Delay of repair is allowed for any of the conditions specified below.The Permittee shall maintain a record of the facts that explain any delay of repairs and, where appropriate, why the repair was technically infeasible without a process unit shutdown. i. Delay of repair of equipment for which leaks have been detected is allowed if repair within 15 days after a leak is detected is technically infeasible without a process unit or affected facility shutdown. Repair of this equipment shall occur as soon as practical,but no later than the end of the next process unit shutdown.However, delay of repair beyond a process unit shutdown will be allowed for a valve if valve assembly replacement is necessary during the process unit shutdown, and valve assembly supplies have been depleted, and valve assembly supplies had been sufficiently stocked before the supplies were depleted.Delay of repair beyond the second process unit shutdown will not be allowed unless the third process unit shutdown occurs sooner than six months after the first process unit shutdown. ii. Delay of repair of equipment for which leaks have been detected is allowed for equipment that is isolated from the process and that does not remain in VDC service, iii. Delay of repair for valves and connectors is also allowed if: (A)The Permittee determines that emissions of purged material resulting from immediate repair would be greater than the fugitive emissions likely to result from delay of repair,and (B) When repair procedures are effected, the purged material cannot be collected and destroyed or reused in the process. iv. Delay of repair for pumps is also allowed if repair requires replacing the existing seal design with a new system that the Permittee has determined under a quality improvement program (Sections 2.2 B.2,bb through 2.2 B.2.gg,below)will provide better performance,or the repair is completed as soon as practical,but not later than b months after the leak was detected and one of the following is used; (A)A dual mechanical seal system; (B) A pump that meets has no external shaft penetrating the pump housing; or (C) A system that routes emissions to a process or a fuel gas system or a closed vent system and control device; Valves in Gas/Vapor%kht Liguid Service[1SA NCAC 02Q .0508(f)] 1.

The Permittee shall keep a record of the monitoring schedule for each process unit. m. The Permittee may choose to subdivide the valves in the group of process units and apply the monitoring frequency provisions to each subgroup. If the Permittee subdivides the valves in the group of process units,then the following provisions apply. i. The overall performance of total valves in the group of process units to be subdivided shall be less than two percent leaking valves_ ii. The initial assignment or subsequent reassignment of valves to subgroups shall be governed as follows, (A)The Permittee shall determine which valves are assigned to each subgroup,Valves with less than one year of monitoring data or valves not monitored within the last twelve months must be placed initially into the most frequently monitored subgroup until at least one year of monitoring data have been obtained. (B)Any valve or group of valves can be reassigned from a less frequently monitored subgroup to a more frequently monitored subgroup provided that the valves to be reassigned were monitored during the most recent monitoring period for the less frequently monitored subgroup. The monitoring results must he included with that less frequently monitored subgroup's associated percent leaking valves calculation for that monitoring event. (C) Any valve or group of valves can be reassigned from a more frequently monitored subgroup to a less frequently monitored subgroup provided that the valves to be reassigned have not leaked for the period of the less frequently monitored subgroup(e.g., for the last 12 months,if the valve or group of valves is to be reassigned to a subgroup being monitored annually). Non-repairable valves may not be reassigned to a less frequently monitored subgroup. id. The Permittee shall determine every six months if the overall performance of total valves in the applicable process unit or group of process units is less than two percent leaking valves and so indicate the performance in the next periodic report.If the overall performance of total valves in the applicable process unit or group of process units is two percent leaking valves or greater,the Permittee shall no longer subgroup and shall revert to the program required in Section 2.2 B.2,p,for that group of process units.The Permittee can again elect to comply with the valve subgrouping procedures if future overall performance of total valves in the process unit or group of process units is again less than two percent.

Repair of this equipment shall occur as soon as practical,but no later than the end of the next process unit shutdown.However, delay of repair beyond a process unit shutdown will be allowed for a valve if valve assembly replacement is necessary during the process unit shutdown, and valve assembly supplies have been depleted, and valve assembly supplies had been sufficiently stocked before the supplies were depleted.Delay of repair beyond the second process unit shutdown will not be allowed unless the third process unit shutdown occurs sooner than six months after the first process unit shutdown. ii. Delay of repair of equipment for which leaks have been detected is allowed for equipment that is isolated from the process and that does not remain in VDC service, iii. Delay of repair for valves and connectors is also allowed if: (A)The Permittee determines that emissions of purged material resulting from immediate repair would be greater than the fugitive emissions likely to result from delay of repair,and (B) When repair procedures are effected, the purged material cannot be collected and destroyed or reused in the process. iv. Delay of repair for pumps is also allowed if repair requires replacing the existing seal design with a new system that the Permittee has determined under a quality improvement program (Sections 2.2 B.2,bb through 2.2 B.2.gg,below)will provide better performance,or the repair is completed as soon as practical,but not later than b months after the leak was detected and one of the following is used; (A)A dual mechanical seal system; (B) A pump that meets has no external shaft penetrating the pump housing; or (C) A system that routes emissions to a process or a fuel gas system or a closed vent system and control device; Valves in Gas/Vapor%kht Liguid Service[1SA NCAC 02Q .0508(f)] 1.

The Permittee shall keep a record of the monitoring schedule for each process unit. m. The Permittee may choose to subdivide the valves in the group of process units and apply the monitoring frequency provisions to each subgroup. If the Permittee subdivides the valves in the group of process units,then the following provisions apply. i. The overall performance of total valves in the group of process units to be subdivided shall be less than two percent leaking valves_ ii. The initial assignment or subsequent reassignment of valves to subgroups shall be governed as follows, (A)The Permittee shall determine which valves are assigned to each subgroup,Valves with less than one year of monitoring data or valves not monitored within the last twelve months must be placed initially into the most frequently monitored subgroup until at least one year of monitoring data have been obtained. (B)Any valve or group of valves can be reassigned from a less frequently monitored subgroup to a more frequently monitored subgroup provided that the valves to be reassigned were monitored during the most recent monitoring period for the less frequently monitored subgroup. The monitoring results must he included with that less frequently monitored subgroup's associated percent leaking valves calculation for that monitoring event. (C) Any valve or group of valves can be reassigned from a more frequently monitored subgroup to a less frequently monitored subgroup provided that the valves to be reassigned have not leaked for the period of the less frequently monitored subgroup(e.g., for the last 12 months,if the valve or group of valves is to be reassigned to a subgroup being monitored annually). Non-repairable valves may not be reassigned to a less frequently monitored subgroup. id. The Permittee shall determine every six months if the overall performance of total valves in the applicable process unit or group of process units is less than two percent leaking valves and so indicate the performance in the next periodic report.If the overall performance of total valves in the applicable process unit or group of process units is two percent leaking valves or greater,the Permittee shall no longer subgroup and shall revert to the program required in Section 2.2 B.2,p,for that group of process units.The Permittee can again elect to comply with the valve subgrouping procedures if future overall performance of total valves in the process unit or group of process units is again less than two percent. The overall performance of total valves in the applicable process unit or group of process units shall be calculated as a weighted average of the percent leaking valves of each subgroup according to following equation: n �(%VL; xli} %V10 '�— [=i R Y i=1 Where: o/oV[.o=Overall performance of total valves in the applicable process unit or group of process units %VLi =Percent leaking valves in subgroup i, most recent value Vi =Number of valves in subgroup i n =Number of subgroups. iv.

VL = Number of valves found leaking, excluding non-repairable valves and including those valves found whose repair was not confirmed with both post leak repair monitoring and periodic monitoring. VT = The sum of the total number of valves monitored. o. When determining monitoring frequency for each process unit or valve subgroup subject to monthly, quarterly,or semiannual monitoring frequencies,the percent leaking valves shall be the arithmetic average of the percent leaking valves from the last two monitoring periods. When determining monitoring frequency for each process unit or valve subgroup subject to annual or biennial (once every 2 years) monitoring frequencies,the percent leaking valves shall be the arithmetic average of the percent leaking valves from the last three monitoring periods. i. Non-repairable valves shall be included in the calculation of percent leaking valves the first time the valve is identified as leaking and non-repairable. Otherwise, a number of non-repairable valves (identified and included in the percent leaking valves calculation in a previous period) up to a maximum of one percent of the total number of valves in VOC service at a process unit may be excluded from calculation of percent leaking valves for subsequent monitoring periods. ii. If the number of non-repairable valves exceeds one percent of the total number of valves in regulated material service at a process unit or affected facility,the number of non-repairable valves exceeding one percent of the total number of valves in regulated material service shall be included in the calculation of percent leaking valves. p. If a leak is determined,then the leak shall he repaired. After a leak has been repaired,the valve shall be monitored at least once within the first three months after its repair. i. This monitoring is in addition to the monitoring required to satisfy the definition of repaired and first attempt at repair. The monitoring shall be conducted to determine whether the valve has resumed leaking. ii. Periodic monitoring may be used to satisfy this if the timing of the monitoring period coincides with the time specified. Alternatively, other monitoring may be performed to satisfy the requirement regardless of whether the timing of the monitoring period for periodic monitoring coincides with the time above. iii. If a leak is detected by monitoring that is conducted after leak repair,the Permittee shall: (A)Use periodic monitoring to satisfy the requirement above, then the valve shall be counted as a leaking valve, or (B)If the Permittee elected to use other monitoring, prior to the periodic monitoring, to satisfy the above requirement, then the valve shall be counted as a leaking valve unless it is repaired and shown by periodic monitoring not to be leaking.
