The existing and proposed conditions should match the existing permit requirement of monthly monitoring. Also, the cyanide limit was in error. The existing and proposed limit should be 5.3 ug/l, as in the existing permit. I have enclosed a copy of the corrected factsheet. Please call me if you have further comments or questions.

I WLA Notes SRB 4/9/93 CMUD Mallard Creek WWTP NCO030210 - CMUD has applied for an expansion of the Mallard Creek WWTP from 3.0 to 6.0 MGD. September 25, 1989, a permit was issued for flows of 3.0 and 6.0 MGD with a condition stating that the permit may be re -opened for possible change in effluent limits pending instream information including the calibration of a QUAL2E water quality model. Since that time, a QUAL2E model has been calibrated and was released on March 31, 1993. - Over the past 12 months the Mallard Creek WWTP has been in compliance. No DO violations were recorded at the upstream or downstream self monitoring stations over the past 12 months. As of November, 1992, monthly flows have averaged over 3.0 MGD. - The QUAL2E model predicts that at 6.0 MGD, the Mallard Creek WWTP should receive the following summer limits in order to prevent the facility from contributing to DO violations in Mallard Creek and the Rocky River: 5.0 mg/l BOD5, 2.0 mg/1 NH3 N, and 6.0 mg/1 DO. It is recommended that winter limits be bases upon the same summer to winter ratio as in the current permit. This will result in winter limits of 10.0 mg/1 BOD5, 4.0 mg/1 NH3 N, and 6.0 mg/l DO. - To prevent chlorine toxicity instream, the facility at 6.0 MGD should meet 18.1 ug/l chlorine. - According to Joe Pearce, Mallard Creek has not yet identified all of their Industrial Users. Therefor there is insufficient data available to update the toxics spreadsheet. Toxics limits will be renewed at existing limits. r 1 + r - •m Seff-Monitoring Data Monthly Averages Discharger: CMUD Mallard Creek PermR Number: NCO030210 Receiving Stream: Mallard Creek 030711 Me TIOM • - - -- - - FT, mool • o --- --- 75 --- --- Dr— rM • • - - -- - Facility: Mallard Creek WWTP AMMONIA ANALYSIS: SUMMER 7010: 0.64 cfs NH3-N Effl.

This model was used to predict dissolved oxygen and biochemical oxygen demand concentrations at low flow conditions for both permitted and summer average discharge conditions. The general objective of this project was to provide a tool to assist with management of wastewater discharge issues in the upper watershed of the Rocky River. A more specific objective of the project was to provide a model that could be used to determine the appropriate waste load allocation for the Charlotte -Mecklenburg Utility Department (CMUD) Mallard Creek WWTP. CMUD has applied for an expansion of the Mallard Creek WWTP from 3 to 6 MGD. Results from this model indicate that water quality in the upper watershed of the Rocky River is not adequately protected by the current NPDES permit effluent limits. Under current operating conditions, that are well below permitted loads, the DO standard is not predicted to be violated in the Rocky River study area. However, three DO sags are predicted to drop to or near the stream standard, indicating that little assimilative capacity remains for oxygen consuming wastes. It is recommended that no new or expanded discharges be permitted in the study area unless an evaluation of engineering alternatives shows that it is the most environmentally sound alternative. If new or expanding discharges are permitted, they should receive best available technology limits in the watersheds above the confluence of Mallard Creek and the Rocky River, due to severely limited assimilative capacity. Any new or expanding discharge in the lower watersheds of the Rocky River should receive a total BODu limit of 32 mg/1 or less, equivalent to 10 mg/l BOD5 and 4 mg/1 NH3 for typical domestic discharges. This level of treatment will protect the DO standard as well as preventing any one discharge from using up 100 percent of the available assimilative capacity of the river. In addition, it is recommended that Mooresville WWTP, Mallard Creek WWTP, and Concord'' WWTP be encouraged to continue to meet advanced treatment levels. Upon expansion or modification, Mooresville WWTP and Concord WWTP should receive more advanced treatment requirements that will protect water quality in the Rocky River. This will mean advanced tertiary treatment at the Mooresville WWTP and limits at least as stringent as 10 mg/l BOD5 (5.7 mg/1 CBOD5) and 4 mg/1 NH3 at the Concord WWTP. ii I. INTRODUCTION A QUAL2E river model covering 47.6 total stream miles in the Rocky River basin has been developed. This model will allow DEM to evaluate interaction among wastewater treatment facilities in the region. Three major facilities in the area (Mooresville WWTP, CMUD Mallard Creek WWTP, and Concord Rocky River Regional WWTP) have expressed interest in expansion. In addition, CMUD is considering a new 3.0 MGD facility (River Run) above the confluence with the West Branch Rocky River, Cabarrus County has proposed an 1.8 MGD facility below the confluence with Muddy Creek, and the City of Kannapolis is considering its own 5.0 MGD WWTP. Previous modeling efforts on the Rocky River were limited to relatively small sections of the river so that no one model was capable of integrating the effects of each of the major discharges to the river system. This left doubts as to whether additional waste discharges could be permitted, even at state of the art treatment levels. Thus, this larger scale effort was undertaken to fill gaps between models and to develop a basinwide planning tool that would utilize the best available information to examine the study area more closely. Three QUAL2E models calibrated for adjacent segments of the Rocky River were combined into one model for the purposes of waste allocation. The allocation model contains reaches from the following calibrated models; the Mooresville WWTP model, completed November 1988, the Mallard Creek WWTP model, completed October 1992, and the Concord Regional WWTP model, completed January 1988. The allocation model covers 42.8 miles of the Rocky River as well as short segments of Dye Branch, West Branch Rocky River, and Mallard Creek. II. DESCRIPTION OF STUDY AREA The Rocky River drains 3 subbasins of the Yadkin River Basin; 03-07-11 through 03-07-13.1 The river flows from its headwaters near Mooresville, NC, to its confluence with the Pee Dee River below Lake Tillery. This study focused on a 42 mile section towards the upper end of the Rocky River. The study area includes the Rocky River from its confluence with Dye Branch downstream to 2 miles below the confluence with Muddy Creek. Three tributaries are also modeled; Dye Branch below the Mooresville WWTP, West Branch Rocky River below the Mid South discharge, and Mallard Creek below the Mallard Creek WWTP (Figure 1). The 7Q 10 on the Rocky River rises from 0.3 cfs above Dye Creek to 28 cfs below Muddy Creek. Including the three modeled tributaries; Dye Branch, West Branch, and Mallard Creek, 10 major tributaries join the Rocky River in the study area. These tributaries and their average and 7Q 10 flows, as estimated by the USGS, are presented in Figure 2. Three major facilities discharge to streams in the study area. Mooresville WWTP is currentl' permitted to discharge 5.2 MGD to Dye Creek and is considering an expansion to 7.8 MGD. The Mallard Creek WWTP currently discharges 3.0 MGD to Mallard Creek and is building an expansion to 6.0 MGD. Concord Regional is permitted Dye Branch Mooresville wwra Figure 1.

Even without considering these minor facilities, wasteflow dominates streamflow at 7Q 10 conditions throughout much of the study area (Figure 3). Clearly, the Rocky River is heavily utilized for the assimilation of wastewater. III. CALIBRATION METHODS Calibration of this model was done in three phases, each discussed under separate covers. Calibration of the four upstream reaches, covering Dye Creek, West Branch, and the Rocky,'River from Dye Creek to West Branch, is presented in the Mooresville Model, dated November 30, 1988 (NCDEM 1988a). Calibration of the middle eleven reaches, including Mallard Creek, is presented in the Mallard Creek Model, dated October 14, 1992 (NCDEM 1992). Calibration of the bottom four reaches is presented in the Concord Model, dated January 14, 1988, and in an addendum to that memo, dated April 3, 1989 (NCDEM 1988b). Linking the three models into one allocation model was done without changing any of the reach specific hydraulic or decay rate parameters. Headwater elements for the two downstream models were replaced with the downstream element of the respective upstream model. This resulted in new "headwater" conditions for these downstream reaches which allowed for the analysis of interaction between all dischargers in the study area. The only reach specific parameter that was changed in the allocation model was incremental flow. This was necessary to achieve a flow balance of predicted 7Q10 flow throughout the study area in agreement with USGS flow estimates. A comparison of upstream and downstream USGS flow estimates indicated that an incremental flow of 0.052 cfs/mile was appropriate under 7Q 10 conditions. This incremental flow, in combination with tributary flows provided by the USGS, produced a flow profile that follows the pattern of USGS flow estimates (Figure 4). The model predicts higher flows than the USGS estimates at the bottom of the study area. This is primarily a result of high USGS estimates of tributary flow. However, the difference is less than 10 percent. IV. SENSITIVITY ANALYSIS A first order error analysis was used to determine the relative sensitivity of the model to parameter estimates. QUAL2E-UNCAS was run to determine which inputs most influenced model estimates of DO, BOD, and ammonia (NH3). Every model parameter was independently varied by 5 percent and the response in terms of DO, BOD, and NH3 was recorded at five locations throughout the study area. The five locations chosen to evaluate model sensitivity are: the three DO sags observed in the calibration data sets (reaches 8, 13, and 18), at the bottom of Mallard Creek, and at the bottom of the study area., The sensitivity of predicted DO concentrations to model perturbation is presented in Table 1 a. Predicted DO was most sensitive to the initial temperature of the river. This sensitivity is expected due to the relationship between temperature and DO saturation and is not a limitation to the predictive ability of the model. Predicted DO was also sensitive 4 Figure 3.

This also is not surprising since the reaeration rate is determined by the hydraulics. Point load BOD, BOD decay, point load DO, and sediment oxygen demand (SOD) also displayed a significant effect on predicted DO throughout the study area. In general, initial temperature and the velocity exponent had significantly greater effect upon DO than any other parameters. Point load DO had the next highest effect, an encouraging result since good estimates are available for this control parameter. The sensitivity of predicted BOD concentration to model perturbation is presented in Table lb. Predicted BOD was most sensitive to Point load BOD, clearly to be expected considering the high instream waste concentration throughout the study area. As with predicted DO, initial temperature and hydraulic equations were important to predicted BOD. Predicted BOD was also sensitive to BOD decay and BOD settling. The sensitivity of predicted NH3 concentration to model perturbation is presented in Table 1 c. As with predicted DO and BOD, predicted NH3 was most sensitive to initial temperature and point source loading. Not surprisingly, predicted NH3 concentrations were also somewhat sensitive to NH3 and NH2 decay rates. In general the model showed sensitivity to initial temperature, the hydraulic equations, and point source loading. Confidence in these parameters tends to be high since estimates of initial temperature and point source loading are defined by design conditions, and the hydraulic equations were developed from field studies. This suggests that the model is relatively unsensitive to variation of parameters for which default or literature values were used. V. WASTELOAD ALLOCATION 1. Background Conditions Design conditions for allocation model runs were defined as 7Q 10 flows (see Figure 2), 75th percentile temperature for the Sub -basins (26 degrees C.), 90% DO saturation, and the following chemical concentrations; 2.5 mg/1 CBODu, 0.40 mg/1 organic nitrogen, 0.1 mg/l NH3-N, and 0.28 mg/1 NOx. These background estimates designed to reflect typical background surface water quality in North Carolina during low flow conditions and are consistent with typical values reported by the EPA (Brown and Barnwell 1987). Further discussion of background conditions can be found in the three calibration documents (NCDEM 1988a, 1988b, 1992). 2. Wastewater Conditions. Effluent characteristics of facilities discharging to the study area were modeled using current permit limits, flow information from the permit modification, and information from compliance monitoring data. Permit limits for DO, BOD, and NH3 for the three major facilities are listed in Table 2a. Actual effluent discharge conditions were determined by examining compliance monitoring data and are presented in Table 2b. Actual conditions were estimated by the 1991 mean NH3 and BOD concentrations and the 1991 minimum monthly average DO for each major facility. For model input, BOD5 values were converted to CBODu estimates using CBODu to BOD5 ratios. CBODu/BOD5 ratios were calculated from ultimate BOD 7 Table 1 a.

Results Predicted DO profiles of the Rocky River study area for existing permit and actual conditions are presented in Figures 5a and 5b. Permit conditions are predicted to result in two DO sags which drop below the 5.0 mg/l DO standard. The first sag occurs 16 miles below the Mooresville WWTP in an area where river velocity is at its minimum. The second sag occurs directly below the Concord WWTP. Because actual effluent concentrations are well below permit levels the depth of both of these sags is greatly reduced. No DO violations are predicted under current discharge conditions although DO is predicted to drop to the stream standard of 5.0 mg/l below the Mooresville and Mallard Creek WWTPs. Predicted BOD profiles indicate that under existing permit conditions, Mooresville WWTP and Concord WWTP control BOD concentrations throughout the study area (Figures 6 and 7). Under actual conditions Concord is less important and loading from Coddle Creek and Back Creek contribute to the shape of the BOD profile. Mallard Creek WWTP, while dominating BOD concentrations in Mallard Creek below the outfall, does not significantly effect BOD concentrations along the Rocky River under existing permit or actual conditions. The model was used to determine what effluent limits would prevent DO violations at 7Q 10 conditions. The effluent concentrations of NH3, DO, and CBOD for the three major WWTPs were varied to determine the maximum allowable concentrations to maintain DO standards. The following sets of effluent concentrations were obtained: Mooresville WWTP Mallard Creek WWTP Concord WWTP Flow: 5.2 MGD Flow: 6.0 MGD Flow: 24 MGD DO: 6.0 mg/l DO: 6.0 mg/I DO: 6.0 mg/l NH3: 1.0 mg/1 NH3: 1.0 mg/l NH3: 4.0 mg/1 BOD5: 7.0 mg/l BOD5: 5.0 mg/l (4 mg/l CBOD5) BOD5:20 mg/l (11 mg/1 CBOD5) These maximum discharge concentrations that protect the DO standard can be used to determine the total maximum daily load (TMDL) during 7Q 10 conditions for specific river, reaches. Because these discharge conditions are the result of an allocation procedure that allowed DO to drop to the DO standard, any additional loading is predicted to result in DO violations. The instream concentration of total BOD at the beginning of each DO sag represent the predicted TMDL for that point under the given background and wastestream conditions. The instream concentration of total BOD at the minimum of each DO sag represents the predicted DO equilibrium point for the stream DO standard': Total BOD concentrations above the equilibrium point will eventually drive DO below the stream standard. Therefore, the total BOD concentration where an equilibrium i reached at the stream standard can be considered as a TMDL for the stream 12 Figure 5a.

This estimate of the total BOD TMDL does not include a margin of safety but can be used to guide management decisions. Using this method to determine the TMDL for total BOD, it is clear that the TMDL has been approached or exceeded for the upper reaches of the study area. Under existing conditions, the DO sag below the Mooresville WWTP reaches a minimum of 5.0 mg/l. At 5.0 mg/1 DO, equilibrium is predicted at 12 mg/1 total BODu. Any change in wastewater discharge conditions that increases the IWC of total BODu above 12 mg/1 in the region of the DO sag is predicted to result in a DO violation. A similar case exists on Mallard Creek where the DO minimum reaches 5.0 mg/l. DO violations are predicted in Mallard Creek if the IWC of total BODu is raised. DO Equilibrium is not reached because DO levels are still falling in Mallard Creek at its mouth. The TMDL of total BOD for the lower reaches of the study area is considerably higher than the TMDL above Mallard Creek due to higher stream velocities and greater flow. Waste allocation performed at the Concord WWTP outfall indicates that at 5.0 mg/1 DO, the equilibrium total BODu concentration is 32 mg/l. Below the recovery zone for the Concord WWTP, an IWC of approximately 45 mg/1 BODu is required to -drop DO back to 5.0 mg/l during 7Q 10 conditions. The model was also used to evaluate the effect on DO of ten scenarios of possible discharge conditions in the study area. A brief description of these scenarios and the predicted impacts on DO concentrations are presented in Table 3. VI. RECOM ENDATIONS At present, water quality in the upper watershed of the Rocky River is not protected by the permitted wastewater flow. Wastewater discharge from the Mooresville and Concord WWTPs at permitted discharge conditions are predicted to result in downstream DO violations during 7Q 10 conditions. Because both of the facilities presently meet effluent BOD concentrations below permitted levels, the DO standard is not expected to be violated in the Rocky River study area under current operating conditions. However, even with the three major WWTPs in the study area operating at or near tertiary treatment levels, the model predicts two DO sags that drop to the stream standard of 5.0 mg/l. This suggests that the total maximum daily load (TMDL) for oxygen consuming wastes has been met or exceeded for portions of the study area. Because of the heavy use of the Rocky River for the assimilation of wastewater and the likely future demand for additional wastewater discharge, it is recommended that a basinwide wasteload allocation strategy be developed. Such a plan would consider potential interaction between all sources of oxygen consuming wastes in the basin and allow for anticipated future wastewater discharge needs. This general strategy will be part of DEM's basinwide plan for the Yadkin River basin, due to be completed July of 1998. The following proposed basin strategy for the Rocky River study area is intended as a watershed component of a larger and more general basinwide plan for the Yadkin River basin. 16 Table 3.

The Rocky River study area can be divided into four regions where distinct assimilation processes exist. These are, 1) the Rocky River watershed above Mallard Creek, 2) the Mallard Creek watershed, 3) the Rocky River and tributaries from Mallard Creek to below the Concord WWTP DO recovery zone, and 4) the Rocky River below the Concord WWTP DO recovery zone. For each of the river regions the TMDL for oxygen consuming wastes can be estimated and a management strategy developed. The DO sag below Mooresville is predicted to reach a minimum of 5.0 mg/1 during 7Q 10 conditions. This indicates that under existing discharge conditions, no further assimilative capacity is available in the Rocky River from the Mooresville WWTP outfall to the confluence with Mallard Creek. This reach of river is sensitive to oxygen consuming wastes due to relatively slow velocities. It is recommended that new and expanding discharges to the Rocky River and Dye Branch be permitted only if no reasonable alternative exists, and then only at best available technology treatment levels. New and expanding discharges to tributaries to the study area above Mallard Creek should be permitted only at best available technology levels unless modeling shows that DO sag is complete before entering the Rocky River or Dye Branch. The Mallard Creek WWTP takes up essentially all of the available assimilative capacity for oxygen consuming wastes in Mallard Creek, as shown by the predicted DO sag to 5.0 mg/1. For this reason is recommended that new and expanding discharges to Mallard Creek only be permitted if no reasonable alternative exists, and then only at best available technology treatment levels. New and expanding discharges to tributaries to the study area above Mallard Creek should also be permitted only at best available technology levels unless modeling shows that DO sag is complete before entering Mallard Creek. The section of the Rocky River from below Mallard Creek to below the Concord WWTP DO recovery zone has significantly more assimilative capacity than upstream reaches. This is due to greater flow and relatively high stream velocities. Still, the TMDL for this river segment has been exceeded by the existing Concord WWTP permit limits. Examination of the allocation model indicates that at 7.Q10 conditions, DO will recover from 5.0 mg/l only if the ultimate BOD (BODu) concentration is less than 32 mg/l. It is therefore recommended that no new or expanded discharges be allowed unless an evaluation of engineering alternatives shows that it is the most environmentally sound alternative. For this river region the minimal level of treatment for new or expanding wastewater discharges should include a total BODu concentration of 32 mg/l, equivalent to 10 mg/l BOD5 and 4 mg/1 NH3 for typical domestic discharges (or 12 and 3). This limit will allow new and expanded facilities to discharge to the Rocky River without contribution to further demands on the already heavily utilized assimilative capacity. Below the Concord WWTP DO recovery zone, assimilative capacity is presently available. However, the instream waste concentration is above 60% at 7Q10 conditions and future demands may increase it further. It is recommended that all new and expanding discharges receive a total BODu limit of at least 32 mg/1, equivalent to 10 mg/1 BOD5 and 4 mg/l NH3 for typical domestic discharges. This concentration is equal to the predicted instream concentration below the Concord WWTP that would just protect the DO 18 standard. This level of treatment will protect the DO standard as well as preventing any one discharge from using up 100% of the available assimilative capacity of the River. In addition to these watershed specific recommendations, it is recommended that the three major WWTPs be encouraged to continue to meet or exceed their current level of treatment. Upon expansion or modification, Mooresville WWTP and Concord WWTP should receive permit limits that will protect water quality in the Rocky River. This will require tertiary treatment at the Mooresville WWTP as well as improved treatment technologies at the Concord WWTP. 19 REFERENCES Brown, L. C., and T. O. Barnwell, 1987.
