For the Beaumont-Port Arthur, Bexar County, Dallas-Fort Worth,
El Paso, and Houston-Galveston-Brazoria areas, as defined in §115.10
of this title (relating to Definitions), no person shall operate a
petroleum refinery; a synthetic organic chemical, polymer, resin,
or methyl-tert-butyl ether manufacturing process; or a natural gas/gasoline
processing operation, as defined in §115.10 of this title, without
complying with the following requirements.
(1) Except as provided in paragraph (2) of this section,
no component may be allowed to have a volatile organic compound (VOC)
leak for more than 15 calendar days after the leak is found that meets
the following:
(A) for all components except pump seals and compressor
seals, a screening concentration greater than 500 parts per million
by volume (ppmv) above background as methane, or the dripping or exuding
of process fluid based on sight, smell, or sound;
(B) for pump seals and compressor seals, a screening
concentration greater than 10,000 ppmv above background as methane,
or the dripping or exuding of process fluid based on sight, smell,
or sound; and
(C) if the owner or operator elects to use the alternative
work practice in §115.358 of this title (relating to Alternative
Work Practice), any leak detected as defined in §115.358 of this
title, including any leak detected using the alternative work practice
on a component that is subject to the requirements of this division
(relating to Fugitive Emission Control in Petroleum Refining, Natural
Gas/Gasoline Processing, and Petrochemical Processes in Ozone Nonattainment
Areas) but not specifically selected for alternative work practice
monitoring.
(2) A first attempt at repair must be made no later
than five calendar days after the leak is found and the component
must be repaired no later than 15 calendar days after the leak is
found, unless the repair of the component would require a unit shutdown
that would create more emissions than the repair would eliminate.
A component in gas/vapor or light liquid service is considered to
be repaired when it is monitored with an instrument using Method 21
in 40 Code of Federal Regulations (CFR) Part 60, Appendix A-7 (October
17, 2000) and shown to no longer have a leak after adjustments or
alterations to the component. A component in heavy liquid service
is considered to be repaired when it is inspected by audio, visual,
and olfactory means and shown to no longer have a leak after adjustments
or alterations to the component. For any component that the owner
or operator monitors using the alternative work practice in §115.358
of this title, the component is considered repaired when the component
is demonstrated to no longer have a leak after adjustments or alterations
to the component by either screening using an optical gas imaging
instrument as specified in §115.358 of this title or by the normal
monitoring method required under this division. If the repair of a
component within 15 days after the leak is detected would require
a process unit shutdown that would create more emissions than the
repair would eliminate, the repair may be delayed until the next scheduled
process unit shutdown.
(A) Delay of repair beyond a process unit shutdown
will be allowed for a component if that component is isolated from
the process and does not remain in VOC service.
(B) Valves that can be safely repaired without a process
unit shutdown may not be placed on the shutdown list.
(C) Delay of repair will be allowed for pumps, compressors,
or agitators if the repair is completed as soon as practicable, but
not later than six months after the leak was detected, and the repair
requires replacing the existing seal design with:
(i) a dual mechanical seal system that includes a barrier
fluid system;
(ii) a system that is designed with no externally actuated
shaft penetrating the housing; or
(iii) a closed-vent system and control device that
meets the requirements of §115.122(a)(2) of this title (relating
to Control Requirements).
(3) All leaking components, as defined in paragraph
(1) of this section, that cannot be repaired until a process unit
shutdown must be identified for such repair by tagging. The executive
director may require an early process unit shutdown or other appropriate
action based on the number and severity of tagged leaks awaiting a
process unit shutdown.
(4) No valves may be installed or operated at the end
of a pipe or line containing VOC unless the pipe or line is sealed
with a second valve, a blind flange, or a tightly-fitting plug or
cap. The sealing device may be removed only while a sample is being
taken or during maintenance operations, and when closing the line,
the upstream valve must be closed first.
(5) Construction of new and reworked piping, valves,
and pump and compressor systems must conform to applicable American
National Standards Institute, American Petroleum Institute, American
Society of Mechanical Engineers, or equivalent codes.
(6) New and reworked underground process pipelines
must contain no buried valves such that fugitive emission monitoring
is rendered impractical.
(7) To the extent that good engineering practice will
permit, new and reworked components must be so located to be reasonably
accessible for leak-checking during plant operation. A difficult-to-monitor
component is a component that cannot be inspected without elevating
the monitoring personnel more than two meters above a permanent support
surface or that requires a permit for confined space entry as defined
in 29 CFR §1910.146 (December 1, 1998). Difficult-to-monitor
components must be identified in a list to be made available upon
request as specified in §115.356(5) of this title (relating to
Recordkeeping Requirements).
(8) New and reworked piping connections must be welded,
flanged, or consist of pressed and permanently formed metal-to-metal
seals. Screwed connections are permissible only on new piping smaller
than two inches in diameter.
(9) For pressure relief valves installed in series
with a rupture disk, pin, second relief valve, or other similar leak-tight
pressure relief component, a pressure gauge or an equivalent device
or system must be installed between the relief valve and the other
pressure relief component to monitor for leakage past the first component.
When leakage is detected past the first component, that component
must be repaired or replaced at the earliest opportunity, but no later
than the next process unit shutdown. Equivalent devices or systems
must be identified in a list to be made available upon request as
specified in §115.356(5) of this title and must have been approved
by the methods required by §115.353 of this title (relating to
Alternate Control Requirements).
(10) Any petroleum refinery; synthetic organic chemical,
polymer, resin, or methyl-tert-butyl ether manufacturing process;
or natural gas/gasoline processing operation in the Houston-Galveston-Brazoria
area in which a highly-reactive volatile organic compound, as defined
in §115.10 of this title, is a raw material, intermediate, final
product, or in a waste stream is subject to the requirements of Subchapter
H of this chapter (relating to Highly-Reactive Volatile Organic Compounds)
in addition to the applicable requirements of this division.
