    SUPPLEMENTARY INFORMATION: EPA issued a notice, published in the 
    Federal Register of May 5, 1993 (58 FR 26687), which announced the 
    establishment of a 3-year time-limited tolerance for residues of the 
    insecticidal fluorine compounds cryolite and synthetic cryolite (sodium 
    aluminum fluoride) on potatoes and the establishment of a 3-year time-
    limited feed additive regulation for residues of these compounds in 
    processed potato waste (wet or dry).
        These regulations were established for a period extending to May 6, 
    1996, to cover residues existing from the conditional registration of 
    the insecticidal compounds on potatoes extending to September 30, 1995. 
    The Agency limited the period of time the conditional registration and 
    the regulations were to be in effect because of the lack of a chronic 
    dog feeding study and a two-generation rat reproduction study. These 
    two studies have been received and have been found to be acceptable.
        Pesticide petition 9F3739 requests that the Administrator, pursuant 
    to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 
    21 U.S.C. 346a(d), amend 40 CFR 180 by establishing a tolerance for 
    residues of the insecticidal fluorine compounds in or on the raw 
    agricultural commodity potatoes at 2.0 ppm with no time limitations. 
    Food additive petition 1H5604 requests that the Administrator, pursuant 
    to section 409(b) of the FFDCA (21 U.S.C. 348), amend 40 CFR part 186 
    by establishing a feed additive regulation for residues of the 
    insecticidal compounds in or on the processed animal feed commodity 
    processed potato waste (wet or dry) at 22.0 ppm with no time 
    limitations.
        To meet the current definition, the commodity, ``processed potato 
    waste (wet or dry)'' is corrected to read as follows: potatoes, waste 
    from processing.
    
    I. Background Information
    
        Fluoride has been identified as the residue of toxicological 
    concern in cryolite and synthetic cryolite and the available data show 
    that these compounds which are approximately 52.8% fluoride, act as 
    free fluoride. Fluoride is ubiquitous and may be present at low levels 
    in air, soils and in foodstuffs that have not been treated with 
    cryolite and/or synthetic cryolite as well as in drinking water. The 
    atmospheric levels of fluoride and incidental dietary exposures to 
    fluoride as a toothpaste additive or as a dental treatment contribute 
    relatively little to the average level of dietary fluoride exposure and 
    are not further considered in the exposure estimate.
        Data submitted in support of the subject petition show background 
    levels of fluoride in untreated potatoes ranged from 0.14 ppm to 0.31 
    ppm and are consistent with the ranges reported in the open literature. 
    Levels of fluoride found in the treated potatoes ranged from 0.18 ppm 
    to 0.94 ppm. The residue analytical method used for enforcing the 
    subject tolerance and regulation cannot distinguish between the 
    naturally occurring fluoride and the fluoride resulting from use of 
    cryolite and/or synthetic cryolite.
        Fluoride levels in public drinking water are regulated under the 
    Safe Drinking Water Act. EPA has established a Maximum Concentration 
    Limit (MCL) at 4.0 mg/L [0.114 mg/kg/day] to protect against crippling 
    skeletal fluorosis (51 FR 11396, April 2, 1986). The MCL established on 
    April 2, 1986, finalizes interim regulations set in November 14, 1985 
    (50 FR 47142), and proposed in the Federal Register of May 14, 1985 (50 
    FR 20164). In addition, these FR notices established a Secondary 
    Maximum Contaminant Level (SMCL) at 2.0 mg/L [0.057 mg/kg/day] for 
    cosmetic effects (objectionable dental fluorosis) which are not 
    considered to be adverse health effects by the Surgeon General.
        The EPA Office of Drinking Water issued a Drinking Water Criteria 
    Document on Fluoride (October 21, 1985) which presents summaries of 
    experimental and clinical data on the health effects of fluoride in 
    animals and humans. In general, the health effects of fluoride include 
    dental fluorosis and skeletal fluorosis.
    
        At the request of the EPA, the U.S. Surgeon General examined the 
    nondental health aspects associated with fluoride in drinking water. 
    The Surgeon General concluded that he did not consider changes in 
    bone density to be an adverse health effect and that adverse effects 
    (arthralgias) are not likely to occur at human dose levels below 20 
    mg F/day (10 mg F/L for an adult consuming 2 L water/day [0.29 mg/
    kg/day]). The ad hoc committee concluded that four times the optimal 
    fluoride concentration (approximately 4 mg F/L [0.114 mg/kg/day]) in 
    drinking water should provide an adequate margin of safety for 
    preventing adverse health effects which were not documented to occur 
    in the U.S. population below 8 mg F/L [0.23 mg/kg/day]. (Water 
    Criteria Document p. IX-21).
    
    [[Page 20783]]
    
    II. Toxicological Data
    
        The scientific data submitted in the petitions and other relevant 
    material have been evaluated. The toxicological data considered in 
    support of the proposed tolerance and regulation include:
        1. A 2-year rat bioassay conducted by the National Toxicology 
    Program (NTP) using sodium fluoride as the test material at dose levels 
    of 0, 25, 100, and 175 ppm, in water, representing 0, 1.3, 5.2 and 8.6 
    mg/kg/day in males and 0, 1.3, 5.5 and 9.5 mg/kg/day in females.
        Osteosarcoma of the bone was only observed in one male in the 100 
    ppm group and in three males in the 175 ppm group. NTP considers this 
    to be equivocal evidence of carcinogenicity in male F344/N rats. The 
    NOEL is less than 25 ppm (1.3 mg/kg/day). The LOEL is 25 ppm (1.3 mg/
    kg/day) based on mottling of teeth, dentine incisor dysplasia, 
    increased serum, urine and bone fluoride levels in males and females 
    and incisor odontoblast and incisor ameloblast degeneration in males. 
    There was ``equivocal evidence'' of carcinogenic activity in male rats 
    and ``no evidence'' of carcinogenic activity in female rats.
        The NTP study utilizing sodium fluoride as the test material in 
    lieu of cryolite or synthetic cryolite satisfies the guideline study 
    requirement for both the rodent chronic feeding study and the rat 
    carcinogenicity study. Fluoride has been identified as the residue of 
    toxicological concern in cryolite and synthetic cryolite and the 
    available data show that these compounds act as free fluoride.
        2. A 2-year mouse bioassay conducted by the NTP utilizing sodium 
    fluoride as the test material at dose levels of 0, 25, 100, and 175 
    ppm, in water, representing 0, 2.4, 9.6 and 16.7 mg/kg/day in males and 
    0, 2.8, 11.3 and 18.8 mg/kg/day in females.
        The NOEL is less than 25 ppm (2.4 mg/kg/day). The LOEL is 25 ppm 
    (2.4 mg/kg/day) based on attrition of the teeth in males, discoloration 
    and mottling of the teeth in males and females and increased bone 
    fluoride in both sexes. There was ``no evidence'' of carcinogenic 
    activity in male and female mice.
        This study utilizing sodium fluoride in lieu of cryolite or 
    synthetic cryolite as the test material satisfies the guideline study 
    requirement for a mouse carcinogenicity study for the reason described 
    above under item one.
        3. A 1-year chronic dog feeding study conducted with cryolite at 
    dose levels of 0, 3,000, 10,000 and 30,000 ppm, representing 0, 95, 366 
    and 1,137 mg/kg/day in males and 0, 105, 387 and 1139 mg/kg/day in 
    females (in terms of fluoride the doses are 0, 51, 198, and 614 mg F/
    kg/day for males and 0, 57, 209 and 615 mg F/kg/day for females).
        The NOEL (in terms of cryolite) is less than 3,000 ppm (95 mg/kg/
    day in males and 105 mg/kg/day in females). The LOEL is 3,000 ppm (95 
    mg/kg/day) based on increases in emesis, nucleated cells in males, 
    renal lesions and a decrease in urine specific gravity in females.
        4. A two-generation reproduction study conducted with cryolite in 
    the diet of rats at dose levels of 0, 200, 600, and 1,800 ppm 
    (representing 0, 14, 42, and 128 mg/kg/day for males and 0, 16, 49, and 
    149 mg/kg/day for females, respectively, during premating).
        The systemic toxicity NOEL was not determined. The LOEL for 
    systemic toxicity was 200 ppm (15 mg/kg/day) based on dental fluorosis. 
    The NOEL and LOEL for reproductive toxicity were 600 and 1,800 ppm, 
    respectively (46 and 138 mg/kg/day) based on decreased pup body 
    weights.
        5. A developmental toxicity study conducted with cryolite in rats 
    at dose levels of 0, 750, 1,500, and 3,000 mg/kg/day (gavage). The NOEL 
    for both developmental and maternal toxicity is 3,000 mg/kg/day. At 
    this dose level, the only observation was whitening of the teeth of 
    dams.
        6. A developmental toxicity study conducted in female mice with 
    cryolite at dose levels of 0, 30, 100 and 300 mg/kg/day (gavage).
        The NOEL for maternal toxicity is 30 mg/kg/day and the LOEL is 100 
    mg/kg/day based on the occurrence of dark red contents of the stomach.
        Fetuses at 300 mg/kg/day exhibited bent ribs and bent limb bones. 
    The NOEL for developmental toxicity is 100 mg/kg/day. The LOEL is 300 
    mg/kg/day based on an increase in bent ribs and bent limbs.
        7. A range-finding developmental toxicity study conducted in female 
    rabbits with cryolite at dose levels of 0, 10, 30, 100, 300 and 1,000 
    mg/kg/day (gavage).
        The NOEL for maternal toxicity is 10 mg/kg/day and the LOEL is 30 
    mg/kg/day based on an increased incidence of soft stool and dark 
    colored feces and decreased defecation and urination. The NOEL for 
    developmental toxicity is 30 mg/kg/day. The LOEL could not be assessed 
    due to excessive toxicity at dose levels of 30 mg/kg/day.
        This study suggested that severe maternal toxicity occurred at 
    lower doses than external developmental toxicity. However, following an 
    extensive literature evaluation, the National Research Council 
    (National Academy of Sciences Subcommittee of Health Effects of 
    Ingested Fluoride) (NAS) determined that,
    
        There have been reports of adverse effects on reproductive 
    outcomes associated with high levels of fluoride intake in many 
    animal species. In most of the studies, however, the fluoride 
    concentrations associated with adverse effects were far higher than 
    those encountered in drinking water. . . .
        Based on these findings, the subcommittee concludes that the 
    fluoride concentrations associated with adverse reproductive effects 
    in animals are far higher than those to which human populations are 
    exposed. Consequently, ingestion of fluoride at current 
    concentrations should have no adverse effects on human reproduction.
    
        Therefore, an additional developmental study in rabbits is not 
    required.
        8. A 28-day range-finding feeding study conducted with cryolite in 
    rats at dose levels of 0, 250, 500, 1,000, 2,000, 4,000, 10,000, 25,000 
    and 50,000 ppm in the diet (representing approximately 0, 25, 50, 100, 
    200, 400, 1,000, 2,500 and 5,000 mg/kg/day) with the only compound 
    related effect being a change in coloration and physical property of 
    the teeth.
        The NOEL was not determined. The LOEL is 250 ppm (25 mg/kg/day) 
    based on dental fluorosis.
        9. A 90-day rat feeding study conducted with cryolite at dose 
    levels of 0, 50, 5,000, and 50,000 ppm (corresponding to 0, 3.8, 399.2 
    and 4,172.3 mg/kg/day in males and 0, 4.5, 455.9 and 4,758.1 mg/kg/day 
    in females).
        The NOEL is 50 ppm (3.8 mg/kg/day) for effects other than fluoride 
    accumulation. The LOEL is 5,000 ppm (399.2 mg/kg/day) based on lesions 
    observed in the stomach. Fluoride accumulated at all dose levels.
        10. A 90-day dog feeding study conducted with cryolite at dose 
    levels of 0, 500, 10,000, and 50,000 ppm (corresponding to 0, 17, 368 
    and 1,692 mg/kg/day).
        The NOEL is 10,000 ppm (368 mg/kg/day). The LOEL is 50,000 ppm 
    (1,692 mg/kg/day) for effects other than fluoride accumulation. 
    Fluoride accumulation occurred at all dose levels.
        11. Genotoxicity studies including an Ames test (negative) at dose 
    levels of 167, 500, 1,670, 5,000, 7,500 and 10,000 ug/plate; an in 
    vitro assay in human lymphocytes (negative) at 100, 500, and 1,000 ug/
    ml; and an unscheduled DNA synthesis study in rat hepatocytes 
    (negative) at dose levels up to and including 50 ug/ml.
        12. Open literature studies showing that human and animal 
    metabolism of
    
    [[Page 20784]]
    
    cryolite and/or synthetic cryolite manifests itself as normal free 
    fluoride metabolism. That is, dissociation occurs, producing free 
    fluoride ions which are assimilated into bone.
        The available toxicity data are considered adequate to support the 
    proposed regulations to establish maximum permissible levels for 
    residues of the insecticidal fluorine compounds in or on potatoes and 
    in processed potato waste.
        The available information does not support the regulation of the 
    cryolite insecticides as carcinogens.
        Fluoride has been the subject of a comprehensive review by the 
    National Research Council (National Academy of Sciences Subcommittee of 
    Health Effects of Ingested Fluoride) who concluded that ``. . . the 
    available laboratory data are insufficient to demonstrate a 
    carcinogenic effect of fluoride in animals.'' and that ``. . . the 
    weight of evidence from more than 50 epidemiological studies does not 
    support the hypothesis of an association between fluoride exposure and 
    increased cancer risk in humans.'' EPA is in agreement with the 
    conclusions reached by the National Academy of Science (NAS).
        Rather than the establishment of the traditional Reference Dose 
    (RfD), a weight-of-the-evidence risk assessment was determined by the 
    Agency to be a more appropriate approach for the assessment of the 
    dietary exposure to fluoride residues as a result of agricultural uses 
    of cryolite for the following reasons:
          National and international regulatory organizations (U.S. 
    EPA Office of Water, U.S. DHHS, the Canadian Government, and the World 
    Health Organization) have assessed potential health risks from exposure 
    to fluoride. The endpoints and estimated effect levels documented by 
    these organizations are similar.
          The U.S. Surgeon General (Koop, 1984 and Elders, 1994) 
    has recommended a guideline level of exposure that should provide an 
    adequate ``margin of safety'' based on a large amount of human data, 
    including epidemiology studies.
          Animal data considered in evaluating the proposed 
    regulations are consistent with human data with respect to dose-related 
    skeletal effects.
        The weight-of-the-evidence dietary risk assessment was conducted 
    utilizing the following factors. All calculations are based on 2 L/day 
    water consumption and 70 kg adult.
          There exists no directly applicable scientific 
    documentation of adverse medical effects at levels of fluoride below 8 
    mg/L [0.23 mg/kg/day]. (U.S. EPA. 1985. National Primary Drinking Water 
    Regulations; Fluoride. Proposed Rulemaking. (50 FR 20166, May 14, 
    1985).
          Less than 0.4% of the U.S. population (on public water 
    supplies) is exposed to greater than 2 mg/L fluoride [0.057 mg/kg/day] 
    in the public water supply. (U.S. EPA. 1985. Drinking Water Criteria 
    Document on Fluoride. U.S. EPA Office of Drinking Water, Washington, 
    D.C. TR-832-5. pg. IV-3, Table IV-1.)
          Dietary exposure estimates using reassessed tolerances 
    including the subject proposed tolerance and regulation for potatoes 
    and percent of crops treated are approximately 0.029 mg/kg/day for the 
    U.S. population and 0.038 mg/kg/day for the highest exposed subgroup 
    (females 20 years old and over).
        Therefore, it can be concluded that levels of fluoride in/on food 
    from the agricultural use of cryolite plus fluoride levels in U.S. 
    drinking water supplies results in a daily dietary intake of fluoride 
    of approximately 0.095 mg/kg/day. This is less than the Maximum 
    Concentration Limit (MCL) of 4.0 mg/L [0.114 mg/kg/day], a level which 
    provides no known or anticipated adverse health effect as determined by 
    the Surgeon General.
        The estimated dietary exposure resulting from the subject proposed 
    tolerance on potatoes is approximately 0.00016 mg/kg/day.
        The metabolism of the subject insecticides in plants and animals is 
    adequately understood. Plant residues are inorganic surface residues of 
    cryolite which are measured as total fluoride. Cryolite metabolism in 
    animals manifests itself as free fluorine metabolism and the residue of 
    concern in animals is total fluoride.
        An adequate analytical method (fluoride specific electrode) is 
    available for enforcement purposes for the RAC potatoes and the animal 
    feed, potato waste. Because the subject compounds are inorganic 
    compounds, the requirement for data using the multiresidue protocols in 
    PAM Vol. I is not applicable.
        Because of the long lead time from establishing this tolerance and 
    regulation to publication of the enforcement methodology in the 
    Pesticide Analytical Manual, Vol. II, the analytical methodology is 
    being made available in the interim to anyone interested in pesticide 
    enforcement when requested from: Calvin Furlow, Public Information 
    Branch, Field Operations Division (H7506C), Office of Pesticide 
    Programs, Environmental Protection Agency, 401 M St., SW., Washington, 
    DC 20460. Office location and telephone number; Rm. 1128, CM #2, 1921 
    Jefferson Davis Hwy., VA 22202, (703)-305-5232.
        There is no reasonable expectation of finite residues of cryolite 
    or synthetic cryolite occurring in the meat, milk, poultry, and eggs of 
    animals fed potato waste resulting from the processing of treated 
    potatoes and 40 CFR 180.6(a)(3) applies. Thus, secondary tolerances are 
    not necessary at this time in meat, milk, poultry, and eggs.
        There are presently no actions pending against the continued 
    registration of these insecticidal compounds.
        The pesticide is considered useful for the purpose for which the 
    tolerance is sought and capable of achieving its physical or technical 
    effect.
        Based on the information and data considered, the Agency has 
    determined that the tolerance established by amending 40 CFR part 180 
    would protect the public health, and the establishment of a feed 
    additive regulation by amending 40 CFR part 186 would be safe. 
    Therefore, it is proposed that they be established as set forth below.
        Any person who has registered or submitted an application for 
    registration of a pesticide, under the Federal Insecticide, Fungicide, 
    and Rodenticide Act (FIFRA) as amended, which contains any of the 
    ingredients listed herein, may request within 30 days after publication 
    of this notice in the Federal Register that this rulemaking proposal as 
    it relates to the section 408 tolerance be referred to an Advisory 
    Committee in accordance with section 408(e) of the FFDCA.
        Interested persons are invited to submit written comments on the 
    proposed regulation. Comments must bear a notation indicating the 
    document control number, PP 9F3739 and FAP 1H5604/P. All written 
    comments filed in response to this petition will be available in the 
    Public Response and Program Resources Branch at the above address from 
    8 a.m. to 4:30 p.m., Monday through Friday, except legal holidays.
        A record has been established for this proposal under docket number 
    (PP 9F3739 and FAP 1H5604/P654) (including comments and data submitted 
    electronically as described below). A public version of this record,

        Electronic comments can be sent directly to EPA at:
        opp-docket@epamail.epa.gov
    
        Electronic comments must be submitted as an ASCII file avoiding the 
    use of special characters and any form of encryption.
        The official record for this proposal, as well as the public 
    version, as described above will be kept in paper form. Accordingly, 
    EPA will transfer all comments received electronically into printed, 
    paper form as they are received and will place the paper copies in the 
    official rulemaking record which will also include all comments 
    submitted directly in writing. The official rulemaking record is the 
    paper record maintained at the address in ADDRESSES at the beginning of 
    this document.
        Under Executive Order 12866 (58 FR 51735, October 4, 1993), the 
    Agency must determine whether the regulatory action is ``significant'' 
    and therefore subject to all the requirements of the Executive Order 
    (i.e., Regulatory Impact Analysis, review by the Office of Management 
    and Budget (OMB)). Under section 3(f), the order defines 
    ``significant'' as those actions likely to lead to a rule (1) having an 
    annual effect on the economy of $100 million or more, or adversely and 
    materially affecting a sector of the economy, productivity, 
    competition, jobs, the environment, public health or safety, or State, 
    local or tribal governments or communities (also known as 
    ``economically significant''); (2) creating serious inconsistency or 
    otherwise interfering with an action taken or planned by another 
    agency; (3) materially altering the budgetary impacts of entitlement, 
    grants, user fees, or loan programs; or (4) raising novel legal or 
    policy issues arising out of legal mandates, the President's 
    priorities, or the principles set forth in this Executive Order.
        Pursuant to the terms of this Executive Order, EPA has determined 
    that this rule is not ``significant'' and is therefore not subject to 
    OMB review.
        In addition, this action does not impose any enforceable duty, or 
    contain any ``unfunded mandates'' as described in Title II of the 
    Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4), or require prior 
    consultation as specified by Executive Order 12875 (58 FR 58093, 
    October 28, 1993), entitled Enhancing the Intergovernmental 
    Partnership, or special consideration as required by Executive Order 
    12898 (59 FR 7629, February 16, 1994).
        Pursuant to the requirements of the Regulatory Flexibility Act 
    (Pub. L. 96-354, 94 Stat. 1164, 5 U.S.C. 601-612), the Administrator 
    has determined that regulations establishing new tolerances or raising 
    tolerance levels or establishing exemptions from tolerance 
    requirements, or establishing or raising food additive regulations do 
    not have a significant economic impact on a substantial number of small 
    entities. A certification statement to this effect was published in the 
    Federal Register of May 4, 1981 (46 FR 24950).
