Okla. Admin. Code § 252:100-39-15

Current through Vol. 42, No. 1, September 16, 2024

Section 252:100-39-15 - Petroleum refinery equipment leaks

(a)Definitions. The following words and terms, when used in this Section, shall have the following meaning, unless the context clearly indicates otherwise.

(1)"Component" means any piece of equipment which has the potential to leak VOCs when tested in the manner described in EPA Test Method 21 of 40 CFR Part 60. These sources include, but are not limited to, pumping seals, compressor seals, seal oil degassing vents, pipeline valves, flanges and other connections, pressure relief devices, process drains, and open ended pipes. Excluded from these sources are valves which are not externally regulated.

(2)"Gas service" means any equipment which processes, transfers or contains a VOC or mixture of VOCs in the gaseous phase.

(3)"Leaking component" means a component which has a VOC concentration exceeding 10,000 ppmv when tested according to the provisions in 252:100-39-15(e).

(4)"Liquid service" means any equipment which processes, transfers or contains a VOC or mixture of VOCs in the liquid phase.

(5)"Valves not externally regulated" means valves that have no external controls, such as in-line check valves.

(b)Applicability.

(1) This Section applies to all petroleum refineries located in Tulsa County and Oklahoma County.

(2) VOCs with vapor pressures less than 0.0435 psia (0.3 kilopascals (kPa)) under actual storage conditions are exempt from 252:100-39-15. (Effective 2-12-90.)

(c)Standards and operating requirements.

(1) The owner or operator of a petroleum refinery subject to this Section shall:

(A) develop and conduct a monitoring program consistent with the provisions in 252:100-39-15(d) and 252:100-39-15(f);

(B) record all leaking components and place an identifying tag on each component consistent with the provisions in 252:100-39-15(f) (3);

(C) repair and retest the leaking components as soon as possible but no later than 15 days after the leak is found;

(D) identify all leaking components which cannot be repaired until the unit is shutdown for turnaround; and,

(E) assure all lines or pipes terminating with a valve are sealed with a second valve, a blind flange, a plug or a cap.

(2) The Division Director mayrequire the owner or operator to take appropriate remedial action, including early unit turnaround, based on the number and severity of tagged leaks awaiting repair.

(3) Pipeline valves and pressure relief valves in gas service shall be marked in some manner that will be readily obvious to both petroleum refinery or contract personnel performing monitoring and the DEQ.

(d)Compliance schedule. The owner or operator of a petroleum refinery shall submit to the Division Director a monitoring program by July 30, 1981. This program shall contain, at a minimum, a list of the refinery units and the quarter in which they will be monitored, a copy of the log book format, and the make and model of the monitoring equipment to be used. In no case shall a monitoring contract relieve the owner or operator of a petroleum refinery of the responsibility for compliance with this Section.

(e)Testing and monitoring procedures. Testing and calibration procedures to determine compliance with this Section must be consistent with EPA Test Method 21 of 40 CFR Part 60.

(f)Monitoring.

(1) The owner or operator of a petroleum refinery shall conduct a monitoring program consistent with the following provisions. The owner or operator shall:

(A) monitor yearly by the methods referenced in 252:100-39-15(e) all pump seals, pipeline valves in liquid service, and process drains;

(B) monitor quarterly by the methods referenced in 252:100-39-15 -(e) all compressor seals, pipeline valves in gas service, and pressure relief valves in gas service;

(C) monitor weekly by visual methods all pump seals;

(D) monitor within 24 hours any pump seal from which VOC liquids are observed dripping;

(E) monitor any relief valve within 24 hours after it has vented to the atmosphere; and,

(F) monitor immediately after repair any component that was found leaking.

(2) Pressure relief devices that are connected to an operating flare header, vapor recovery devices, 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 that 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 which shall contain, at a minimum:

(A) the name of the process unit where the component is located;

(B) the type of component (e.g., valve, seal);

(C) the tag number of the component, if not repaired immediately on discovery;

(D) the date on which a leaking component is discovered;

(E) the date on which a leaking component is repaired;

(F) the date and instrument reading of the recheck procedure after a leaking component is repaired;

(G) the date of the calibration of the monitoring instrument which shall be made available for inspection on request;

(H) those leaks that cannot be repaired until turnaround; and,

(I) the total number of components checked and the total number of components found leaking.

(2) The monitoring log shall be retained on site by the owner or operator for at least two years after the date on which the record was made or the report prepared.

(3) The monitoring log shall be made available for inspection at any reasonable time and copies of the log shall be provided to the Division Director, upon written request of the AQD.

(h)Reporting. The owner or operator of a petroleum refinery shall:

(1) submit a report to the Division 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 all monitoring and, with the exception of those leaking components listed in 252:100-39-15(h)(1), all repairs were performed as stipulated in the monitoring program.
