[Docket No. P-95-2W; Notice 1]
Transportation of Natural Gas by Pipeline Grant of Waiver;
Columbia Gas Transmission Corporation
Columbia Gas Transmission Corporation has petitioned the Research
and Special Programs Administration (RSPA) for temporary waiver of a
pipeline safety standard that requires plastic pipe to be installed
below ground level (49 CFR 192.321(a)). The petition applies to
approximately 1000 feet of 2-inch plastic pipe, which is to replace
Line 778 and Line 2060 in a rural area near the town of Kirby in Greene
County, Pennsylvania.
[[Page 55753]]
According to the petition, coal mining threatens to cause ground
subsidence beneath the two existing pipelines. To avoid possible line
breakage and service outage, Columbia proposes to replace these
pipelines with approximately 1000 feet of plastic pipeline installed
temporarily above ground. After necessary state and local permits are
obtained to authorize ditching for burial, Columbia plans to bury the
plastic pipeline 3 feet below ground within 6 to 8 months after
construction.
The petition explains that the above ground plastic pipeline would
present little risk to the public because the area is rural, with no
dwellings within half a mile of the pipeline. Also, line markers are to
be spaced at 100-foot intervals, and gas warning tape and other
suitable warnings would be installed along the pipeline route. In
addition, Columbia stated it will patrol the pipeline monthly, or more
frequently if necessary, to assure the integrity of the pipeline while
it is above ground. Columbia further stated that it did not expect
external loading or vandalism to be a problem on the pipeline, nor does
it expect ultraviolet degradation during the period of exposure.
In a separate proceeding, ``Regulatory Review; Gas Pipeline Safety
Standards,'' RSPA has proposed to revise Sec. 192.321(a) to allow the
installation of plastic pipe above ground under certain conditions
(Docket PS-124; 57 FR 39576; Aug. 31, 1992). The proposed conditions
would limit aboveground use to 30 days in places where external damage
is unlikely or adequate protection is provided. In addition, the
plastic pipe would have to be resistant to ultraviolet light and
temperature extremes, and not have been previously used above ground.
RSPA received written comments on the proposal from 14 gas pipeline
companies, 3 pipeline-related associations, and a state pipeline safety
agency. No one objected to the concept of temporary aboveground use. In
fact, many commenters suggested that the proposal did not go far
enough, asserting that permanent aboveground installations should be
allowed when plastic pipe is encased in steel conduit. Others argued
that a 30-day limit on temporary usage would be too brief in view of
the time it may take to construct a permanent underground installation.
Still other commenters argued the proposed time limit and prohibition
against reinstalling aboveground plastic pipe above ground were
unnecessary. They contended that commercially available plastic pipe
can be exposed to ultraviolet light for at least 2 years without
degradation of material properties. These commenters suggested RSPA
allow the use of plastic pipe above ground according to pipe
manufacturers' recommended exposure limits.
Because RSPA has already proposed to allow the limited use of
plastic pipe above ground, we believe that waiving Sec. 192.321(a) as
Columbia has proposed is appropriate. However, in view of the issue in
Docket PS-124 concerning the safe period for temporary aboveground
installations, we are granting the waiver on condition that the plastic
pipe does not remain above ground longer than the manufacturer
recommends for aboveground exposure. Given that Docket PS-124 has
already afforded the public an opportunity to comment on above ground
use of plastic pipe, we believe further notice and opportunity to
comment on the matter within the context of this waiver proceeding
would be unnecessary. Therefore, this waiver is granted as final
without further public notice.
For the reasons explained above, RSPA, by this order, finds that
the requested waiver of Sec. 192.321(a) is not inconsistent with
pipeline safety. Therefore, effective immediately, Columbia's petition
for waiver is granted, provided the installation is carried out as
proposed in the petition and does not exceed the manufacturer's
recommended maximum period of exposure.
Authority: 49 U.S.C. 6018(c); and 49 CFR 1.53.
