Sullins Governor Director May 10, 2010 Mr. George Strickland S.T. Wooten Corporation 3801 Black Creek Road Wilson, NC ' 27893 Subject: Request for Additional Information Stormwater Project No. SW8 100410 S.T. Wooten Corp. Concrete Plant No. 21 Onslow County Dear Mr. Strickland: Dee Freeman Secretary The Wilmington Regional Office received and accepted a State Stormwater Management Permit Application for S.T. Wooten Corp. Concrete Plant No. 21 on April 8, 2010. A preliminary in- depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Guidelines: a. Stormwater: i. DWQ Stormwater rules as well as the specific language in the stormwater permits clearly limit the use of engineered systems for the treatment of "stormwater runoff". ii. DWQ does not object to a stormwater discharge from the proposed site and will support the NPDES Permit (NCG140000) for stormwater discharges only. b. Wastewater: i. Water Quality Standards applicable to Mill Creek (Class SA waters) prohibit the Division's ability to approve an NPDES discharge for wastewater. ii. The proposed wastewater recycle system will not be permitted for discharge. iii.- A wastewater recycle system will need to be a non -discharging system and will require permitting through the Aquifer Protection Section (APS).

Stormwater i. DA1 (to pond): 157,798sf 1. Includes 57,863sf of offsite drainage. 2. Because the density of the offsite area cannot be controlled through this permit please either: a. Route the offsite drainage around the project, and show the ditch on the plans. b. Consider the potential BUA on the offsite area tgJ_,9 either at 100% density or at full -build out per zoritrig requirements. ii. DA3 (untreated): 78,047sf 1. Includes 11,702sf of BUA that must be treated by a BMP. If it cannot flow to the pond, then a separate BMP must be provided. It cannot flow to the wetlands untreated. b. Wastewater: i. DA2(wastewater system): 13,850sf - 1 - Please integrate the wastewater guidance specified above into this design. 2. Please delineate this drainage area on the drainage area map on Sheet 5. 3. Please show how the wastewater drainage area will be. separated from the stormwater drainage area using a permanent physical barrier to prevent mixing. Please provide a narrative regarding how the permanent physical barrier will be able to separate the wastewater and stormwater. 4. 1 have inserted a picture below of a similar site where a rock barrier was used. This barrier has failed, and is therefore an example of what the Division does not support for such a , barrier. If a physical barrier is not provided, then the entire site will be covered by the NPDES permit. Page 2 of 5 r SW8 100410 Nlay 1.0, 2010 3. Buffer: a. State Stormwater Buffer: The site drains to a UT to Mill Creek (SA; HQW) but is over '/z mile to the named stream. Joanne Steenhuis, 401 staff in Wilmington Region, has made a stream call for the stream to start at the location shown below, and flow along the lot line and under Hwy172. Please show the top of bank on the plans as well as the 50ft buffer measured from TOB. A 50ft buffer is required for new projects. If you intend to claim to be a redevelopment project such that you require only a 30ft buffer, please _. summarize reasons supporting that claim`in your response a !,. provide a copy of the site survey of the built upon area that you refer to rn your narrative. b.

State Stormwater Calculations: a. Peak Flow Predevelopment: Please provide calculations showing tha��this value is 0.7cfs. b. Pond Required Volume: The supplement shows that 8,695cf is required and 10,716cf is provided. The calculations for 1.5" post development show 11,783cf is required. Please correct any discrepancies. c. Average Head: The calculations show that Option 1 yields 2.17ft, and Option 2 yields 3.50ft. The average depth to use to determine the SAIDA should be rounded to the nearest half -foot. However, an average depth of 3.Oft was used in the calculation. Please make the appropriate corrections, d. Table of Elevations: A table of elevations is provided for the main pond for elevations 31.5-36.0 and for the forebay for elevations 33.0-36.0.

Concrete Plant No. 21 Onslow County Dear Mr. Strickland: Dee Freeman Secretary The Wilmington Regional Office received and accepted a State Stormwater Management Permit Application for S.T. Wooten Corp. Concrete Plant No. 21 on April 5, 2010. A preliminary in- depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Guidelines: a. Stormwater: i. DWQ Stormwater rules as well as the specific language in the stormwater permits clearly limit the use of engineered systems for th- treatment of "stormwater runoff'. ii. DWQ does not object to a stormwater discharge from the proposes' site and will support the NPDES Permit (NCG140000) for stormwater discharges only. b. Wastewater: i. Water Quality Standards applicable to Mill Creek (Class SA waters) prohibit the Division's ability to approve an NPDES discharge for wastewater. ii. The proposed wastewater recycle system will not be permitted for discharge. iii. A wastewater recycle system will need to be a non -discharging system and will require permitting through the Aquifer Protection Section (APS). 2. Drainage Areas: There are three areas a. Stormwater i. DA1 (to pond): 157,798sf 1. Includes 57,863sf of offsite drainage. 2. Because the density of the offsite area cannot be controlled through this permit please either: a.

Please show how the wastewater drainage area will be separated from the stormwater drainage area using a permanent physical barrier to prevent mixing. Please provide a narrative regarding how the permanent physical barrier will be able to separate the wastewater and stormwater. 4. 1 have inserted a picture below of a similar s4e where a rock barrier was used. This barrier has failed, and is therefore an example of what the Division does not support for such a barrier. If a physical barrier is not provided, then the entire site will be covered by the NPDES permit. Pace 2 of 4 SW8 ENTER THIS ' April X, 2010 3. State Stormwater Buffer: The site drains to a UT to Mill Creek (SA; HQW) but is over '/z mile to the named stream. - Joanne Steenhuis, 401 staff in Wilmington Region, has made a stream call for the stream to start at the location shown below, and flow along the lot line and urider Hwy172.

Wooten Corporation Concrete Plant No. 21 Sneads Ferry; Onslow County The Wilmington Regional Office received an application for the NCG140000, a USGS map showing site location, a copy of the E&SC Approval letter and a copy of the design plans from Withers & Ravenel, on April 5, 2010, for the S.T. Wooten Corporation for concrete Plant No. 21 in Sneads Ferry, Onslow County. The site is located on Highway 172 and drains to an unnamed tributary to Mill Creek which is- a SA, HQW, PNA water of the State. The Tidal Salt Water Quality Standards (15A NCAC 02B.0221) apply for this receiving stream. 15A NCAC 02B.0221(3)(a) specifically states; Floating solids, settleable solids, or sludge deposits: none attributable to sewage, industrial wastes or other wastes. The plans and specifications propose to divert all wastewater generated in the aggregate materials storage area, admix (concrete additives) containment area, cement silo area and truck washdown area to a wastewater recycle system. The recycle settling basin will be designed for the 24 hour 25 year storm event, or an eight inch rain, The proposed recycle settling basin is designed to discharge wastewater if a storm event producing more than eight inches of rain occurs. The overflow would leave the first cell in the recycle system settling basin and discharge to the ground on the facility where stortwater is collected for treatment in the State Stormwater Pond. The Division of Water Quality has not allowed discharges of wastewater to SA waters of the State given the quality standards applicable to Class SA waters, therefore an NPDES permit for the wastewater recycle system cannot be issued. On March 18, 2010, the president of S.T- Wooten Corporation, their engineer, and consultants, met in the Wilmington Regional Office with the Wilmington Regional Supervisor, Rick Shiver, and 1. The focus of this meeting was to discuss the Division's position concerning a wastewater discharge from a recycle system to the receiving stream and/or the State Stormwater facility. They were advised as follows; • DWQ's stormwater rules, as well as the specific language in the stormwater permits, clearly limit the use of engineered systems to the treatment of "stormwater runoff'. • Water quality standards applicable to Mill Creek (Class SA Waters) prohibit the Division's ability to approve an NPDES discharge for wastewater. • DWQ did not object to a stormwater discharge from the proposed site and would support the NPDES Permit (NCG 140000) for stormwater discharges only. • The proposed wastewater recycle system would not be permitted for discharge to surface waters. • A wastewater recycle system would need to be a non discharging system and would require permitting through the Aquifer Protection Section (APS).

This plan approval shall expire December 34, 2013, if no land disturbing activity has been undertaken, as is required by Title 15A NCAC 4B.0029. 2. The developer is responsible for the control of sediment on -site. If the approved erosion and sedimentation control measures prove insufficient, the developer must take those additional steps necessary to stop sediment from leaving this site. Each sediment storage device must be inspected after each storm event. Maintenance and/or clean out is necessary anytime the device is at 50% capacity_ 4. The developer is responsible for obtaining any and all permits and approvals necessary for the development of this project prior to the commencement of this land disturbing activity. This could include agencies such as the Division of Water Quality's stormwater regulations, their enforcement requirements within Section 401 of the Clean Water Act, the U.S. Army Corps of Engineers, jurisdiction of Section 404 of the Clean Water Act, the Division of Coastal Management's LAMA requirements, the Division of Solid Waste Management's landfill regulations, the Environmental Protection Agency and/or The U.S. Army Corps of Engineers jurisdiction of the Clean Water Act, local County or MunicipalitiesL ordinances, or others that may be required. This approval cannot supersede any other permit or approval; however, in the case of a Cease and Desist Order from the Corps of Engineers, that Order would only apply to wetland areas. All highland would still have to be in compliance with the N.C. Sedimentation Pollution Control Act. 5_ If any area on site falls within the jurisdiction of Section 401 or 404 of the Clean Water Act, the developer is responsible for compliance with the requirements of the Division of Water Quality, the Corps of Engineers and the Environmental Protection Agency (EPA) respectively. Any erosion control measures that fall within jurisdictional wetland areas must be approved by the aforementioned agencies prior to installation. The Land Quality Section must be notified of a relocation of the measures in question to the transition point between the wetlands and the uplands to assure that the migration of sediment will not occur. If that relocation presents a problem or contradicts any requirements of either DWQ, the Corps, or the EPA, it is the responsibility of the developer to inform the Land Quality Section regional office so that an adequate contingency plan can be made to assure sufficient erosion control remains on site. Failure to do so will be considered a violation of this approval. Letter of Approval with Modifications and Performance Reservations Project: S. 1'. Wooten ConCrete Plant - Sneads Ferry January 20, 20tO Page 4 of 4 6. Any borrow material brought onto this site must be from a legally operated mine or other approved source. A single use borrow site or an area to waste material is only permissible if it is operated under the total control of the Financially Responsible person or firm who is developing this site and has been separately permitted and incorporated as part of this plan meeting all the requirements of NC General Statue 74-49(7)f. 7. This permit allows for a land disturbance, as called for on the application plan, not to exceed — 3.4 acres. Exceeding that acreage will be a violation of this permit and would require a revised plan and additional application fee. Any addition in impervious surface, over that already noted on the approved plan, would also require a revised plan to verify the appropriateness of the erosion control measures and stormwater retention measures. 8. The construction detail for the proposed silt fence requires reinforcing wire and steel posts a maximum of eight (8) feet apart. Omission of the reinforcing wire is a construction change that necessitates more posts for support, i.e., the spacing distance needs to be reduced to no greater than six (6) feet apart. 9. Because the sediment basins are shown on the plan as the primary sedimentation and erosion control devices on this project, it is necessary that the basins and it's collection system be installed before any other grading takes place on site. If that proves to be impractical, a revised plan must be submitted and approved that addresses erosion and sediment control needs during the interim period until the basins are fully functioning. 10. A graveled construction entrance must be located at each point of access and egress available to construction vehicles during the grading and construction phases of this project. Access and egress from the project site at a point without a graveled entrance will be considered a violation of this approval. Routine maintenance of the entrances is critical. 11. The North Carolina Sedimentation Pollution Control Act mandates a shortened time frame in which to re-establish vegetative groundcover. Slopes (including cuts, fills, and ditch banks) left exposed will, within 21 calendar days after completion of any phase of grading, be planted or otherwise provided with groundcover sufficient to permanently restrain erosion.

THIS SITE HAS BEEN DETERMINED TO DIRECTLY DRAIN TO SA WATERS AS CLASSIFIED BY NCDWQ. THIS PROJECT ALSO HAS BEEN DETERMINED TO DIRECTLY DRAIN TO PRIMARY NURSERY AREAS (PNA) AS CLASSIFIED BY NC DIVISION OF MARINE FISHERIES. AS INSTRUCTED BY NCDWQ, NO COMMINGLING OF STORMWATER AND WASTEWATER IS PERMITTED AT THIS SITE. IN ADDITION, NO INDUSTRIAL_ WASTEWATER IS PERMITTED TO DISCHARGE FROM OPERATIONS LOCATED ON THIS SITE, A RECYCLE FACILITY HAS BEEN DESIGNED TO CAPTURE THE 25YR-24HR STORM EVENT PLUS TRUCK WASHING USAGE WITHOUT DISCHARGE TO SURFACE WATERS. THIS DESIGN CONSISTS OF ISOLATING THE INDUSTRIAL OPERATIONS FROM THE NON -INDUSTRIAL AREAS. SURFACE STORMWATER/WASTEWATER IS COLLECTED VIA CONCRETE SURFACE FLUMES AND DISCHARGES INTO A SERIES OF CONCRETE CHAMBERS DESIGNED TO SETTLE SEDIMENT AND PROVIDE STORAGE AS REQUIRED TO MEET NCDWQ REQUIREMENTS. RECYCLE/PROCESS WATER FROM THE LAST CHAMBER WILL BE PUMPED OUT AND RE -USED TO IRRIGATE AND HYDRATE AGGREGATE STORAGE AREAS AND RE -USED IN PROCESSED READY MIX CONCRETE.. A SEPARATE STORMWATER PERMIT WILL BE PERMITTED THROUGH NCDWQ FOR THE REMAINDER OF THIS FACILITY.

THOUGH NCDWQ HAS CLASSIFIED THE RECEIVING STREAM AS SA WATERS, 15A NCAC 028 .0301 (i) (1) (B) CLASSIFIES UNNAMED FRESHWATERS DRAINING TO TIDAL SALTWATERS AS "C' WATERS. THIS PROJECT ALSO HAS BEEN DETERMINED TO DIRECTLY DRAIN TO PRIMARY NURSERY AREAS (PNA) AS CLASSIFIED BY NC DIVISION OF MARINE FISHERIES. AS INSTRUCTED BY NCDWQ, NO COMMINGLING OF STORMWATER AND WASTEWATER IS PERMITTED AT THIS SITE. A RECYCLE FACILITY HAS BEEN DESIGNED TO CAPTURE THE 25YR-24HR STORM EVENT PLUS TRUCK WASHING USAGE WITHOUT DISCHARGE TO SURFACE WATERS. THIS DESIGN CONSISTS OF ISOLATING THE INDUSTRIAL OPERATIONS FROM THE NON -INDUSTRIAL AREAS. SURFACE STORMWATER/WASTEWATER IS COLLECTED VIA CONCRETE SURFACE FLUMES AND DISCHARGES INTO A SERIES OF CONCRETE CHAMBERS DESIGNED TO SETTLE SEDIMENT AND PROVIDE STORAGE AS REQUIRED TO MEET NCDWQ REQUIREMENTS. RECYCLE/PROCESS WATER FROM THE LAST CHAMBER WILL BE PUMPED OUT AND RE -USED TO IRRIGATE AND HYDRATE AGGREGATE STORAGE AREAS AND RE -USED IN PPOCESSED READY MIX CONCRETE. A NON --DISCHARGE RECYCLE PERMIT WILL BE SOUGHT FROM NCDENR AQUIFER PROTECTION. A SEPARATE STORMWATER PERMIT WILL BE PERMITTED THROUGH NCDWQ FOR THE REMAINDER OF THIS FACILITY. AN EROSION CONTROL PERMIT HAS BEEN ISSUED FOR THIS FACILITY ON JANUARY 20, 2010 FROM NCDENR DIVISION OF LAND RESOURCES REFERENCES: * SCS TR55 "URBAN HYDROLOGY FOR SMALL WATERSHEDS" WITHERS & RAVED EL ENGINEERS I PLANNERS I SURVEYORS 111 6 eXenan Drive Cary, North Carolina 27511 tel: 919-469-3340 www.withersromel.com License No. C-DB32 3 I I 4 I I I 4` 4( 3; 3( K 4`. ---.-_t------ - ----" � +♦~+ +` 1 L , ` ' �-- ♦ ♦1 \ ^ , ! f' 1 Q �r ' 1 I � ! _ ^ ----------- - ------'" + I -------------^-'--- - ED"- VELOCITY DISSIPATPAD-- SWHTLOCATION #3 W/g FILTERfcABRIC UNDERLINEff --``.
