## 90 40 CFR Ch. I (7–1–11 Edition) § 158.5

are used with the meaning given in the Act. Applicable terms from the Federal Food, Drug, and Cosmetic Act also apply to this part. Individual subparts may contain definitions that pertain solely to that subpart. The following additional terms apply to this part:

Applicant means any person or entity, including for the purposes of thispart a registrant, who submits, or is required to submit, to the Agency anyapplication, petition, or submission intended to persuade EPA to grant, modify, or leave unmodified a registrationor other approval required as a condition of sale or distribution of a pesticide. Such submissions may include, but are not limited to, the following:

(1) An application for registration or amended registration of a pesticide product under FIFRA sec. 3 or 24.

(2) A submission of data required in conjunction with reregistration of a currently registered product under FIFRA sec. 4.

(3) An application for an experimental use permit under FIFRA sec. 5.

(4) A submission of data in response to a notice issued by EPA under FIFRA sec. 3(c)(2)(B).

(5) A petition to establish or modify a tolerance or an exemption from therequirement of a tolerance for a pesticide chemical residue under FFDCA sec. 408.

Registration includes a new registration, amended registration and reregistration, unless stated otherwise.
§ 158.5 Applicability.

(a) The requirements of this part apply to the following submissions:

(1) An application for new or amended registration under FIFRA sec. 3 or 24.

(2) An application for experimental use permit under FIFRA sec. 5.

§ 158.30 Flexibility.

(a) FIFRA provides EPA flexibility torequire, or not require, data and information for the purposes of making regulatory judgments for pesticide products. EPA has the authority to establish or modify data needs for individual pesticide chemicals. The actual datarequired may be modified on an individual basis to fully characterize the use and properties, characteristics, or effects of specific pesticide products under review. The Agency encourages each applicant to consult with EPA todiscuss the data requirements particular to its product prior to and during the registration process.

(b) The Agency cautions applicants that the data routinely required in this part may not be sufficient to permit EPA to evaluate the potential of the product to cause unreasonable adverse effects to man or the environment.EPA may require the submission of additional data or information beyond that specified in this part if such dataor information are needed to appropriately evaluate a pesticide product.

(c) This part will be updated as needed to reflect evolving program needs and advances in science.

§ 158.32 Format of data submissions.

(a) General . (1) All data submitted under this part must be formatted in accordance with this section.

(2) The requirements of this sectiondo not apply to administrative materials accompanying a data submission,including forms, labeling, and correspondence.

(b) Transmittal document . Each submission in support of a regulatory action must be accompanied by a transmittal document, which includes:

(1) Identity of the submitter. (2) The transmittal date. (3) Identification of the regulatoryaction with which the submission is associated, e.g., the registration or petition number.

§ 158.33 Confidential data.

(a) Definitions . For the purposes of this section:

(1) Registered or previously registered pesticide means any pesticide containing an active ingredient contained in a product that is, or has ever been,an active ingredient in a product registered under sec. 3 of FIFRA. A registered pesticide that is the subject ofan application for a new use falls within the category of ‘‘registered or previously registered pesticide.’’ (2) Safety and efficacy informationmeans information concerning the objectives, methodology, results, or significance of any test or experiment performed on or with a registered or previously registered pesticide or its separate ingredients, impurities, ordegradation products, and any information concerning the effects of such pesticide on any organism or the behavior of such pesticide in the environment, including, but not limited to, data on safety to fish and wildlife, humans and other mammals, plants, animals, and soil, and studies on persistence,translocation and fate in the environment, and metabolism.

(b) Applicability . (1) This section applies to information submitted pursuant to this part. It supplements the general confidentiality procedures in 40 CFR part 2, subpart B, including FIFRA confidentiality procedures at 40CFR 2.307. To the extent that provisions in this section conflict with thosein 40 CFR part 2, subpart B, the provisions in this section take precedence. The provisions of 40 CFR 2.308 do notapply to information to which this section applies. In addition to complying with the requirements of this section,any confidentiality claims for information subject to 40 CFR part 174 (plantincorporated protectants) must be substantiated at the time of submission as described in §174.9 of this chapter.

(2) FFDCA sec. 408(i) protects confidential information submitted in connection with an application for a tolerance or exemption to the same extent as FIFRA sec. 10. References in this section to FIFRA sec. 10 are deemed to apply equally to information submitted pursuant to FFDCA sec. 408, pursuant to the authority in sec. 408(i).

(c) Method of asserting business confidentiality claims —(1) Claim required . Information to which this section applies (and which is submitted on or after the effective date of this regulation) willbe deemed as not subject to a confidentiality claim unless a claim for that information is made in accordance withthe procedures specified in this paragraph. Information not subject to a confidentiality claim may be made available to the public without further notice, subject to the requirements of FIFRA sec. 10(g).


## 92 40 CFR Ch. I (7–1–11 Edition) § 158.33

(2) Statement required . Upon submission to EPA, each document must be accompanied by a signed and dateddocument containing either the statements in paragraph (c)(2)(i) or (ii) of this section.

### (2) Study meets or exceeds criteria. I have applied the criteria of 40 CFR 158.34for flagging studies for potential adverse effects to the results of the attached study. This study meets or exceeds the criteria numbered [insert all applicable reporting codes].



### § 158.45 Waivers.

(a) The data requirements specified in this part as applicable to a categoryof products will not always be appropriate for every product in that category. Some products may have unusual physical, chemical, or biological properties or atypical use patternswhich would make particular data requirements inappropriate, either because it would not be possible to generate the required data or because thedata would not be useful in the Agency’s evaluation of the risks or benefits of the product. The Agency will waivedata requirements it finds are inappropriate, but will ensure that sufficientdata are available to make the determinations required by the applicable statutory standards.

(b)(1) Applicants are encouraged to discuss a data waiver request with theAgency before developing and submitting supporting data, information, or other materials.

(2) All waiver requests must be submitted to the Agency in writing. The request must clearly identify the data requirement(s) for which a waiver is sought along with an explanation and supporting rationale why the applicant believes the data requirement should be waived. In addition, the applicantmust describe any unsuccessful attempts to generate the required data, furnish any other information whichthe applicant(s) believe(s) would support the request, and when appropriate, suggest alternative means of obtaining data to address the concern which underlies the data requirement.

(c) The Agency will review eachwaiver request and subsequently inform the applicant in writing of its decision. If the decision could apply to more than the requested product, the Agency, in its discretion, may choose to send a notice to all registrants or publish a notice in the F EDERAL

§ 158.60 Minor use data policies.

FIFRA sec. 2(ll) defines the term ‘‘minor use’’and FIFRA provides anumber of statutory provisions concerning minor uses. In addition, EPA has established policies with respect to minor uses of pesticides, including, but not limited to, the following:

(a) A new data requirement pertinent to both an unregistered minor use anda registered major use will not be applied to a minor use applicant until itis applied to the major use registration.

(b) EPA will accept appropriate and adequate extrapolations and regionaldata to support establishment of individual minor use tolerances.

§ 158.70 Satisfying data requirements.

(a) General policy . The Agency will determine whether the data submittedor cited to fulfill the data requirements specified in this part are acceptable. This determination will be basedon the design and conduct of the experiment from which the data were derived, and an evaluation of whether the data fulfill the purpose(s) of the datarequirement. In evaluating experimental design, the Agency will consider whether generally accepted methods were used, sufficient numbers of measurements were made to achieve statistical reliability, and sufficient controls were built into all phases ofthe experiment. The Agency will evaluate the conduct of each experiment interms of whether the study was conducted in conformance with the design,good laboratory practices were observed, and results were reproducible. The Agency will not reject data merely because they were derived from studieswhich, when initiated, were in accordance with an Agency-recommendedprotocol, even if the Agency subsequently recommends a different protocol, as long as the data fulfill thepurposes of the requirements as described in this paragraph.

(1) The provisions in this part 158 should be read in conjunction with the


## 95 Environmental Protection Agency § 158.80

provisions in §152.85 to claim eligibility for the formulators’ exemption.

(2) [Reserved] (b) Good laboratory practices . Applicants must adhere to the good laboratory practice (GLP) standards described in 40 CFR part 160 when conducting studies. Applicants must alsoadhere to GLP standards when conducting a study in support of a waiver request of any data requirement whichis within the scope of the GLP requirements.

(c) Agency guidelines . EPA has published Test Guidelines that contain standards for conducting acceptable tests, guidance on the evaluation and reporting of data, definition of terms, and suggested study protocols. Copies of the Test Guidelines may be obtained by visiting the agency’s website at www.epa.gov/pesticides

.

(d) Study protocols —(1) General . Any appropriate protocol may be used to generate the data required by this part, provided that it meets the purpose ofthe test standards specified in the pesticide assessment guidelines, and provides data of suitable quality and completeness as typified by the protocols cited in the guidelines. Applicants should use the test procedure which ismost suitable for evaluation of the particular ingredient, mixture, or product.Accordingly, failure to follow a suggested protocol will not invalidate atest if another appropriate methodology is used.

(2) Organization for Economic Co-Operation and Development (OECD) protocols

. Tests conducted in accordance with the requirements and recommendations of the applicable OECD protocols can be used to develop data necessary to meet the requirements specified in this part. Applicants should note, however, that certain of the OECD recommended teststandards, such as test duration and selection of test species, are less restrictive than those recommended by EPA. Therefore, when using OECD protocols, care should be taken to observe the test standards in a manner such that the data generated by the study will satisfy the requirements of this part.

(e) Combining studies . Certain toxicology studies may be combined to satisfy data requirements. For example, carcinogenicity studies in rats may be combined with the rat chronic toxicity study. Combining appropriate studies may be expected to reduce usage of test animals as well as reduce the cost of studies. EPA encourages this practice by including standards for acceptablecombined tests in the Pesticide Assessment Guidelines. Registrants and applicants are encouraged to consider combining other tests when practicaland likely to produce scientifically acceptable results. Registrants and applicants, however, must consult with theEPA before initiating combined studies.
§ 158.75 Requirements for additional data. The data routinely required by this part may not be sufficient to permitEPA to evaluate every pesticide product. If the information required under this part is not sufficient to evaluate the potential of the product to cause unreasonable adverse effects on man orthe environment, additional data requirements will be imposed. However,EPA expects that the information required by this part will be adequate in most cases for an assessment of the properties and effects of the pesticide.

§ 158.80 Use of other data.

(a) Data developed in foreign countries

. With certain exceptions, laboratory and field study data developed outside the United States may be submitted in support of a pesticide registration. Data generated in a foreign countrywhich the Agency will not consider include, but are not limited to, data from tests which involved field test sites or a test material, such as a native soil,plant, or animal, that is not characteristic of the United States. Applicants submitting foreign data musttake steps to ensure that U.S. materials are used, or be prepared to supply data or information to demonstrate thelack of substantial or relevant differences between the selected material or test site and the U.S. material or test site. Once submitted, the Agency will determine whether or not the data meet the data requirements.

(b) Data generated for other purposes

. Data developed for purposes other thansatisfaction of FIFRA data requirements, such as monitoring studies,


## 96 40 CFR Ch. I (7–1–11 Edition) § 158.100

may also satisfy data requirements inthis part. Consultation with the Agency should be arranged if applicants are unsure about suitability of such data.


## Subpart B—How To Use Data Tables

§ 158.100 Pesticide use patterns.

(a) General use patterns . There are six broad use categories used in the data tables. The six broad categories includeterrestrial outdoor uses, aquatic outdoor uses, greenhouse uses, forestryuses, residential outdoor uses, and indoor uses of all types. The 6 broad use categories are further subdivided into 12 general use patterns which are the bases for data requirements established by use pattern. Within the data tables,general use patterns have been combined into single columns when the data requirements are the same for thecombined uses. If there are no data requirements for a specific use, the column for that use is not included in the table. The 12 general use pattern groups used in the data table in this part are:

(1) Terrestrial food crop use. (2) Terrestrial feed crop use. (3) Terrestrial nonfood crop use. (4) Aquatic food crop use. (5) Aquatic nonfood use. (6) Greenhouse food crop use. (7) Greenhouse nonfood crop use. (8) Forestry use. (9) Residential outdoor use. (10) Residential indoor use. (11) Indoor food use. (12) Indoor nonfood use. (b) Pesticide use site index . The Pesticide Use Site Index is a comprehensive list of specific pesticide use sites. The index is alphabetized separately bysite for all agricultural and all nonagricultural uses. The Pesticide Use Site Index associates each pesticide use site with one or more of the 12 generaluse patterns. It may be used in conjunction with the data tables to determine the applicability of data requirements to specific uses. The Pesticide Use Site Index, which will be updated periodically, is available from the Agency or may be obtained from the Agency’s website at http://www.epa.gov/ pesticides

. (c) Applicants unsure of the correct use pattern for their particular product should consult the Agency.
§ 158.110 Required and conditionally required data. The tables in this part use thedescriptors R (required), CR (conditionally required), and NR (not required) as a general indication of the applicability of a data requirement. In all cases, the test notes referred to inthe table must be consulted to determine the actual applicability of the data requirement.

(a) EPA requires data designated as ‘‘required’’(R) for products with a given use pattern in order to evaluate the risks or benefits of a product having that use pattern under any conditions established by the test notes.

(b) Data designated as ‘‘conditionally required’’ (CR) for products with a given use pattern are required by EPA to evaluate the risks or benefits of a product having that use pattern if the product meets the conditions specifiedin the notes accompanying the requirement. The determination of whether the data must be submitted is based on the product’s use pattern, physical or chemical properties, expected exposure of nontarget organisms, and/or results of previous testing (for example, tier testing). Applicants must evaluateeach applicable test note for the conditions and criteria to be considered indetermining whether conditionally required data must be submitted.

(c) Data not required for the Agency’s assessment of the risks and benefits of a particular use pattern are designated ‘‘not required’’ (NR) in data tables.

§ 158.120 Determining data requirements. As with current practice, the actualdata and studies required may be modified on an individual basis to fully characterize the use and properties ofspecific pesticide products under review. While EPA is attempting to assist the applicant in this subpart, it is important to emphasize that it is the applicant’s obligation under FIFRA to demonstrate that an individual product meets the standard under FIFRA and/ or FFDCA. Accordingly, applicants are


## 97 Environmental Protection Agency § 158.130

encouraged to consult with the Agency on the appropriate data requirements as set forth here as they relate to their specific product prior to and during the registration process.

(a) Finding the appropriate data table

.(1) Pesticide data requirements for conventional chemical active ingredients and related substances are presented in subparts D, E, F, G, K, L, N, and O of this part in the form of a series of datatables, each addressing a particular scientific discipline or data topic. Datarequirements for biochemical and microbial pest control agents are contained and are described separately within subparts U and V of this part, respectively.

(2) Key to table notations. R = required data; CR = conditionally required data; NR = Not required; MP =manufacturing-use product; EP = enduse product; TEP = typical end-use product; TGAI = technical grade of theactive ingredient; PAI = pure active ingredient; PAIRA = pure active ingredient, radiolabeled; Choice = choice of several test substances depending on studies required.

(b) Identifying required studies . To determine the specific kinds of data needed to support the registration use of each pesticide product, the applicant
may:

(1) Refer to the applicable subpart(s) of this part. These subparts describe the data requirements including data tables for each subject area.

(2) Select the general use pattern(s)that best cover the use pattern(s) specified on the pesticide product label as explained in §158.100. All applicable use patterns must be included.

(3) Proceed down the appropriate general use pattern column in the table and note which tests are required (R),conditionally required (CR), or not required (NR). Required and conditionally required studies are described in §158.110.

(4) Review the notes for each requirement to determine its applicability tothe specific product proposed for registration.

(5)(i) Proceed down the Test substance columns and determine the appropriate test substance needed for that study. If the data are intended to support a manufacturing-use product, use the MP column. If the data are intended to support an end-use product, use the EP column.

(ii) The test substances columns specify which substance is to be used for testing. Applicants should note that the substance that must be used when performing the study may or may not be the product itself. For example, the data from a certain study may be required to support the registration ofan end-use product, but the test substance column may state that the particular test shall be performed usingthe technical grade of the active ingredient(s) in the end-use product.

(iii) Manufacturing-use products(MP) and end-use products (EP) containing a single active ingredient andno intentionally added inert ingredients are considered identical in composition to each other, and to the technical grade of the active ingredient (TGAI) from which they were derived.Therefore, the data from a test conducted using any one of these as the test substance is also suitable to meet the requirement (if any) for the same test to be conducted using either of the other substances.

(6) Refer to the Pesticide Assessment Guideline reference number for each study located in the first column. See §158.70(c) for information pertaining tothe guidelines and how to obtain copies.

§ 158.130 Purposes of the registration data requirements. (a) General . The data requirementsfor registration are intended to generate data and information necessary to address concerns pertaining to theidentity, composition, potential adverse effects and environmental fate of each pesticide.

(b) Product chemistry —(1) Product composition . Data on product composition are needed:

(i) To support the conclusions expressed in the statement of formula;

(ii) To compare to the composition of materials used in required testing under this part; and

(iii) To determine whether a productis ‘‘identical or substantially similar’’to another product, a determination that involves the comparison of product composition.


## 98 40 CFR Ch. I (7–1–11 Edition) § 158.130

(2) Nominal concentration and certified limits . The nominal concentration of a product, defined as that concentration that is expected to be present in a product as a result of the production or formulation process, is used to gaugethe acceptability of the certified limits, which define the outer limits of the range of the product’s ingredients. The certified limits are used to enforce thecomposition of the product and to ensure the accuracy of hazard assessments.

(3) Physical and chemical characteristics . The physical and chemical characteristics of an active ingredient or product are used:

(i) To confirm or provide supportiveinformation on the identity and composition of the product;

(ii) To assess the hazards of the ingredient or product; and

(iii) To trigger or evaluate certain other studies required by this part.

(c) Product performance . Requirements to develop data on product performance provide a mechanism to ensure that pesticide products will perform as intended and that unnecessary pesticide exposure to the environment will not occur as a result of the use ofineffective products. Specific performance standards are used to validate the efficacy data in the public health areas, including disinfectants used to control microorganisms infectious toman in any area of the inanimate environment and those pesticides used to control vertebrates (such as rodents,birds, bats and skunks) that may directly or indirectly transmit diseases to humans.

(d) Toxicology-humans and domestic animals . Data required to assess hazards to humans and domestic animals are derived from a variety of acute, subchronic and chronic toxicity tests, and tests to assess mutagenicity and pesticide metabolism.

(1) Acute studies . Determination ofacute oral, dermal and inhalation toxicity is usually the initial step in the assessment and evaluation of the toxic characteristics of a pesticide. These data provide information on health hazards likely to arise soon after, and as a result of, short-term exposure. Data from acute studies serve as abasis for classification and precautionary labeling. For example,acute toxicity data are used to calculate farmworker reentry intervals and to develop precautionary label statements pertaining to protective clothing requirements for applicators. They also provide information used in establishing the appropriate dose levelsin subchronic and other studies; provide initial information on the mode oftoxic action(s) of a substance; and determine the need for child resistant packaging. Information derived fromprimary eye and primary dermal irritation studies serves to identify possiblehazards from exposure of the eyes, associated mucous membranes and skin.

(2) Subchronic studies . Subchronic tests provide information on health hazards that may arise from repeated exposures over a limited period oftime. They provide information on target organs and accumulation potential.The resulting data are also useful in selecting dose levels for chronic studies and for establishing safety criteria for human exposure. These tests are not capable of detecting those effects thathave a long latency period for expression (e.g., carcinogenicity).

(3) Chronic studies . Chronic toxicity studies (usually conducted by feeding the test substance to the test species) are intended to determine the effects of a substance in a mammalian speciesfollowing prolonged and repeated exposure. Under the conditions of this test,effects which have a long latency period or are cumulative should be detected. The purpose of long-term carcinogenicity studies is to observe test animals over most of their life span for the development of neoplastic lesions during or after exposure to variousdoses of a test substance by an appropriate route of administration.

(4) Developmental toxicity and reproduction studies . The developmental toxicity study is designed to determine the potential of the test substance toinduce structural and/or other abnormalities to the fetus as the result ofexposure of the mother during pregnancy. Two-generation reproductiontesting is designed to provide information concerning the general effects of a test substance on gonadal function,estrus cycles, mating behavior, conception, parturition, lactation, weaning,


## 99 Environmental Protection Agency § 158.130

and the growth and development of the offspring. The study may also provide information about the effects of the test substance on neonatal morbidity, mortality, and preliminary data on prenatal developmental toxicity and serve as a guide for subsequent tests.

(5) Mutagenicity studies . For each test substance a battery of tests is required to assess the potential to affect the mammalian cell’s genetic components. The objectives underlying the selection of a battery of tests for mutagenicity assessment are:

(i) To detect, with sensitive assay methods, the capacity of a chemical to alter genetic material in cells.

(ii) To determine the relevance of these mutagenic changes to mammals.

(iii) When mutagenic potential is demonstrated, to incorporate these findings in the assessment of heritable effects, carcinogenicity, and, possibly, other health effects.

(6) Metabolism studies . Data from studies on the absorption, distribution,metabolism, and excretion of a pesticide aid in the valuation of test results from other toxicity studies and in the extrapolation of data from animalsto man. The main purpose of metabolism studies is to produce data which increases the Agency’s understanding of the behavior of the chemical whenconsidering the human exposure anticipated from intended uses of the pesticide.

(e) Hazards to nontarget organisms —(1) General . The information required to assess hazards to nontarget organismsis derived from tests to determine pesticidal effects on birds, mammals, fish, terrestrial and aquatic invertebratesand plants. These tests include shortterm acute, subacute, reproduction, simulated field, and full field studiesarranged in a hierarchical or tier system which progresses from the basic laboratory tests to the applied field tests. The results of each tier of testingmust be evaluated to determine the potential of the pesticide to cause adverse effects, and to determine whether further testing is required. A purpose common to all data requirements is to provide data which determine the needfor (and appropriate wording for) precautionary label statements to minimize the potential adverse effects to nontarget organisms.

(2) Short-term studies . The short-termacute and subchronic laboratory studies provide basic toxicity information which serves as a starting point for the hazard assessment. These data are used: To establish acute toxicity levelsof the active ingredient to the test organisms; to compare toxicity information with measured or estimated pesticide residues in the environment in order to assess potential impacts onfish, wildlife and other nontarget organisms; and to indicate whether further laboratory and/or field studies are needed.

(3) Long-term and field studies . Additional studies ( i.e. , avian, fish, and invertebrate reproduction, life cycle studies and plant field studies) may berequired when basic data and environmental conditions suggest possible problems. Data from these studies are used to: Estimate the potential for chronic effects, taking into account the measured or estimated residues in the environment; and to determine if additional field or laboratory data are necessary to further evaluate hazards. Simulated field and/or field data areused to examine acute and chronic adverse effects on captive or monitoredfish and wildlife populations under natural or near-natural environments. Such studies are required only whenpredictions as to possible adverse effects in less extensive studies cannotbe made, or when the potential for adverse effects is high.

(f) Applicator and post-application exposure. Data are used to evaluate exposures to persons in occupational and non-occupational settings, including agricultural, residential, commercial, institutional and recreational sites.Data include oral, dermal and inhalation exposure data, post-applicationresidue data, post-application monitoring data, use information, and human activity information. These data, together with toxicology data,are used to determine whether application or post-application risks are ofconcern, and, where appropriate, to develop post-application restrictions such as reentry restrictions.

(g) Pesticide spray drift evaluation

. Data required to evaluate pesticide


## 100 40 CFR Ch. I (7–1–11 Edition) § 158.130

spray drift are derived from studies of droplet size spectrum and spray driftfield evaluations. These data contribute to the development of the overall exposure estimate and, along with data on toxicity for humans, fish and wildlife, or plants, are used to assess the potential hazard of pesticides to these organisms. A purpose common to all these tests is to provide data which will be used to determine the need for(and appropriate wording for) precautionary labeling to minimize the potential adverse effect to nontarget organisms.

(h) Environmental fate —(1) General

. The data generated by environmentalfate studies are used to: Assess the toxicity to man through exposure of humans to pesticide residues remainingafter application, either upon reentering treated areas or from consuminginadvertantly-contaminated food; assess the presence of widely distributedand persistent pesticides in the environment which may result in loss of usable land, surface water, groundwater, and wildlife resources; and, assess the potential environmental exposure of other nontarget organisms, such as fish and wildlife, to pesticides.Another specific purpose of the environmental fate data requirements is tohelp applicants and the Agency estimate expected environmental concentrations of pesticides in specifichabitats where threatened or endangered species or other wildlife populations at risk are found.

(2) Degradation studies . The data from hydrolysis and photolysis studies are used to determine the rate of pesticide degradation and to identify pesticides that may adversely affect nontarget organisms.

(3) Metabolism studies . Data generated from aerobic and anaerobic metabolismstudies are used to determine the nature and availability of pesticides torotational crops and to aid in the evaluation of the persistence of a pesticide.

(4) Mobility studies . These data requirements pertain to leaching, adsorption/desorption, and volatility of pesticides. They provide information on the mode of transport and eventualdestination of the pesticide in the environment. This information is used to assess potential environmental hazards related to: Contamination of human and animal food; loss of usable land and water resources to man through contamination of water (includingground water); and habitat loss of wildlife resulting from pesticide residuemovement or transport in the environment.

(5) Dissipation studies . The data generated from dissipation studies are used to assess potential environmentalhazards (under actual field use conditions) related to: Reentry into treatedareas; hazards from residues in rotational crops and other food sources; and the loss of land as well as surface and ground water resources.

(i) Residue chemistry . (1) Residue chemistry data are used by the Agency to estimate the exposure of the general population to pesticide residues in foodand for setting and enforcing tolerances for pesticide residues in food or feed.

(2) Information on the chemical identity and composition of the pesticide product, the amounts, frequency and time of the pesticide application, andresults of tests on the amount of residues remaining on or in the treated food or feed, are needed to support afinding as to the magnitude and identity of residues which result in food oranimal feed as a consequence of a proposed pesticide usage.

(3) Residue chemistry data are also needed to support the adequacy of one or more methods for the enforcementof the tolerance, and to support practicable methods for removing residues that exceed any proposed tolerance.

(4) Accumulation studies . Accumulation studies indicate pesticide residue levels in food supplies that originate from wild sources or from rotationalcrops. Rotational crop studies are necessary to establish realistic crop rotation restrictions and to determine if tolerances may be needed for residueson rotational crops. Data from irrigated crop studies are used to determine the amount of pesticide residuesthat could be taken up by representative crops irrigated with water containing pesticide residues. These studies allow the Agency to establish label restrictions regarding application of pesticides on sites where the residues can be taken up by irrigated crops.


## 101 Environmental Protection Agency § 158.220

These data also provide information that aids the Agency in establishing any corresponding tolerances that would be needed for residues on suchcrops. Data from pesticide accumulation studies in fish are used to establish label restrictions to prevent applications in certain sites so that therewill be minimal residues entering edible fish or shellfish. These residue dataare also used to determine if a tolerance or action level is needed for residues in aquatic animals eaten by humans.

### (d) Test notes . The following test notes apply to the data requirements in the table to paragraph (c) of this section.

1. Study is required for indoor uses in cases where environmental exposure is likely to occur. Such sites include, but are not limited to, agricultural premises, in or around farm buildings, barnyards, and beehives.

2. Required for aquatic uses for aquatic sites that are intermittently dry. Such sites include, but are not limited to cranberry bogs and rice paddies.

3. Adsorption and desorption using a batch equilibrium method is preferred. However, in some cases, for example, where the pesticide degrades rapidly, soil column leaching withunaged or aged columns may be more appropriate to fully characterize the potential mobility of the parent compound and major transformation products.

### (e) Test notes. The following test notes apply to the requirements in the table to paragraph (d) of this section:

1. Not required if test material is a gas or a highly volatile liquid.

2. Diluted EP testing is required to support the end product registration if results using the EP meet the criteria for restricted use classification under §152.170(b) or special review consideration under §154.7(a)(1).

3. Not required if the test material is corrosive to skin or has a pH of less than 2 or greater than 11.5.

4. Required if the product consists of, orunder conditions of use will result in, a respirable material (e.g., gas, vapor, aerosol, or particulate).


## 120 40 CFR Ch. I (7–1–11 Edition) § 158.500

5. Required if repeated dermal exposure is likely to occur under conditions of use.

6. Required if the test material is an organophosphorus substance, which includes uncharged organophosphorus esters; thioesters or anhydrides of organophosphoric, organophosphonic, or organophosphoramidic acids; or of related phosphorothioic, phosponothioic, or phosphorothioamidic acids; or is structurally related to other substances that may cause the delayed neurotoxicity sometimes seen in this class of chemicals.

7. As determined by the Agency, additional measurements may also be required, such ascholinesterase activity for certain pesticides, e.g., organophosphates and somecarbamates. The route of exposure must correspond with the primary route of exposure.

8. Required for nonfood use pesticides if oral exposure could occur.

9. The 90–day study is required in the ratfor hazard characterization (possibly endpoint selection) and dose-setting for thechronic/carcinogenicity study. It is not required in the mouse, but the Agency would strongly encourage the registrant to conduct a 90–day range finding for the purposes of dose selection for the mouse carcinogenicitystudy to achieve adequate dosing and an acceptable study. The registrant is also encouraged to consult with the Agency on the results of the 90–day mouse study prior to conducting the carcinogenicity study.

10. Required for agricultural uses or if repeated human dermal exposure may occur. Not required if an acceptable 90–day dermal toxicity study is performed and submitted.

11. EP testing is required if the product, or any component of it, may increase dermalabsorption of the active ingredient(s) as determined by testing using the TGAI, or increase toxic or pharmacologic effects.

12. Required for food uses if either of the following criteria is met:

(i) The use pattern is such that the dermalroute would be the primary route of exposure; or

(ii) The active ingredient is known or expected to be metabolized differently by the dermal route of exposure than by the oral route, and a metabolite is the toxic moiety.

13. Required if there is the likelihood of significant repeated inhalation exposure to the pesticide as a gas, vapor, or aerosol.

14. Based on estimates of the magnitude and duration of human exposure, studies of shorter duration, e.g., 21– or 28–days, may besufficient to satisfy this requirement. Registrants should consult with the Agency todetermine whether studies of shorter duration would meet this requirement.

15. Required if results of acuteneurotoxicity study indicate significant statistical or biological effects, or if other available data indicate the potential for this type of delayed neurotoxicity, as determined by the Agency.

16. All 90–day subchronic studies in rats can be designed to simultaneously fulfill the requirements of the 90–day neurotoxicity study using separate groups of animals for testing. Although the subchronic guidelines include the measurement of neurological endpoints, they do not meet the requirement of the 90–day neurotoxicity study.

17. Required if either of the following are met:

(i) The use of the pesticide is likely to result in repeated human exposure over a considerable portion of the human lifespan, as determined by the Agency;

(ii) The use requires a tolerance or an exemption from the requirement of a tolerance.

18. Based on the results of the acute and subchronic neurotoxicity studies, or other available data, a combined chronic toxicity and neurotoxicity study may be required.

19. Studies which are designed to simultaneously fulfill the requirements of both the chronic oral and carcinogenicity studies ( i.e.

,a combined study) may be conducted. Minimum acceptable study durations are:

(i) Chronic rodent feeding study (food use) - 24 months.

(ii) Chronic rodent feeding study (nonfood use) - 12 months.

(iii) Mouse carcinogenicity study - 18 months.

(iv) Rat carcinogenicity study - 24 months.20. Required if any of the following, as determined by the Agency, are met:

(i) The use of the pesticide is likely to result in significant human exposure over a considerable portion of the human life spanwhich is significant in terms of either frequency, duration, or magnitude of exposure;

(ii) The use requires a tolerance or an exemption from the requirement of a tolerance; or

(iii) The active ingredient, metabolite,degradate, or impurity (a) is structurally related to a recognized carcinogen, (b) causes mutagenic effects as demonstrated by in vitro or in vivo testing, or (c) produces a morphologic effect in any organ (e.g.,hyperplasia, metaplasia) in subchronic studies that may lead to a neoplastic change.

21. If this study is modified or waived, a subchronic 90–day oral study conducted in the same species may be required.

22. Testing in two species is required for all

uses.

23. The oral route, by oral intubation, is preferred unless the chemical or physicalproperties of the test substance or the pattern of exposure suggests a more appropriate route of exposure.

24. Additional testing by other routes may be required if the pesticide is determined to be a prenatal developmental toxicant after oral dosing.


## 121 Environmental Protection Agency § 158.510

25. May be combined with the 2–generation reproduction study in rodents by utilizing asecond mating of the parental animals in either generation.

26. Required to support products intendedfor food uses and to support products intended for nonfood uses if use of the productis likely to result in significant human exposure over a portion of the human life span in terms of frequency, magnitude or duration of
exposure.

27. An information-based approach to testing is preferred, which utilizes the best available knowledge on the chemical (hazard,pharmacokinetic, or mechanistic data) to determine whether a standard guideline study,an enhanced guideline study, or an alternative study should be conducted to assess potential hazard to the developing animal, or in some cases to support a waiver for suchtesting. Registrants should submit any alternative proposed testing protocols and supporting scientific rationale to the Agency prior to study initiation.

28. Study required using a weight-of-evidence approach considering:

(i) The pesticide causes treatment-related neurological effects in adult animal studies ( i.e. , clinical signs of neurotoxicity,neuropathology, functional or behavioral effects).

(ii) The pesticide causes treatment-related neurological effects in developing animals, following pre- and postnatal exposure ( i.e.

,nervous system malformations or neuropathy, brain weight changes in offspring,functional or behavioral changes in the offspring).

(iii) The pesticide elicits a causative association between exposures and adverse neurological effects in human epidemiological studies.

(iv) The pesticide evokes a mechanism thatis associated with adverse effects on the development of the nervous system (e.g., SARrelationship to known neurotoxicants, altered neuroreceptor or neurotransmitter responses).

29. The use of a combined study that utilizes the 2–generation reproduction study in rodents as a basic protocol for the addition of other endpoints or functional assessments in the immature animal is encouraged.

30. At a minimum, an initial battery ofmutagenicity tests with possible confirmatory testing is required. Other relevant mutagenicity tests that may have been performed, plus a complete reference list must also be submitted.

31. Choice of assay using either:(i) Mouse lymphoma L5178Y cells, thymidine kinase (tk) gene locus, maximizing assay conditions for small colony expression or detection;

(ii) Chinese hamster ovary (CHO) or Chinese hamster lung fibroblast (V79) cells,hypoxanthine-guanine phosphoribosyl transferase (hgprt) gene locus, accompanied by an appropriate in vitro test for clastogenicity; or

(iii) CHO cells strains AS52, xanthine-guanine phosphoribosyl transferase (xprt) gene locus.

32. The micronucleus rodent bone marrow assay is preferred; however, rodent bonemarrow assays using metaphase analysis (aberrations) are acceptable.

33. Required when chronic or carcinogenicity studies are required. May be required if significant adverse effects are seenin available toxicology studies and these effects can be further elucidated by metabolism studies.

34. May be required if the product’s use will result in exposure to domestic animalsthrough, but not limited to, direct application.

35. A risk assessment assuming that dermal absorption is equal to oral absorption must be performed to determine if the studyis required, and to identify the doses and duration of exposure for which dermal absorption is to be quantified.

36. A 1–year non-rodent study ( i.e. , 1–year dog study) would be required if the Agencyfinds that a pesticide chemical is highly bioaccumulating and is eliminated so slowlythat it does not achieve steady state or sufficient tissue concentrations to elicit an effect during a 90–day study. EPA would requirethe appropriate tier II metabolism and pharmacokinetic studies to evaluate more precisely bioavailability, half-life, and steady state to determine if a longer duration dog toxicity study is needed.


### § 158.510 Tiered testing options for nonfood pesticides.For nonfood use pesticides only, applicants have two options for generating and submitting required toxicology (§158.500) and human exposure(§158.1020, §158.1070, and §158.1410) studies. Applicants are to select one of the following:

## Subpart K—Human Exposure

§ 158.1000 Applicator exposure—general requirements. (a) If EPA determines that industrial standards, such as the workplace standards set by the Occupational Safety and Health Administration (OSHA), provide adequate protection from risk under FIFRA for a particular pesticide use pattern, exposure datamay not be required for that use pattern. Applicants should consult with the Agency on appropriate testing prior to the initiation of studies.

(b) The Agency may accept surrogate exposure data estimations from other sources to satisfy applicator exposure data requirements if the data meet thebasic quality assurance, quality control, good laboratory practice, and other scientific requirements set by EPA. In order to be acceptable, the Agency must find that the surrogateexposure data estimations have adequate information to address applicator exposure data requirements andcontain adequate replicates of acceptable quality data to reflect the specificuse prescribed on the label and the applicator activity of concern, including formulation type, application methods and rates, type of activity, and other pertinent information. The Agency will consider using such surrogate data forevaluating human exposure on a caseby-case basis.

### (e) Test notes . The following test notes apply to the requirements in the table to paragraph (d) of this section:

1. Study is required for indoor uses in cases where environmental exposure is likely to occur. Such sites include, but are not limited to, agricultural premises, in or around farm buildings, barnyards, and beehives.

2. Not required when the electronic absorption spectra, measured at pHs 5, 7, and 9, of the chemical and its hydrolytic products, if any, show no absorption or tailing between 290 and 800 nm.

3. Not required when the chemical is to beapplied only by soil injection or is incorporated in the soil.

4. Requirement based on use patterns and other pertinent factors including, but not limited to, the Henry’s Law Constant of thechemical. In view of methodological difficulties with the study of photodegradation inair, prior consultation with the Agency regarding the protocol is recommended before the test is performed.

5. Required for aquatic food and nonfoodcrop uses for aquatic sites that are intermittently dry. Such sites include, but are not limited to, cranberry bogs and rice paddies.

6. Adsorption and desorption using a batch equilibrium method is preferred. However in some cases, for example, where the pesticide degrades rapidly, soil column leaching withunaged or aged columns may be more appropriate to fully characterize the potential mobility of the parent compound and major transformation products.

7. Environmental chemistry methods used to generate data associated with this studymust include results of a successful confirmatory method trial by an independent laboratory. Test standards and procedures for independent laboratory validation are availableas addenda to the guideline for this test requirement.

8. Requirement for terrestrial uses is basedon potential for aquatic exposure and if pesticide residues have the potential for persistence, mobility, nontarget aquatic toxicity or bioaccumulation. Not required for aquaticresidential uses. Field testing under the terrestrial field dissipation requirement may be more appropriate for some aquatic food crops, such as rice and cranberry uses, that are managed to have a dry-land period for production. The registrant is encouraged to consult with the Agency on protocols.

9. Agency approval of a protocol is necessary prior to initiation of the study.

10. This study may be triggered if there is specific evidence that the presence of onepesticide can affect the dissipation characteristics of another pesticide when applied simultaneously or serially.

11. Required if the weight-of-evidence indicates that the pesticide and/or its degradates is likely to leach to ground water, takinginto account other factors such as the toxicity of the chemicals(s), available monitoring data, and the vulnerability of ground water resources in the pesticide use area.

12. If the terrestrial dissipation study cannot assess all of the major routes of dissipation, the forestry study will be required.

### (e) Test notes . The following test notes apply to the data requirements in the table to paragraph (d) of this section.

1. Required if indoor use could result in pesticide residues in or on food or feed.

2. Material safety data sheets must accompany standards as specified by OSHA in 29 CFR 1910.1200.

3. Required for residential outdoor uses on food crops if the corresponding agricultural use is not approved or the residential use is expected to produce higher residues based on the label directions.

4. Required for indoor uses where the pesticide is applied directly to food, in order to determine metabolites and/or degradates. Not required when only indirect contactwith food would occur (e.g., crack and crevice treatments).

5. Data for fish are required for all pesticides applied directly to water inhabited, or which will be inhabited, by fish that maybe caught or harvested for human consumption.


## 136 40 CFR Ch. I (7–1–11 Edition) §§ 158.1500–158.1900

6. Required when a pesticide is to be applied directly to livestock, to livestock premises, to livestock drinking water, or to crops used for livestock feed. If results from the plant metabolism study show differing metabolites in plants from those found in animals, an additional livestock metabolismstudy involving dosing with the plant metabolite(s) may also be required.

7. Required when the Agency determines that it is reasonably foreseeable that a food or feed crop could be subsequently plantedon the site of pesticide application after harvest or failure of the treated crop. Typically not required for pesticide uses in permanent food crops (e.g., various tree crops, vines) orsemi-permanent crops (e.g., asparagus, pineapples).

8. A residue analytical method suitable for enforcement purposes is required whenever a numeric tolerance (including temporary and time-limited tolerances) is proposed.

9. New analytical methods to be used for enforcement purposes must include results from an independent laboratory validation.

10. A residue method, storage stability data, and crop field trials are required forthe nonfood crop tobacco (green, freshly harvested). Depending on the level of residues found on the green tobacco, additional data may be required on cured/dried tobacco and pyrolysis products.

11. Data are required to determine whether FDA/USDA multiresidue methodology would detect and identify the pesticides and any metabolites.

12. Data are required for any magnitude of the residue study unless analytical samples are stored frozen for 30 days or less, and the active ingredient is not known to be volatile or labile.

13. Studies using single serving samples ofa raw agricultural commodity may be needed for acutely toxic pesticides and/or their metabolites. These residue studies must be conducted using a statistical design accepted by the Agency.

14. Required for indoor uses which are direct postharvest treatments of raw agricultural commodities (e.g., fungicidal waxes or stored grain fumigants).

15. Data on the nature and level of residues in processed food/feed are required if residues could potentially concentrate on processingthus requiring the establishment of a separate tolerance higher than that of the raw agricultural commodity.

16. Required when the pesticide use is a direct application to livestock.

17. Data are required if pesticide residues are present in or on livestock feed items or intentionally added to drinking water. These studies, however, may not be required incases where the livestock metabolism studies indicate negligible transfer of the pesticide’s residues of concern to tissues, milk, and eggs at the maximum expected exposure level for the animals.

18. If results from the plant metabolism study show differing metabolites in plants from those found in animals, an additional livestock feeding study involving dosingwith the plant metabolite(s) may also be required.

19. Data are required whenever a pesticide may be applied directly to water, unless it can be demonstrated that the treated waterwould not be available for human or livestock consumption.

20. Data are required when a pesticide is to be applied directly to water that could be used for irrigation or to irrigation facilities such as irrigation ditches.

21. Data are required whenever a pesticidemay be used in a food handling or feed handling establishment.

22. Required when residues at the tolerance level may result in a risk of concern. Thesedata may include washing, cooking, processing or degradation studies as well as market basket surveys for a more precise residue determination.

23. Typically required if pesticide residues of concern greater than 0.01 ppm are found in crops at the appropriate plant back intervals (taking into account plant back restrictions on product labels) in the confined rotationalcrop study. If residues of concern in the confined study are greater than 0.01 ppm but lessthan the limit of quantitation of the analytical method to be used on field trial samples, the Agency will consider not requiring, on a case-by-case basis, the limited field trials. If there are particular toxicological concerns with the parent pesticide or any metabolites, limited field studies may be needed if such residues are identified at levels below 0.01 ppm in the confined study.

24. Crop field trials are required to establish tolerances on rotational crops when quantifiable residues of concern are observed in the field rotational crops study.

25. Not required for an exemption from atolerance provided that dietary exposure estimates are not needed due to low toxicity or that theoretical estimates of exposure are adequate to assess dietary risk.

26. Not required for an exemption from a tolerance.

S OURCE : 72 FR 61002, Oct. 26, 2007, unless otherwise noted.


## 137 Environmental Protection Agency § 158.2010

§ 158.2000 Biochemical pesticides definition and applicability.This subpart applies to all biochemical pesticides as defined in paragraphs (a), (b), and (c) of this section.

(a) Definitions . The following terms are defined for the purposes of subpart U of this part.

(1) A biochemical pesticide is a pesticide that:

(i) Is a naturally-occurring substanceor structurally-similar and functionally identical to a naturally-occurring substance;

(ii) Has a history of exposure to humans and the environment demonstrating minimal toxicity, or in thecase of a synthetically-derived biochemical pesticides, is equivalent to a naturally-occurring substance that has such a history; and

(iii) Has a non-toxic mode of action to the target pest(s).

(2) A Pheromone is a compound produced by a living organism or is a synthetically derived substance that is structurally similar and functionally identical to a naturally-occurringpheromone, which, alone or in combination with other such compounds,modifies the behavior of other individuals of the same species.

(i) An Arthropod Pheromone is a pheromone produced by a member of the taxonomic phylum Arthropoda.

(ii) A Lepidopteran Pheromone is an arthropod pheromone produced by amember of the insect order Lepidoptera.

(iii) A Straight Chain Lepidopteran Pheromone is a lepidopteran pheromone consisting of an unbranched aliphatic chain (between 9 and 18 carbons) ending in an alcohol, aldehyde, or acetate functional group and containing up to three double bonds in the aliphatic backbone.

(b) Examples . Biochemical pesticides include, but are not limited to:

(1) Semiochemicals (insect pheromones and kairomones),

(2) Natural plant and insect regulators,

(3) Naturally-occurring repellents and attractants, and

(4) Enzymes. (c) Applicability . The Agency may review, on a case-by-case basis, naturally-occurring pesticides that do not clearly meet the definition of a biochemical pesticide in an effort to ensure, to the greatest extent possible,that only the minimum testing sufficient to make scientifically sound regulatory decisions would be conducted. The Agency will review applications for registration of naturally-occurringpesticides to determine whether to review the pesticide under this subpart U.

§ 158.2010 Biochemical pesticides data requirements.
(a) Sections 158.2030 through 158.2070 identify the data requirements that arerequired to support registration of biochemical pesticides. Sections 158.2080through 158.2084 identify the data requirements that are required to support Experimental Use Permits (EUPs). Variations in the test conditions areidentified within the test notes. Definitions that apply to all biochemical data requirements can be found in §158.2000.

(b) Each data table includes ‘‘use patterns’’ under which the individual data are required, with variations including food and nonfood uses for terrestrial and aquatic applications, greenhouse,indoor, forestry, and residential outdoor applications under certain circumstances.

(c) The categories for each data requirement are ‘‘R’’, which stands for required, and ‘‘CR’’ which stands for conditionally required. Generally, ‘‘R’’ indicates that the data are more likelyrequired than for those data requirements with ‘‘CR.’’ However, in each case, the regulatory text preceding the data table and the test notes followingthe data table must be used to determine whether the data requirement must be satisfied.

(d) Each table identifies the test substance that is required to be tested tosatisfy the data requirement. Test substances may include: technical gradeactive ingredient (TGAI), manufacturing-use product (MP), end-use product (EP), typical end-use product(TEP), residue of concern, and pure active ingredient (PAI) or all of the above(All). Commas between the test substances ( i.e. , TGAI, EP) indicate that data may be required on the TGAI or


## 138 40 CFR Ch. I (7–1–11 Edition) § 158.2030

EP or both depending on the conditions set forth in the test note.

(e) The data requirements are organized into a tier-testing system with specified additional studies at highertiers being required if warranted by adverse effects observed in lower tier studies. The lower tier studies are asubset of those required for conventional pesticides, and the studies overall are generally selected from those required for conventional pesticides.

(f) Two sets of guideline numbers are provided for some of the environmentalfate data requirements. For ease of understanding, the current guidelines will be used as an interim measure until the new guidelines (in parentheses) are finalized.

§ 158.2030 Biochemical pesticidesproduct chemistry data requirements table. (a) General . (1) Sections 158.100 through 158.130 describe how to use thistable to determine the product chemistry data requirements for a particular pesticide product. Notes that apply to an individual test and include specific conditions, qualifications, or exceptions to the designated test are listed in paragraph (e) of the section.

(2) Definitions in §158.300 apply to data requirements in this section.

(b) Use patterns . Product chemistrydata are required for all pesticide products and are not use specific.

4. Required if repeated contact with human skin is likely to occur under conditions of

use.

5. Hypersensitivity incidents must be reported as adverse effects data.

6. Required for non-food uses that are likely to result in repeated oral exposure to humans.

7. Required to support uses involving purposeful application to the human skin or which would result in comparable prolonged human exposure to the product (e.g., insectrepellents) and if any of the following criteria are met:

i. Data from a 90–day oral study are not required.

ii. The active ingredient is known or expected to be metabolized differently by the dermal route of exposure than by the oral route and the metabolite is of toxicological

concern.

8. Required if there is a likelihood of significant levels of repeated inhalation exposure to the pesticide as a gas, vapor, or aerosol.

9. Required if the use of the product underwidespread and commonly recognized practice may reasonably be expected to result in significant exposure to female humans (e.g.,occupational exposure or repeated application of insect repellents directly to the skin). Tier II data is required on a different test species from Tier I data when developmentaleffects are observed in the first study and information on species-to-species extrapolation is needed.

10. Required to support nonfood uses if either:

i. The use is likely to result in significant human exposure; or

ii. The active ingredient (or its metabolites) is structurally related to a known mutagen or belongs to any chemical class of compounds containing a known mutagen. Additional mutagenicity tests that mayhave been performed plus a complete reference list must also be submitted. Subsequent testing may be required based on the available evidence.

14. Required if adverse effects are observed in the Tier II immunotoxicity study. The protocol for evaluating adverse effects to the immune response should be developed after evaluating the effects noted in the immunotoxicity study.

15. These data are required when the dataused for the human health assessment indicates that the biochemical may pose a potential hazard to the applicator/user.

16. Required if there is evidence of:i. Endocrinological effects from the subchronic toxicity studies.

ii. Developmental effects in the prenatal developmental toxicity study(s), or

iii. Genotoxicity to mammals based on results from the mutagenicity tests. The use of a combined study that utilizes thetwo-generation reproduction study in rodents (guideline 870.3800) as a basic protocolfor the addition of other endpoints or functional assessments in the immature animal is encouraged.

17. Required if the potential for adverse chronic effects is indicated based on any of the following:

i. The subchronic effect level established inthe following Tier I studies: 90–day oral toxicity study, 90–day dermal toxicity study, or 90–day inhalation toxicity study.

### (e) Test notes . The following testnotes are applicable to the data requirements for biochemical pesticidesnontarget organisms and environmental fate as referenced in the lastcolumn of the table contained in paragraph (d) of this section.

1. Required for the EP when any end-use formulation may contain other ingredients that may be toxic to nontarget organisms or to support arthropod pheromones that wouldbe available to avian wildlife, (e.g., a granular product).

2. Tests for pesticides intended solely for indoor application would be required on a case-by-case basis, depending on use pattern,physical/chemical properties, production volume, and other pertinent factors.

3. Not required for any use groups if thepesticide is highly volatile (estimated volatility > 5 X 10 -5 atm m 3 /mol).

4. Preferred test species are Upland game, waterfowl, or passerine for avian acute oral toxicity studies; Upland game and waterfowl for avian dietary studies; and coldwater fish species for acute freshwater fish studies. 5. Required for the EP when the end-use formulation may contain other ingredients that may be toxic to nontarget organisms.

6. Required on a case-by-case basis when results from Tier I studies indicate adverse effects.

7. Required when results of any one or more of the nontarget organism studies in Tier I indicate potential adverse effects on nontarget organisms and the pesticide is to be applied on land. In view of methdological difficulties with the study of photodegradation in air, prior consultation with the Agency regarding the protocol is recommended before the test is performed.

8. Required when results of any one or more of the nontarget organism studies in Tier I indicate potential adverse effects on nontarget organisms and the pesticide is to be applied in a passive dispenser.

9. Required to support registration of known phytotoxicants, i.e. , herbicides,desiccants, defoliants, and plant growth regulators.

10. Required if environmental fate characteristics indicate that the estimated environmental concentration of the pesticide in the aquatic environment is > 0.01 of any EC 50


## 148 40 CFR Ch. I (7–1–11 Edition) § 158.2070

or LC 50 determined in the aquatic nontarget organism testing.

11. Required if either of the following criteria are met:

i. Environmental fate characteristics indicate that the estimated concentration of the pesticide in the terrestrial environment is > 0.20 the avian dietary LC 50 or equal to > 0.20 the avian oral single dose LD 50 (converted to ppm).

ii. The pesticide or any of its metabolitesor degradation products are stable in the environment to the extent that potentially toxic amounts may persist in the avian or mammalian feed.

12. Required when results of Tier I nontarget organism studies indicate potential adverse effects on nontarget insects and resultsof Tier II tests indicate exposure of nontarget insects. Additional insect species may have to be tested if necessary to address issues raised by use patterns and potentialexposure of important nontarget insect species, (e.g., threatened or endangered species).

13. Required if the product is expected to be transported from the site of applicationby air, soil, or water. The extent of movement would be determined by the results of the Tier II environmental fate studies.

14. Required depending on pesticide mode of action, method and timing of application, and results of any available efficacy data.Typically the honeybee acute toxicity guideline (guideline 850.3020) satisfies this requirement, however, additional nontarget insect species may have to be tested if necessary toaddress issues raised by use patterns and potential exposure of important nontarget insect species, (e.g., endangered species.)


### § 158.2070 Biochemical pesticidesproduct performance data requirements. Product performance data must bedeveloped for all biochemical pesticides. However, the Agency typically does not require applicants to submit such efficacy data unless the pesticide product bears a claim to control publichealth pests, such as pest microorganisms infectious to man in any area of the inanimate environment or a claim to control vertebrates (including but not limited to: rodents, birds, bats, canids, and skunks) or invertebrates(including but not limited to: mosquitoes and ticks) that may directly or indirectly transmit diseases to humans. However, each registrant must ensure through testing that his products are efficacious when used in accordancewith label directions and commonly accepted pest control practices. The Agency reserves the right to require, on a case-by-case basis, submission of efficacy data for any pesticide product registered or proposed for registration.

§ 158.2080 Experimental use permit data requirements—biochemical pesticides.
(a) Sections 158.2081 through 158.2084 describe the experimental use permit(EUP) data requirements for biochemical pesticides. Variations in the test conditions are identified within the test notes. Definitions that apply to all biochemical data requirements can be found in §158.2000.

(b) For general information on the data requirement tables, see §158.2010(b)-(f).

### § 158.2082 Experimental use permit biochemical pesticides residue data requirements table. (a) General . Sections 158.100 through 158.130 describe how to use this table to determine the biochemical pesticidesresidue data requirements for a particular pesticide product and the substance that needs to be tested. Thesedata requirements apply to all biochemical pesticides, i.e. , naturally occurring insect repellents andattractants, semiochemicals (e.g., insect pheromones), natural and plant growth regulators. Notes that apply to an individual test and include specificconditions, qualifications, or exceptions to the designated test are listed in paragraph (e) of this section.

(b) Use patterns . (1) Data are requiredor conditionally required for all pesticides used in or on food and for residential outdoor uses where food crops are grown. Food use patterns include products classified under the general use patterns of terrestrial food crop use, terrestrial feed crop use, aquatic food crop use, greenhouse food crop use, and indoor food use. Data are also conditionally required for aquaticnonfood use if there is direct application to water that could subsequently result in exposure to food.

(2) Data are conditionally required for nonfood uses if pesticide residues may occur in food or feed as a result of the use. Data requirements for these nonfood uses would be determined on a case-by-case basis. For example, mostproducts used in or near kitchens require residue data for risk assessment purposes even though tolerances may not be necessary in all cases.

### (e) Test notes . The following testnotes are applicable to the data requirements for biochemical pesticides product chemistry and are referenced referenced in the last column of the table contained in paragraph (d) of this section.

1. Residue chemistry data requirements apply to biochemical pesticide products when Tier II or Tier III toxicology data are required, as specified for biochemical agents in the biochemical human health assessment data requirements, §158.2050.

2. The same chemical identity data are required for biochemical product chemistrydata requirements,§158.2030 with an emphasis on impurities.

3. Required information includes crops to be treated, rate of application, number and timing of applications, preharvest intervals, and relevant restrictions.

4. Required for residential outdoor uses on food crops if the corresponding agricultural use is not approved or the residential use is expected to produce higher residues based on the label directions.

5. Required unless it is an arthropod pheromone applied at a rate less than or equal to 150 grams active ingredient per acre.

6. Required for indoor uses where the pesticide is applied directly to food, in order to determine metabolites and/or degradates. Not required when only indirect contactwith food would occur (e.g., crack and crevice treatments).

7. Required when a pesticide is to be applied directly to livestock, to livestock premises, to livestock drinking water, or to crops used for livestock feed. If results from


## 152 40 CFR Ch. I (7–1–11 Edition) § 158.2083

the plant metabolism study show differing metabolites in plants form those found in animals, an additional livestock metabolismstudy involving dosing with the plant metabolite(s) may also be required.

8. Livestock feeding studies are required whenever a pesticide residue is present in livestock feed or when direct application to livestock uses occurs.

9. Required if indoor use could result in pesticide residues in or on food or feed.

10. Data are required to determine whether FDA/USDA multiresidue methodology would detect and identify the pesticides and any metabolites.

11. Data are required whenever a pesticide may be applied directly to water, unless it can be demonstrated that the treated waterwould not be available for human or livestock consumption.

12. Data on fish are required for all pesticides applied directly to water inhabited, or which will be inhabited, by fish that maybe caught or harvested for human consumption.

13. Data are required when a pesticide is to be applied directly to water that could be used for irrigation or to irrigation facilities such as irrigation ditches.

14. Data are required whenever a pesticidemay be used in food/feed handling establishments.

15. Data on the nature and level of residue in processed food/feed are required whendetectible residues could potentially concentrate on processing thus requiring the establishment of a separate tolerance higherthan that of the raw agricultural commodity.

16 Anticipated residue data are requiredwhen the assumption of tolerance level residues would result in predicted exposure at an unsafe level of exposure. Data, using singleserving samples of a raw agricultural commodity, on the level or residue in food as consumed would be used to obtain a moreprecise estimate of potential dietary exposure. These data may also include washing, cooking, processing or degradation studies as well as market basket surveys for a more precise residue determination.

17. The proposed tolerance must reflect the maximum residue likely to occur in crops, in meat, milk, poultry, or eggs.

18. Required when a residue analytical method is required.

## Subpart V—Microbial Pesticides

S OURCE : 72 FR 61002, Oct. 26, 2007, unless otherwise noted.



### § 158.2100 Microbial pesticides definition and applicability.
(a) This subpart applies to all livingor dead microbial pesticides as described in paragraphs (b) and (c) of this section.

(b) Definition

. Microbial pesticide is amicrobial agent intended for preventing, destroying, repelling, or mitigating any pest, or intended for use asa plant regulator, defoliant, or desiccant, that:

(1) Is a eucaryotic microorganism including, but not limited to, protozoa, algae, and fungi; (2) Is a procaryotic microorganism, including, but not limited to, Eubacteria and Archaebacteria; or

(3) Is a parasitically replicating microscopic element, including, but not limited to, viruses.

(c) Applicability . (1) This part applies to microbial pesticides as specified inparagraphs (c)(2), (3) and (4) of this section.

(2) Each new isolate of a microbial pesticide is treated as a new strain and must be registered independently ofany similar registered microbial pesticide strain and supported by data required in this subpart.

(3) Genetically modified microbial pesticides may be subject to additional data or information requirements on a case-by-case basis depending on the particular microbial agent and/or its parental strains, the proposed pesticide use pattern, and the manner and extentto which the organism has been genetically modified.

(4) Pest control organisms such as insect predators, nematodes, and macroscopic parasites are exempt from the requirements of FIFRA as authorized by section 25(b) of FIFRA and specified in §152.20 (a) of this chapter.

§ 158.2110 Microbial pesticides data requirements. (a) For all microbial pesticides. (1) The following §158.2120 through §158.2150 identify the data requirements that arerequired to support registration of microbial pesticides. The variations inthe test conditions are identified within the test notes.

(2) Each data table includes ‘‘use patterns’’ under which the individual data are required, with variations including all use patterns, food and nonfood uses


## 156 40 CFR Ch. I (7–1–11 Edition) § 158.2120

for terrestrial and aquatic applications, greenhouse, indoor, forestry, and residential outdoor applications under certain circumstances.

(3) The categories for each data requirement are ‘‘R,’’ which stands for required, and ‘‘CR’’ which stands forconditionally required. If a bracket appears around the ‘‘R’’ or ‘‘CR,’’ thedata are required for both the registration and experimental use permit requests. Generally, ‘‘R’’ indicates that the data are more likely required than for those data requirements with‘‘CR.’’ However, in each case, the regulatory text preceding the data table and the test notes following the datatable must be used to determine whether the data requirement must be satisfied.

(4) Each table identifies the test substance that is required to be tested tosatisfy the data requirement. Test substances may include: technical gradeactive ingredient (TGAI), manufacturing-use product (MP), end-use product (EP), typical end-use product(TEP), residue of concern, and pure active ingredient (PAI) or all of the above(All). Commas between the test substances ( i.e. , TGAI, EP) indicate that data may be required on the TGAI or EP or both depending on the conditionsset forth in the test note. Data requirements which list two test substances ( i.e. , TGAI and EP) indicate that bothare required to be tested. Data requirements that list only MP as the test substance apply to products containing solely the technical grade of the active ingredient and manufacturing-use products to which other ingredientshave been intentionally added. Data requirements listing the EP as the testsubstance apply to any EP with an ingredient in the end-use formulation other than the active ingredient that is expected to enhance the toxicity of the product.

(b) Additional data requirements for genetically modified microbial pesticides.Additional requirements for genetically modified microbial pesticidesmay include but are not limited to: genetic engineering techniques used; the identity of the inserted or deleted gene segment (base sequence data or enzymerestriction map of the gene); information on the control region of the gene in question; a description of the ‘‘new’’traits or characteristics that are intended to be expressed; tests to evaluate genetic stability and exchange; andselected Tier II environmental expression and toxicology tests.

### (d) Test notes . The following testnotes are applicable to the data requirements for microbial pesticidestoxicology as referenced in the last column of the table contained in paragraph (c) of this section:

1. The acute oral toxicity/pathogenicitystudy is required to support the TGAI. However, it can be combined with the unit dose portion of the acute oral toxicity study, withan EP or MP test material to fulfill the requirement for the TGAI and the MP or EP ina single study, if the new protocol is designed to address the endpoints of concern.

2. Data not required for products whose active ingredient is a virus. For test materials whose size or consistency may prevent use of an intravenous injection, the intraperitoneal injection procedure may be employed.

3. Hypersensitivity incidents, including immediate type and delayed-type reactions of humans or domestic animals, occur during the testing or production of the TGAI, MP,or EP, or are otherwise known to the applicant must be reported if they occur.

4. Data must be submitted only for products whose active ingredient is a virus.

5. The 870 series studies for the MP and EP are intended to provide data on the acute toxicity of the product. Waivers for any or all of these studies may be granted when theapplicant can demonstrate that the combination of inert ingredients is not likely to pose any significant human health risks. Where appropriate, the limit dose approach to testing is recommended.

6. Required when the product consists of, or under conditions of use would result in, aninhalable material (e.g., gas, volatile substances, or aerosol particulate).

7. Data required when significant toxicity,in the absence of pathogenicity and significant infectivity, is observed in acute oral, injection, or pulmonary studies (Tier I). Route(s) of exposure correspond to route(s)where toxicity was observed in Tier I studies. The toxic component of the TGAI is to be tested.

8. Data required when significant infectivity and/or unusual persistence is observed in the absence of pathogenicity or toxicity in Tier I studies. Routes of exposure (oral and/ or pulmonary) correspond to routes in Tier I studies where adverse effects were noted.Data may also be required to evaluate adverse effects due to microbial contaminants or to toxic byproducts.

9. Data are required when one or more of the following criteria are met:

i. Significant infectivity of the microbial pest control agent (MPCA) was observed in test animals in the Tier II subchronic study and in which no significant signs of toxicity or pathogenicity were observed.

ii. The microbial pesticide is a virus which can persist or replicate in mammalian cell culture lines.

iii. The microbial pesticide is not amenable to thorough taxonomic classification, and is related to organisms known to be parasitic for mammalian cells.

iv. The microbial pesticide preparation isnot well purified, and may contain contaminants which are parasitic for mammals.

10. Data may be required for products known to contain or suspected to containcarcinogenic viruses or for microbial components that are identified as having significant toxicity in Tier II testing.

11. Data may be required for productsknown to contain or suspected to contain viruses that can interact in an adverse manner with components of the mammalian immune system.

12. An analysis of human infectivity/pathogenicity potential using scientific literature, genomic analysis, and/or actual specific cell culture/animal data may be required for products known to contain or suspected ofcontaining intracellular parasites of mammalian cells for products that exhibit pathogenic characteristics in Tier I and/or Tier II, for products which are closely related toknown human pathogens based on the product analysis data, or for known humanpathogens that have been ‘‘disarmed’’ or rendered non-pathogenic for humans.

13. Test standards may have to be modified depending on the characteristics of the microorganism. Requirements may vary for


## 160 40 CFR Ch. I (7–1–11 Edition) § 158.2150

these studies depending on the active ingredient being tested. Consultation with the Agency is advised before performing these Tier III studies.

fate as referenced in the last column of the table contained in paragraph (d) of this section.

1. Tests for pesticides intended solely for indoor application would be required on a case-by-case basis, depending on use pattern,production volume, and other pertinent factors.

2. The preferred species for the avian oralstudy is either the upland game or waterfowl. The preferred species for the avian inhalation toxicity/pathogenicity study and the avian chronic toxicity/pathogenicity study is the upland game. There is also theoption to test the passerine if there is a concern. The coldwater fish is preferred for freshwater fish testing. However, two species (coldwater and warmwater fish species are the preferred species) must be tested for usesinvolving direct freshwater exposure. Freshwater invertebrate testing is also required.

3. Data required when the nature of the microbial pesticide and/or its toxins indicates potential pathogenicity to birds.

4. Required on a case-by-case basis if results of tests required by §158.2140 are inadequate or inappropriate for assessment of hazards to wild mammals.

5. Required when there will be significantexposure to aquatic organisms (fish and invertebrates).

6. Required if the product is intended fordirect application into the estuarine or marine environment or expected to enter this environment in significant concentrations because of expected use or mobility pattern.

7. Required if the microbial pesticide is taxonomically related to a known plant pathogen.

8. Data are not required unless an activemicrobial ingredient controls the target insect pest by a mechanism of infectivity; i.e.

,may create an epizootic condition in nontarget insects.

9. Required if toxic or pathogenic effects are observed in one or more of the following tests for microbial pesticides:

i. Avian acute oral or avian inhalation studies.

ii. Wild mammal studies. iii. Nontarget plant studies (terrestrial). iv. Honey bee studies. v. Nontarget insect studies.10. Required when toxic or pathogenic effects are observed in any of the following Tier I tests for microbial pest control agents:

i. Freshwater fish studies. ii. Freshwater invertebrate studies. iii. Nontarget plant studies (aquatic). 11. Required if product is applied on land orin fresh water or marine/estuarine environments and toxic or pathogenic effects are observed in any of the following Tier I tests for microbial pesticides:

i. Estuarine and marine animal toxicity and pathogenicity. ii. Plant studies - estuarine or marine species.

12. An appropriate dose-response toxicitytest is required when toxic effects on nontarget terrestrial wildlife or aquatic organisms (including plants) are reported in one or more Tier I tests and results of Tier II tests indicate exposure of the microbial agent to the affected nontarget terrestrial wildlife or aquatic organisms. The protocols for these tests may have to be modified in accordance with results from the nontarget organism and environmental expression studies.

13. Required when one or more of the following are present:

i. Pathogenic effects are observed in Tier I avian studies.

ii. Tier II environmental expression testingindicate that long-term exposure of terrestrial animals is likely.

14. Required when product is intended for use in water or expected to be transported to water from the intended use site, and when pathogenicity or infectivity was observed in Tier I aquatic studies.

15. Required if, after an analysis of the microbial pesticide’s ability to survive andmultiply in the environment and what ecological habitat it would occupy, the intendeduse patterns, and the results of previous nontarget organisms and environmental expression tests, it is determined that use of the microbial agent may result in adverse effectson the nontarget organisms in aquatic environments. Testing is to determine if applications of the microbial pest control would beexpected to disrupt the balance of populations in the target ecosystem.

16. Tier IV studies may be conducted as a condition of registration as post-registration monitoring if the potential for unreasonable adverse effects appears to be minimal during that period of use due to implementation of mitigation measures.

17. Required when both of the following conditions occur:

i. Pathogenic effects observed at actual orexpected field residue exposure levels are reported in Tier III; and

ii. The Agency determines that quarantine methods would not prevent the microbial pesticide from contaminating areas adjacent to the test area.

18. Short term simulated or actual field studies are required when it is determined that the product is likely to cause adverseshort-term or acute effects, based on consideration of available laboratory data, use patterns, and exposure rates.

19. Data from a long-term simulated field test (e.g., where reproduction and growth of confined populations are observed) and/or an actual field test (e.g., where reproductionand growth of natural populations are observed) are required if laboratory data indicate that adverse long-term, cumulative, or


## 163 Environmental Protection Agency § 158.2171

life-cycle effects may result from intended

use.

20. Since test standards would be developed on a case-by-case basis, consultation with the Agency and development of a protocol is advised before performing these Tier IV studies.


### § 158.2160 Microbial pesticides product performance data requirements. Product performance data must be developed for all microbial pesticides.However, the Agency has waived all requirements to submit efficacy data unless the pesticide product bears a claim to control public health pests, such as pest microorganisms infectious to manin any area of the inanimate environment or a claim to control vertebrates (including but not limited to: rodents,birds, bats, canids, and skunks) or invertebrates (including but not limitedto: mosquitoes and ticks) that may directly or indirectly transmit diseases to humans. However, each registrant must ensure through testing that his products are efficacious when used in accordance with label directions andcommonly accepted pest control practices. The Agency reserves the right torequire, on a case-by-case basis, submission of efficacy data for any pesticide product registered or proposed for registration.
§ 158.2170 Experimental use permitdata requirements—microbial pesticides. (a) For all microbial pesticides. (1) The following §158.2171 through §158.2174 identify the data requirements that are required to support experimental use permits for microbial pesticides. The variations in the test conditions are identified within the test notes.

(2) For general information on the data requirement tables, see §158.2110(a)(2)-(4). (b) Additional data requirements for genetically modified microbial pesticides.Additional requirements for genetically modified microbial pesticidesmay include but are not limited to: genetic engineering techniques used; the identity of the inserted or deleted gene segment (base sequence data or enzymerestriction map of the gene); information on the control region of the gene in question; a description of the ‘‘new’’traits or characteristics that are intended to be expressed; tests to evaluate genetic stability and exchange; andselected Tier II environmental expression and toxicology tests.

### (d) Test notes . The following testnotes are applicable to the data requirements for experimental use permit microbial pesticides product analysis as referenced in the last column of the table contained in paragraph (c) of this section.

1. If an experimental use permit is being sought, and if the pesticide is not alreadyunder full-scale production, a schematic diagram and/or description of the manufacturing process suffices.

2. If an experimental use permit is being sought, and if the product is not already under full-scale production, a discussion of unintentional ingredients is required to be submitted to the extent this information is available.

3. Required to support registration of eachmanufacturing-use product and end-use product. This analysis must be conducted at the point in the production process after which there would be no potential for microbial contamination or microbial regrowth. Forpesticides in the production stage, a preliminary product analytical method and data would suffice to support an experimental use permit. For full registration, generally an analysis of samples is a compilation of batches, over a period of time, depending on the frequency of manufacturing.

4. Only required for emulsifiable liquid forms of microbial pesticides.

5. Required when microbial pesticides arepackaged in metal, plastic, or paper containers.

6. Only required for liquid forms of microbial pesticides.

(d) Test notes . The following testnotes are applicable to the data requirements for experimental use permit microbial pesticides toxicology as referenced in the last column of the table contained in paragraph (c) of this section:

1. The acute oral toxicity/pathogenicitystudy is required to support the TGAI. However, it can be combined with the unit dose portion of the acute oral toxicity study, withan EP or MP test material to fulfill the requirement for the TGAI and the MP or EP ina single study, if the new protocol is designed to address the endpoints of concern.

2. Data not required for products whose active ingredient is a virus. For test materials whose size or consistency may prevent use of an intravenous injection, the intraperitoneal injection procedure may be employed.

3. Hypersensitivity incidents, including immediate type and delayed type reactions of humans or domestic animals occur during the testing or production of the TGAI, MP,or EP, or are otherwise known to the applicant must be reported if they occur.

4. Data must be submitted only for products whose active ingredient is a virus.

5. The 870 series studies for the MP and EP are intended to provide data on the acute toxicity of the product. Waivers for any or all of these studies may be granted when theapplicant can demonstrate that the combination of inert ingredients is not likely to pose any significant human health risks. Whereappropriate, the limit dose approach to testing is recommended.

6. Required when the product consists of, or under conditions of use that would result in an inhalable material (e.g., gas, volatile substances, or aerosol particulate).

### (e) Test notes . The following testnotes are applicable to the data requirements for microbial pesticides nontarget organism and environmental fate as referenced in the last column of the table contained in paragraph (d) of this section.

1. Tests for pesticides intended solely for indoor application would be required on a case-by-case basis, depending on use pattern,production volume, and other pertinent factors. Tests to support EUP’s are based on the application timing and acreage.

2. The preferred species for the avian oralstudy is either the upland game or waterfowl. The preferred species for the avian inhalation toxicity/pathogenicity study and the avian chronic toxicity/pathogenicity study is the upland game. There is also the option to test a passerine species if there is a concern. The coldwater fish is preferred for freshwater fish testing. However, two species(coldwater and warmwater fish are the preferred species) must be tested for uses involving direct freshwater exposure. Freshwater invertebrates are preferred for invertebrate testing.

3. Required when there will be significantexposure to aquatic organisms (fish and invertebrates).

4. Required if the microbial pesticide is taxonomically related to a known plant pathogen.

5. Data are not required unless an activemicrobial ingredient controls the target insect pest by a mechanism of infectivity; i.e.

,may create an epizootic condition in nontarget insects.
