NPDES No. NC0024911 The recommendations made for the MSD of Buncombe County JOC were reexamined upon receipt of your memo dated May 1, 1989. We appreciate your suggestion that we use influent concentrations in our models for instream assessments when no ammonia limit exists and the efficiency of treatment is in question. This method will be considered in future situations when similar circumstances are present. When the maximum monthly average influent ammonia con- centration (approximately 9 mg/1) measured during the summer of 1988 by MSD is used, the increase in the BOD JOC limit is not expected to violate JOC criteria. Therefore, the proposed change in JOC limits (BOD, = 60 mg/1, TSS = 75 mg/1, Fecal Coliform = 10000/100 ml) can be processed. You were also concerned about the reaeration prediction meth- ods employed in the modeling analyses. Some of your concerns would have been alleviated if you had phoned me rather than writ- ing to the administration that the results were "less than sup- portable." The O'Connor -Dobbins reaeration formula probably pre- dicted reaeration fairly well. The formula was developed from streams 1 to 30 feet deep. It was based on streams which had lower velocity than that predicted for the French Broad River, but most of the reaeration formulas used in QUAL2E result in similar predictions for reaeration (see attached spreadsheet results). With regard to the Ecusta Study, the facility is located 50 miles upstream of the MSD outfall where the slope is higher. Therefore, one would expect the reaeration to be lower downstream of the Bun- combe County discharge than that determined in the Ecusta study. Please let me know if I can be of further assistance in this matter.

Haner, Environmental Chemist Water Quality Section / ARO VACA-e-tait Subject: Review of Instream Model Projections Proposed JOC Amendment (JOC #88-26 Ad) MSD of Buncombe County NPDES Permit No. NC0024911 The instream DO model prepared by Tech Services in consideration of the request from MSD of Buncombe County (NPDES Permit No. NC0024911) to amend its existing JOC properly evaluated current MSD flow conditions (26.6 MGD) as well as the maximum allowable flow under this Order (32.3 MGD). Ammonia projections based upon maximum daily compliance data at 13 mg/1 is a worst case concentration since this number represents a single weekly test result reported in the April 1988, monthly monitoring report. More importantly, however, is the influent data which should be used in the model projections to represent worst case conditions with the RBC system. Use of an effluent ammonia concentration of 20 mg/1 in model projections for this discharge is not supportable based on a review of influent self -monitoring data. Review of these influent data over the past 14 months (ending 2/89) show the highest ammonia reported by weekly analysis as 13.4 mg/1 (copies attached). A recent PAI conducted at this facility on 1/25/89 in conjunction with laboratory certification procedures lend credence to these results in that the PAI showed no deficiencies with MSD's ammonia procedure. Use of worst case conditions based upon influent ammonia data project no WQ problems for this proposed JOC amendment. Interchange Building, 59 Woodfin Place, Asheville, N.C. 28801 • Telephone 704-251-6208 An Fnue,al {l.•..,r,t., Kent Wiggins Memorandum May 1, 1989 Page Two Review of the instream DO projections raises questions as to the applicability of the O'Conner-Dobbin formula to this discharge in the French Broad River. My understanding is that this formula is basically used for deep water streams unlike the French Broad River; therefore, rendering these MSD projections less than supportable. While use of the Ecusta Study also would not be a perfect match to 7Q10 flow conditions in the French Broad, projections using this study would appear more realistic. Even using the O'Conner-Dobbins formula with a 13 mg/1 ammonia concentration at 32.3 MGD shows compliance with the dissolved oxygen water quality standard. Finally, both acute and chronic toxicity monitoring requirements are contained in Attachment A together with influme DO monitoring. These requirements are consistent with the draft NPDES Permit using the 3/89 WLA prepared as part of the permit process. Considering the above review and discussion, it is recommended that the interim Limits contained as Attachment A in the proposed JOC amendment remain unchanged and that the document be processed accordingly. Should you have additional questions, please advise. MLH Enclosure cc: Dennis Ramsey Trevor Clements DIVISION OF ENVIRONMENTAL MANAGEMENT April 25, 1989 MEMORANDUM TO: Forrest Westall Dennis Ramsey THROUGH: Randy Dodd `LUj Trevor Clements Ken Eagleson 1�- FROM: Ruth Clark IZCD '....- PAL SUBJECT: Proposed JOC Amendment (#88-26 Ad) Metropolitan Sewerage District of Buncombe Co. NPDES No. NC0024911 Background The Metropolitan Sewerage District (MSD) of Buncombe County has requested an amendment to its JOC to increase its BODS limit from 40 mg/1 to 60 mg/1, its TSS limit from 40 mg/1 to 75 mg/1, and its fecal coliform limit from 1000/100 ml to 10000/100 ml. The amendment is requested since it was necessary to remove portions of the activated sludge system to complete construction of the RBC/microscreen facility. Analysis and Discussion MSD discharges to the French Broad River, a class C stream. At the outfall the stream drains an area of 966 square miles and is characterized by an average flow of 2140 cfs and a 7Q10 flow of 466 cfs. Level B model runs were performed at the current monthly maximum flow (26.6 MGD) and at the JOC flow limit (32.3 MGD). Two sets of reaeration rates were input based on studies upstream by DEM (approximately 8/day) near Ecusta and calculations using the O'Connor -Dobbins formula (approximately 2/day). Effluent DO (2/mg/1) and ammonia (13 mg/1) concentrations were input based on compliance data. An effluent ammonia concentration of 20 mg/1 was also evaluated since it was unknown if the conversion to the RBC/microscreen would affect nitrification. A total of eight model runs were completed, and the results are given in Table 1. The results indicate that at critical conditions (7Q10 stream flow, JOC flow, low reaeration, and NH3 = 20 mg/1) the stream standard for dissolved oxygen may be violated. Further model runs indicated that a JOC limit of 5 mg/1 DO, 18 mg/1 NH3, or a flow limit of 30 MGD will protect the DO standard. Dilution calculations were performed to estimate the instream fecal coliform level. Upstream fecal coliform concentrations taken at ambient station E4280000 during flows less than 600 cfs since 1985 were averaged to obtain a background concentration. The analysis predicted an instream fecal coliform concentration of 1070/100 ml during 7Q10 conditions. Recommendations Since the DO stream standard may be violated during critical condi- tions, the JOC should contain instream monitoring requirements near the dissolved oxygen sag point (14 miles downstream). The monitoring point should be located at the first accessible point upstream of Ivy Creek. In addition, a JOC limit of 5 mg/1 DO, 18 mg/1 NH3, or 30 MGD of flow should protect the DO standard. The actual discharge point for the facility is a hydropower flume. Water quality impacts in the flume are currently unknown. Fisheries studies have documented fish populations in the flume. A wasteload allocation was completed in March, 1989 with an acute toxicity requirement and effluent and flume DO monitoring (attached). It is recommended that toxicity and DO (upstream and downstream in the flume) monitoring also be included in the JOC. Please advise if questions.

NC0024911 O��+0302. L fir, c�d i��v� The proposed JOC amendment (attached) for MSD of Bunccmbe County (NPDES Permit No NC0024911) was developed through review of those treatment. problems beginning to surface at the MSD wastewater treatment facility during the final stages of construction/conversion of the existing activated sludge system to the RBC/microscreen process. As you are aware, this facility is being expanded from 25 MGD to 40 MGD: Current JOC interim limits are monthly averages of 40 mg/1 for both BOD and TSS. The final completion and compliance dates.currently are March 1, 1990, and July 1, 1990, respectively. The amendment will change both the interim limits (BOD 60mg/1, TSS 75 mg/1, Fecal Coliform 10,000/100 ml) and the final completion/compliance date in the JOC; July 1, 1990, and October 1, 1990, respectively. In a meeting on March 22, 1989, MSD demonstrated that compliance with the existing interim JOC limits was not feasible due to treatment problems which resulted when it became necessary to take units specific for the activated sludge system out of service for replacement with the RBC/microscreen facility. These compliance problems were not anticipated to this degree when the initial JOC was developed. The February, 1989 DMR (attached) shows the compliance problems beginning on or about mid month when conversions away from the activated sludge system actually began. Adjustments have not been fully successful in remedying the problem. Compliance with the fecal coliform limits in the permit are also anticipated due to work on the disinfection system. Also, the contractor has experienced reasonable delays necessitating a four month extension of the compliance schedule. Even though additional flow for this facility under 67(b) guidelines is not being requested and a new flow allocation letter will not be necessary for. this amendment, I am requesting by copy of this memo that tech services review the proposed interim limits increase at this time Kent Wiggins Memorandum April 11, 1989 Page Two relative to instream water quality concerns in the French Broad River. The results of this evaluation should be placed with this file for review should additional flows to the MSD system be requested before expiration of this JOC. Also, please note that the JOC amendment includes those effluent monitoring requirements consistent with the proposed NPDES permit reissuance. It is recommended that the proposed JOC amendment be processed as rapidly as possible Should you have questions or wish to discuss this matter in more detail, please advise.

The modifications are required due to construction and operation of additional wastewater treatment works at the existing MSD Wastewater Treatment Plant. More specifically, the first modification requested is a "revision of the effluent limitations referred to in Stipulated Term 9(a) and defined'on Attachment A incorporated by reference as follows: Interim Discharge Proposed Discharge Effluent Characteristics Limitations Limitation BOD, 5 Day, 20°C 40 mg/1 60 mg/1 TSS 40 mg/1 75 mg/1 Fecal Coliform (geometric mean) 1,000/100m1 10,000/100m1 The reason for this request is that the required construction sequence for modifying the existing treatment works requires MSD to take a portion of the treatment works out of service to allow additional equipment to be placed in the Mr. R. Paul Wilms March 27, 1989 Page 2 same space. This increases loading on the remaining portions of the biological treatment process above the ultimate design capacity, leading to elevated BOD and TSS effluent concentrations. As a by-product of elevated TSS concentrations and replacement of existing chlorination equipment, the effluent concentrations of Fecal Coliform will be above the existing interim limits. The existing treatment plant has been and will continue to be operated to its maximum capacity during this interim period and all feasible activities will be undertaken to provide the highest level of treatment possible, but we do feel that the existing interim limits cannot be continuously met with the required construction sequence. MSD has purchased and installed additional aerators to improve BOD removal, and rerouted flow to improve TSS removal and Fecal Coliform reductions, but little else can be done to improve treatment efficiency without completion of the construction. The second modification requested is a revision of the time schedule defined in stipulated term 9(b) as follows: Activity 1. Complete construction of proposed additional treatment facilities 2. Achieve Compliance with final effluent limitations Existing Proposed JOC Dates JOC Dates March 1, 1990 July 1, 1990 July 1, 1990 October 1, 1990 The existing approved contract for additional treatment facilities has a completion date of February 19, 1990. Republic Contracting Company has requested a time extension of 72 days due to coordination and delivery of equipment. Although this time extension has not been granted, some contract relief is justified if it is allowable under the judicial order. With full approval of the request, the modified completion date would be May 1, 1990 and this does not include any subsequent delays which may come up in the next year. Therefore, and to prevent further modifications to the JOC, we request a completion of construction date of July 1, 1990. If this date is approved, a reasonable amount of time is required to allow the treatment process to achieve compliance with final effluent limitations. We propose that this date should be October 1, 1990. We respectfully request that you review this request to allow MSD to achieve compliance with the judicial order during this difficult time of construction. A one hundred dollar check payable to the North Carolina Department of Natural Resources and Community Development for administrative fees has been requisitioned and will be forwarded this week.

Waddey March 28, 1989 f ECE!Vf D Water Quat f t Sect;: n MAR 2 8 1989 Ashevilha - ,:. _Office .Asheville, 11 ;rtii Car LI na As you are aware, the Metropolitan Sewerage District was out of compliance with its' NPDES Permit limits on TSS and Fecal Coliform during February, 1989. The purpose of this letter is to summarize the problems that led to our noncom- pliance. Beginning February 15th, the plant's flow configuration was changed to accommodate the construction of RBC Basins #2 and #3. Since these future RBC basins will occupy the same space as our present activated sludge system, one half of the activated sludge system had to be taken out of service. About 60% of the Primary Microscreen effluent was treated by RBC Basin #1 and the Secondary Microscreens. The remaining 40% of the flow was treated by our one remaining activated sludge basin and secondary clarifier. The secondary clari- fier effluent was mixed with the RBC effluent as it entered the secondary microscreens. The problem has been the inability to pass an adequate amount of flow through the 21 micron secondary microscreens. The excess flow that can't be treated through the 21 micron screens passed into the four 149 micron screens. The 21 micron screens give adequate TSS removal but the 149 micron screens cannot produce a low TSS effluent. It is the water that passes through the 149 micron screens that has kept the plant from meeting its' TSS limits. March 28, 1989 Mr. Max Haner North Carolina Department of Natural Resources and Community Development Division of Environmental Management Page 2. To reduce hydraulic load to the secondary screens the secondary clarifier effluent was rerouted directly to the effluent launder. The additional benefit from this rerouting has been an improvement of our effluent due to the lower TSS coming from the secondary clarifier. We have taken measures to force as much flow as possible thru the 21 micron mesh screens. We have further reduced total flow to the secondary screens by sending more flow to our activated sludge system. The higher effluent TSS and BOD since February 15th, increased our chlorine demand to the point of our inability to feed enough chlorine, and so our Fecal Coliform counts have been high. The A Broker chlorinator from February 21st further worsened this particular problem. The chlorinator has been repaired, but the part needed for repair took three weeks to arrive. The 21 micron screens still cannot treat all of the secondary microscreen flow but the measures we have taken haveimproved the situation. Our most recent effluent TSS analyses have shown an improvement in our effluent. We will continue to make every effort to bring our effluent into compliance despite the current circumstances. Due to the high water levels in the French Broad River during this period, I don't believe our effluent would have impacted water quality standards in the River. Please advise me if I can provide further information. Sincerely, 4401E/ E, arc Fender EMF/cnr SUMMER QW=26.63 MBD, BOD5=60, NH3=20 Beg # ( Reach # ( Beg Ili D.O.
