AR226-2541 RESPONSE TO INFORMATION REQUESTED REGARDING APRIL 1992 VI REPORT (REFERENCE; EPA REGION III LETTER DATED MAT 5, 1997) DUPONT WASHINGTON WORKS WVD045875291 Responses to information requested in the referenced EPA letter are presented below. The response is organized in a series of 11 items which reference information requested in the EPA letter. Attachments are included at the end of this section. Item 1. "Please provide three copies of the plate locating the actual sampling points on the topographic map used in the Verification Investigation Plan, Page 4*. Response; Three copies of Map 599 (which is equivalent to 599A) are included in Attachment 1. Actual sampling points and their corresponding labels are shown on Map 599. Item 2. "Please provide known toxicological information" on C-8 and Triton X-100 constituents. Response: Some toxicological information on C-8 was provided in material safety data sheets (MSDS) information included in the April 1992 VI Report. Additional C-8 toxicological information is included 'in Attachment 2. ' ) > Triton X-100 is manufactured by Union Carbide Chemicals and Plastics Company, Inc. We are not aware of any toxicological studies or study programs conducted by DuPont on Triton* X-100, Our source of health and safety information on this material is the MSDS provided by the manufacturer. A copy of this MSDS was included in the April 1992 VI Report. Item 3. Provide results for chromium and m-Cresol on soil samples taken at the Polyacetal Waste Incinerator. Response: m-Cresol results for the two soil samples taken at the Polyacetal Waste Incinerator were both determined to be < 0.170 mg/kg. A revised copy of Table 3, page 54 adding m-Cresol results is included in Attachment 3. We have been unable to locate chromium results for the two soil samples and believe the analysis was not performed. 013027-3 AC003I82 EID078087 Item 4, JI?f*e1Prov5de the Local landfill closure information and the iSElSndSentCs?!-"* re8aFllln!' e' " "TM f the sur-faee .

Item 5. Please submit a report on progress to date for use of electrochemical techniques for in-situ stabilization of C-8 contaminated soils. Response: A" evaluation of electrochemical techniques for in-situ stabilization of soil containing C-8 was completed in late 1993. This evaluation concluded that C-8 stabilization using electrokinetics was not practical and a final report was not generated due to project termination. DuPont is not planning to perform any additional research and development to further evaluate this technology. Item 6, From VI Report Section 2.2,1: "Please confirm that the two spring samples taken at the Riverbank landfill were collected Plan)1*6 tWex1stlng 1eachate 5eePS (as specified in the Work Response: Yes. The samples mentioned were taken from the locations specified on Map 599, designated as RBlll and RBLL2, AC003183 013027-4 EID078088 Item 7. From VI Report Section 2.2.1: Explain why samples collected at the Riverbank Landfill and Anaerobic Digestion Ponds were not analyzed for butyraldhyde, adipic acid, hexamethyl diamine, PTFE, and chlorides. Response: In the cover letter of an updated QA/QC Plan submittal dated July 25, 1991, it was stated that adequate methods for determining concentrations of butyraldhyde, adipic acid, hexamethyl diamine and PTFE were not available and the compounds were withdrawn from the Work Plan. Chloride results are reported in Table 3 of the VI Report. Item 8. From VI Report Section 2.2.1: "According to the VI Work Plan dated December 14, 1990, the soil and groundwater samples collected from these borings were to be analyzed for zinc, C-8, Triton and PTFE only. If analysis was performed for additional constituents, the facility should indicate that activity in this section and summarize any significant results within the report." Response: The parameter list is generally described in the text in Section 2.2.1 of the VI Report and more specifically described in Table 1. Results are reported in Table 3. Data results are discussed in VI Report Sections 7.0 through 10.0. Conclusions and Recommendations are presented in VI Report Section 11.0. Item 9. Response: From VI Report Section 8.3: "The facility should explain why the Riverbank Landfill samples were not analyzed for the following constituents as specified by the Work Plan: butyraldhyde, adipic acid, hexamethyl diamine and PTFE." Please see the response to Item 7, Item 10 From VI Report Section 9.2: "...the Facility should submit further information on hydraulic flow patterns between RBLL1 and RBLL2 so the potential for migration of contamination can be determined." . Response: The hydraulic flow patterns between Riverbank Landfill seeps RBLL1 and RBLL2 are conceptually displayed on VI Report Figures 5 and 10, Both figures show that any groundwater present in the Riverbank Landfill would be perched above the riverbank "slumped clay unit, and would likely flow toward the Ohio River. These two areas do not appear to be interconnected. RBLL1 flow is effectively captured by the pump and treat system which features a french drain keyed into the clay unit. Item 11. From VI Report Section 10.5: Revise Table 3 to include analytical results for total chromium and m-cresol.

Precautionary Information PC-143 was fed to albino rats for 2 years; no compound induced carcinogenicity was found in the study. There were statistically significant compound related benign testicular tumors, # Groups o f 120 male and 120 female rats were fed diets containing either 30 or 300 ppm o f FC-143 for up to 2 years, while a control group received only untreated feed. The average daily dose o f FC-143 for both sexes was 1.5 or 15 mg/kg/day for the 30 and 300 ppm groups, respectively. The incidence of tumors found in this study was relatively low and the types o f neoplasms round were not different from the tumor profiles commonly found in geriatric rats. Hepatocellular tumors were very slightly increased in the high-dose mate rats; however, not to the extent that would be expected considering the morphological evidence of chronic hepatocellular stimulation first seen at the one-year necropsy (3M , 1987b), All o f the liver tumors found in the above study were carcinomas and the incidence in the control, 30 ppm, and 300 ppm groups (males: 3/50. t/5 0 . 5/50; females: 0 /5 0 ,0 /5 0 .1 /5 0 ) did notjanjs v 10 to dosc mlated. The incidence o f nodular hyperplasia in the liver (males: 1 /50.0/50,2/50; 1 EID078093 AC0O3188 females: 0 /5 0 .0 /5 0 .3 /5 0 ) was also slightly increased, though not statistically significantly (DuPont, 1987). All o f the other remarkable tumor incidence values produced in this study were associated with endocrine or endocrine-sensitive organs. The incidence o f mammary gland fibroadenomas (10/50 (20%). 19/50 (38%), - i / 5 0 (42%)) suggested a compound-related effect. However, when compared to tlaskeli s historical control incidence for tius strain o f r t 4 ( 3 ? % U ^ to be any compound-related effect. The incidence of testicular Ley ig e&li adenomas (0/50 (0%). 3/50 (6%). 7/50 (14%)) was also suggestive ot a compound-related effect. When compared to Haskell'S control incidence tor this strain o f rat (6.1%. range 1-12%). the incidence in the 300 ppm group shows a taritrionllv significant increase (DuPont, 1987). III. Health Hazardous Data EYE CONTACT: FC-143 can be irritating to the eyes upon direct contact. Animal studies indicate FC-143 is moderately irritating to the eye. Airborne FC-143 may cause ey e injury consisting o f corneal injury. APFO (100 mg) was moderately irritating tojhQeyes of rabbits (mean score - 14.0; highest possible score * 110.0)* Iridial and conjunctival effects were evident in unwashed eyes, but only conjunctival effects appeared when eyes were washed after exposure (Griffith and Long, 1980). By day 7, 4/6 eyes were free o f irritation. The mean irritation score at that time was 2.0/110 (3M. 1976). Rats exposed to APFO during a four-hour jnjialatjsfl period exhibited cnn&ai opacity and ulceration which were still microscopically evident after 42 days (DuPont. I960). SIO N CONTACT: FC-143 may be absorbed through the skin. Slightly toxic when absorbed through the skin. FC-143 is non-irritating to the skin, . LD50 (male rats) = 6959 mg/kg (DuPont, l979d: Kennedy. 1985), m e rats dosed at 3000.5000 and 7500 mg/kg showed initial weight loss. Rats dosed at 5000 or 7500 mg/kg were lethargic on the day o f treatment and the majority had wet and/or stained perineal areas. Chromodacryorrhea. was seen in rats dosed at 7500 mg/kg (DuPont, 1979d; Kennedy, 1985). FC-143 was found to be non-irritating to the skin o f albino fafrfrilS. when No o ftested per conventional (Draize) procedures. signs dermal irritation were noted following a 24-hour contact period of the powder with intact and abraded skin test areas o f six animals (3M. 1976: Griffith and Long, 1980). `t i i r EID078094 AC003189 J Skin Absorption LD50: <TC7gj r a /kg U rabbits (DuPont, I979d; Kennedy, 1985).

Repeated inhalation exposure produced liver changes and elevated blood organofluoude levels ill rats. 4-hour LC5Q (rats) = 980 me/m! (Kennedy et a l. 1986). Mo deaths resulted from a one hour exposure to a a smifigl concentration o f FC-143 (18.6 mg/L). Clinical signs during exposure were ifiLnasfli Htehawe. yellow staining o f the a n o g enital far, drv rales, red mat.eri.4l armind the eve* livation. and lacnmaliflfl. Similar signs appeared post-exposure in a 14-day observation period. Biluteral mottling of the lungs was observed in eight o f ten autopsies (Griffith and Long. 1980; r,mnp< of rars were exoo fifd m hours a dav. five davsiit week for two, w^eks to 1 0 7.6 or 83.9 mg/m3 o f C-8. Observations o f clinical signs during exposure showed only slight nasal and ocular discharge. However, after three to four days on test at 83.9 mg/m3 one fat died during exposure and another wax sacrificed in txiremLt. Both o f these rats had lost a considerable amount of weight. Body weight o f the 1.0 mg/m3 groups were similar to those ol the controls while the body weights o f the 7.6 mg/m group were significantly higher. Organ to body weight ratios demonstrated a dose-related significant increase in lung, liver and testes weight immediately after exposure ended. The liver/body weight ratios were significantly higher in the 83.9 mg/m' group through a 28-day recovery period. Clinical laboratory measurements demonstrated an increase in serum alkaline phosphatase in all exposure groups after ten exposures, which persisted in the 83.9 mg/m group through 14 days of recovery. Pathological evaluation revealed heavy livers and microscopic lesions in the 7.6 and 83.9 mg/nv groups. These changes were reversible following a 28-day recovery period, mood fluoride analysis clearly demonstrated a dose-related presence.of C-8 in all groups, including the controls. The amount o f C -8 in blood decreased with time, but was detectable after 84 days recovery in both controls and the 83.9 mg/m' group (the initial blood level o f C-8 in the 83.9 mg/m3 group was 108 pjsm falling to 0.84 ppm after 84 days with a half-life o f 5-7 days; in the l m g/m group an organoflueride level o f 13 ppm was detected immediately after the last exposure (DuPont, 1981b; Kennedy eta l., 1986).

FC-143 i. .......... ^ See orecautions for results of 2 year study. . LD50 (rats) = S40m g/ka (3M, 1978c; Griffith and Long. 1980; U beletal., 1980). Rats receiving intragastric doses as low as 60-90 mg/kg had enlarged livers (DuPont 1968b). fi^ i^ in testin al irritation was also observed m ruts infesting APPO (DuPont, L968b, 1969), Administration o f ten successive doses o f 6.7 mg/kg to six rats caused moderate enlargement o f the liver and light eniarg&nent oftarfneylgad, testes. Simultaneously there was a sMiMit e ^ I or^P4ntTe4tic.we)H Dt and the lungs o f rats showed slightly enhanced pneumonitis (DuPont, 1961b). Groups of rats and mice were fed 0-30,(XX) ppm FC-143 daily for 28 days. At 10,000 and 30,000 ppm all the rats died within the first week. In general, rats showed decreased body weight and an increased liver weight (at > 30 ppm, males and > 300 ppm. females). Treatment-related histopathologic changes appeared in ail test groups. In mice, aii the m ice dosed at 1000 ppm died within the first two weeks. AU the mice administered 300 ppm, except one male, died within 26 days o f testing. One mouse died in each o f the 30 and 100 ppm test groups. No other deaths occurred At doses o f 3000 ppm a rough hair coat and muscular weakness were evident in mice. Slight cyanosis, decreased body w eigh t. gain and increased average liver weight were also noted (Griffith and Long, 1980). IV . D evelopm ental Toxicology . FC-143 is not teratogenic in rats, * Groups o f pregnant rats were administered 0 .0 5 ,1 .5 ,5 0 or 150 mg/kg o f FC-143 on days 6-15 o f gestation. Abnormal clinical signs were observed and deaths occurred only in the high-dose group. 7 hree rats in the high dose group died. All three o f the rats that died were ataxic and two o f the rats were pale for one or two days before death. The surviving high-dosc rats did not have abnormal clinical signs and signs o f toxicity did not occur in lower-dose animals. F C -143 was not em b r n t e d s and did not affect the ovaries or reproductive tract contents o f the dams. The mean number o f male, female, total, and dead fetuses, the mean number o f resorption sites, implantation sites, corpora lotca, and mean fetus w eights I61EOODV 4 ii EIDQ78Q96 of the four PC- 143 dusse groups were not significantly different from the controi. FC-143 didjflpf cause comnound-retated abnormal gross ML. f i n d e r , HiHF r- m pf0ducu Fetal talciH malformations. A significant higher incidence o f the skeletal finding o f one stemabrac missing occurred in the high-dose group. One stemabrae missing Is a ^ minor skeletal aberration and was not considered a malformation in this study. Further, the incidence o f the finding was not different among the control group and the lower three treatment groups. The incidences o f skeletal findings associated with delayed ossification and rib aberrations were not different among the treatment groups and controls Fetal lens findings were observed to occur in individual fetuses o f all dose groups including the control group. The lens findings were localized to the area o f the embryonal nucleus, although a variety o f morphological appearances were present within the location. The range o f morphological appearances as observed under the dissecting microscope included*, discoloration o f the lens near the anteriocentral region extending from beneath the lens epithelium to half-way through the lens posteriorly, a cleft at the anteriocentral lens region or a combination o f lens discoloration and the presence o f a deft. The lens findings observed under the dissecting microscope were interpreted histopathologically as a freehand sectioning artifact o f a normal area o f primary lens fiber degeneration. The cleft was a space opened up at the vestige o f the tens vesicle remnant and consisted o f a separation o f primary lens fibers o f the embryonal nucleus from the lens epithelial cells. The dark streak discoloration o f the embryonal nucleus resulted from either the tens being freehand sectioned across the area of norma! primary lens fiber degeneration or an artifact being created in the tens during freehand sectioning accentuating the area o f normal primary lens fiber degeneration. The differences in the appearance o f the tens artifact in individual fetuses and even among dose groups were largely due to the manner and frequency in which the artifact was created and the limitations inherent in visualizing the artifact under the dissecting microscope.. Histologically, the tens artifact was the same in all dose groups regardless o f the morphological appearance described under the dissecting microscope. FC-143 in uter exposed fetuses did not have compound-related changes in their lenses (3M, 1981b). FC -143 is not teratogenic in rabbits, # Groups o f pregnant rabbits were administered 1 .5 ,5 or 50 mg/kg o f FC-143 in distilled water on days 6-18 o f gestation. At 50 mg/kg the dams lost more weight than the untreated controls. FC-143 was not embrvotoxic nor teratogenic (3M, 1982b). Statistically significant increases in the incidence o f 13 ribs in the high-dose group and 13 ribs spurred in the mid dose group were observed. W hile these findings arc significantly greater in the dosed rabbits than in the controls, they are not considered AC003I92 5 EID78097 teratogenicchtmgormnlhrmtttiona. T h ^ ' stress-related changes indirectly related to FC-143 administration (3M, 1996c). . V .

I978d). V L O ccupational Exposures A study o f occupationally exposed workers at a plant which produces C -8 showed organic fluorine levels in the blood ranging from 1 to 7 ! PP" * One worker with a level o f 70 ppm was removed from the fluorochemica! production area and his Wood analysed for organic months. After 18 months, his organic fluorine level had decreased to 39 ppm (45% reduction) (libel et ai-, 1980). ACO03193 6 1ID 078098 INFERENCES 1. DuPont Co., Haskell Laboratory Data; 1961b.
