Box 2408 Wilson, NC 27894 Subject: NOTICE OF VIOLATION Case No. NOV-2005-PC-0174 Review of Stormwater Status at the S.T. Wooten Garner Plant Permit No. NCG140236 Wake County Dear Mr. Washburn: Alan W. Klimek, P.F., Director Division of Water Quality The Division of Water Quality has made three visits to the Garner facility in recent weeks to view and discuss with Wooten personnel the newly constructed stormwater system and its operation. For some time the Division has been communicating to the industry that design of treatment facilities for process wastewater and/or stormwater needs to involve Professional Engineering. The installed system at Garner is a good -faith effort to better handle those waters, and is an improvement in some ways over conditions documented during an inspection in 2002. Unfortunately, there were some errors made that a qualified engineer would have likely avoided. The following issues require consideration and are the reason for this Notice of Violation: The concrete cells were constructed in the 50 ft. buffer zone of a buffered stream in the Neuse River basin. The protected riparian buffer has two zones as follows: (a) Zone 1 [measured from stream bank landward for 30 feet] shall consist of a vegetated area that is undisturbed except for uses provided for in Subparagraph (6) of 15A NCAC 2B.0233, and (b) Zone 2 [the outer 20 feet, landward from the outer 30 foot edge of Zone 1] shall consist of stable vegetated area that is undisturbed except for activities and uses provided for in Subparagraphs (4) and (6) of 15A NCAC 2B.0233. For developed sites (sites with activities/uses located within the buffers prior to 1997), existing uses may continue within the footprint of those uses. No additional impacts to the buffers are allowed. The site visit and file review of this tract confirmed no Pre -Construction Notification was received for this project and riparian buffer impacts associated with clearing of vegetation, grading, filling and addition of impervious surfaces were not authorized by DWQ. Specifically, no request, or a DWQ practical alternative determination, variance or authorization had been issued for these impacts to the riparian zone.

Wooten Garner, 7/2005 Case o. NOV-2005-PC-0174 Based on measurements made at the site, and taking into account the existing pavements that were present prior to construction of the cells and placement of the pipe in the stream (see below), these activities have resulted in 8,100 square feet of Zone 1 impacts. No Zone 2 impacts were noted, as areas within Zone 2were previously paved (existing use). The stream was routed through a culvert for approximately 100 feet from the edge of the driveway to the downstream termination of the pipe. In addition, approximately 30 feet of stream channel beyond the end of the pipe was impacted due to the placement of riprap. A file review indicates that the U.S. Army Corps of Engineers (USACOE) has not authorized the use of a Nationwide Permit for this activity, nor has notification been provided to the Corps of Engineers for this activity. No 401 Water Quality Certification has been issued, nor is the activity covered by a General 401 Water Quality Certification. A 401 Water Quality Certification is required for the above -referenced impacts pursuant to 15A NCAC 2H .0500. There are two options for addressing these violations. a) the structure and culvert pipe can be removed, and the riparian buffer can be restored to it's pre -impact condition, or b) apply for a Major Variance to the buffer rules. A Major Variance request must be approved by the NC Environmental Management Commission, and you must have a very strong case of having no practical alternatives. You will be required to mitigate for buffer impacted by the project. Mitigation costs for Zone 1 impacts are S0.96/square foot of impact x 3. Mitigation payment is made to the N.C. Ecosystem Enhancement Program. In addition to the Major Variance, if you wish to keep the pipe in place, you must submit an application for a permit for the stream impacts. The USACOE should be contacted at (919) 876- 8441 to determine which Nationwide Permit is applicable to your project. Joint submittal of a Pre - Construction Notification to USACOE and DWQ will likely be required. The system modifies pH and TSS to meet stormwater permit limits.. However, plans and specifications were not prepared by a professional engineer as per 15A NCAC 2H .0138 and .0139. We were also informed that personnel created an unpermitted use of the clarified water for the bathroom commodes for a Reclaim purpose, as opposed to Reuse purposes. Also, flowers and grass were being watered with the treated water. The treatment provided does not allow for piping the water for flushing toilets, for potable water use, or for watering the landscape. Those reclaim uses require additional permitting with stringent permit limits. The water recovered by the Wooten system is appropriate only for making concrete. It was unclear from our discussion whether water has been piped to flush toilets or not. If so, they must be replumbed immediately to use an appropriate supply of water. Your experience has shown that lowering pH with carbon dioxide to achieve permit compliance results in rapid growth of green algae. The storage cell thus requires cleaning at some frequency to keep from overwhelming the sand filter. During out visit on 7/11, the storage cell was being washed out to remove algae by means of a sump pump. The highly turbid, concentrated algae was being discharged to the receiving stream, an illegal discharge that was causing a violation of stream water quality standards. Either some other means of disposal must be found, or cutting sunlight from that cell will terminate algal growth.

Wooten Garner Ready Mixed Plant / Wastewater Treatment System on 7/7/2005. Follow-up stream evaluation on 7/11/05 Permit No. NCG140236 Wake County Ken Schuster, and Myrl Nisely from RRO, along with Ken Pickle and Bethany Georgoulias, permit writers from Central Office, visited this site to review construction of a multicell settling system and pH adjusting system that provides reuse water for the plant. See the report from an earlier recon on 6/17/2005. A follow-up stream evaluation was made by Eric Kulz and Myrl Nisely for point 3 below. In-depth discussions were held with Plant Manager Danny Chapel and Environmental Supervisor James Washburn. The key factors covered were these: 1. There is a distinction between reuse (in concrete production) and reclaim (water used on a landscape or for flushing toilets). The water from this system is not to be used as reclaim water — only as reuse water. 2. The locally engineered treatment system is an impressive improvement in protecting the environment. It modifies pH and TSS enough to meet permit limits while also providing good quality water for reuse. This helps the facility reduce their cost of fresh water in concrete manufacture. As good as the system is, the Division feels that engineering by a professional engineer would have helped avoid an unfortunate mistake. Wooten's system is built against a stream that falls under the Neuse Basin buffer rules. An outside engineer would have likely caught that problem. Obtaining professional engineering input to design systems for an entire site is required by DWQ. 4. An evaluation by Eric Kulz from the RRO office declares that the structure is in Zone 1 of a subject stream, so is a violation of the buffer rules. See pictures attached. A decision will have to be made about the future of the installation. 5. During the visit on 7/1 1, the storage cell was being washed out to remove algae. This highly turbid water was being discharged to the stream when we arrived. The pumping stopped while we obtained a camera. See pictures. 6. It is apparent that a heavy rain will have enough velocity to flow past the treatment system and flow overland from the site. On 7/11, a dry day, water from simply washing the trucks had almost made its way to the edge of the concrete. See pictures. A speed bump or other diversion device is needed to assure runoff cannot occur, if the system is allowed to remain where it is. Stream Evaluation The Soils Map and aerial photos show a clearly defined stream passing through the Wooten facility. Earlier photos taken by DWQ in 2002 also show this feature.

This was later confirmed by a site evaluation by Eric Kulz, RRO wetlands group. Discussion was also held to make a distinction between reuse water and reclaim water. The former can be used in concrete and on the trucks, but should not be sprayed on the landscape nor used to flush toilets (reclaim useage). .A further observation was made that algae cleanout of the storage cell was being pumped to the creek, a violation of water quality standards. If the reuse system remains in use, a roof over the cell to eliminate light willbe needed to control algae. ' G W AT �R O 'C Mr. James Washburn S.T. Wooten, Inc. P.O. Box 2408 Wilson, NC 27894 Dear Mr. Washburn: Michael P. Easley, Governor William G. Ross, Jr., Secretary North Carolina Department of Environment and Natural Resources June 24, 2005 Alan W. Klimek, P.E., Director Division of Water Quality Subjects: URL for Tax Exemption Information Algal Growth After pH is Lowered After your demonstration to me of the new water control equipment at the Garner plant on 6/21/2005, you asked about the possibility of tax exemption. The following URL provides the regulation on tax certifications, GS 105-275. http://www.ncaa.state.nc.us/EnactedLegislation/Statutes/HTML/BySection/Chapter 105/GS 105-275.1hnl It appears that the equipment installed for environmental control and permit compliance will qualify. There is no application form. Rather, simply write a letter to the attention of Ken Schuster requesting tax certification, with a list of the pieces of equipment to be included and a justification that follows what is allowed in the regulation. I contacted our state expert on aquatic plants after my visit to ask why algae grows so well after the pH is lowered in the 51h cell. Algae species love CO2. With a little N & P, too, they will grow quite well. He suggests that we collect a sample of the water at a time of an algal bloom. He will examine it in an effort to determine what kind of algae it is. The most likely method of controlling it will be to put a roof or cover of some kind over that cell to keep light out. The fact that filter backwash water is returned to an earlier cell (No.2? — I don't recall exactly) might mean that the whole chain of cells will become seeded with algae. Perhaps the pH will be too high, though, for it to thrive there. More than likely this is a problem that is best solved as soon as possible, rather than for it to grow worse. I am interested in doing a little experimentation like this. If you will contact me on a day when conditions are right, I'll be glad to take samples of Cell 5 and the earlier cell and drop them to the lab for microscopic examination. Sincerely, Myrl A.

Wooten Ready Mixed Concrete Gamer Plant to View New Recycle Cells and pH Attenuation, Permit NCG140236 925 E. Garner Rd Gamer, NC Wake County Directions: 440 east to 40 toward Benson, Jones Sausage Rd exit, right to E. Garner Rd., left to cross over 40, then immediately take a dirt road to the right to enter the plant. This visit was made at the invitation of James Washburn to observe a new recycle system consisting of 4 settling cells plus a final holding cell in which pH is adjusted and from which water is taken for filtration and reuse. Upon my arrival, Mr. Washburn was spraying some of the water into the flowers and grass around the operations building. Site topography brings all water to the foreground of this picture, View from other end draining to this low spot to enter the system. After traveling through the first four cells to settle solids, the water is pumped from the 4`h cell into the 5`h cell, shown here. Ip; Cell 4 Cell 5 A portion of the water is continuously circulated from Cell 5 past the pH probe and CO2 injector and returned to Cell 5 (pipes not visible on left end of cell). CO2 is injected only when the probe detects pH > 9. (Pictures near the end of report) The spray of water returning to the cell in the picture above is a relief flow from the 10 hp pump used to transfer water to the trucks and batch plant. Reuse water passes through a sandfilter, and appeared to be a crystal clear final product. The filter cost $12,000, CO2 equipment cost $6000 and construction of the cells cost about $30,000. Cost of CO2 used is virtually insignificant at about $40 per cylinder. pH in Cell 4 was 11.0, while water taken from the red hose was pH 7.8. James said that once the pH is lowered in the final cell, algae grows profusely in that water. Mark Vander Borgh points out that CO2 is food for algae, so cutting the light to that cell may be necessary to eliminate algae. Backwashing the sandfilter into Cell 2 may be seeding the system for intense algal growth, too. Cell 5 holds 12,000 gallons. Using that source, about 250 cubic yards of concrete can be made from that cell. The facility typically produces 300 to 400 cu yd per day. It will be only in severe rainstorms that adjusted and filtered water will be discharged to the stream behind the pump building. Engineering Evolved Starting out, the first cell had only one hole for water to enter the system. During heavy rains, the collected water overflowed the site and ran down a hill next to the entrance driveway. A second hole was created. This still was not enough capacity, so a third is now in place. It may prove necessary to add more holes in the walls between cells, too, as experience dictates. The cell walls were first constructed with walls that came to the front at full height, squared off. Quickly these were run into by the trucks attempting to dump wash waters into cells 1 or 2. The walls are now angled Other Improvements A recently implemented BMP dramatically reduces the volume of water dumped into drum wash pits at Wooten sites, or even eliminates the need for a drum wash pit. If unused concrete returns to the plant on the last trip of the day, it is dumped onto the ground to harden. The strip of concrete is later popped up and crushed for fill during periodic crushing sessions. The empty drum then receives 48 to 50 oz. of Delvo plus only 50 gallons of drum wash water. This is stirred by careful control of drum rotation (forward and backward three or four times) to wet the entire surface of the drum, and is then held overnight. If specifications for the first batch the next day allow, new concrete is made on top of the Delvo mix. If not, the mix is dumped onto the ground to also be popped and crushed later. A crusher was operating during this visit. This reduces a pile of broken concrete pieces to a pile of fill material the plant can sell. Mr. Washburn asked about tax certification for this equipment installed to meet compliance. That appears to be possible, and information will be provided to him.
