Ross Jr., Secretary Gregory J. Thorpe, Ph.D., Acting Director August 13, 2001 MR. J. RUSSELL ALLEN, CITY MANAGER CITY of RALEIGH POST OFFICE BOX 590 RALEIGH, NORTH CAROLINA 27602-0590 Dear Mr. Allen: 11kT?W'J IT41 A& 0 0 NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES Subject: Permit No. WQ0002708 City of Raleigh Wrenn Road Spray Irrigation Facility Wastewater Treatment and Spray Irrigation System Wake County In accordance with your permit renewal application received on September 28, 2000 as well as the additional information received on March 2, 2001 and May 1, 2001, we are forwarding herewith Permit No. WQ0002708, dated August 13, 2001, to the City of Raleigh for the continued operation of the subject wastewater treatment and spray irrigation facilities. This permit shall be effective from the date of issuance until July 31, 2006; shall void Permit No. WQ0002708, issued on April 30, 1996; and shall be subject to the conditions and limitations as specified therein. This permit approves the continued operation of the subject wastewater treatment and spray irrigation facilities for another five-year cycle. In addition, with this issuance of this permit, ownership as well as operation and maintenance responsibilities for the facilities are acknowledged by the Division of Water Quality (Division) to have transferred from the Town of Garner to the City of Raleigh in accordance with the March 1, 2001 deed merging the water and sewer utilities of these two municipalities. Finally, this permit approves the continued operation of a calcium hypochlorite disinfection system that was installed at the facilities to replace an existing system that utilized chlorine gas, a modification to the facilities that was made without request and receipt of prior approval from the Division and for which the Town of Garner received a notice of violation on February 14, 2001. Please take the time to review this permit thoroughly as some of the conditions contained therein may have been added or changed since the last issuance of this permit. Of special interest are the following new, amended, and modified conditions: ♦ System_ DescKiption: The description of the permitted wastewater treatment and spray irrigation facilities has been amended to reflect several changes made during the last permit cycle. These include permanent capping of some of the sprinklers such that the wetted area of the spray irrigation facilities is not 269.72 acres (i.e., previously approximately 298 acres). This reduction results in the limitation of the volume of wastewater effluent that may be irrigated onto the wetted area of the spray irrigation facilities (i.e., reduced to 1.29 million gallons per day from 1.54 million gallons per day). In addition, the wastewater treatment facilities have been modified to replace an existing gas chlorination system with a disinfection system that utilizes calcium hypochlorite. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone (919) 733-5083 Fax (919) 715-6048 An Equal Opportunity Affirmative Action Employer 50% recycled/100% post -consumer paper ♦ Section II: Any pretreatment requirements related to this permit shall be covered under the City of Raleigh's existing Division -approved Pretreatment Program. Condition III. 2.: This condition has been amended to reflect the adoption of new rules by the Water Pollution Control System Operators Certification Commission (WPCSOCC). The referenced regulation is now 15A NCAC 8G .0202. ♦ Condition III. 3.: This condition has been amended to reflect that a suitable vegetative cover needs to be maintained on the wetted area of the spray irrigation facilities year round. ♦ Condition III. 8.: This condition has been amended to specify that only wastewater effluent from the City of Raleigh's Spray Irrigation Facility may be sprayed onto the wetted area of the spray irrigation facilities. ♦ Condition IV. 2.: This is a new condition that is required in all permits issued to non -discharge wastewater treatment and disposal systems in the State of North Carolina. Specifically, this condition details the requirements for complying with the influent flow measuring policy adopted by the Division on May 31, 2000. Daily influent flow volumes must now be reported on Form NDMR-1 such that this form would be submitted on a monthly basis. ♦ Condition IV. 6_: Because of the Division's influent wastewater flow measurement policy, Form NDMR-1 must now be submitted on a monthly basis (i.e., following installation of the new influent flow measurement device). Note also that this condition has been modified to reflect the new mailing address to be used when submitting Form NDAR-1 and NDMR-1. ♦ Condition V. L: This is a new condition that confirms that irrigation of wastewater effluent may take place throughout the year. ♦ Condition V. 3.: Note that the Division's Groundwater Section is requiring that the nomenclature assigned to the existing groundwater monitoring wells be changed. Total ammonia -nitrogen must now be monitored (i.e., in Lieu of ammonia -nitrogen) in the groundwater, and additional methods for analyzing for the concentration of volatile organic compounds in the groundwater are listed in this condition. Furthermore, this condition has been amended to reflect the new mailing address to use when sending in groundwater quality monitoring reports. ♦ Condition VII. 3.: This condition has been amended to reflect the fact that an application fee is no longer required when making an application to the Division to transfer this permit to a new owner or to reissue this permit such that it reflects a name change of the Permittee. ♦ Condition VII. 5.: Language has been added to this condition to provide examples of some other rules and regulations that may affect non -discharge systems like this one. Pay particular attention to the monitoring requirements in this permit. Failure to establish an adequate system for collecting and maintaining the required operational information will result in future compliance problems. If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing upon written request within 30 days following receipt of this permit. 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, NC 27699- 6714. Unless such demands are made, this permit shall be final and binding. 2 If you need additional information concerning this matter, please contact Ms. Shannon Mohr Thornburg at (919) 733-5083, extension 353.

The above -described facilities are intended to serve the City of Raleigh and its wastewater customers (i.e., including the Town of Garnerj with no discharge of wastes to surface waters, pursuant to the permit renewal application received on September 28, 2000 as well as the additional information received on March 2, 2001 and May 1, 2001, and in conformity with the project plan, specifications, and other supporting data subsequently filed and approved by the Department of Environment and Natural Resources and considered a part of this permit. This permit shall be effective from the date of issuance until July 31, 2006; shall void Permit No_ WQ0002708, issued on April 30, 1996; and shall be subject to the following specified conditions and limitations: I. PERFORMANCE STANDARDS The wastewater treatment and spray irrigation facilities shall be effectively maintained and operated at all times so that there is no discharge to the surface waters nor any contamination of groundwater that will render them unsatisfactory for normal use. In the event that these facilities fail to perform satisfactorily, including the creation of nuisance conditions or failure of the irrigation areas to assimilate the wastewater adequately, the Permittee shall take immediate corrective actions including those actions that may be required by the Division of Water Quality (Division), such as the construction of additional or replacement wastewater treatment and disposal facilities. 2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface waters or groundwater resulting from the operation of the wastewater treatment and spray irrigation facilities. 3. The residuals generated from the wastewater treatment facility shall be disposed in accordance with North Carolina General Statute § 143-215.1 and in a manner approved by the Division. 4. Diversion or bypassing of the untreated wastewater from the wastewater treatment and/or spray irrigation facilities shall be prohibited. The Pemvttee shall, however, maintain the capability to divert a minimum of 25,000 gallons per day of wastewater flow that would typically be tributary to the wastewater treatment and spray irrigation facilities to the Permittee's Neuse River Wastewater Treatment Plant (i.e., NPDES Permit No. NC0029033) at all times. Alternate treatment and/or disposal facilities may be designated to receive this influent wastewater flow after approval has been applied for and granted by the Division. 5. The following buffers shall be maintained by the wastewater treatment and spray irrigation facilities: a. 400 feet between the wetted area and any residence or place of public assembly under separate ownership, b. 150 feet between the wetted area and any property line, c. 100 feet between the wetted area and any well (i.e., with the exception of an approved groundwater monitoring well), d. 100 feet between the wetted area and any drainageway or surface water, e. 50 feet between the wetted area and any public right-of-way, f. 100 feet between wastewater treatment twits and any well (i.e., with the exception of an approved groundwater monitoring well), and g. 50 feet between wastewater treatment units and any property line. Some of the buffers specified above may not have been included in previous permits for the wastewater treatment and spray irrigation facilities. The Permittee does not have to modify previously -approved facilities to comply with these buffers unless specifically required by the Division to do so, nor are these buffers intended to prohibit or prevent modifications that may be required by the Division to improve the performance of the existing facilities. These buffers do, however, apply to modifications of the system that are for the purpose of increasing the wastewater flow that is tributary to the facilities. These buffers do apply to any expansion or modification of the facilities and apply in instances in which the sale of property would cause any of the buffers with which the facilities now comply to be violated. The Permittee shall be advised that any modification to the existing facilities will require a permit modification_ II. PRETREATMENT REQUIREMENTS A.

Any method used shall meet the following qualifications: (1) The laboratory shall be Division certified to run any method used. (2) The method used shall, at a minimum, include all the constituents listed in Table VIIi of Standard Method 6230D. (2) The method used shall provide a PQL at 0.5 µg/L or less, which shall be supported by laboratory proficiency studies as required by the Division's Laboratory Certification Unit. Any constituents detected above the MDL, but below the PQL at 0.5 µg/L, shall be qualified (estimated) and reported. If any VOCs are detected by the methods listed, then the Raleigh Regional Office Groundwater Supervisor. telephone number (919) 571-4700, shall be contacted immediately for further instructions regarding any additional follow-up analyses required. The results of all initial and follow-up analyses shall be submitted simultaneously. If TOC concentrations greater than 10 milligrams per liter are detected in any downgradient groundwater monitoring well, additional groundwater sampling and analysis shall be conducted to identify the individual constituents comprising the TOC concentration. If the TOC concentration in the background (i.e., upgradient) groundwater monitoring well exceeds 10 milligrams per liter, this concentration shall be taken to represent the naturally -occurring TOC concentration in the groundwater. Any exceedance of this naturally -occurring TOC concentration in downgradient wells shall be subject to additional groundwater sampling and analysis as described above. The measurement of water Ievels shall be made prior to sampling the groundwater for the remaining parameters. The depth to water in each groundwater monitoring well shall be measured from the surveyed point on the top of the casing. The results of the sampling and analysis shall be received on the "Groundwater Quality Monitoring: Compliance Report Form" (i_e., GW-59 Form) on or before the last working day of the month following the sampling month at the following address: NCDENR-DWQ Groundwater Section Permits and Compliance Unit 1636 Mail Service Center Raleigh, North Carolina 27699-1636 The COMPLLANCE BOUNDARY for disposal systems shall be as specified by regulations in 15A NCAC 2L (i.e., "Groundwater Classifications and Standards"). The Compliance Boundary for disposal systems individually permitted after December 31, 1983 shall be established at either (1) 250 feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is closest to the waste disposal area. An exceedance of groundwater quality standards at or beyond the Compliance Boundary shall be subject to immediate remediation action in addition to the penalty provisions applicable under North Carolina General Statute § 143-215.6A(a)(1). In accordance with 15A NCAC 2L, a REVIEW BOUNDARY shall be established around the disposal system midway between the Compliance Boundary and the perimeter of the waste disposal area. Any exceedance of standards at the Review Boundary shall require remediation action on the part of the Permittee. 5. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided. VI. INSPECTIONS Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to ensure proper operation of the wastewater treatment and spray irrigation facilities. 2. The Permittce or his designee shall inspect the wastewater treatment and spray irrigation facilities to prevent malfunctions and deterioration, operator errors and discharges which may cause or lead to the release of wastes to the environment, a threat to human health, or a nuisance. The Permittee shall keep an inspection log or summary including at least the date and time of inspection, observations made, and any maintenance, repairs, or corrective actions taken by the Permittee. This log of inspections shall be maintained by the Permittee for a period of three years from the date of the inspection and shall be made available upon request to the Division or other permitting authority. Any duly authorized officer, employee, or representative of the Division may, upon presentation of credentials, enter and inspect any property, premises or place on or related to the wastewater treatment and/or spray irrigation facilities at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be maintained under the terms and conditions of this permit, and may obtain samples of groundwater, surface water, or leachate. VII. GENERAL CONDITIONS This permit shall become voidable unless the wastewater treatment and spray irrigation facilities are constructed in accordance with the conditions of this permit, the approved plans and specifications, and other supporting data. 10 M 2.
