Current through Register Vol. 35, No. 18, September 24, 2024
A.
Applicability: Individual
pipeline pig launcher and receiver operations with a PTE equal to or greater
than one tpy VOC located within the property boundary of, and under common
ownership or control with, well sites, tank batteries, gathering and boosting
stations, natural gas processing plants, and transmission compressor stations
are subject to the requirements of 20.2.50.121 NMAC.
B.
Emission standards:
(1) Owners and operators of affected pipeline
pig launcher and receiver operations shall capture and reduce VOC emissions
from pigging operations by at least ninety-five percent within two years of the
effective date of this Part. If a combustion control device is used, the
combustion device shall have a minimum design combustion efficiency of
ninety-eight percent.
(2) The owner
or operator conducting an affected pig launching and receiving operation shall:
(a) employ best management practices to
minimize the liquid present in the pig receiver chamber and to minimize
emissions from the pig receiver chamber to the atmosphere after receiving the
pig in the receiving chamber and before opening the receiving chamber to the
atmosphere;
(b) employ a method to
minimize emissions, such as installing a liquid ramp or drain, routing a
high-pressure chamber to a low-pressure line or vessel, using a ball valve type
chamber, or using multiple pig chambers;
(c) recover and dispose of receiver liquid in
a manner that minimizes emissions to the atmosphere to the extent practicable;
and
(d) ensure that the material
collected is returned to the process or disposed of in a manner compliant with
state law.
(3) The
emission standards in Paragraphs (1) and (2) of Subsection B of 20.2.50.121
NMAC cease to apply to an individual pipeline pig launching and receiving
operation if the actual annual VOC emissions of the launcher or receiver
operation are less than one tpy of VOC.
(4) An owner or operator complying with
Paragraphs (1) or (2) of Subsection B of 20.2.50.121 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 or operator of an affected pig launching and receiving site shall inspect
the equipment for leaks using AVO, RM 21, or OGI on either:
(a) a monthly basis if pigging operations at
a site occur on a monthly basis or more frequently; or
(b) prior tothe commencement and after the
conclusion of the pig launching or receiving operation, if less
frequent.
(2) The
monitoring shall be performed using the methodologies outlined in Subsection C
of 20.2.50.116 NMAC as applicable and at the frequency required in Paragraph
(1) of Subsection C of 20.2.50.121 NMAC. The monitoring shall be performed when
the pig trap is under pressure.
(3)
An owner or operator complying with Paragraphs (1) or (2) of Subsection B of
20.2.50.121 NMAC through use of a control device shall comply with the
monitoring requirements in 20.2.50.115 NMAC.
(4) The owner or operator shall comply with
the monitoring requirements in 20.2.50.112 NMAC.
D.
Recordkeeping requirements:
In addition to complying with the recordkeeping requirements in 20.2.50.112
NMAC, the owner or operator of an affected pig launching and receiving site
shall maintain a record of the following:
(1)
the pigging operation, including the location, date, and time of the pigging
operation;
(2) the data and
methodology used to estimate the actual emissions to the atmosphere and used to
estimate the PTE;
(3) date and time
of any monitoring and the results of the monitoring; and
(4) the type of control device and its make
and model.
E.
Reporting requirements: The owner or operator shall comply with
the reporting requirements in 20.2.50.112 NMAC.
