Standards for natural gas-driven pneumatic controllers:
(a) new pneumatic controllers shall have an
emission rate of zero. A natural gas driven pneumatic controller replacing an
existing natural gas driven pneumatic controller at an existing facility is an
existing pneumatic controller for purposes of Section 20.2.50.122
NMAC.
(b) owners and operators of
existing pneumatic controllers shall meet the required percentage of
non-emitting controllers within the deadlines in tables 1 and 2 of Paragraph
(3) of Subsection B of 20.2.50.122 NMAC, and shall comply with the following:
(i) by July 1, 2023, the owner or operator
shall determine the total controller count for all controllers subject to each
table separately at all of the owner or operator's affected facilities that
commenced construction before the effective date of this Part. The total
controller count for each table must include all emitting pneumatic controllers
and all non-emitting pneumatic controllers, except that pneumatic controllers
necessary for a safety or process purpose that cannot otherwise be met without
emitting natural gas shall not be included in the total controller count. This
final number is the total historic controller count. Controllers identified as
required for a safety or process purpose after July 1, 2023, shall not affect
the total historic controller count.
(ii) determine which controllers in the total
controller count for each table are non-emitting and sum the total number of
non-emitting controllers and designate those as total historic non-emitting
controllers.
(iii) determine the
total historic non-emitting percent of controllers for each table by dividing
the total historic non-emitting controller count by the total historic
controller count and multiplying by 100.
(iv) based on the percent calculated in (iii)
above for each table, the owner or operator shall determine which provisions of
tables 1 and 2 of Paragraph (3) of Subsection B of 20.2.50.122 NMAC apply and
the replacement schedule the owner or operator must meet.
(v) if an owner or operator meets at least
seventy-five percent total non-emitting controllers using the calculation
methodology in Subparagraph (b) of Paragraph (4) of Subsection B of 20.2.50.122
NMAC by January 1, 2025, for either or both table 1 or table 2, the owner or
operator is not thereafter subject to the requirements of tables 1 and/or 2 of
Paragraph (3) of Subsection B of 20.2.50.122 NMAC.
(vi) if after January 1, 2027, an owner or
operator's remaining pneumatic controllers are not cost-effective to retrofit,
the owner or operator may submit a cost analysis of retrofitting those
remaining units to the department. The department shall review the cost
analysis and determine whether those units qualify for a waiver from meeting
additional retrofit requirements.
(c) owners and operators of existing natural
gas driven pneumatic controllers shall demonstrate compliance with tables 1 and
2 of Paragraph (3) of Subsection B of 20.2.50.122 NMAC, on January 1, 2024,
January 1, 2027, and January 1, 2030, as follows:
(i) determine which controllers are emitting
(excluding pneumatic controllers necessary for safety or process reasons
pursuant to Subparagraph (d) of Paragraph (4) of Subsection B of 20.2.50.122
NMAC) and sum the total number of emitting controllers for table 1 and table 2
facilities separately.
(ii)
determine the percentage of non-emitting controllers by using the following
equation for table 1 and table 2 facilities separately:
Total Percentage of Non-Emitting Controllers =
100 - ((total emitting controllers / total historic controller count) x 100)
(iii) compliance is demonstrated if the Total
Percentage of Non-Emitting Controllers calculated pursuant to Subparagraph (c)
of Paragraph (4) of Subsection B of 20.2.50.122 NMAC is less than or equal to
the value for that year in the Total Historic Percentage of Non-Emitting
Controllers row (as calculated pursuant to Subparagraph (b)(i)-(iv) of
Paragraph (4) of Subsection B of 20.2.50.122 NMAC) in table 1 or table 2, as
applicable, of Paragraph (3) of Subsection B of 20.2.50.122 NMAC.
(d) No later than January 1, 2024,
a pneumatic controller with a bleed rate greater than six standard cubic feet
per hour is permitted when the owner or operator has demonstrated that a higher
bleed rate is required based on functional needs, including response time,
safety, and positive actuation. An owner or operator that seeks to maintain
operation of an emitting pneumatic controller as excepted for process or safety
reasons under Subparagraph (a)(i) of Paragraph (4) of Subsection B of
20.2.50.122 NMAC must prepare and document the justification for the safety or
process purpose prior to the installation of a new emitting controller or the
retrofit of an existing controller. The justification shall be certified by a
qualified professional or inhouse engineer.
(e) Temporary pneumatic controllers that emit
natural gas and are used for well abandonment activities or used prior to or
through the end of flowback, and pneumatic controllers used as emergency
shutdown devices located at a well site, are not subject to the requirements of
Subsection B of 20.2.50.122 NMAC.
(f) Temporary or portable pneumatic
controllers that emit natural gas and are on-site for less than 90 days are not
subject to the requirements of Subsection B of 20.2.50.122 NMAC.
(5) Standards for natural
gas-driven pneumatic diaphragm pumps:
(a) new
pneumatic diaphragm pumps located at natural gas processing plants shall have
an emission rate of zero.
(b) new
pneumatic diaphragm pumps located at well sites, tank batteries, gathering and
boosting stations, or transmission compressor stations with access to
commercial line electrical power shall have an emission rate of zero.
(c) existing pneumatic diaphragm pumps
located at well sites, tank batteries, gathering and boosting stations, natural
gas processing plants, or transmission compressor stations with access to
commercial line electrical power shall have an emission rate of zero within two
years of the effective date of this Part.
(d) owners and operators of pneumatic
diaphragm pumps located at well sites, tank batteries, gathering and boosting
stations, or transmission compressor stations without access to commercial line
electrical power shall reduce VOC emissions from the pneumatic diaphragm pumps
by ninety-five percent if it is technically feasible to route emissions to a
control device, fuel cell, or process. If there is a control device available
onsite but it is unable to achieve a ninety-five percent emission reduction,
and it is not technically feasible to route the pneumatic diaphragm pump
emissions to a fuel cell or process, the owner or operator shall route the
pneumatic diaphragm pump emissions to the control device within two years of
the effective date of this Part.
C. Monitoring requirements:
(1) Pneumatic controllers or diaphragm pumps
not using natural gas or other hydrocarbon gas as a motive force are not
subject to the monitoring requirements in Subsection C of 20.2.50.122
