Accordingly, we are forwarding the attached NPDES discharge permit. This permit 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). Please note that the receiving stream is listed as impaired for benthos on the North Carolina 2014 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required. The following changes were made to the draft permit sent to you on September 9, 2015: • The Terrible Creek WWTP is not receiving any wastewaters from Significant Industrial Users. The Town has maintained a modified Pretreatment Program with a Short Term Monitoring Program that occurs once every five years. As a result, the Town's request to remove effluent conductivity sampling has been granted. In addition, the requirement to monitor conductivity instream has been removed as well. If the Terrible Creek WWTP receives wastewaters from SIU's in the future, this parameter may be added back into the permit. • As requested, the sludge holding tank located off site at Kenneth Branch has been removed from the components list. • In accordance with 15A NCAC 02H .0124, footnote #15 was added to Section A.(3.) stating that reliability measures for facilities with a design capacity equal to or greater than 5 MGD, continuous operation, 24 hours, seven days per week, are required to have. at least one certified operator on each shift, unless the applicant can show the requirement is unwarranted for a particular case. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Toll Free Phone: 877-623-67481 Internet: www.ncdenr.gov An Equal Opportunity I Affirmative Action Employer —Made in part by recycled paper Mr. Chris Grimes, Utilities Operation Director December 4, 2015 Page 2 of 3 As identified previously, the renewal permit contains the following significant changes from your current permit: • The requirement to begin reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to your NPDES permit. [See Special Condition A. (8.)] If the Town is already submitting eDMR's, this requirement should be considered a formality. For information on eDMR, registering for eDMR and obtaining an eDMR user account, please visit the following web page: http:Hportal.ncdenr.org/web/wq/admin/bog/ipu/edmr. For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the following website: hftp://www2.epa.gov/compliance/proposed-npdes-electronic-reporting-rule. i • . Effluent Limitations and Monitoring Requirements for phased tiers 2 MGD and 4 MGD have been removed. Effluent. Limitations and Monitoring Requirements for a 3 MGD interim phase have been added. See Section A.(2.). Effluent limitations and monitoring in Sections A.(2.) and A.(3.) remain the same as in Section A. (1.) except for the ammonia -nitrogen limitations. In accordance with an agreement with EPA Region IV, wasteload allocations for ammonia -nitrogen are based on a summer criterion of 1 mg/L and a winter criterion of 1.8 mg/L. Taking the receiving stream dilution into consideration, the monthly average effluent limits determined for the Terrible Creek WWTP were 1.0 mg/L in the summer (Apr. -Oct.) and 2.0 mg/L in the winter (Nov. -Mar.). These more stringent limitations were contained in the tiered limitations pages in the Terrible Creek WWTP permits' issued in 2000, 2003 and the original Waste Load. Allocation performed in .1990. The more stringent ammonia -nitrogen limitations were placed in the tiered limitations pages for 3 and 6 MGD. Weekly average limits were derived from monthly average limits using a 3:1 ratio. • All samples reviewed since Jan 2013 through June 2015 showed Cyanide at levels less than 5 ug/L. Therefore, Cyanide limitations and monitoring were removed from the permit. A Reasonable Potential Analysis was performed on effluent data for Total Phenolic compounds, Copper and Zinc. No reasonable potential to violate state Water Quality Standards (WQS) was shown for Total Phenolic compounds. Both Copper and Zinc showed reasonable potential to violate WQS; however, Copper and Zinc have action level standards that are applied in conjunction with toxicity test results. Since Terrible Creek WWTP's discharge has passed its overall quarterly toxicity tests during the past five years, no limitations for these parameters were put in the permit. Quarterly sampling for Copper was added to the permit. Zinc sampling was reduced to quarterly to be performed in conjunction with toxicity testing. In accordance with the 2012 Mercury TMDL NPDES Guidance the permittee needs to show annual mean effluent concentrations below both the WQBEL of 12 ng/L and the TBEL of 47 ng/L. Therefore, annual mercury monitoring using EPA approved low-level techniques was added to the permit. • Some of the wording in the Special Condition for Toxicity testing was changed. Please review condition A. (6.) carefully. • Special Condition A.(7.) has been modified to include the three specific years in which the Effluent Pollutant Scans shall be performed (2016, 2017, and 2018). In addition, at the end of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit renewals per Federal Regulations [40 CFR 122.210)(5)] have been added. 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 V Mr. Chris Grimes, Utilities Operation Director December 4, 2015 Page 3 of 3 Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding. Please note that this permit is not transferable except after notice to the Division. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Resources or any other Federal, State, or Local governmental permits that may be required.

Page 8 of 13 Permit NC0066516 SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A. (4.) TOTAL NITROGEN MONITORING a. The Permittee shall calculate monthly and annual TN Loads as follows: i. Monthly TN Load (pounds/month) = TN x TMF x 8.34 where: TN = the average Total Nitrogen concentration (mg/L) of the composite samples collected during the month TMF = the Total Monthly Flow of wastewater discharged during the month (MG/month) 8.34 = conversion factor, from (mg/L x MG) to pounds H.Annual TN Load (pounds/year) = Sum of the 12 Monthly TN Loads for the calendar year b. The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month) in the discharge monitoring report for that month and shall report each year's annual results (pounds/year) in the.December report for that year. A. (5.) ANNUAL LIMITS FOR TOTAL NITROGEN a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River basin are annual limits and are applied for the calendar year. b. For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit in this Permit if: i. the Permittee's annual TN Load is less than or equal to said limit, or ii. the Permittee is a Co-Permittee Member of a compliance association. C. The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in the Permittee's TN allocation. i. Allowable changes include those resulting from purchase of TN allocation from the Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the Permittee and other dischargers; regionalization; and other transactions approved by the Division. ii. The Permittee may request a modification of the TN Load limit in this Permit to reflect allowable changes in its TN allocation. Upon receipt of timely and proper application, the Division will modify the permit as appropriate and in accordance with state and federal program requirements. iii. Changes in TN limits become effective on January 1 of the year following permit modification. The Division must receive application no later than August 31 for changes proposed for the following calendar year. iv. Application shall be sent to: NCDWR/ NPDES Unit Attn: Neuse River Basin Coordinator 1617 Mail Service Center Raleigh, NC 27699-1617 d. If the Permittee is a member and co-Permittee of an approved compliance association, its TN discharge during that year is governed by that association's group NPDES permit and the TN limits therein. i. The Permittee shall be considered a Co-Permittee Member for any given calendar year in which it is identified as such in Appendix A of the association's group NPDES permit. ii. Association roster(s) and members' TN allocations will be updated annually and in accordance with state and federal program requirements. Page 9 of 13 Permit NCO066516 iii. If the Permittee intends to join or leave a compliance association, the Division must be notified of the proposed action in accordance with the procedures defined in the association's NPDES permit. (1) Upon receipt of timely and proper notification, the Division will modify the permit as appropriate and in accordance with state and federal program requirements. (2) Membership changes in a compliance association become effective on January 1 of the year following modification of the association's permit. e. The TN monitoring and reporting requirements in this Permit remain in effect until expiration of this Permit and are not affected by the Permittee's membership in a compliance association. A. (6.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 02B .0200 et seq.] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia duhia at an effluent concentration of 90%. The permit holder shallperform at a minimum, u� artery monitoring using test procedures outlined in the "North Carolina Coiodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be performed during the months of March, June, September, and December. These months signify the first month of each three-month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and 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 -December 2010) 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, DWR Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1623 Mail Service Center Raleigh, NC 27699-1623 Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 Water 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. Assessment of toxicity compliance is based on the toxicity testing quarter, which is the three month time interval that begins on the first day of the month in which toxicity testing is required by this permit and continues until the final day of the third month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. Page 10 of 13 Permit NCO066516 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. A. (7) EFFLUENT POLLUTANT SCAN [G.S. 143-215.1(b)] The Permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below. One scan must be performed in each of the following years: 2016, 2017, and 2018. Analytical methods shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether parameters are present in concentrations greater than applicable standards and criteria.

Page 11 of 13 Permit NCO066516 Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.210) (5). The US EPA requires four (4) toxicity tests for a test organism other than the test species currently requi ed in this permit. The multiple species tests should be conducted either quarterly for a 12-month period prior to submittal of the permit renewal application, or four tests performed at least annually in the four and one half year period prior to the application. These tests shall be performed for acute or chronic toxicity, whichever is specified in this permit. The multiple species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following address: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1623 Mail Service Center Raleigh, North Carolina 27699-1623 Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional toxicity tests and reporting requirements. Results should also be summarized in Part E (Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal application to the NPDES Permitting Unit. A. (8.) . ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [G.S. 143-215.1(b)] Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates that these regulations will be adopted and is beginning implementation in late 2013. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit (Standard Conditions forNPDES Perlvits): • Section B. (11.) 1.

Terrible Creek WWTP currently has a permitted flow of 1.0 MGD and three additional permitted tiers for expansions to 2, 4, and 6 MGD. In October 1999 the facility received an Authorization to Construct (ATC) a 0.5 MGD treatment train which increased capacity to 1 MGD. In July 2015, Jay Meyers, the Public Utilities Director, stated that the Town would like the permit renewal to include a phased expansion from 1 to 3 MGD and then 3 MGD to an ultimate capacity of 6 MGD. He agreed that the effluent sheets for 2 and 4 could be removed. The Town is planning to expand the plant to 3 MGD during 2018. A request for an ATC for the expansion to 3 MGD has not been received at the Division. The existing plant has been reclassified to a Grade fV biological facility achieving nutrient removal. The Town has a contract with McGill to compost waste sludge. The Town has an active pretreatment program, but is not currently accepting flow from any SIUs. As a result, the pretreatment monitoring program is modified such that its Short Term Monitoring Program (STMP) only occurs once every five years for four quarters. There used to be a single metal finishing industry discharging to Terrible Creek; however, that flow has since been diverted to N. Harnett County. Nevertheless, the Town of Fuquay-Varina still oversees the permitting and inspecting of the industry. The Town will continue to monitor every five years in accordance with its established Pretreatment STMP. Terrible Creek is a C-NSW class stream in the Neuse River Basin. The receiving stream is listed on the 2014 303(d) list as impaired for benthos. In addition, the Neuse River estuary to which it drains, is on the 303(d) list for chlorophyll -a. As a result, the upstream waters of the Neuse River Basin have been additionally classified as nutrient sensitive waters (NSW) and the Town of Fuquay-Varina must adhere to the nutrient limitations set out by basin plans and the Nitrogen TMDL. Revised 11/19/2015 Page 1 of 6 Terrible Creek WWTP NCO066516 Nitrogen The Environmental Management Commission adopted Nutrient Management Strategy rules in December 1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters. The point source rule (T15A NCAC 2B .0234) sets Total Nitrogen (TN) discharge limits for all point source dischargers larger than 0.5 MGD. The rule also allows dischargers to form a group compliance association and work together to reduce nitrogen; this option allows the association members added flexibility in controlling nitrogen discharges. At the same time, the association is subject to a group NPDES permit ensuring that the association and its individual members are accountable if they exceed the applicable nitrogen limits. Under the rule, there are three types of TN limit in the Neuse: 1. the individual limits in the dischargers' individual pennits, 2. the aggregate limit in an association's group NPDES pennit, and 3. the individual allocations/limits for each Association member, also in that association permit. A discharger may be subject to the first type of limit or to the second and third, but never to all three at the same time. The discharger is first subject to the TN limit (if any) in its individual NPDES permit. If becomes a co-permittee to a compliance association's group NPDES permit, it is then governed by the TN limits in that permit. If the association complies with its group TN limit in a given year, all members are deemed to be in compliance with their individual allocations/ limits in the group permit. If the association exceeds its limit, the members then become subject to their individual allocations/ limits as well. Regardless of which permit governs a TN discharge, allocations/ limits will likely change over time as the dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations. The Division will modify the affected permits as necessary to ensure that the limits are kept up to date and reflect any such transactions. The permit includes nutrient limits consistent with the Nutrient Management Strategy rule (T15A NCAC 2B .0234). Under the new rule, the Town of Fuquay Varina receives a TN Load limit of 68,489 lb/yr, a calendar year limit. The TN yearly load limit increased from 67,580 lbs to 68,489 lbs as a result of supplemental allocation from Southside MHP (formerly NC0030724) and Wake Technical Institute (formerly NCO025631). In the event the Town joins a compliance association, it will be deemed to be in compliance with the TN limit in this permit, and its TN discharge will be governed instead by the Association's group NPDES permit, issued December 30, 2002. The City's 2.0 mg/L Total Phosphorus limit is carried forward in the new permit as a quarterly average limit to conform with the new rule. Current Effluent Characteristics DMR Data Review The facility's DMR data was reviewed for the period of January 2014 through June 2015. A summary of that data is reported in the following table. The facility is currently discharging at an average of 69% capacity, with maximum monthly average flows at 72 -79% capacity. The facility expects to expand to 3 MGD in the next two years.

The last routine compliance inspection was performed on Jan. 1, 2015. The facility was found to be compliant but the inspection summary recognized that the plant's capacity to handle high flow events continues to be a challenge. As of Aug. 25, 2015, A to C's for the plant expansion or planned upgrades have not been received; however, during a visit to the plant on August 11, 2015, the consultants from Hazen & Sawyer stated that they are currently working on the expansion plans. The last Pretreatment Compliance inspection was performed on Nov. 4, 2014 and the facility was determined to be compliant. Revised 11/19/2015 Page 3 of 6 Terrible Creek WWTP NCO066516 WET Test Results The Terrible Creek WWTP has a chronic whole effluent toxicity testing requirement at 90% effluent concentration. The facility has passed 25/30 tests administered since March 2010. For any failed tests the facility has demonstrated two passes within the following three months. The facility submitted 4 passing toxicity tests using fathead minnow with its application to demonstrate compliance using a second species. Instream Data Review The Terrible Creek WWTP is a member of the Lower Neuse Basin Association (LNBA). There is an LNBA monitoring station 4 miles downstream of the discharge, after the confluence of Terrible Creek and Middle Creek. Reasonable Potential (RP) Analysis and Effluent Pollutant Scans As part of its Modified Pretreatment Program the Town samples for As, Cd, Cr, Cu, CN, Pb, Mo, Ni, Ag, Se, and Zn every five years. Four quarterly samples taken during 2012 showed As, Cd, Cr, CN, Pb, Mo, Ni, Se, and Ag at levels below non -detect. In addition, the facility currently has weekly sampling and limitations for CN. All samples reviewed since Jan 2013 through June 2015 showed CN at levels less than 5 ug/L. Therefore, CN limitations and monitoring were removed from the permit. A reasonable potential analysis was performed on effluent data for Cu, Zn, and Total phenols. No reasonable potential was shown for Total phenolic compounds to exceed the Water Quality Standard of 300 ug/L. Both Cu and Zn showed reasonable potential to violate WQS; however, Cu and Zn have action level standards that are applied in conjunction with toxicity test results. Since Terrible Creek WWTP's discharge has passed its overall quarterly toxicity tests during the past five years, no limitations for these parameters were put in the permit. Quarterly sampling for Cu was added to the permit. Zn sampling was reduced to quarterly to be performed in conjunction with toxicity testing. Ammonia -nitrogen In accordance with an agreement with EPA Region IV, wasteload allocations for ammonia - nitrogen are based on a summer criterion of 1 mg/L and a winter criterion of 1.8 mg/L. Taking the receiving stream dilution into consideration, the monthly average effluent limits determined for the Terrible Creek WWTP were 1.0 mg/L in the summer (Apr. -Oct.) and 2.0 mg/L in the winter (Nov. -Mar.). See WLA attached. These more stringent limitations were contained in the tiered limitations pages in the Terrible Creek WWTP permits' issued in 2000 and 2003. In addition, a letter was sent from DWR to the Town on Jan 10, 1990 stating that the facility design should be based on NPDES permit limitations of 5 (10) mg/L BOD5, 1 (2) mg/L NH3-N, and 6 mg/L dissolved oxygen. This was based on a wasteload allocation performed in 1990. For some reason they were mistakenly changed to 2 mg/L in the summer and 4 mg/L in the winter in the permit issued in 2008. BAT for Ammonia -nitrogen for major municipalities has been defined as 1 mg/L in the summer and 1.8 mg/L in the winter. With these criterion numbers being adopted by EPA and with the expectation that NC will proceed to adopt these criterion during the next Triennial Review the more stringent ammonia -nitrogen limitations were placed in the tiered expansion limitations pages for 3 MGD and 6 MGD. Weekly average ammonia -nitrogen limits were derived from monthly average limits using a 3:1 ratio. The consultants from Hazen & Sawyer and staff at Terrible Creek WWTP were informed of this revision in August 2015 and were asked to consider the more stringent limits in designing the expansion to 3 MGD and 6 MGD. Revised 11/19/2015 Page 4 of 6 Terrible Creek WWTP NCO066516 Mercury TMDL Evaluation All three effluent pollutant scans reported mercury at concentrations less than 200 ng/L. In accordance with the 2012 Mercury TMDL NPDES Guidance the permittee needs to show annual mean effluent concentrations below both the WQBEL of 12 ng/L and the TBEL of 47 ng/L. Therefore, the permittee will be required to monitor mercury annually, using EPA approved low- level techniques.

NAME: TE: Regional Office Comments: RRO arranged a site visit of the WWTP on August 11, 2015. The Region recognizes the need for the facility to expand in order to handle the high flows. RRO recommended renewal of this permit. Addendum: On October 6, 2015 comments were received from Chris Grimes, Utilities Operation Director for the Town of Fuquay-Varina. The following three requests were made and changes made to the permit are italicized. 1) The Terrible Creek WWTP does not receives any wastewaters from SIU's and he asked that monitoring/reporting for conductivity be removed. The Town's request to remove effluent conductivity sampling was granted. In addition, the requirement to monitor conductivity instream was removed as well. If the Terrible Creek WWTP receives wastewaters from SIU's in the future, this parameter may be added back into the permit. 2) The sludge holding tank located off site was removed. The sludge holding tank located off site at Kenneth Branch was removed from the components list. 3) The Town inquired whether there were special staffing requirements for facilities greater than 5 MGD. In accordance with 15A NCAC 02H .0124, footnote #15 was added to Section A.(3.) stating that reliability measures for facilities with a design capacity equal to or greater than 5 MGD, continuous operation, 24 hours, seven days per week, are required to have at least one certified operator on each shift, unless the applicant can show the requirement is unwarranted for a particular case.

I ask that the monitoring/reporting requirement for conductivity be removed. 2) Are there any staffing requirements based on the plants treatment capacity? I have heard that once a plants treatment capacity reaches 5 MGD it must be staffed 24/7. Is that true, and if so can it be mentioned in the renewal permit? 3) Page 2 of 13. Remove the sludge holding tank located off site: Kenneth Branch. Sludge is no longer transported from the Terrible Creek WWTP and stored in the tank at Kenneth Branch. This was done on an emergency basis when the fields were to wet to allow our sludge to be land applied. Wet weather no longer impacts our ability to dispose of our sludge. We contract with McGill and compost our waste sludge. Respectfully Chris E.

I've attached the 2012 data I had in spreadsheet form and the completed pretreatment request. There used to be a single metal finishing industry discharging to Terrible Creek; however, that flow has since been diverted to N. Harnett County. The Town does have an active pretreatment program, but is not currently accepting flow from any SIUs. They do still oversee the permitting and inspecting of the industry. They are sampling for many more parameters than would be required and if requested, could suspend the STMP sampling until they begin accepting wastewater again from a SIU. This request hasn't been made at this time, but the next STMP sampling isn't until 2017. Any questions please let me know. Thanks, Sarah Morrison Bass N.C.
