          (2)  Pressure relief devices which are connected to an operating flare header, vapor recovery device, inaccessible valves, storage tank valves, and valves that are not externally regulated are exempt from the monitoring requirements in paragraph (1) of this subsection. Provided, however, such inaccessible valves will be monitored during annual shutdown.
          (3)  The owner or operator of a petroleum refinery, upon the detection of a leaking component, as defined in 252:100-39-15(c)(1)(C), which is not repaired on discovery shall affix a weatherproof and readily visible tag, bearing an identification number and the date the leak is located, to the leaking component. This tag shall remain in place until the leaking component is repaired.

     (g)  Recordkeeping.
          (1)  The owner or operator of a petroleum refinery shall maintain a leaking components monitoring log as specified in 252:100-39-15(c)(1)(C) which shall contain, at a minimum, the following data:

          (3)  Copies of the monitoring log shall be made available to the  Executive Director, upon written request, at any reasonable time.

     (h)  Reporting.  The owner or operator of a petroleum refinery, upon the completion of each monitoring procedure, shall:
          (1)  submit a report to the  Executive Director by the 30th day following the end of each calendar quarter that lists all leaking components that were located during the previous quarter but not repaired within 15 days, all leaking components awaiting unit turnaround, and the total number of components found leaking; and,
          (2)  submit a signed statement with the report attesting to the fact that, with the exception of those leaking components listed in 252:100-39-15(h)(1), all monitoring and repairs were performed as stipulated in the monitoring program.

252:100-39-16.  Refinery process unit turnaround

     (a)  Definition.  "Turn around" means the planned procedure of shutting down a unit, inspecting and repairing it and restarting it.

     (b)  Procedures required.  For the shutdown, purging and blowdown operation of any processing petroleum refinery processing unit the following procedures are required:
          (1)  Recovery of volatile organic compounds (VOC) shall be accomplished during the shutdown or turnaround to a process unit pressure compatible with the flare or vapor system pressure.  The unit will then be purged or flushed with a suitable material such as steam, water or nitrogen to a flare or vapor recovery system.  The unit shall not be vented to the atmosphere until pressure is reduced to less than 5 psig through control devices.
          (2)  Except where inconsistent with the "Minimum Federal Safety Standards for the Transportation of Natural and Other Gas by Pipeline," or any State of Oklahoma regulatory agency, no person shall emit organic gases to the atmosphere from a vapor recovery blowdown system unless these gases are burned by smokeless flares, or an equally effective control device as approved by the  Executive Director.
          (3)  At least fifteen days prior to a scheduled turnaround, a written notification shall be submitted to the  Executive Director. As a minimum, the notification shall indicate the unit to be shutdown, the date of shutdown, and the approximate quantity of hydrocarbons to be emitted to the atmosphere.
          (4)  Scheduled refinery unit turnaround may be accomplished without the controls specified in 252:100-39-16(b)(1) and 252:100-39-16(b)(2) during non-oxidant seasons provided the notification to the  Executive Director as required in 252:100-39-16(b)(3), specifically contains such a request for such an exemption.  Non-oxidant season is understood to be between the months of October and April.

          (2)  "Hotwell" means the tank at the bottom of the barometer leg in a barometric condenser system to receive the water, condensate and entrained hydrocarbons generated by the barometric condenser.

     (b)  Requirements.  Noncondensable volatile organic compounds from the following equipment shall be incinerated or reduced by 90 percent of what would be emitted from the following vacuum producing system:
          (1)  steam ejectors with barometric condensers;
          (2)  steam ejectors with surface condensers; or,
          (3)  mechanical vacuum pumps.

     (c)  Hotwells and accumulators.
          (1)  Hot wells and accumulators shall be covered and the noncondensable vapors shall be vented to a fire-box or incinerator.
          (2)  The presence of a pilot flame shall be monitored using a thermocouple or any other equivalent device to detect the presence of a flame.  (Effective February 12, 1990)

     (d)  Compliance.  Compliance shall be determined in accordance with the provision of the CTG document (EPA 450/2-77-025).  Test reports and maintenance records will be maintained for two years.  If emission testing is required, the appropriate test method(s) selected from EPA Reference Methods 1 through 4, 21, and/or 25, will be utilized.
