Hunt, Jr., Governor Bill Holman, Secretary Kerr T. Stevens, Director October 11, 2000 Ms. Veronica J. Ellis Carolina Pines Utility Company 390 Carolina Pines Boulevard New Bern, North Carolina 28560 NCDENR Subject: Issuance of NPDES Permit NCO056618 Carolina Pines Estates WWTP Craven County Dear Ms. Ellis: 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). Your facility discharges to waters within the Neuse River Basin. All streams within this basin have been designated nutrient sensitive waters (NSW) as a result of environmental problems including algal blooms in the estuary. The North Carolina Environmental Management Commission recently adopted rules establishing the Neuse River Basin Nutrient -Sensitive Raters Management Strategy to reduce phosphorus and nitrogen inputs. The related point source r7de (15A NCAC 2B.0234) intends to reduce, by 30%, total nitrogen (TN) discharges by the year 2003. Because of this, revised nutrient limits have been imposed on facilities with NPDES permits. The rule specifies that individual wastewater discharges to the Neuse River Basin, with 1995 permitted flows of 0.500 MGD or higher shall be allocated an annual mass load of total nitrogen. The allocation for your facility is 5,632 pounds per year. An annual TN limit of 5,632 pounds per year has been added to your permit's 0.5 MGD effluent limitations. All facilities with permitted flows greater than or equal to 0.5 MGD are receiving a TN limit for this permit cycle. Your facility is currently operating at a permitted flow of 0.125 MGD, with TN monitoring (but no limit). However, if the permitted expansion to 0.5 MGD is undertaken your facility must comply with the annual TN limit. The Division recommends that you evaluate the cost to install nutrient removal equipment at your facility. The Division also recommends you evaluate alternative discharge options such as wastewater reuse, spray irrigation, subsurface discharge systems, or connecting to a larger regional system. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone (919) 733-5083 FAX (919) 733-0719 An Equal Opportunity Affirmative Action Employer Visrr us ON THE rNTERNET @ hftp://h2o.enr.state.nc.us/NPDES • � Y A public hearing was held May 4, 2000 in New Bern due to public interested generated as a result of the renewal of this (and other) NPDES permits. This final permit incorporates some of the comments and concerns raised during that hearing, as well as the recommendations of the Hearing Officer and the NPDES Unit staff. The following changes were made: • The permittee is required to complete a Wastewater Management Plan within 180 days of the effective date of the permit. The completed plan must be submitted to the Division's NPDES Unit no later than April 30, 2001. The details of the plan should include estimation of future flows, an evaluation of alternatives to wastewater discharge, an assessment of the installed facility, a facility optimization plan and a biosolids management plan. Please refer to the Wastewater Management Plan special condition (Part I. A. (4.)) in the permit. • In deference to fishing, swimming and boating activities near the discharge point, the Permittee shall install and maintain a sign in proximity to Outfall 001 (see Part I. A. (5)). If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding. Please note that this permit is not transferable except after notice to the Division. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be required.

Facilitv Description At the time of the Hearing, this permittee contracted operation of its facility to Tarheel Water and Wastewater. At the Hearing, Carolina water Service announced plans to assume operation of the facility by the end of June 2000. Treatment consists of dual aeration basins, dual clarifiers, tablet chlorination, and sludge digestion. Permit Summary The permit contains phased effluent limits for discharge flows of 0.125 and 0.500 MGD to the Neuse River. Until expansion above 0.125 MGD: • BOD is limited at 30.0 mg/L (monthly average) • Ammonia nitrogen and total residual chlorine are both monitored, but not limited • Total Phosphorus is limited to a Quarterly Average of 2.0 mg/L. After expansion above 0.125 MGD: • BOD is limited at 5.0 mg/L & 10.0 mg/L (summer & winter monthly averages) • Ammonia is limited at 2.0 mg/L & 4.0 mg/L (summer & winter monthly averages) • Total Residual Chlorine is limited at 13 µg/L • Total Nitrogen is limited to 5,632 pounds per year • Total Phosphorus is limited to a Quarterly Average of 2.0 mg/L. Public Comments JoAnne Dove - NRF • The NRF believes this facility has been dumping sludge into the river. They want a sludge production & disposal analysis conducted for the past 5 years of operation. The NRF says local residents have complained about odor and foaming. • The permittee should submit an EAA by 12/31/00. • The permittee should explore non -discharge means of wastewater disposal (reuse, irrigation, etc.). • The permit renewal should require 5 & 2 limits at the current flow, as well as 5 mg/L TN and 2.0 mg/L TP. Don Lawrence — Carolina Pines (attorney) • No plans to expand to 0.5 MGD, and it's unlikely that additional capacity will be necessary. • No POTW connection available, and none expected for several years. He also said that there was insufficient land for a reuse/irrigation system. Mr. Daniel — downstream neighbor • Suggested that the outfall be moved an additional 450 feet into the river (for a total distance from shore of ca. 1200 feet). He also suggested that warning signs be placed near the outfall, as local residents are known to fish and crab very close to the outfall. • Effluent sampling should be done in the river (at the outfall). - 1 - Carolina Pines WWTP NC0056618 DWQ Response and Discussion • On the date of the hearing, this facility looked like a victim of indifferent maintenance. There was a lot of peeling paint, a small leak in a sludge return line and cloudy water in the clarifier. The plant is under -loaded, with only one treatment train in operation. Effluent data show no violations (apart from one quarterly TP violation in December 1998) largely because the plant doesn't discharge much effluent. • When staff discussed the poor appearance of the facility with Jim Highly of Carolina Water Service, he promised that those deficiencies would be addressed immediately when CWS took ownership of the facility. • However, Mr. Highly wanted to retain the 0.5 MGD limit in the permit. The permittee and CWS need to reach some decision on the future flow needs for this site. Elimination of the 0.5 MGD flow would greatly please the NRF. Recommended Action(s) • Consider a TRC limit for the 0.125 MGD flow, pending further comment from the Washington Regional Office on this issue. • Require warning sign(s) at the outfall and consider requiring extension of the outfall line. However, the potential hazard of a 1200-foot outfall line in water less than ten feet deep should be evaluated before such an extension is suggested. • Re -issue the permit with the following language to address other concerns: A. (4.) WASTEWATER MANAGEMENT PLAN No later than 180 days after the effective date of this permit, the Permittee shall submit to the Division a wastewater management plan. The plan shall include, at a minimum, the following elements: • Future flows. Provide estimates of wastewater flows and characteristics for the next 10-20 years and the basis for those estimates, including assumptions and calculations. • Alternatives analysis. Conduct a technical and economic evaluation of wastewater disposal alternatives, specifically including at least the following alternatives: • connection to the New Bern wastewater collection system, • conversion to a spray irrigation system • implementation of a reuse program • any combination of the above options The analysis and report should be consistent with the FAA guidance document provided by the Division.

Through this process we have tried to take into account their professional expertise and experience. This has been a real asset as we tried to reduce this hearing request to only those facilities that we feel have significant problems and for whom we saw no acceptable near term solution. In addition, we wanted this process to be useful in highlighting what we see as significant and widespread problems in the permitting and operating of discharge wastewater treatment facilities. While some of the issues we will address cannot be rectified through any modification to these particular permits, we must use this oppottmity to comment more fully on the entire process since this is the only opportunity public interest groups have to raise these concerns. We also recognize, that many of these problems are exacerbated by the lack of adequate resources provided for your division, we will also consistently identify these problems and call attention to the legislature's responsibility to provide those resources if we are to have effective clean water programs in North Carolina.

Bill Holman Greg Thome Coleen Sullins Dave Goodrich ,t x NC DENR / DWQ / NPDES Unit FACT SHEET FOR PERMIT DEVELOPMENT : Facility Information - Facility: Carolina Pines Utility Company / Carolina Pines Estates WWTP NPDES Permit: NCO056618 Permitted Flow: 0.5 MGD ultimate capacity; currently at 0.125 MGD Facility Class: II Type of Waste: 1000 domestic Permit Status: Permit renewal County: Craven Stream Characteristics . Receiving Stream: Neuse River Stream Classification: SB-NSW Subbasin: 30410 Miscellaneous, - Regional Office: Washington USGS Topo Quad: Havelock (H31 NW Summary This first permit for this facility was issued on November 1, 1983. The facility received Authorizations to Construct on July 19, 1984 and March 21, 1985. The installed treatment works began discharging in November 1987. The facility's current treatment capacity is 0.125 MGD. The most recent permit renewal, issued on May 31, 1994, allows for expansion to 0.5 MGD; to date, no Authorization to Construct (AtC) request for expansion above 0.125 MGD has been submitted. Compliance data for the years 1996-1999 were retrieved from SIPS for review. During that time period, no flow violations were noted. One violation of the Total Phosphorus quarterly limit occurred in December 1998 (see attached spreadsheet). No other violations occurred during the period reviewed. The Washington Regional Office prepared a staff report for this facility on October 30, 1998. At that time the plant was operating only one of the two installed treatment trains. The staff report recommended installation of a total residual (TRC) chlorine limit to reduce the potential for chlorine toxicity in the receiving stream. The draft includes the existing 13 µg/L TRC limit for the expanded flow, but does not have a TRC limit for the 0.125 MGD flow, pending further input from the Regional Office and the Aquatic Toxicology Unit. Note to WaRO: Please comment on any changes at the facility since the last staff report. Include any additional information/recommendations for a chlorine limit at 0.125 MGD flow. The Neuse River Foundation has requested a Public Hearing on several permits in the Neuse River basin, including this permit. The request for Hearing was received prior to completion of the draft permit. The Hearing will be held in New Bern on May 4, 2000. The permittee was notified by telephone on April 6, 2000. The permittee's attorney contacted the NPDES Unit on April 7, 2000 to discuss the Hearing. The Neuse River mainstem does not appear on the (Final draft) 2000 303(d) list. The draft permit includes an annual Total Nitrogen (TN) limit of 5,632 pounds per year. The TN limit is a requirement for all NPDES permits with permitted flows of 0.5 MGD or greater. Instructions for calculation of monthly and annual TN loadings are included in the draft at Part I. A. (3.).

We might be allowed to go forward in late June/early July, but we can't be certain. Unless Dave can get some decent candidates to interview, we may still have only 5 engineers writing permits at that time... assuming we don't lose anyone else. If you think Carolina Pines needs a change in limits or increased monitoring, type up your recommendation and send it to me. I'll make sure that the renewed version of NC0056618 incorporates your suggestions. Or, if you'd rather, have the folks at Aquatic Tox provide us with suggested permit language to reflect any changes in tox testing/monitoring. We'll plan to implement your recommendations (or those of the tox folks) when the permit is reissued. If you think a change should be instituted before then, let me know. Thanks for keeping me informed on this - let me know what else you discover. CHW Carolina Pines NCO056618 Subject: Carolina Pines NCO056618 Date: Fri, 30 Apr 1999 10:35:31 +1100 From: "Brad Shaver" <Brad_Shaver@waro.enr.state.nc.us> Organization: WaRO-DENR To: Charles_Weaver@h2o.enr.state.nc.us Charles, I wanted to ask you a question about a facility which has not been issued their renewal and the Region has found some toxicity problems. I conducted a toxicity inspection because I was under the impression that they were discharging very high levels of chlorine. The results of the inspection was 28.3% chronic value. The daphnia died at 40, 70, and 90% of effluent concentration. I am conducting a second test under the advisement of Aquatic Tox which will be based on their impressions of their projected tox limits. If this test fails I would like to use this information to require a chlorine residual limit. Give me a call about this issue and lets discuss the possiblities.

Other Special Items: PART IV - EVALUATION AND RECOMENDATIONS Carolina Pines Estates is a growing privately owned community, which is only one-third developed to date. The average flow through the plant in the last year was 25,000 GPD. Due to the low flow of wastewater the treatment facility is only utilizing half of its treatment capacity by operating only one of the dual 75,000-gallon trains. The active permit needs to be modified to include the above description of the existing facility. The permit as written has some inconsistencies with the existing treatment works. Carolina Pines will be considered in the new nutrient reduction strategy and will likely have more restrictive limits. A consideration needs to be made to place a chlorine limit on the effluent leaving the treatment plant. The waters discharged to are recreational waters with both commercial and sport fishing. Present chlorine levels averaging 30 ug/1 may have toxic effects to juvenile fish species. It is recommended that the permit be reissued considering the above comments.
