WOOTEN CORPORATION 185 FORLINES ROAD WINTERVILLE, NORTH CAROLINA MID -ATLANTIC PROJECT NO. OOOR1578.00 Dear Mrs. Lau: 7AUG i 7 zoos i As discussed during our telephone conversation of August 5, 2005, Mid -Atlantic Associates. Inc. (Mid -Atlantic), on behalf of S.T. Wooten Corporation (STW), presents the included supplemental information for the Notice of intent for coverage under North Carolina General Permit 140000. It is our understanding that this supplemental information is sufficient for issuance of the general permit. The requested items are discussed below. A portion of the site map showing the drainage area to the proposed recycling pond is included as Attachment A. As shown, the approximate size of the drainage area is 4.5 acres. The proposed recycling pond will receive runoff from the majority of the plants operations. Runoff from the remaining portion of the site will discharge into a drainage ditch and ultimately off site through an underground pipe located east of the recycling pond. This outfall will receive runoff from an empty field located northeast of the concrete plant along with runoff that contacts portions of the plants material stockpiles. Please note that the topography noted on this map does reiriect actual finishc-d topography at the site. STW is conducting grading operations to facilitate drainage to the recycling pond as outlined by the highlighted drainage area. The hydrograph plot generated by Hydroflow Hydrographs 2004 (Attachment B) indicates that the required storage for the 25-year storm is 7,662 cubic feet. The proposed recycling pond at the site will measure 100' (length) x 30' (width) x 4` (depth) with sides sloped at a 2:1 ratio. The pond will discharge through a 10' weir. The pond report generated by Hydroflow Hydrographs 2004 (Attachment C) indicates that - the total storage capacity of this pond is 16,501 cubic feet, Addendum to Notice of Intent S.T. Wooten Corporation 185 Forlines Road Winterville, North Carolina August 15, 2005 Page 2 • The capacity of the plant is approximately 270 cubic yards per day. STW estimates that approximately five gallons of water is used to wash trucks for each cubic yard of concrete produced. Assuming that approximately 30-gallons of water is used for each cubic yard of -concrete produced; the washwater generated during each business day should be reused in the production process. • The intake for the recycle system will be positioned approximately one -foot from the bottom of the pond. This leaves approximately three feet for storage of stormwater and/or freeboard (Attachment C). • Assuming the water level in the pond is maintained at a depth of one -foot, the remaining storage capacity of the .pond is sufficient to hold the rain from the 25-year storm (7,662 cubic feet) plus over one -foot of freeboard (approximately 5,574 cubic feet). • A pH contingency plan is included in Attachment D. It is our understanding that such a plan needs to be in place in the event the pond were to discharge. To summarize, the recycle system proposed for the subject site is designed such that it will not discharge in response to the 25-year storm. In addition, in the event of a 25 year storm, there should be over one -foot of freeboard in the pond for additional storage. Finally, a pH Contingency Plan will be implemented at the facility. Based on our understanding of the requirements for permitting and .our telephone conversation of August 5, 2005, this information is suffice for predicting compliance with permit limits and facilitating permitting. We appreciate your assistance with this matter. If you have any questions concerning the contents of this letter or need additional information, please do not hesitate to call me at 250- 9918.

PO Box 2408 Wilson, NC 27874-2408 Dear Mr. Washburn, I have enclosed the Engineers Certification of the Model 5000S pH Control System. Please note that several changes have been made insofar as manufacturing and materials used to adjust pH. Initially, Fortrans Inc had a manufacturing agreement with Coastal Carolina Supply wherein Fortrans Inc. was responsible for the marketing of the pH Control Systems and Coastal Carolina Supply was responsible for the manufacturing of the systems. Fortrans Inc. now designs and manufactures the systems. Coastal Carolina has signed a non -compete in the design and manufacture of pH control systems for the ready mixed concrete and related industries. Fortrans Inc. no longer designs systems that use sulfuric acid to lower pH. All of our systems now utilize CO2 feed systems. CO2 is less expensive, safer and readily available to the industry. Regardless of what chemical is used to control pH, the Model 5000S and Model 5000Sk (Skid Mounted) work the same way to monitor and control the pH in settling basins, lagoons, and other containment to effectively control the pH in those areas. I appreciate your comments today relating to our systems performance at your facilities to date and look forward to serving S.T. Wooten Corp. needs in'the future. Please call me if you have any questions or if I may be of service in any way. Sincerely, L Robert C. Cooke, Pres. Fortrans Inc.

Environmental, Inc., was contracted to provide an engineers review and certification that the Model 5000-S pH Monitor and Control System manufactured by Coastal Carolina Supply 'in Morehead City, NC, could effectively provide on a continuous basis, an average pH range of 6-9 units on the supernate layer of a stormwater/rinse water sedimentation basin typically found at Redi- mix concrete facilities. SCOPE OF WORK During theweek of August 11, 2005, G.C. Environmental, Inc_, witnessed'the operation ofthe Model 5000-S self-contained pH Monitoring and Control System at a Redi-mix plant located in Durham, NC. During the two (2) day test program, measurements were made within the facilities stormwater/rinse water sedimentation basin for pH, temperature and depth (both supernate and sludge). 'During the first day of testing, the basin was found to be heavily loaded with solids and adjustments were made to the solids blanket to complete testing the following day. TEST METHODOLOGY A primary sedimentation basin located at a Redi-mix concrete plant located in Durham, NC was treated utilizing the Model 5000-S pH Monitor and Control System. During.the test program, the basin was, on a semi -continuous basis, being fed rinse�water from the exterior cleaning of cement trucks. Measurements for pH, temperature, supernate and sludge blankets were made within the sedimentation basin. Initial pH measurements showed pH levels of at least 12.0 units. The sedimentation basin was rectangular in shape with concrete walls and bottom. The basin ranged in depth of I" at the inlet to approximately 3' at the deepest point. Sludge measurements within the basin showed that at least 2/3 of the basins depth was comprised of sludge and the remainder supernate. The Model 5000-S pH Monitor and Control System was set up at the rectangular sedimentation basin with the intake and discharge hoses situated at opposite ends of the basin. Both the intake and discharge lines were set at depths within the supernate layer of the basin. A clockwise flow pattern was established once the unit began operation and pH and temperature measurements were made at several locations throughout the supernate layer of the sedimentation basin_ Approximately eighteen (19) pH and temperature measurements were collected with a mean pH value of 8.56 and mean temperature values of30.94 CC. The pH system was left to run essentially on a continuous basis over a four (4) hour period_ An estimated volume existing within the sedimentation basin was 25, 000 Im gallons with a little over 8000 gallons consisting of relatively clear supernate. The amount of 25% Sulfuric acid (H^SO,) used to treat the sedimentation basins supernate was approximately 18-20 gallons. MODEL 5000-5 PR MONITOR AND CONTROL, SYSTEM The model 5000-5 pH Monitor and Control System is comprised of a Hayward Power Flow E (3/4 hp, 56 GPM) centrifugal pump which delivers raw water to a completely contained pH sensor connected to a pH meter equipped with control relays which operate two (2) stenner (60 GPD) acid injection pumps. The acid 25% H,SO is injected into the pump discharge line which empties into the sedimentation basin. Sulfuric acid is delivered to the system by 15 gallon carbuoys located outside of the fiberglass weatherproof enclosure which houses all of the aforementioned equipment. On top of the enclosed is an alarm light which is tied into the pH meter which is activated when pH levels exceed 8.5 pH units or are below 6.0 units. CONCLUSION 1. The Model 5000-5 pH Monitor and Control System is an effective system for the pH balancing of sedimentation basins which are used to collect stormwater runoff and rinse water, commonly found at Red -mix concrete plants. 2. During the test program an average pH of 8.54 units was measured in the subject sedimentation basin with a range of 7.95 to 934 measured. I Sludge levels existing within the rectangular sedimentation ranged from 6.0 inches to 2.0 feet. PH values after pH stabilization at the sludge/supernate interface were approximately 12.0 units 4. For this test program, approximately 180 mull of sulfates were added to the sedimentation basin as a result of pH adjustment with 2-41% sulfuric acid. 5. The 5000-5 pHMonitor and Control System is fully automated and provides a pH adjusted waste water which could effectively be reused within the Redi-mix concrete industry.
