SUPPLEMENTARY INFORMATION:
A. Background and Purpose
A Presidential Directive to the Secretary of Transportation
(October 16, 1996) stated that in implementing the Pipeline Risk
Management Demonstration Program: ``The Secretary shall require each
project to achieve superior levels of public safety and environmental
protection when compared with regulatory requirements that otherwise
would apply.'' Thus, the process to select operators for this
Demonstration Program involves a comprehensive review to ensure that
the proposed project will provide the superior safety and environmental
protection required by this Directive. This document summarizes the key
points of this review for Shell Pipe Line Corporation's (SPLC)
demonstration project, and evaluates the safety and environmental
impacts of this proposed project.
This document was prepared in accordance with section 102(2)(c) of
the National Environmental Policy Act (42 U.S.C. 4332), the Council on
Environmental Quality regulations (40 CFR 1500-1508), and Department of
[[Page 7501]]
Transportation Order 5610.1c, Procedures for Considering Environmental
Impacts.
B. Description of the Proposed Action
As a result of a comprehensive review of the risk management
demonstration project SPLC proposed, the Office of Pipeline Safety
(OPS) proposes to approve this project for participation in the
Demonstration Program.
The SPLC project would involve two pipeline segments:
(1) Texas-Louisiana 12'' Ethylene Pipeline System--205 miles of 250
mi. (Within the States of Texas and Louisiana); and
(2) Cortez 30'' Carbon Dioxide (CO2) Pipeline System--260 miles of
502 mi. (Within the States of Colorado and New Mexico).
A full description of the scope of this project appears in 62 FR
67932.
The OPS Project Review Team that conducted this review has
concluded the SPLC project will:
1. Provide superior safety and environmental protection for both of
the pipeline segments proposed for the demonstration project; and
2. Offer a good opportunity to evaluate risk management as a
component of the Federal pipeline safety regulatory program.
The Project Review Team evaluated the project according to review
protocols and criteria. This evaluation is documented in ``OPS Project
Review Team Evaluation of Shell Demonstration Project.''
As a candidate for the Pipeline Risk Management Demonstration
Program, SPLC conducted a thorough and systematic risk assessment to
identify hazards and risks associated with operating both demonstration
segments. This risk assessment is described in ``OPS Project Review
Team Evaluation of Shell Demonstation Project''. Teams of SPLC
personnel representing each demonstration pipeline system, and
possessing an average of over 25 years of expertise in pipeline design,
construction, operations, and maintenance, performed the assessments.
These assessments confirmed expectations that the greatest risk to both
segments is damage by third party excavation activities near the
pipelines.
To control this risk, the SPLC teams identified a number of new
preventative measures, as well as the enhancement of several existing
activities, to address both identifying the possibility of the
existence of any past excavation-related damage and the prevention of
any future damage of this type. These risk control activities include:
Right of Way Surveillance:
Increasing the frequency of air patrols beyond 26 per
year.
Improving the timeliness and effectiveness of air patrol
reporting.
Improving line-riding procedures and plans.
Defining and implementing improved patrol activities at
critical locations.
Pipeline Locating:
Evaluating the need for additional and/or improved style
of line markers.
Labeling line markers with locating information.
Installing vehicle barriers where above-ground facilities
are near roads (Texas--Louisiana line only--no such equipment exists on
the Cortez system.).
Installing warning mesh prior to backfilling when the line
is exposed for construction.
Conducting annual depth of cover surveys at road crossings
on the Cortez system; evaluating the need for such surveys on the
Texas--Louisiana line.
Furthering company involvement in and sponsorship of One-
Call programs.
Improving procedures and resources for communicating
requirements for and managing third party crossings of the lines.
Public Awareness and Education:
Conducting dispersion modeling and utilizing the results
in improving emergency response plans and drills, and targeting
recipients of pipeline safety mailings.
Providing improved maps and user-friendly information to
emergency responders.
Developing a ``Good Neighbor Plan'' to increase public
awareness.
Improving existing repair (emergency response) plans and
procedures.
Conducting simulated release drills with emergency
responders, and updating the Facility Response Plan manual.
Conducting a corporate-wide workshop on best practices.
Except as noted above, these activities will be performed on both
demonstration segments. In addition, for the Texas--Louisiana line,
SPLC will conduct an internal inspection using a geometry/smart pig and
compare the results with recent Close Interval Survey results to
determine if there are any instances of prior unknown third party
damage. For the Cortez system, SPLC will conduct a Close Interval
Survey over the entire demonstration segment with emphasis on
determining if prior third party damage has occurred. All of the risk
control activities proposed by SPLC exceed regulatory requirements.
The OPS Project Review Team has reviewed these risk control
activities and believes that significant improvements in Right-of-Way
surveillance, pipeline locating, public education and awareness, and
identification of the possibility of unknown past third party damage
will result from this project. In addition, emergency preparedness
would be improved through increased communications with local emergency
responders, including the conduct of drills and the sharing of
information from release modeling.
SPLC has also identified performance measures to monitor the
effectiveness of these risk control activities throughout the life of
the demonstration project to ensure that the desired outcome of
improved protection is achieved. Measures have also been established to
evaluate the institutionalization of risk management within SPLC. The
performance measures will form the basis for OPS audits of
demonstration project effectiveness.
For the Texas-Louisiana 12'' Ethylene Pipeline System, no
regulatory exemptions are being sought. The company will still be
required to comply with all of the applicable requirements of 49 CFR
part 195. In addition, the new and enhanced risk control activities to
address third party damage risks will be implemented as noted above.
For the Cortez 30'' Carbon Dioxide Pipeline System, relief from the
maximum operating pressure requirement of 49 CFR 195.406 (a)(1-3) over
a 25-mile segment immediately downstream of the Cortez Station--all of
which is located in a rural and sparsely populated area--is being
sought under this program. This regulatory requirement remains in full
force over the remainder of the Cortez system, and all other applicable
Part 195 requirements remain in full force for the entire pipeline.
SPLC conducted several technical evaluations to demonstrate the safety
of operating the initial 25 miles at the higher pressure. Furthermore,
the installation of redundant over pressure protection systems, risk
control activities to ensure the existing integrity of line, and safety
precautions taken prior to increasing pressure will further minimize
the risk associated with the increased operating pressure.
In addition to the risk control activities implemented to minimize
the risk associated with increasing the Cortez Station discharge
pressure, SPLC will implement the previously mentioned risk control
activities to address past and future third party damage over the
entire 260 mile Cortez demonstration segment. In addition, over the
initial 25 miles downstream of
[[Page 7502]]
the Cortez Station, a depth of cover survey will be conducted and
correlated with the Close Interval Survey results to help identify if
there is any past third party damage.
The SPLC demonstration project does not involve the construction of
any new pump station or pipeline. The increased operating pressure will
be accomplished by making modifications to the existing Cortez Pump
Station. In fact, with the flexibility to raise pressure above
regulatory limits, SPLC can increase throughput (the amount of
commodity transported) without having to construct an intermediate pump
station near Blanco, NM. Such a project would involve major new
construction, including bringing utilities to a relatively remote site.

risk assessment, and the OPS rationale for approving the project, are

C. Purpose and Need for Action
As authorized by Congress, OPS is conducting a structured
Demonstration Program to evaluate the use of a comprehensive risk
management approach in the operations and regulation of interstate
pipeline facilities. This evaluation is being performed under strictly
controlled conditions through a set of demonstration projects being
conducted with interstate pipeline operators. Through the Demonstration
Program, OPS will determine whether a risk management approach,
properly implemented and monitored through a formal risk management
regulatory framework, achieves:
(1) Superior safety and environmental protection; and
(2) Increased efficiency and service reliability of pipeline
operations.
In May, 1997, SPLC submitted a Letter of Intent to OPS, asking to
be considered as a Demonstration Program candidate. Using the
consultative process described in Appendix A of the Requests for
Application for the Pipeline Risk Management Demonstration Program (62
FR 14719), published on March 27, 1997, OPS is satisfied that SPLC's
proposal will provide superior safety and environmental protection, and
is prepared to finalize the agreement with SPLC on the provisions for
the demonstration project.
D. Alternatives Considered
OPS has considered two alternatives; approval or denial of the SPLC
demonstration project.
OPS's preferred alternative is approval of the SPLC demonstration
project. OPS is satisfied that the proposal provides protection for
both of the demonstration segments. For the Texas-Louisiana ethylene
line, all of the proposed risk control activities go beyond the current
regulatory requirements and thus provide a higher level of protection
than exists today. OPS and SPLC will monitor and, if necessary, improve
the effectiveness of the risk control activities throughout the
demonstration period.
For the Cortez line, OPS is satisfied that the safety margin in the
pipe can accommodate the proposed increase in pressure without adding
significant additional risk to the public. Furthermore, SPLC has
adequately demonstrated that the combination of third party damage and
other risk control activities described earlier more than offset any
increase in risk associated with the higher operating pressure in the
first 25-miles of the line. If OPS does not approve the SPLC
demonstration project, SPLC plans to construct a pump station near
Blanco, NM, to achieve increased throughput on the Cortez line without
raising pressure beyond regulatory limits. The construction site would
be located in desert terrain, would cover approximately three acres,
and would require a new right-of-way for the installation of nine to
ten miles of electric transmission line.
E. Affected Environment and Environmental Consequences
The two pipelines proposed for this demonstration project transport
distinctly different products that represent very different hazards.
The Texas-Louisiana line transports chemical-grade ethylene, a
flammable, highly volatile liquid that becomes a slightly lighter-than-
air gas when released to the atmosphere. Under certain conditions, it
could form an explosive vapor cloud until diluted or dispersed. The
only potential environmental impact of an ethylene release would be the
localized damage created by a fire or explosion in the vicinity of the
release. Because of its volatile nature, ethylene is not considered a
water pollutant. The Cortez system transports commercial grade carbon
dioxide. Carbon dioxide is a naturally occurring component of air and
presents no environmental hazard. However, at high concentrations in
confined, low lying areas, it could represent an asphyxiation hazard
until it is dispersed or diluted.
During the course of the consultation, SPLC presented the results
of their risk control and decision support process that identified the
risk control activities they propose to implement on the Cortez and
Texas-Louisiana systems. The OPS Project Review Team carefully reviewed
these activities and concluded that superior protection would be
provided for both pipeline systems.
For the Texas-Louisiana Ethylene System, SPLC has not requested any
exemptions or variances from the existing regulations. The risk
assessment for the Texas-Louisiana system identified damage from third
party excavation activities as the most significant contributor to
potential pipeline ruptures and leaks. This conclusion is supported by
the operating history of this system.
To address these third party damage risks, SPLC proposes to
implement a number of risk control activities (mentioned previously).
The OPS Project Review Team reviewed the Texas-Louisiana risk control
activities during the consultation process and provided input that
helped define the final set of activities. As stated previously, all of
these risk control activities go beyond the existing regulations in
providing additional assurance of safety. The OPS review included an
examination for potentially negative, unintended outcomes from the
proposed activities: No significant negative impacts were identified.
OPS has concluded that the risk control activities listed above when
combined
[[Page 7503]]
with the existing company practices (which comply with and in some
cases exceed 49 CFR part 195 requirements) will reduce the likelihood
of pipeline accidents and leaks on the Texas-Louisiana Ethylene System.
The insights from the dispersion analysis and the improvements to the
emergency response plans and drills should improve the responsiveness
of the company and local officials to an event, should a leak or
rupture occur. Thus, the consequences of a leak or rupture should be
diminished. In summary, based on expected reductions in both the
likelihood and consequences of leaks and ruptures, OPS has concluded
that the proposed risk control activities will clearly reduce safety
and environmental risks on the Texas-Louisiana system.
For the Cortez Carbon Dioxide system, the only activity SPLC
proposes to take that would increase risk is increasing the operating
pressure downstream of the Cortez pump station. For the initial 25
miles, the pressure might be increased by up to 11% above the limit
currently established by the regulations. SPLC has conducted several
technical evaluations to demonstrate that it could safely operate the
pipeline at the higher pressure over the initial 25 mile segment.
Furthermore, the installation of redundant over pressure protection
systems, risk control activities to ensure the existing integrity of
line, and safety precautions taken prior to and during the increase in
pressure will minimize any risk associated with the increased operating
pressure.
The risk assessment for the Cortez system identified damage from
third party excavation activities as the most significant contributor
to potential pipeline ruptures and leaks. To address these risks, SPLC
proposes to implement a number of risk control activities (mentioned
previously). The OPS Project Review Team reviewed the Cortez risk
control activities during the consultation process and provided input
that helped define the final set listed previously. This review
included an examination for potentially negative, unintended outcomes
from the proposed activities. No significant negative impacts were
identified.
The PRT has concluded that the risk control activities listed above
when combined with the existing company practices (which comply with
and in some cases exceed 49 CFR part 195 requirements) will reduce the
likelihood of third party damage related events on the Cortez system
(the most significant risk to the system). The activities designed to
identify instances of prior third party damage should increase the
likelihood that prior unknown damage, if any, will be detected and
remediated. These activities should minimize the likelihood that any
such damage will result in leaks or ruptures at the higher operating
pressure. OPS believes that this combination of risk control activities
will reduce the likelihood of a Cortez system leak or rupture and more
than offset the small increase in likelihood of line failure associated
with higher operating pressure.
The insights from the dispersion analysis, the improvements to the
emergency response plans and drills, and field personnel training
should improve the responsiveness of the company and local officials to
an event, should a leak or rupture occur. Thus, the consequences of a
leak or rupture should be diminished. In summary, based on expected
reductions in both the likelihood and consequences of leaks and
ruptures, OPS concludes that the combination of risk control activities
in conjunction with the increase in operating pressure by no more than
11% over the first 25 miles will result in superior protection of the
public.
F. Environmental Justice Considerations
In accordance with Executive Order 12898 (Federal Actions to
Address Environmental Justice in Minority and Low-Income Populations),
we have considered the effects of the demonstration project on minority
and low-income populations. As explained above, OPS believes this
project will provide superior safety and environmental protection along
both demonstration project lines. The pipeline segments proposed for
the project are routed through rural, sparsely populated, industrial
and developing residential areas. A mixture of income levels resides
along the segments. The risk control activities provide greater
protection than mere compliance with existing regulations. Because risk
management activities will be applied uniformly along both lines,
residents and communities near each line will be afforded greater
protection than they presently have, regardless of the residents'
income level or minority status. Therefore, the proposed project does
not have any dispropotionately high or adverse health or environmental
effects on any minority or low-income populations along the
demonstration segments.
G. Information Made Available to States, Local Governments,
Individuals
OPS has recently (in January and February 1998) made the following
documents publicly available, and incorporates them by reference into
this environmental assessment:

(2) ``Demonstration Project Prospectus: Shell Pipe Line
Corporation'', January 1998, available by contacting Elizabeth M.
Callsen at 202-366-4572. Includes maps of the demonstration segments.
Purpose is to reach the public, local officials, and other
stakeholders, and to solicit their input about the proposed project.
Mailed to over 500 individuals, including Local Emergency Planning
Committees (LEPC) and other local safety officials, Regional Response
Teams (RRT) representing other federal agencies, state pipeline safety
officials, conference attendees, and members of public interest groups.

OPS has previously provided information to the public about the
SPLC project, and has requested public comment, using many different
sources. OPS aired three electronic broadcast (June 5, 1997; September
17, 1997; and December 4, 1997) reporting on demonstration project
proposals (including SPLC's proposal). Two earlier Federal Register
notices (62 FR 40135; July 25, 1997 and 62 FR 53052; October 10, 1997)
informed the public that SPLC was interested in participating in the
Demonstration Program, provided general information about technical
issues and risk control alternatives to be explored, and identified the
geographic areas the demonstration project would traverse.
Since August, OPS has used an Internet-accessible data system
called the Pipeline Risk Management Information System (PRIMIS) at
http://www.cycla.com/opsdemo to collect, update, and exchange
information about all demonstration candidates, including SPLC.
At a November 19, 1997, public meeting OPS hosted in Houston, TX,
SPLC officials presented a summary of the proposed demonstration
project and answered questions from meeting attendees. (Portions of
this meeting were broadcast on December 4, 1997. This
