The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is 90 % (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 first test will be performed after thirty days from the effective date of this permit during the months of Feb., May, Aug., and Nov. Effluent sampling for this testing shall be performed at the NPDES 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 TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy Creek Road Raleigh, N.C. 27607 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 single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will revert to quarterly in the months specified above. 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 noncompliance with monitoring requirements. 7Q10 1.3 cfs Permitted Flow 12.0 MGD IWC 93.5 % Basin & Sub -basin 03-0e07 Receiving Stream Contentnea Creek County Wilson QCL PIF Version 9/91 Recommended byr--4 Date 3MAa i. rvvi Farrell K= •ugh .Facility Name: Permit Number: Engineer: Subbasln: Receiving Stream: USGS quad #: Request Number: Date: Expiration date: City of Wilson - Hominy Creek WWTP NC0023906 Bolden 03-04-07 Contentnea Creek E27NW 7754 2/22/94 2/28/94 Existing WLA checked: x Staff Report: x Topo checked: x USGS Flows confirmed: PIRF / APAMS: nr IWC Spreadsheet: nr Stream Classification: x Nutrient Sensitivity: x lnstream Data: x l,‘aeac.3 P ttrw i Cw4exr n,,il3 (ctY tot -30e9 -zf-165 Don1 Coas-VIA 6,0k, 833-115 Z ( coNSl/tf ( N L!✓�IA f�. f- -OCX-kLOLN "") • J011 P1Gc-ve-T (l (a N1 AM) Yee-) Brief of WLA Analysis Previous WLA's 1975: Modeling Analysis derived limits of 5 / 2 / 5 (for 10.0 mgd) 1982: Re -issued with same limits (two WLA's this year, 2nd fact sheet had winter limits on final WLA) 1984: expanded flow to 12.0 mgd. Same limits. No toxics limits at this issuance. 1989: Re -issued with same domestic, tertiary limits. Toxics included in this WLA In the 1989 WLA review, a model for the proposed expansion of Buckhome Reservoir was looked into. The modeling analysis for the reservoir expansion extended past the Wilson discharge, but (per note from Trevor) the "conclusions assume reaeration decreases rather than increases w/ increased flow." The recommendation was to monitor downstream of the outfall; findings from this monitoring indicated upstream WQ is lower than the downstream. In 1983 a Level B was performed on this discharge and it indicated that DO violations would occur -13 miles below the discharge. Unfortunately, after talking with the Modeler II who developed this model, it seems that Wiggins Mill was not taken into full account, (i.e. the stream was modeled after Buckhorne Reservoir without including Wiggins Mill's lower release and lower DO's). Nonetheless, the facility is permitted with advanced tertiary limits and changes in the Buckhorne Reservoir and Wiggins Mill capacities and required releases are still in the works. Flows in this area have proven very difficult to determine. During review of the Willow Springs Country Club, (just upstream of Wilson, directly below Wiggins Mill outfall) I contacted Charles Pittman [Town of Wilson] and he said that there is no minimum release required at Wiggins Mill Dam. They usually maintain a 1.0 cfs at that dam. I asked for a letter confirming this, but written in such a way as to absolve him from any liability; he wouldn't commit to sending me one. When the Buckhorne Reservoir expansion is complete, Wiggins Mill will be the regulated discharge point and it will be set at 4.7 cfs. No date for completion of this project could be established since an endangered species is present and Marine Fisheries is holding up the proposed expansion. Previous wasteloads for this facility were determined with a regulated 1.3 cfs. Since there is approximately 2 river miles between Willow Springs and Wilson, an additional 0.3 cfs would probably be appropriate; there is now way to accurately define a drainage area in this pocosin. Continuing with a 1.3 cfs regulated flow will also make any administrative problems easier to deal with. The Buckhorne Reservoir and Wiggins Mill are still slated for expansion and their regulated flows should be well established by then. 1 March 1994: telephone conversation with Russell Brice 399 - 2491 [Superintendent Wilson WWTP ] asked about chlorine limit. I did not specify if he would receive a limit, (facility is not modifying, therefore we can't give one) or what it would be; he was under the assumption that he would be receiving a 17 µg/I chlorine limit. His chlorine levels are very high and his fecal levels are very low. I told him to contact Barry Honeycutt and work out a better method of lowering his chlorine levels. His chlorine contact is through the effluent channel. He informed me that he would try using Vanderchlor 200, which is some type of polymer or something and has proven to lower his chlorine addition by -80%, (due to the necessity of keeping a constant vigil on its addition he didn't continue with it). Brice said that this product has both EPA and State Aquatic Toxicity approval; I don't know. He also informed me that this facility is working with an engineer for expansion to 16.0 mgd. We have no notes in the file about such a proposal. I asked him to submit a request for an expansion. 3/25/94 Per discusssion with Mike Alien, facility had sludge permit renewed 8 / 93 [ WQ0001896 ] Staff Report Application indicates chloride, arsenic, cyanide, cadmium, chromium, lead, mercury, copper, iron, nickel, silver, zinc, oil & grease, as well as phenols are in influent. December, 1993 Staff Report indicates facility failed 6 of last 13 Toxicity Tests. During conversation with Russell Brice, (refer above) he informed me that these failures were due to the loss of two basins during construction of their phosphorus removal system. When these basins had to be closed for such construction, the facility lost their nitrification capabilities and that ammonia may have been the reason for the failures. "The RRO would like to note that the discharge [Willow Springs Country Club] is into Contentnea Creek just below Wiggins Mill Dam. This section of the creek has been plagued with frequent fish kills during the summer months. The cause of the fish kills is most likely from the release of very low DO water from the dam, (to meet minimum release requirements), and not from the subject facility." [per Willow Springs Country Club Staff Report] DMR's flow violations early '93; as stated above, facility looking into expansion many BOD and ammonia violations Cyanide limit consistently violated over last three years [ letter from city dated June, '93 indicated cause unknown, but all industries will be monitored for cyanide - January, '94 inspection letter indicates that testing done for nitrate interference and violations still occurred ] Instream Monitoring data indicates pronounced seasonal differences. summer months show significantly depressed DO saturations both up and downstream, (albeit downstream suppression seems to be more pronounced). BOD's were taken in conjunction with these data and also shows significant increases during those periods of low DO saturation.

The application notes that in addition to standard domestic strength waste discharged to the facility, parameters including chloride', cyanide, arsenic", cadmium, chromium; copper, iron, lead, mercury, nickel, silver, zinc, oil and grease, and phenols are also discharged via sanitary sewer. Toxicity results indicate the facility has failed toxicity 6 of the past 13 tests. The Town has recently lost staff in its pretreatment program but is currently training new staff to continue the program that appears to be operated aggressively. RRO staff conducted toxicity sampling during the week of November 2, 1993 and results indicate "pass". The RRO recommends that the permit be reissued in accordance with the basinwide permitting strategy and include the above listed metals with appropriate monitoring/limitations for each.

Sampling 1 - Take a 24-hour composite sample from the final effluent during mid -week (Wednesday through Friday). Collect a grab sample for the volatile organic fraction when collection of the 24-hour composite sample is completed. Follow any other sampling instructions provided by the laboratory performing the analysis. 2 - Indicate in the space provided on Page 1 of 13 this page whether a corresponding sample for toxicity testing was taker 3 - Make note of any unusual wastewater treatment operating conditions occurring on the day of sampling in the space pro- vided on Page 1 of 13. Analysis 4 - Analyze the effluent for pollutants listed on the APAM form, including those to be identified and approximately quan- tified under the 10 significant peaks rule, using appropriate EPA -approved methods for each of the analytic fractions. Other analytical methods can be substituted only with prior, written approval of the Director of the Division of Environs. tat Management (DEM). Read and distribute to the laboratory performing the analysis the accompanying memo (Tedder, Octo. 1990) clarifying analytical requirements. 5 - Identify chemicals to be analyzed for according to the 10 significant peaks rule (as described in item 2 of the Annua Pollutant Analysis Monitoring Requirement in the permit) using a GC/MS library search. Tentative identification s,is all t is required; confirmation by standard injection is not necessary. Estimate the concentration of each based on an internc, standard having the closest retention time. Reporting 6 - Quantitation Limit Targets that should be met are listed on this Revised APAM Reporting Form A. Report the use of any higher quantition limit and an explanation as to why the listed quantitation limit target could not be met. Examples of acceptable reasons for not meeting a quantitation limit target could be high background concentrations in a sample, or tF necessity for sample fraction dilution to bring a chemical to within a quantifiable concentration. List any quantitaticr. limit different (whether higher or lower) from the target in the column provided for the purpose. 7 - If a chemical is found to be below the quantitation limit, report the concentration detected as less than (or '<') the quantitation limit in the appropriate space. Provide a concentration estimate for chemicals detected in concentrations greater than the detection limit and less than the quantitation limit. Enter the detection limit in parentheses beside tr estimate. Chemicals detected in concentrations above the quantitation limits must be quantified. Quantitation limit and detection limit are defined in the NC DEHNR memo (Tedder, October 1990). Enter the total number of peaks detected in each analytic fraction in the appropriate space on this Revised APAM Form A. Report all concentrations in units of micro• grams per liter (ug/L) and metals as total recoverable metal. If no peaks to be identified under the 10 significant peak rule are observed, enter "none" in the space provided for "other" compounds in each appropriate analytic fraction section. Provide the concentration estimate and retention time for "unknowns" as well as for "significant peaks" for which a struc tural assignment can be made. 8 - If "significant peaks" are found, provide ification basis, and MS scan number each. In 9 - In the section labeled "Organic Analytical extraction technique, GC operating conditions, in the appropriate space. probable molecular weight, library match probability, retention time, ident- addition, list internal standards and their retention times. Information", (Page 11 of 13) include for each organic fraction the method, and surrogate recovery. Report the size of the GC/MS library being utilize • 10 - Use copies of this Annual Pollutant Analysis Monitoring Revised Form A to report the results of the analysis. Both the analytical laboratory representative and the facility operator in responsible charge should sign completed forms (last page). 11 - Mail two completed copies of the form (and the laboratory report, if submitted to the facility on a different form) to: ATTN: Central Files, Division of Environmental Management, NC DEHNR, P.O. Box 29535, Raleigh, NC 27626. Mail the APAM form separately from Discharge Monitoring Reports. Page 2 of 13 Y A2. Other Purgeables (up to 10 highest peaks). Compound Probable Molecular Weight Est.

This opportunity eliminated several questions which otherwise could have been encountered in designing a BPR facility based on empirical information, or after conduct of laboratory or pilot plant studies. A plan for the experimental program was developed by Piedmont Olsen Hensley and the study was initiated in May of 1989. Day-to-day operation during the seven month investigation was done by Wilson treatment plant personnel. Operating and laboratory data were compiled in computer spreadsheets and forwarded on disk to the consultant for frequent evaluation of plant performance and guidance about process changes as well as sampling and analytical methods. Pii IsenHensley . The study was not intended to develop fundamental information about BPR, but was designed to provide practical information on the performance that reasonably could be expected of the Wilson plant under various circumstances, using operating staff and support services normally available at that facility. The basic approach • was to run the plant in a series of modes judged to offer promise of providing BPR, with minimal plant configuration changes, without jeopardizing the ability to satisfy effluent discharge standards during the investigation. Each operational mode was designed to evaluate the effects of a specific process change that appeared promising for providing a high degree of removal, without adverse impacts on plant efficiency in other respects. Specific steps in the investigation were planned in general at the beginning, but were modified in response to findings from analyses of data collected as the studies proceeded. The investigation involved four phases of study. Phase 1 was conducted with three tanks in parallel, producing a nominal "complete -mix" :mode of operation. This was essentially the manner in which the plant had been operating successfully for several years, and the principal purpose of this phase was. to establish a baseline of data with which subsequent process modes could be compared. In Phase 2, the plant configuration was changed to place the three aeration tanks in series, a pattern judged to be preferrable for optimizing the BPR processes. There was concern that the series configuration might result in a decrease in BOD removal efficiency. However, data PYedIDontOkenFieruley collected during this phase showed that plant performance was equal to or better than that during Phase 1 for all key parameters specified in the discharge permit.Accordingly, series operation was continued during the rest of the investigation. In Phase 3, aeration was reduced in the first tank in series to induce anaerobic conditions for an improvement in BPR. In Phase 4, the roughing filter was by-passed and aeration was reduced even further. BPR improved significantly, producing 90% removal of phosphorus and an effluent concentration of 0.5 mg/1. It was found that operating the plant under conditions that produced good BPR did not result in any adverse impact on other aspects of plant performance. To the contrary, performance of the system improved slightly during Phase 4 over that experienced in Phase 1. Although the experimental program demonstrated that BPR could be used successfully, it did not provide details on precisely what arrangement of units might be best, or the optimum design parameters for such units. Accordingly, it was decided that the overall design concept should be based on providing flexibility that would permit operation of several different BPR processes, with a wide variety of detention times and loadings that could be adopted within those processes. The process flexibility would facilitate future upgrades in operation that will likely be necessary due to further changes in regulatory requirements, or advances in technology of wastewater treatment. As pointed out earlier, the full-scale studies revealed that BPR improved when the roughing filter was taken out of service and that other performance parameters were not adversely impacted. This led to the conclusion that the roughing filter could better serve plant performance if it were taken out of operation and the structure converted to mixed tankage for anoxic and anaerobic reactions. That would eliminate negative effects on BPR observed in the investigation, as well as providing additional mixed liquor detention time to enhance removal of organics. Pl(senHens(ey Applying the basic concepts outlined above, the plant upgrade was designed to include the following major elements: • The plant headworks and primary settling were un- changed because they were judged to be satisfactory. • The roughing filter was taken out of service, deep- ened, divided into five cells, and converted to mixed anoxic/anaerobic tankage. + Two final clarifiers were added to improve settling ef- ficiency during high wet weather flows. + Effluent polishing ponds were unchanged because they were judged to be satisfactory. . • Extensive changes were made- in piping, valves, instru- mentation, and controls to provide the process flexibility that was desired. 0 .• 6 a tt m L o_ �J C 20-0 rIs Is.c 11.0•05GUIC runs 1. rr.

PiedmontOlsenHensfey Because of a desire to stage construction costs to improve municipal cash flows, design and construction of the new clarifiers was deferred until after start-up of the rest of the modified facilities and initiation of BPR operation. Sludge is stabilized by anaerobic digestion before land disposal. In order to minimize return of phosphorus to the system when exposed to anaerobic conditions, and to maximize digestion time, a belt thickener was installed to increase solids concentration of the waste sludge before discharge into the digester. Operation of the plant upgrade for BPR was started on June 29, 1992. The process selected for initial operation was significantly different from any process reported in the literature. Actually, the specific approach was different even from that contemplated for startup when the design was completed and it is worth noting.that its implemen-tation at the last minute was possible only because of flexibility included in the design. Table 1 summarizes performance 'of the plant during the first six months after startup of the modified BPR system, but before completion of the additional final clarifiers. During this period no chemicals were added for phosphorus removal. The table shows the range in monthly average concentrations of BOD, suspended solids, phos-phorus, TKN, and ammonia nitrogen, as well as the range of data for the maximum day in each month for each para-meter. The plant met NPDES permit limits for all para-meters in Table 1 during each month of the six month period.

Recent reports from plants using BPR processes indicate that the typical removal achieved is about 1.0 mg/1 For the Wilson Plant, the effluent total phosphorus concentration averaged 0.24 mg/1 for the entire period, with monthly averages ranging from 0.20 to 0.29 mg/1. The highest daily effluent phosphorus concentration during the period was 0.57 mg/I. OsenHensley It can be seen that the process used at the Wilson Plant represents an advance in wastewater technology. ]iedmontOlsenHensley
