G. Other Labeling Requirements 1. Endangered Species Statement The Agency has developed the Endangered Species Protection Program to identify pesticides whose use may cause adverse impacts on endangered and threatened species, and to implement mitigation measures that address these impacts. The Endangered Species Act requires federal agencies to ensure that their actions are not likely to jeopardize listed species or adversely modify designated critical habitat. To analyze the potential of registered pesticide uses to affect any particular species, EPA puts basic toxicity and exposure data developed for REDs into context for individual listed species and their locations by evaluating important ecological parameters, pesticide use information, the geographic relationship between specific pesticide uses and species locations, and biological requirements and behavioral aspects of the particular species. This analysis will take into consideration any regulatory changes recommended in this RED that are being implemented at this time. A determination that there is a likelihood of potential impact to a listed species may result in limitations on use of the pesticide, other measures to mitigate any potential impact, or consultations with the Fish and Wildlife Service and/ or the National Marine Fisheries Service as necessary.

The Endangered Species Protection Program as described in a Federal Register notice ( 54 FR 27984 28008, July 3, 1989) is currently being implemented on an interim basis. As part of the interim program, the Agency has developed County Specific Pamphlets that articulate many of the specific measures outlined in the Biological Opinions issued to date. The Pamphlets are available for voluntary use by pesticide applicators on EPA's website at www. epa. gov/ espp. A final Endangered Species Protection Program, which may be altered from the interim program, has been proposed for public comment in the Federal Register ( 67 FR # 231, December 2, 2002; edocket OPP 2002 0311.) 45 2. Spray Drift Management Approximately 90% of oxadiazon is applied as a granular formulation, for which spray drift is not a concern. The approximately 10% of oxadiazon that is applied as a spray using a wettable powder formulation is applied to nursery stock and non turf areas of golf courses using handheld sprayers and to sod farms using tractor drawn boom sprayers. The wettable powder formulation is not typically used around bodies of water, so that the risk of contamination of water with oxadiazon as a result of spray drift is not of concern. No label language is required to address ecological or drinking water concerns that arise from off target drift from spray applications of oxadiazon.

To address the risk to human health associated with off target drift from spray applications, the following label language is required for oxadiazon wettable powder products: " Do not apply this product in a way that will contact workers or other persons either directly or through drift."

The Agency is currently working with stakeholders to develop appropriate generic label statements to address off target drift risk. Once this process has been completed, oxadiazon products may need to be revised to include this additional language.

V. Actions Required of Registrants In order to be eligible for reregistration, registrants need to implement the risk mitigation measures outlined in Section IV, which include, among other things, submission of the following:

The MUP labeling should bear the labeling contained in the table at the end of this section. The MUP label will explicitly prohibit use of products that do not conform to Section V. B. 2 of this document.

B. End Use Products 48 1. Additional Product Specific Data Requirements Section 4( g)( 2)( B) of FIFRA calls for the Agency to obtain any needed product specific data regarding the pesticide after a determination of eligibility has been made. Registrants must review previous data submissions to ensure that they meet current EPA acceptance criteria and if not, commit to conduct new studies. If a registrant believes that previously submitted data meet current testing standards, then the study MRID numbers should be cited according to the instructions in the Requirement Status and Registrants Response Form provided for each product.

2. Labeling for End Use Products Labeling changes are necessary to implement measures outlined in Section V above. Specific language to implement these changes is specified in Table 14 at the end of this section.

Citations Considered to be Part of the Database Supporting the Reregistration Decision ( Bibliography) 67 Appendix D. CITATIONS CONSIDERED TO BE PART OF THE DATA BASE SUPPORTING THE INTERIM REREGISTRATION DECISION ( BIBLIOGRAPHY)

GUIDE TO APPENDIX D 1. CONTENTS OF BIBLIOGRAPHY. This bibliography contains citations of all studies considered relevant by EPA in arriving at the positions and conclusions stated elsewhere in the Reregistration Eligibility Document. Primary sources for studies in this bibliography have been the body of data submitted to EPA and its predecessor agencies in support of past regulatory decisions. Selections from other sources including the published literature, in those instances where they have been considered, are included.

2. UNITS OF ENTRY. The unit of entry in this bibliography is called a " study". In the case of published materials, this corresponds closely to an article. In the case of unpublished materials submitted to the Agency, the Agency has sought to identify documents at a level parallel to the published article from within the typically larger volumes in which they were submitted. The resulting " studies" generally have a distinct title ( or at least a single subject), can stand alone for purposes of review and can be described with a conventional bibliographic citation. The Agency has also attempted to unite basic documents and commentaries upon them, treating them as a single study.

3. IDENTIFICATION OF ENTRIES. The entries in this bibliography are sorted numerically by Master Record Identifier, or " MRID" number. This number is unique to the citation, and should be used whenever a specific reference is required. It is not related to the six digit " Accession Number" which has been used to identify volumes of submitted studies ( see paragraph 4( d)( 4) below for further explanation). In a few cases, entries added to the bibliography late in the review may be preceded by a nine character temporary identifier. These entries are listed after all MRID entries. This temporary identifying number is also to be used whenever specific reference is needed.

4. FORM OF ENTRY. In addition to the Master Record Identifier ( MRID), each entry consists of a citation containing standard elements followed, in the case of material submitted to EPA, by a description of the earliest known submission. Bibliographic conventions used reflect the standard of the American National Standards Institute ( ANSI), expanded to provide for certain special needs.

a Author. Whenever the author could confidently be identified, the Agency has chosen to show a personal author. When no individual was identified, the Agency has shown an identifiable laboratory or testing facility as the author. When no author or laboratory could be identified, the Agency has shown the first submitter as the author.

b. Document date. The date of the study is taken directly from the document. When the date is followed by a question mark, the bibliographer has deduced the date from the evidence contained in the document. When the date appears as ( 1999), the Agency was unable to determine or estimate the date of the document. 68 c. Title.

Generic Data Call in 78 Appendix F. Product specific Data Call in 79 Appendix G. EPA's Batching of Oxadiazon Products for Meeting Acute Toxicity Data Requirements for Reregistration 80 EPA'S BATCHING OF OXADIAZON PRODUCTS FOR MEETING ACUTE TOXICITY DATA REQUIREMENTS FOR REREGISTRATION In an effort to reduce the time, resources and number of animals needed to fulfill the acute toxicity data requirements for reregistration of products containing Oxadiazon the primary active ingredient, the Agency has batched products which can be considered similar for purposes of acute toxicity. Factors considered in the sorting process include each product's active and inert ingredients ( identity, percent composition and biological activity), type of formulation ( e. g., emulsifiable concentrate, aerosol, wettable powder, granular, etc.), and labeling ( e. g., signal word, use classification, precautionary labeling, etc.). Note the Agency is not describing batched products as " substantially similar" since some products with in a batch may not be considered chemically similar or have identical use patterns.

Using available information, batching has been accomplished by the process described in the preceding paragraph. Notwithstanding the batching process, the Agency reserves the right to require, at any time, acute toxicity data for an individual product should need arise.

Registrants of products within a batch may choose to cooperatively generate, submit or cite a single battery of six acute toxicological studies to represent all the products within that batch. It is the registrants' option to participate in the process with all other registrants, only some of the other registrants, or only their own products within in a batch, or to generate all the required acute toxicological studies for each of their own products. If the registrant chooses to generate the data for a batch, he/ she must use one of the products within the batch as the test material. If the registrant chooses to rely upon previously submitted acute toxicity data, he/ she may do so provided that the data base is complete and valid by to days standards ( see acceptance criteria attached), the formulation tested is considered by EPA to be similar for acute toxicity, and the formulation has not been significantly altered since submission and acceptance of the acute toxicity data. Regardless of whether new data is generated or existing data is referenced, the registrants must clearly identify the test material by EPA Registration Number. If more than one confidential statement of formula ( CSF) exists for a product, the registrant must indicate the formulation actually tested by identifying the corresponding CSF.

In deciding how to meet the product specific data requirements, registrants must follow the directions given in the Data Call In Notice and its attachments appended to the RED. The DCI Notice contains two response forms which are to be completed and submitted to the Agency within 90 days of receipt. The first form, " Data Call in Response, " asks whether the registrant will meet the data requirements for each product. The second form, " Requirements Status and Registrant's Response," lists the product specific data required for each product, including the standard six acute toxicity tests. A registrant who wishes to participate in a batch must decide whether he/ she will provide the data or depend on someone else to do so. If the registrant supplies the data to support a batch of products, he/ she must select the one of the following options: Developing data ( Option 1), 81 Submitting an existing Study ( Option 4), Upgrading an existing Study ( Option 5), or Citing an Existing Study ( Option ). If a registrant depends on another's data, he/ she must choose among: Cost sharing ( Option 2), Offers to Cost Share ( Option 3) or Citing an Existing Study ( Option 6). If a registrant does not want to participate in a batch, the choices are Options 1, 4, 5 or 6. However, a registrant should know that choosing not to participate in a batch does not preclude other registrants in the batch from citing his/ her studies and offering to cost share ( Option 3) those studies.

Forty six products were found which contain Oxadiazon as the active ingredient. These products have been placed into five batches and a No batch in accordance with the active and inert ingredients and type of formulation.
