Suspensions of the test substance, Potassium Perfluorobutane Sulfonate (PFBS or T-7485), or the vehicle, aqueous 0.1YOcarboxymethylcellulose, were administered orally (gavage) once daily to these naturally-bred female rats on days 6 through 20 of presumed gestation (DGs 6 through 20) at dosages of 0 (Vehicle), 100,300, 1000 and 2000 mgikg/day. The dosage volume was 10 mL/kg, adjusted daily on the basis of the individual body weights recorded immediately before administration of the test substance or vehicle. * Checks for viability were made twice daily. Clinical observations were recorded daily before dosage, approximately 60 10 minutes after administration and on the day of sacrifice. Body weights were recorded daily during the dosage period and the day of sacrifice. Feed consumption values were recorded on DGs 0, 6, 9, 12, 15, 18 and 21. All rats were sacrificed on DG 2 1 and examined for the number and distribution of corpora lutea, implantation sites and uterine contents. The gravid uterus was excised and weighed. A gross necropsy of the thoracic, abdominal and pelvic viscera was performed. Fetuses were weighed and examined for gross external alterations and sex. All rats survived to scheduled sacrifice. Clinical observations considered test substancerelated were limited to urine-stained abdominal fur in four rats in the 2000 mg/kg/day dosage group. Persistent adverse clinical observations were confirmed at necropsy. No additional gross lesions were identified. Rats in the 2000 mg/kg/day dosage group lost weight on DGs 6 to 9 and body weight gains were reduced at several intervals tabulated during the dosage period. Reflecting these effects of the test substance, body weight gain was reduced in the 2000 mg/kg/day dosage group for the entire treatment (DGs 6 to 21) and gestation (DGs 0 to 2 1) periods. Absolute and relative feed consumption values were reduced in the 2000 mg/kg/day dosage group on DGs 6 to 9 , 9 to 12, 12 to 15, 15 to 18 and 18 to 21, and for the entire treatment and gestation periods. 4 18-023P:PAGE 6 Fetal body weights were reduced in the 2000 mg/kg/day dosage group, as compared with the control group. No other Caesarean-sectioning or litter parameters were affected by dosages of the test substance as high as 2000 mg/kg/day. No fetal gross alterations occurred. I. Purpose 418-023P:PAGE 7 The purpose of this study was to provide information for the selection of dosages to be used in the developmental toxicity (embryo-fetal toxicity and teratogenic potential) study of Potassium Perfluorobutane Sulfonate (PFBS) administered orally via gavage to Crl:CDB(SD)IGS BR VAF/PlusB presumed pregnant female rats. 11. Methodsa The test substance, Potassium Perfluorobutane Sulfonate (PFBS or T-7485), a white powder, was received on 14 December 2000, and was stored at room temperature. The vehicle, 0.19'0 carboxymethylcellulose (CMC, medium viscosity), was prepared using reverse osmosis membrane processed deionized water (R.O. deionized water). The carboxymethylcellulose, an off-white powder, was received from Sigma Chemical Company, St. Louis, Missouri, on 10 October 1999, and was stored at room temperature. Test substance and vehicle formulations were prepared approximately every 10 days and stored refrigerated (2OC to SOC). Results of the concentration, homogeneity and stability analyses are available in ATTACHMENT 2. The 10 and 30 mg/mL samples were all found to be within f 10% of the target concentrations; the 100 mg/mL samples were 88.9% and 105% of target and the 200 mg/mL samples were 99.2% and 76.8% of target. Forty presumed pregnant Crl:CDB(SD)IGS BR VAF/PlusB female rats were randomly assigned to five dosage groups (Groups I through V), eight rats per group. Suspensions of the test substance or the vehicle were administered orally (gavage) once daily to these naturally-bred female rats on days 6 through 20 of presumed gestation (DGs 6 through 20) at dosages of 0 (Vehicle), 100,300, 1000 and 2000 mg/kg/day. The dosage volume was 10 mL/kg, adjusted daily on the basis of the individual body weights recorded immediately before administration of the test substance or vehicle. Checks for viability were made twice daily. Clinical observations were recorded daily before dosage, approximately 60 f 10 minutes after administration and on the day of sacrifice. Body weights were recorded daily during the dosage period and the day of sacrifice. Feed consumption values were recorded on DGs 0 , 6 , 9 , 12, 15, 18 and 21. All rats were sacrificed on DG 2 1 and examined for the number and distribution of corpora lutea, implantation sites and uterine contents. The gravid uterus was excised and weighed. A gross necropsy of the thoracic, abdominal and pelvic viscera was performed. Fetuses were weighed and examined for gross external alterations and sex. a. Detailed descriptions of all procedures used in the conduct of this study are provided in the appropriate sections of this report and in the attached protocol and amendments. Deviations from the Protocol and the Standard Operating Procedures of the Testing Facility are available in the raw data. 111. Results 418-023P:PAGE 8 A. Mortality, Clinical and Necropsy Observations (Summary - Table 1; Individual Data - Tables 8 and 9) All rats survived to scheduled sacrifice. Clinical observations considered test substancerelated were limited to urine-stained abdominal fur in four rats in the 2000 mg/kg/day dosage group. Observations of red perinasal substance, red perioral substance, excess salivation and gasping in one rat in the 2000 mg/kg/day dosage group and localized alopecia on the limbs in one rat in the.300 mg/kg/day dosage group were not considered test substance related. Persistent adverse clinical observations were confirmed at necropsy. No additional gross lesions were identified. B. Maternal Body Weights, Body Weight Changes and Gravid Uterine Weights (Figure 1; Summaries - Tables 2 and 3; Individual Data - Table 10) Rats in the 2000 mg/kg/day dosage group lost body weight on DGs 6 to 9 and body weight gains were reduced at several intervals tabulated during the dosage period. Reflecting these effects of the test substance, body weight gain was reduced in the 2000 mg/kg/day dosage group for the entire treatment period (calculated as DGs 6 to 2 1) and the entire gestation period (calculated as DGs 0 to 21), compared to control group values. Gravid uterine weights were reduced (15.4%) for the rats in the 2000 mg/kg/day dosage group, compared to the control group. Reflecting this effect of the test substance, the corrected DG 2 1 body weight (DG 2 1 weight minus gravid uterine weight) was reduced (1 1.8%) in the 2000 mg/kg/day dosage group. Corrected body weight gain for the entire treatment period (calculated as DGs 6 to 2 1C) and the entire gestation period (calculated as DGs 0 to 21C) were also reduced in the 2000 mg/kg/day dosage group, compared to control group values. Body weights, body weight gains and gravid uterine weights were comparable in the 0 (Vehicle), 100,300 and 1000 rng/kg/day dosage groups. C. Maternal Absolute .(g/day) and Relative (g/kg/day) Feed Consumption Values (Summaries - Tables 4 and 5; Individual Data - Table 11) Absolute and relative feed consumption values were reduced in the 2000 mgikglday dosage group on DGs 6 to 9, 9 to 12, 12 to 15, 15 to 18 and 18 to 2 1, compared to control group values. Reflecting this effect of the test substance, absolute feed consumption values for the entire treatment period (calculated as DGs 6 to 21) were reduced (19.2%) and the entire gestation period (calculated as DGs 0 to 21) were reduced (16.4%), compared to control group values. Relative feed consumption values for the entire treatment period were reduced (13.7%) and the entire gestation period were reduced (1 1.3%), compared to control group values. 418-023P:PAGE 9 Absolute and relative feed consumption values were comparable in the 0 (Vehicle), 100, 300 and 1000 mg/kg/day dosage groups. D. Caesarean-Sectioning and Litter Observations (Summaries - Tables 6 and 7; Individual Data - Tables 12 through 14) Caesarean-sectioning observations were based on 8 (1OO%), 7 (87.5%),8 (loo%), 7 (87.5%)and 8 (100%) pregnant rats in the 0 (Vehicle), 100, 300, 1000 and 2000 mg/kg/day dosage groups, respectively. Male and female fetal body weights were reduced (12.2% and 13.0%, respectively), in the 2000 mg/kg/day dosage group, as compared with the control group. There were no other test substance-related effects on the following parameters evaluated at Caesarean-sectioning: litter averages for corpora lutea, implantations, litter sizes, live fetuses, early resorptions, percent resorbed conceptuses and percent live male fetuses. There were no dead fetuses or late resorptions, and no dams had whole litter resorptions. All placentae appeared normal. Totals of 121,96, 119, 101 and 118 live fetuses in the 0 (Vehcle), 100, 300, 1000 and 2000 mg/kg/day dosage groups, respectively, were examined externally for developmental alterations. No fetal gross alterations were identified. IV. Conclusion 418-023P:PAGE 10 Based on these data dosages of 0 (Vehicle), 100,300 and 1000mg/kg/day of PFBS are recommended for the developmental toxicity study in rats. The 100 mg/kg/day dosage is expected to be a no-observable-adverse-effect-level(NOAEL) for both maternal and embryo-fetal toxicity, and the 1000 mg/kg/day dosage is expected to produce minimal maternal toxicity and little or no developmental toxicity. an M.

All remaining bulk test substance will be returned to: 3M SMMG EHS&R 3M Center Building 236-16-10 St. Paul, MN 55144-1000 TEST SYSTEM: SpeciedStrain and Reason for Selection: The Crl:CD@(SD)IGS BR VAF/PIu@ rat w a s selected as the Test System because: 1) it is one mammalian species accepted and widely used throughout industry for nonclinical studies of developmentaltoxicity (embryo-fetal toxicity/teratogenicity); 2) this strain has been demonstrated to be sensitive to developmentaltoxins; and 3) historical data and experience exist at the Testing Number: Initial population acclimated: Population selected for study: 60 virgin female rats. 40 mated female rats (8 per dosage group). Bodv Weiqht and Aqe: Female rats will be ordered to have body weights of 200 g to 225 g each at receipt, at which time they will be expected to be at least 60 days of age. Actual body weights recordedthe day after receipt will be documented in the raw data. - Sex: Female rats will be given the test substance. Male rats of the same source and strain will be used only as breeders and are not considered part of the Test System. Source: 4 18-023P:PAGE47 Protocol 418-023P Page 7 Charles River Laboratories, Inc. The rats will be shipped in filtered cartons by air freight and/or truck from Charles River Laboratories, Inc., to the Testing Facility. Identification: Rats are permanently identified using MoneIGD self-piercing ear tags (Gey Band and Tag Co., Inc., No. MSPT 20101). Male rats are given unique permanent identification numbers upon assignment to the Testing Facility's breeder male rat population. Female rats are assigned temporary numbers at receipt and given unique permanent identification numbers when assigned to the study on the basis of day 0 of presumed gestation body weights. ANIMAL HUSBANDRY: All cage sizes and housing conditions are in compliance with the Guide for the Care and Use of Laboratory Housinq: The rats will be individually housed in stainless steel wire-bottomed cages except during the cohabitation period. During cohabitation, each pair of rats will be housed in the male rat's cage. No nesting materials will be supplied because the female rats will be sacrificed before parturition is expected. Room Air, Temperature and Humidity: The animal room is independently supplied with at least ten changes per hour of 100% fresh air that has been passed through 99.97% HEPA filters. Room temperature will be maintained at 64F to 79F (18C to 26C)and monitored constantly. Room humidity will also be monitored constantly and maintained at 30% to 70%. Liqht: An automatically-controlled 12-hour light: 12-hour dark fluorescent light cycle will be maintained. Each dark period will begin at 1900 hours EST. - Diet: Rats will be given Certified Rodent Dieto #5002 (PMI Nutrition International) available ad libitum from individual feeders. Water: 4 18-023P:PAGE 48 Protocol 418-023P Page 8 Water will be available ad libitum from individual bottles attached to the cages or from an automatic watering access system. All water will be from a local source and passed through a reverse osmosis membrane before use. Chlorine will be added to the processedwater as a bacteriostat; processedwater is expected to contain no more than 1.2 ppm chlorine at the time of analysis. Water is analyzed monthly for possible bacterial contaminationand twice annually for possible chemical contamination. Contaminants: Neither the Sponsor nor the Study Director is aware of any potential contaminants likely to be present in the certified diet or in the drinking water at levels that would interfere with the results of this study. Therefore, no analyses other than those routinely performed by the feed supplier or those mentioned in this protocol will be conducted. RANDOMlZATlON AND COHABITATION: Upon arrival, male and female rats will be assigned to individual housing on the basis of computer-generatedrandom units. After acclimation, virgin female rats will be cohabited with breeder male rats, one male rat per female rat. The cohabitation period will consist of a maximum of five days. Female rats with spermatozoa observed in a smear of the vaginal contents andlor a copulatory plug observed in situ will be considered to be at day 0 of presumed gestation and assigned to individual housing. Healthy mated female rats will be assigned to dosage groups based on computergenerated (weight-ordered) randomization procedures. ADMINISTRATION: Route and Reason for Choice: The oral (gavage) route was selected for use because: 1) in comparison with the dietary route, the exact dosage can be accurately administered; and 2) it is one possible route of human exposure. Method and Frequency: Female rats will be given the test substance once daily on days 6 through 20 of presumed gestation. Dosages will be adjusted daily for body weight changes and given at approximately the same time each day. Rationale for Dosaqe Selection: 4 18-023P:PAGE 49 Protocol 418-023P Page 9 Dosages were selected on the basis of a 28-day (gavage) study of T-7485 in rats (Redfield Laboratories Study Number 132-007)with an approximate 14-day recovery period which resulted in no mortality or abnomal clinical observations as well as no changes in body weights, body weight changes, feed consumption, peripheral neuropathy, motor activity, audio/visual response, hematology,clinical chemistry, gross pathology and histopathology. The administration of 900 mg/kg/day T-7485 resulted in significant increases in male liver and female kidney weights when compared to control animals and establishes the no-observable-adverse-effect-level(NOAEL) at 300 mg/kg/day T-7485. The highest dosage level selected should induce some overt developmental and/or maternal mortality. The intermediate dosage levels should produce minimal observed toxic effects. The lowest dosage level should not produce any evidence of either maternal or developmental toxicity.

Clinical Observations and/or General Appearance: Acclimation Period: Weekly. Predosage Period: Day 0 of presumed gestation. I Dosage Period: Daily before dosage. Postdosage observations will be recorded approximately 60+10 minutes after administration. Day of Sacrifice: Once. 418-023P:PAGE 50 Protocol 418-023P Page 10 Clinical observations may be recorded more frequently than cited above, if deemed appropriate by the Study Director and/or Study Monitor. Bodv Weiqhts: Acclimation Period: Weekly. Predosage Period: Day 0 of presumed gestation. Dosage Period: Daily. Day of Sacrifice: Prior to sacrifice. Feed Consumption Values (recorded and tabulated): Predosage Period: Dosage Period: Day 0 of presumed gestation. Days 6, 9 12, 15, 18 and 21 of presumed gestation. Day of Sacrifice: Feed left recorded. Feed consumption values may be recorded more frequently if it is necessary to replenish the feed. These intervals will not be tabulated. Matinq Performance: Mating will be evaluated daily during the cohabitation period and confirmed by observation of spermatozoa in a smear of the vaginal contents and/or a copulatory plug observed in situ. Caesarean-Sectioninq Observations: Rats will be Caesarean-sectionedon day 21 of presumed gestation. To minimize bias, Caesarean-sectioning and subsequent fetal observationswill be conducted without knowledge of dosage group. The gravid uterus will be excised and weighed. The fetuses will be removed from the uterus and placed in individual containers. The rats will be examined for number and distribution of: Corpora Lutea. Implantation Sites. 4 18-023P:PAGE 5 1 Protocol 418-023P Page 11 Live and Dead Fetuses. (A live fetus is defined as one that responds to stimuli; a dead fetus is defined as a term fetus that does not respond to stimuli and that is not markedly autolyzed; dead fetuses demonstrating marked to extreme autolysis are considered to be late resorptions.) Early and Late Resorptions. (A conceptus is defined as a late resorption if it is grossly evident that organogenesis has occurred; if this is not the case, the conceptus is defined as an early resorption.) Fetal Observations: To minimize bias, fetal observations will be conducted without knowledge of dosage group. Fetuses will be examined for sex and for gross external alterations. Late resorptions and dead fetuses will be examined for gross external alterations to the extent possible. The body weight of each fetus will be recorded. Only body weights of live fetuses will be used to determine litter fetal body weight averages. Fetuses with gross external alterations will be fixed in Bouin's solution; all other fetuses will be discarded. Representative photographs of fetal gross external alterations will be taken. METHOD OF SACRIFICE: Rats will be sacrificed by carbon dioxide asphyxiation. Live fetuses will be sacrificed by an intraperitoneal injection of BeuthanasiaB-D Special, manufactured by ScheringPlough Animal Health. NECROPSY: Gross lesions will be retained in neutral buffered 10% formalin for possible future evaluation. Unless specifically cited below, all other tissues will be discarded. Scheduled Sacrifice: On day 21 of presumed gestation, female rats will be Caesarean-sectioned, and a gross necropsy of the thoracic, abdominal and pelvic viscera will be performed. The gravid uterus will be excised and weighed. Uteri of apparently nonpregnant rats will be examined while being pressed between glass plates to confirm the absence of implantation sites. Rats Found Dead or Moribund: 418-023P:PAGE 52 Protocol 418-023P Page 12 Rats that die or are sacrificed because of moribund condition, abortion or premature delivery will be examined for the cause of death or moribund condition on the day the observation is made. The rats will be examined for gross lesions. Pregnancy status and uterine contents of female rats will be recorded. Gravid uterine weights will not be recorded if precluded by autolysis. Aborted fetuses, delivered pups and/or concepti in uteri will be examined to the extent possible, using the methods described above. Uteri of apparently nonpregnant rats will be examined while being pressed between glass plates to confirm the absence of implantation sites. STATISTICAL EVALUATION: Averages and percentages will be calculated. Litter values will be used where appropriate. Additional procedures and/or analyses may be performed if deemed appropriate. DATA ACQUISITION, VERIFICATION AND STORAGE: Data generated during the course of this study will be recorded either by hand or using the Primedica Argus Automated Data Collection and Management System and the Vivarium Temperatureand Relative Humidity Monitoring System. All data will be tabulated, summarized and/or statistically analyzed using the Primedica Argus Automated Data Collection and Management System, the Vivarium Temperatureand Relative Humidity Monitoring System, Microsoft Excel [part of Microsoft Off ice 97 (version SR-2)]and/or The SAS System (version 6.12).

Carefully mark each beaker at the meniscus. This mark will be used during the preparation to bring the test substance slurry up to volume. C. Dosage Suspension Preparation: 1. Weigh the required amount of test substance on a piece of weigh paper or into an appropriately sized mortar (see PREPARATION CALCULATIONS). 2. If weigh paper is used, transfer the test substance to an appropriately sized mortar. Ifnecessary, grind the test substance into a fine powder. Slowly add a small amount of vehicle and grind. Continue to add vehicle slowly and grind the vehicle and the test substance together to form a fine slurry. Transfer the vehicle/test substance slurry to a marked beaker. 3. Rinse the mortar and pestle with additional vehicle to remove any remaining test substance. Transfer rinse to beaker. 4. Add additional vehicle to the beaker to bring volume up to the mark. Place on magnetic stir plate and agitate prior to and during administration and/or sampling. 5. Repeat steps (1) through (4) for each concentration. ate: 2 - 2 - M - ~ d Clarification: J NO -Yes [see attached clarification form] 4 18-023P:PAGE 69 ~ ~ ~ e s e u c h -. k 905 Sbeetr). ;tkivc, Haphmr,PA 19044 TclepbDnc: (215) 443-8710 Tclefix: (U5)443-8587 PROTOCOL 418-023P ORAL (QAVAGE) DOSAGEZbWGE D W E L O P m U XHIClTY STUDY OF POTASSIUM PERFLUOROBVTANE -ONATE (PFBS) XN RATS SPONSORSSTUDY NUMB= T-7485.11 Ammrtment 1 - 26 Fcbroary 2001 Any revisions made to'this finalized amendment must be made by subsequent amendment. 418-023P:PAGE 70 ATTACHMENT 2 ANALYTICAL REPORT 418-023P:PAGE 71 ANALYSIS OF DOSING SOLUTIONS USED AT ARGUS RESEARCH LABORATORY FOR SPONSOR'S STUDY NUMBERS T-7485.11, T-7485.12, AND T-7485.13 (ARGUS RESEARCH LABORATORY PROTOCOL NUMBERS: 418-023P, 418-023 AND 418-021) STUDY ID: A343.1 SPONSOR STUDY NOS.

All dose formulations were found to be within _+ 10% of the reported concentration except for four samples, 100 m g / d dated 1/11/01, 100 m g / d dated 2/23/01, 100m g / d date 9/4/01 and 200 mg/mL dated 1/11/01. These three samples were found to have measured concentrations of 88.9 %, 86.3 %, 76.6% and 76.8 % of target values, respectively. KEY PERSONNEL Raymond G.

OBJECTIVE The objective of this study was to determine the dose concentration of PFBS in the supplied dosing solutions received from the sponsor. 2. SAFETY All necessary procedures to ensure safety of the analysts were based on information contained in the Material Safety and Data Sheets (MSDS), provided by the producer of the test article and the study director. 3. Compliance The study described in this final report was conducted in accordance with the EPA Good LaboratoryPractice Regulations (40 CFR Part 160 and 792), OECD Principles of Good Laboratory Practice [C(97)186/FinalJ. For studies 418-023 and 418-023P Good Laboratory Practice Standards (1984) for W F 59 Nohsan No. 3850 were met. The final report accurately reflects the raw data obtained during the performance of the study. There were no adverse circumstancesthat affected the quality or integrity of the study. 4. EXPERIMENTAL 4.1 Analytical Procedures The sample preparation and analysis procedures as described in the analytical method BACG 3533 were employed for all analyses. Each sample was allowed to warm to room temperature and was then vortexed well before being sampled. An aliquot was taken from each and diluted as described in the method. (Note: the 66.7 rng/rnL and higher concentrated samples often were suspensions and the entire sample volume in some cases were diluted to the target range). Multiple calibration curves were prepared over a concentration range of 500 to 10,000 ng/mL and analyzed along with the samples as described in the method. The correlation coefficient for each curve was greater than 0.9982. 4.2 Results The results of the analysis are presented in the Tables I-III corresponding to the sponsors study number at the end of the report. 418-023P:PAGE 75 5.0 Conclusion A total of 30 dose formulation samples ranging in concentration fiom 3 to 200 mg/mL were analyzed by BACG 3533. All samples except for four, 100 mg/mL dated 1/11/01, 100 mg/mL dated 2/23/01, 100 mg/mL dated 9/4/01 and 200 mg/mL dated 1111 were found to be within k 10 % of the reported concentration.
