Rule 642.
(1) As
used in this rule, "pneumatic pump" means a positive displacement reciprocating
unit driven by natural gas used for injecting precise amounts of chemicals into
a process stream or for freeze protection glycol circulation.
(2) A person shall not cause or allow the
emission of any volatile organic compound associated with oil and natural gas
production and natural gas processing segments of the oil and natural gas
industry in excess of the limitations of this rule from the use of existing
single natural gas driven pneumatic pumps when the pumps are both of the
following:
(a) Located inside the 2015 ozone
nonattainment area.
(b) Utilized at
a natural gas processing plant or well site.
(3) Except as required in subrule (6), the
provisions of this rule do not apply to a pneumatic pump that is either of the
following:
(a) If it is determined through an
engineering assessment that routing a pneumatic pump to a control device or a
process is technically infeasible due to insufficient gas pressure or control
device capacity, including the event in which there is no control device or in
which the control device or process is removed from the site, the following
provisions must be met:
(i) An assessment of
technical infeasibility must be conducted and must include, but is not limited
to, safety considerations, distance from the control device, pressure losses
and differentials in the closed vent system, and the ability of the control
device to handle the pneumatic pump emissions which are routed to them. This
assessment must be prepared under supervision of a qualified professional
engineer as approved in 40
CFR 60.5393a.
(ii) The professional engineer shall sign and
certify this prepared assessment.
(b) In operation less than 90 days per
calendar year. For purposes of this rule, any period of operation during a
calendar day counts toward the 90-day annual threshold.
(4) A person shall not cause or allow the
emission of any volatile organic compound from pneumatic pumps, unless the
following provisions are met:
(a) At natural
gas processing plants, zero emissions or 100% control from each diaphragm pump
by use of a control device or instrument air system in place of the natural
gas-driven pump.
(b) At a well
site, emissions from each existing diaphragm pump with control devices, must be
reduced by 95% by weight or greater as determined by subrule (5) of this rule,
or, if 95% control is not achievable, by the maximum control efficiency
possible as described in subrule (6) of this rule.
(c) At a well site that installs a control
device after March 1, 2023, the emissions from the pneumatic pump must be
captured and routed to the control device.
(d) If reducing emissions by use of a control
device or by routing to a process, the pneumatic pump must connect emissions
through a closed vent system meeting the requirements of
R
336.1640(4)(b)(ii).
(5) Compliance with this rule must be
determined as follows:
(a) All pneumatic
pumps must be tagged with an identifying marker to allow tracking for reporting
as described in subrule (6) of this rule.
(b) Initial performance and compliance
testing must be conducted in accordance with a stack testing protocol, or
alternative testing protocol, approved by the department.
(c) All control devices must have an
approvable operation and maintenance plan that contains, at a minimum, the
following:
(i) A schedule of maintenance for
the control devices in use.
(ii) An
inspection schedule at least once every calendar month.
(iii) Written instructions from the
manufacturer.
(6) A person operating a pneumatic pump
subject to this rule shall obtain current information and maintain records for
all requirements in sufficient detail to determine compliance. The records must
be made available to the department upon request and must include the
following, as appropriate:
(a) Notes of all
pumps with control, and the respective control efficiencies, as determined by
the performance test used in subrule (5) of this rule, that may include a stack
test, calibrated bag test, or engineering calculations.
(b) For all pumps with a control efficiency
less than the control efficiency required by subrule (4) of this rule,
infeasibility of meeting applicable criteria for capture and control for any
uncontrolled pump which may include factors such as safety, distance, pressure
losses and differentials, and the capacity of any available existing control
device, to show that subrule (4) of this rule is not attainable.
(c) For all pumps at well sites without
controls, a statement of confirmation that no control device has been
installed.
(d) Before March 1,
2023, an initial report must be submitted to the department describing initial
compliance.
(e) A report must be
submitted to the department if a control device is installed on site after
March 1, 2023.
