RIN 2137-AC38
Increased Inspection Requirements
AGENCY: Research and Special Programs Administration (RSPA), DOT.
ACTION: Public workshop notice.
-----------------------------------------------------------------------
SUMMARY: This notice announces a public workshop to discuss issues
relevant to development of regulations requiring increased inspection
of certain gas and hazardous liquid pipelines. The increased inspection
would apply to all gas transmission and hazardous liquid pipelines
under RSPA safety regulations in high-density population areas. In
addition, hazardous liquid pipelines would have to be inspected in
unusually sensitive environmental areas and at crossings of navigable
waterways. Congress mandated the increased inspection regulations to
reduce the risk of pipeline accidents due to structural defects.
DATES: The workshop will be on October 18, 1995, from 8:30 am to 4:00
pm. Persons who want to participate in the workshop should call (703)
218-1449 or e-mail their name, affiliation and phone number to
[email protected] before close of business October 2, 1995. The workshop
is open to all interested persons, but RSPA may limit participation
because of space considerations and the need to obtain a spectrum of
views. Callers will be notified if participation is not open.
Persons who are unable to attend may submit written comments in
duplicate by November 27, 1995. Interested persons should submit as
part of their written comments all material that is relevant to a
statement of fact or argument. Late filed comments will be considered
so far as practicable.
ADDRESSES: The workshop will be held at the U.S. Department of
Transportation, Nassif Building, 400 Seventh Street, SW, Room 9230-34,
Washington, DC. Non-federal employee visitors are admitted into the DOT
headquarters building through the southwest entrance at Seventh and E
Streets, SW.
Send written comments in duplicate to the Dockets Unit, Room 8421,
Research and Special Programs Administration, U.S. Department of
Transportation, 400 Seventh Street, SW, Washington, DC 20590-0001.
Identify the docket and notice numbers stated in the heading of this
notice.
All comments and docketed material will be available for inspection
and copying in Room 8421 between 8:30 am and 4:30 pm each business day.
A summary of the workshop will be available from the Dockets Unit about
three weeks after the workshop.

document or other material in the docket.
SUPPLEMENTARY INFORMATION:
I. Background
Pipelines can have various types of defects that threaten their
structural integrity. These defects can originate during the
manufacture of pipe (e.g., seam weld defects) or during construction of
the pipeline (e.g., scratches, gouges, dents, and girth weld flaws).
Later, during operation of the pipeline, more defects can occur that
threaten pipeline integrity. These defects commonly include metal loss
due to corrosion, environmental or fatigue cracking, and scratches,
gouges, or dents caused by outside forces, usually excavation
equipment.
Defects that are not detected and removed can deteriorate or grow,
causing pipeline accidents. For example, RSPA data show that in 1992,
17 percent of the accidents on gas transmission and gathering systems
were due to corrosion, 40 percent were due to outside force damage, and
9 percent were due to material or construction defects. Similarly, on
hazardous liquid pipelines, corrosion caused 20 percent of the
accidents; outside forces, 22 percent; and material or construction
defects, 17 percent.
These data do not distinguish outside force accidents that occurred
immediately on impact from accidents that occurred after impact because
of a defect created by the impact. However, several major pipeline
accidents have been attributed to undetected structural defects caused
by an outside force. For example, on March 28, 1993, a 36-inch
hazardous liquid pipeline failed near Reston, Virginia, spilling over
400,000 gallons of diesel fuel into Sugarland Run Creek, an
ecologically-sensitive tributary of the Potomac River. An investigation
showed that outside force damage had probably occurred.
The 102d Congress was concerned about the risk of pipeline failures
caused by undetected structural defects. So, it directed DOT to issue
regulations that require the periodic inspection of certain pipeline
facilities (49 U.S.C. Sec. 60102(f)(2)). Under this congressional
mandate, gas and hazardous liquid pipelines (except gas distribution
lines) must be inspected in high-density population areas. In addition,
hazardous liquid pipelines must be inspected in areas that are
unusually sensitive to environmental damage in the event of a pipeline
accident, and at crossings of navigable waterways. The regulations are
to prescribe any circumstances in which inspections must be conducted
with an instrumented internal inspection device. Where the device is
not required, the regulations are to require the use of an inspection
method that is at least as effective as using the device in providing
for the safety of the pipeline.
II. Workshop
Consistent with the President's regulatory policy (E.O. 12866),
RSPA wants to accomplish this congressional mandate at the least cost
to society. Toward this end, RSPA is seeking early public participation
in the rulemaking process by holding a public workshop at which
participants, including RSPA staff, may exchange views on relevant
issues. RSPA hopes the workshop will enable government and industry to
reach a better understanding of the problem and the potential solutions
before proposed rules are issued.
Workshop participants are encouraged to focus their remarks on
[[Page 44822]]
the following issues, but may address other issues as time permits and
in supplementary written comments:
A. Apart from internal inspection, are current DOT safety
regulations that require periodic inspection of pipelines for corrosion
and leaks sufficient under the mandate?
B. What are the circumstances in which the regulations should
require operators to use instrumented internal inspection devices?
C. What defects should the regulations require the use of
instrumented internal inspection devices to detect?
D. What other inspection methods are as effective as using an
instrumented internal inspection device?
E. How should the regulations define areas of high-density
population, areas unusually sensitive to environmental damage in the
event of a pipeline accident, and navigable waterways.
F. What are the per mile costs of inspection with instrumented
internal inspection devices and the factors that determine those costs?
