				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.
