|(a) Applicability. This section applies to certain
authorized oil and gas handling or production facilities or sites,
and authorizes emissions from planned maintenance, startup, and shutdown
(MSS) facilities and activities, and any associated emission capture
and control facilities, if all of the applicable requirements of this
section are met.
(1) This section does not apply to oil and gas handling
or production facilities or sites authorized under §106.352(a)
- (k) of this title (relating to Oil and Gas Handling and Production
Facilities), subsections (a) - (k) of the non-rule Air Quality Standard
Permit for Oil and Gas Handling and Production Facilities, §106.355
of this title (relating to Pipeline Metering, Purging, and Maintenance),
or Subchapter U of this chapter (relating to Tanks, Storage, and Loading).
(2) This section may not be used to supersede an existing
authorization for planned MSS under this chapter or §116.620
of this title (relating to Installation and/or Modification of Oil
and Gas Facilities) unless any previously represented emission control
methods, techniques, and devices remain in use and there is no resulting
increase in hourly emissions.
(b) Activities. Planned MSS activities and facilities
authorized by this section include the following:
(1) engine, compressor, turbine, and other combustion
(2) repair, adjustment, calibration, lubrication, and
cleaning of site process equipment;
(3) replacement of piping components, pneumatic controllers,
boiler refractories, wet and dry seals, meters, instruments, analyzers,
screens, and filters;
(4) turbine or engine component swaps;
(5) piping used to bypass a facility during maintenance;
(6) planned MSS activities with the same character
and quantity of emissions as those listed in paragraphs (1) - (5)
of this subsection;
(7) pigging and purging of piping;
(9) emptying, purging, degassing, or refilling of process
equipment, storage tanks and vessels (except landing floating roof
tanks for convenience purposes), if subparagraphs (A) - (C) of this
paragraph are met.
(A) all contents from process equipment or tanks must
be removed to the maximum extent practicable prior to opening facilities
to commence degassing and maintenance.
(B) facilities must be degassed using best management
practices to ensure air contaminants are removed from the system to
the extent allowed by facility design.
(C) tanks may be emptied or degassed by forced ventilation
(i) only one vacuum truck is in use at any time;
(ii) emissions are directed out the top of the tank;
(iii) emissions are routed through a closed system
to a control device.
(10) abrasive blasting, surface preparation, and surface
coating of facilities and structures used at the site in oil and gas
handling and production.
(c) Best Management Practices.
(1) All facilities with the potential to emit air contaminants
must be maintained in good condition and operated properly.
(2) Each permit holder shall establish, implement,
and update, as appropriate, a program to maintain and repair facilities
as required by paragraph (1) of this subsection. The minimum requirements
of this program must include:
(A) a maintenance program developed by the permit holder
for all facilities that is consistent with good air pollution control
practices, or alternatively, manufacturer's specifications and recommended
programs applicable to facility performance and the effect on emissions;
(B) cleaning and routine inspection of all facilities;
(C) repair of facilities on timeframes that minimize
failures and maintain performance;
(D) training of personnel who implement the maintenance
(E) records of conducted planned MSS activities.
