Seymour Johnson AFB is required to notify the Division in writing in the event the permitted facility is sold or closed. SECTION B: OPERATION AND MAINTENANCE of POLLUTION CONTROLS 1. Proper Operation and Maintenance Seymour Johnson AFB shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are owned and/or operated by Seymour Johnson AFB to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by Seymour Johnson AFB only when the operation is necessary to achieve compliance with the conditions of this permit. 2. Need to Halt or Reduce not a Defense It shall not be a defense for Seymour Johnson AFB in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit. Part V Page 3 of 6 PERMIT NO.NCS000335 3. Bypassing of Stormwater Control Facilities Bypass is prohibited and the Director may take enforcement action against Seymour Johnson AFB for bypass unless: a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities, retention of stormwater or maintenance during normal periods of equipment downtime or dry weather. This condition is not satisfied if adequate backup controls should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and C. Seymour Johnson AFB submitted notices as required under Section E of this Part. If the Director determines that it will meet the three conditions listed above, the Director may approve an anticipated bypass after considering its adverse effects. SECTION C: MONITORING AND RECORDS 1. Representative Sampling When required herein, stormwater samples collected and measurements taken shall be characteristic of the volume and nature of the permitted discharge. Analytical stormwater sampling shall be performed during a representative storm event. These samples shall be taken on a day and time that is characteristic of the discharge. Where appropriate, all stormwater samples shall be taken before the discharge joins or is diluted by any other waste stream, body of water, or substance. When specified herein, monitoring points established in this permit shall not be changed without notification to and approval of the Director. If a facility has multiple discharge locations with substantially identical stormwater discharges that are required to be sampled, Seymour Johnson AFB may petition the Director for representative outfall status. If it is established that the stormwater discharges are substantially identical and Seymour Johnson AFB is granted representative outfall status, then sampling requirements may be performed at a reduced number of outfalls. 2. Flow Measurements Where required, appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. 3. Test Procedures Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136. Part V Page 4 of 6 PERMIT NO.NCS000335 To meet the intent of the monitoring required by this permit, all test procedures must produce minimum detection and reporting levels and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. 4. Inspection and Entry Seymour Johnson AFB shall allow the Director, or an authorized representative (including an authorized contractor acting as a representative of the Director), or in the case of a facility which discharges through a municipal separate storm sewer system, an authorized representative of a municipal operator or the separate storm sewer system receiving the discharge, upon the presentation of credentials and other documents as may be required by law, to; a.

As required by the Act, analytical data shall not be considered confidential. Knowingly making any false statement on any such report may result in the imposition of criminal penalties as provided for in NCGS 143-215.613 or in Section 309 of the Federal Act. 6. Bypass a. Anticipated bypass. If Seymour Johnson AFB knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and effect of the bypass. b. Unanticipated bypass. Seymour Johnson AFB shall submit notice within 24 hours of becoming aware of an unanticipated bypass. 7. Other Noncompliance Seymour Johnson AFB shall report all instances of noncompliance not reported under 24 hour reporting at the time monitoring reports are submitted. Part V Page 5 of 6 PERMIT NO.NCS000335 8. Anticipated Noncompliance Seymour Johnson AFB shall give notice to the Director as soon as possible of any planned changes at the permitted facility which may result in noncompliance with the Permit requirements. 9. Planned Changes Seymour Johnson AFB shall give notice to the Director as soon as possible of any planned changes at the permitted facility which could significantly alter the nature or quantity of pollutants discharged. This notification requirement includes pollutants which are not specifically listed in the Permit or subject to notification requirements under 40 CFR Part 122.42 (a). 10. Non-Stormwater Discharges If the storm event monitored in accordance with this Permit coincides with a non-stormwater discharge, Seymour Johnson AFB shall separately monitor all parameters as required under the non-stormwater discharge permit and provide this information with the stormwater discharge monitoring report. 11. Discharge Monitoring Reports Seymour Johnson AFB shall retain all monitoring information for a period of at least 5 years from the date of the sample, measurement, report or application. This period may be extended by request of the Director at any time. When no discharge has occurred from the facility during the report period, Seymour Johnson AFB indicate "NO FLOW" as per NCAC T15A 0213 .0506. Seymour Johnson AFB shall record the required qualitative monitoring observations on the SDO Qualitative Monitoring Report form provided by the Division, and shall retain the completed forms on site. Visual monitoring results should not be submitted to the Division, except upon DEQ's specific requirement to do so.

A single storm event may have a period of no precipitation of up to 10 hours. For example, if it rains but stops before producing any collectable discharge, a sample may be collected if the next rain producing a discharge begins within 10 hours. 27. Representative Outfall Status When it is established that the discharge of stormwater runoff from a single outfall is representative of the discharges at multiple outfalls, the DEMLR may grant representative outfall status. Representative outfall status allows Seymour Johnson AFB to perform analytical monitoring at a reduced number of outfalls. 28.

An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment or control facilities, inadequate treatment or control facilities, lack of preventive maintenance, or careless or improper operation. 44. Vegetative Buffer Vegetative buffer has the same meaning as in 15A NCAC 02H .1002(22) and means an area of natural or established vegetation directly adjacent to surface waters through which stormwater runoff flows in a diffuse manner to protect surface waters from degradation due to development activities. 45. Vegetative Conveyance Vegetative conveyance means a permanent, designed waterway lined with vegetation that is used to convey stormwater runoff at a non-erosive velocity within or away from a developed area. As used herein, "conveyance system" shall not include a stormwater collection system. 46.
