DEPARTMENT -OF NATURAL RESOURCES NPDES PERMITTING SUBJECT: Notification of production increases from Nafion® HFPO facilities involving NPDES Permit NC 0003573 for Fayetteville Works of E.I. Du Pont. Background In 1976, di-scussions were held with the N.C. regulatory authorities concerning a new fluorocarbon manufacturing facility to be added to the Fayetteville Works of E.I Du Pont located on Route 87 in Bladen County at the Cumberland County line. The outfall from Fayetteville Works discharges into the Cape Fear River just below the Corp of Engineers Lock No.3. Subsequently, modified NPDES Permit NC0003573 was issued on 10/13/77 to cover this disclosure. The principal chemical operation involved in the Nafion® Area is the oxidation of hexafluoropropylene (HFP) to form the hexafluoropropylene epoxide (HFPO) which is an intermediate for manufacture of other fluorocarbon chemicals at this site and other Du Pont sites. The demand on this intermediate principally at other Du Pont sites now requires a 4.0 expansion of the facility. Fortunately, much of the major operating equipment including the facility Waste Gas Scrubber was significantly overdesigned for the original capacity and major production increases can be obtai-ned with relatively modest changes - such as column packing, and larger pumps condensers and instruments - rather than major changes such as larger vessels and building expansion. Current Submission Management Requirements, Part II -A-1, of the NPDES permit dictate notification of production increases which will increase the level of two existing pollutants, fluoride and trifluoroacetate, currently not limited in the existing permit. A review of the last permit application and subsequent permit indicate that neither relief from any of the current permit discharge limitations nor changes to the application information regarding the flows from -the Nafion® Manufacturing operation are needed. BETTER THINGS FOR BETTER LIVING ' T N.C. DEPARTMENT OF NATURAL RESOURCES PAGE 2 The increases in the two non—limited pollutants to the outfall are shown in attachment 1. Toxicity testing shows that concentrations are not acutely toxic to representative aquatic life even at the concentration of our undiluted outfall. These toxicological data are presented in Attachment 2 (previously submitted to Mr. Wilms on 3/7/85 in conjunction with the 1985 permit renewal). The maximum concentration tested were 1.6 times the outfall fluoride concentration and 2.5 times the outfall trifluoroacetate concentration. After mixing with the 7Q10 minimum, the maximum fluoride would only be 10% of the drinking water standard. As an additional "housekeeping" item concerning the permit, the "Supplement to Permit Cover Sheet" page, Item 1, should indicate a 111_1 mgd wastewater treatment facility ... and two clarifiers" not "a 0.5 mgd" and "a clarifier".

There was 2096 mortality in the 100% waste concentration and 0% mortality in the 7590 concentration. Objective; To determine the. acute toxicity of the test mzterial to a macroinvertebrate Daphnis magna. Procedure-. The test material, as received was diluted with laboratory mass •culture well water to yield thb desired exposure concentrations. After mixing, 200 ml: aliquots of each concentration were introduced into each of two separate 250 mL glass exposure vessels. Two identical vessels containing only laboratory mass culture water were designated as controls. Stability of the test material in water was not determined because it is not a critical Factor in static acute aquatic tests. Ton Haskell bred daphnids (Daphnia magna) less than 24 hours old were randomly assigned to each vessel. Haskell bred daphnids Daphnia magna are identified by labeling the culture and test vessels. food was not provided during the test, Test solutions were not aerated and t•emperut'ure was maintained between 19.6 and 20.0°C. Photoperiod was maintained at 16 hours light:8 Hours dark. Immobility counts and observations were made at 24 and 413 hours after the exposure was initiated. Dissolved oxygen and pH were measured in the controls, low, medium, and high exposure solutions at the beginning, and after 24 hours, and 48 hours of exposure. The total" alkalinity, hardness (EDTA), and conductivity of the controls, low, medium, and' high exposure solutions wero measured•at-the beginning of -the exposure.

Unchlorinated mix wastewater was not acutely toxic to bluegill sunfish under static, unaerated test conditions during a 96 -hour exposure period. Objective: To detexmine tip acute toxicity of the test material to a warm freshwater fish. Procedure: The test material, in original form, was introduced into commercial, glass, rectangular 5 1/2 -gallon aquaria and diluted with laboratory well water to yield the desired exposure concentrations in 15 ifter" final voluues. An identical vessel containing only laboratory well water was desiUnatod as the control. Stability of the test material in water was not determined because it is not a critical factor in static acute aquatic tests. Ten juvenile, unsexed bluegill sunfish (Lepomis macrochirus) fron Sea Plantation Inc., Salem, Massachusetts with a 4.1 cm mean standard length (range 3.3 to 4.5 cm) and 1.25 g mean wet weight (range 0.57 to 1.64 g) were randomly assigned to each test vessel. The fish were in our laboratory for 12 days before being used for this test. Bluegill sunfish are identified by labeling the culture and test vessels. Fish were not• fed for 48 fours prior to or during the exposure. The test- solutions were riot- aerated and temperature was maintained at 22°C. Photoperiod was maintained at 16 hours light: 8 hours dark. Mortality counts and observations were made every 24 hours during the 96 -hour exposure period. Dissolved*'Oxygen was measured in the control, low, mediun, and high test concentrations at the beginning of the test and at 24-hour intervals during the 96 -hour exposure period. The pH was measured in the control, low, medium, and high test concentrations at the beginning of the' test and at 24-hour intervals during the 96 -hour exposure period. 'total alkalinity, hardness (:DTA), and conductivity were measured at the beginning of the test in the control, low, medium, and high test concentrations. -All rsrords from this test will be maintained at Baske].1 laboratory Lor '2=icology and Industrial Medicine or at the Du Font Hail of Tacords. Results: Test razijlts fnr bluegill sunfish are presented in Table 1, Unchlorinated mix wastewater was not acutely toxic to bluegill sunfish under static, unaerated test conditions during a 96 -hour exposure period. - The chemical and physical parameters measured during the test-, reported in Fable II, were all within acceptable ranges. * S non s Dnchlorinated mix wastewater ** L,C50 = The concentration which is lethal to 50% of a test population during the specified time period. - 2 - Report by: �CGIJ(� .� �C> /�C•• / Charles L.
