Sincerely, Lauren Raup-Plummer, Engineer III Division of Water Resources cc: Wilmington Regional Office, Water Quality Regional Operations Section (Electronic Copy) Laserfiche File (Electronic Copy) Mr. Kyle M. Breuer March 30, 2022 Page 2 of 3 A. Cover Letter: 1. Not applicable. B. Application Fee: 1. Not applicable. C. Application (Form WWIS-R 02-21): 1. Within Section III – Flow Information, there are several items that need to be addressed as follows: a. The provided hydraulic capacity determination was based on the treatment capacity. However, the Town of Surf City’s WWTF is not limited by treatment capacity, it is limited by a disposal capacity of 767,800 gallons per day (GPD) based on the available irrigation acreage at the Sarge Martin and Juniper Swamp sites. This is reflected in the existing permit’s facility description and Attachment A which indicate that the annual average flow for the facility is 767,800 GPD. Please recalculate the hydraulic capacity using the as-built disposal capacity. b. The provided flow determination in Section III, Item 3 of 907,772 GPD does not appear to match our NDMR records. Please provide additional information regarding the average flow determination presented in Section III, Item 3. 2. Four structures are listed in Section VI – Open-Atmosphere Structures. Our records indicate that there are six open-atmosphere structures located between the two sites (Sarge Martin and Juniper Swamp). Additionally, it appears that coordinates for the first three list items are the same for all three structures. Please provide information for all six of the open-atmosphere structures, include updated coordinates for each feature, and provide a brief explanation of each structure’s function or any associated naming conventions. 3. Within Section VII – Related Permits, a collection system permit (WQCS00278) is listed as a receiving collection system. Our understanding is that this permit is for the upstream sewer collection system for Town of Surf City. Please clarify the relationship between WQ0000795 and WQCS000278. D. Attachment A – Site Map: 1. No comment. E. Attachment B – Signature Authority Delegation: 1. No comment. F. Attachment C – Flow Reduction: 1. Not applicable. Mr. Kyle M. Breuer March 30, 2022 Page 3 of 3 G. Attachment D – Certificate of Public Convenience and Necessity: 1. Not applicable. H. Attachment E – Operational Agreement: 1. Not applicable. I. Attachment F – Demonstration of Future Wastewater Treatment Capacities: 1. Our preliminary calculations using the last calendar year’s data indicate that the hydraulic capacity is in excess of 80% (and possibly 90%). Pursuant to 15A NCAC 02T .0118, no permits for sewer line extensions shall be issued to wastewater treatment systems owned or operated by municipalities unless they meet the requirements outlined therein. Has an engineering evaluation of the Town of Surf City’s future wastewater treatment, utilization, and disposal needs been performed? Has a timeline for expansion been established? Please address the requirements of 15A NCAC 02T .0118 based on the revised hydraulic capacity from Comment C.1. J. Attachment G – Easement, Encroachment and Lease Agreements: 1. No comment. K. Attachment H - Affiliations: 1. No comment. L. Attachment I – Compliance Schedules 1. It was indicated that the existing permit does not include any compliance schedules; however, our records indicate that the modifications outlined in the permit dated October 3, 2018 have only been partially completed and certified for the mechanical bar screen replacement. Has any additional progress been made regarding the previously permitted modifications? M. Attachment J – Civil Penalties and Outstanding Violations: 1. No comment. N. Attachment K – Industrial Wastewater: 1. Not applicable. O. Attachment L – Setback Waivers: 1. No comment.
