Sanders, Jr., P.E. i We have reviewed the referenced draft permit for the Dixon Water Treatment Plant transmitted by your letter dated June 20, 2007. We have the following questions for your consideration: 1. Since we do not disinfect our effluent with chlorine prior to its discharge, why is it proposed that we monitor total residual chlorine? 2. Due to the nature of the operation, the flow from the lagoons is intermittent. How do we use the composite sampler to sample an intermittent flow? 3. As you are aware, the receiving stream is tidal resulting in a submerged outfall. Where do we need to locate the proposed composite sampler? You attention to these comments are appreciated. Should you have any questions, please do not hesitate to contact us. Sincerely, Francis A. Sanders, Jr., P.E.

PART II - BACKGROUND AND HISTORY Facility had two 0.915 million gallon settling lagoons (with 60 ml HDPE liners) in series. PART III - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1) Volume of wastewater to be permitted: As per permit application: • Outfall 001— No flow limit given, flow is approximately 0.29 MGD 2) What is the current permitted -flow limit? • Outfall 001— None given in previous permit 3) Actual treatment capacity of the current,faciliV? Facility recently constructed another settling lagoon with 915,000 gallon capacity lined with 60 ml HDPE. Total treatment lagoons are three 915,000 gallon lined lagoons. 4) Date(s) and construction activities allowed by previous Authorizations to Construct issued in the previous two ,years: A to C given on July 25, 2006 from CG&L for the construction of one new 915,000 gallon settling lagoon. 5) Please provide a description of existing or substantially constructed wastewater treatment acilities: This water treatment plant utilizes conventional treatment (suspended solids settling), green sand filtration for iron and manganese removal, ion exchange for calcium and magnesium removal, carbon filtration for TOC removal. The facility backwashes with chemically treated potable water. Potential treatment additives are potassium permanganate and chlorine for disinfection, and fluoridation. Treated water is used for backwashing. The facility has three lined lagoons with a 915,000 gallon capacity each. Influent introduced to the first lagoon passes through all three lagoons in series before exiting to the effluent well. Influent introduced to the third lagoon makes a one pass across the third lagoon to the effluent well. Settling time is considerably shorter. Typically influent would be introduced to the first lagoon to provide adequate detention time for settling. The influent flow is 1300 gpm as a batch feed. There are no chemical additions to promote settling. Effluent from the effluent vault is pumped using one 50 gpm pump (driven by one 3 horsepower motor) and a 500 gpm pump (driven by one 20 horsepower pump). 6) Please provide a description ofproposed wastewater treatment, facilities: N/A 7) Possible toxic impacts to surface waters: Fluoride, chlorine, magnesium, manganese, and any recoverable metals from the treatment of groundwater (should potential contamination exist). 8) Pretreatment Program (POTWs only): N/A 9) Residuals handling and utilization/disposal scheme: The facility dewaters the solids from the lagoon in order to pass the paint filter test for disposal in the Onslow County Landfill. The schedule for removing solids is every three years to maintain adequate treatment capacity for settling. 10) Compliance history for this facility within the past permit cycle is as follows: Excellent, no history of compliance problems within the last permit cycle with the exception of failure to secure an A to C to add the additional lagoon for treatment. 11) Treatment plant classification: Type: Physical/Chemical WTP Class: Grade I 12) SIC Code(s): 4941 PART IV - OTHER PERTINENT INFORMATION 1. Is this , acili , being constructed with Construction Grant Funds or are any public monies (municipals only,) involved? N/A 2. Special monitoring or limitations (including toxicity) requests: Per 15A NCAC 02B.0224 (ii) Total suspended solids: Discharges of total suspended solids (TSS) shall be limited to effluent concentrations of 10 mg/L for trout waters and PNAs. Per 15A NCAC 02B.0244 (vii) Toxic substances: In cases where complex wastes (those containing or potentially containing toxicants) may be present in a discharge, a safety factor shall be applied to any chemical or whole effluent toxicity allocation. The limit for a specific chemical constituent shall be allocated at one-half of the normal standard at design conditions. Whole effluent toxicity shall be allocated to protect for chronic toxicity at an effluent concentration equal to twice that which is acceptable under design conditions. In all instances there may be no acute toxicity in an effluent concentration of 90 percent. 3. Important SOC. JOC or Compliance Schedule dates: N/A 4. Alternative Analysis Evaluation: N/A 5. Other Special Items: N/A PART V - EVALUATION AND RECOMMENDATIONS The pen -nit limitation for TSS should be 10 mg/L due to the discharge to PNAs (HQW). Please see comments in Part IV. 2.Other Pertinent Information, Special Monitoring or Limitations (including toxicity requests) above. Please include the total residual chlorine limit of 17 µg/L. Pursuant to Permitting Strategy for Ion Exchange WTPs issued in January 2004, include the minimum monitoring requirements as per the attachment (Appendix B page 5). The monitoring frequency is based upon the flow, therefore since this facility discharges less than 0.5 MGD, the monitoring frequency should be as follows; 2/month if limited and monthly for those parameters not limited. Fluoride limit of 1800 µg/L should be imposed and manganese should be monitored (since it is not a parameter of concern for IE WTPs) per the Permitting Strategy for Greensand Filtration Water Treatment Plant issued January 2004. The Wilmington Regional Office recommends reissuance of the permit in accordance with the White Oak River Basin Plan permitting strategy provided no significant adverse public comment is received. The Wilmington Regional Office also requests that the recommendations provided herein are considered in the reissuance of Permit No. NC0058271.
