F. An operator of an intrastate pipeline
transporting LNG, hazardous liquid, or gas shall not construct any part of a
hazardous liquid, LNG, or gas pipeline system under a building. If a building
encroaches over a pipeline system, the operator may require the property owner
to remove the building from over the pipeline or to reimburse the operator the
cost associated with relocating the pipeline system. The operator shall
determine, within 90 days after discovering the encroachment, whether the
encroachment can be resolved within 180 days. If the operator determines that
the encroachment cannot be resolved within 180 days, the operator shall, within
90 days of discovery, submit to the AZOPS a written plan to resolve the
encroachment within a period longer than 180 days. The AZOPS may then extend
the 180-day requirement to allow the property owner and the operator to
implement the written plan to resolve the encroachment. If the operator does
not submit a written plan, and the encroachment is not resolved within 180 days
of discovery, the operator shall discontinue service to the pipeline system.
This modifies
49 CFR
192.361 and
195.210.
G. An operator of an intrastate distribution
pipeline transporting gas shall not construct any part of a pipeline system
less than 8 inches away from any other underground structure. If the 8-inch
clearance cannot be maintained, a sleeve, casing, or shielding shall be used.
This modifies
49 CFR
192.361.
H. An operator of an intrastate pipeline
transporting gas that has regulators, meters, or regulation meter sets that
have been out of service for 36 months shall disconnect the pipeline from all
sources and supplies of gas or hazardous liquids, purge the gas or hazardous
liquids from the pipeline being disconnected, and cap all ends within six
months after the 36 months have passed. This modifies
49 CFR
192.727.
I. An operator of an intrastate pipeline
shall not install or operate a gas regulator that might release gas within 3
feet of a source of ignition, an opening into a building, an air intake into a
building, or any electrical source that is not intrinsically safe. The 3 -foot
clearance from a source of ignition shall be measured from the vent or source
of release (discharge port), not from the physical location of the meter set
assembly. This subsection does not apply to building permits issued and
subdivisions platted before October 1, 2000. If an encroachment into the
required 3 -foot clearance is caused by an action of the property owner, an
occupant, or a provider after the effective date of this rule, the operator may
require the property owner to resolve the encroachment or to reimburse the
operator the cost associated with relocating the pipeline system. The operator
shall determine, within 90 days after discovering the encroachment, whether the
encroachment can be resolved within 180 days. If the operator determines that
the encroachment cannot be resolved within 180 days, the operator shall, within
90 days of discovery, submit to the AZOPS a written plan to resolve the
encroachment within a period longer than 180 days. The AZOPS may then extend
the 180-day requirement to allow the property owner and the operator to
implement the written plan to resolve the encroachment. If the operator does
not submit a written plan, and the encroachment is not resolved within 180 days
of discovery, the operator shall discontinue service to the affected pipeline
system. This modifies
49 CFR
192.357 and
192.361.
