Current through Register Vol. 35, No. 18, September 24, 2024
A.
Applicability: Hydrocarbon liquid transfers located at existing
well sites, standalone tank batteries, gathering and boosting stations with one
or more controlled storage vessels, natural gas processing plants, or
transmission compressor stations are subject to the requirements of 20.2.50.120
NMAC within two years of the effective date of this Part. Hydrocarbon liquid
transfers at existing gathering and boosting stations (including associated
tank batteries) without any controlled storage vessels are subject to the
requirements of 20.2.50.120 NMAC on the schedule specified in Paragraph 1 of
Subsection B of 20.2.50.123 NMAC. Hydrocarbon liquid transfers located at new
well sites, standalone tank batteries, gathering and boosting stations, natural
gas processing plants, or transmission compressor stations are subject to the
requirements of 20.2.50.120 NMAC upon startup. The following facilities and
operations are not subject to the requirements of this Section:
(1) Any facility connected to an oil sales
pipeline that is routinely used for hydrocarbon liquid transfers;
(2) Well sites, standalone tank batteries,
gathering and boosting stations, natural gas processing plants, or transmission
compressor stations not connected to an oil sales pipeline that load out
hydrocarbon liquids to trucks fewer than thirteen (13) times in a calendar
year; and
(3) Transfers of
hydrocarbon liquid from a transfer vessel to a storage vessel subject to the
emission standards in 20.2.50.123 NMAC.
B.
Emission standards:
(1) The owner or operator of a hydrocarbon
liquid transfer operation shall use vapor balance, vapor recovery, or a control
device to control VOC emissions by at least ninety-five percent, when
transferring hydrocarbon liquid from a storage vessel to a tanker truck or
tanker railcar for transport. If a combustion control device is used, the
combustion device shall have a minimum design combustion efficiency of
ninety-eight percent.
(2) An owner,
operator, or personnel conducting the hydrocarbon liquid transfer using vapor
balance shall:
(a) transfer the vapor
displaced from the transfer truck or railcar being loaded back to the storage
vessel being emptied via a pipe or hose connected before the start of the
transfer operation. If multiple storage vessels are manifolded together in a
tank battery, the vapor may be routed back to any storage vessel in the tank
battery;
(b) ensure that the
transfer does not begin until the vapor collection and return system is
properly connected;
(c) inspect
connector pipes, hoses, couplers, valves, and pressure relief devices for
leaks;
(d) check the hydrocarbon
liquid and vapor line connections for proper connections before commencing the
transfer operation; and
(e) operate
transfer equipment at a pressure that is less than the pressure relief valve
setting of the receiving transport vehicle or storage vessel.
(3) Connector pipes and couplers
shall be inspected and maintained to ensure there are no liquid
leaks.
(4) Connections of hoses and
pipes used during hydrocarbon liquid transfers shall be supported on drip trays
that collect any leaks, and the materials collected shall be returned to the
process or disposed of in a manner compliant with state law.
(5) Liquid leaks that occur shall be cleaned
and disposed of in a manner that minimizes emissions to the atmosphere, and the
material collected shall be returned to the process or disposed of in a manner
compliant with state law.
(6) An
owner or operator complying with Paragraph (1) of Subsection B of 20.2.50.120
NMAC through use of a control device shall comply with the control device
requirements in 20.2.50.115 NMAC.
C.
Monitoring requirements:
(1) The owner, operator, or their designated
representative shall visually inspect the hydrocarbon liquid transfer equipment
monthly at staffed locations and semi-annually at unstaffed locations to ensure
that hydrocarbon liquid transfer lines, hoses, couplings, valves, and pipes are
not dripping or leaking. At least once per calendar year, the inspection shall
occur during a transfer operation. Leaking components shall be repaired to
prevent dripping or leaking before the next transfer operation, or measures
must be implemented to mitigate leaks until the necessary repairs are
completed.
(2) The owner or
operator of a hydrocarbon liquid transfer operation controlled by a control
device must follow manufacturer specifications for the device.
(3) Owners and operators complying with
Paragraph (1) of Subsection B of 20.2.50.120 NMAC through use of a control
device shall comply with the monitoring requirements in 20.2.50.115
NMAC.
(4) Prior to any monitoring
event, the owner or operator shall date and time stamp the event, and the
monitoring data entry shall be made in accordance with the requirements of this
Part.
(5) The owner or operator
shall comply with the monitoring requirements in 20.2.50.112 NMAC.
D.
Recordkeeping
requirements:
(1) The owner or
operator shall maintain a record of the following:
(a) the location of the facility;
(b) if using a control device, the type,
make, and model of the control device;
(c) the date and time stamp, including GPS of
the location, of any inspection;
(d) the name of the person(s) conducting the
inspection;
(e) a description of
any problem observed during the inspection; and
(f) the results of the inspection and a
description of any repair or corrective action taken.
(2) The owner or operator shall maintain a
record for each site of the annual total hydrocarbon liquid transferred and
annual total VOC emissions. Each calendar year, the owner or operator shall
create a company-wide record summarizing the annual total hydrocarbon liquid
transferred and the annual total calculated VOC emissions.
(3) The owner or operator shall comply with
the recordkeeping requirements in 20.2.50.112 NMAC.
E.
Reporting requirements: The
owner or operator shall comply with the reporting requirements in 20.2.50.112
NMAC.
