Nowell'M� SUBJECT: Instream Assessment for the Town of Boone WWTP NPDES Permit No. NC0020621 Watauga County SOC Case#94-08 mm The Technical Support Branch has completed the instream assessment in response to the SOC request for the Town of Boone. The Town wants to increase the flow of the plant by an additional 125,000 GPD of domestic wastewater with an interim increase in their effluent limitations for BODS and TSS. A review of the self monitoring data for BODS show that the limit of 30 mg/1 has been exceeded from November, 1993 through April 1994 and the TSS limit of 30 mg/l has been exceeded three of the last five months. Regional Office staff indicate that the permit violations are.due to inadequate solids handling by the treatment facility. The impact of Boone's WWTP wasteflow on dissolved oxygen (DO) levels in the South Fork New River was evaluated using Technical Support's Level B modeling framework. The results of this analysis indicate that the requested wasteflow increase of 125,000 GPD and the interim SOC limits of 45 mg/1 of BODS and 45 mg/l of TSS will have very little impact on the stream and that EMC approved 67(b) criteria will be satisfied. As future reference, our evaluation determined that Boone could increase their wasteflow by 766,000 GPD to the design capacity of 3.2 MGD and not cause a significant impact of more than 0.5 mg/l of DO sag or extend the streamlength predicted to violate the DO standard by more than 0.5 miles. Technical Support recommend that the facility continue to perform chronic whole effluent toxicity testing at 27% on a quarterly basis. Analysis and Discussion The Town of Boone discharges into the South Fork New River located in the New River Basin. The receiving stream has a classification of C and is located 62 miles upstream of the segment of the New River that has been reclassified as C ORW. Specific management strategies hai been approved to protect the exceptional resource waters of the New River Basin, which include stormwater controls, designated limitations for new and expanded dischargers, and safety factors for toxic discharges. U.S.G.S. flow data indicate the summer 7Q10 flow at Boone's discharge.point is 13.1 cfs, with a drainage area of 32.7 square miles and an average flow of 77.8 cfs. Memorandum to Steve Mauney page 2 Facility compliance data for January 1993�-bad December 1993 report the average monthly wasteflow as 2.434 MGD (pre-SOC flow). The amount of flow requested by the SOC is 0.125 MGD. The requested post -SOC flow is 2.559 MGD with 45 mg/1 of BODS and 45 mg/1 of TSS. In addition, a fecal limit of 200/100m1 and a pH limit of 6-9 S.U. has also been requested during the SOC period. A Level B modeling analysis was used to assess the impact of the Boone discharge on dissolved oxygen in the receiving stream. A total of three model runs were made: 1) at the pre-SOC flow (2.434 MGD), 2) at the post SOC flow (2.559 MGD), and 3) at the design flow (3.2 MGD). The waste input for CBOD reflected the Winston-Salem Regional 'Office's recommendation of a BODS limit of 45 mg/l. Using a CBODBODS multiplier of 1.7, based on a long term BOD analysis, the CBOD input was 76.5 mg/l. The NBOD input was determined by using Boone's maximum monthly NH3 value for the past year. The highest NH3 value was 20 mg/1: this yields an NBOD input of 90 mg/l (using a NBOD/NH3 multiplier of 4.57). The model results at 2.434 MGD and 2.559 MGD predict DO minimums of 5.84 mg/1 and 5.77 mg/1, respectively. The minimums occur 0.4 miles downstream of the discharge and reflect a difference of only 0.07 mg/l. The results of the models run at the design flow of 3.2 MGD indicate a DO minimum of 5.42 mg/l. With a difference of only 0.42 mg/1 between DO minimums for the pre- SOC flow and design flow run, this is considered an acceptable range and meets the 67(b) criteria. Complete model results will be presented in Table 1. Recommendation Based on the Level B model results, Technical Support recommends approval of 0.125 MGD additional Wasteflow for the Banner Elk WWTP with the SOC limits for BODS, TSS, fecal coliform and pH. cc: Jeff Bouchelle Dave Goodrich LWLAFile ' Table 1.
