R JA N 2 9 2001 Winston-Salem F3e9ional Office Subject: NPDES Wastewater Permit Coverage Renewal White Rock Service Station COC Number NCG510439 Caswell County Your facility is currently covered for wastewater discharge under General Permit NCG510000. This permit expires on September 30, 2001. We are currently in the process of rewriting this permit and are scheduled to have the permit reissued by the summer of 2001. Once the permit is reissued your facility would be eligible for continued coverage under the reissued permit. In order to assure your continued coverage under the general permit, you must apply to the Division of Water Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in advance that your permit will be expiring. Enclosed you will find a general permit coverage renewal application form. This will serve as your application for renewal of your permit coverage. The application must be completed and returned with the required information by February 28, 2001 in order to assure continued coverage under the general permit. Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and could result in assessments of civil penalties of up to $10,000 per day. If the subject groundwater remediation project has been terminated, please complete the enclosed rescission request form. Mailing instructions are listed on the bottom of the form. You will be notified when the rescission process has been completed. If you have any questions regarding the permit coverage renewal procedures please contact the Winston-Salem Regional Office at 336-771-4600 or Aisha Lau of the Central Office Stormwater Unit at (919) 733-5083, ext. 578 Sincerely, Bradley Bennett, Supervisor Stormwater and General Permits Unit cc: Central Files Winston-Salem Regional Office 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone 919-733-5083 FAX 919-733-9919 An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper Al i � K � r ,t- t:��i 1. � a. �• �, ��:. `._ "y _. �,•!_.E cc: Permits and Engineering County Health Dept.

The filters will be installed in parallel so the system may continue to operate while one (1) of the filters is being back -washed. The filters have a design flow rate of 30 GPM. The units will be installed after the air stripper and before the bag filters and carbon units. 8) Receiving waters: aa) What is the name of the body or bodies of water (creek, stream, river, lake, etc.) that the facility wastewater discharges end up in? If the wastewater discharge is to a separate storm sewer system (4S), name the operator of the 4S (e.g. City of Raleigh). System will discharge to a drainage feature, to an unnamed stream, to Panther Branch to Hyco Lake. b) Stream Classification: Class C 9) Alternatives to Direct Discharge: Address the feasibility of implementing each of the following non -discharge alternatives a) Connection to a Regional Sewer Collection System - If the facility is existing and currently discharges to a POTW, when will connection be terminated? There is no regional Sewer Collection System available at this site, so connecting to the POTW is not applicable. b) Subsurface disposal (including nitrification field, infiltration gallery, injection wells, etc.) Subsurface disposal of the remediated water is not feasible at this site. There is an iron problem which over time will diminish the flow capacity of any subsurface discharge. Additionally there are seven extraction points at the site. By implementation of a subsurface discharge there is potential for hydraulic mounding and increasing the migration rate of the contaminant plume out of the designed capture zone. Finally the site is underlain by clay and saprolite making subsurface discharge not feasible at this site. c) Spray irrigation will not be feasible since there will not be enough open ground on the property to install a spray irrigation field. The alternatives to discharge analysis should include boring logs and/or other information indicating that a. subsurface system is neither feasible nor practical as well as written confirmation indicating that connection to a POTW is not an option. It should also include a present value of costs analysis as outlined in the Division's "Guidance For the Evaluation of Wastewater Disposal Alternatives". 10) Additional Application Requirements: For new or proposed discharges, the following information must be included in triplicate with this application or it will be returned as incomplete. a) 7.5 minute series USGS topographic map (or a photocopied portion thereof) with discharge location clearly indicated. b) Site map, if the discharge is not directly to a stream, the pathway to the receiving stream must be clearly indicated. This includes tracing the pathway of a storm sewer to its discharge point. NCG510000 N.O.I. c) If this application is being submitted by a consulting engineer (or engineering firm), include documentation from the applicant showing that the engineer (Or firm) submitting the application has been designated an authorized Representative of the applicant. d) Final plans for the treatment system (if applicable). The plans must be signed and sealed by a North Carolina registered Professional Engineer and stamped -"Final Design -Not released for construction". e) Final specifications for all major treatment components (if applicable). The specifications must be signed and sealed by a North Carolina registered Professional Engineer and shall include a narrative description of the treatment system to be constructed. f) Site map identifying the location of the monitoring wells, the recovery wells, and the treatment system unit. g) Analytical monitoring data which sufficiently characterizes the type and concentration of contaminants on site. This includes a listing of any chemicals found with the maximum observed concentrations reported. The data provided must be no older than one year prior to the date of this application. At a minimum, the following parameters must be reported: Benzene, Toluene, Ethylbenzene, Xylene, Lead, Naphthalene, Phenol, MTBE, 1,2-Dichlorethane, Fluorene and Phenanthrene. NCG510000 N.O.I.

The influent of the system will be connected to seven (7) existing monitoring/recovery wells on the site (See Figures 1-3). The groundwater will be extracted from the wells using vacuum. The groundwater will be transported to the system influent by a 2-inch schedule 40 PVC underground vacuum piping. This vacuum piping will be connected to a 120-gallon air/liquid separator tank. As the liquid fills the tank the float switches will be activated so a transfer pump will remove the water from the air/water separator to the oil water separator. After the oil/water separator there is another transfer pump that will transfer the water to the air stripper. The sump of the air stripper has four (4) float switches. Two (2) of the float switches will control the pump operation and two (2) of the floats will be alarm floats. One (1) alarm float will be a high/high float and the other will be a low/low float. The discharge pump will pump the water, from the air stripper sump, to the iron filtration system. After the water passes through the iron filtration system the water will pass through two (2) duplex bag filter housing plumed in series. After the bag filters the water will pass through two (2) liquid phase carbon units with 1,000 pounds of granular activated carbon in each vessel. The carbon units will be plumed in series. After the carbon vessel the water will pass through a non re-settable continuous read flow meter then be discharged to the drainage feature located toward the backside (northeast) of the property (See Figure 3). The non -aqueous phase liquid (NAPL) collected by the oil/water separator will be gravity drained to a 500-gallon NAPL holding tank. This tank is equipped with two float switches one (1) float is a warning light/alarm. The second float is a high/high alarm that if activated will shut the system down. When the NAPL tank warning light is activated arrangements will be made to have the NAPL tank pumped out and then disposed of at an approved facility. The iron filtration system will consist of two (2) 500 pound filters filled with green sand, one (1) 1,500- gallon tank, one (1) 2,000-gallon tank, and two transfer pumps. The iron filters will be plumed in parallel, and only one (1) iron filter will be operating at one time. This is done so there will be no system down time while the iron filters are being back washed. The 1,500-gallon holding tank is for the storage of the back washed water from the iron filters. This tank will have a man -way so the iron sludge can be removed. Additionally there will be a transfer pump connected to this tank so the water can be removed after the iron has settled out. This pump will be controlled by floats and timers. The second tank is a 2,000-gallon tank for water. The 2,000-gallon tank is the clean water holding tank for the back washing of the iron filters. The 2,000-tank will be filled from the clean water from the system, which will be supplied to the tank after the carbon units. The pump on this tank will be controlled by a pressure switch, which is connected to the iron filters. When the pressure in the active iron filter reaches or exceeds 40 PSI the system will disengage that iron filter and will engage the other filter. After this the pump on the 2,000-gallon tank will be activated and start back washing the iron filter, which has just been taken off line. Alternatives to direct discharge were evaluated. There is no regional sewer collection system available at this time so connection to the POTW is not applicable. Subsurface disposal of the remediation system is not feasible at this site. There is an iron problem which will over time diminish the capacity of any subsurface discharge. Additionally by implementation of a subsurface discharge there is potential for hydraulic mounding and increasing the migration of the contaminant plume out of the designed capture zone. Finally, the site is underlain by clay and saprolite, making subsurface discharge not feasible at this site. Spray irrigation is not feasible since there is not enough open ground on the property to install a spray irrigation field.
