Current through Register Vol. 63, No. 3, March 1, 2024
(1)
All persons operating petroleum refineries must comply with this section
concerning leaks:
(a) The owner or operator
of a petroleum refinery complex, upon detection of a leaking component, which
has a VOC concentration exceeding 10,000 ppm when tested in the manner
described below must:
(A) Include the leaking
component on a written list of scheduled repairs; and
(B) Repair and retest the component within 15
days.
(b) Except for
safety pressure relief valves, no owner or operator of a petroleum refinery may
install or operate a valve at the end of a pipe or line containing VOCs unless
the pipe or line is sealed with a second valve, a blind flange, a plug, or a
cap. The sealing device may be removed only when a sample is being taken during
maintenance operations;
(c)
Pipeline valves and pressure relief valves in gaseous VOC service must be
marked in some manner that will be readily obvious to both refinery personnel
performing monitoring and DEQ.
(2) Testing Procedures: Testing and
calibration procedures to determine compliance with this rule must be done in
accordance with EPA Method 21.
(3)
Monitoring, Recordkeeping, Reporting:
(a) The
owner or operator of a petroleum refinery must maintain, as a minimum, records
of all testing conducted under this rule; plus records of all monitoring
conducted under subsections (b) and (c);
(b) The owner or operator of a petroleum
refinery subject to this rule must:
(A)
Monitor yearly by the methods referenced in section (2) all:
(i) Pump seals;
(ii) Pipeline valves in liquid service;
and
(iii) Process drains.
(B) Monitor quarterly by the
methods referenced in section (2) all:
(i)
Compressor seals;
(ii) Pipeline
valves in gaseous service; and
(iii) Pressure relief valves in gaseous
service.
(C) Monitor
weekly by visual methods all pump seals;
(D) Monitor immediately any pump seal from
which 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 of any
component that was found leaking.
(c) Pressure relief devices which are
connected to an operating flare header, vapor recovery device, inaccessible
valves, storage tank valves, or valves that are not externally regulated are
exempt from the monitoring requirements in subsection (b);
(d) The owner or operator of a petroleum
refinery, upon the detection of a leaking component, must affix a weatherproof
and readily visible tag bearing an identification number and the date the leak
is located to the leaking component. This tag must remain in place until the
leaking component is repaired;
(e)
The owner or operator of a petroleum refinery, upon the completion of each
yearly and/or quarterly monitoring procedure, must:
(A) Submit a report to DEQ on the 15th day of
January, April, July, and September, listing the leaking components that were
located but not repaired within the required time limit in subsection
(1)(a);
(B) Submit a signed
statement attesting to the fact that, with the exception of those leaking
components listed in paragraph (A), all monitoring and repairs were performed
as stipulated.
(f) The
owner or operator of a petroleum refinery must maintain a leaking component
monitoring log that contains, at a minimum, the following data:
(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;
(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) A record of the
calibration of the monitoring instrument;
(H) Those leaks that cannot be repaired until
turnaround, exceptions to the 15-day requirement of paragraph (1)(a)(B);
and
(I) The total number of
components checked and the total number of components found leaking.
(g) Copies of all records and
reports required by this section must be retained by the owner or operator for
a minimum of five years after the date on which the record was made or the
report submitted;
(h) Copies of all
records and reports required by this section must immediately be made available
to DEQ upon verbal or written request at any reasonable time;
(i) DEQ may, upon written notice, modify the
monitoring, recordkeeping and reporting requirements.
