Klimek, P.E., Director Division of Water Quality August 27, 2004 Mr. Jerry Tweed Heater Utilities P.O. Box 4889 Cary, N.C. 27519 Dear Mr. Tweed: Subject NPDES Permit Issuance Permit No. NCO087998 Rand Meadows Phase II WTP Wake County Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended.) This permit authorizes Heater Utilities to discharge treated filter backwash from the Rand Meadows Phase II WTP to the unnamed tributary (UT) Juniper Branch, a class C NSW water in the Neuse River Basin. The permit includes discharge limitations and/or monitoring for flow, total fluoride, total suspended solids (TSS), total residual chlorine, manganese, lead, and zinc. A total residual chlorine limit of 17 ug/l has been added to reflect the Division's current policy for protection against chlorine toxicity instream. Please note that the Division currently has a fast track process for dechlorination systems including minimum design criteria. The Division's website provides both guidance and applications. In addition, please be aware that the NPDES Unit no longer issues Authorizations to Construct (ATCs). Effective July 1, 2004 requests for all ATCs and ATC packages should be submitted to the Construction Grants and Loans Section. The plans of the water distribution system are being returned to your consulting engineer under separate cover. The Division has adopted a new permitting strategy for water treatment systems, which includes increased monitoring requirements and monitoring frequencies for particular parameters. Therefore, this new NPDES, permit contains additional monitoring that existing WTP permits do not include.

The fluoride and zinc limits do not apply since this is backwash water from filters on a community well and not a surface water treatment plant where these chemicals are added. While the footnotes indicate that they only need testing if applicable, these parameters do not even appear in our other similar permits. 2.

The subdivision is served by single well (#3) at a pumping rate of 90 gpm. The average pumping time is 12 hours. Water quality problems with the source water are high iron and manganese. A granular filtration using a triple media bed of garnet, filter sand and coal is proposed. The tentative filter bed: 15"coal, 8" sand,10" of 3 sizes of garnet, 9" of 3 sizes of gravel covering bottom distribution. Basic process is pre -oxidation with chlorine and direct filtration with a multimedia filter bed. Three parallel filters required and an 5400 gallon backwash storage pressure tank used to provide treated water for backwashing before corrosion control chemicals are added. Backwashing will be at night when water demand is low and one filter bed will be backwashed at a time. It estimated that each filter would treat approximately 550 bed volumes before backwashing is needed. With a well pumping time of 12 hours per day, each filter will be able to run up to 6 days between backwashing events. Backwash rate will be 105 gpm per filter.

I did have a couple of quick comments after visiting the site last week. First, the application form was signed by a Michael L. Stewart. From what I understand he is not an Heater Utilities, Inc. employee but a consulting engineer for the project. I don't recall whether he is working for Heater Utilities or the developer. This is a minor point, but the question is whether or not he was authorized to sign the application for Heater. My second issue may be addressed in the information you are sending. However, the area surrounding the well site will ultimately be developed home sites on individual septic systems. this makes me wonder if they considered a non -discharge (subsurface disposal) option for this project as a alternative to a discharge??

Engineers Report: Rand Meadow water system will serve 88 single family residential connections at build out. The system will have one production facility with iron filters and produces 100 gpm water production and 1-5400 gallon hydro pneumatic storage tank. Rand Meadows will be connected to the Crest of Carolina water system. Total build out expected in 5 years. Design of Treatment System Subdivision is served by single well (#3) at a pumping rate of 90 gpm. Average pumping time is 12 hours. WQ problems are high iron and manganese. A granular filtration using a triple media bed of garnet, filter sand and coal is proposed. Filter bed: 15"coal, 8" sand, 10" of 3 sizes of garnet, 9" of 3 sizes of gravel covering bottom distribution.

With a well pumping time of 12 hours per day, each filter will be able to run up to 6 days between backwashing events. Backwash rate will be 105 gpm per filter. Alternatives Per engineer, Mike Stewart, Pump and haul for the filter backwash is not an option because there is nowhere that will take it. Its not domestic wastewater, neither Raleigh nor Fuquay will accept it. It's not septic enough to be considered domestic. It would throw off the balance of their treatment system. Drip or spray irrigation- Soil scientist recommendation Not enough available land for drip, and soils not really suitable. There is no sludge anticipated, therefore there is no residuals plan. The Rand Meadow system is also in review by the public water supply unit. Recommended limits Per the January 2004 DWQ WTP guidance, limits for a greensand filter WTP will be recommended for Rand Meadows. The permit will include monitoring for flow, zinc, manganese, and lead. There will be limits for TSS, TRC, pH and fluoride. TN and TP will be monitored because phosphate is an additive, and the receiving stream, UT Juniper Branch, has a C NSW classification. Alternatives: Individual wells rejected due to potential contamination and groundwater impact. There is an additional cost to homeowners by operating individual wells. Water demand: 88 connections * 400 gpd per connection = 35,200 GPD Well#3 will receive chlorination and phosphate as treatment and a filter will be installed to treat the iron present in the water.

The 0200 regulations were used for this evaluation. The evaluation was conducted by James L. Beeson. It is my understanding that this wastewater is considered to be industrial process waste and would require that a spray system have setbacks of 150 feet to property lines. This setback leaves no usable area remaining. A drip system would require a 50-foot setback. This setback and the 100 foot setback, along with the soils criteria of 12 inches to the seasonally high water table leaves approximately 28,000 square feet of usable material. The daily flow of the proposed backwash is 2,350 gallons/day. The typical water balance equation for the area in similar topography and vegetation would allow for an average of approximately 2 feet of water to be applied per year. This is equivalent to 15 gallons per square foot per year. The daily flow of 2,350 gallons multiplied by 365 days per year yields an annual flow of 857,750 gallons. The annual flow divided by the average application rate of 15 gallons per year yields an area requirement of 57,183 square feet of area required in order to dispose of the backwash flow. In my opinion the available area that meets the drip irrigation soil requirement and the setbacks to streams, ponds, and property lines is inadequate to accept the annual flow produced by the proposed water filter. The usable area is indicated on the enclosed map as area colored in green. The soils in this area barely meet the spray criteria in that they are normally 15 to 18 inches in depth to the seasonally high water table.

J' f V 1 8 2004 D SEAL 4/15/04 /10�_ Design Basis of Treatment System The Rand Meadows Subdivision is served by a single well (Well No. 3) at a pumping rate of 90 gpm. The average daily pumping time is estimated at 12 hrs (new system). The water quality problem at Well No. 3 is high iron and manganese. Iron (Fe II) is approximately 1.52 mg/L and manganese (Mn II) is approximately 0.20 mg/L. Both contaminants exceed the secondary MCL's of 0.30 mg/L and 0.05 mg/L, respectively, and treatment is required. The water quality of Well No. 3 is given in Appendix A. Granular filtration using a triple -media bed of garnet, filter sand, and coal is proposed. The ambient pH is relatively high at 7.7 and a need for pH adjustment is not anticipated. This treatment process is a proven one and does not require piloting. The basic process is one of pre -oxidation with chlorine and direct filtration with a multi -media filter bed. Three parallel filters are required and a 5400-gal backwash storage pressure tank is used to provide treated water for backwashing, before corrosion control chemicals are added. The backwash water will be discharged to a disposal location engineered S art -Proctor Engineering & Surveyii The treatment system layout in the new building is shown on Heater Utilities' Sheet No. 1. Note that the design capacity of the filtration system is 105 gpm and it will operate at 90 gpm. The filter bed shall be multi -media, consisting of coal, sand, and garnet, with a gravel and garnet under drain bed and a stainless steel hub and lateral distributor. Laterals are properly sized for flow distribution at the design flow rate and shall have 0.020" slots. The details of the bed and vessel design are shown in Sheet No. LEE-1 and in Table LEE-1 below. Optional chemical injection points are supplied for possible future use (See Heater Utilities Sheet No. 1). These include coagulant for the backwash water discharge line, and two (2) injection points (pH adjustment and other) for the well water before treatment.' Chlorine and phosphate injection points are provided for the treated water. • 1 Operation of Filters The three filter units shall operate in parallel and treat 30 gpm (capacity is 35 gpm) each. Backwashing is at night when water demand is low and one filter bed will be backwashed at a time. Sequential backwash is possible but not the normal operation. Normal operation is to have the three filters out of phase with respect to filter service, and have one filter unit backwash during the night. The frequency of backwashing will be determined by field experience and testing, but it is estimated that each filter will treat approximately 550 bed volumes (BV) before backwashing is needed. Using a well pumping time of 12 hrs/day, each filter will be able to run up to 6 days between backwash events. Using a design value of 3 days per run, one filter would be backwashed per day. The backwashing rate shall be 15 gpm/sq ft, or 105 gpm per filter. The backwash shall be followed by a rinse step to waste. The rinse (one filter) will be at 35 gpm for 5 min. Table LEE-1.

Report by Stewart -Proctor Total Discharge, gal/day 12,275 = 2 100 + 175 0 e The filter operation is controlled by a simple programmable timer -initiated stager control on each filter, using five (5) Normally -Open (NO) diaphragm valves per filter. The sequence of control for the service, backwash, and rinse cycles are detailed on the schematic shown on Sheet No. LEE-2, with the notations to correspond to the modified piping and valves shown in Heater Utilities Sheet No. 1. The modifications are needed to incorporate the 5400-gal System Backwash Storage Tank into the operation. System water will be used to provide the control pressure for operating the diaphragm valves. The general schematic shown in Sheet No. LEE-2 is conceptual and agrees in concept and intent with the actual piping schematic shown in Heater Utilities Sheet No. 1 drawing "Typical Filter Piping". Equipment Specifications The treatment control equipment cut sheets are presented in the "Manufacturer's Literature" section.
