V Ilk 1"'M61 • 2 NCDENR NORTH ,CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES Subject: Permit No. WQ0008778 Town of Farmville Land Application of Wastewater Residuals Pitt County Dear Mr. Hicks: In accordance with your application received on August 13, 1998, we are forwarding herewith Permit No. WQ0008778, dated January 11, 1999, to the Town of Farmville for the operation of a wastewater residuals land application program. The application indicates the facility used the Specific Oxygen Uptake Rate (SOUR) test to prove Vector Attraction Reduction (VAR) compliance. This test is not appropriate for thickened sludge. The town of Farmville must use an alternate method to prove VAR compliance. As per the attached letter dated November 17, 1998, SOUR may only be used if all of the conditions are met as outlined in the document. This permit shall be effective from the date of issuance until December 31, 2003, shall void Permit No. WQ0008778 issued March 31, 1994, and shall be subject to the conditions and limitations as specified therein. Please pay particular attention to the monitoring and reporting requirements contained 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 thirty (30) days following receipt of this permit. This request must be in the form of a written petition, conforming to Chapter 150E of North Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O.

This report must outline the actions taken or proposed to be taken to ensure that the problem does not recur. IV. GROUNDWATER REQUIREMENTS 1. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is for the disposal system constructed after December 31, 1983 is 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 is subject to immediate remediation action in addition to the penalty provisions applicable under General Statute 143-215.6A(a)(1). In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems 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. 2. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided. No land application of waste activities shall be undertaken when the seasonal high water table is less than three feet below land surface. is V. INSPECTIONS The Permittee or his designee shall inspect the residuals storage, transport, and application 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 maintain 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 five years from the date of the inspection and shall be made available to the Division or other permitting authority, upon request. 2. 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 application site or facility at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be kept under the terms and conditions of this permit; and may obtain samples of groundwater, surface water, or leachate. VI. GENERAL CONDITIONS This permit shall become voidable unless the land application activities are carried out in accordance with the conditions of this permit, the supporting materials, and in the manner approved by this Division. 2. This permit is effective only with respect to the nature and volume of wastes described in the application and other supporting data. 3. This permit is not automatically transferable. In the event that there is a desire for the facilities to change ownership or a name change of the Permittee, a formal permit request must be submitted to the Division accompanied by an application fee, documentation from the parties involved, and other supporting materials as may be appropriate. The approval of this request will be considered on its merits and may or may not be approved. 4.
