ALL ROADS

LEAD TO HI-VAC

®

release of March 10, 2005 that
designated 811 as the nationwide
number for contractors and others
to call before conducting excavation activities:
"811 is one of only eight 'N11'
codes, five of which have been assigned for nationwide use. Those
assigned are: 211 for government
information and referral services;
311 for non-emergency police
and government services; 511 for
travel and information services;
711 for telephone relay services
for the hearing impaired; and 911
for emergencies. Prior to today's
decision, the Commission had not
assigned 411, 611 and 811 for nationwide use, but these numbers
have been widely used by carriers
for various purposes.
"This nationwide abbreviated dialing code will provide an effective
replacement for an array of numbers used across the nation to connect to communication systems
operated by underground utility
operators, and state and local governments. One Call notification
systems enable contractors to give
advance notice of their plans to
excavate so that utility companies
can mark underground facilities
prior to excavation to prevent
damage to these facilities."
The Federal Communications
Commission ordered that 811 be
operational two years from publication of its designation in the
Federal Register, and it went live in
March of 2007.

Application of 811
How does the use - or non-use -
of 811 affect large interstate
operations?
Laura Arellano-Briot, a regulatory compliance specialist with
Denbury Resources Inc., consulted
her company's pipeline foremen,
their pipeline superintendent and
the supervisor of pipeline services about their experience with
the 811 system. Their responses
should help serve as a guideline on
why using this free service is so important to the continued health of
our national pipeline system.

How does the 811 system work
to protect your infrastructure?
For our DOT-PHMSA regulated
pipeline infrastructure, the 811
system provides essential information to our pipeline operations
personnel, other operators and the
contractors/excavators involved in
excavation taking place near our
pipeline facilities. The 811 system
initiates required collaboration between the stakeholders involved,
thus enhancing safety during
excavation activities. The 811 system also serves as a single point of
contact where information can be
found about underground facilities
located in specific areas within the
state.
Do you do your own locates or
contract out?
On our pipeline facilities, we
perform our own line locates.
Personnel who perform this task
are operator qualified per requirements listed in 49 CFR §192 and
§195. In addition, some personnel
hold line locating certification,
and Denbury is examining the
option to send more personnel
through nationwide certified line
locating courses.
How many locates occur
per year?
For our pipeline facilities, on average 12,500 locate tickets for
approximately 1,100 miles of pipelines are received per year, which
are either cleared or marked. In
addition, Denbury physically monitors any excavation activity taking
place within 25 feet of underground facilities until completion.
What do you estimate the 811
system has saved in cost of
repair?
A lot of variables would determine
the actual cost of an excavation
damage repair to our pipeline facilities, such as pipeline vintage,
materials, downtime, impact to
business, stakeholders affected,
and extent of damage to people,
property and the environment.
To date, Denbury has not had to
make any repairs due to pipeline
