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. 11. The permittee shall submit, before December 31, of each calendar year, an annual report to the regional groundwater supervisor at the Winston-Salem Regional Office outlining the injection volumes and the water levels measured within the infiltration gallery observation well. 12. The system will initially perform at a pumping rate not to exceed 3.62 gallons per minute. This rate will be maintained for sixty (60) days and the daily water level readings in the water -level monitoring well, along with a record of float -activated system shutdown events, will be furnished to the regional groundwater supervisor a the Winston-Salem Regional Office on a weekly basis during that time. 13. A 4-inch diameter water -level monitoring observation well shall be constructed as part of the infiltration gallery, as per the construction methods and specifications set forth in in the subject permit application. The well will be labeled P-1 and will comply with the regulations set forth in 15A NCAC 2C .0108 (Standards of Construction of Wells Other than Water Supply) and any other State and Iocal laws and regulations pertaining.to well construction. 14. The water -level monitoring well (P-1) at the infiltration gallery will be equipped with a float -activated high-level shutoff device which will shut down the remediation system when the water level in the infiltration gallery rises to within three (3) feet of the top of the gallery. The shutoff device will be designed such that the remediation system will remain off until the water level in the well falls to an elevation of five (5) feet below the top of the gallery. 15. The regional groundwater supervisor at the Winston-Salem Regional Office, telephone number (910) 771-4600, shall be notified at least forty-eight (48) hours prior to the construction of the P-1 monitoring well so that an inspection can be made of the monitoring well location. Such notification shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State holidays. 16. The water level in the P-1 monitoring well will be measured at least once every day for the duration of the permit, and the information will be provided to the Regional Groundwater Supervisor at the Winston-Salem Regional Office. The water level data will also be kept as a written record at the site. The remediation system will be equipped with an electronic monitor, which automatically records the time and date of every system shutdown event. If more than three (3) float -activated shutdown events are recorded during a consecutive 30 day period, the system flow rate will be reduced by 10% of its rate at the time. If the situation persists after the flow rate has been reduced, further reductions in the flow rate may be required. 17. The groundwater recovery, treatment and disposal system shall be inspected weekly for the duration of the permit. If it is determined that the system is malfunctioning, all repairs should be made as soon as possible and reported to the regional groundwater supervisor at the Winston-Salem Regional Office within 48 hours of the determination. 18. The groundwater treatment system shall consistently achieve Class GA Groundwater Standards in the treated effluent, as outlined under Title 15A, Subchapter 2L, Section .0202(g), prior to discharge in the infiltration gallery. The treated water discharged into the infiltration gallery must not violate the Class GA Groundwater Quality Standards for any constituent beyond the Compliance Boundary, nor cause the migration of contamination in unaffected areas. If the treatment system fails to consistently achieve this standard, additional treatment units or changes in operational methods, may be required. V . INSPECTIONS 1. Adequate inspection, maintenance and cleaning shall be provided by the Permittee to insure proper operation of the subject facilities. 2. The Permittee or his designee shall inspect the groundwater recovery and treatment 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 three years from the date of the inspection and shall be made available to the Division of Environmental Management or other permitting authority, upon request. 3. Any duly authorized officer, employee, or representative of the Division of Environmental Management may, upon presentation of credentials, enter and inspect any property, premises or place on or related to the disposal 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 maintained under the terms and conditions of this permit, and may obtain samples of groundwater, surface water, or leachate. 6 VI.
