The WTP treats groundwater from two wells screened in the Castle Hayne aquifer and pumps the finished water into the Town distribution system. The current treatment techniques consist of aeration, filtration, softening, and disinfection. As part of the filtration and softening process, the filter vessels must undergo a backwash process and the softening vessels must undergo a regeneration cycle. The filtration backwash process only utilizes raw water. The softener regeneration cycle also utilizes raw water and a salt (brine) is injected during a small portion of the cycle to restore the softener resin. The wastewater generated by the filtration backwash and softener regeneration is discharged to an unnamed tributary to Mauls Swamp in the Neuse River Basin, under NPDES Permit NC0080071. Due to failed Whole Effluent Toxicity tests (WET), the Town is required by Part A. (3) of the permit to submit a Discharge Alternatives Evaluation with the next permit renewal application. Appendix A contains a copy of the existing discharge permit and the fact sheet for the permit. According to permit requirements, the following options must be evaluated: 1. Connect Discharge to a Wastewater Treatment Plant (WWTP) 2. Obtain a Non -discharge Permit 3. Install Wastewater Treatment 4. Use Alternative Water Treatment Source 5. Use Alternative Water Treatment Method 6. Discharge to a Large Waterbody/Perform a Dilution Model 7. Combination of Alternatives This evaluation is to include a present worth cost analysis for all technically feasible options in accordance with Division of Water Resources guideline "Engineering Alternatives Analysis Guidance Document". M 2.0 1.2 PURPOSE This evaluation is being requested to determine whether there are any economical and technologically feasible alternatives available to the Town to address aquatic toxicity in the plant effluent. Based upon the evaluation, please identify viable alternatives and present an implementation schedule and project timeline for the preferred alternative. The Town shall submit the Discharge Alternatives Evaluation to the Division along with the submission of their next permit renewal application (due 6 months prior to permit expiration). EXISTING CONDITIONS The Town of Vanceboro WTP was designed to receive and treat groundwater pumped from two wells (Well #1 and Well #2). The location of the wells, the WTP, and the NPDES discharge location are shown in Figure 2.1. Information of the two wells supplying the WTP is shown in Table 2.1. Chloride (mg/1) Current Average Daily Pumped Table 2.1 Vanceboro WTP Well #1 7 mg/I (9/11/18) 0.094 MGD Well #2 7 mg/I (9/11/18) 0.094 M G D The average daily demand for the Town varies from 0.176 MGD to 0.218 MGD. This information obtained from monthly operational reports and the 2018 Local Water Supply Plans submitted to NC DEQ Water Supply Section. Appendix B contains a copy of the 2018 Local Water Supply Plan for the Town of Vanceboro. The current treatment train for the Town of Vanceboro WTP is shown in Figure 2.2. The existing treatment techniques utilized at the WTP are as follows (raw to finished): • Aerator • Raw Water Reservoir • High Service Pumps • Filtration • Cation Exchange Softener • Chlorine Gas addition • Discharge of Filter Backwash and Softener Regeneration water to Mauls Swamp There are two existing filter vessels and two existing softeners at the WTP. The filter backwash and softener regeneration cycles occur for every 300,000 gallons of water treated. The cleaning of the filter starts with a filter backwash with a flow rate of 560 gpm for approximately 18 minutes. It is then followed by a filter rinse with a flow rate of 160 gpm for approximately 5 minutes. The regeneration cycle of the softener includes a 10-minute ion exchange backwash with a flow rate of approximately 170 gpm, a 25-minute brine injection with a flow rate of 10 gpm, and a 30-minute ion exchange rinse with a flow rate of approximately 115 gpm. Raw water is used for the filter backwash and softener regeneration cycle. The volume generated during the filter backwash and regeneration cycle are reported on discharge monitoring reports as estimated values because the cleaning processes are completed manually. 2.1 SOURCE WELLS AND WTP DISCHARGE OF REGENERATION WASTE WATER EFFLUENT TO MAULS SWAMP As stated earlier, water generated during the filter backwash and regeneration cycles is currently discharged to Mauls Swamp in accordance with the NPDES permit issued. The discharge location is show in Figure 2.1. Based on discussions with the North Carolina Department of Environmental Quality (NCDEQ) and USGS, Mauls Swamp has no stream gauging station. According to NC DEC, Mauls Swamp has a Class C freshwater classification. Appendix C contains a copy of page 24 of the Neuse River Basin hydro order that documents this classification. Thus, the existing permit does not allow any dilution factor for toxicity testing on the effluent at present. 2.2 DISCHARGE WASTEWATER CHARACTERISTICS The discharge from the filter backwash and softening regeneration process produces a wastewater that is discharged to Mauls Swamp. Data from permit Discharge Monitoring Reports (DMR) from January 2017 to April 2017 were reviewed for flowrate and water quality parameters to determine the character of the discharges. It is important to note that discharge samples are representative samples and thus reflect the filter backwash and regeneration cycle. The routine compliance sampling data indicates that the discharge has TDS, chlorides and conductivity values characteristic of a strong brine. In June 2012, representatives of NC DEQ Washington Regional Office met with the Town to review the WET testing procedures. It was determined that the current procedure for collection of samples were not adequately representing the filter backwash and softener regeneration cycle. A new sampling procedure was created and provided to the Town. Once the plan was implemented, the WET sample tests have since been failures. As part of the Evaluation project, the plan given to the Town was reviewed and determined to be flow volume skewed with regard to the softener regeneration brine cycle. A new plan was developed to address the flow volume discrepancies in the current plan. This updated plan was reviewed by the WaRO staff before implementation. The WET tests after implementation were determined to be failures. Since the WET tests results did not improve, the updated procedures were reviewed and sampling of the regeneration cycle was completed. The sampling determined that the chloride levels associated with the brine cycle injection was detected at the beginning of the rinse cycle and not during the brine cycle. This is due to the low flow volume associated with the brine injection and increased flow rate during the rinse cycle. The sampling was revised to address this new information and data. The plan appears to better address the chloride levels based on when they appear during the softener regeneration cycle. To date however, the Town has not received approval from the WaRO staff for implementation. Based upon existing data from the DMRs, the following data represents current discharges from the WTP: Filter Backwash and Regeneration Volume/Cycle 16,280 gpd Total Chlorides —5,000 mg/L Total Dissolved Solids —20-30 mg/L Salinity —7 ppt Conductivity—5,000-13,000 umhos/cm 2.3 TOXICITY ASSESSMENT Toxicity testing is currently conducted on a composite sample of filter backwash and softener regeneration discharge water. Due to the rating of Mauls Swamp as a zero - flow stream, 90% effluent strength is used in the toxicity testing procedure. Toxicity tests are conducted using Ceriodaphinia dubia (water fleas). The Town has had failures since the representative sampling plan was modified by the WaRO staff. In general, failure of the test occurs due to the chloride levels associated with the regeneration of the softener. 3.o ALTERNATIVES EVALUATION 3.1 Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater treatment plant. Approval or disapproval from the plant operator should be acquired. This alternative would eliminate the surface water discharge by connection to a wastewater treatment plant (WWTP). If a discharge line to the sanitary sewer system were constructed, this line would accept the discharge effluent flows from both the filter backwash and the softener regeneration. The Town of Vanceboro owns and operates a Wastewater Treatment Plant WWTP under Permit Number NC0031828. The WWTP has a permitted capacity of 0.30 MGD and discharges into Swift Creek. Based on discussions with WaRO staff, addition of the discharge from the WTP to the sanitary sewer system may create issues with the WWTP effluent. It is therefore not recommended as a viable alternative. A possible viable option would be the blending of raw water with the WTP discharge prior to entering the sanitary sewer system. This would reduce the chloride concentration in the flow along with other contaminants of concern and not create any issues with regard to permitted capacity at the WWTP. Conversations with WaRO staff have indicated that this would not be a permitted alternative. 3.2 Obtain a Non -discharge permit: Eliminate the surface water discharge by obtaining a non -discharge permit for spray irrigation, infiltration, or subsurface disposal (on -site drain field, infiltration gallery, injection wells). This option eliminates the surface water discharge by obtaining a non -discharge permit for spray irrigation, infiltration, or subsurface disposal. In accordance with the Engineering Alternatives Analysis (EAA) Guidance Document provided by NCDEO' waste streams from ion exchange treatment units do not have to be evaluated for land application. Discharge high in salt concentration is typically not suitable for land application, as excess salts can adversely affect plants via osmotic effect; specific ion toxicity; and soil particle dispersion, which reduces soil permeability and the water infiltration rate. Chloride levels above 350 mg/I and conductivity levels above 3,000 umhos/cm are considered severe potential irrigation problems for land application. Wastewater reuse disposal alternatives include agricultural and landscape irrigation, industrial activities, groundwater recharge, non -potable urban uses (i.e.: toilet flushing, construction water). As explained previously, the waste brine is not suitable for irrigation or landscape irrigation. State of North Carolina code 15A NCAC 02U.1101 prohibits discharge to saltwater wetlands, so this discharge alternative is not available. Additionally, the quality of the discharge would prohibit the use of the discharge for non -potable uses. The brine content does not allow the beneficial use of this waste stream for reuse application. Wastewater reuse is not a feasible alternative for disposal of this discharge. 3.3 Install wastewater treatment: Install improved wastewater treatment to enable the facility effluent to consistently pass the WET test. If this is not technically feasible or cost prohibitive, please explain and provide estimated costs. This alternative requires installation of a wastewater treatment method to enable the facility effluent to consistently pass the WET test. A candidate treatment technology for removal of chlorides is reverse osmosis (RO) technology. However, with such a high chloride content in the feed water, the RO system would need very high pressure and the percent recovery through the process would be 75% or less. Thus, RO process /001� would produce a discharge with a concentrate still requiring discharge to a large water body. There are evaporative type systems that could evaporate the water off the brine wastewater to produce a solid (salt), but they are energy intensive and expensive. Thus, the RO treatment and/or brine evaporation option does not solve the original discharge problem and is not economically feasible. 3.4 Use Alternative Water Treatment Source: Obtain drinking water from another source (nearest County, City, or Town or other wells) so the discharge or toxicity problem is eliminated. This alternative explores the possibility of obtaining drinking water from another source (nearest County, City, or Town or other wells) so the discharge or toxicity problem is eliminated. Based upon the 2018 Local Water Supply Plan, the Town of Vanceboro average daily use ranged from 0.176 to 0.218 MGD and had a maximum day use of 0.3830 MGD (September 2018). The 2018 Local Water Supply Plan also estimated the Town will have a 2060 average daily demand (ADD) of 0.2537 million gallons per day (MGD). Appendix D contains a copy of the Craven County water system Local Water Supply Plan for 2018. The Town of Vanceboro currently has an emergency interconnection with the Craven County water system (NC0425055). Craven County is located within the Central Coastal Plain Capacity Use Area (CCPCUA) and the Craven County water system is a registered permit holder (CU3108). Appendix E contains a copy of the CCPCUA Permit Data for Craven County. Due to the CCPCUA Rules, the Craven County water system has been subject to withdrawal reductions since 2008. The 2018 Local Water Supply Plan indicates that demand as percent of supply is approximately 60% and will approach 80% between 2040 and 2050. At this time, it does not appear that this would be viable alternative source. The Town of Vanceboro utilizes groundwater sources that are in the Castle Hayne aquifer and are currently not subject to withdrawal reductions based on the Central Coastal Capacity Use Area (CCPCUA) Rules. The Division of Water Resources may not permit new groundwater sources located in deeper aquifers that are subject to the CCPCUA Rules. Since there are no public water supply wells located in the deeper aquifers in this area of Craven County, it is not known what raw water quality may exist or what treatment may be required. This alternative would require two new groundwater wells being installed along with the possible construction of a new water treatment plant that would have a discharge. Due to the amount of required infrastructure, this alternative is not financially feasible. 3.5 Use Alternative Water Treatment Method: Install alternative and/or innovative /Ok*� water treatment methods or operational improvements that do not produce toxic wastewaters. For example, install a recycle iron/manganese filtration system with no discharge or combine discharge with WWTP or cooling water effluents. This category includes evaluating alternative and/or innovative water treatment methods or operational improvements that do not produce toxic wastewaters. In effect, this would mean eliminating the softener (and ion exchange) and using a different technology that does not produce the brine/salt discharge in the form of reverse osmosis (110). However, these technologies produce a brine/saline discharge in the form of concentrate stream that must be disposed of. Thus, use of nanofiltration or RO would need to be combined with a large water body discharge to be applicable. This alternative does not solve the original discharge problem and is not economically feasible. 3.6 Discharge to a Larger waterbody/Perform a dilution model: Relocate the facility's discharge to a larger receiving waterbody to eliminate or reduce toxic impacts to the receiving waterbody given the increased dilution. If applicable, perform a dilution model to receive allowance for steam dilution in WET test. In this alternative, the WTP's discharge line would be lengthened and rerouted to a larger receiving waterbody to eliminate or reduce toxic impacts to the receiving waterbody given the increased dilution. For any receiving body, a dilution mixing model effort would be needed to receive allowance for dilution in WET test. A wastewater pump station would be installed at the WTP and the pump station would discharge via a discharge line leading to a single diffuser outlet. The backwash and regeneration cycle volume are produced in approximately 88 minutes. The highest discharge rate during the filter backwash and softener regeneration cycle is 560 gpm. This occurs during the initial segment of the filter backwash. Due to the salty nature of the discharges, the best choice for a new discharge location would be to a tidally influenced area where the salinity of the discharge will not have as great an impact. A larger water body around the Town of Vanceboro is the Neuse River. The Neuse River is located south of the Town of Vanceboro. The advantage to a new discharge into Neuse River segment 27-(96) is that it is classified SC; Sw; NSW. Appendix F contains a copy of page 23 of the Neuse River Basin hydro order that documents this classification. A discharge to SC waters would change the WET test requirements and also chloride limits. A discharge force main from the WTP would be /421'�N approximately 8 miles along Mill Avenue to Hwy 17 Business and then Streets Ferry Road to NC Hwy 55. Appendix G contains a map showing the route required. Due to the amount of required infrastructure, this alternative is not financially feasible. 3.7 Combination of Alternatives: Employ any combination of the alternatives listed above that would result in eliminating or decreasing toxicity until a more feasible solution becomes available. Each of the alternatives stated above either do not solve the original discharge problem and/or are not financially feasible for the Town of Vanceboro. Therefore, a combination of these alternatives would also not solve the original discharge problem and/or would not be financially feasible. 3.8 Discharge Variance The Town of Vanceboro may apply to the Environmental Management Commission (EMC) for a variance to the NPDES permit discharge requirements under State Statute 143-215.3 (e). This statute reads as follows: eoll� "Variances. —Any person subject to the provisions of G.S. 143-215.1 or 143-214.1, 143- 215, or 143-215.107. The Commission may grant such variance, for fixed or indefinite periods after public hearing on due notice, or where it is found that circumstances so require, for a period not to exceed 90 days without prior hearing and notice. Prior to granting a variance here under, the Commission shall find that: (1) The discharge of waste or the emission of air contaminants occurring or proposed to occur do not endanger human health or safety; and (2) Compliance with the rules, standards, or limitations from which variance is sought cannot be achieved by application of best available technology found to be economically reasonable at the time of application for such variances, and would produce hardship without equal or greater benefits to the public, provided that such variances shall be consistent with the provision of the Federal Water Pollution Control Act as amended or the Clean air Act as amended; and provided further, that any person who would otherwise be entitled to a variance or modification under the Federal Water Pollution Control Act as amended or the Clean Air Act as amended shall also be entitled to the same variance from or modification in rules, standards, or limitations established pursuant to G>S> 143-214.1, 143-215, and 143- 215.107, respectively." If NPDES variances were to be granted for the WTPs by the DWR, the variance must be applied for, re-evaluated by DWR, and granted every five years for each NPDES permit renewal. It is /906) not clear at this point what cost would be incurred for the variance requests for the WTP in the future as the requirements are determined on a case by case basis. 4.0 ALTERNATIVES PRESENT WORTH COSTS A present worth costs analysis was not completed because the alternatives would either not solve the original discharge problem and/or would not be financially feasible for the Town of Vanceboro. 5.0 PREFERRED ALTERNATIVE This study has been conducted to meet NPDES permit requirements to assess methods for treatment/discharge of wastewater from the WTP to avoid the toxicity impact on Mauls Swamp. The feasibility of alternative methods was presented in Section 3. The cost of the alternatives is significant and most do not solve the original discharge problem. The Town would prefer to work with NC DEQ Water Resources staff on an updated sampling plan that would assist in securing pass results for the WET tests. This is an alternative that would not add a financial burden to the Town and should meet the goal of regulatory compliance. If this plan of action does not meet the goal of compliance, the next preferred method would be the installation of a holding tank. The tank would have a volume of approximately 20,000 gallons with a mixer to properly combine the filter backwash and softener regeneration prior to discharge. Based on calculations of the chloride loading during the brine cycle compared to the total discharge volume.. WET testing conducted using Ceriodaphinia dubia (water fleas) should provide a pass for chronic test results. 5.1 ALTERNATIVE IMPLEMENTATION It is important to note that the preferred alternative is not part of the seven (7) alternative choices that are listed on page 5 of 7 of the permit. The recommended implementation steps are as follows: 1. Contact NC DEQ Water Resources staff in the Washington Regional Office for a meeting to discuss the representative sampling plan for collection of WET samples from the WTP discharge. tA� 2. Based on the results of the meeting(s), an updated sampling plan may be created for approval of use by the Town of Vanceboro. 3. Conduct WET sampling based on the updated representative sampling plan to determine compliance. 4. If compliance is achieved, no further actions must be taken. 5. If compliance is not achieved, or an updated representative sampling plan cannot be secured, then a meeting with the WaRO staff will be scheduled to discuss the possibility of utilizing a holding tank. After determining what would be required by the State for implementation (i.e. permitting, compliance monitoring, etc.), the Town of Vanceboro would have to review and discuss the financial viability of this alternative. 5.2 PROJECT SCHEDULE The project schedule for implementation steps 1 & 2 are dependent on the availability of the NC DEQ WaRO staff, Town of Vanceboro staff, and consultant. If steps 1 & 2 can be implemented, scheduling of step 3 is strictly based on the WET test compliance monitoring schedule.

The per capita water demand may actually be different than indicated due to seasonal populations and the accuracy of data submitted- Water systems that have calculated longterm per capita water demand based on a methodology that produces different results may submit their information in the notes field. Your long-term water demand is 36 gallons per capita per day. What demand management practices do you plan to implement to reduce the per capita water demand Ileconduct regular water audits, implement a plumbing retrofit program, employ practices such as rainwater harvesting or reclaimed water)? If these practices are covered elsewhere in your plan, indicate where the practices are discussed here. Are there other demand management practices you will implement to reduce your future supply needs? What supplies other than the ones listed in future supplies are being considered to meet yourfuture supply needs?

Must have at I least one data point. The purpose of the above chart is to show a general indication of how the long-term per capita water demand changes over 6me. The per capita water demand may actually be different than indicated due to seasonal populations and the accuracy of data submitted. Water systems that have calculated long-term per capita water demand based on a methodology that produces different results may submit their information in the notes field. Your long-term water demand is 55 gallons per capita per day. What demand management practices do you plan to implement to reduce the per capita water demand (i.e. conduct regular water audits, implement a plumbing retrofit program, employ practices such as rainwater harvesting or reclaimed water)? If these practices are covered elsewhere in your plan, indicate where the practices are discussed here. Are there other demand management practices you will implement to reduce your future supply needs? Continue to promote Water Conservation Education. What supplies other than the ones listed in future supplies are being considered to meet your future supply needs? Our Water Treatment Plant is easily expandable by an additional 2MGD for a total supply of 7-933MGD How does the water system intend to implement the demand management and supply planning components above? Continue to promote Water Conservation by the customer. Carefully monitor the growth of our customer base and plan according to large growth suddenly.
