The City has requested an SOC because their facility is out of compliance with its TSS limit. The City would like to relax its limits for TSS, and BODS while adding 0.145 MGD of wasteflow. With the addition of 0.145 MGD to the existing 1.1 average MGD, the plant will reach its permitted flow of 1.25 MGD. In addition, the City plans to expand its facility to 2.5 MGD after the SOC. A Level-B analysis was performed to assess the impact of the additional flow and relaxed BODS limits. The modeling analysis for this assessment indicates that the additional wasteflow under the proposed interim limits will cause a violation of EMC 67(b). The instream Dos are predicted to drop well below 5 mg/1 (as low as 0.68 mg/1) under both the existing and SOC conditions. The DO under SOC conditions is 1.68 mg/l less than under the pre-SOC conditions, a violation of the 67(b) criteria allowing a decrease of only 0.5 mg/l. Additionally, the DO is less than 5 mg/l for greater than 0.5 miles under both existing and SOC conditions, another violation of 67(b) criteria. Since the 67(b) criteria are violated at the existing wasteflow (1.1 MGD), no additional volume of wasteflow will meet 67(b) criteria at the proposed SOC limits. Technical Support recommends no additional flow be allowed under the SOC due to the predicted degraded water quality conditions. As a condition of the SOC, the City must obtain an NPDES permit modification for a higher wasteflow, 2.5 MGD. Based on Level-B model predictions, stringent water quality limits must be met at the expanded wasteflow. Speculative limits are BODS - 5 mg/l, NH3-N - 2 mg/l, and DO = 6 mg/l. These limits are needed to protect the DO standard of 5 mg/l above Worthville Dam. Revised instream monitoring is recommended as part of the SOC to confirm the modeling results. In 1988, Technical Support recommended instream monitoring above Worthville Dam to determine the extent of the DO sag. However, this request was not included in the permit. The only available downstream data are collected below the dam in a heavily aerated area. Thus, the downstream data are not representative of the DO sag. Downstream monitoring is recommended at two sites, 1.) above Worthville Dam and 2.) above the confluence of Hasketts Creek, the area of a second predicted DO sag. An additional concern is the proposed Randleman Lake upstream of the discharge site which would change the flow regime of the Deep River. Background Information The City of Randleman WWTP discharges into Deep River, a class "C" stream. The Deep River drains approximately 180 square miles at the discharge site. The USGS estimates the following flows at the discharge site: summer 7Q10 = 5 cfs, winter 7Q10 - 12 cfs, and average flow - 171 cfs. The creek is slow moving with a stream bed gradient of 4.8 feet per mile. An updated Level-B model was performed in 1988 for the facility's permit renewal. A new allocation was needed since Randleman had incorrectly been assigned secondary limits in its previous permits and water quality violations were evident. The new model allocation produced limits of BODS = 6 mg/l and NH3-N 2 mg/1 at 1.25 MGD. However, a compromise was reached and the limits of BODS = 28 mg/l and NH3-N - 2 mg/l were assigned based on the plant's existing treatment. In addition, a stream survey was recommended in order to better calibrate our model. Due to resource constraints and priorities, this study was never conducted. Analvsis and Discussion The model was run with the facility's existing effluent limits of BODS = 28 mg/l and NH3-N - 2 mg/l at the pre-SOC flow (1.1 MGD). The BODS and NH3-N parameters were input to the model as CBOD and NBOD using multipliers of 2.0 for BODS and 4.5 for NH3-N (see Table 1). When these effluent characteristics were input to the model, the predicted DO sag was 2.36 mg/1 at milepoint 0.4 (see Table 2). The model was then run with the region's requested effluent limits of BODS = 40 mg/l and NH3-N = 2 mg/l using the SOC flow (1.25 MGD) to check against 67(b) criteria. Level-B modeling analysis predicted that the requested flow and existing limits will cause a DO sag of 0.68 mg/l at milepoint 0.4, a decrease of 1.68 mg/l. Since the facility will expand to 2.5 MGD at the end of the SOC, model runs were conducted at the increased flow in order to determine effluent limits. The model predicts that limits of BODS = 51 NH3-N - 2, and DO = 6 mg/l will be required to meet the DO stream standard of 5 mg/l. cc: Steve Tedder Kent Wiggins Central Files TABLE 1.
