3. Seating at the meeting. Seating at the in-person meeting will be open and on a first-come basis.
4. Request for nominations to serve as ad hoc expert 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: (i) Development and implementation of new approach methodologies (NAMs); (ii) inhalation alternative testing; (iii) inhalation toxicology; (iv) inhalation exposure assessment; (v) inhalation/computational fluid dynamic (CFD) modeling; and (vi) risk assessment. Nominees should be scientists who have sufficient professional qualifications, including training and experience, to provide expert comments on the scientific issues for this meeting. Nominees should be identified by name, occupation, position, address, email address, and telephone number. Nominations should be provided to the Start Printed Page 39089DFO listed under FOR FURTHER INFORMATION CONTACT on or before September 7, 2018. The Agency will consider all nominations of prospective candidates for this meeting that are received on or before that 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 EPA. Other factors considered during the selection process include availability of the potential Panel member to fully participate in the Panel's review, absence of any conflicts of interest or appearance of loss of impartiality, independence with respect to the matters under review, and lack of bias. Although financial conflicts of interest, the appearance of loss 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 peer review charge for this meeting, the Agency anticipates selecting approximately 13 ad hoc scientists.
FIFRA SAP members are subject to the provisions of 5 CFR part 2634—Executive Branch Financial Disclosure, Qualified Trusts, and Certificates of Divestiture, as supplemented by EPA in 5 CFR part 6401. In anticipation of this requirement, prospective candidates for service on 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. EPA will evaluate the candidate's financial disclosure form to assess whether there are financial conflicts of interest, appearance of a loss 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 and final report. The list of FIFRA SAP members participating at this meeting will be posted on the FIFRA SAP website at http://www.epa.gov/scipoly/sap or may be obtained from the OPP Docket at http://www.regulations.gov.
A. Purpose of FIFRA SAP
The FIFRA SAP serves as one of the primary scientific peer review mechanisms of EPA's Office of Chemical Safety and Pollution Prevention (OCSPP) and is structured to provide independent scientific advice, information and recommendations to the EPA Administrator on pesticides and pesticide-related issues as to the impact of regulatory actions on human 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 (5 U.S.C. Appendix). The 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 (NIH) and the National Science Foundation (NSF). FIFRA established a Science Review Board (SRB) consisting of at least 60 scientists who are available to FIFRA SAP on an ad hoc basis to assist in reviews conducted by FIFRA SAP. As a scientific 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 conducts human health risk assessments to evaluate the potential health effects of pesticides and toxic chemicals in residential and occupational settings based on the use pattern or conditions of use. For evaluating effects via the inhalation route, registrants and manufacturers conduct subchronic inhalation toxicity studies according to test guideline requirements (OPPTS 870.3465, 40 CFR part 798, OECD TG 412 and 413). In these studies, several groups of experimental animals are exposed daily for a defined period to graduated concentrations of test substance as a gas or aerosol/particulate. These studies are used to determine a no observed adverse effect concentration (NOAEC) for effects following repeated inhalation exposure that may be used for human health risk assessment.
The anatomy and physiology of human and animal respiratory tracts differ in several ways that can impact changes in airflow and deposition of inhaled substances and, therefore, influence the animal to human dose response extrapolation. Furthermore, traditional in vivo toxicity tests used to extrapolate from test species to humans are expensive, time-consuming, and can cause stress to laboratory animals. As a result, efforts to develop alternative methods and strategies for evaluating toxic effects from inhaled chemicals using in vitro test systems with human tissues combined with human dosimetry modeling provide inherent advantages over using in vivo animal studies. These alternatives are also consistent with the National Research Council's (NRC) long-range vision to advance toxicity testing in the 21st century, as well as the strategic roadmap released by Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) to accomplish NRC's vision in the United States.
New approach methodologies (NAMs) has been adopted as a broadly descriptive reference to any non-animal technology, methodology, approach, or combination thereof that can be used to provide information on chemical hazard and risk assessment. An example of a NAM for refining inhalation risk assessment has been submitted to the Agency for the pesticide chlorothalonil. Chlorothalonil is a contact irritant that has been found to be toxic via the inhalation route. Due to the irritant nature of chlorothalonil and animal welfare concerns, the registrant (Syngenta Crop Protection) indicated that a 90-day inhalation toxicity study was not feasible to fulfill the regulatory requirement of a subchronic inhalation study. Subsequently, Syngenta proposed an alternative approach using an in vitro assay (MucilAirTM using human nasal tissue) to characterize the hazard of chlorothalonil and derive a point of departure (POD) for use in human health risk assessment. In order to calculate human equivalent concentrations for the purposes of human health risk assessment, an in Start Printed Page 39090vitro POD has been proposed in conjunction with surface concentrations of deposited chlorothalonil particles from a computational fluid dynamic (CFD) model for the upper airway of a human. As a proof of concept, Syngenta also used the calculated human equivalent concentrations for pesticide operators/applicators to provide potential risk estimates supported by this proposed approach.
The Agency is soliciting advice from the FIFRA Scientific Advisory Panel (SAP) on the derivation of the POD from the in vitro assay and the integration of the in vitro POD for calculation of human equivalent concentrations for the inhalation risk assessment. Chlorothalonil will be presented as a case study to solicit advice on the proposed overall approach expected to be applied to other pesticides or industrial chemicals in the future.
The 4-day, in-person FIFRA SAP meeting may also be webcast. You may refer to the FIFRA SAP website at http://www.epa.gov/sap for information on how to access the webcast.
