The plant is designed at 2.5 MGD and is currently discharging an average of 1.413 MGD. The current summer limits for GODS and NH,-N are 5 mg/1 and 2 mg/1 respectively. Compliance data indicate that the facility exceeded these limits from June to September, 1987. While the additional wasteflow is not expected to result in a significant impact, the proposed JOC limits allow for extended anoxic conditions at low flow. Since the facility seems to be capable of performance beyond proposed levels, it is recommended that more stringent (summer) limits be considered. A DEM bioassay from 2/12/86 indicated no acute toxicity. Since the town of Whiteville is a major facility (> 1 MGD) with an industrial component, it may be beneficial to require quarterly chronic monitoring. Analysis and Discussion Model runs were completed at 1.413 MGD r (post-JOC flow) at the suggested JOC limits of 10Jmg/1C 1BOD and 4 1.463 1 NH.,-N. It was assumed that the NBOD:NH;,-N ratio was4.5:1S whileltheg/ CHOD:BODS ratio was 2:1 since 10% of the waste is industrial. Other model inputs were obtained from an analysis done for Whiteville's 1.986 permit renewal. These runs predicted that the in -stream DO sags to 0 approximately 1.1 miles (pre-JOC) and 1.0 miles (post-JOC) downstream from the outfall. Based on this comparison alone, significant impact as a result of the addi- tional flow is not anticipated. Other model runs were completed to determine "background" conditions, the effects of reducing JOC NH:,-N limits and the effects of varying temper- ature and flow on in -stream D0. The results (Table 1) also support the conclusion that the increased waste flow does not affect the DO. Since D0 values less than 3 mg/1 may be expected to have both acute and chronic impacts, reducing the allowable BOD, and NH.-N in the JOC would provide substantial protection to the stream. Since the facility seems to be capa- ble of meeting limits below proposed JOC limits, it is recommended that consideration be given to raising the DO limit to 6 mg/1 and lowering the NH.,-N limit. An NH,-N limit of 4 mg/1 is necessary to maintain DO above 3 mg/1 instream. An analysis was not completed to determine the maximum allowable JOC flow because of the lack of applicable criteria when predicted DO values are below 3 mg/1. Please advise if questions.
