This permit shall be effective from the date of issuance until rescinded, shall void Permit No. WQ0040915 issued July 3, 2019, and shall be subject to the conditions and limitations as specified therein. This cover letter shall be considered a part of this permit and is therefore incorporated therein by reference. This modification eliminates the previously approved 8-inch gravity sewer as it was converted into a 6- inch service line since it only serves a single structure. The relocated 24-inch gravity sewer length is being reduced from 966 feet to match the installed length of 932 feet. Lastly it incorporates a slope variance for 770 feet of the 24-inch laid at 0.04-0.06% that was approved on October 6, 2020. Please pay particular attention to the following conditions contained within this permit: Special Conditions: Condition 1.1: Pursuant to the variance request received August 19, 2020 from Stewart Engineering, Inc. on behalf of the Cape Fear Public Utility Authority, a variance is granted for the construction and operation of approximately 770 linear feet of replacement 24-inch gravity sewer between existing SSMH-G, MH-02A, MH-0213, MH-02C, MH-02D, and MH- 03 at slopes of 0.04 to 0.06%, as indicated on the provided plans and supporting documents. [15A NCAC 02T .0105(n)] Standard Conditions: Condition 11.1: This permit shall not be automatically transferable; a request must be made and approved.

Persons reporting any of the above occurrences shall file a spill report by completing and submitting Part I of Form CS-SSO (or the most current Division approved form) within five days following first knowledge of the occurrence. This report must outline the actions taken or proposed to be taken to ensure that the problem does not recur. Part II of Form CS-SSO (or the most current Division approved form) can also be completed to show that the SSO was beyond control. [G.S. 143-215.1C(a1)] 6. Construction of the gravity sewers, pump stations, and force mains shall be scheduled so as not to interrupt service by the existing utilities nor result in an overflow or bypass discharge of wastewater to the surface waters of the State. [15A NCAC 02T.0108(b)] 7. Upon completion of construction and prior to operation of these permitted facilities, the completed Engineering Certification form with checklist attached to this permit shall be submitted with the required supporting documents to the address provided on the form. A complete certification is one where the form is fully executed and the supporting documents are provided as applicable. Any wastewater flow made tributary to the wastewater collection system extension prior to completion of this Engineer's Certification shall be considered a violation of the permit and shall subject the Permittee to appropriate enforcement actions. If the permit is issued to a private entity with an Operational Agreement, then a copy of the Articles of Incorporation, Declarations/Covenants/Restrictions, and Bylaws that have been appropriately filed with the applicable County's Register of Deeds office shall be submitted with the certification. A complete certification is one where the form is fully executed and the supporting documents are provided as applicable. Supporting documentation shall include the following: a. One copy of the project construction record drawings (plan & profile views of sewer lines & force mains) of the wastewater collection system extension. Final record drawings should be clear on the plans or in accepted electronic format and are defined as the design drawings that are marked up or annotated with after construction information and show required buffers, separation distances, material changes, etc. b. One copy of the supporting applicable design calculations including pipe and pump sizing, velocity, pump cycle times, and level control settings, pump station buoyancy, wet well storage, surge protection, detention time in the wet well, and force main, ability to flush low points in force mains with a pump cycle, and downstream sewer capacity analysis. If a portable power source or pump is dedicated to multiple stations, an evaluation of all the pump stations' storage capacities and the rotation schedule of the portable power source or pump, include travel timeframes, shall be provided. c. Changes to the project that do not result in non-compliance with this permit, regulations, or the Minimum Design Criteria should be clearly identified on the record drawings, on the certification in the space provided, or in written summary form. Prior to Certification (Final or Partial): Permit modifications are required for any changes resulting in non- compliance with this permit (including pipe length changes of 10% or greater by type & size, increased flow, pump station design capacity design increases of 5% or greater, and increases in the number/type of connections), regulations, or the Minimum Design Criteria. Requested modifications or variances to the Minimum Design Criteria will be reviewed on a case -by -case basis and each on its own merit. Please note that variances to the Minimum Design Criteria should be requested and approved during the permitting process prior to construction. After -construction requests are discouraged by the Division and may not be approved, thus requiring replacement or repair prior to certification & activation.

Gravity sewers installed greater than ten percent below the minimum required slope per the Division's Gravity Sewer Minimum Design Criteria shall not be acceptable and shall not be certified until corrected. If there is an unforeseen obstacle in the field where all viable solutions have been examined, a slope variance can be requested from the Division with firm supporting documentation. This shall be done through a permit modification with fee. Such variance requests will be evaluated on a case -by -case basis. Resolution of such request shall be evident prior to completing and submitting the construction certification. [ 15A NCAC 02T.0105(n)] 9. A copy of the construction record drawings shall be maintained on file by the Permittee for the life of the wastewater collection facilities. [15A NCAC 02T .0116] 10.
