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.

Steven Andrews

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.

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

<<<PAGE 21>>>

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,

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.
- 3 -

<<<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”).
- 4 -

<<<PAGE 24>>>

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
- 5 -

<<<PAGE 25>>>

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.
- 6 -

<<<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-gallon (~150,000 pound) railcars. Similar to the operations being performed by
Centennial/NGL Energy at the Downtown Site, after temporary storage on-site, the
railcars are ultimately transloaded to approximately 9,200-gallon tanker trucks on the
Base’s private industry track to the East of the Sweetener Facility. The product is then
transloaded and transported by truck by Groendyke Transport, apparently to Keyera’s
Oklahoma Liquids Terminal.
TBR may obtain a switching fee for railcars delivered by BNSF to the 745 feet of
common carrier track that it operates. However, it is unclear if TBR is an active common
carrier railroad, as it does not appear that TRB has filed any accident/incident reports
- 7 -

<<<PAGE 27>>>

with the FRA required of all active common carrier railroads, nor does it appear that TRB
has registered to date as a covered employer with the Railroad Retirement Board as
required under the Railroad Retirement Act (45 U.S.C. § 231 et seq. (“RRA”) and the
Railroad Unemployment Insurance Act (45 U.S.C. § 351 et seq.) (“RUIA”).
The volume of butane being stored at the East Pine Site reported to the EPA in a
recent RMP is as much as 7.8 million pounds (or 1.6 million gallons) at one time
(roughly 53 railcars). We understand transloading occurs continuously in daylight hours
six days a week. We also understand that the OCA “worst case” damage distance of an
accidental butane release of a single railcar to be 0.4 miles, covering a population of
approximately 1,400 people, along with schools, public recreation (including the Mike
Patrick Park), and churches. Also, just like the Downtown Site, the larger concern of
many citizens is a fire originating at one of three connections between railcars and semi-
trailers which could result in a BLEVE.
III.
GENERAL STATUTORY OVERVIEW
Through ICCTA, Congress has provided the STB broad regulatory authority over
common carrier freight railroads and the transportation they provide as part of the
interstate rail network. 49 U.S.C. § 10501. The STB has exclusive jurisdiction over rail
transportation by rail carriers and “the construction, acquisition, operation, abandonment,
or discontinuance” of rail lines pursuant to 49 U.S.C. § 10501(b). Under 49 U.S.C. §
10102(5), a “rail carrier” is defined as “a person providing common carrier railroad
transportation.” Among other things, common carrier lines are subject to STB licensing
and abandonment requirements; common carriers are obligated to provide service to
those located on their lines upon reasonable request; and the STB has exclusive
jurisdiction over common carrier rail transportation service, and the construction,
acquisition, operation, and abandonment of common carrier railroads and railroad lines.
49 U.S.C. § 10502.
State and local laws that affect common carrier operations are subject to federal
preemption. This could potentially include local zoning and permitting laws that by their
nature could be used to deny a railroad the right to conduct rail operations or proceed
with transportation activities the Board has authorized, as well as attempts to address
transportation matters that are exclusively regulated by the Board such as railroad rates or
common carrier operations. While the preemption of state and local laws affecting
legitimate railroad activities is intentionally broad, the states do retain certain historic
police powers designed to protect the safety and health of the local population (e.g.,
plumbing codes, fire codes).
- 8 -

<<<PAGE 28>>>

There is a two-part test for preemption to apply to storage and transloading
activities, generally summarized: (1) construction/operation activities must comprise
transportation, and (2) the activities need to be conducted by or on behalf of a rail carrier.
Transloading activities when sufficiently connected with common carrier railroad service
are indeed “transportation,” but as to the activities, they must be performed by, or under
the auspices of a “rail carrier.” E.g., Fla. E. Coast Ry. v. City of Palm Beach, 110 F.
Supp. 2d 1367 (S.D. Fla. 2000), aff’d, 266 F.3d 1324 (11th Cir. 2001) (third-party
noncarrier rail/truck transloading activities are not exempt from local zoning and
occupational licensing ordinances). Where an activity, even where on railroad property is
not considered transportation by a rail carrier, no federal preemption applies, and states
and localities may fully regulate the activity.
Whether a particular activity is considered part of transportation by rail carrier
under § 10501 is a case-by-case, fact-specific determination. Franks Inv. Co. LLC v.
Union Pac. R.R. Co., 593 F.3d 404, 413-16 (5th Cir. 2010) (en banc).
IV.
ANALYSIS
Based on the facts known to date, we do not believe that the butane railcar storage
and transloading activities being conducted at either the Downtown Site or the East Pine
Site are a part of rail transportation under the exclusive jurisdiction of the STB that
qualify for preemption.
A. Preemption Does Not Likely Apply to Local Zoning, Permitting, and
Other Safety Laws Governing the Downtown Site
In order for an activity to be subject to the STB’s jurisdiction, and therefore
entitled to preemption, an activity must constitute both transportation and must be
performed by, or under the auspices of a “rail carrier” as defined under 49 U.S.C. §
10501(a). Hi Tech Trans, LLC v. New Jersey, 382 F.3d 295, 307-10 (3d Cir. 2004); New
York & Atlantic Ry. Co. v. STB, 635 F.3d 66, 72-75 (2nd Cir. 2011).
At the Downtown Site, Watco/SKOL is leasing the Site to a third party,
Centennial/NGL Energy. Centennial/NGL Energy is conducting the transloading
services at the site, through its contractor RLS, and neither are a common carrier railroad.
The only such railroad near the Site is SKOL, but again it is not storing or
transloading the butane cars. Instead, the property is possessed and controlled by a third
party lessee, Centennial/NGL Energy, who is independently conducting the butane
storage and transloading activities at the Site. SKOL’s common carrier transportation
duties, including its responsibility and liability for the railcars, ends when they are
delivered and uncoupled at the Downtown Site. The railcars are then stored and
- 9 -

<<<PAGE 29>>>

transloaded by Centennial/NGL Energy or its subcontractor. SKOL is not holding out its
own transloading service through a third-party as an agent, nor is it exerting control over
the Centennial/NGL Energy’s operations.
The services cannot meet the second part of the ICCTA preemption test, as they
are not being conducted by a STB certified common carrier rail carrier or under the
auspices of such a common carrier as part of its rail transportation services. As such,
local regulation of the storage and transloading activities is not preempted. E.g., Town of
Babylon and Pinelawn Cemetery – Petition for Declaratory Order, FD 35057 (STB
served Oct. 16, 2009) at 4 (transloading activities did not qualify for preemption because
the activities of the operator were not under the control of the New York and Atlantic
Railway Company, the carrier on whose property the facility was located); Town of
Milford, MA – Petition for Declaratory Order, FD 34444 (STB served Aug. 12, 2004)
(no STB jurisdiction over a noncarrier operating a transloading facility within a rail yard
pursuant to an agreement with rail carrier for non-exclusive use of the yard); accord Hi
Tech Trans, LLC; New York & Atlantic Ry. Co.
Also, the involved tracks appear to be of the nature of private track, constructed by
Watco/SKOL to be leased for the exclusive use by third-party, non-carrier tenants. In
such instances, even operations by a common carrier over such track do not subject the
operations to the STB’s jurisdiction. For example, “where a carrier serves a mine over
private track owned and maintained by the shipper, and does not serve others over that
track, the carrier operation is [not subject to STB regulation].” New York Cent. R.R. v. S.
Ry. Co., 226 F. Supp. 463, 471 (N.D. Ill. 1964). Again, SKOL is delivering the butane
railcars to the Downtown Site, and upon delivery, its common carrier service obligations
(and duties) cease. The railcar storage and transloading activities that occur following
delivery by SKOL are not part and parcel of any common carrier rail transportation.
See North Am. Freight Car. Ass’n v. BNSF Ry., NOR 42060 (Sub-No. 1) (STB served
Jan. 26, 2007) at 15 (storage of private railcars on private track by a non-carrier is not
within the STB’s jurisdiction).
Additionally, even if the track were considered to be so-called “spur” track subject
to the jurisdiction of the STB under 49 U.S.C. § 10906, again, the involved common
carrier serving the location, SKOL, is not performing the physical transloading, and is not
holding out transloading as part of its service. SKOL also is not compensating the third-
party transloader or controlling the transloading activities.
Accordingly, at a minimum, Centennial/NGL Energy cannot satisfy, this
mandatory “rail carrier” element for § 10501(b) preemption. Where a non-railroad is
operating a transload facility separately for its own benefit, it is not subject to the
jurisdiction of the STB and there is no preemption.
- 10 -

<<<PAGE 30>>>

B. Preemption Does Not Likely Apply to Local Zoning, Permitting, and
Other Safety Laws Governing the East Pine Site
Similarly, for the East Pine Site, the involved tracks where transloading occurs
appear to be private industry track, owned or possibly leased (from BNSF) by Base, Inc.
At the Site, the butane railcar storage and transloading operations appear to be conducted
by Base, Inc. on private, industry track. BNSF delivers the cars to East Pine Street,
where its common carrier responsibility and responsibility for the cars ends. The cars are
then privately switched to the private industry tracks for storage and transloading from
railcar to truck by Groendyke Transport. Under the authorities cited in the previous
section, none of these activities are entitled to preemption protection under ICCTA.
It is true that Base, Inc. established Tulsa Base Railroad, L.L.C., ("TBR"), which
obtained authority from the STB in 2021 to conduct common carrier operations on 745
feet of single-line track that it subleases from Base, Inc. at the location to the northeast of
the so-called “sweetener facility.” However, no transloading activities are being
conducted on that limited 745 feet of common carrier track where TBR is authorized to
operate as a common carrier.
Also, the facts known to date appear to show that TBR is not actively conducting
operations at the East Pine Site as a common carrier. STB decisions (including
exemptions) authorizing railroad common carrier operations are permissive only, and the
authority granted must then be properly effectuated by the entity seeking common carrier
certification. E.g., Oakland Global Rail Enterprise, LLC – Operation Exemption – Rail
Line of Union Pac. Railroad Co. and BNSF Railway Co., FD 35822 (STB served July 24,
2014), at 1. TBR does not appear to have any registered railroad employees under the
RRA and the RUIA, and as such, does not appear to be operating as an active common
carrier, even though it might still be obtaining “switch” fees from BNSF for the
interchange/receipt of each railcar on its 745 feet of common carrier track. The railroad
retirement laws generally apply only to STB-regulated carriers and their activities. They
do not apply to “private” railroads or private switching activities, which are not subject to
STB jurisdiction. TBR also does not appear to have engaged in any FRA monthly
reporting required of common carriers that might help show that it is an active common
carrier. See e.g., 49 C.F.R. Part 225, FRA Form 6180.55.
Additionally, even assuming arguendo that TBR is an active common carrier,
TBR has never sought STB authority to conduct common carrier services on the
transloading track. And if TBR is performing railcar switching activities on the private
industry track where transloading occurs, as referenced above, that does not convert those
operations to common carrier operations. New York Cent. R.R., 226 F. Supp. at 471;
accord B. Willis, C.P.A. Inc. – Petition for Declaratory Order, FD 34013 (STB served
Oct. 3, 2001), at 3 (the court in “New York Central” [ ] “indicated that a common carrier
operating over private track would not [be engaged in regulated operations], so long as it
- 11 -

<<<PAGE 31>>>

does not perform common carriage service on the private track and it does not maintain
that track with its own funds.”); Florida E. Coast Ry. v. City of W. Palm Beach, 266 F.3d
1324 (11th Cir. 2001) (transloading of cement within rail yard not within Board
jurisdiction).
Further, the transloading tracks are not directly connected to TBR’s 745 feet of
common carrier track leased from BNSF, and possibly subject to the STB’s jurisdiction
as exempt “spur” tracks.1 Instead, the tracks have been designated by TBR and Base,
Inc. in STB filings as private industry track, and, as such, the entity conducting service
over the tracks is not holding itself out to openly provide service to anyone else. The
STB does not have jurisdiction over these private lines, they are not subject to federal
regulation under ICCTA, or ICCTA preemption, and state and local regulation is fully
applicable to the lines. See, e.g., Suffolk & Southern R.R. – Lease & Operation
Exemption – Sills Rd. Realty, LLC, FD 35036 (STB served Nov. 16, 2007), at 1 n.1;
Willis, FD 34013 (STB served Oct. 3, 2001), at 2; see North Am. Freight Car. Ass’n v.
BNSF Ry., NOR 42060 (Sub-No. 1) (STB served Jan. 26, 2007) at 15 (storage of private
railcars on private track by a non-carrier is not within the STB’s jurisdiction).
Finally, even if the transloading tracks were ultimately considered to be under the
jurisdiction of the STB, and are being conducted by a common carrier as part and parcel
of its common carrier operations, which the facts known to date do not show to be the
case, the FRA requires railroads to expedite each shipment of hazardous materials such as
butane and prevents the railcar from being held on any railroad tracks for more than 48
hours. 49 C.F.R. § 174.14(a). As such, even if the storage and transloading operations
were being conducted on common carrier track (or excepted track) by a common carrier
pursuant to the jurisdiction of the STB, then the FRA 48-hour rule would apply, and the
operators would be in substantial continuing violation of this important federal safety
requirement because many of the loaded butane railcars are stored on the tracks for more
than 48 hours.2
1 Preemption principles can apply to tracks subject to 49 U.S.C. § 10901 (“§
10901 track”) or ancillary and excepted tracks pursuant to 49 U.S.C. §10906 (“§ 10906
track”).
2 We understand that based on FRA’s recent review of operations at the East Pine
Site, and the Downtown Site, FRA has determined that its 48-hour rule is inapplicable to
the railcar storage because the activities are not being conducted by a common carrier on
common carrier (or excepted spur) track. We await further clarification from the FRA on
same.

C. The Authorities Cited by the City to Date are Inapposite,
and the City Has Failed to Consider Directly Applicable Authorities
We are aware that, in response to requests for zoning law enforcement by Tulsa
citizens, the City may have conducted an initial legal review of railroad preemption, and
in doing so, may have assumed, incorrectly, that federal preemption under ICCTA
applies to all, or at least most, railcar storage and transloading activities. The Concerned
Citizens shared one response from the City, which opines as follows:
I am reluctant to get too far into the substantive legal
issues, but the City cannot simply choose to ignore federal
law and authority with respect to rail carrier operations.
In short, the federal Surface Transportation Board (STB) has
exclusive jurisdiction over "transportation by rail carriers" (49
U.S.C. § 10501 (b)(1)), and the Interstate Commerce
Commission Termination Act of 1995 (ICCTA) preempts
state and local laws which come within the jurisdiction of the
STB. Franks Inv. Co. v. Union Pacific, 593 F.3rd 404 (5th
Cir. 2010).
Federal preemption of state and local regulations has
been held to include transloading operations, whether such
activities are performed by a rail carrier, the rail carrier holds
out its own service through a third party that acts as the rail
carrier's agent, or the rail carrier exerts control over a third
party's operations. Borough of Riverdale—Pet. for
Declaratory Order, FD 35299, slip op. at 4 (STB 2010). See,
for example, Padgett v. Surface Transportation Board, 804
F.3d 103 (1st Cir. 2015) (ICCTA preempts state and local
regulation of liquid petroleum gas transloading facility);
Texas Central v. City of Midlothian, 669 F.3d 525 (5th Cir.
2012) (ICCTA preempts city’s regulation of transloading
operations); Norfolk Southern v. City of Alexandria, 608 F.3rd
150, (4th Cir. 2010) (ICCTA preempts city’s regulation of
transloading operations); Green Mountain R.R. Corp. v.
Vermont, 404 F.3rd 638 (2nd Cir. 2005) (ICCTA preempts
state land use law as applied to transloading and storage
facilities).
I am aware of these decisions, and have reviewed them further. I was involved
and assisted in the Franks Investment decision for the plaintiff, which found a general
presumption against preemption and that a landowner’s possessory action seeking the
right to continue to use of private railroad crossings was not preempted. The court found
- 13 -

<<<PAGE 33>>>

that the involved railroad had no right under ICCTA, or under the auspices of
preemption, to override state property laws and unilaterally close private rail crossings in
the absence of a showing of unreasonable interference with rail operations.
The other cases directly address federal preemption of transloading operations, but
are all inapposite. In each case, ICCTA preemption over local laws was found, but only
after a close review of the individual facts and circumstances, which revealed that all the
activities were being conducted by a bona fide common carrier as part and parcel of its
common carrier rail service. For example, City of Alexandria involved a challenge by a
city to ethanol transloading being conducted under the control of the Norfolk Southern
Railway Company (“NS”), where NS fully owned, controlled, and constructed the
facility, the transloading was held out by NS as part of its rail transportation services, and
NS set, invoiced, and collected all transloading fees charged to the shipper as part of its
overall price for its common carrier transportation. While NS hired a contractor to
conduct transloading, the contractor was found not to be conducting transloading services
on its own as an independent business, and only received payment through a flat rate,
without the ability to market the facility in any way. Based on this close review of the
factual circumstances, the involved transloading activities were considered sufficiently
under the control and auspices of NS to make the activities a part of NS’s common carrier
rail transportation services.
The Borough of Riverdale, Padgett, Texas Central, and Green Mountain similarly
examined all the facts and circumstances of the transloading activities being performed,
and only after finding that the transloading activities were being conducted under the full
auspices and control of a bona fide common carrier railroad, did preemption apply. Such
control and authority by a bona fide rail carrier is simply not occurring at either the
Downtown Site or the East Pine Street Site for the reasons cited above. Unfortunately,
the City failed to find or attempt to differentiate any of the many cases cited in the above
sections where the involved transloading activities, similar to the activities occurring at
the Downtown Site and the East Pine Site, were not found to enjoy preemption protection
under ICCTA.
V.
CONCLUSION
Applying the known facts to the applicable law, in our opinion the butane storage
and transloading activities being conducted at the Downtown Site and the East Pine Site
are not part of “transportation by rail carrier” within the STB’s exclusive jurisdiction, and
the operations are therefore not exempt from local zoning, permitting, and other safety
laws.
If the City or County were to enforce applicable ordinances, codes, laws, and
rules, it would be up to each of the entities conducting the storage and transloading
- 14 -

<<<PAGE 34>>>

activities to overcome a presumption against preemption and demonstrate that their
activities are in fact subject to the STB’s exclusive jurisdiction, and therefore eligible for
preemption protection. Based on the facts of record known to us to date, we do not
believe that the operators at the two Sites could successfully overcome this substantial
legal hurdle and establish ICCTA preemption in court or before the STB.
In our opinion, the continuing lack of any enforcement actions in the face of
apparent clear non-compliance with essential land use and public safety laws where the
activities pose a clear threat to public health and safety in sensitive areas of the City
based on the mere possibility of a future defense claim of preemption would constitute a
vastly overbroad reading of applicable ICCTA preemption law and is unjustified.

Section I – INTRODUCTION PURPOSE OF THE INSPECTON
I, the Environmental Protection Agency (EPA) Region 6 inspector Tony Robledo, arrived at the WATCO/SKOL
facility location at approximately 1:30 p.m. on October 12, 2022, and again on the morning of October 13,
2022, for an announced inspection. I met with facility representatives noted above at the opening meeting. I
presented my credentials and informed them that this was an EPA inspection to determine compliance with
CAA § 112(r) and 40 C.F.R. Part 68 Chemical Accident Prevention Provisions. I was informed by facility
representatives that the owner of the property WATCO/SKOL leases the property to Centennial Energy, LLC.
Therefore, Centennial Energy, LLC is the main operator of the site.
FACILITY DESCRIPTION
Facility representatives described the facility’s operations. Operations at this facility location started in
March of the year 2022. Railcars containing liquid butane belonging to Keyera Energy, LLC (Keyera) are
delivered to the facility where Railroad Loading Services, LLC (RLS) conducts transloading and handling
operations. Therefore, RLS is also an operator at the site. Butane arrives at the location in approximately
30,000-gallon (~150,000 pound) railcars and is transloaded to approximately 9,200-gallon tanker trucks
owned by Groendyke. This railcar location can accommodate a total of 26 railcars, with 13 railcars on each
of two railroad tracks, and the butane that is contained in the railcars ultimately offloaded to tanker trucks.
Only butane is transloaded, and no chemical blending is conducted at this location. There were three RLS
non-union employees onsite at the time of the inspection, although I was informed that SKOL and Keyera
may have additional non-union employees onsite periodically, which makes Keyera an additional site
operator. Although Groendyke owns tanker trucks at the site, their employees are not present, therefore
Groendyke is not an operator. Operators at this site work Monday through Friday from 5:00 a.m. to 5:00
p.m.
Section II – OBSERVATIONS
I conducted a walk‐through of the facility, accompanied by facility representatives to observe the facility
process, equipment, and railcar operations. I observed 13 railcars (Photo No. 1) on one railroad track that
were connected to each other with rail car couplings (Photo No. 2). I observed the handling and unloading
of butane from three non-moving/static railcars, which were not connected to a locomotive, onto to three
non-moving/static tanker trucks (Photo No. 3).
During unloading, a mobile generator was used to operate a compressor with a hose connected to the
railcar. Facility representatives explained this procedure was to compress vapor in the railcar to assist in
pushing the butane out of the railcar into the tanker truck (Photo Nos. 4 and 5). Hoses were connected
from the railcar to the tanker truck (Photo No. 6). I observed one small thermal anomaly from a potential
hydrocarbon vapor trail at a tank hatch valve connector on railcar TILX 306572 with the Forward Looking
Infrared (FLIR™) Series GF320 camera (Photo No. 7). The onsite contractors tightened the connector with a
wrench. I considered this action by the onsite contractors an on-the-spot correction. I observed onsite
operators using soapy water solution in spray bottles to check for leaks in accordance with the facility’s
written standard operating procedures, a copy of which facility representatives provided.
Section III – AREAS OF CONCERN
Close-out Meeting – I convened a short closing meeting on Thursday, October 13, 2022. I informed onsite

personnel that a written report would be completed pending the review of additional information requested.
AOC 1. Clean Air Act (CAA) § 112(r)(1) – The General Duty Clause
The owners and operators of stationary sources producing, processing, handling, or storing such
substances [i.e., a chemical in 40 CFR part 68 or any other extremely hazardous substance] have a
general duty [in the same manner and to the same extent as the general duty clause in the Occupational
Safety and Health Act (OSHA)] to identify hazards which may result from (such) releases using
appropriate hazard assessment techniques, to design and maintain a safe facility taking such steps as are
necessary to prevent releases, and to minimize the consequences of accidental releases which do occur.
Based on the observation using the Forward Looking Infrared (FLIR™) Series GF320 camera, and process
knowledge, I determined that the release of the RMP regulated substance was flammable butane. I further
determined that the practice and procedure to identify leaks on railcars using soapy water solution in spray
bottles to be inadequate. EPA notes that there are more advanced and accurate methods for leak
identification that can be used to maintain a safe facility and prevent releases. Such hazard assessment
techniques include the use of hand-held portable instruments with chemical-specific sensors, and hand-held
infrared cameras that use optical gas imaging.
AOC 2. 40.CFR § 68.10 – Applicability
(a) Except as provided in paragraphs (b) through (f) of this section, an owner or operator of a stationary
source that has more than a threshold quantity of a regulated substance in a process, as determined
under § 68.115, shall comply with the requirements of this part no later than the latest of the following
dates: (1) June 21, 1999; (2) Three years after the date on which a regulated substance is first listed
under § 68.130; (3) The date on which a regulated substance is first present above a threshold quantity in
a process; or (4) For any revisions to this part, the effective date of the final rule that revises this part.
EPA requested information regarding the transloading operations to determine the potential regulatory
applicability of 40 C.F.R. Part 68 Chemical Accident Program requirements, specifically regarding the capacity
of butane contained in each railcar, and the length of time that the railcars filled with butane remain
stationary on the railroad track awaiting transloading process operations1
. EPA was provided confidential
business information documents regarding the duration of specific transloading process operations at this
facility location.
AOC 3. 40 CFR § 68.150 – RMP Submission.
(a) The owner or operator shall submit a single RMP that includes the information required by §§ 68.155
through 68.185 for all covered processes. The RMP shall be submitted in the method and format to the
central point specified by EPA as of the date of submission. (b) The owner or operator shall submit the
1 Per § 68.3 Definitions, for the purposes of this part, the term stationary source does not apply to transportation, including
storage incident to transportation, of any regulated substance or any other extremely hazardous substance under the
provisions of this part. A stationary source includes transportation containers used for storage not incident to
transportation and transportation containers connected to equipment at a stationary source for loading or unloading.
Transportation includes, but is not limited to, transportation subject to oversight or regulation under 49 CFR parts 192, 193,
or 195, or a state natural gas or hazardous liquid program for which the state has in effect a certification to DOT under 49
U.S.C. section 60105.

first RMP no later than the latest of the following dates: (1) June 21, 1999; (2) Three years after the date
on which a regulated substance is first listed under § 68.130; or (3) The date on which a regulated
substance is first present above a threshold quantity in a process.
At the time of the inspection, the owner or operator failed to provide documentation that it had submitted
an RMP registration for the transloading operations at this facility, which appear to be subject to the
requirements of 40 C.F.R. Part 68.
