Public Utilities Director Brunswick County PO Box 249 Bolivia, North Carolina 28442-0249 Dear Mr. Pierce: Division of Water Quality Coleen H. Sullins Director November 7, 2011 Subject: NPDES Permit Issuance Permit# NCO086819 NE Brunswick Regional WWTP Brunswick County Dee Freeman Secretary The Division of Water Quality is forwarding herewith the Final NPDES permit for the Northeast Brunswick Regional WWTP. This permit renewal, which incorporates a phased expansion to 3.8 MGD, is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). This Final Permit incorporates the following significant changes from your previous permit: • Supplement to Cover Permit Sheet- delete outdated reference to effluent reuse at Magnolia Greens golf course, which has established its own irrigation system. However, it is expected that the Permittee will continue to seek viable reuse candidates. • Effluent Sheet A(1)- delete outdated fecal coliform language. Add Weekly Average Enterococci bacteria limit of 276/100 m] based on Federal criteria. • Effluent Sheet A(1)- delete total residual chlorine (TRC) language, since facility utilizes UV disinfection. • Add new Effluent Sheet A(2) for proposed Phase 1 expansion to 2.475 MGD, and Effluent Sheet A(3) for proposed Phase 2 expansion to 3.8 MGD. This proposed expansion received a Finding of No Significant Impact (FONSI) on August 16, 2011. • Add more stringent TSS limits of 10 mg/l Monthly Average and 15 mg/1 Weekly Average to reflect requirements for Primary Nursery Area (PNA) designated waters, which fall under High Quality Water requirements (per 15A NCAC 2B.0224). The facility is already capable of treating to reuse standards. • Add more stringent minimum effluent DO limit of 6 mg/l to reflect requirements for PNA/HQW waters per 15A NCAC 2B.0224. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

This monitoring must be conducted in concert with the quarterly toxicity testing. • Add quarterly monitoring for mercury to all Effluent Sheets utilizing analysis by low level mercury Method 1631E. Current analysis by EPA Method 245.1 does not provide proper comparison to water quality standards. • Reduce the Effluent Pollutant Scan.frequency from annually to three times per permit term. This permit specifies that the pollutant scans must be conducted during calendar years 2013, 2014, and 2015, with data reported to the Division by December 31 s' of each designated sampling year. • Please note that there are lower laboratory quantitation levels available for cadmium (PQL = 1 ug/1), nickel (PQL= 2 ug/1), and silver (PQL= 5 ug/1). These lower quantitation levels should be utilized in future NPDES sampling to provide proper comparison to surface water quality standards. • Please note that upon expansion to 3.8 MGD, this facility will be re -rated to a Class 4 WWTP which requires more frequent monitoring and a Class 4 ORC. If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714.

The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24-hour static test. The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure document). Effluent samples for self- monitoring purposes must be obtained during representative effluent discharge below all waste treatment. The tests will be performed during the months of January, April, July and October. 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 TGE6C. Additionally, DWQ Form AT -2 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quality Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. 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 there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited above. 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 the permittee fail to monitor during a month in which toxicity monitoring is required, 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 either these monitoring requirements or tests performed by the North Carolina Division of Water Quality 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 follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

Regarding the RPA's at the expanded flows - Please note that this is a facility discharging to tidal waters so there is no allowance for dilution. Notice the IWC's are 100%. Therefore, the numbers (limits and rpa) will not change with the expanded flows. I have reprinted the RPA at 2.475 and 3.8 MGD and attached all three. Pretreatment Programs - Modified or Full, are not addressed in the NPDES.permit. All aspects of the Pretreatment program are handled separately. If you are looking for NC's definition of a modified program it can be found under 15A NCAC 02H .0904 (b) and is listed below. (b) The Division may allow a control authority having a combined permitted flow less than or equal to two i gallons per day and less than fixe sipi5cant industrial users to &-%vkp and implement a modified pr+etr+e+atment ps that encompasses a portion of the , in Rules .0905 and .0906 of this Section, as designated by the D Directs. In malting the decision to allaw modified prat program development and implemenadon. the D Director may consider fictors including percent industrial flow. i Anuial waste cl~arracoeristics, compliance stamp facility. and the potential for' industrial growth B. 6 and base -neutrals - The table under B.6 appears to be completed. The only parameter not addressed is TRC and this is because the facility uses UV for disinfection, no sampling for TRC is required. A review of the files shows that the City performed four Effluent Pollutant Scans which included volatiles, acids and base -neutrals. Effluent samples were taken on 5-12- 2010, 8-25-2010, 11-10-2010, and 1-5-2011. All four scan results are attached and it confirms that the number of samples is indeed the same as the others. Regarding the additional flow - DWQ does have an approved Engineering Alternatives Analysis (EAA) which specifies their request for a phased expansion from 1.65 to 2.475 to 3.8 MGD. However, I can see in Part B, B.5. d. the expansion from 1.65 MGD to 2.475 MGD is addressed (825,000 GPD expansion) but the additional expansion to 3.8 MGD should have been added. I have a phone call into WK Dickson (City's consultant) and will have them revise the design flow, under A. 6. a. to include the existing flow plus the proposed 2.475 and 3.8 MGD as well as the schedule under B. 5. I would think I could get this simple correction from the City by the end of the week unless you think the EAA is sufficient.(? yes - no) Except for the last item, I believe this addresses all of your concerns. All the attachments are upside down, sorry!. As far as the 90 day extension, I am waiting to hear back from the consultant, is it possible to give me two days to get the revised page with a letter from the City? Please let me know if you have any additional questions on this. Thanks, Julie Julie A.

Cape Fear RB; current Priority Watershed. Tom, I understand from your voice mail that you are on vacation, so I will also address this to Julie just in case she can assist. My comments pertain to the draft permit for NCO086819, N.E. Brunswick Regional WWTP, received 9/19/2011. Julie, The application we received requests renewal of the permit for flow of 1.65 MGD. The fact sheet indicates the facility applied for an expansion and that the proposed expansion was subjected to extended reviews and a positive SEPA/FONZI determination was issued. However, the package sent to Region 4 for review lacks some important data. Title 40, Part 122, Subpart B - Permit Application and Special NPDES Program Requirements requires an application for these additional flow values. If those applications are in house, please forward copies for our files. Also, needed to complete the submitted review package are the reasonable potential analyses (RPA) performed for those expanded flows. They were not included in this package. Data is also missing from the tables for Part B.6. of Form 2A. and Base -Neutral compounds in Part D for the renewal (at 1.65 MGD). It appears that the "Number of Samples" column was intended to extend to the end of the form, but we have no way of confirming that without either your confirmation or copies of the actual data sheets. The fact sheet states that the facility is operating a modified 2 Pretreatment program, but the draft permit does not address a Pretreatment program at all. Can you also forward that part of the draft permit? I realize some of that language is in the recently revised standard conditions, but a "modified" program should include some definitive language to address that. Since Tom is away from the office and these seem to be substantive comments, it may be best to request a 90 -day extension of review for this permit to allow him time to return and address my concerns. Please consider that idea and let me know by C.O.B. today and I will prepare such a letter for your files.

Classification: "Correction Needed on Permit" SC, PNA, HQW b. River Basin and Subbasin No.: 03-06-17; AU # 18-(71)a C. Describe receiving stream features and pertinent downstream uses: Public uses include fishing, boating and crabbing. There are 41 individual NPDES wastewater discharges with a total permitted flow of 99.9 MGD to this segment (49 square miles) of the Cape Fear River with the largest being International Paper (50 MGD, Progress Energy (3.5 MGD), Northside WWTP (16 MGD), and Southside WWTP (12 MGD). d. Aquatic Life Rating: IMPAIRED. There are six aquatic life assessment stations in this segment and all have exceeded the criteria. Each have exceeded low DO and low pH. The stressors for this segment are turbidity, low pH, copper, and low DO. PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. a. Volume of wastewater to be permitted: 1.65, 2.475 MGD in Phase I and 3.8 MGD in Phase Il. b. What is the current permitted flow limit? 1.65 MGD C. Actual treatment capacity of the current facility? 1.65 with both trains operating. This facility does not meet the rules for duality since one oxidation ditch cannot sufficiently treat the entire flow to reliably meet the permitted limitations. No calculations can be found in the region that indicates whether the other treatment processes are capable of treating the entire flow in just one train (clarifier and UV unit). The operator indicated that one train of filters can sufficiently meet TSS limitations in the current permit for the entire permitted flow. Coastal Waste Treatment Disposal rules (15A NCAC 2H.0400) requires all essential treatment and disposal units shall be provided in duplicate. DWQ reviews for future construction must ensure duality criteria is met. d. Date(s) and construction activities allowed by previous Authorizations to Construct issued in the previous two years: N/A e. Please provide a description of existing or substantially constructed wastewater treatment facilities: This plant has BNR capabilities. Existing facilities consist of: 450 KW generator that runs entire facility (with the exception of the maintenance shop); mechanical and manual bar screen; mechanical grit removal; influent flow meter; dual anaerobic selector tanks and dual oxidation ditch with mechanical rotors (2 per reactor); rotary drum thickener with polymer injection system; dual secondary clarifiers; dual tertiary drum filters; dual UV disinfection units (in series); parshall flume for flow monitoring; cascade post aeration; aerated sludge holding (375K gal) tank; and ATAD (50K gal). This plant has no by pass capabilities to any of the treatment units. f. Please provide a description of proposed wastewater treatment facilities: Phase I proposal includes new influent screen, equalization pump station and tank, oxidation ditch, clarifier, effluent filter, UV disinfection, effluent pump, sludge thickener, residuals treatment and 24 inch effluent line to Cape Fear River. The plant has recently received approval (August 16, 2011) for the EA for expansion. g. Possible toxic impacts to surface waters: Potential for pass through from Industrial users. NEB manages a pretreatment program for their SIUs. American Distillation has recently caused an upset by dumping wastewater in exceedance of the SIU permitted limits. h. Pretreatment Program (POTWs only): Yes 2. Residuals handling and utilization/disposal scheme: WQ0019702 reuse permit for 0.325 MGD to Magnolia Greens Golf Course is proposed for elimination since the golf course has implemented its own irrigation system. Land application under WQ0000783 (S&B). 3. The facility has had a good compliance history. 4. "Treatment plant classification: Unchanged (Grade III biological) for 1.65 and 2.475 MGD expansion, however, Grade IV will apply upon completion of the expansion to 3.8 MGD. This permittee is a member of the Lower Cape Fear River Program. Please ensure the permittee notifies DWQ, should they become delinquent in paying their membership dues. SIC Code(s): Unchanged PART III - EVALUATION AND RECOMMENDATIONS PNA, HQW should be added to the classification of the receiving stream for the segment of the Cape Fear River to which this facility discharges (see attached PNA map). Please impose the appropriate TSS limitations since the facility is capable of meeting the lower limit (10 mg/L) and they are required to meet lower limits for the reuse permit. 15A NCAC 9213.0224 (HQW), requires that new or expanded wastewater discharges shall meet effluent limitation for DO of 6 mg/L. The draft permit indicates 5 mg/L, which applies only to SC, not HQW. Please correct this to 6 mg/L for all permit limit pages. The lower Cape Fear River in the vicinity of lock and dam 1 has experienced blue-green algae blooms every summer now for the past several years. Progress Energy's cooling lake intake is near the vicinity of the NEB outfall. Progress Energy has identified the Cape Fear River as the source for their algae bloom issues in Sutton Lake. It would be prudent to include an opener clause in NEB's permit to allow for nutrient limits should the algae blooms pose problems for water quality standards further south in the Cape Fear river. The appropriate monitoring frequencies associated with a Grade IV facility have been imposed in the draft permit for the 3.8 MGD expansion. DWQ needs a mechanism to ensure the Wastewater Certification Unit is notified concerning the change from a Grade III to Grade IV facility upon completion of the 3.8 MGD expansion. DWQ does not have a mechanism (currently) to know whether the members of the LCFRP are paying their yearly dues as required by the MOA. DWQ could support CG&L in their efforts to ensure that any facility that receives state grants or loans, who have proposed reuse as part of their disposal, are held to a detailed compliance schedule defined in their NPDES permits. The compliance schedules could include the requirement to secure any legal contracts necessary to ensure the POTW and their partners follow through with the implementation of reuse. The region is in support of renewal provided the permit is issued with consideration to the concerns provided herein, is issued in accordance with the Cape Fear River Basinwide Plan, and no adverse public comments are received concerning this renew .

Fact Sheet Rmwal -- NPDES Permit NCO086819 Pane I • The proposed phased expansion will include addition of influent screen, equalization tank, aeration basins, clarifiers, effluent filters, UV disinfection, and a 24 -inch effluent discharge line. • The County is expected to construct and operate reclaimed water facilities at the WWTP site. There has been no development of the re -use portion at this time. However, the planned WWTP expansion will be designed to comply with reclaimed water effluent standards at 15A NCAC 2T.0906. RECEIVING STREAM: • The facility discharges treated wastewater via Outfall 001 to the lower Cape Fear River in the Cape Fear River Basin (subbasin 03-06-17, RUC 03030005)). • At the outfall location, the receiving stream is classified SC waters (stream segment 18-(71), which extends from the upstream mouth of Toomer's Creek to a line across the river from Snows Point (through Snows Marsh) to Federal Point). The stream segment also falls within Primary Nursery Area (PNA) waters designated by the Division of Marine Fisheries (DMF), and all PNA waters are also deemed High Quality Water (HQW). • The lower Cape Fear River is listed as impaired on the 2010 303(d) list for copper, low dissolved oxygen, low pH, and turbidity within this stream segment. Much of the low DO condition in the lower Cape Fear River has been attributed to swamp water inputs. • The Permittee is a member of the Lower Cape Fear River Program (LCFRP), which conducts water quality monitoring within the basin to gain a broad water quality perspective. Instream monitoring requirements as part of an NPDES permit are waived as long as the facility maintains membership within the LCFRP. The MOA between DWQ and LCFRP was renewed 7/1/2011. • There is a LCFRP station (B9050025) located within this stream segment. Data for 2006-2010 confirms the low DO condition. FACILITY PERFORMANCE/COMPLIANCE REVIEW: • DMR Data. In 2010, effluent monthly averages ranged as follows: flow (1.0-1.5 MGD), BOD (2-3 mg/1), N113 -N (0.3-1.1 mg/1), TSS (1-2 mg/1), enterococci (1-63 /100ml). The DO Minimum ranged from 6.5-8.5 mg/l. • Permit Violations. Compliance over last permit round has generally been good. Some ammonia violations in Oct/Nov 2008 and Feb/Mar 2009. Facility paid civil penalties totaling $5,130 during this period. • Aquatic Toxicity Testing. The facility has passed all quarterly fathead minnow 24-hour acute toxicity tests (n= 18) at 90% effluent, for period 1/2007 through April 2011. The acute test reflects the tidal nature of the receiving stream. • Compliance Inspections. The facility received "Compliant" ratings for the last Compliance Evaluation Inspection (CEI) conducted 5/12/2010, as well as the last Pretreatment Compliance Inspection (PCI) conducted 8/27/2009. • Compliance Conclusion. There are no significant areas of non-compliance noted over the past permit round. PERMIT LIMIT DEVELOPMENT (Existing Conditions- 1.65 MGD • Maintain limits for BOD and NH3-N at 5&1 mg/1 respectively during summer per Cape Fear Basin Plan. • TSS: Incorporate more stringent TSS limits of 10 mg/l (Monthly Average) and 15 mg/1 (Weekly Average) based on the Primary Nursery Area (PNA) designation, which is subject to more stringent High Quality Water requirements outlined in 15A NCAC 2B.0224. This facility added effluent filters to treat to reuse standards during the last expansion, therefore complying with the more stringent TSS limits should be immediate. • Remove TRC limit/monitoring, since facility utilizes UV disinfection. • Add Weekly Average Enterococci limit of 276/100 ml (geometric mean) based on Federal criteria. Monthly Average limit already exists. Fact Sheet Renewal -- NPDES Permit NCO086819 Page 2 • Maintain pH limits at 6-9 s.u. range. The historical basis for using the freshwater pH range rather than saltwater pH range is to reflect the normal pH conditions of the receiving water. The waters immediately upstream of the discharge are classified C Swamp, and upstream pH values are typically lower due to swamp impact. The pH limit is still consistent with the narrative part of the standard which specifies that the pH should be normal to the waters of the area. • Change Effluent DO limit from 5 mg/1 to 6 mg/l, to reflect HQW requirements per 15A NCAC 2B.0224. • Reasonable Potential Analysis (RPA) for Toxicants: An RPA was conducted to determine need for metals limits. The RPA assumed no dilution due to tidal influence. There was RP for copper and zinc, which are Action Level parameters. Per AL policy, add quarterly monitoring in conjunction with toxicity test. As long as facility is passing toxicity tests, there is no need for permit limits. The receiving stream is also listed as impaired for copper. • Add quarterly mercury effluent monitoring and specify low level mercury analysis (EPA Method 1631 E) to support future mercury TMDL implementation. Historical mercury data was analyzed via Method 245. 1, which only measures down to 200 ng/1. • The current permit is a conjunctive use permit providing for effluent reuse to Magnolia Greens Golf Course. However, the golf course eventually developed their own irrigation water supply and no longer expresses interest in reuse water. Therefore remove permit language on Supplement to Permit Cover Page regarding reuse at golf course. The facility is still expected to pursue reuse options in the future. PERMIT LIMIT DEVELOPMENT (Proposed Phased Expansion to 2.475 MGD/ 3.8 MGD): Water Quality Modeling Results. In response to low dissolved oxygen (DO) concerns in the lower Cape Fear River estuary, the NC DENR funded the development of a three-dimensional water quality model (Environmental Fluid Dynamics Code, or EFDC) by UNC -Charlotte (Bowen et al, 2009). This model was used to investigate the effects of various organic loading reductions; see http://h2o.enr.state.nc.us/tmdl/documents/LCFR DOModelReport Final.pdf. Overall, the EFDC model indicated that the DO deficit caused by sediment oxygen demand (SOD) and upstream river/wetland/swamp loadings are the dominant sources of oxygen demanding wastes to the estuary, as opposed to WWTP loadings. A modeling scenario was specifically conducted for the proposed expansion at Northeast Brunswick Regional WWTP (looking at permitted flows of 1.65 MGD, 4.65 MGD, and 15 MGD, and at BOD/NH3-N concentrations of 5/1 mg/1). Despite the large range in assumed wastewater flows, there were only very small decreases in the predicted DO concentrations (always less than 0.05 mg/1) for summertime conditions in the impaired region. The mean model error was less than 0.01 mg/l. Based on the totality of this model analysis, it appears that the proposed expansion to 3.8 MGD would have an insignificant impact on instream DO. The Division is currently evaluating its DO water quality standard relative to natural background conditions for the lower Cape Fear River, prior to any TMDL development. SEPA/FONSI Determination. The proposed expansion was subject to review by governmental agencies under the State of North Carolina Environmental Policy Act (SEPA EA), and DWQ has concluded that the proposed project will not result in significant impacts to the environment. A Finding of No Significant Impact (FONSI) was issued on August 16, 2011 and is available for inspection at the State Clearinghouse. Antidegradation Review. Per NC Antidegradation Policy (15A NCAC 2B.0201), each applicant for an NPDES permit expansion must document an effort to consider non -discharge alternatives pursuant to 15A NCAC 211.0105(c)(2). This alternatives evaluation was submitted as part of the SEPA EA document, and resubmitted as an Engineering Alternatives Analysis (EAA) for the permit review and modification. DWQ staff reviewed both the flow justification as well as the alternatives analysis. DWQ staff concurred with the projected flow needs based on a 20 -year planning horizon. Rapid growth has occurred in the area between 2000-2009; Leland, Navassa, and Belville (all in the service area) were three top growth municipalities in NC during this time period, and Brunswick County also grew rapidly at greater than 46%. The service area population is projected to increase from 25,102 (in 2010) to 49,877 (in 2030). Likewise, DWQ concurred with the alternatives analysis conclusion that expansion at the current location with a Fact Sheet Renewal -- NPDES Permit N00086819 Page 3 direct discharge to surface water was the most environmentally sound alternative from the reasonably cost-effective options (per 15A NCAC 21-1.0105). A cost evaluation for a non - discharge spray irrigation option for the expanded wastewater volume (2.15 MGD) would require 1,382 acres and a total project cost of $72 Million; in comparison, the total estimated project cost for expanding the current WWTP with direct discharge was estimated at $43 Million, representing a 67% cost savings. The area is known to have soil limitations for onsite septic systems, including presence of a high water table. DWQ concludes that the proposed expansion will provide for public health benefits and social benefit to the community by providing necessary regional wastewater treatment services to accommodate future growth. Proposed Limits/Monitoring. o BOD/NH3-N: Maintain limits of 5/1 mg/l (summer) based on water quality modeling results predicting no change to instream DO at these limits. o TSS: More stringent TSS limits of 10/15 mg/l will be required based on PNA designation, which is subject to more stringent High Quality Water requirements outlined in 15A NCAC 2B.0224. o Dissolved Oxygen (DO): a limit of 6 mg/1 is required based on PNA/HQW requirements stated in 15A NCAC 213.0224. o Enterococci bacteria: Maintain Monthly Average limit of 35/100 ml, and incorporate Weekly Average limit of 276/100 ml. o Copper/Zinc. Based on RP, quarterly monitoring in conjunction with toxicity testing. Both parameters are Action Level standards, which do not require permit limits as long as facility is passing the toxicity test. The receiving waterbody is also listed as impaired for copper. o Nutrients: There are no nutrient limits proposed in this permit, since the receiving waterbody is not listed as NSW and/or 303(d) impaired for chl-a. Nutrient monitoring will continue. SUMMARY OF PROPOSED CHANGES: The Table below summarizes proposed changes for this permit renewal/expansion: Proposed Permit Changes Basis Cover Page.

The e ' ity has had no pollution incidents or compliance issues. The on is needed to accommodate growth in the service area that includes Leland, Navassa, Northwest, Sandy Creek, and Belville. The Phase I expansion is designed in accordance with the NPDES Speculative Limits of May 13, 2009, and comments May 17, 2011, and the reclaimed water regulations NCAC 15A 2T Section .0900. 7 Pro o ro'ec TheLhase 1 �epansion will include new influent screen, equalization pump station and tank, oxi a ion ditch, clarifier, effluent filter, ultraviolet disinfection, effluent pump, sludge thickener, residuals treatment, and 24-inch effluent into the Cape Fear River. The land -disturbing activity associated with the project will consist of clearing and grubbing of vegetation, grading and paving of a new access road, construction of several impoundments, residuals basin, and structures. Construction will also incorporate utilities and sediment and erosion control measures such as temporary sediment traps, silt fence, and gravel construction entrances. The disturbed area for this construction phase is 5 acres. The existing impervious areas on the site total approximately 40,075 square feet and the site was originally permitted under DWQ Permit # SW8 990722. This permit is considered a low density permit with up to 30% built upon area allowed. This phase of the project will add built upon area of 31,500 square feet resulting in a proposed built upon area percentage of 18%. The existing runoff patterns around the existing buildings and structures roughly north to south through sheet flow conveyances and swales. Currently there are two swales that discharge to the roadside ditch along Royster Road. The new access road will have a swale on each side and will drain toward Royster Road and to an existing drainage ditch near the rear of the site. The access road will cross the ditch with dual 48" RCP with headwalls. The project will be funded by the County and the utilities that contribute flow. F.3. Significant Industrial User Information.

Average Daily flow into the Facility for 2010 was 1.34 MGD.The system has complete redundancy in units/ equipment with the exception of the mechanical bar screen, grit removal, rotary drum thickener and ATAD reactor. All flow into the facility is routed thru an influent flow meter then the Headwork's, which consists of a mechanical bar screen and grit removal unit. All flow from these units then proceeds to the anaerobic selector section of the oxidation ditch structure. Here it is mixed with the return activated sludge (RAS) before entering the reactor (aerobic treatment). Level is maintained by a set of mechanical weirs, dissolved oxygen levels are maintained by mechanical rotors (2 per reactor) and rotor immersion thru the programmable logic controllers (PLC) to our SCADA system. At the discharge point of the reactors influent flow is split evenly between our (2) clarifiers. RAS from these 2 units is approx. 70% of incoming flow to the anaerobic selector section for mixing with the incoming waste for further treatment. Waste activated sludge is removed 3 times per week (Approx. 30K gallons per occurrence) thickened by a rotary drum with polymer injection and then batched into our ATAD reactor (50,000 gallon) in 5K -gallon increments. After time/temp. parameters have been met flow is then discharged (5K gallons) to our approx. 375,000 gallon Sludge Holding tank which is mixed by jet aeration prior to land application. Clarifier effluent is combined and routed thru our (2) tertiary effluent filters to the ultraviolet disinfection unit. After disinfection flow is measured in a parshall flume before entering a cascade aeration chamber and ultimate discharge thru our effluent wet well (3 submersible pumps) and discharge to the Cape Fear River. Our current permit is a conjunctive use permit allowing up to .325 MGD to be supplied as re -use water. There has been no development of the re -use portion at this time.
