New Mexico Administrative Code › Title 20 - ENVIRONMENTAL PROTECTION › Chapter 2 - AIR QUALITY (STATEWIDE) › Part 50 - OIL AND GAS SECTOR - OZONE PRECURSOR POLLUTANTS › Section 20.2.50.115 - CONTROL DEVICES AND CLOSED VENT SYSTEMS

Current through Register Vol. 35, No. 13, July 16, 2024
A.
Applicability:
These
				requirements apply to control devices and closed vent systems as defined in
				20.2.50.7 NMAC and used to comply with the emission standards and emission
				reduction requirements in this Part.
B.
General requirements:
(1) Control devices used to demonstrate
				compliance with this Part shall be installed, operated, and maintained
				consistent with manufacturer specifications, and good engineering and
				maintenance practices.
(2) Control
				devices shall be adequately designed and sized to achieve the control
				efficiency rates required by this Part and to handle the reasonably expected
				range of inlet VOC or NOx concentrations or volumes.
(3) The owner or operator shall inspect
				control devices visually or consistent with applicable federally approved
				inspection methods at least monthly to identify defects, leaks, and releases,
				and to ensure proper operation. Prior to an inspection or monitoring event, the
				owner or operator shall date and time stamp the event, and the required
				monitoring data entry shall be made in accordance with this Part.
(4) The owner or operator shall ensure that a
				control device used to comply with emission standards in this Part operates as
				a closed vent system that captures and routes VOC emissions to the control
				device, in order to minimize venting of unburnt gas to the
				atmosphere.
(5) The owner or
				operator of a permanent closed vent system for a centrifugal compressor wet
				seal fluid degassing system, reciprocating compressor, natural gas driven
				pneumatic pump, or storage vessel using a control device or routing emissions
				to a process shall:
(a) ensure the control
				device or process is of sufficient design and capacity to accommodate the
				expected range of emissions from the affected sources;
(b) conduct an assessment to confirm that the
				closed vent system is of sufficient design and capacity to ensure that
				emissions from the affected equipment are routed to the control device or
				process; and
(c) have the
				assessment certified by a qualified professional engineer or an in-house
				engineer with expertise regarding the design and operation of closed vent
				system(s) in accordance with Items (i) and (ii) of Subparagraph (c) of this
				section.
(i) The assessment of the closed
				vent system shall be prepared under the direction or supervision of a qualified
				professional engineer or an in-house engineer who signs the certification in
				Item (ii) of Subparagraph (c) of this section.
(ii) The owner or operator shall provide the
				following certification, signed and dated by a qualified professional engineer
				or an in-house engineer: "I certify that the closed vent system assessment was
				prepared under my direction or supervision. I further certify that the closed
				vent system assessment was conducted, and this report was prepared, pursuant to
				the requirements of this Part. Based on my professional knowledge and
				experience, and inquiry of personnel involved in the assessment, the
				certification submitted herein is true, accurate, and complete."
(d) An owner or operator of an
				existing closed vent system shall comply with the requirements of Paragraph (5)
				of Subsection B of 20.2.50.115 NMAC within three years of the effective date of
				this Part and within 90 days of startup for a new closed vent system.
(6) The owner or
				operator shall keep manufacturer specifications for all control devices on
				file. The information shall include the unique identification number, type of
				unit, manufacturer name, make, model, capacity, and destruction or reduction
				efficiency data.
