| (a) This section does not apply to plastic pipelines.
(b) By February 1, 2002, operators of intrastate transmission
lines subject to the requirements of 49 CFR Part 192 or 49 CFR Part
195 shall have designated on a system-by-system or segment within
each system basis whether the pipeline operator has chosen to use
the risk-based analysis pursuant to paragraph (1) of this subsection
or the prescriptive plan authorized by paragraph (2) of this subsection.
Hazardous liquid pipeline operators using the risk-based plan shall
complete at least 50% of the initial assessments by January 1, 2006,
and the remainder by January 1, 2011; operators using the prescriptive
plan shall complete the initial integrity testing by January 1, 2006,
or January 1, 2011, pursuant to the requirements of paragraph (2)
of this subsection. Natural gas pipeline operators using the risk-based
plan shall complete at least 50% of the initial assessments by December
17, 2007, and the remainder by December 17, 2012; operators using
the prescriptive plan shall complete the initial integrity testing
by December 17, 2007, or December 17, 2012, pursuant to the requirements
of paragraph (2) of this subsection.
(1) The risk-based plan shall contain at a minimum:
(A) identification of the pipelines and pipeline segments
or sections in each system covered by the plan;
(B) a priority ranking for performing the integrity
assessment of pipeline segments of each system based on an analysis
of risks that takes into account:
(i) population density;
(ii) immediate response area designation, which, at
a minimum, means the identification of significant threats to the
environment (including but not limited to air, land, and water) or
to the public health or safety of the immediate response area;
(iii) pipeline configuration;
(iv) prior in-line inspection data or reports;
(v) prior pressure test data or reports;
(vi) leak and incident data or reports;
(vii) operating characteristics such as established
maximum allowable operating pressures (MAOP) for gas pipelines or
maximum operating pressures (MOP) for liquids pipelines, leak survey
results, cathodic protection surveys, and product carried;
(viii) construction records, including at a minimum
but not limited to the age of the pipe and the operating history;
(ix) pipeline specifications; and
(x) any other data that may assist in the assessment
of the integrity of pipeline segments.
(C) assessment of pipeline integrity using at least
one of the following methods appropriate for each segment:
(i) in-line inspection;
(ii) pressure test;
(iii) direct assessment; or
(iv) other technology or assessment methodology not
specifically listed in this paragraph after approval by the director.
(D) management methods for the pipeline segments which
may include remedial action or increased inspections as necessary;
and
(E) periodic review of the pipeline integrity assessment
and management plan every 36 months, or more frequently if necessary.
(2) Operators electing not to use the risk-based plan
in paragraph (1) of this subsection shall conduct a pressure test
or an in-line inspection and take remedial action in accordance with
the following schedule:

(c) Within 185 days after receipt of notice that an
operator's plan is complete, the Commission shall either notify the
operator of the acceptance of the plan or shall complete an evaluation
of the plan to determine compliance with this section.
(d) After the completion of the assessment required
under either plan, the operator shall promptly remove defects that
are immediate hazards and, no later than the next test interval, shall
mitigate any anomalies identified by the test that could reasonably
be predicted to become hazardous defects.
(e) If a pipeline that is not subject to this section
undergoes any change in circumstances that results in the pipeline
becoming subject to this section, then the operator of such pipeline
shall establish integrity of the pipeline pursuant to the requirements
of this section prior to any further operation. Such changes include
but are not limited to an addition to the pipeline, change in the
operating pressure of the pipeline, change from inactive to active
status, change in population in the area of the pipeline, or change
of operator of the pipeline segment. If a pipeline segment is acquired
by a new operator, the pipeline segment can continue to be operated
without establishing pipeline integrity as long as the new operator
utilizes the prior operator's operation and maintenance procedures
for this pipeline segment. If the population in the area of a pipeline
segment changes, the pipeline segment can continue to operate without
establishing pipeline integrity until such time as the operator determines
whether or not the change in population affects the criteria applicable
to the integrity management program, but for no longer than the time
frames established under 49 CFR Part 192 or 195.
