(2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 12%. The permit holder shall perform at a minimum, _guarierl monitoring usingtest procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of February, May, August and November. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised - February 1998) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR -1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT -3 (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, accurate, include all supporting chemical /physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. 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 the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Should any test data from this monitoring requirement 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, minimum control organism reproduction, 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.

Definitions 2/Month Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be representative of the wastewater discharged during the sample period, 3/Week Samples are collected three times per week on three separate calendar days. These samples shall be representative of the wastewater discharged during the sample period. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et. seq. Annual Average The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal coliform, the geometric mean of such discharges. Arithmetic Mean The summation of the individual values divided by the number of individual values. Bypass The known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. Calendar Day The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. Calendar Week The period from Sunday through the following Saturday. Calendar Quarter One of the following distinct periods: January through March, April through June, July through September, and October through December. Composite Sample A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically. Composite samples may be obtained by the following methods: (1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow. (2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a constant time interval. Use of this method requires prior approval by the Director. This method may Version 10/29/2010 NPDES Permit Standard Conditions Page 2 of 18 only be used in situations where effluent flow rates vary less than 15 percent. The following restrictions aIso apply: ➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters 9 Influent samples shall not be collected more than once per hour. ➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab samples at intervals of no greater than 20 minutes apart during any 24-hour period. 9 Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent grab samples at least every six hours; there must be a minimum of four samples during a 24- hour sampling period. Continuous flow measurement Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. Daily Discharge The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all grab samples collected during that period. (40 CFR 122.2) Daily Maximum The highest "daily discharge" during the calendar month. Daily Sampling Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week tmless otherwise specified in the permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).

A suggested sequence within each area, where necessary, is included. B. High Rate Primary Treatment Improvements (High Rate Treatment Structure and Chemical Building) The existing primary microscreen building requires demolition prior to the start of construction of the proposed improvements. As part of the preceding Headworks Improvements Project, a dividing wall with isolation gates has been placed between the primary microscreen building and the RBC influent channel. The Contractor may proceed with demolition of the microscreen building in accordance with the specification requirements at any time. 2. The existing 54" recirculation pipe and valve structures between the primary microscreen building and the RBC influent channel shall be isolated by the existing valve at the north end of the microscreen building to allow for piping removal during building demolition. Coordinate with plant staff to close the existing valve and verify the pipe is isolated. Note that the existing 480V ductbank at the edge of the RBC basin shall remain in service at all times. Existing buried utilities around the perimeter of the primary microscreen building shall be located, identified and relocated as required to allow for primary microscreen building demolition. Relocation of the existing filter backwash piping to connect to the flow Diversion Structure (constructed as part of the headworks project) shall be completed prior to the demolition of the primary microscreen building. 4. Following demolition of the existing primary microscreen building, removal of existing subsurface rock is anticipated for construction of the High Rate Primary Treatment facilities. The Contractor shall assume rock will be encountered and schedule the work accordingly. See Division 2 specification requirements for rock removal requirements including blasting plans, pre -blast surveys, and blast monitoring. The improvements associated with the High Rate Primary Treatment facility may be constructed at any time following demolition of the existing primary microscreen building and shall include all specified testing, checkouts, commissioning, training, etc. prior to activation. See Section 11357 for requirements regarding startup and testing of the High Rate Primary Treatment Facility. 6. The Owner will coordinate for purchase and delivery of coagulant, polymer, and Microsand for system startup and performance testing. Contractor shall notify Owner a minimum of 30 days in advance of need for chemicals and microsand to allow sufficient time to order and deliver materials. C.

Installation of the intermediate clarifier sludge piping from the existing piping to the High Rate Primary Treatment system (where it connects to the common pipe with High Rate Primary Treatment Improvements Project Construction Sequence Metropolitan Sewerage District of Buncombe County 01014-2 C 2018 CDM Smith 20176-115429 All Rights Reserved FINAL SPECIFICATIONS -FOR REVIEW PURPOSES ONLY NOT RELEASED FOR CONSTRUCTION -APRIL 2018 filter backwash and sludge blending well) may be done at any time provided that the connection to the gravity thickener system remains in service. The connection and re- routing of the intermediate clarifier sludge flow to the High Rate Treatment System shall not be made until the High Rate Treatment System sludge blend tank and pump station has achieved substantial completion. In addition, at least one discharge pipe from the High Rate waste sludge pump station must be connected to a minimum of one gravity thickener. b. Connection of the proposed 16" sludge discharge piping from the High Rate Primary Treatment system to the two existing gravity thickeners shall be made one at a time, with one gravity thickener in service and available at all times. The first gravity thickener shall be connected no earlier than 15 calendar days from the time of startup of the High Rate Treatment System. Following acceptance of the High Rate Treatment system and associated waste pumping system to the connected gravity thickener, the second gravity thickener may be connected. c. Following completion of connections of the 16" sludge discharge piping to each gravity thickener the remaining buried yard piping and valves between the two gravity thickeners may be demolished and removed as shown on the Drawings. d. Drain piping systems shall be installed, connected and tested prior to backfill or encasement in concrete beneath slabs/structures. D. Solids Handling Building Improvements Improvements in the solids handling building includes the replacement of the two -existing dewatered cake hydraulic piston pumps and associated appurtenances. The replacement of these pumps shall be done one at a time such that one pump is always in service and available. The first pump shall be fully installed, started -up, testing and placed into service before the second pump replacement can begin including a minimum of 7 calendar days of operation. 2. The replacement pumps may be installed at any time once the replacement equipment has been delivered to the site. Provide a minimum of two -week's notice to the Owner of the proposed schedule for beginning the pump replacement work. The work associated with the pump replacement includes piping and valve replacement as well as re-establishing the second point of sludge discharge to the existing incinerator. Some of this work will necessitate the incinerator being taken out of service for a period. The Owner will provide for hauling and landfilling of sludge during these outages. The outages must be scheduled 30 calendar days in advance with the Owner. The Owner will provide hauling and disposal of dewatered cake on two separate occasions for a maximum of 10 calendar days per outage to facilitate the complete replacement, startup and testing of each pump system. New dewatered cake piping shall be installed to the extent possible prior to shutdowns to minimize plant disruptions. E. Electrical and instrumentation work to support the improvements may be installed at any time but must be coordinated with other plant operations to ensure minimal disruption.

Flow Rates and Starting WSEs: Future Peak Flow = 100 MGD (Downstream WSE = 1949.25) — both HRC trains in service Peak Hour Flow = 84 MGD (Downstream WSE = 1946.19) — both HRC trains in service Design Max Month Flow = 40 MGD (Downstream WSE = 1945.58) — one HRC train in service Average Daily Flow = 19 MGD (Downstream WSE = 1945.22) — one HRC train in service Downstream starting WSE of 1949.25 used for Future Peak Flow calculations represents a maximum worst case condition in the RBC channels in the future. This WSE is not specifically tied to any defined flow scenario. Email documentation is provided confirming this. Design Notes: CDM Smith designed the HRC system with upstream and downstream hydraulic constraints by HDR. Hydraulic profile and summary spreadsheet are attached showing constraints. HRC system includes settling tubes designed by Kruger. Kruger estimated head loss through these to be approximately 0.05 ft. This is included in the model. Additional K -value of 3 is included in the settling tank to be conservative, though this effect is negligible. Model comparison to HRC manufacturer calculations use flow rate of 84 MGD rather than 100 MGD. Each HRC train contains 6 launders. This is modeled as a single launder with 1/6 of the total flow through the train (1/12 the total flow). Elevation of HRC weir calculated by adding the Launder Height provided by the manufacturer (2.13 ft) to the invert elevation of the Launder (1951.08) to get a weir invert of 1953.21. 1950.2 1949.25 1949.25 RBC Isolation Gates Starting WSE- RBC RBC Distri bution Basin Channel w", RBCInfluant Channel 1954.38 1952,97 1953.54 1953.55 1953.52 195 3.62 195 3.63 1953,63 195 3.77 Z)N /Ift ALI', Weir TrainIInvEl SettlingTankTrainI M atu ration to Settl i ng Stilling Well Trains 5tilIingBaffleTrainI Maturation Tank Trains Coag toMaturation 1953.17 Weir Inv El 19947.5 WeirTrain I Inv El 19 51.

Subject: RE: Kruger Comments - 60% BCMSD Plans Follow Up Flag: Follow up Flag Status: Flagged Categories: Teal Hi Bryan — thanks again for this information. We are trying to integrate this information into our hydraulic model but not quite getting the same results that had been noted in previously emails. We had a few more questions, pasted below: - Is the loss coefficient of 3 a K-coefficient/factor? Can you explain how this was derived? - In Kruger's loss calculations, what are you applying this loss coefficient (K -factor) to? A closed pipe the diameter of each tube? An open channel meant to represent the clarifier? - Our initial calcs based on what you shared is not getting the same result of %" of loss. Is %" the absolute maximum you would expect at peak flow? - If %" is not the maximum expected do you have an estimate of what that would be? Thanks for your patience and information on this, if there is someone with in Kruger that knows these hydraulics inside and out I can put our hydraulics engineer in touch with them directly to help answer the questions.

Our settling surface area is 443 sq. ft. (24.5'x 18.083'), this equates to 6202 tubes. The modules have a vertical height of 3' 4" and are angled at 60 degrees. Below is a picture of the measurements for the opening of the tube. I have also attached a reference sheet from a previous project in our submittal regarding the lamella tubes and how the packs get placed in the basins. I don't think it will be necessary to modify the model depicting tubes versus plates.

With the coefficient provided as "3" we would need the number and diameter of settling tubes in each tank. Is this something that can be provided?

Do we need to have a different depiction of this work in the model to show tubes vs. plates? If you could provide thoughts on that as well the number, diameter, and length of the tubes that would be helpful...

Based on the low velocity through these, the headloss is probably going to be around a half inch. For the scraper mechanism it would be assumed similar to the mixers. I have also received the weights of the scraper: Scraper Drive and mechanism: 7,800 lbs Scraper Bridge: 3,100 lbs Bryan Fincher Process Group Manager, Kruger VEOLIA WATER TECHNOLOGIES office : +1 919 653-4532 / cell : +1 336 972-3957 / fax : +1 919 677-0082 Kruger / 4001 Weston Pkwy / Cary, NC 27513 / USA bryan.fincher@veolia.com www.veoliawatertech.com On Sun, Nov 5, 2017 at 1:52 PM, Lapsley, Jonathan <LapslevJS@cdmsmith.com> wrote: Hi Bryan — thanks again for sending over the information on the Kruger hydraulic calculations. We looked at this a bit more end of last week and agree that the mixers and draft tube are negligible. We would like to take into account the losses in the settling tank below the launder troughs — specifically the settling tubes and the clarifier mechanism. Would it be possible for Kruger to share a loss coefficient for these components from the model you mentioned below in the immediate future so we can finalize these hydraulics?

We have recently modeled the tubes through CFD to come up with a coefficient for loss and I'm looking into this. In the document should be the launder information.

One of the key ones that I would need to obtain as soon as feasible would be the information on the Kruger Hydraulic calculations. We have all of the physical dimensions of the chambers/compartments from the previous submittals so things we would need would be: Loss parameters for the equipment such as the clarifier mechanisms, mixers, draft tube mixer, etc. Information on the settling tubes and associated loss calculations including any supports that hold up the tube area Launder information — (length, width, slope, invert, notch width and invert and number of notches per launder) If you could provide this information in addition to possibly what else you may have as far as your detailed hydraulic calculations that would be great so that we can double check all of the numbers.

Heating System Design Guide To determine the amount of heaters required for a typical tank heating application, follow these easy steps: 1. Calculate total Tank Surface Area Tank Area = 3.142 x D x (R+H) Where, D = tank diameter R = tank radius H = tank height (or length) 2. Find Basic Heat Loss from Table 1. 3. Find Insulation Correction Factor from Table 2. 4. Find Windage Factor from Table 3. 5. Add 10% for vertical tanks standing on a concrete base - 1.1 multiplier. 6. Add 10% for safety - 1.1 multiplier. 7. Calculate the Total Heat Loss, Multiply steps: 1x2x3x4x5x6 = Total Heat Loss (Heat Required). 8. Select a suitable ELP Heating Panel for the application from the ELP Specifications. 9. Find the ELP Load Factor at the application temperature from the ELP Load Factor Graph. 10. Calculate selected ELP heater wattage at the application temperature. Multiply Load Factor from step 9 by selected ELP wattage. 11. Calculate selected ELP heater wattage due to voltage difference from design. Multiply the heater wattage (step 10) by the corresponding voltage factor from Table 4. 12. Determine the quantity of ELP Heating Panels required. Divide Total Heat Loss/Requirement by the actual ELP wattage. Divide step 7 by step 11. Note: If this result's fraction exceeds 0.1, increase the quantity of ELP Heaters by one (to next higher whole number). Table 1 - Basic Heat Losses (W/sq.ft.)

Tank will be insulted with 2" thick polyurethane foam insulation and is mounted on a concrete base. Heaters will operate on 220VAC. 1. To calculate total Tank Surface Area in sq.ft., multiply the following: Tank Area=3.142 x D x (R+H)=3.142 x 12'x (6'+20')=980sq.ft. where D = 12', R = 6', H = 20' 2. The Basic Heat Loss from Table 1 for Delta T = 100°F, (80°F - (-200F)), and 2" thermal insulation is 3.5watts/sq.ft. 3. The Insulation Correction Factor from Table 2 for Polyurethane thermal insulation is 0.7. 4. The Windage Factor from Table 3 for 25mph wind velocity is 1.12. 5. To add 10% for vertical tanks standing on a concrete base multiply by 1.1. 6. To add 10% for safety - multiply by 1.1. 7. To calculate the Total Heat Loss (Heat Required), multiply steps 1 through 6. 8. For this 220VAC application, an ELP-6 (48" x 18", 550W, 240V) is a suitable choice. 9. To find the ELP Load Factor at 80 OF from the Graph, follow 80°F vertical line up to the graph and then horizontally across to the left and read the value of 0.95. 10. To calculate actual ELP wattage, multiply 550W x 0.95 = 523W. 11. Since the supply voltage is 220VAC while heater design is 240VAC, multiply heater wattage (523W) from step 10 by the corresponding voltage factor 0.84 from Table 4: 523W x 0.84 = 439W. 12. To determine the total quantity of ELP Heating Panels required for this heating system, divide step 7 by step 11: Quantity of ELP Panels = 3254W - 439W = 7.4 Panels. Since the fraction exceeds 0.1, the total quantity of ELP tank heating panels required is 8.

Non-metallic tanks, lined tanks, tanks containing heat sensitive or viscous materials require special considerations. Consult HOTFOIL. 2. Most typical heating applications drawing less than 20 amps of current may be controlled directly by one or two 20amp rated thermostats. Installation: 3. All applications drawing more than 20amps of current, use multi -phase voltage, alarm, or monitoring, etc. require special control equipment - consult HOTFOIL. 4. For tank "heat up" applications - consult HOTFOIL. 5. Hotfoil recommends the use of an override thermostat or controller on all applications. ELP heating panels are quick and easy to install, require no special tools or skills. Heaters are usually installed by banding them to the tank with metal bands or polyester straps. Installation of several ELP heating panels takes only a few minutes. Refer to ELP Installation Instructions for full details.

Updates since the last email: 1. We are not reusing any of the existing building for the HRT system at all. It will all be new. There is some remaining existing structure, use for it is still TBD (ignore for now). 2. The model has been updated for the newest tank dimensions. SWZOOOPM.rvt You can continue the design calculations of the walls and base slabs with these dimensions. a. Use GWL of 1940.2 for the exterior walls. b. The top of base slab elevation at the pump basement (furthest north) is 1931 and the top slab elevation is 1953 (see attached email from Jon Lapsley) c. For the pump basement, ignore the building above and work on just the exterior walls and base slab. 3. 60% internal submittal is July 18t" 4. We don't have the new Geotech report or borings yet. Chennai budget is still —14k. The scope hasn't been amended yet, but will be. Send me markups as you go. I'll start getting sheets, etc created.

At that point, the model uses a fixed grade node to simulate the gravity flow from the high point to the Sludge Blending Tank. The results above show a negative pressure at the fixed grade node, therefore there is sufficient head from the high point to drive the flow to the Sludge Blending Tank at the design flow rate.

Buncombe County MSD, Asheville, NC French Broad WRF February 2015 Executive Summary The ACTIFLO° pilot testing was conducted at the Metropolitan Sewerage District (MSD) of Buncombe County's French Broad River Water Reclamation Facility (WRF) from December 1s' — December 191" 2014. The French Broad WRF currently employs rotating biological contactor (RBC) as their primary biological process, with no primary treatment. In order to extend the life and improve the operation and maintenance of the existing RBC system, MSD in considering the addition of primary clarification at the facility to further reduce the amount of solids entering the RBC system. Additionally, due to a limited amount of space within the existing facility, high rate primary clarification is being considered due to the technologies small footprint. The purpose of the pilot test was for HDR Charlotte and MSD to evaluate the following parameters: ➢ The ACTIFLO System could meet the pilot test goals: 80% removal of influent TSS and produce effluent with Ortho -Phosphorus greater than 1.0 mg/I throughout various flow rate conditions seen by the facility. These various flow rate scenarios of peak, average, and minimal flow tested the ACTIFLO System's ability to perform throughout a range of system retention times from 6 — 18 minutes and hydraulic loading rates (HLR) from 24 gpm/sf — 80 gpm/sf. During the pilot test MSD asked that operations be further optimized to target 70% removal of influent TSS rather than HDR's initial protocol of 80% removal; ➢ To ensure the performance proven proposed ACTIFLO System full scale design of 70 gpm/sf at a peak flow of 80 MGD would fit into the limited amount space within the facility; ➢ To evaluate the annual operating cost of the ACTIFLO System at daily average flow based on the operating conditions and performance during the pilot test. The pilot set up incorporated 3 mm screens to remove debris from the primary influent prior to entering the ACTIFLO pilot unit. The chemical dosing regimen used during the pilot test consisted of dosing aluminum sulfate into the screened primary influent water prior to entering the coagulation tank and dosing anionic flocculent aid polymer (Hydrex 3596) into the maturation tank with the sand return. During the start up of the pilot unit, the system was charged with ballast material of 130 um microsand. Screened raw water and ACTIFLO effluent water was sampled and analyzed throughout the testing protocol's various conditions to determine the removal rates of various parameters: Total cBOD, soluble cBOD, TSS, VSS, TKN, NH3-N, Total Phosphorous, Ortho -Phosphorous, Alkalinity, COD, and soluble COD. Additionally, system sludge samples were collected and analyzed for Total Solids and Total Volatile Solids The ACTIFLO° Process was able to meet the pilot test goals of greater than 70% and 80% removal of primary influent TSS and an produce an effluent Ortho -Phosphorous greater than 1.0 mg/I throughout most of the test scenarios. Table 1 below summarizes the HDR Charlotte pilot test scenarios and the scenarios added by HDR Charlotte, MSD, and Kruger during the pilot test. Table 2 below summarizes the Confidential: The information contained in this document should not be reproduced, distributed, etc. without the express written consent of Kruger, Inc. 3 ACTIFLW Pilot Test Report Buncombe County MSD, Asheville, NC —French Broad WRF Kruger, Inc. February 2015 performance results of each scenario for TSS and Ortho -Phosphorous. The data summary for all scenarios and parameters can be found in Appendix A. ➢ Aluminum Sulfate doses of 20 mg/I — 53 mg/I produced TSS removals of between 79% - 93%, with 20 mg/I being the optimum dose to achieve just over the revised target of 70% removal at a HLR of 80 gpm/sf; ➢ Aluminum Sulfate doses of 10 mg/I — 47 mg/I produced effluent with Ortho -Phosphorus between 4.4 mg/I and 1.1 mg/I, with the optimum dose for TSS removal of 20 mg/I producing an effluent with Ortho -Phosphorous of 4.5 mg/I at a HLR of 80 gpm/sf. ➢ A consistent flocculent aid polymer dose of 1.2 mg/I was dosed throughout the testing scenarios. On the last day of pilot operations, the French Broad WRF's sludge polymer was dosed as the flocculent aid polymer to determine if it would produce effluent quality that met the pilot test goals. A dose of 2.5 mg/I produced TSS removals of 65% and effluent with Ortho -Phosphorous of 2.2 mg/I ; ➢ The full scale 2 x 40 MGD ACTIFLO System will fit into a footprint of less than 4,000 square feet with a SWD of 21'. This footprint will allow the ACTIFLO System to fit into the available space allocated for the high rate primary clarification system at the French Broad WRF; ➢ Treating an average daily flow of 25 MGD to the target performance goals of 70% removal of TSS and effluent with Ortho -Phosphorous greater than 1.0 mg/I, would only require that one of the proposed 40 MGD ACTIFLO System's trains be in operation. Based on one 40 MGD train in operation; dosing 20 mg/I of aluminum sulfate; 1.2 mg/I of flocculent aid polymer; and sand usages of 2 g/m3, the estimated operating cost of the ACTIFLO System for high rate clarification at the French Broad WRF would be $640,000.

Introduction 1.1 ACTIFLO® Process Description The ACTIFLO® process is a high performance and compact clarification system using micro -sand ballasted flocculation and settling. A coagulant is added to the raw water prior to the coagulation tank, where it is mixed for a period of time that depends on the flow rate. The water then overflows into the maturation tank where micro -sand and polymer are added. The micro -sand provides a large contact area and acts as ballast, therefore accelerating the settling of the precipitate. The destabilized suspended solids will bind to the micro -sand particles via polymer bridges. Increased mixing energy from the addition of a draft tube surrounding the maturation mixer continues to enhance coagulation of the newly formed flocculated particles (floc.) Particles agglomerate and grow into high-density floc known as micro -sand ballasted floc. The flocculated particles then flow with the water under the stilling baffle of the maturation tank and up into the last tank, known as the settling tank. In the settling tank the floc settles rapidly to the bottom. The efficiency of settling is further increased by the use of inclined lamella tubes. The sludge/micro-sand mixture collected at the bottom of the settling tank is pumped to hydrocyclones where the sludge is separated from the micro -sand by the centrifugal force of the vortex action. The recovered clean micro -sand is then recycled to the maturation tank and the separated sludge is continuously discharged. The ACTIFLO® process offers a high degree of flexibility. It has a very short start up time and reaches steady state quickly. It also can accommodate high variations in flow rate. Additionally, the use of micro -sand allows the process to handle sudden variations in water quality such as turbidity, color, and/or temperature.

Buncombe County MSD, Asheville, NC French Broad WRF February 2015 1.3 Coagulant Chemical Data The coagulants evaluated during the pilot study were as follows: • Aluminum Sulfate [Al2(SO4)3 *14 HZO) (48 % wt./wt. active, S.G. = 1.33) Coagulant doses were calculated using the above percent activity and specific gravity. All doses are based on weight of product per volume of water treated (dose = mg/L HZO treated). 1.4 Polymer Chemical Data The polymer evaluated during the pilot study is as follows: ** ` • Hydrex 3596 (Dry Polymer—Anionic— Product of CrownAtions) The polymer was dosed as a 0.10% solution using non -potable water (1 gram of dry polymer / 1 liter dilution water). 1.5 Micro -Sand Data The micro -sand utilized during the pilot study was #65 (effective size 134 µm, uniformity coefficient 1.69) manufactured by Manley Brothers of Indiana, Inc. The micro -sand concentration is to be monitored to ensure the designed micro -sand concentration is withheld. The recycle rate is typically designed for a flow rate of 3-8% of the ACTIFLO® process influent; however, this may vary depending on the application. The hydrocyclone splits the influent slurry with 20% returning to the system, called the underflow, and 80% going out as sludge, called the overflow. Sampling is performed using a graduated cylinder (see diagram below) to capture 1 -Liter of underflow from the hydrocyclone apex. The micro -sand should be allowed to settle out in the cylinder for 60 seconds. Once settled, the volume of the sand can be measured.

February 2015 The micro -sand concentration is calculated using the bulk density of the micro -sand (1.77 g/mL), the volume of micro -sand that settled out in the cylinder, and the total sample volume (1 Q. The ACTIFLO® process influent and hydrocyclone influent flow rates are also needed for the calculation. The micro - sand concentration is calculated using the formula below. C = VS �c QR �c X * —1.77— g = VT QJ 100 mL L Where: C - Micro -Sand concentration g/L VT - Total sample volume, L Vs - Volume of the settled micro -sand after 60 -seconds, mL QR - Hydrocyclone flow rate, gpm Q, - Influent flow rate, gpm X - Recycle percentage, % (If 20%, then X = 20) 1.6 Chemical Dose Calculations All chemical dosages are measured by performing draw -downs on calibration columns. A draw -down is the measured volumetric flow rate of the chemical being dosed into the system. Draw -downs (mL/sec) require an accurate measuring cylinder or column and a stopwatch.

Buncombe County MSD, Asheville, NC French Broad WRF February 2015 the chemical is drawn out at the desired pump speed for at least 1 minute (the longer the draw -down the more accurate the result). 1.6.1 Polymer Dose First, the concentration of the batched polymer has to be calculated. This is done on either a mass or volume basis. For example, if the polymer is mixed 3 grams dry polymer per 1 L or 3 mL (emulsion) per 1 L water, then the polymer concentration is 0.3%. In order to calculate the polymer dose the draw -down (mL/min) and influent flow rate (M3 /hr) are needed. The polymer dose rate is calculated using the formula below. XP = C* 1000mg * Qp * 3600 sec g QI hour lm3 1000L Where: Xp - Polymer dose, mg/L C - Concentration of polymer solution, g/L Qp - Polymer feed rate, mL/sec Influent flow rate m3 hr 1.6.2 Coagulant Dose � „v The coagulant dosage takes into account the percent activity and the density of the compound.

Buncombe County MSD, Asheville, NC French Broad WRF February 2015 2.0 ACTIFLO® Pilot Study Background 2.1 Pilot Test Objectives The pilot test results would serve as a guideline for the operations of a potential full-scale high rate clarification ACTIFLO® System. Therefore the operating scenarios set forth by HDR's pilot test protocol dictated the HLR and hydraulic retention times (HRT) mimic the design of the proposed 40 MGD ACTIFLO Train. The Pilot Test Objectives for the ACTIFLO' System were to: • Optimize the doses of aluminum sulfate and anionic flocculent to meet the pilot test goals of 80% TSS removal, later revised to 70% removal of TSS by HDR and MSD, and produce effluent with Ortho -Phosphorous greater than 1 mg/I; • Prove the design parameters of the proposed full scale ACTIFLO System including retention times; hydraulic loading rate; establish coagulant, polymer, and microsand doses to estimate annual operating costs; determine waste volumes and concentrations; and establish a budgetary ACTIFLO System price. 2.2 Sample Location & Analys % As a quick system check throughout the entire pilot test, including optimization and the various test scenarios, screened primary influent and ACTIFLO Pilot Unit's effluent were analyzed online and regular grab samples were analyzed in Kruger's pilot lab for pH, turbidity, Ortho -Phosphorous, Total Phosphorous, and temperature. Additionally, composite samplers were used to sample over the course of one hour during each test scenario. After the 30 minute change and stabilization process, either MSD or Kruger pilot engineers would start the composite samplers. The screened primary influent sampler's suction line was mounted in a collection tank after the 3 mm fine screen. The ACTIFLO Pilot Unit's sampler was mounted in the effluent collection trough. All data found in Appendix A was analyzed by MSD's onsite lab, Pace Analytical.

A submersible pump was installed into basin #1 to provide water to the ACTIFLO Pilot Unit. The pump was connected to a 3 mm drum screen and collection tank to screen out debris from the WRF's primary influent. Another submersible pump was installed into the collection tank to provide screened primary influent to the ACTIFLO° pilot unit. Aluminum Sulfate was dosed into the pilot's influent line on the inside of the pilot unit before entering the coagulation tank. Flocculent aid polymer was dosed into the maturation tank with the underflow of the hydrocyclone/microsand return.

February 2015 3.0 ACTIFLO® Performance during Coagulant and Polymer Optimization The high rate clarification ACTIFLO® System was optimized during the first week of operations to determine the best aluminum sulfate dose (alum) and flocculent polymer dose (Hydrex 3596) for meeting the pilot test goals. Results from this optimization were used to establish a starting point for the various pilot protocol test scenarios. 3.1 Aluminum Sulfate Optimization During the alum optimization, the range of doses tested yielded effluent with pH ranging from 6.7 - 6.9, so it was determined no pH adjustment would be necessary. The range of alum doses were selected based on removing 80% of the turbidity from the screened primary influent and keeping the effluent Ortho - Phosphorous (OP) above 1.0 mg/I while operating at HLRs of 50 and 80 gpm/sf . During the optimization, grab samples were analyzed in the pilot unit's lab using the HACH DR 4000. The optimization results are shown below in Table 6 and Figures 6 & 7.

February 2015 After optimizing the ACTIFLO System, the pilot unit was operated per the protocol test scenarios set by HDR Charlotte and MSD to test the ACTIFLO system's performance throughout the various conditions outlined in Table 8. Additionally, the pilot was operated through a low dose alum curve and the French Broad WRF's sludge dewatering polymer was dosed as the flocculent aid polymer to determine if the system could produce effluent meeting the set goals. Composite samplers were used to take samples over the course of one hour during each test scenario, build a composite for each test. The samples were analyzed for: Total cBOD, soluble cBOD, TSS, VSS, TKN, NH3-N, Total Phosphorous, Ortho - Phosphorous, Alkalinity, COD, and soluble COD. During the testing of each Protocol Test Scenario's flow rate, the pilot unit's was operated, with regard to HLR and HRT, to mimic the design conditions of the proposed full scale 40 MGD ACTIFLO Train. Table 8: Pilot Study Protocol Schedule Test Scenario Abandoned 4.1 Test Scenario #1: Average Design Flow The average flow rate at the French Broad WRF has been determined to be 23 MGD. Test Scenario #1 was to evaluate the ACTIFLO System's performance during this average flow rate while feeding a low dose of alum, a medium dose of alum, and a high dose of alum (Test 1A, 113, 1C). A flow of 23 MGD through the full scale 40 MGD Train would be equal to a HLR of 46 gpm/sf. The alum doses were selected based on the optimization and the 80% target removal of the influent turbidity.

February 2015 Conclusions Over the course of the pilot test, the ACTIFLO System proved to be a viable option for providing high rate clarification at Buncombe County MSD's French Broad WRF by meeting the test goals: Removing a minimum of 70% of the primary influent TSS while dosing 20 mg/I of aluminum sulfate at a HLR of 80 gpm/sf. Also, demonstrating that the ACTIFLO Process could reduce the TSS by more than 70% by increasing the dose of aluminum sulfate, if needed by the WRF; ➢ Producing an effluent with an Ortho -Phosphorus greater than 1.0 mg/I at an aluminum sulfate as low as 10 mg/I at a HLR of 80 gpm/sf. Also, demonstrating that the ACTIFLO Process could reduce the Ortho -Phosphorous to 1.1 mg/I by increasing the dos of aluminum sulfate, if needed by the WRF; ➢ The optimum flocculent aid polymer dose was found to be of 1.2 mg/I and was dosed throughout the testing scenarios. On the last day of pilot operations, the French Broad WRF's sludge polymer was dosed as the flocculent aid polymer to determine if it would produce effluent quality that met the pilot test goals. A dose of 2.5 mg/I produced TSS removals of 65% and effluent with Ortho -Phosphorous of 2.2 mg/I; Confidential: The information contained in this document should not be reproduced, distributed, etc. without the express written consent of Kruger, Inc. 29 Protocol Test (Flow Flow Rise Rate (gpm/ftzj Alum Dose ImglLl Dose of Al (mg/L) Hydrex 7596 Dose (mg1L) otal CBOD (mg/L cluble CBOD [mg/L TSS (mg/L) OP (mg/L) mol of AL dose/mol of P Sludge TSS (mg/L) Sludge TVS (mgjL) linfluentlEffluentl Influent I Effluent linfluentlEffluentl 1A 145 145 145 145 145 245 127 91 174 33 245 245 245 245 245 159 159 159 46 46 46 46 46 80 40 24 56 12 30 30 80 80 80 50 50 50 =C 45 53 SC 40 40 47 47 37 30 33 10 20 30 40 40 40 40 1.92 2.04 2.41 2.27 1.82 1.82 2.13 2.13 1.68 1.36 1.50 0.45 0.91 1.36 1.82 1.82 1.82 1.82 _.2 1.2 1.2 1.2 1.2 1.2 1.2 1.2 1.2 1.1 1.2 1.2 1.2 1.2 1.2 2.5 2 1.5 298 260 216 191 179 169 185 100 914 135 264 197 181 206 50 1 917 76 9 37 8 43 1 33 517 34 6 319 88 6 130 94 6 83 6 76 7 334 76 7 66 6 22 7 31 3 184 40 3 274 23 1 964 105 84 6 82 3 61 26 6 61 7 50 6 27 1 20 8 184 32 6 18 6 12 6 40 6 107 58 2 61 6 43 9 242 224 220 172 188 202 184 194 194 190 227 247 360 194 184 31 47 7 26 6 13 212 24 32 23 2 16 9 49 6 106 43 26 7 36 6 66 2 93 120 2 9 2 3 2 9 2 6 2 2 2 1 2 7 2 4 2 2 4 3 5 6 8 6 9 2 7 3 3 12 11 0 64 0 62 0 96 11 11 0 72 1 2 8 44 4 5 3 1 2 2 2 27 2 6 1 30 1 38 1 17 1 26 1 68 2 08 1 63 146 1 61 1 04 0 87 0 80 0 66 2 98 1 90 3360 3060 2970 4580 2500 1940 3600 4110 6080 7000 4000 3010 2600 2330 3670 1990 1480 2780 3370 4620 6040 3240 A 1C 2DDP,I1' 2A 2B 3A 3B 3C 5A 3hrcomp v03 10 mg.l Alum 20 mg/1 Alum 30 mg/1 Alum 4hr comp ,+11`40 MSD's Polymer 2.5 mg/L clarifl 2.Omg/Lclarifl 1.5 mg/L clarifl Conclusions Over the course of the pilot test, the ACTIFLO System proved to be a viable option for providing high rate clarification at Buncombe County MSD's French Broad WRF by meeting the test goals: Removing a minimum of 70% of the primary influent TSS while dosing 20 mg/I of aluminum sulfate at a HLR of 80 gpm/sf.

February 2015 ➢ Based on a design of a HLR of 70 gpm/sf, which is 12.5% lower than maximum HLR tested during the pilot test, the full scale ACTIFLO System would fit into a footprint of less than 4,000 square feet with a SWD of 21 feet; ➢ Treating an average daily flow of 25 MGD to the target performance goals of 70% removal of TSS of the primary influent TSS and effluent with Ortho -Phosphorous greater than 1.0 mg/I, would only require that only one of the proposed 40 MGD ACTIFLO System's trains be in operation. Based on one 40 MGD train in operation; dosing 20 mg/I of aluminum sulfate; 1.2 mg/I of flocculent aid polymer; and sand usages of 2 g/m3, the estimated operating cost of the ACTIFLO System for high rate clarification at the French Broad WRF would be $640,000. In conclusion, the ACTIFLO Process proved to be a viable high rate clarification option based on the summary of results produced during the pilot test and would meet all the full scale project's objectives while keeping the installation cost and operating costs to a minimum. Additionally, the ACTIFLO Process is a proven wastewater treatment system with numerous installations across the United States and throughout the world.

The thickened solids are pumped to two existing belt filter presses for dewatering. The dewatered cake is conveyed by screw to two piston type dewatered cake pumps which feed the fluidized bed incinerator (FBI) system which is rated at 40 tons per day. The FBI uses natural gas as the primary fuel in the reactor vessel. Exhaust gasses from the incinerator are treated through a multi-venturi scrubber system with quench vessel with final sorbent polymer composite filters for mercury removal prior to discharge of treated exhaust gas to the atmosphere. Ash slurry is dewatered in a clarifier in the solids handling building and the thickened ash pumped to the onsite lagoon. If the FBI is unavailable for use the Gravity Thickeners are used to storage solids periodically until the FBI becomes available or landfilling of dewatered cake is utilized as an alternate disposal avenue during emergency events. Based on historical plant data, typical blended solids characteristics are: Average feed solids to dewatering: 2.8% Average dry solids from dewatering: 21% Average dry tons burned per month: 590 tons/month Average solids burn rate per hour: 1,8151bs/hour MSD has submitted for the required Title V Air Quality permit associated with their sewage sludge incinerator. The final permit has not been issued to date but is under review by the Western North Carolina Regional Air Quality Association. CDM_ Smith® cdmsmith.com
