Well and lease equipment and gas gathering pipelines
Cite as N.D. Admin. Code ยง 43-02-03-29
1.
Wellhead and lease equipment with a working pressure at least equivalent to the calculated or
known pressure to which the equipment may be subjected must be installed and maintained.
Equipment on producing wells must be installed to facilitate gas-oil ratio tests, and static
bottom hole or other pressure tests. Valves must be installed and maintained in good working
order to permit pressure readings to be obtained on both casing and tubing.
2.
All newly constructed underground gas gathering pipelines must be devoid of leaks and
constructed of materials resistant to external corrosion and to the effects of transported fluids.
All such pipelines installed in a trench must be installed in a manner that minimizes
interference with agriculture, road and utility construction, the introduction of secondary
stresses, the possibility of damage to the pipe, and tracer wire shall be buried with any
nonconductive pipes installed. When a trench for an underground gas gathering pipeline is
backfilled, it must be backfilled in a manner that provides firm support under the pipe and
prevents damage to the pipe and pipe coating from equipment or from the backfill material.
a.
The operator of any underground gas gathering pipeline placed into service on August 1,
2011, to June 30, 2013, shall file with the director, by January 1, 2015, a geographical
information system layer utilizing North American datum 83 geographic coordinate
system (GCS) and in an environmental systems research institute (Esri) shape file format
showing the location of the pipeline centerline. Any shape files that have been created for
any underground gas gathering pipeline placed into service prior to August 1, 2011, must
also be filed with the director. The operator of any underground gas gathering pipeline
placed into service after June 30, 2013, shall file with the director, within one hundred
eighty days of placing into service, a geographical information system layer utilizing
North American datum 83 geographic coordinate system (GCS) and in an environmental
systems research institute (Esri) shape file format showing the location of all compressor
sites, buried drip tanks, and the pipeline centerline. An affidavit of completion must
accompany each layer containing the following information:
(1)
A statement that the pipeline was constructed and installed in compliance with
section 43-02-03-29.
(2)
The outside diameter, minimum wall thickness, composition, internal yield pressure,
and maximum temperature rating of the pipeline, or any other specifications
deemed necessary by the director.
(3)
The anticipated operating pressure of the pipeline.
(4)
The type of fluid that will be transported in the pipeline and direction of flow.
(5)
Pressure to which the pipeline was tested prior to placing into service.
(6)
The minimum pipeline depth of burial.
(7)
In-service date.
(8)
Leak detection and monitoring methods that will be utilized after in-service date.
(9)
Pipeline name.
(10)
Accuracy of the geographical information system layer.
b.
If an underground gas gathering pipeline or any part of such pipeline is abandoned, the
operator shall leave such pipeline in a safe condition by conducting the following:
(1)
Disconnect and physically isolate the pipeline from any operating facility or other
pipeline.
(2)
Cut off the pipeline or the part of the pipeline to be abandoned below surface at
pipeline level.
(3)
Purge the pipeline with fresh water, air, or inert gas in a manner that effectively
removes all fluid.
(4)
Remove cathodic protection from the pipeline.
(5)
Permanently plug or cap all open ends by mechanical means or welded means.
3.
Within one hundred eighty days of completing the abandonment of an underground gas
gathering pipeline the operator of the pipeline shall file with the director a geographical
information system layer utilization North American datum 83 geographic coordinate system
(GCS) and in an environmental systems research institute (Esri) shape file format showing the
location of the pipeline centerline and an affidavit of completion containing the following
information:
a.
A statement that the pipeline was abandoned in compliance with section 43-02-03-29.
b.
The type of fluid used to purge the pipeline.
4.
Aboveground pipeline markers must be placed and maintained over each buried underground
gas gathering pipeline or portion thereof at the discretion of the director when necessary to
protect public health and safety. The markers must contain at least the following on a
background of sharply contrasting color: the word "Warning", "Caution", or "Danger" followed
by the fluid transported pipeline, the name of the operator, and current emergency phone
number.
The requirement to submit a geographical information system layer may not be construed to be
required on buried piping utilized to connect flares, tanks, treaters, or other equipment located entirely
within the boundary of a well site or production facility.
