Martin, Governor R. Paul Wilms S. Thomas Rhodes, Secretary Director November 30, 1988 MEMORANDUM TO: Larry Coble \ THRU: David Vogt jail (J Trevor Clements X- Steve Tedde FROM: Jackie Nowell,( SUBJECT: Instream Assessment for Town of Jefferson WWTP NPDES Permit No. NC0021709 Ashe County JOC Case No. 88-08 Summary The Technical Support Unit has received a second JOC request for the Town of Jefferson to increase the flow of its WWTP by an additional 114,000 GPD. This increase in wasteflow is for accommodating the domestic sewage from proposed dischargers requesting connection to the Jefferson facility. Included are a sixty home retirement village and a golf course development with 250 homes and 130 condominiums. Jefferson requested their first TOC. in October, 1986 for an additional wasteflow of 75,550 GPD. The Winston-Salem Regional Office reports that 30,000 GPD of this flow has been permitted but is not yet entering the sys- tem. Several projects that had anticipated startups have not been con- structed. The current JOC expires August 1, 1989. Jefferson recently completed the expansion of their facility to 0.300 MGD. The WSRO reports that the Town of Jefferson wants to continue to dis- charge at their current JOC limits of 60 mg/1 of BOD5 and 50 mg/1 of TSS as a precautionary measure until they are certain that the expanded facility is operating properly and can meet final limits. Pollulivit Prcrcnlion Pays P.O Box 27687, Raleigh, North Carolina 27611-7687 Telephone 919-733-7015 An Equal Opportunity Affirmative Action Employer The impact of Jefferson's wasteflow on dissolved oxygen (DO) levels in Naked Creek was evaluated using Technical Support's Level B modeling frame- work. The results of the analysis indicate that the requested wasteflow increase of 114,000 GPD will have an unacceptable impact on the stream (per EEC criteria) by increasing the DO minimum by more than 0.5 mg/1. Our ana- lysis determined that the facility can only accept an additional 64,000 GPD under the requested JOC. In addition, because of the industrial influent to the Jefferson WWTP, we recommend that the facility perform monthly chronic toxicity monitoring of its effluent; we also recommend effluent monitoring for nickel. Analysis and Discussion The Town of Jefferson discharges into Naked Creek which is located in the New River Basin. U.S.G.S. flow data obtained in July, 1986 indicate that the summer 7Q10 flow at the discharge point is 2.8 cfs, with a drainage area of 6.4 square miles and an average flow of 12 cfs. This section of Naked Creek has a stream classification of C and is approximately two miles upstream of its confluence with the South Fork New River. As previously stated, the Jefferson facility has recently completed an expansion and the new design capacity is 0.300 MGD. Jefferson requested their initial JOC in October, 1986 and the pre-JOC flow was 0.1065 MGD (average flow 9/85-8/86). The requested JOC flow was 0.07555 MGD. The Post-JOC flow was 0.18205 MGD with recommended JOC limits of 60 mg/1 of BOD5 and 50 mg/1 of TSS. For this instream assessment, the post-JOC flow was calculated by adding the 1986 JOC flows (0.1065 MGD + 0.07555 MGD) to the 1988 JOC request of 0.114 MGD for a post-JOC flow of 0.29605 MGD. A review of compliance data from October, 1987 to September, 1988 reveal that Jefferson has been in compliance with the assigned JOC lim- its. The maximum values for BOD5 and TSS were 44.4 mg/1 and 54 mg/1, respectively. A Level B model analysis was used to assess the impact of the Jefferson discharge on dissolved oxygen in Naked Creek. Two models were run, one at 0.1065 MGD (1986 pre-JOC flow), and the other at 0.29605 MGD (post-JOC flow). The waste input for CBOD reflected the Winston-Salem Regional Office's recommended BOD5 limit of 60 mg/1; this yields a CBOD input of 120 mg/1 (using a CBOD/BOD5 multiplier of 2 for >10% industrial waste). Because of Jefferson's significant contribution of ammonia to Naked Creek, a waste input for NBOD was determined by using the average of the 1988 summertime NH3-N values (7.98 mg/1). This yields a NBOD input of 35.91 mg/1 (using a NBOD/BOD5 multiplier of 4.5). The model results at 0.1065 MGD predict the DO minimum of 7.29 mg/1 to occur at the outfall. Model results at 0.29605 MGD predict a DO minimum of 6.63 mg/1. This is a difference of 0.66 mg/1 and demonstrates an unaccept- able depression of the instream DO level per EMC criteria. Our evaluation determined that the maximum amount of wasteflow that the Jefferson WWTP can accept is 0.24605 MGD. At this wasteflow the model predicts a DO minimum of 6.79 mg/1, a difference of 0.5 mg/1 from the pre-JOC flow run (0.1065 MGD), thus meeting the standard 67(b) criteria. Based on the model results, we recommend denial of the JOC request for 0.114 MGD. However, Technical Support will recommend approval of 0.064 MGD additional wasteflow for the Jefferson WWTP. This is a difference of 0.050 MGD from the requested JOC flow. All model results are presented in Table 1. In addition, Technical Support recommends that this facility perform monthly chronic toxicity monitoring under the JOC. It is also recommended that the facility perform effluent monitoring for nickel during the same period. cc: Chuck Wakild Ken Eagleson Kevin Bowden Steve Reid Central Files WLA Files TABLE 1.

The Town is currently in violation of BOD and TSS final effluent limitations. Jefferson's WWTP is currently discharging an average of 0.1065 mgd, with a permitted flow of 0.15 mgd. A level B model has been run to assess the impact of the additional flow on the receiving stream. A discussion of the impact of the additional flow on the instream toxicity is also presented. Major Level B model inputs are presented below: Source 0w (mgd) current 0.1065 Average 6/86-8/86 with additional 0.18205 SOC request BODE (mg/I) 60 SOC limit NHa-NH,-N (mg/I) 12 Average 6/86-8/86 7010 (cfs) 2.8 The predicted D.O. sag occurs at the outfall. At the current waste - flow, the D.O. minimum is 7.65 mg/I. With the SOC flow, the D.O. minimum is 7.36 mg/1 (0.29 mg/I additional impact). Of primary concern in considering the additional flow is the effect on the instream waste concentration (IWC) and the potential for an increase in the instream toxicity. A comparison of toxicity testing results and the IWC at current and SOC discharge levels illustrates this concern: Source Teat LC60 Tech Services Self 4 Daphnia Static Fathead Minnow flow through Ceriodaphnia life cycle 8.2-55% 6.76% 3.6% 2 Daphnia 13.6%, none IWC Design Current SOC 7.65% 5.6% 9.14% Acute instream toxicity would therefore likely be occurring at 7010 streamflow conditions. The effect of increasing the wasteflow would be to increase the IWC. However, it is not known how the additional wasteflow will affect the effluent toxicity. While the diluting effect of the addi- tional domestic wastewater could conceivably be anticipated to reduce the effluent toxicity (LC50), it could also be anticipated that additional hydraulic loading would result in a lower level of removal of toxic consti- tuents because of the decreased hydraulic retention time, and an increased probability of upsets and/or short circuiting. In view of the current acute effluent (and instream) toxicity, it is recommended that serious consideration be given to SOC issuance until the subject facility can demonstrate achievement of toxicity goals.

Chemistry Sampling Locations: 01 - Naked Creek t N.C. 88/16-upstream of Jefferson WWTP-dilution water source 02 - Jefferson WWTP effluent taken from basin just prior to chlorination 02A - Jefferson WWTP influent taken from aeration basin influent weir 03 - Naked Creek t SR-1585-downstream of Jefferson WWTP Initial Comments and Conclusions: The Jefferson WWTP effluent resulted in a 96 hour fathead minnow LCso of 6.76%. The cladoceran Ceriodeohnie displayed a comparable LCso of 3.6% while a 48 hour Daphnia pulex static bioassay resulted in an LCso of 55%. The difference in toxicity observed in this last bioassay as compared with the toxicity dis- played by the Ceriodaphnia life cycle and fathead minnow flow -through bioassays most likely can be attributed to the difference in length of sampling times for the bioassays (96 hrs and 116 hrs for the fathead and Ceriodaphnia collections respectively, as opposed to 24 hrs for the Daphnia pulex bioassay) and the increased toxicity generally observed in bioassays as exposure times increase. Given the above toxicity results and the facility's instream waste concentration of 8.83% during low stream flow conditions, the effluent would be expected to cause significant acute toxicity in the receiving stream. Of the three indus- trial contributors tested, it would appear that Gates Rubber contributes the greatest and most consistent toxicity to Daphnia pulex, with Ashe Memorial Hospi- tal and Hanes Knitting each showing some acute toxicity in at least one test. Analysis of macroinvertebrate samples collected from Naked Creek above and below Jefferson WWTP indicates a reduction in taxa richness of the more sensitive intolerant insect orders. Mayfly, Stonefly and Caddisfly taxa totaled 31 upstream and 6 downstream. Reduction in taxa richness of these orders indicates a decline in water quality below the plant discharge. There are no chemical analyses results available at this time. These will be disseminated as they become available.
