T Wooten Corporation Burton Park Boulevard, Jacksonville, Onslow County FOR THE construction, operation and maintenance of two (2) wet detention ponds in compliance with the provisions of 15A NCAC 2H .1000 and Session Law 2008-211 (hereafter collectively referred to as the "stormwater rules') the approved stormwater management plans and specifications and other supporting data as attached and on file with and approved by the Division and considered a part of this permit. This permit shall be effective from the date of issuance until May 30, 2021, and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. This stormwater system has been approved for the management of stormwater runoff as described in Section 1.9 of this permit. The stormwater controls labeled BMP #1 and BMP #2 have been designed to handle the runoff from 197,065 and 65,340 square feet of built -upon area, respectively. 3. A 50' wide vegetative buffer must be provided and maintained adjacent surface waters, measured horizontally from and perpendicular to the normal pool of impounded structures, the top of bank of both sides of streams and rivers and the mean high water line of tidal waters. 4. A vegetated filter strip is not required for this pond as it has been designed to provide an average annual total suspended solids removal efficiency of 90%. 5. The level spreaders shown on the plans are not required under the stormwater rules and therefore are not considered a part of the approved state stormwater treatment system. These additional measures are incorporated only by reference and are not enforceable parts of the permit. 6. The tract will be limited to the amount of built -upon area indicated in this permit, and per approved plans. The built -upon area for the future development within the drainage areas of BMP's #1 and #2 is limited to 7,877 and 3,414 square feet, respectively. Page 2 of 8 State Stormwater Management Systems Permit No. SW8 130501 All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements. The final plats for the project will be recorded showing all such required easements, in accordance with the approved plans. 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. The following design criteria have been provided in the wet detention ponds and must be maintained at design condition: Design Criteria BMP #1 BMP #2 a.

The methodology to arrive at the additional volume associated with the truck washing operation is correct, however the minimum required volume for BMP #1 reported in the unsealed, undated, recently received Truck Wash Usage Summary, 14,487 cubic feet, is incorrect. The May 1, 2013 design calculations indicate that the minimum required volume for BMP #1 is 23,550 cubic feet. Additionally, the temporary volume provided, 16,988 cubic feet, is incorrect. The May 1, 2013 calculations (and the permit) indicate that the provided volume in BMP #1 is 25,657 cubic feet. If I add 331 cubic feet to 23,550 cubic feet, the new required minimum volume is 23,881 cubic feet. This is still within the pond design parameters, but you should correct the Truck Wash Water Usage Summary calculations you recently provided to reflect accurate numbers.

From: Lewis,Linda Sent: Friday, August 09, 2013 11:42 AM To: Scott, Georgette Subject: RE: Burton Industrial Park permit The 2475 gallons (331 cf) associated with the truck washing is a daily amount. I think we should account for that daily amount for a total of 5 days. If it doesn't rain for 5 days, during that 5 days, 1,655 cf of volume will have been added to the pond from truck washing. Using that volume, there's still a cushion of 846 cf in the pond, 14487+1655=16142. A total of 16,988 cf has been provided in the pond. If we assume that the minimum volume required and the volume provided in the pond were calculated correctly in the original permit, then everything looks good. I would like to see a condition added to our permit that prohibits truck washing during heavy rain, or when the pond is full and discharging.

Georgette did ask about this when I spoke with her a few weeks ago. I've attached my justification for the design. Essentially, the grading plan resulted in an "extra" 2500 cf of temporary storage in the water quality pool. Based on Wooten's data, and the expected activity in the plant, an average of 330 cf of wash water will be produced. So the wash water will not result in any significant change in the normal water level of the pond, thereby ensuring that there is always sufficient storage for the stromwater. This will, however, result in more frequent small discharges, which will need to be monitored by STW. Hunter From: Pickle, Ken [mailto•ken i)ickle@ncdenr.gov Sent: Friday, August 09, 2013 9:12 AM To: Freeman, Hunter Subject: FW: Burton Industrial Park permit Hi Hunter, Here's a perfectly reasonable request to me from Georgette in Wilmington. As you are aware, we no longer perform and engineering review in the NPDES program for industrial wastewater facilities. However, Georgette's request goes to the sufficiency of the BMP under SW8130501 in the state stormwater management program, the 2H.1000 program. Please forward to me the calcs establishing the sufficiency of that engineered BMP. I mean, please send me the calcs showing that BMP 1 has been designed in accordance with the estimated hydraulic loading including the additional flows from ready -mix concrete operations, as per standard state stormwater design requirements in her program. I'll make a copy for our files, and forward them to her for her files. If there is something I obviously don't understand, please contact me today.

In compliance with the provisions of North Carolina General Statute 143-215.1, other lawful standards and regulations promulgated and adopted by the North Carolina Environmental Management Commission, and the Federal Water Pollution Control Act, as amended, S. T. Wooten Corporation is hereby authorized to discharge to the surface waters of North Carolina from a ready -mix concrete facility located at Burton Industrial Park Concrete Plant 550 Burton Park Boulevard Jacksonville, NC Onslow County to receiving waters designated as an unnamed tributary to New River, a class C, NSW water in the White Oak River Basin.

Wooten will build and configure the facility in substantial conformity with the stormwater and wastewater control systems shown on the Site Plan, Sheet No. 2 of 11, dated and stamped July 2, 2013 by Withers & Ravenel, and submitted with the revised permit application on July 3, 2013. 2. Only wastewater discharges are authorized for Outfall #01, the discharge from BMP 1 as presented on the said Site Plan. Authorized wastewater discharges may arise from truck and equipment washdown activities; from aggregate pile irrigation drainage; and from truck or drum wash out activities. Any other wastewater discharges are not authorized. All flows discharging from Outfall #01 will be regulated as wastewater discharges, -and must comply with the wastewater provisions of NCG140000., 3. Only stormwater-only discharges are authorized for Outfall #02, the discharge from BMP 2 as presented on the said Site Plan. All flows discharging from Outfall #02 will be regulated as stormwater discharges. " 4.
