The groundwater recovery, treatment and disposal system shall be inspected daily for the first week, of its operation, then weekly for the . next month, and monthly thereafter. Monitoring may be performed remotely after 30 days of successful system operation, once it is established that the system is functioning properly. If it is determined that the system is malfunctioning or leading to the release of wastes to the environment, a threat to human health, or a nuisance, all repairs should be made as soon as possible and reported to the Raleigh Regional Office (see Section VI. NONCOMPLIANCE NOTIFICATION). All components of the groundwater recovery, treatment, and disposal system shall be properly weatherproofed to prevent freezing and failure of the system. 2. Upon classification of the wastewater treatment and remediation facilities by the Water Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate and employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s) to be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201.

WELL CONSTRUCTION/ABANDONMENT CRITERIA Prior to beginning waste disposal operations, Monitor Well MW-2 shall be repaired and a nested monitoring well pair consisting of one shallow well and one deep well, shall be installed at a location southeast of the injection wells to monitor groundwater quality to detect any migration of contaminants. The well(s) shall be constructed such that the water level in the well is never below the screened (open) portion of the well at any time during the year. The screened (open) portion of the well(s) shall be located at a depth appropriate to detect the treated waste or plume migration. The general location and name for each well is marked on Figure 2. Each monitoring well shall be constructed in accordance with this permit and as approved by the Raleigh Regional Office. 2. The six (6) recovery well(s) shall be constructed of 4-inch diameter PVC casing, 0.020-inch slotted PVC screen, and the screened interval of each well shall be located from 28 feet to 48 feet below land surface. The two (2) injection wells shall be constructed of 1-inch diameter PVC casing and the screened interval of each well shall be located from 43 feet to 53 feet below land surface. Prior to operation of the groundwater remediation system, the Permittee shall certify the mechanical integrity of the injection well(s) as defined by 15A NCAC 2C .0207. 4. Flow measurement devices shall be installed to monitor the volumes injected at each injection well. Also each injection wellhead shall be equipped to measure the injection pressure at the screened interval. If the injection pressure is greater than atmospheric pressure, the mechanical integrity of the injection well(s) shall be demonstrated according to 15A NCAC 2C .0207. 5. Pursuant to rule 15A NCAC 2C .0211(h), injection may not commence until construction of the injection wells is completed, the Permittee has submitted notice of completion of construction to the Raleigh Regional Office, and the regional office staff has inspected or otherwise reviewed the injection well and finds it in compliance with the permit. if the Permittee has not received notice from the Raleigh Regional Office of the intent to inspect or otherwise review the injection well within 10 days after the regional office has received the notice, the Pennittee may commence operation of the injection wells. 6. All well(s) (monitoring, injection and recovery) must be constructed by either a North Carolina Certified Well Contractor, the property owner, or the property lessee according to General Statutes 87-98.4(b)(2). If the construction is not performed by a certified well contractor, the property owner or lessee, provided they arc a natural person, must physically perform the actual well construction activities. All wells) must be constructed according to the North Carolina Well Construction Standards (15A NCAC 2C .0108 for monitoring and recovery wells, and 2C .0200 for injection wells) and any local county rules. 7.
