Mr. Fred Storer

Reference No. 24-0018
Dear Mr. Storer:
This letter is in response to your February 6, 2024, letter and correspondence with the Pipeline
and Hazardous Materials Safety Administration (PHMSA) requesting clarification of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the definition of
“private track.
” The HMR defines “private track” in § 171.8 as: (1) track located outside of a
carrier’s right-of-way, yard, or terminals where the carrier does not own the rails, ties, roadbed,
or right-of-way; or (2) track leased by a railroad to a lessee, where the lease provides for, and
actual practice entails, exclusive use of that trackage by the lessee and/or a general system
railroad for purpose of moving only cars shipped to or by the lessee, and where the lessor
otherwise exercises no control over or responsibility for the trackage or the cars on the trackage.
You present two different scenarios concerning the determination of “private track” in
accordance with the definition provided in § 171.8.
Q1. In the first scenario (i.e., the Downtown location), the South Kansas and Oklahoma
Railroad (SKOL Railroad)—i.e., the lessor—leases track to Centennial Energy (i.e., the
lessee) for a butane transloading operation. The transloading of the butane is conducted
with no intervention or oversight by SKOL Railroad, and SKOL Railroad exercises no
control or responsibility over the trackage or rail cars involved in the butane transloading
operation—all of which is exclusively carried out by Centennial Energy. You ask
whether this scenario would meet the definition of “private track” in § 171.8.
A1. Based on the scenario as described in your letter, the answer is yes. As previously stated,
one part of the definition for “private track” in § 171.8 is a track leased by a railroad (i.e.,
SKOL Railroad), to a lessee, (i.e., Centennial Energy), where the lease provides for, and
in practice entails, exclusive use of that trackage by the lessee for the purpose of moving
only rail cars shipped to or by the lessee, and where the lessor otherwise exercises no
control over or responsibility for the trackage or the cars on the trackage. Therefore,
based on the scenario described in your letter, it is the opinion of this Office that the
scenario at the Downtown location meets the definition of “private track” in § 171.8.
Q2. In the second scenario (i.e., the East Pine location), butane is shipped by BNSF Railway,
Inc. directly to US Rail and Logistics (USRL). As presented in your letter, the
transloading of the butane occurs exclusively on track owned by BNSF. Furthermore,
your letter states that BNSF—as the carrier—exercises complete control of the trackage

<<<PAGE 2>>>

used during the transloading operation. You ask whether this scenario would meet the
definition of “private track” in § 171.8.
A2. Based on the scenario as described in your letter, the answer is no. As previously stated,
“private track” is defined in § 171.8 as “track located outside of a carrier’s right-of-way,
yard, or terminals where the carrier does not own the rails, ties, roadbed, or right-of-
way.” Therefore, based on the scenario described in your letter, it is the opinion of this
Office that the scenario at the East Pine location does not meet the definition of “private
track” in § 171.8.
However, if the trackage where the transloading occurs were owned by USRL or were
leased to USRL by BNSF with exclusive use by the lessee (i.e. USRL), for the purpose of
moving only rail cars shipped to or by the lessee, and the lessor (i.e., BNSF) exercised no
control over or responsibility for the trackage or cars on the track, this trackage would
meet the definition of “private track” in § 171.8. Lastly, PHMSA views the 745-ft. stretch
of track (owned by USRL) as “private track” based on the information you shared
regarding lease of that track by the owner.
I hope this information helpful. Please contact us if we can be of further assistance.

Subject: Tulsa butane hazards
Dear Mr. Davis,
Thank you for responding to my November 12, 2023, letter to Secretary Buttigieg.
This letter addresses the two butane transloading operations in the city of Tulsa. I plan to
address the consequential butane safety issues in a future letter.
Although this has been discussed as a railroad preemption issue, you have explained PHMSA
lacks jurisdiction if the operations are conducted on “private track” and “PHMSA needs more
information to determine whether the Tulsa area transloading sites meet the definition of
private track”.
I enclosed with my letter to Secretary Buttigieg a redacted letter which provided “private track”
information. I am now able to provide a complete copy of the letter addressed to “Concerned
Citizens” from Mr. Peter A. Pfohl, Slover & Loftus LLP .
“Concerned Citizens” is a group of seven Tulsans that retained Mr. Pfohl to address this
important public safety issue.
I respectfully request that PHMSA provide a statement that the butane transloading operations
are “private track”.
Please advise me if additional information is required.
Sincerely,

Mr. Fred Storer

Dear Mr. Storer:
Thank you for your letter to Secretary of Transportation Pete Buttigieg and the United States
Department of Transportation (Department), regarding butane railcar storage and transloading
activities being performed at two sites in the vicinity of Tulsa, Oklahoma (City). The Pipeline
and Hazardous Materials Safety Administration (PHMSA) is the Agency within the
Department responsible for administering federal pipeline and hazardous materials laws and
regulations, and the Secretary has asked me to respond on his behalf.
In your letter, you highlighted several issues identified by a group of concerned citizens related
to the transportation of energy and other hazardous materials and ask for the Department's
guidance on pipeline safety law and whether federal law preempts the City's local zoning
laws. You also provided a memorandum regarding Surface Transportation Board preemption.
Your letter also noted that Tulsa officials are not enforcing the City's local zoning laws against
the operators of the transloading sites because they believe the City's laws are preempted by
the Surface Transportation Board under the ICC Termination Act of 1995. In addition, you
indicated local government needs to understand whether railcar parking and transloading of
hazardous materials preempts local codes. Finally, you have expressed safety concerns
regarding encroachment at the right-of-way for Explorer Pipeline in Oklahoma, as well as
concerns about the lack of public awareness.
Regarding federal preemption, the Department has preemption authority under the Federal
Hazardous Materials Transportation Law, in addition to the preemption authority of the
Surface Transportation Board.
PHMSA also has delegated authority to make a preemption determination as to whether a nonfederal
requirement is preempted under the Federal Hazardous Material Transportation Law
(HMTA), 49 U.S.C. 5101 et seq. HMTA and its implementing regulations-the Hazardous
Materials Regulations (HMR)-apply to persons who transport or cause hazardous materials
to be transported in commerce and to pre-transportation and transportation functions.
Transloading operations and storage incidental to movement generally are regulated
transportation functions, but there are some exceptions. For example, pursuant to 49 C.F.R. §

<<<PAGE 10>>>

Sit sw Region Community Liaisons have worked with you to
address your safety concerns, including your concerns about butane injections and Explorer's
public awareness in Tulsa. Also, on June 13, 2022, the Vice President of Health, Safety,
Security and Environment and the Public Awareness Administrator at Explorer Pipeline met
with you in Tulsa to discuss these items. Finally, PHMSA's Central Region Director has been
communicating with you since January 2023 in an effort to address your concerns.
We appreciate and value your commitment to pipeline safety. PHMSA will be follow up with
Explorer Pipeline again on these matters to ensure compliance. If PHMSA finds any issue of
noncompliance with the federal pipeline safety regulations, or other potential safety or
integrity issues, PHMSA may exercise its enforcement authority to require the company to
take appropriate corrective measures.
In addition, thank you for your suggestion to reflect differences between types of hazardous
liquids in the pipeline safety regulations. Presently, the regulations at 49 C.F.R. part 195 apply
to pipelines transporting petroleum, petroleum products, anhydrous ammonia, ethanol and
other non-petroleum fuels (including biofuel), and supercritical carbon dioxide. In general, the
regulations apply equally to the transportation of all these materials, but there are a few
differentiations. For example, the regulations include specific requirements for pipelines
PHMSA will consider your suggestion to explicity identify dient in the etmosphere

1 The HMR defines private track as (i) Track located outside of a carrier's right-of-way, yard, or terminals where
the carrier does not own the rails, ties, roadbed, or right-of-way, or (ii) Track leased by a railroad to a lessee,
where the lease provides for, and actual practice entails, exclusive use of that trackage by the lessee and/or a
general system railroad for purpose of moving only cars shipped to or by the lessee, and where the lessor
otherwise exercises no control over or responsibility for the trackage or the cars on the trackage. See 49 C.F.R. §

The Honorable Pete Buttigieg
Secretary of Transportation

Washington DC 20590
Tulsa’s butane risks
Dear Secretary Buttigieg,
In 2015 a butane transloading operation began at a rail spur in the historic Greenville
neighborhood within sight of Tulsa’s city hall. Semis then moved the butane 14 miles across
metro Tulsa to a terminal located at Explorer Pipeline’s Glenpool, Oklahoma, tank farm where it
was and is blended into a flowing stream of diluent destined for the Canadian tar sands.
This butane business which benefits the four owners of Explorer Pipeline and is essential for the
export of Canadian tar involves risks which are regulated by DOT including preemption of
federal railroad rules and hazardous pipeline regulations. This letter will summarize the history
and issues for the benefit of the DOT and request DOT’s assistance in mitigating the risks.
2015 to October 2017
Although EPA Risk Management Plans including Offsite Consequence Analysis (40 CFR 68) were
filed by the initial operator, the transloading operation was not recognized by the city of Tulsa. It
was and is in clear violation of the city’s zoning code.
October 2017
The city was considering using a city owned brownfield site contiguous with the rail spur for a
BMX cycle sport venue which was expected to attract families from across the country. The
conflict between the potential hazard and exposure of BMX participants was recognized by the
city.
January 2018
Local media reported on the hazard and the dialogue between the transloading operator and
the city. Without resolving the conflict, the city built and opened the BMX venue, therefore,
accepting exposure to the risks described in the facility’s Risk Management Plan. In accordance
with the RMP rules (40 CFR 68) the Offsite Consequence damage distance was reported as 0.4
miles based on the release of the contents of a single railcar, one of 26.

<<<PAGE 13>>>

January 2022
As the BMX facility was completed and opened, a second transloading facility was opened 3.5
miles to the east, it was also in violation of the city zoning code, a poor neighborhood with 1700
people living in the RMP explosion damage distance.
November 2022
Although general opposition to butane transloading was expressed by the city council, the city
attorney believed the city’s rules were preempted by federal railroad law. Lay people attempting
to understand railroad law and regulations discovered the city’s rules may not be preempted.
An expert opinion was needed. Seven prominent citizens funded an opinion by railroad law
expert. The expert’s opinion confirmed the city’s rules are not preempted and the city attorney
subsequently agreed with the expert. The city is reported to have retained the expert, but the
city has still not acted to enforce its zoning and fire codes. (A paper copy of the expert’s opinion
was attached to Secretary Buttigieg’s copy. The expert’s name and his qualifications are
redacted at the request of the group that paid for the opinion. However, I am advised the city
attorney has the complete document. Google is blocking electronic copies, please contact Fred
Storer for a copy.)
Local rules are all there is when it comes to the location of parking of and transloading from
hazardous railcars. The assistance of DOT is necessary to clarify the rules to make determination
of federal preemption straight forward.
Fate of Butane
Three to four semi loads are required to empty a butane railcar. The trip to Glenpool is not
without risk, a loaded semi turned over when making a left turn across the north bound lane of
U.S. 75 on March 14, 2023. All butane semis must make this turn.
At Glenpool the butane is unloaded to active storage and then injected into a passing diluent
stream in route to Canada. The technology used for butane injection accurately raises the vapor
pressure to 15 psi, about twice the vapor pressure of gasoline. Of the transportation fuels
Explorer was built to move, motor fuel gasoline was the highest vapor pressure product
transported.
From: Explorer Pipeline Safety Data Sheets
Gasoline SDS # EXPL-2 Diluent SDS # EXPL-15
Vapor Pressure at 25 deg C 400 mm Hg 510-760 mm Hg

<<<PAGE 14>>>

Flash Point -40 deg F -70 deg F
Boiling Point (760 mm Hg) 104 deg F 84 deg F
A leak of 15 psi diluent would flash butane significantly extending the ignition envelope over
gasoline.
Explorer’s Incident Experience
March 9, 2000, Explorer lost 564,000 gallons of gasoline [47,000 gas station fill-ups] about 45
miles northeast of Dallas near Greenville, Texas. A smart pig had been run in 1997 and the
pipeline passed that inspection. The NTSB concluded (Pipeline Accident Number: DCA-00-MP-
005) “... the probable cause of the pipeline failure was corrosion-fatigue cracking that initiated
at the edge of the longitudinal seam weld at a likely pre-existing weld defect. Contributing to
the failure was the loss of pipe coating integrity.”
The Greenville failure, Explorer’s largest to date, was in a rural area and did not find an ignition
source. A 15-psi diluent release of that magnitude in Tulsa would have been much more likely to
result in disastrous consequences.
Explorer’s Incidents from 1986 to 10/29/2023 as reported to PHMSA.
Incident Cause Type All Reports Significant Serious
All Other 15 9 0
Corrosion 19 9 0
Excavation Damage 12 10 0
Incorrect Operation 47 7 0
Material/Weld/Equip Failure 106 26 0
Natural Force Damage 7 2 0
Other Outside Force Damage 1 0 0
Total Reported 207 63 0
Greenville was reported as Significant but not Serious. Significant reports average 1.7 per year
on Explorer’s system.
Right-of-way encroachment
Explorer’s rights-of-way were obtained by negotiation and condemnation across open land
south of Tulsa and north of Broken Arrow, Oklahoma. The easements give Explorer adequate
authority to prevent encroachment. However, shortly after the pipeline became operational in
1972 subdivision surveys began and plats were filed with local governments that encouraged
encroachment.

<<<PAGE 15>>>

Examples extracted from typical plats are shown here:
Sun Medow II
Sun Medow III

<<<PAGE 16>>>

The pipeline easements are at the back of the lots and centered on the pipeline. Lot lines then
result in cross fencing. Time passes and the pipeline is forgotten, encroachment is common, and
an emergency response would be compromised. Stake holders lack knowledge and
encroachment, particularly privacy fences, can hide inappropriate activities including sabotage.
Today, Explorer’s website reflects right-of-way (ROW) best practices
(https://www.expl.com/report-right-of-way-encroachment/ ).
“Unauthorized building or planting in the pipeline right-of-way is known as
encroachment. Explorer regularly conducts maintenance to trim trees and remove shrubs
or structures that are on the right-of-way. We need to be able to clearly view the pipeline
corridor during aerial or foot patrols as part of our safety practices. If you see trees,
plants or structures including sheds located near the pipeline, email us
at row@expl.com.”
In Tulsa County Explorer does not conduct maintenance to trim trees and remove shrubs or
structures.
Explorer’s website regarding cross fencing (Microsoft Word - EPL-331 Encroachment
Specification Revised (002).docx (expl.com) :
“8. FENCES – BARRIERS – WALLS
A) Privacy fences are not permitted, unless otherwise authorized by the easement or as
approved by Explorer Pipeline’s Public Awareness Program Administrator.
B) Fence posts shall not be installed within 3 feet of the center of the pipeline and the
first post either side of the pipe shall be set in hand dug holes. To perform normal
maintenance, access through or around fences crossing the right-of-way must be
provided.”
In Tulsa County Explorer does not attempt to correct past sins regarding privacy fences or
regulate the placement of fence posts. The forgotten about pipeline is vulnerable to past and
future damage.
Encroachment in unplated areas
One of the most dramatic errors is the schoolyard of Southeast Jenks Elementary School where
the pipeline passes through the school yard for over 700 feet as shown here:

<<<PAGE 17>>>

Schools are included as a “Stakeholder
Audience” in API RP 1162 which should
include parents of SE Jenks Elementary
students.
SE Jenks Elementary was built in 1990.
API Recommended Practice (RP) 1162
49 CFR 195.440, Public Awareness
(a) Each pipeline operator must develop and implement a written continuing public
education program that follows the guidance provided in the American Petroleum
Institute’s (API) Recommended Practice (RP) 1162 (incorporated by reference, see
part 195.3).
Explorer’s response to RP 1162 in the form of a mailout to the affected public includes “Signs of
a leak”, “What to do if a leak occurs”, and “How to recognize a leak”.
Required by RP 1162 (5.3.5) but not included in Explorer’s mail out is encroachment, privacy
fences, landscaping, storage buildings, access to the pipeline system during emergencies, and
the importance of the ROW area being clear of trees, shrubs, buildings, fences, structures, or
any other encroachments that could affect the integrity of the pipeline. Explorer’s mailer does
not direct the public to the ROW hazards described on their website.
RP 1162, New Hazards (6.3) includes “Certain operational changes initiated by the operator can
introduce new hazards that have not been previously communicated to affected stakeholders.”

<<<PAGE 18>>>

The all-encompassing term “Petroleum” used in Part 195 and in Explorer’s public
communications and shown on their pipeline markers is not at all adequate to explain the
different commodity groups that have different leak recognition and response requirements.
Help needed.
• Local government needs the ability to determine if railcar parking and transloading of
hazardous materials preempts local codes.
• Explorer Pipeline should be required to discontinue or fully justify the risk associated
with transporting 15 psi diluent across Tulsa in their 50-year-old pipeline.
• Explorer Pipeline should be required to present a plan for correcting historic
encroachment.
• Explorer Pipeline should be required to fully comply with the requirements of API RP
1160 and 1162.
• 49 CFR 195 should be changed to reflect the differences between relatively low hazard
materials such as diesel and jet fuel and motor gasoline and 15 psi diluent.

MEMORANDUM
To: Tulsa Concerned Citizens
From: Re: Peter A. Pfohl, Slover & Loftus LLP
Federal Preemption of Local Zoning, Permitting, and Safety Laws
Governing Butane Transloading in Tulsa
Date: March 1, 2023
I.
EXECUTIVE SUMMARY
We have been asked to present the framework, reach, and application of federal
preemption of local laws under the ICC Termination Act of 1995, Pub. L. 104-88, 109
Stat. 803 (“ICCTA”) as they apply to the storage and transloading of large volumes of
butane, a hazardous commodity, being performed at two sites in in Tulsa, Oklahoma, at
or near: (1) 660 East Independence Street, an area near downtown close to BMX USA
(“Downtown Site”) and (2) 5307 East Pine Street, located in Northeast Tulsa (“East Pine
Site”), collectively the “Sites”.
The owners/lessees of these Sites have engaged in the unpermitted storage and
transloading of many millions of pounds of butane annually, a highly flammable
hazardous chemical, and these activities appear to have been increasing recently. In the
event of accidental discharge, such activities pose serious, and imminent public health
and safety threats to the substantial nearby populations, neighborhoods, and the
environment. These are activities that implicate multiple zoning, permitting, fire code,
and other public safety ordinances, codes, and laws. Most notably, both Sites are zoned
only for light or medium industry, which prohibits the storage and transloading of such
hazardous materials. Also, neither Site has received permission to operate through any
permit, Variance, or Special Exemption use to our knowledge.
While the open zoning violations at the Sites are subject to enforcement actions,
injunctive relief, and substantial penalties, of $1,200.00 or more per day for each
violation under City Zoning Laws, to date, no such enforcement actions have taken place
to our knowledge. Instead, it appears that local enforcement officials may have assumed
that, because the activities involve railroads acting within the jurisdiction of the federal
Surface Transportation Board (“STB” or “Board”) under ICCTA, all zoning, permitting,
fire code, and other public safety laws are completely preempted by federal law.
However, based on the facts known to date, and for the reasons discussed below,
we do not believe the butane railcar storage and transloading activities being conducted at

the Sites are within the jurisdiction of the STB and eligible for preemption protection
under ICCTA. In sum, based on the facts known to date, we know of no federal law that
would prevent local officials from enforcing applicable ordinances, codes, laws, and rules
immediately. We are also unaware of any applicable legal authority that would
reasonably support a finding of preemption, and believe that any asserted defense of
preemption by the operators of the Sites in response to such enforcement actions would
be unsuccessful.

QUALIFICATIONS
I am an attorney with twenty-five years’ experience in rail transportation law, and
our firm has been participating in the space for over 50 years. I have represented a wide-
variety of stakeholders in the transportation arena, including railroad shippers and
receivers, states, cities, localities, public agencies, ports, terminals, and short-line
railroads, on a broad range of issues. In the course of these representations, I have
worked on numerous matters involving the common carrier obligation, agency
jurisdiction, and federal preemption. In my practice, I have addressed many of the issues
that commonly arise with respect to ICCTA preemption, including, but not limited to
issues relating to: (a) the STB’s jurisdiction over transportation, property, and track, (b)
categorical (or express) preemption; (c) as-applied preemption; (d) preemption of local
ordinances; (e) preemption of state environmental and safety statutes; (f) preemption of
other state or federal law remedies; (g) preemption of state property rights claims; (h)
preemption of state contract law claims; (i) preemption of state tort claims; and (j) the
authority of courts and the STB to decide jurisdictional and preemption matters.
My practice has included representation of clients on these matters in various
disputes before state and federal courts and arbitral panels, and in proceedings and
hearings before the STB, the Federal Railroad Administration (“FRA”), and the Pipeline
and Hazardous Materials Safety Administration.
I earned a Bachelor of Arts degree from the University of Notre Dame (1989) and
earned my Juris Doctorate degree from the Columbus School of Law at Catholic
University of America (cum laude) (1997). I am an active member of the bar for the
District of Columbia, and am a past President, and current Board Member, ex officio, of
the Association of Transportation Law Professionals. I have received several
professional honors for my practice, including Band 1 ranking by Chambers USA,
“Leaders in their Field,” for Transportation: Rail (for shippers) (Nationwide), and was
recently named “Lawyer of the Year” by Best Lawyers for Transportation Law,
Washington D.C., 2023.

FACTUAL BACKGROUND
The involved butane railcar storage and transloading activities are being conducted
at two locations, the Downtown Site and the East Pine Site.
A. Downtown Site Butane Railcar Storage and Transloading Activities
The Downtown Site is in Tulsa’s Historic Greenwood District, a Oklahoma Main
Street Community and Destination District. The location consists of a an approximately
8.4 acre privately leased site immediately adjacent to yard track owned by Watco, a non-
carrier transportation services and shortline holding company, and/or its subsidiary South
Kansas & Oklahoma Railroad (“SKOL”) (collectively “Watco/SKOL”). SKOL is a
Class III, shortline railroad that operates over 425 miles of track and interchanges/
connects with other railroads (e.g., BNSF, UP, and KCS) at several nearby locations.
The Downtown Site is immediately adjacent and to the West of the 12.6 acre site
of USA BMX headquarters and Hall of Fame opened in 2022, and to the East of
Oklahoma State University-Tulsa. It is also immediately adjacent and to the West of the
9.5-acre site owned by the City of Tulsa which has recently approved the $44 million
redevelopment of the 120,000-square-foot Oklahoma Ironworks building into a mixed-
use food, retail, office/business incubator space. See https://www.cityoftulsa.org/press-
room/team-alchemy-selected-to-redevelop-historic-evans-fintube-site/. The location of
the Downtown Site is depicted in the schematic below.

<<<PAGE 23>>>

The Downtown Site includes two spur tracks extending 1,865 feet, with 26 railcar
capacity. Watco/SKOL designed and constructed the Downtown Site in 2015 as a
liquified petroleum gas storage and transloading site to be leased to third parties. Since
construction completion, we understand that two tenants have leased, occupied, and
operated butane railcar storage and transloading at the Site, including Base, Inc. (d/b/a
Second Base), and most recently, Centennial Energy, LLC a subsidiary of NGL Energy
Partners LP (“Centennial/NGL Energy”).

A recent inspection report of the Downtown Site by the Environmental Protection
Agency’s (“EPA’s”) Enforcement and Compliance Assurance Division (“EPA Inspection
Report”) described in detail operations at the Site. A copy of the EPA Inspection Report
is set forth at Attachment 1. The butane is owned by Keyera Energy, LLC (“Keyera),
and is shipped by rail in railroad line-haul service to Centennial/NGL Energy’s leased
Downtown Site in approximately 30,000-gallon (~146,000 pound) railcars, delivered by
SKOL. The product is temporary stored in place in the railcars at the Downtown Site by
Centennial/NGL Energy, and ultimately transloaded to approximately 9,200-gallon
tanker trucks by RLS International Transport Services, Inc. (“RLS”), Centennial/NGL
Energy’s contractor. The product is then transported by truck (3-4 trucks per railcar) by
Groendyke Transport, Inc. (“Groendyke Transport”), back through the City of Tulsa
some 16 miles south of the City to Keyera’s Oklahoma Liquids Terminal, in Glenpool,
Oklahoma, acquired by Keyera in 2018.
The Keyera Terminal is situated on the southwest corner of the Glenpool tank
farm, owned and operated by Explorer Pipeline Company. We understand that Keyera
receives and stores the butane at its Terminal, where it is then blended at the location, and
transported via Explorer’s pipeline and connecting pipelines to Canada to make
pumpable bitumen.
The EPA Inspection Report found several safety violations of EPA rules,
including inadequate hazard assessment techniques by the operator to identify butane
leaks from railcars and a failure to submit a Risk Management Plan (“RMP”). A RMP
identifies the potential effects of a chemical accident and an evaluation of worst-case and
alternative accidental releases. A RMP also provides a history of accidents/releases,
accident prevention programs, and emergency response procedures to be taken should an
accident occur.
We understand that a RMP submitted by the previous tenant of the Downtown Site
identified the Offsite Consequence Analysis (“OCA”) “worst case” damage distance of
an accidental butane release from a railcar of 0.4 miles, covering a significant area of
Downtown Tulsa. Broadly, for butane, a flammable gas, this is the distance a vapor
cloud explosion blast waves will travel before dissipating to the point that serious injuries
from exposure will no longer occur. 40 C.F.R. part 68. Put differently, this is the
distance required for the pressure wave created by the exploding contents of a single
railcar, one of 26, to dissipate to the point where injury or structural damages do not
occur. However the larger concern of many citizens is the consequence of a fire
occurring at one of three locations where a trailer mounted apparatus is used to make
temporary connections via flexible hoses between a rail car and a semi-truck trailer. A
fire which impinges on a railcar or trailer can create the conditions for a Boiling Liquid
Expanding Vapor Explosion (“BLEVE”). A BLEVE could launch fragments of the
vessels for hundreds of yards, causing catastrophic injuries and harm to the public.
Should the threat of BLEVE incident arise, the Fire Department would need to evacuate

the area, including closing U.S. 75 and I-244, for an extended period while the fire
burned out and cooled down, which is what recently occurred with the rail derailment in
East Palestine, Ohio, which led to the evacuation of the town, and the controlled release
and burning of hazardous commodities from railcars.
It is unclear the total volume of butane currently being stored/transloaded at the
Downtown Site by Centennial/NGL Energy, but the maximum volumes appear consistent
with the previous operator at the location, who reported to EPA that it temporarily stored
in place in railcars as much as 3.8 million pounds (or approximately 781,000 gallons) of
butane at one time in batches of 26 railcars. Watco has recently listed the Downtown Site
as available for lease for LPG transloading by third parties. A copy of Watco’s leasing
brochure is set forth at Attachment 2.
B. East Pine Site Butane Railcar Storage and Transloading Activities
The East Pine Site is located in Northeast Tulsa and is adjacent to the Maplewood
and Dawson residential neighborhoods, and the Mike Patrick Park. The Site is owned by
Base, Inc., however, a substantial portion of railroad track on and near the parcel,
including the mainline used to serve the facility comprising part of BNSF’s Cherokee
Subdivision, is owned by BNSF Railway, Inc., a Class I common carrier railroad.
The location and relevant aspects of the Site, including rail lines, and the butane
railcar storage and transloading locations, are shown in the schematic below.

<<<PAGE 26>>>

As reflected above, a very small portion of the railroad track (highlighted in
yellow), consisting of 745 feet of track, was authorized by the STB in 2021 to be leased
(along with accompanying undeveloped land) to a newly created subsidiary of Base, Inc.,
Tulsa Base Railroad, L.L.C. (“TBR”) for common carrier service in FD 36536, Tulsa
Base Railroad, L.L.C. – Lease & Operation Exemption – Base Inc. The remainder of the
track where railcars are stored and transloaded is classified as private industry track,
owned and maintained by Base, Inc. as reflected in the drawings provided by TBR to the
STB in FD 36536, shown below:
We understand, but have not been able to confirm to date, that the butane being
shipped to the East Pine Site for storage and transloading, like at the Downtown Site, is
owned by Keyera. It is shipped by rail by to the Site by BNSF, also in approximately
30,000-g
