The Permittee shall maintain an inspection log that includes, at a minimum, the date and time of inspection, observations made, and any maintenance, repairs, or corrective actions taken. The Permittee shall maintain this inspection log for a period of five years from the date of the inspection, and this log shall be made available to the Division upon request. [15A NCAC 02T .0108(b)] 3. Any duly authorized Division representative may, upon presentation of credentials, enter and inspect any property, premises or place on or related to the reclaimed water generation and utilization facilities permitted herein at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records required to be maintained under the terms and conditions of this permit, and may collect groundwater, surface water or leachate samples. [G.S. 143-215.1] 1. Failure to comply with the conditions and limitations contained herein may subject the Permittee to an enforcement action by the Division in accordance with North Carolina General Statutes 143-215.6A to 143-215.6C. [G.S. 143-215.6A to 143-215.6C] 2. This permit shall become voidable if the permitted facilities are not constructed in accordance with the conditions of this permit, the Division approved plans and specifications, and other supporting documentation. [15A NCAC 02T .0110] 3. This permit is effective only with respect to the nature and volume of wastes described in the permit application, Division approved plans and specifications, and other supporting documentation. No variances to applicable rules governing the construction or operation of the permitted facilities are granted, unless specifically requested and approved in this permit pursuant to 15A NCAC 02T .0105(n). [G.S. 142-215.1] 4. The Division accepts the data -based design flow rate of 240 gallons per day per home or lot (GPD/home or lot) for the users served by this facility. Regardless of the adjusted daily wastewater design flow rate, at no time shall wastewater flows exceed the limits defined in this permit for the subject facility, or exceed the sewer capacity downstream of any new sewer extension or service connection(s). The Permittee shall report the actual (i.e., measured) monthly average amount of wastewater flow contributed per unit (GPD/home or lot) for the 12 months prior to permit renewal. If any of these actual monthly averages are within 20% of the 194,490 GPD, the Permittee shall re-evaluate the approved value using the methodology applied to determine the approved flow rate of 240 GPD/lot or home, and submit this information within 18 months of permit issuance. The Division may change the daily wastewater design flow rate for connections to the system at that time, and upon each renewal cycle, pending an evaluation of the submitted flow information. [15A NCAC 02T .0114(f)] 5. The Permittee shall retain the Division's written approval of any authorized adjusted daily design flow rate for the life of the facility, and shall transfer said written approval to any future Permittee.
