Work Experience
Interstate Commerce Commission
I spent most of my government career at the Interstate Commerce Commission. Fresh out ofLaw School, I served eight years there advancing from Staff Attorney to Principal Attorney, toAdvisor to one Commissioner, then Chief of Staff to another Commissioner and finished byheading the office that was responsible for economic regulation of railroads, trucks, buses andbarges throughout the United States. My second stint included service as Head of the MotorCarrier Section and Deputy General Counsel in charge of regulatory development. Betweenthose two Senior Executive positions, I served a detail of six months in the Office of PresidentialPersonnel advising on individuals to fill positions on Boards and Commissions throughout thegovernment.
Transamerica Interway
I served as Vice President Government Affairs and Head of the Washington, D.C. Office for thesubsidiary of Transamerica Corporation that owned the largest fleet of ocean going containersand piggyback trailers in the world. I represented the Company before Executive Departments,the Congress and the Courts on legal and regulatory issues.
Arnall, Golden & Gregory
I was a Partner in the Washington, D.C. office of this Atlanta law firm. Our office specialized intransportation and safety matters before Congress, the Regulatory Agencies and ExecutiveDepartments. During that time I also taught regulatory management focused on surfacetransportation at the graduate business school of the University of Wisconsin and later taught apipeline seminar in a similar graduate program at Northwestern University. I published articlesin the Harvard Business Review and a number of transportation periodicals, and I testified manytimes before the Congress, the National Transportation Safety Board and regulatorycommissions on various transportation and safety issues.

Office of Pipeline Safety, U.S. Department of Transportation
I ran the Office of Pipeline Safety from 1995 to 2000, where I had responsibility for the safe andenvironmentally sound operation of all pipelines in this country. In 1998 I received the SeniorExecutive Service Presidential Rank Award for my design and implementation of the FederalPipeline Safety Program. Under my leadership, the Office of Pipeline Safety changed the wayregulatory and enforcement resources were allocated to pipeline risks and devised moreeffective regulatory and enforcement strategies to address the highest risks. I created the firstPipeline Risk Management Demonstration projects and spearheaded the development ofPipeline Integrity Management. I also convened a Damage Prevention Quality Action Team thatdesigned the "Dig Safely" public education campaign for protecting all buried utilities.
Common Ground Alliance
The leading cause of pipeline accidents is excavation and construction damage. When I joinedthe Office of Pipeline Safety almost no resources were being devoted to this problem, and stateand local efforts were largely ineffective. I organized the Common Ground study in response toa request from Congress to identify "best practices" to protect all buried utilities and preventdamage to these important lifelines. I organized 160 working volunteers representing utilities,regulators, one-call centers, and the excavation community to do the study. The studyidentified 132 "best practices" and highlighted the need for improved communications andshared responsibility to prevent property damage and injury to those who live and work aroundburied utilities.
After I left the Office of Pipeline Safety, I spent one year founding and establishing the CommonGround Alliance whose purpose is to extend the work of the Common Ground study andprevent damage to all buried utilities including gas , electric, telecommunications, and waterand sewer lines. Today, the Common Ground Alliance has a 16 member Board of Directors, 7working committees and operates on a budget of contributions from utilities, excavationcompanies and the government. It works to improve safety codes, adopt new safety "bestpractices", promote new technologies, collect excavation damage data and advance publiceducation through the "Dig Safely" advertising message. Most recently, the Common GroundAlliance was the moving force behind the Federal Communications Commission mandating thenationwide 811 call before you dig telephone number. In 2014, I returned to address theCommon Ground Alliance's Annual meeting and was honored by being inducted into theCommon Ground Alliance Hall of Fame.

EXECUTIVE SUMMARY
Virginia Natural Gas’s Southside Connector Distribution Project is designed and will
be constructed to meet or exceed all applicable pipeline safety standards. It will be
operated and maintained to provide the natural gas requirements of the City of
Norfolk safely and reliably. To provide the safest possible route, it will be built in
existing utility right-of-way and use easements on city owned property on land and
on existing easements across the Elizabeth River.
Colonna’s safety concerns are based on a report prepared by R. D. Deaver entitled
“Potential Impacts of the Southside Connector”. Colonna’s safety concerns have
also been reviewed and amplified by another consultant, Richard Kuprewicz.
Kuprewicz also offered a list of “Safety Related Land Use Questions”. Deaver’s
paper and Kuprewicz’s review hinge on certain key assumptions. First, and
foremost, is the mistaken notion that the Federal pipeline safety regulations, 49
CFR Part 192, are formulated as “minimums” and are insufficiently protective of
people and property. Second is an unfounded and unsupported belief that the
Southside Connector is a high-pressure transmission line that is so dangerous that
it can only be effectively regulated if it is subjected to the licensing standards of the
Federal Energy Regulatory Commission (FERC) and measured by “best practices”
for siting such pipelines suggested by FEMA and the Pipeline and Hazardous
Materials Safety Administration (PHMSA) of the U.S. Department of
Transportation. The Kuprewicz Land Use Questions are equally misplaced. There
are local and Federal laws and regulations that answer all of his questions.
The Southside Connector Distribution Project involves constructing the last eight
miles of a two-hundred-mile pipeline between Quantico, VA and Norfolk, VA. We
have examined three years of operating data which conclusively demonstrates that
the pipeline has been and will be operated at pressures which guarantee the
highest possible margin of safety while effectively supplying the energy needs of
Norfolk’s residents and businesses. This data shows that Colonna’s safety concerns
and dire predictions are totally unfounded. VNG has committed to the City of
Norfolk to adhere to this safe operating plan for the Southside Connector.
P a g e | 15
Measured against the Federal pipeline safety regulations, which are the standards
that apply to the design, construction, maintenance and operation of an intrastate
natural gas transmission line, the Southside Connector meets or exceeds the
regulatory requirements. The pipeline will be thoroughly inspected by the Pipeline
Safety Division of the Virginia State Corporation Commission and tested for
possible flaws or imperfections before it is placed in operation. The pipeline will be
maintained and operated under an Integrity Management Plan approved by the
regulators. Finally, the pipeline will be monitored and controlled 24/7, including
the ability to remotely operate shut-off valves. With all these safeguards in place,
the City of Norfolk should feel safe and secure as the final phase of the Southside
Connector Distribution Project is completed.
P a g e | 16
SAFETY ANALYSIS
The Federal pipeline safety regulations are a compendium of best practices and
safety standards tailored to protect people and the environment from potential
risks posed by pipelines. Colonna’s persistent use of the term minimum federal
safety requirements as a pejorative exposes its misunderstanding of how Federal
pipeline safety regulations work. Experts who have the requisite education and
experience working with safety regulatory laws are familiar with using statutory
minimum standards to provide enhanced public protections. A careful reading of
the Federal pipeline safety regulations by Colonna’s consultants would have
answered all of the questions and concerns that they are raising for the first time
as construction is scheduled to begin.
The most serious problem with Colonna’s concerns is the mistaken view that VNG’s
unquestioned compliance with Federal pipeline safety regulations that govern the
safe design, construction, maintenance and operation of the Nation’s pipelines is
not dispositive of Colonna’s safety concerns. They refuse to acknowledge how
these regulations provide the precise protections that they claim can only come
from prohibiting construction in the planned right-of-way. Colonna’s safety
concerns do not address actual deficiencies in the Southside Connector that would
prompt genuine safety issues. Colonna’s expresses fear of a catastrophic failure
which they attribute to what they term unpreventable human errors or “other
causes beyond the control of the utility company in certain pipeline locations”.
Colonna’s also underestimates the value of regulatory compliance by repeatedly,
falsely stating that the Southside Connector suffers from “mere compliance with
minimum federal requirements”
Colonna’s dismissal of Federal pipeline safety standards as insufficient to protect
the public or an inferior substitute for “common sense” pipeline siting is a self-
serving argument that is not supported by the facts. Everyone would agree that you
cannot regulate away all risks but you can manage these risks effectively by
complying with and exceeding Federal pipeline safety regulations. Pipelines are not
P a g e | 17
banned from high consequence areas (HCA). 1 Instead, the regulations call for
pipeline operators like VNG to have an Integrity Management plan to assess and
address pipeline risks in HCAs. Pipelines are not banned from navigable waterways.
The Navy looks to Federal pipeline safety regulations and the Army Corps of
Engineers permitting process for protection.
Finally, Colonna’s devotes considerable attention to a Hazard Mitigation Planning
study jointly developed by FEMA and PHMSA. This is an excellent primer on pipeline
risks. It was written to assist cities trying to understand the best way to work with
high pressure transmission lines regulated by FERC. Again, before citing this study
or referring to horrific accidents on pipelines that bear no relation to the Southside
Connector, Colonna’s needs to point to the design, construction, operating or
maintenance characteristics that support comparing the Southside Connector to
1 HCA definition is: High consequence area means an area established by one of the methods described in paragraphs (1) or (2) as
follows:
(1) An area defined as-
(i) A Class 3 location under §192.5; or
(ii) A Class 4 location under §192.5; or(iii) Any area in a Class 1 or Class 2 location where the potential impact radius is greater
than 660 feet (200 meters), and the area within a potential impact circle contains 20 or more buildings intended for human
occupancy; or
(iv) Any area in a Class 1 or Class 2 location where the potential impact circle contains an identified site.
(2) The area within a potential impact circle containing-
(i) 20 or more buildings intended for human occupancy, unless the exception in paragraph (4) applies; or
(ii) An identified site.
(3) Where a potential impact circle is calculated under either method (1) or (2) to establish a high consequence area, the length of
the high consequence area extends axially along the length of the pipeline from the outermost edge of the first potential impact
circle that contains either an identified site or 20 or more buildings intended for human occupancy to the outermost edge of the
last contiguous potential impact circle that contains either an identified site or 20 or more buildings intended for human
occupancy. (See Figure E.I.A. in Appendix E.)
(4) If in identifying a high consequence area under paragraph (1)(iii) of this definition or paragraph (2)(i) of this definition, the
radius of the potential impact circle is greater than 660 feet (200 meters), the operator may identify a high consequence area
based on a prorated number of buildings intended for human occupancy with a distance of 660 feet (200 meters) from the
centerline of the pipeline until December 17, 2006. If an operator chooses this approach, the operator must prorate the number of
buildings intended for human occupancy based on the ratio of an area with a radius of 660 feet (200 meters) to the area of the
potential impact circle (i.e., the prorated number of buildings intended for human occupancy is equal to 20 x (660 feet) [or 200
meters]/potential impact radius in feet [or meters].

these other pipelines. Colonna’s persists in viewing the Southside Connector as a
high-pressure transmission line of the type that would serve as an interstate facility
delivering large quantities of natural gas at a transfer point at the edge of the city
for subsequent distribution to homes and businesses. It has offered diagrams that
depict large scale fire and blast zones that extend long distances from the pipeline
route. It has distributed videos of highly disturbing scenes following pipeline
ruptures. The FEMA and PHMSA study and the diagrams and videos have no
application to the Southside Connector which will be a component of VNG’s
distribution system.
Colonna’s call for additional study and delay is supported by a list of supposed
shortcomings in the Federal pipeline safety regulations. One complaint is that the
regulations do not control the location of pipelines and do not require operators to
follow best safety practices. In fact, the regulations use a combination of well-
defined class locations, material and construction standards that tell an operator
how it must build in a particular location which effectively establishes where the
operator can build. As far as best practices are concerned, the regulations are a
comprehensive set of standards for design, construction, maintenance and
operation of natural gas pipelines. Their origin was various codes developed by
consensus standards organizations like the National Association of Corrosion
Engineers, the American Society of Testing and Materials and many others. These
codes are recognized throughout this country and the world as the product of
subject matter experts from industry, academia and regulatory bodies. The
regulations have been revised and improved over 120 times to incorporate evolving
changes in technology and regulatory innovations. The regulations are not
minimums from a safety perspective. They are only termed minimums because
operators are obligated to meet or exceed them. Everyone, including the shipyard,
agrees that the Southside Connector complies with the regulations. We will explain
how the pipeline not only meets but also exceeds regulatory requirements in many
important areas.
A good starting point for a valid safety assessment of the Southside Connector is
the fact that it exceeds federal safety standards in several important areas including
P a g e | 19
the pipeline’s wall thickness and burial depth. 2 Importantly, the pipeline is
designed to be built in areas that are heavily populated and contain multi-story

practices).
(f) All pipe installed offshore, except in the Gulf of Mexico and its inlets, under water not more than 200 feet (60 meters)

installed with a minimum cover of 36 inches (914 millimeters) in soil or 18 inches (457 millimeters) in consolidated rock
between the top of the pipe and the natural bottom.
(2) Pipe under water at least 12 feet (3.66 meters) deep must be installed so that the top of the pipe is below the natural
bottom, unless the pipe is supported by stanchions, held in place by anchors or heavy concrete coating, or protected by
an equivalent means.

accordance with §192.612(b)(3).

buildings; so-called Class 4 locations. Thus, if additional development takes place
along the pipeline route, protections are already built in.
Rather than evaluate whether the Southside Connector complies with applicable
safety standards, Colonna’s offers a list of potential pipeline failures but makes no
effort to examine how the Southside Connector is designed to minimize or
eliminate the risk of these types of failures. For example, to address the risk of
manufacturing defects or welding flaws, before the pipeline is placed in service,
VNG plans to pressure test the pipeline to 90% SMYS. A baseline internal inspection
by “smart pigs” will be run to evaluate any problems that may pose a safety risk to
the pipeline. In other words, both the strength of the pipe and the construction of
the pipeline will be safety checked before it ever operates. In addition, the pipeline
is designed to be periodically tested with “smart pigs” to detect any defects like
dents, gouges, cracks or wall thinning after the line is placed in operation. Also, on
Colonna’s list of potential failure modes is internal or external corrosion. Of course,
VNG’s design specifications include external coating and a cathodic protection
system to prevent and monitor external corrosion. Any internal corrosion will be
spotted by the aforementioned internal inspections. In addition, zinc ribbon
cathodic protection has been designed into the pipeline to mitigate induced AC
current and stray DC current which might interfere with cathodic protection levels
already required by regulation. Likewise, there is no recognition of VNG’s damage
prevention program or its plan to spend extra dollars to use existing right-of-way
to minimize the potential for excavation damage. Colonna’s approach of simply
listing failure modes without any examination of VNG’s plans and ongoing actions
to address these potential risks was not helpful.

SAFETY ASSESSMENT
First let’s clarify what this pipeline really is. The “Transmission Line” definition
found in Part 192 - Transportation of Natural and Other Gas by Pipeline Minimum
Federal Safety Standards states:
Transmission Line means a pipeline, other than a gathering line, that:
(1) Transports gas from a gathering line or storage facility to a [gas] distribution center,
storage facility, or large volume customer that is not down-stream from a [gas]
distribution center; (2) operates at a hoop stress of 20 percent or more of SMYS; or (3)
transports gas within a storage field.
The Southside Connector is a pipeline covered under the Federal and State
regulations because it is an Intrastate Transmission Line that operates at a hoop
stress of 20 percent or more of SMYS (specified minimum yield strength).
Colonna’s likes to describe the pipeline as a high-pressure transmission line. As
designed, the line will be constructed of API 5L X65 steel .500 wall thickness and
operated with an MOP (Maximum Operating Pressure) from 500 to 1000 psig. This
combination of material strength and operating pressure produces a stress level on
the pipe of 18% to 37% SMYS (specified minimum yield strength) which is at times,
less than the 20% SMYS definition for transmission and is considered to be
distribution pressure. This means that even though the pipeline meets the technical
definition of a transmission line, it will be operated way below allowable
transmission pressure. Using stronger steel and lower operating pressure
mathematically aids in eliminating the chance of a rupture. Industry groups and
academics have studied the stress levels on a pipeline facility, and over the years,
has found any pressures below 30% SMYS will leak before rupture. When a pipeline
is operated at low pressures that will produce a leak before a rupture in the event
of a material failure, the potential for a rupture and explosion is eliminated, and
the pressure drop occasioned by the leak can be detected and the leak can be
repaired. A table to follow will show the stress levels in more detail and will show
the overdesign safety levels adopted by VNG.
To confirm that the design and proposed operating plan for the pipeline are
realistic and attainable, we examined three years of operating history of the other
90 % of the pipeline that is already in service. In particular, we looked at the inlet
P a g e | 22
pressure readings for the Salter Street Station which is the northern connection of
the Southside Connector. The results should provide real comfort to the City of
Norfolk. 97% of the operating hours were below 813 PSIG which is the 30% SMYS
level. 58% of the operating hours were below 541 PSIG. Which is the 20% SMYS
level. At no time did the pipeline exceed the maximum allowable operating
pressure of 1250 PSIG. These numbers show that the safe design and operation of
this pipeline is assured.
This line is monitored by the State of Virginia Pipeline Safety Division through an
agreement with the Federal Government. DOT has an agreement with the State of
Virginia to inspect and enforce the regulations on intrastate facilities. This
Federal/State partnership program has been in existence since 1968 based on the
Congressional mandate, requiring the U.S. Department of Transportation (DOT) to
develop a set of pipeline safety regulations (CFR 49 Part 192). There are 52 State
entities that have agreements with DOT to enforce the Federal regulations. FERC
does not regulate intrastate transmission pipelines.
Design of the pipeline facility is required to follow specific “parts,” “subparts,”
“sections” and “appendices” of the regulations dealing with all aspects of design,
construction, operation, corrosion, welding, maintenance, and emergency
response of pipe and appurtenances. For placement of a pipeline (intrastate
transmission line) a pipeline operator must design and comply with subparts “A,”
“B,” “C,” “D,” “E,” “G,” “I,” “J,” “L,” “M,” “N,” “O,” “P,” and Appendices “B,” “D,”
and “E.” The starting point is determining class location of the pipeline that is to
be constructed. This will drive all other areas of consideration such as: material
selection (pipe), components (valves, flanges, etc.), welding, maximum allowable
operating pressure (MAOP), maximum operating pressure (MOP), corrosion,
testing, regulator & relief, metering, employee qualification, integrity
management, smart-pigging, etc.
The Southside Connector pipeline facility is in a Class 3 area; therefore, pipe and
appurtenances must comply with this specific class location. Because of the entire
facilities being in a Class 3 HCA, the requirements are applicable for the entire
length of the facilities. It should be noted that VNG design engineers and consulting
P a g e | 23
engineers chose to design and build a pipeline facility comparable to a Class 4
pipeline facility, making these facilities safer than Federal regulations would
require. This involved more cost and effort on VNG’s part but was designed to
promote pipeline safety for their customers and the general public. Building in Class
4 protections also accommodates future development along the pipeline without
having to make safety adjustments to the pipeline. This is all part of VNG’s plan to
fulfill its obligation as a public utility in the safest possible way.
Let’s talk more specifics about the Southside Connector. Pipe that will be used to
construct this pipeline will meet API Specification 5L, “Specification for Line Pipe,”
45th edition, effective July 1, 2013, (API Spec 5L), IBR approved for
§§192.55(e); 192.112(a), (b), (d), (e); 192.113; and Item I, Appendix B to Part 192.
The pipeline will be constructed below 50% SMYS which is comparable to a Class 4
pipeline. Designing the pipeline with the intention of always operating at less than
half of the MAOP (maximum allowable operating pressure) offers an exceptional
margin of safety. The pipeline will be constructed of API 5L X65 steel 24” pipe with
a wall thickness of .500. Applying the design formula from §192.105, the SMYS
levels that will be obtained are shown in the table below. What this really means is
that VNG has built in a very wide margin of safety by using stronger pipe and
operating it at highly reduced pressure shown in the bottom line of the chart. The
leak before failure potential is not reached until the pressure exceeds 812 PSIG at
30% SMYS. VNG has exceeded the Federal Regulations in several areas. Some of
these added safety areas are addressed in the following SMYS table.

Pipeline efforts to exceed Federal Pipeline Regulations
Pipe Material: Higher strength steel pipe than required – API X65 steel pipe was
selected so %SMYS at MAOP is 46%. Code would have allowed API – X60 pipe to
be used making the %SMYS at 50%.
Valve Spacing: CFR 49 192.179 addresses valve requirements. The Southside
Connector pipeline is an 8.1-mile facility and it could have been built as a Class 3
pipeline in accordance with Federal regulations with valve spacing 4 miles apart
and with manually operated valves. As designed there will be shutoff valves at
Salter Street, Chesapeake Gate Station and DD Jones Property (Berkley Ave). Each
location on the pipeline is within 2½ miles of a remote-control valve (RCV). Spacing
for a Class 4 facility is: Each point on the pipeline in a Class 4 location must be
within 2½ miles (4 kilometers) of a valve. All shutoff valves will be remotely
operated and monitored 24/7/365. In other words, valve number, type and spacing
all exceed the regulatory requirements.
Cathodic Protection System: Sacrificial anodes (magnesium and/or zinc ribbon)
will be used along the pipeline to provide cathodic protection to the VNG pipeline
facilities to minimize interference problems (stray DC and induced AC interference)
from nearby facilities (ship yards [Colonna], railroad, telephone cable, power lines
and other facilities emitting DC current). Zinc ribbon will be installed along the side
of the pipeline to drain off, mitigate interference problems and protect coating.
This addresses the shipyard’s concerns about how the pipeline will be protected
from the high-powered electrical equipment used in ship construction.
Construction Inspection: VNG hired an independent third-party inspection agency
to monitor all construction activity. This is not required by Federal regulations. VNG
continues to use their employees to inspect along with the State Corporation
Commission Pipeline Safety Division inspectors, who have inspected the pipeline
more than 45 times.
All production welds will be nondestructively inspected using qualified personnel
to visually inspect and will be 100% x-rayed to ensure all critical anomalies are
found and repaired before placing the Southside Connector pipeline into service.
P a g e | 25
All pipe and materials were inspected and approved by a third-party metallurgical
engineering firm. All company employees, third-party inspectors and contractor
personal are operator qualified in accordance with the regulations in Part 192
Subpart “N.”
VNG will do an in-service in-line inspection (smart-pig) run at conclusion of
construction. Regulations would only require a run within a 10-year interval from
completion of the project.
Periodic Inspections / Maintenance: There will be annual regulator and relief valve
station inspections in accordance with CFR 49 §192.739 Pressure limiting and
regulating stations: Inspection and testing. There will be bi-weekly roadway
crossing inspections which exceeds regulations. There will be monthly aerial
patrols of rights-of-ways (ROWs) exceeding regulations. There will be quarterly
readings of cathodic protection (CP) test sites and monitoring and review of AC
mitigation systems which are over and above what regulations would require
(found in Subpart “I” and CFR 49 §192.465). Each pipeline that is under CP must be
tested at least once each calendar year, but with intervals not exceeding 15
months, to determine whether the CP meets the requirements (again more
frequent evaluation of cathodic protection system to promote safety).
Safety Oversight after Construction is Completed
The Deaver report states that there are no pipeline safety “police” to prevent
operators from shaving costs to reduce safety. He also believes that penalties for
non-compliance are minimal. In fact, PHMSA has a nationwide enforcement staff
overseeing interstate operators supported by State pipeline safety offices to
monitor intrastate operators. As noted before, the Southside Connector has been
inspected during construction and operation over 45 times. Indeed, Virginia has
signed an agreement with PHMSA that requires an inspection and enforcement
effort that assures that pipeline operators meet or exceed Federal safety standards.
The statutory penalties for violating pipeline safety requirements are set at up to
$200,000 per infraction and can run into millions of dollars for serious findings of
non-compliance.
P a g e | 26
The Deaver report faults the regulations for being vague and general in setting
standards for safety activities. He expresses a preference for regulations that
specify “how to perform” safety activities. Again, this demonstrates his limited
knowledge of the whys and wherefores of natural gas safety regulation. Regulators
always have a choice between using performance standards or prescriptive
requirements. Prescriptive requirements are chosen when there is only one
preferred method to accomplish a safety task. Performance standards are
appropriate for the infinite variety of natural gas facilities where one size does not
fit all. Differing climates, soil conditions and operating environments demand
tailored solutions, not cookie cutter approaches. The suggestion that allowing
operators to determine how best to comply with a performance standard is
somehow a free pass or poor regulatory policy is not true.
Finally, the Deaver report has a strong preference for local control rather than
Federal oversight. It fails to realize that PHMSA oversight delivers the best of both
worlds. The Federal regulatory program can access best practices from all sources.
The regulations are adopted and updated through a process that allows maximum
public participation and review by carefully selected pipeline safety advisory
committees. These are the regulations applied and enforced in the State of Virginia
by the State Corporation Commission’ s Pipeline Safety Division. The licensing
standards of FERC do not apply nor do the advisory recommended practices
developed jointly by the DOT and FEMA as required by the 1992 Pipeline Safety
Improvement Act. In addition, U.S. Environmental Protection Agency (EPA) risk
management regulations do not apply to the operation of this pipeline. The reason
that these other regulatory requirements do not govern the design, siting or
operation of the Southside Connector is obvious. There is already a comprehensive
set of safety regulations, designed specifically to protect people and the
environment from any and all risks posed by natural gas pipelines.
When the Deaver report and Kuprewicz’s review shifts focus from the regulations
to the pipeline itself, the big problem is the pipeline they condemn as an inherently
dangerous, high-pressure gas transmission pipeline does not match the Southside
Connector that VNG designed or plans to operate. Their assumptions about how
the pipeline will inevitably rupture at the maximum allowable operating pressure
P a g e | 27
due to human error or some other cause beyond the control of the operator has
no basis in the actual proposed design, construction, maintenance plan and
operation of the Southside Connector.
Colonna’s acknowledgement that the Southside Connector meets the
requirements of Federal pipeline safety regulations and insistence on confining
their safety concerns to a non-existent high-pressure transmission line makes their
safety concerns ring hollow. Nothing Colonna’s says detracts from our carefully
researched and well documented assessment of the safety profile of the Southside
Connector.
The balance of our assessment will concentrate on why we believe the Southside
Connector is designed to operate safely in Norfolk. We understand that the Navy
has no concerns about the safety of the pipeline. The Navy rightfully relies on
Federal pipeline safety regulations and the Army Corp of Engineers to protect their
interests. In addition, we will explain how the design and proposed operation of
the pipeline should not interfere with future development along the carefully
chosen right-of-way.
Virginia Natural Gas has been working with Colonna’s for approximately 2 years on
the alignment of the Southside Connector. The pipeline is designed to exceed
Federal safety requirements in many ways, and they have communicated that to
Colonna’s Shipyard.
We learned that VNG consultants conducted a route survey that examined five
alternative routes. The route finally selected was based on the safest route for both
construction and on-going maintenance and operation of the pipeline. Cost was
not the main driver. The route selected was priced approximately $8 million higher
than the next alternative.
Regarding the alignment of the Elizabeth River Crossing, VNG is collocating the
Southside Connector within two existing easements – a water pipeline and an 80
ft. City of Norfolk easement. The Southside Connector will not impose any
additional restrictions on future development.
P a g e | 28
VNG designed the Southside Connector pipeline under the Elizabeth River, and
Colonna’s Shipyard, at a depth that far exceeds Federal requirements. HDD
(Horizontal Directional Drilling) drilling the pipeline at these depths (70’ to 90’ plus
feet deep or more) will preserve the navigational channels and not limit the
region’s ability to dredge the channel to greater depths. Additionally, the HDD will
prevent any operational or surface impacts at Colonna’s Shipyard. The HDD will
begin at Harbor Park, continue underneath the shipyard, and resurface on the City
of Norfolk right-of-way.
Lastly, Colonna’s is misinformed regarding VNG’s plans to install shutoff valves
along the line. VNG will have one at each end and one approximately in the center.
In fact, the spacing of these valves not only exceeds Federal requirements but also
includes remote shutoff capability that is monitored 24/7/365.
One final note about Kuprewicz’s list of land use questions. They are either fully
addressed in existing laws and regulations or are related to the FEMA/PHMSA
guidelines for FERC regulated intrastate transmission lines that have no application
to the Southside connector. Three of his questions relate to selecting the
appropriate depth of cover for the pipeline. That subject is covered by Federal
pipeline safety regulations and the Southside Connector exceeds the requirements.
There is a question about terrorist threats but it is generally accepted that such
threats are limited to above ground facilities that are not an issue for this project.
Most of the questions raise damage prevention, construction or zoning issues. The
simple answer to these questions is that there is no reason to treat this project
differently from any other structure or utility. The federal pipeline safety
regulations and local laws address every one the questions he raises. The remaining
questions concern conditions in the existing right-of-way that might affect the
pipeline. These have been addressed in VNG’s plans and will continue to be
addressed in construction which will be overseen by the State Corporation
Commission’s Division of Pipeline Safety.

CONCLUSIONS
VNG has complied with all applicable regulations (CFR 49 Part 192) and
incorporated by reference industry standards (API, ASME, ASTM, GTI, MSS, NACE,
NFPA, ANSI, PRCI, and AGA). Pertinent industry standards can be found in CFR 49
Part 192.7. Construction of the pipeline should not interfere with any present or
future plans to develop property along the right of way because of the design,
operating and maintenance standards followed by VNG. The margin of safety built
into the design, construction, proposed operation and scheduled maintenance of
this pipeline provide maximum protection to the City of Norfolk. We are available
to address any additional questions or concerns you might have.
