The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised *February 1987) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is —�—% (defined as treatment two in the North Carolina procedure document). The permit holder shall perform quarterly monitoring using this procedure to establish compliance with the permit condition. The fast test will be performed after thirty days from issuance of this permit during the months of 'Sag �__.Se( Dei . Effluent sampling for this testing shall be performed at the NPDE9 permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP313. Additionally, DEM Form AT-1 (original) is to be sent to the following address: Attention: Technical Services Branch North Carolina Division of Environmental Management P.O. Box 27687 Raleigh, N.C. 27611 Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival and appropriate environmental controls, shall constitute an invalid test and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute a failure of permit condition. 7Q10 264.5 cfs PermitedFlow (e.435 MGD IWC% 3.149 Basin & Sub -basin 03o4o5 Receiving Stream Pease- River County WoLgge.

No modifications are proposed at either plant. Due to the close proximity of sev- eral large dischargers in this area of the Neuse River, a QUAL2E model was used to examine the interaction of these facilities at their current permitted load- ing. At the currently permitted loading dissolved oxygen sags below S mg/l are predicted below the Goldsboro facility and below the Kinston and DuPont facili- ties (see attached). Interaction with Weyerhaeuser may also result in predicted dissolved oxygen violations, however, model uncertainty is very high in this area. Dissolved oxygen problems are not predicted at actual current loading. Both the Goldboro and Kinston facility appear to be capable of meeting more stringent limits than currently permitted (see attached DMR data). Goldsboro's instream monitoring data indicate dissolved oxygen problems were occurring in the past when loading was closer to the permitted loading. Goldsboro recently brought a new plant on line which has significantly reduced loading. New permit limits for Goldsboro and Northside WWTP appear to be attainable with existing facilities. A D.O. minimum of S.D mg/l is predicted at this load- ing, however, due to the level of model uncertainty and the contribution of sev- eral other facilities in the area to the D.O. sag, this may be the most appropriate short-term course of action. Model Development_ Hydraulics: A time -of -travel (TOT) study was performed below the Goldsboro facility in 1979. Gaging stations are located at Goldsboro and Kinston from which hydraulic power functions were developed. The power functions estimated from the Goldsboro station predicted TOT that closely matched the 1979 TOT, therefore, these power functions were used in the QUAL2E model for reaches down to Kinston. The Kinston gaging data is the only source of hydraulic information in this area of the river. East Carolina performed a TOT study below Contentnea Creek which indicates a significant reduction in velocity. This area is just above tidal influence and appears to be very swampy. Model uncertainty in the hydraulic parameters increases moving downstream from Goldsboro. Qualitatively, this uncertainty is probably fairly low until Contentnea Creek. Kinetics: No reliable field information is available for developing the kinetic parameters. CBOD and NH3 decay rates were estimated using the LB equa- tions. The Tsivoglou and Wallace option in QUAL2E was used for reaeration. All model data sets, data used for model input, and model output are attached. Recommendations Time -of -travel studies should be performed on the Neuse River with the fol- lowing priorities: 1) Hwy 11/55 to Contentnea Creek 2) Contentnea Creek to Streets Ferry 3) SR 1915 to Hwy 11/55 4) SR 1008 to SR 1915 Synoptic water quality sampling studies should be performed throughout the area. DuPont's permit expires in April 1990, therefore, emphasis should be placed in refining the model in this area. Contentnea MSD, Kinston -Peachtree, and Genoa Industrial Park expire in 1992 and Cherry Hospital expires in 1993. We should aim at having a reasonable model for developing equitable permits by 1992.
