         EPA's position paper, charge/questions to FIFRA SAP, FIFRA SAP composition (i.e., members and consultants for this meeting), and the meeting agenda will be available as soon as possible, but no later than mid-to late May 2005. In addition, the Agency may provide additional background documents as the materials become available. You may obtain electronic copies of these documents, and certain other related documents that might be available electronically, from the FIFRA SAP Internet Home Page at http://www.epa.gov/scipoly/sap.

         An electronic version of the public docket is available through EPA's electronic public docket and comment system, EPA Dockets. You may use EPA Dockets at http://www.epa.gov/edocket/ to submit or view public

         comments, access the index listing of the contents of the official public docket, and to access those documents in the public docket that are available electronically. Once in the system, select ``search,'' then key in the appropriate docket ID number.

         Certain types of information will not be placed in EPA Dockets. Information claimed as CBI and other information whose disclosure is restricted by statute, which is not included in the official public docket, will not be available for public viewing in EPA's electronic public docket. EPA's policy is that copyrighted material will not be placed in EPA's electronic public docket but will be available only in printed, paper form in the official public docket. To the extent feasible, publicly available docket materials will be made available in EPA's electronic public docket. When a document is selected from the index list in EPA Dockets, the system will identify whether the document is available for viewing in EPA's electronic public docket. Although not all docket materials may be available electronically, you may still access any of the publicly available docket materials through the docket facility identified in Unit I.B.1. EPA intends to work towards providing electronic access to all of the publicly available docket materials through EPA's electronic public docket.

         For public commenters, it is important to note that EPA's policy is that public comments, whether submitted electronically or in paper, will be made available for public viewing in EPA's electronic public docket as EPA receives them and without change, unless the comment contains copyrighted material, CBI, or other information whose disclosure is restricted by statute. When EPA identifies a comment containing copyrighted material, EPA will provide a reference to that material in the version of the comment that is placed in EPA's electronic public docket. The entire printed comment, including the copyrighted material, will be available in the public docket.

         Public comments submitted on computer disks that are mailed or delivered to the docket will be transferred to EPA's electronic public docket. Public comments in hard copy that are mailed or delivered to the docket will be scanned and placed in EPA's electronic public docket. Where practical, physical objects will be photographed, and the photograph will be placed in EPA's electronic public docket along with a brief description written by the docket staff.

   3. How and to Whom Do I Submit Comments?

      You may submit comments electronically (preferred), through hand delivery/courier, or by mail. To ensure proper receipt by EPA, identify the appropriate docket ID number in the subject line on the first page of your comment. Please ensure that your comments are submitted within the specified comment period. Comments received after the close of the comment period will be marked ``late.'' EPA is not required to consider these late comments. Do not use EPA Dockets or e-mail to submit CBI or information protected by statute.

      1. Electronically. If you submit an electronic comment as prescribed in this unit, EPA recommends that you include your name, mailing address, and an e-mail address or other contact information in the body of your comment. Also include this contact information on the outside of any disk or CD ROM you submit, and in any cover letter accompanying the disk or CD ROM. This ensures that you can be identified as the submitter of the comment and allows EPA to contact you in case EPA cannot read your comment due to technical difficulties or needs further information on the substance of your comment. EPA's policy is that EPA will not edit your comment, and any identifying or contact information provided in the body of a comment will be included as part of the comment that is placed in the official public docket, and made available in EPA's electronic public docket. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment.

         i. EPA Dockets. Your use of EPA's electronic public docket to submit comments to EPA electronically is EPA's preferred method for receiving comments. Go directly to EPA Dockets at http://www.epa.gov/edocket/ , and follow the online instructions for submitting comments.

         Once in the system, select ``search,'' and then key in docket ID number OPP-2005-0102. The system is an ``anonymous access'' system, which means EPA will not know your identity, e-mail address, or other contact information unless you provide it in the body of your comment.

         ii. E-mail. Comments may be sent by e-mail to opp-docket@epa.gov, Attention: Docket ID Number OPP-2005-0102. In contrast to EPA's electronic public docket, EPA's e-mail system is not an ``anonymous access'' system. If you send an e-mail comment directly to the docket without going through EPA's electronic public docket, EPA's e-mail system automatically captures your e-mail address. E-mail addresses that are automatically captured by EPA's e-mail system are included as part of the comment that is placed in the official public docket, and made available in EPA's electronic public docket.

         iii. Disk or CD ROM. You may submit comments on a disk or CD ROM that you deliver as described in Unit I.C.2 or mail to the address provided in Unit I.C.3. These electronic submissions will be accepted in WordPerfect or ASCII file format. Avoid the use of special characters and any form of encryption.

      2. By hand delivery or courier. Deliver your comments to: Public Information and Records Integrity Branch (PIRIB), Office of Pesticide Programs (OPP), Environmental Protection Agency, Rm. 119, Crystal Mall 2, 1801 South Bell St., Arlington, VA, Attention: Docket ID

         [[Page 21748]]

         Number OPP-2005-0102. Such deliveries are only accepted during the docket's normal hours of operation as identified in Unit I.B.1.

      3. By mail. Due to potential delays in EPA's receipt and processing of mail, respondents are strongly encouraged to submit comments either electronically or by hand delivery or courier. We cannot guarantee that comments sent via mail will be received prior to the close of the comment period. If mailed, please send your comments to: Public Information and Records Integrity Branch (PIRIB) (7502C), Office of Pesticide Programs (OPP), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001, Attention: Docket ID Number OPP-2005-0102.

      4. Provide specific examples to illustrate your concerns.

      5. Make sure to submit your comments by the deadline in this document.

      6. To ensure proper receipt by EPA, be sure to identify the docket ID number assigned to this action in the subject line on the first page of your response. You may also provide the name, date, and Federal Register citation.

   5. How May I Participate in this Meeting?

      You may participate in this meeting by following the instructions in this unit. To ensure proper receipt by EPA, it is imperative that you identify docket ID number OPP-2005-0102 in the subject line on the first page of your request.

      1. Oral comments. Oral comments presented at the meetings should not be repetitive of previously submitted oral or written comments. Although requests to present oral comments are accepted until the date of the meeting (unless otherwise stated), to the extent that time permits, interested persons may be permitted by the Chair of FIFRA SAP to present oral comments at the meeting. Each individual or group wishing to make brief oral comments to FIFRA SAP is strongly advised to submit their request to the DFO listed under FOR FURTHER INFORMATION CONTACT no later than noon, eastern time, June 7, 2005, in order to be included on the meeting agenda. 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 30 copies of his or her comments and presentation slides for distribution to FIFRA SAP at the meeting.

      2. Written comments. Although written comments are accepted until the date of the meeting (unless otherwise stated), the Agency encourages that written comments be submitted, using the instructions in Unit I.C., no later than noon, eastern time, May 31, 2005, to provide FIFRA SAP the time necessary to consider and review the written comments. The DFO listed under FOR FURTHER INFORMATION CONTACT should be notified that comments have been submitted to the docket or a courtesy copy of the comments should be provided to the DFO. There is no limit on the extent of written comments for consideration by FIFRA SAP.

      3. Seating at the meeting. Seating at the meeting will be on a first-come basis. Individuals requiring special accommodations at this meeting, including wheelchair access and assistance for the hearing impaired, should contact the DFO at least 5 business days prior to the meeting using the information under FOR FURTHER INFORMATION CONTACT so that appropriate arrangements can be made.

      4. Request for nominations of prospective candidates for service as ad hoc members of the FIFRA SAP for this meeting. As part of a broader process for developing a pool of candidates for each meeting, the FIFRA SAP staff routinely solicit the stakeholder community for nominations of prospective candidates for service as ad hoc members of the 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: cholinesterase inhibition and recovery, pharmacokinetics/pharmocodynamics, statistics, exposure modeling. Nominees should be scientists who have sufficient professional qualifications, including training and experience, to be capable of providing expert comments on 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 9, 2005. 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 the 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. Though 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 the 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 10 ad hoc scientists.

      If a prospective candidate for service on the FIFRA SAP is considered for participation in a particular session, the candidate is subject to the provisions of 5 CFR part 2634, Executive Branch Financial Disclosure, as supplemented by the EPA in 5 CFR part 6401. As such, the FIFRA SAP candidate is required to submit a Confidential Financial Disclosure Form for Special Government Employees Serving on Federal Advisory Committees at EPA (EPA Form 3110-48 5-02) 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 candidate's

      [[Page 21749]]

      financial disclosure form to assess that there are no financial conflicts of interest, no appearance of lack of impartiality and no prior involvement with the development of the documents under consideration (including previous scientific peer review) before the candidate is considered further for service on the 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 or may be obtained by contacting the PIRIB at the address or telephone number listed in Unit I.

2. Background

   1. Purpose of the FIFRA SAP

      Amendments to FIFRA enacted November 28, 1975 (7 U.S.C. 136w(d)), include a requirement under section 25(d) of FIFRA that notices of intent to cancel or reclassify pesticide registrations pursuant to section 6(b)(2) of FIFRA, as well as proposed and final forms of regulations pursuant to section 25(a) of FIFRA, be submitted to a SAP prior to being made public or issued to a registrant. In accordance with section 25(d) of FIFRA, the FIFRA SAP is to have an opportunity to comment on the health and environmental impact of such actions. The FIFRA SAP also shall make comments, evaluations, and recommendations for operating guidelines to improve the effectiveness and quality of analyses made by Agency scientists. Members are scientists who have sufficient professional qualifications, including training and experience, to be capable of providing expert comments as to the impact on health and the environment of regulatory actions under sections 6(b) and 25(a) of FIFRA. The Deputy Administrator appoints seven individuals to serve on the FIFRA SAP for staggered terms of 4 years, based on recommendations from the National Institutes of Health and the National Science Foundation. Section 104 of FQPA (Public Law 104-170) established the FQPA Science Review Board (SRB). These scientists shall be available to the FIFRA SAP on an ad hoc basis to assist in reviews conducted by the FIFRA SAP.

   2. Public Meeting

      Acute dietary exposure to pesticides is currently assessed using probabilistic models (DEEM-FCID, LifeLine, CARES) that combine the entire distributions of consumption and residue data. These models perform exposure assessments using total daily 24 hour consumption amounts. It is known, however, that the acute toxic effects of certain classes of chemicals are rapidly reversible. In the case of cholinesterase inhibition by carbamates, reversibility occurs within minutes to hours. Thus, the effect of exposure to carbamates should be assessed using consumption data that refer to single eating occasions, or shorter periods of time (less than 24 hours) to reflect the toxicology profiles of these compounds. The FIFRA Scientific Advisory Panel (February 1999) concurred with the validity of using the time- dependent recovery of acetylcholinesterase to assess risks from repeated exposures to aldicarb.

      Recent advances in modeling have provided the capability to conduct exposure modeling in periods less than 24 hours. Two modules, designed for compatibility with the CARES model maintained by the International Life Sciences Institute, will be presented. The first module, referred to as the Dietary Minute Module (DMM) allocates daily consumption amount for an individual by minute of a day as recorded in the CSFII database. A user determined elapsed time interval is then applied that reflects the reversibility of cholinesterase activity for the carbamate of interest based on pharmacodynamic or toxicological studies. The time entered defines discrete eating occasions for an individual's day. Each discrete eating occasion ends when a period of consumption is followed by an elapsed time interval in which no consumption of carbamate residues has occurred. A distribution of exposure for all individuals' discrete eating occasions within a day for all days and individuals in the population of interest is then created. The second module, referred to as the Cholinesterase Activity Module (CAM), is a refinement of the DMM. It incorporates the time course for reversibility of exposure to an acetylcholinesterase inhibitor, rather than assuming a fixed elapsed time period. Time dependent changes in exposure are determined from corresponding changes in acetylcholinesterase activity. A more realistic estimate of exposure can then be calculated from a summation of residual activity from all eating events.

   3. FIFRA SAP Meeting Minutes

      The FIFRA SAP will prepare meeting minutes summarizing its recommendations to the Agency in approximately 90 days after the meeting. The meeting minutes will be posted on the FIFRA SAP web site or may be obtained by contacting the PIRIB at the address or telephone number listed in Unit I.
