SCHEDULES [please review the entire permit for reporting, monitoring, and other on -going activities] M-- 1. No later than six (6) months prior to the expiration of this permit, the Permittee shall request renewal of this permit on official Division form(s). Upon receipt of the request, the Division will review the adequacy of the facilities described therein, and if warranted, will extend the permit for such period of time and under such conditions and limitations as it may deem appropriate. Please note that Rule 15A NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal application. 2. The subject wastewater treatment and disposal facilities shall be connected to an operational publicly owned wastewater collection system within 180 days of its availability to the subject facilities, if the subject wastewater treatment or disposal facilities are in noncompliance with the terms and conditions of this non -discharge permit or the governing statutes or regulations. Prior to the initiation of these connection activities, appropriate approval must be received from this Division. If The Capital Area YMCA determines that utilization of the secondary spray field areas are necessary, a permit amendment must be submitted to the Division for review. Prior to these fields being used for spray irrigation, they shall be fenced. H. PERFORMANCE STANDARDS The surface irrigation facilities shall be effectively maintained and operated at all times so that there is no discharge to the surface waters, nor any contravention of groundwater or surface water standards. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to adequately assimilate the wastewater, the Permittee shall take immediate corrective actions including those actions that may be required by the 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 ground or surface waters resulting from the operation of this facility. 3. All wells that are constructed for purposes of groundwater monitoring shall be constructed in accordance with 15A NCAC 02C .0108 (Standards of Construction for Wells Other than Water Supply) and any other state and local laws and regulations pertaining to well construction. 4. The wastewater collection facilities shall be properly maintained and operated at all times. The Permittee shall maintain compliance with an individual system -wide collection system permit for the operation and maintenance of these facilities as required by 15A NCAC 02T .0400. If an individual permit is not required, the following performance criteria shall be met as provided in 15A NCAC 02T .0403 a.
