The rules enacted almost five years ago to make the
nation's pipelines safer seem to be having a positive
effect. Operators have been identifying and addressing the
risks associated with pipelines that are located in
populated areas, as required by law.

U.S. lawmakers are now trying to beef up those pipeline
safety laws ratified in 2002. But, Congress adjourned
before the House and Senate could complete their work on
the matter. New bills under discussion, for example, would
have increased the number of inspectors from 90 today to
135, all by 2010 at a cost of $6 million a year.
It's possible that lawmakers will convene in a special
lame duck session after the mid-term elections. Regulators
are expressing concern with the relative few number of
inspectors, noting today's levels amount to one examiner
for every 18,000 miles of pipeline in this country --
something in which Congress is likely to agree.
Inspections show that operators are making good
progress when it comes to assessing their pipelines and
making any subsequent repairs. But, according to
government watchdogs, they need to better document their
management practices and decisions. Indeed, the U.S.
Department of Transportation's Inspector General's office
says that operators have fixed the major threats that have
been identified but some of the reports contain errors,
which makes analyzing the actual threats more difficult.
The Government Accountability Office (GAO) generally
concurs with those findings. It says that pipeline
inspectors have examined 6,700 miles in highly populated
areas. They have subsequently found 338 problems that
required immediate repair -- about one problem for every
20 miles. "While the gas integrity management program is
still being implemented, early indicators suggest that it
enhances public safety by supplementing existing safety
standards with risk-based management principles," says
Katherine Siggerud, director of physical structure issues
for the GAO.
On average, about 3 people have died and about 8 others
have been injured annually over the last 10 years in
natural gas transmission pipeline incidents, according to
the GAO. The number of incidents has increased from 77 in
1996 to 122 in 2004 and 200 in 2005. Altogether, there are
2.4 million miles of interstate oil and gas pipelines in
the United States as well as 1.8 million miles of
distribution lines.
The 2002 pipeline safety law includes provisions that
require gas transmission pipeline operators to
systematically assess the risks of pipelines located in
populated and sensitive areas such as parks. A pipeline is
at risk if there is corrosion, welding defects or third
party damage tied to excavation. The law requires that
operators perform these evaluations on half of the
pipeline mileage in highly populated areas by December
2007 and the remainder by December 2012. The lines with
the greatest potential for risks are to be examined first
and subsequently every 7 years.
Productive Changes
According to the Transportation Department's
statistics, the single largest cause -- 82 percent -- of
all distribution pipeline incidents reported to federal
pipeline safety authorities between 2001 and 2005 resulted
from excavation damage.
The fix is not easy. Right now, state pipeline safety
programs are responsible for overseeing 222,000 miles of
natural gas and liquid transmission and gathering lines.
They are also charged with watching over 1 million miles
of natural gas distribution lines and 764,000 miles of
service lines. The Transportation Department reimburses
the states half of their pipeline safety enforcement
costs.
The American Gas Association explains that data
collected over the last five years shows that states with
strong enforcement programs have better safety records
than those without such programs. It points to Virginia
and Minnesota, which have reported reduced problems
because they have implemented those laws.
For the states to be effective, they must have public
outreach programs as well as good working relations with
the local distribution companies that they oversee. Along
those lines, each natural gas utility employs safety
professionals, provides ongoing training and conducts its
own inspections and any possible repairs. While local
utilities are diligent when it comes to running safe
pipelines, they say they have little control over the
third parties that cause damage to their lines because of
excavation.
"Pipeline operators recognize the need to change this
risky behavior in order to protect their lines and have
used educational efforts to help raise awareness about the
need for safe practices, but with a limited effect," says
Frank Bender, vice president of gas distribution for
Baltimore Gas & Electric.
Overall, both federal and state regulators are making
strides. Beyond more thorough inspections and public
outreach programs, they have incorporated new technologies
to enable them to better collect and analyze data so as to
detect and respond to problems. Toward that end, federal
and state agencies collaborate when it comes to training,
sharing databases and facilitating communications.
At the same time, regulators are imposing and
collecting larger penalties. The Transportation Department
says that 2003 was the first year that they could levy
fines of some substance. In 2005, regulators proposed $4
million in penalties -- more than double the amount it
proposed in 2003. And from 2003 to 2005, they have
collected 94 percent of that amount.
The progress has not gone unnoticed. But, more remains
to be done, namely the addition of new inspectors who
could do a more detailed and more frequent job of
overseeing the nation's pipeline system. Congress,
luckily, agrees. But any change may have to wait until the
political season is over and a new year has begun. For far more extensive news on the energy/power
