Breazeale Ave Mount Olive, NC 28365 Subject: State Stormwater Management Permit No. SW8 130516 Handy Mart Highway 53 High Density Commercial Wet Detention Pond Project Onslow County Dear Mr, Pope: Donald van der Vaart Secretary Effective August 1, 2013, the State Stormwater program was transferred from the Division of Water Quality (DWQ) to the Division of Energy, Mineral and Land Resources (DEMLR). All previous references to DWQ will remain in older stormwater permits issued prior to August 1, 2013 until they are modified. Please note that this letter (permit) references DEMLR as the Division responsible for issuance of the permit. The Wilmington Regional Office received a complete, modified State Stormwater Management Permit Application for Handy Mart Highway 53 on May 12, 2015. Staff review of the plans and specifications has determined that the project, as proposed, will comply with the Stormwater Regulations set forth in Session Law 2008-211 and Title 15A NCAC 2H.1000. We are forwarding Permit No. SW8 130516 dated May 14, 2015, for the construction, operation and maintenance of the BMP's and built -upon area associated with the subject project. This permit shall be effective from the date of issuance until June 3, 2021, and shall be subject to the conditions and limitations as specified therein. Please pay special attention to the conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed restrictions, certification of the BMP's, procedures for changes of ownership, transferring the permit, and renewing the permit. Failure to establish an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions, to certify the BMP's, to transfer the permit, or to renew the permit, will result in future compliance problems. The following modifications are included and covered by this permit: 1. An increase in the drainage area and amount of impervious area. The previously approved wet detention pond has been demonstrated to be capable of handling the increased runoff with a slight increase in the orifice diameter (from 1.0" to 1.5"). If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes, and must be filed with the OAH within thirty (30) days of receipt of this permit. You should contact the OAH with all questions regarding the filing fee (if a filing fee is required) and/or the details of the filing process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless such demands are made this permit shall be final and binding. If you have any questions, or need additional information concerning this matter, please contact Christine Hall, at (910) 796-7215.

The final plats for the project will be recorded showing all such required easements, in accordance with the approved plans. 6. The runoff from all built -upon area within the permitted drainage area(s) of this project must be directed into the permitted stormwater control system. Page 2of7 State Stormwater Management Systems Permit No. SW8 130516 A vegetated filter strip is not required for this pond as it has been designed for a 90% total suspended solids removal efficiency.

Highway 53-SW8130516 COPIES DATE NUMBER DESCRIPTION 2 Sets of revised plans 2 Revised Stormwater applications with calculations I Check in the amount of $505.00 &22956711t•—�sc �i�» Stormwater Treatment Narrative Handy Mart Hwy 53 DENR DWQ originally issued SW8 130516 on 6/3/13 allowing construction of a convenience store/gas station (with associated sidewalks and parking) on a 2.51 acres tract located at the intersection of Hwy 53 and NCSR 1130 (Maplehurst Rd.) in Jacksonville Township, Onslow County. The permit required construction of a wet pond sized to accommodate 50,290 sf BUA. The convenience store/gas station and associated pond has NOT yet been constructed. The permittee now wishes to modify the Site Plan for the proposed convenience store/gas station increasing the BUA to 54,064 sf. Therefore a Modification and/or Plan Revision is necessary. The project site is located in the White Oak River basin. Currently, most runoff naturally drains to the northwest towards Blue Creek (SC;NSW — 19-8) and to a roadside DOT Swale. No coastal wetlands are onsite. The site is gently sloped (0.6%-1.5% slopes). The proposed development activities are high density (percent impervious > 24%); therefore, stormwater treatment facilities are required. The attached Stormwater Plan includes a wet detention basin to be located at the Northeastern section of the site. This pond has been designed to meet the Coastal Stormwater Rules, and according to current BMP Manual Specifications. The stormwater pond has been designed with a connected forebay and main pond. Runoff from the new impervious surfaces will be diverted to the forebay of the proposed wet detention basin via a storm drain inlet / underground piping. Treated stormwater will exit the main pond via the outlet structure/18" outlet pipe and out on the natural grade. Development on this site will disturb approximately 2.0 acres — the owners will pursue the Erosion / Sedimentation Control Permitting through the conventional (not express) route. Wastewater is to be collected and treated in a proposed onsite septic system. Water supply is by ONWASA. A turn lane will be required for the entrance on NC 53 ECEUVE FEB 18 2095 Permit Number. �`wyl3r25j1�2 (to be provided by DWQ) Drainage Area Number: Wet Detention Basin Operation and Maintenance Agreement I will keep a maintenance record on this BMP. This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one): ❑ does ® does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ® does not incorporate pretreatment other than a forebay. hnportant maintenance procedures: — Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). — No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. — Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. — If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. — Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected once a-month.1q within 24 hours after every storm event greater than 1.0 inches (or 1.5 it dies Tin a- Q VE Coastal County).
