In addition, the Wake County Manager's office must be notified prior to the initial application so that they will be aware that the operation has commenced. 2. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded unless the sites are maintained and operated in a manner which will protect the assigned water quality standards of the surface waters and ground waters. 3. The land application program shall be effectively maintained and operated as a non - discharge system to prevent the discharge of any wastes resulting from the operation of this program. 4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or groundwaters resulting from the operation of this program.

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 of Water Quality or other permitting authority, upon request. 2. Any duly authorized officer, employee, or representative of the Division of Water Quality 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.

The approval of this request will be considered on its merits and may or may not be approved. 4. The following are approved sites for residuals application (see attached map(s)): Application Area [acres] Site No. Owner/Lessee _ _ _ . _ (excluding buffers) Aa Town of Wake Forest 68.0 TOTAL AVAILABLE ACRES 68.0 a The western portion of this site shall be limited to land application of residuals only when the depth to groundwater in both piezometer monitoring wells PZ-1 and PZ-2 is greater than three feet. 5. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee to an enforcement action by the Division of Water Quality in accordance with North Carolina General Statute 143-215.6(a) to 143-215.6(c). 9 6. The annual administering and compliance fee must be paid by the Permittee within thirty (30) days after being billed by the Division.
