Mangles Ir THROUGH: Tom Stockton/ \\'� / Trevor Clement., SUBJECT: Instream Assessment for Eden -Mebane Bridge WWTP NPDES Permit No. NC0025072 and Eden -Dry Creek WWTP NPDES Permit No. NC0025151 Rockingham County KiRfu�L3i ili4iftiIII9 The Technical Support Branch has received an instream assessment request for a Special Order by Consent (SOC) for Eden -Mebane Bridge WWTP to allow flows up to 9.0 MGD from 7.0 MGD (design capacity). The requested additional flow is due to current infiltration problems which have placed the subject facility in noncom- pliance with the flow limitation contained in the NPDES permit, and also, to accept additional industrial flow until the existing WWTP is expanded. This facility has a flow average (09-88/08-90) of 6.51 MGD, with a maximum monthly flow average of 8.66 MGD which occurred in March. The City of Eden has also requested an SOC for Eden -Dry Creek WWTP to increase the permitted flow from 0.5 MGD (design capacity) to 1.0 MGD. The requested additional flow is due to current infiltration problems which have placed the subject facility in noncompliance with the flow limitation contained in the NPDES permit. Furthermore, the City would like to divert flow from the Eden -Mebane Bridge WWTP to this facility until the Eden -Mebane Bridge WWTP is expanded. Eden -Dry Creek WWTP has an average flow (09-88/08-90) of 0.445 MGD, with a maximum monthly flow average of 0.59 MGD which occurred in June. The City of Eden has also applied for a permit modification to expand the Eden -Mebane Bridge WWTP. The requested flow is 9.0 MGD and ultimately 13.5 MGD. The application has been returned until an environmental assessment (EA) for this expansion is provided, as per current regulations. A scoping session for the preparation of an EA was held in DEM's Central Office on December 11, 1989. It is our understanding that the City of Eden has expeditiously initiated the preparation of the EA. The results of a level B water quality modeling analysis indicate that the requested flow increase will have very little additional impact on the dissolved oxygen concentration within the receiving surface waters. Therefore, under EMC criteria, there is no basis for denying a 2.4934 MGD flow increase for Eden -Mebane Bridge WWTP and a 0.555 MGD flow increase for Eden -Dry Creek WWTP. However, the Technical Support Branch is also concerned about the toxicity potential of the industrial component of the wastewater. A chronic ceriodaphnia toxicity test performed by DEM on January 22, 1987 does not indicate that toxicity problems would be expected as a result of the Eden -Mebane Bridge WWTP discharge. However, since neither facility is currently required to perform toxicity tests, there is no updated information available to assess any current whole effluent toxicity _ problems at expanded flows. Contingent that no significant environmental impact is determined by the EA, the SOC's allowing additional allocation of domestic and/or industrial contrib- utors to the treatment works should be submitted to the EMC for approval. It -is recommended that the flow additions be granted in increments, according to a schedule for increasing flows from individual contributors (i.e. allocation of flow to*9.0 MGD and to 1.0 MGD to Eden -Mebane Bridge WWTP and Eden -Dry Creek WWTP respectively, should not be all granted at one time). This strategy will provide a short period of time to allow the Winston-Salem Regional Office to determine the potential toxicity impact (i.e. based on toxicity test results) of the initial industrial flow additions to each facility. Should no toxicity problems be documented, subsequent flow allocations could be granted under current standard procedures for flow additions via administrative letter. However, if toxicity is present, then the facility should be made to demonstrate that the additional industrial flows are treatable or the additions should be delayed until consistent compliance with the toxicity limits is achieved. Also, should an SOC be issued prior to approval of the EA, it should not allow additional sources of domestic and/or industrial waste to be served by either facility until a "Finding of No Significant Impact" (FONSI) has been issued by the Division. In this case, the SOC should only address the infiltration problems currently observed in both facili- ties. Finally, given that the additional source of wastewater is from textile industries, it is recommended that the order clearly address color. Upon renewal of their NPDES permit in early 1990, Eden will be required to control color in their effluent to a specified level. Therefore, the Order should contain mile- stones for establishing facility headworks analyses, modifying existing pretreat- ment permits, and attaining compliance by a specified date. The addition of the proposed industrial sources should not disrupt this process. Background Information Eden -Mebane Bridge WWTP discharges into the Dan River which is classified "C" waters. The Dan River is characterized at the discharge point by the following: DA = 1700 sq. miles; 7010 - 313.0 cfs and Qavg = 1620.0 cfs. On August 11, 1989 the Eden -Mebane Bridge WWTP was placed on a moratorium for failure to comply with the flow and TSS limitations as set forth in the permit. Eden -Dry Creek WWTP discharges, downstream from Eden -Mebane Bridge WWTP, into the Dan River. Stream classification at the point of discharge is also "C" waters. Hydrologic characteristics at the discharge point are as follows: DA = 1730 sq. miles; 7Q10 s 318.0 cfs and Qavg = 1644. 0 cfs. The Winston-Salem Regional Office has indicated that violations of the flow limitations, in both facilities, are mainly due to infiltration problems and because the Eden -Dry Creek facility is used as a "diversion" for excess flow from Eden -Mebane Bridge WWTP. Ivsis and Discussi The Eden -Mebane Bridge WWTP DMR's indicate that effluent flows above 7.0 MGD and high BOD5 concentrations occur during periods of heavy precipitation, precisely when the stream flow is above or at average condition providing a higher dilution for the effluent (i.e. lower IWC). Also, the self -monitoring reports indicate that, for the most part, this facility's effluent is well below the secondary limitations contained in the NPDES permit even during periods of hydraulic over- load. The self -monitoring data further indicates that the highest BOD5 monthly average recorded during the last year was 14.47 mg/l. However, a BOD5 daily maximum value of 136 mg/1 and a BOD5 weekly average of 60 mg/1 have been documented in the DMR's during periods the plant has been hydraulically overloaded, justifying a need for a BOD5 permit limit relaxation during the life of the Order. The Eden -Dry Creek WWTP DMR's indicate that effluent flows above 0.5 MGD occur during periods of heavy precipitation, precisely when the stream flow is above or at average -condition, providing a higher dilution for the effluent (i.e. lower IWC). Also, the self -monitoring reports indicate that, for the most part, this facility's effluent is well below the secondary limitations contained in the NPDES permit even during periods of hydraulic overload. The self -monitoring data further indicates that the highest BODS monthly average recorded during the last year was 19.0 mg/l. However, a BOD5 daily maximum value of 34 mg/1 has been documented in the DMR's during periods the plant has been hydraulically overloaded. Although Technical Support does not usually performs instream assessments for flow allocation above a WWTP design capacity, best professional judgement based on the above considerations resulted in the following technical analysis: Eden -Mebane Bridge WWTP A level B analysis was performed using a wasteflow of 6.5066 MGD and the suggested SOC limits of 40 mg/1 BOD5 and 10 mg/1 NH3-N. The DO concentration was assumed 0.0 mg/1 at the effluent. This model predicted that the instream DO sag (6.89 mg/1) occurs at milepoint 7.85. A second run was performed using the post-SOC flow of 9.0 MGD, with all other inputs constant. The results of the second model predicted the DO minimum (6.74 mg/1) to be also at milepoint 7.85. Eden -Dry Creek WWTP A level B analysis was performed using a wasteflow of 0.445 MGD. Technical Support does not recommend that the effluent limits be relaxed during the SOC interim period. Therefore, effluent concentrations of 30 mg/l BOD5 and 20 mg/1 NH3-N were used. This model predicted that the instream DO sag (6.77 mg/1) occurs at milepoint 7.85. A second run was performed using the post-SOC flow of 1.0 MGD, with all other inputs constant. The results of the second model predicted the DO minimum (6.74 mg/1) to be also at milepoint 7.85. Conclusion In accordance with EMC criteria for judging instream impacts, the model results demonstrate no significant depression of the instream DO level or extension of the zone of impact when the wasteflow is increased at both facilities. However, the additional flow is beyond the design capacity of existing treatment works at both facilities. Therefore, the additional flow will continue to overload the treatment works. Caution should be exercised by the Division in allocating additional sources of industrial flow by allotting flow incrementally and by close oversight of these source additions impacts on the ability of the facility to comply with their whole effluent toxicity limit. Also, allocation of the additional industrial flows should not impede Edenfs progress toward obtaining compliance with final effluent color limits. Accordingly, the Winston-Salem Regional Office should process the SOC contingent upon successful completion and approval of the pending EA.
