Requests to present oral comments will be accepted until the date of the meeting and, to the extent that time permits, the Chair of FIFRA SAP may permit the presentation of oral comments at the meeting by interested persons who have not previously requested time. The request should identify the name of the individual making the presentation, the organization (if any) the individual will represent, and any requirements for audiovisual equipment (e.g., overhead projector, 35 mm projector, chalkboard). Oral comments before FIFRA SAP are limited to approximately 5 minutes unless prior arrangements have been made. In addition, each speaker should bring 20 copies of his or her comments and presentation slides for distribution to the FIFRA SAP at the meeting.

3. Seating at the meeting. Seating at the meeting will be open and on a first-come basis.

4. Request for nominations to serve as ad hoc members of FIFRA SAP for this meeting. As part of a broader process for developing a pool of candidates for each meeting, FIFRA SAP staff routinely solicits the stakeholder community for nominations of prospective candidates for service as ad hoc members of FIFRA SAP. Any interested person or organization may nominate qualified individuals to be considered as prospective candidates for a specific meeting. Individuals nominated for this meeting should have expertise in one or more of the following areas: Regulatory toxicology/weight-of-evidence risk assessment, ecotoxicology (fish and amphibian toxicology), comparative endocrinology, reproductive physiology, developmental biology/toxicology, thyroid physiology, in vitro models, toxicological pathology, amphibian histopathology, morphometrics, quantitative ecology/biostatistics, systems biology, and Baysian statistics. Nominees should be scientists who have sufficient professional qualifications, including training and experience, to be capable of providing expert comments Start Printed Page 22875on the scientific issues for this meeting. Nominees should be identified by name, occupation, position, address, and telephone number. Nominations should be provided to the DFO listed under FOR FURTHER INFORMATION CONTACT on or before May 2, 2013. The Agency will consider all nominations of prospective candidates for this meeting that are received on or before this date. However, final selection of ad hoc members for this meeting is a discretionary function of the Agency.

The selection of scientists to serve on FIFRA SAP is based on the function of the panel and the expertise needed to address the Agency's charge to the panel. No interested scientists shall be ineligible to serve by reason of their membership on any other advisory committee to a Federal department or agency or their employment by a Federal department or agency, except the EPA. Other factors considered during the selection process include availability of the potential panel member to fully participate in the panel's reviews, absence of any conflicts of interest or appearance of lack of impartiality, independence with respect to the matters under review, and lack of bias. Although financial conflicts of interest, the appearance of lack of impartiality, lack of independence, and bias may result in disqualification, the absence of such concerns does not assure that a candidate will be selected to serve on FIFRA SAP. Numerous qualified candidates are identified for each Panel. Therefore, selection decisions involve carefully weighing a number of factors including the candidates' areas of expertise and professional qualifications and achieving an overall balance of different scientific perspectives on the Panel. In order to have the collective breadth of experience needed to address the Agency's charge for this meeting, the Agency anticipates selecting approximately 15 ad hoc scientists.

FIFRA SAP members are subject to the provisions of 5 CFR part 2634, Executive Branch Financial Disclosure, as supplemented by the EPA in 5 CFR part 6401. In anticipation of this requirement, prospective candidates for service on the FIFRA SAP will be asked to submit confidential financial information which shall fully disclose, among other financial interests, the candidate's employment, stocks and bonds, and where applicable, sources of research support. The EPA will evaluate the candidates financial disclosure form to assess whether there are financial conflicts of interest, appearance of a lack of impartiality or any prior involvement with the development of the documents under consideration (including previous scientific peer review) before the candidate is considered further for service on FIFRA SAP. Those who are selected from the pool of prospective candidates will be asked to attend the public meetings and to participate in the discussion of key issues and assumptions at these meetings. In addition, they will be asked to review and to help finalize the meeting minutes. The list of FIFRA SAP members participating at this meeting will be posted on the FIFRA SAP Web site at​scipoly/​sap or may be obtained from the OPP Docket at

II. Background

A. Purpose of FIFRA SAP

FIFRA SAP serves as the primary scientific peer review mechanism of EPA's Office of Chemical Safety and Pollution Prevention (OCSPP) and is structured to provide scientific advice, information, and recommendations to the EPA Administrator on pesticides and pesticide-related issues as to the impact of regulatory actions on health and the environment. FIFRA SAP is a Federal advisory committee established in 1975 under FIFRA that operates in accordance with requirements of the Federal Advisory Committee Act. FIFRA SAP is composed of a permanent panel consisting of seven members who are appointed by the EPA Administrator from nominees provided by the National Institutes of Health and the National Science Foundation. FIFRA established a Science Review Board consisting of at least 60 scientists who are available to the FIFRA SAP on an ad hoc basis to assist in reviews conducted by the FIFRA SAP. As a peer review mechanism, FIFRA SAP provides comments, evaluations and recommendations to improve the effectiveness and quality of analyses made by Agency scientists. Members of FIFRA SAP are scientists who have sufficient professional qualifications, including training and experience, to provide expert advice and recommendation to the Agency.

B. Public Meeting

EPA developed the Endocrine Disruptor Screening Program (EDSP) in response to FFDCA section 408(p) which requires EPA to “develop a screening program, using appropriate validated test systems and other scientifically relevant information, to determine whether certain substances may have an effect in humans that is similar to an effect produced by a naturally occurring estrogen, or such other endocrine effect as the Administrator may designate.” 21 U.S.C. 346a(p)(1). In addition, the provision in section 1457 of the Safe Drinking Water Act (SDWA) provides that “the Administrator may provide for testing under the screening program * * * any other substance that may be found in sources of drinking water if the Administrator determines that a substantial population may be exposed to such substance.” 42 U.S.C. 300j-17.

Based on recommendations from the Endocrine Disrupter Screening and Testing Advisory Committee (EDSTAC) and, pursuant to the EPA Administrator's discretionary authority, the EPA expanded the program to encompass the estrogen, androgen, and thyroid (E, A, and T) hormonal pathways of the endocrine system and human and ecological effects. Subsequent to review by a joint committee of the EPA's Science Advisory Board (SAB) and the FIFRA SAP, the EDSP embarked on a validation process as mandated to evaluate the relevance and reliability of Tier 1 screening and Tier 2 test methods. As recommended by a FIFRA SAP, the current EDSP Tier 1 screening battery consists of both in vitro and in vivo assays that provide redundancy within a particular mode or pathway of action and complementary endocrine specific-endpoints sensitive enough to detect effects on E, A, and T signaling through different routes of exposure and across multiple life-stages and taxa. The degree of redundancy and complementary assays/endpoints are intended to provide corroborating information to support an evaluation of the Tier 1 screening results.

EPA issued the first test orders of the EDSP Tier 1 screening on 67 chemicals (List 1 chemicals) between October 29, 2009, and February 26, 2010 (​endo). As a result of these test orders, EDSP Tier 1 data were submitted on 50 pesticide active ingredients and 2 pesticide inert ingredients. For some test orders, EPA accepted “other scientifically relevant information” (OSRI) in lieu of specific study data (​endo).

In May 2013, the Agency will be holding a FIFIRA SAP meeting to obtain input to ensure that individual assays and the overall battery performed as anticipated toward understanding whether a chemical is impacting E, A, and T pathways. A subset of the List 1 chemicals will be presented to the Panel to evaluate whether each assay can be consistently executed based on the performance criteria and to discuss any issues associated with interpretation of the responses within each assay as well Start Printed Page 22876as the anticipated complementary relationships both within and across the assays. The advice and recommendations of the Panel from the May FIFRA SAP will be critical in how the Agency conducts its weight-of-evidence (WoE) evaluation of the Tier 1 screening results, which is the topic of this FIFRA SAP.

The EPA issued its WoE guidance document in 2011 for evaluating the results of EDSP Tier 1 screening to identify the need for Tier 2 testing. That document can be found at (Docket ID number EPA-HQ-OPPT-2010-0877). Briefly, that document presents a hypothesis-based approach that begins with an evaluation of each study's quality and relevance in addressing the questions for the chemical of interest, and guidance on how to assemble and integrate all lines of evidence (EDSP Tier 1 assays and OSRI, including peer reviewed studies) for that chemical. Thus, Tier 1 screening is combined with other relevant evidence (e.g., 40 CFR part 158 guideline studies) using a WoE analysis intended to determine whether or not a test chemical requires more comprehensive Tier 2 testing or a more targeted and tailored approach.

The Agency will present case studies based on a subset of List 1 chemicals for the Tier 1 test orders to illustrate the decision logic for applying EPA's EDSP WoE guidance (​#!documentDetail;​D=​EPA-HQ-OPPT-2010-0877-0021) in interpreting Tier 1 screening results and OSRI. The FIFRA SAP will be asked to comment on interpretative issues that arise during this WoE approach as well as the decision logic that guides the determination of whether higher level testing is needed.
