. The 
performance standards are based upon required efficacy testing for 
antimicrobial products specified in part 158 of this chapter. Test 
methods and standards, evaluation procedures and reporting standards 
referred to in this subpart are contained in the Pesticide Assessment 
Guidelines, Subdivision G. This subpart does not cover performance 
standards for non-public health claims.
    (2) Acceptable public health claim. This subpart describes public 
health claims that may be made on antimicrobial product labeling based 
upon efficacy performance standards. This subpart also establishes 
limitations on the use of certain claims, as well as specific 
antimicrobial claims that are not acceptable on product labeling. An 
antimicrobial public health product that does not meet the performance 
standard in this subpart for a public health claim may not bear that 
claim.
    (3) Use directions. This subpart describes certain use directions 
associated with public health claims, which are necessary to ensure 
that the product will achieve the level of antimicrobial performance 
claimed. This subpart does not set out use directions for non-public 
health antimicrobial products, nor does it describe comprehensively the 
use directions for public health products or claims, which are specific 
to the use sites and patterns. Additional detailed guidance on use 
directions for antimicrobial products is provided in the Pesticide 
Assessment Guidelines, Subdivision H.
    (b) Applicability. (1) This subpart applies to any antimicrobial 
product that is subject to the provisions of part 152, subpart W, and 
that makes a public health claim.
    (2) This subpart applies to end use antimicrobial products. This 
subpart does not apply to manufacturing use products.


Sec. 156.441   Definitions.

    Terms defined in FIFRA and part 152 of this chapter are used with 
the same definitions as given therein. In addition, the following terms 
are defined for the purposes of this subpart:
    Disinfectant means a substance that destroys or eliminates a 
specific species of infectious or other public health microorganism, 
but not necessarily bacterial spores, in the inanimate environment.
    Equivalent, when used with respect to a test protocol or method, 
means a test protocol or method, validated by multiple laboratory 
studies and approved by EPA, that accomplishes the purposes intended by 
the cited Guidelines test protocols, and that is expected to provide 
data of equal quality and completeness as data derived from testing 
according to an EPA Guideline protocol.
    Fungicide means a substance that destroys fungi (including yeasts) 
and fungal spores pathogenic to man or other animals in the inanimate 
environment.
    Guidelines means the Pesticide Assessment Guidelines, Subdivision G 
- Product Performance Test Guidelines, or the Harmonized OPPTS Test 
Guidelines, which are an updated, reformatted compilation of guidelines 
used for both pesticide and other chemical testing.
    Microbiological water purifier means any unit, water treatment 
product or system that removes, kills or inactivates all types of 
disease-causing microorganisms from the water, including bacteria, 
viruses and protozoan cysts, so as to render the treated water safe for 
drinking.
    Public health product means an antimicrobial product that bears a 
public health claim as defined in Sec. 156.443. A public health product 
is also a ``public health pesticide'' as defined by FIFRA section 
2(nn).
    Sanitizer means a substance that reduces the bacterial population 
in the inanimate environment by significant numbers, but does not 
destroy or eliminate all bacteria or other microorganisms.

[[Page 50726]]

    Sterilant means a substance that destroys or eliminates all forms 
of microbial life in the inanimate environment, including all forms of 
vegetative bacteria, bacterial spores, fungi, fungal spores, and 
viruses. For purposes of this subpart, ``sporicide'' and ``sterilant'' 
are synonymous.
    Tuberculocide means a substance that destroys or irreversibly 
inactivates tubercle bacilli in the inanimate environment.
    Virucide means a substance that destroys or inactivates viruses in 
the inanimate environment.


Sec. 156.442   Use of terms and statements on labeling.

    When this subpart authorizes the use of a term on product labeling, 
other grammatical variants, phrases and statements having the same or 
equivalent connotation are also authorized, unless EPA, on a case-by-
case basis, prohibits their use. For example, authorization to use the 
term ``sterilant'' also means that ``sterilizer,'' ``sterilization,'' 
and similar terms may be used. EPA approves the content of each label, 
and may, in its discretion, limit the use of certain terms, phrases or 
statements.


Sec. 156.443   Public health claims.

    EPA will consider a product to make a public health claim if any of 
the following applies:
    (a) A claim is made for control of specific microorganisms or 
classes of microorganisms that are directly or indirectly infectious or 
pathogenic to man (or both man and animals). Examples of specific 
microorganisms include Mycobacterium tuberculosis, Pseudomonas 
aeruginosa, E. coli, HIV, Streptococcus, and Staphylococcus aureus. 
Claims for control of microorganisms infectious or pathogenic only to 
animals (such as canine distemper virus or hog cholera virus) are not 
considered public health claims.
    (b) A claim is made for the product as a sterilant, disinfectant, 
virucide, or sanitizer, regardless of the site of use of the product, 
and regardless of whether specific microorganisms are identified.
    (c) A claim is made for the product as a fungicide against fungi 
infectious or pathogenic to man, or the product does not clearly 
indicate it is intended for use only against non-public health fungi.
    (d) A claim is made for the product as a microbiological water 
purifier (see Sec. 156.457).
    (e) A non-specific claim is made that the product will beneficially 
impact or affect public health at the site of use or in the environment 
in which applied (such as a ``sanitary'' claim), and:
    (1) The product contains one or more ingredients that, under the 
criteria in 40 CFR 153.125(a), is considered an active ingredient with 
respect to a public health microorganism and there is no other 
functional purpose for the ingredient in the product; or
    (2) The product is similar in composition to registered products 
that make explicit antimicrobial public health claims.


Sec. 156.444   Unacceptable statements and claims.

    No pesticide or device, including an antimicrobial pesticide 
product, may bear false or misleading claims or statements (including 
the name of the product). Claims or statements of the type identified 
in this section are deemed to be false or misleading and are not 
acceptable on antimicrobial product labeling. Effective on [date 
certain - 1 year], EPA will regard an antimicrobial product bearing a 
statement, claim, or product name that is unacceptable under this 
section to be misbranded under FIFRA section 2(q).
    (a) Statements or claims that suggest or imply greater 
effectiveness because of composition, e.g., ``hospital'' strength or 
grade, ``industrial strength,'' ``extra strength.''
    (b) Statements or claims that suggest or imply that the product can 
or will prevent or control disease or offer health protection. Claims 
such as ``prevents infection,'' ``controls infection'' or ``prevents 
cross-infection'' or that the product will control or mitigate any 
disease (such as Legionnaire's disease), infection, or pathological 
condition constitute drug claims regulated by the Food and Drug 
Administration. A claim that the product ``controls cross-contamination 
from treated surfaces,'' or ``kills [name of specific organism] in the 
inanimate environment'' is acceptable.
    (c) Statements or claims that are overly broad, non-specific, 
ambiguous or exaggerated.
    (1) The terms ``microbicide'' and ``microbistat'' are not 
acceptable on a public health product. If used on a non-public health 
product, the claim must be qualified to indicate that the product does 
not provide public health protection.
    (2) The term ``biocide'' is unacceptable on a public health product 
because it implies that the product can kill all living organisms, 
including plants and animals. If used on a non-public health product, 
the term must be qualified by directions for use or other statements 
that make clear the types of organisms to be controlled.
    (3) The term ``antibacterial'' or ``germicidal'' is not acceptable 
on a non-public health product. If used on a public health product, the 
labeling must identify the specific organisms to be controlled.
    (4) The term ``antimicrobial'' is not acceptable on a non-public 
health product, unless clearly and properly qualified to indicate that 
the product does not provide public health protection. ``Clearly and 
properly qualified'' means, at a minimum, that:
    (i) The term ``antimicrobial'' is clearly associated with, and in 
close proximity to, its qualifying statement on the labeling. It is 
always unacceptable for the term ``antimicrobial'' to appear on a 
different label panel from its qualifying statement.
    (ii) The term ``antimicrobial'' is not highlighted or given 
prominence over the qualifying statement by means of placement or 
presentation (e.g., type size, style, color or contrast).
    (iii) The term ``antimicrobial'' is not part of the product name.
    (5) The prefix ``steri-'' implies sterilant activity, and may not 
be used in the product name or on a product that is not a sterilant.
    (6) Statements or claims implying indefinite or all-encompassing 
antimicrobial protection against bacteria, fungi or algae (``germ-
free,'' ``mildew-proof,'' ``algae-free'') are not acceptable.
    (d) Claims or statements that differ from or do not accurately 
reflect the results demonstrated by testing.
    (1) Product names, or claims or statements expressing or implying a 
higher level of antimicrobial activity than that demonstrated by 
testing, even if qualified (for example, ``sterisure bacteriostat''). 
The labeling must unambiguously identify the level of antimicrobial 
activity (disinfectant, sanitizer, etc).
    (2) Claims or statements that are inconsistent with conditions of 
efficacy established by testing (e.g., a claim of efficacy within 30 
seconds, when testing and use directions require 2 minutes contact time 
for efficacy.)
    (e) Statements or claims of efficacy based on unsubstantiated, 
improbable or irrelevant site/pest relationships. For example, a claim 
of efficacy against a pest not likely to occur on the site (e.g., 
athlete's foot fungi in toilet bowls) is misleading.
    (f) A statement or claim of presumptive or screening efficacy, even 
if qualified, is not acceptable on an end use product. Presumptive 
efficacy testing is intended to demonstrate that an active ingredient 
is capable of antimicrobial efficacy, but such testing is not conducted 
under specific conditions of use. An end use product

[[Page 50727]]

must be tested for, demonstrate, and be labeled for a specific level of 
antimicrobial efficacy against identified organisms under conditions of 
use likely to be encountered.
    (1) Legionnaire's disease claims in cooling tower water are not 
acceptable. Express or implied claims that a product will prevent 
growth or spread of Legionnaire's Disease bacteria (LDB) are 
unacceptable. Product labeling may provide accurate information 
concerning current knowledge and recommendations of the Public Health 
Service, or laboratory test data showing presumptive effectiveness of 
the product against pure cultures of LDB. Such information must be 
qualified by statements to the effect that findings are presumptive, 
and that there is no evidence that chemical treatment will control LDB 
growth under actual use conditions, reduce transmission of LDB, or 
prevent Legionnaire's Disease.
    (2) No statement of phenol coefficient may appear on a public 
health end use product. The phenol coefficient is a calculated 
comparison of presumptive efficacy.
    (g) Certain symbols, icons, or graphics are unacceptable.
    (1) The caduceus symbol is not acceptable because it is a medical 
symbol that implies endorsement by the medical profession or broad 
medical significance or health protection that is not acceptable in 
accordance with paragraph (b) of this section.
    (2) The name and symbol of the Red Cross are not permitted on any 
product.


Sec. 156.445   Sterilant claim on hard surfaces.

    (a) Performance standard. (1) When tested in accordance with the 
test methods and standards in OPPTS 810.2100(b)(1) and (2) of the 
guidelines or its equivalent, the product kills all test spores on all 
carriers with no failures; and
    (2) When tested by a laboratory independent of the registrant in 
accordance with the test methods and standards in OPPTS 810.2100(b)(4) 
of the guidelines or its equivalent, the product kills all test spores 
on all carriers with no failures.
    (b) Acceptable claim. (1) A product that meets the performance 
standard in paragraph (a) may bear ``sterilant'' claims or variants of 
these.
    (2) Since a sterilizer by definition destroys or eliminates all 
forms of microbial life, a sterilant product may bear claims of any 
lesser efficacy levels, such as disinfectant, bactericidal, 
tuberculocidal, fungicidal, virucidal or sanitizer. Separate directions 
for use must be provided for each lesser level of antimicrobial 
activity.
    (c) Unacceptable claims. (1) Liquid chemical germicides may not 
make sterilant claims for critical or semi-critical medical devices. 
Claims for liquid chemical germicides are limited to pre-cleaning 
critical or semi-critical medical devices prior to sterilization.
    (2) ``One-step'' claims are not allowed for sterilants. The label 
must require pre-cleaning of surfaces prior to sterilization.


Sec. 156.446   Disinfectant claim on hard surfaces.

    (a) Performance standard. (1) When tested in accordance with the 
test methods and standards in OPPTS 810.2100(c), (d), or (e) of the 
guidelines or its equivalent, the product kills the test microorganisms 
on 59 out of each set of 60 carriers/slides. Although the performance 
standard is the same for all disinfectant claims, the test standards 
and test microorganisms define the level of disinfectant claim that may 
be made on product labeling.
    (2) An applicant who wishes to make disinfectant claims for 
additional microorganisms not designated in the test methods and 
standards may do so based upon efficacy tests conducted with those 
additional microorganisms. When tested in accordance with the test 
methods and standards in OPPTS 810.2100(k) of the guidelines or its 
equivalent, for each organism the product must kill all test organisms 
on 10 carriers for each of two samples representing two different 
batches.
    (b) Acceptable limited disinfectant claim--(1) Products containing 
pine oil. A product containing pine oil (as sole active ingredient or 
in combination with other ingredients) and that meets the performance 
standard in paragraph (a) when tested using the test standards in OPPTS 
810.2100(c) of the guidelines or its equivalent and the test 
microorganism Salmonella cholerasuis may bear only a claim as a 
``limited disinfectant against bacteria of intestinal origin.''
    (2) All other products. A product that meets the performance 
standard in paragraph (a) of this section for only one major group of 
microorganisms (Gram negative or Gram positive bacteria) when tested 
using the test standards of OPPTS 810.2100(c) of the guidelines or its 
equivalent may bear only a claim as a ``limited disinfectant.'' The 
product labeling must identify the specific organisms against which the 
product is effective.
    (c) Acceptable general or broad spectrum disinfectant claim. A 
product that meets the performance standard in paragraph (a) of this 
section for both Gram negative and Gram positive bacteria when tested 
using the test standards of OPPTS 810.2100(d) of the guidelines or its 
equivalent may bear a claim as a ``general or broad spectrum 
disinfectant,'' and may also bear a claim as a ``hard food contact 
surface disinfectant.'' The product labeling must identify the specific 
organisms against which the product is effective.
    (d) Acceptable hospital or medical disinfectant claim. A product 
that meets the performance standard in paragraph (a) of this section 
when tested in accordance with the test standard in OPPTS 810.2100(e) 
of the guidelines or its equivalent may bear a claim as a ``hospital or 
medical environment disinfectant,'' and may also bear a claim as a 
``hard food contact surface disinfectant.'' The product labeling must 
identify the specific organisms against which the product is effective.
    (e) Towelette disinfectant claims--(1) Single use towelette. A 
single use towelette may bear a claim as a ``single use towelette for 
the disinfection of hard surfaces'' if, when tested by methods and 
standards approved by EPA (OPPTS 810.2100(i)(1)(i) of the guidelines or 
its equivalent), it meets the performance standard in OPPTS 
810.2100(i)(3)(i) of the guidelines or its equivalent.
    (2) Multiple use towelettes. A multiple use towelette may bear a 
claim as a ``multiple use towelette for the disinfection of hard 
surfaces'' if, when tested by the methods and standards approved by EPA 
(OPPTS 810.2100(i)(1)(ii) of the guidelines or its equivalent), it 
meets the performance standard in OPPTS 810.2100(i)(3)(ii) of the 
guidelines or its equivalent.
    (f) Unacceptable claims. (1) A product that functions by fogging 
may not bear claims of disinfection for duct systems, air, or room 
surfaces.
    (2) Products with circulate-in-place (CIP) applications may not 
bear claims of disinfection because CIP application has not been shown 
to be effective in disinfecting duct systems, air or room surfaces. CIP 
products may, however, bear claims of sanitization if they meet the 
performance standard of Sec. 156.451.


Sec. 156.447   Fungicidal claim on hard surfaces.

    (a) Performance standard. (1) The product meets the performance 
standard of OPPTS 810.2100(d) of the guidelines or its equivalent as a

    (i) Inactivates virus at all dilutions when cytotoxicity is not 
observed in the assay system, or at all dilutions above the cytotoxic 
level when cytotoxicity is observed; and
    (ii) Achieves at least a 99.9% (3-log) reduction in viral titer in 
all samples when cytotoxicity is present.
    (b) Acceptable claim--(1) Combination disinfectant/virucidal 
products. A disinfectant product that also meets the performance 
standard in paragraph (a) of this section may also bear a claim of 
effectiveness as a ``virucide'' or as ``virucidal.'' The product 
labeling must identify the specific viruses against which the product 
is effective.
    (2) Virucide only products. A product that meets the performance 
standard in paragraph (a) of this section, but is not a disinfectant, 
may bear only a limited claim of effectiveness against viruses 
specifically tested against, and must bear a disclaimer that the 
product is not a disinfectant.
    (3) HIV/HBV claims. A claim for virucidal activity against HIV-1, 
HIV-2, or hepatitis B (HBV) viruses may be made only for use sites that 
involve human health care or other sites where there is a likelihood of 
soiling of inanimate surfaces or objects with blood or body fluids.
