Sentencings
$1.1M Ordered in Restitution for Men Who Fired Shots at Fuel Pipeline Causing Over 3,900
Gallon Spill into Yellow Medicine River in Minnesota
On October 6, 2021, Erik Weckwerth-Pineda and Tanner Sik were each sentenced to one year of probation
and ordered to pay $1,138,772.06 in restitution for causing thousands of gallons of oil to spill into the Yellow
Medicine River.
According to court documents, on April 24, 2019, Eric Jay Weckwerth-Pineda, 25, of Cottonwood, Minnesota,
and Tanner John Sik, 21, of Ivanhoe, Minnesota, traveled to the northwest side of Cottonwood Lake in Lyon
County to a bridge that spans a dam between Cottonwood Lake and a creek called Judicial Ditch 24, which
flows into the Yellow Medicine River. Weckwerth-Pineda and Sik took guns to the bridge to shoot. Sik used a
DPMS AR-15 rifle to fire multiple shots at a diesel fuel pipeline that runs perpendicular across Judicial Ditch
24. Weckwerth-Pineda used the scope on his own rifle to spot Sik's shots. Weckwerth-Pineda and Sik admit
at least one shot struck and ruptured the pipe. Later that day, Weckwerth-Pineda and Sik returned to the ar-
ea and saw that the pipeline was leaking and reported the leak to the authorities.
According to court documents, the owner of the pipeline, Magellan Midstream Partners, L.P., claimed that
the pipe's rupture caused at least 3,906 gallons of diesel fuel to spill into Judicial Ditch 24 at a cost of approxi-
mately $1,122,617.64 to clean up the spill and repair the pipeline. The Environmental Protection Agency also
expended $16,154.42 in as-
sisting in the clean-up opera-
tion.
"We hope that the sentencings
cause people to think twice
before engaging in irresponsi-
ble and reckless behavior in
the vicinity of an active pipe-
line," said Andrea M. Kropf,
Special Agent-in-Charge, Mid-
western Region, U.S. Depart-
ment of Transportation Office of Inspector General.
"Working with our federal law enforcement and prose-
cutorial partners, we will continue our vigorous efforts
to protect the safety and integrity of the pipeline trans-
portation system, as well as our nation's natural re-
sources and environment."
The case was investigated by EPA's Criminal Investiga-
tion Division, the Department of Transportation Office of
the Inspector General, the U.S. Coast Guard, the Lyon
County Sheriff's Office, and the Lyon County Attorney's
Office. This case was prosecuted by DOJ.

Sentencings
Former North Dakota Maintenance Supervisor Sentenced for Obstruction of OSHA Investi-
gation Into Death of Cargo Tank Welder
On October 14, 2021, the U.S. District Court for North Da-
kota sentenced Stephan Reisingerto time served, 18
months of supervised release, and a $100 special assess-	y
ment. On March 8, Reisinger pleaded guilty to one count of j
obstruction of an Occupational Safety and Health Admin-
istration (OSHA) proceeding. Reisinger was a maintenance	JF .
manager at Nabors Completion and Production Services
Company (NCPS) in Williston, North Dakota. On October 3,
2014, an NCPS employee was fatally injured in an explo- r ^
sion while welding on an uncleaned tanker trailer that had
been used to transport produced water, a liquid byproduct	^ '
generated during the extraction of oil and natural gas. Dur-
ing OSHA's investigation into the employee's death, Reisinger falsely stated that "just water" was in the tanks
but, in the plea agreement, admitted to knowing the tanker trailers transported produced water, which can
contain flammable chemicals.
DOT-OIG conducted the investigation with OSHA, EPA's Criminal Investigative Division and the Bureau of Al-
cohol, Tobacco, Firearms, and Explosives.

Plea Agreements
Environmental Consulting Firm's Former Chief Executive Officer Pleads Guilty to Submitting
Hundreds of False Monitoring Reports
The former CEO and co-owner of an environmental consulting firm pleaded guilty on October 26, 2021 to
fabricating discharge monitoring reports required under the Clean Water Act and submitting those fraudulent
documents to state regulators in Tennessee and Mississippi.
According to court documents and information in the public record, DiAne Gordon, 61, of Memphis, was the
co-owner and chief executive officer of Environmental Compliance and Testing (ECT). ECT held itself out to
the public as a full-service environmental consulting firm and offered, among other things, sampling and
testing of stormwater, process water and wastewater.
Customers, typically concrete companies, hired ECT to take samples
and analyze them in a manner consistent with Clean Water Act permit
requirements. Gordon claimed to gather and send the samples to a full
-service environmental testing laboratory. The alleged results were
memorialized in lab reports and chain of custody forms submitted to
two state agencies, Mississippi Department of Environmental Quality
(MDEQ) and the Tennessee Department of Environment and Conser-
vation (TDEC), to satisfy permit requirements. In reality, Gordon fabri-
cated the test results and related reports. She even forged documents
from a reputable testing laboratory in furtherance of her crime. Gor-
don then billed her clients for the sampling and analysis. Law enforce-
ment and regulators quickly determined that Gordon created and sub-
mitted, or caused to be submitted, at least 405 false lab reports and chain of custody forms from her compa-
ny in Memphis to state regulators since 2017.
Pursuant to the terms of her plea agreement, Gordon will pay $201,388.88 in restitution to the victims of her
crime.
"By fabricating these reports, Gordon betrayed her position of trust and violated her responsibility to provide
information critical to evaluating water quality for residents in Tennessee and Mississippi," said Assistant
Attorney General Todd Kim of the Justice Department's Environment and Natural Resources Division. "This
prosecution shows the value of state and federal partnerships in investigating and prosecuting fraud and up-
holding the nation's environmental laws for the good of public health."
"The Clean Water Act ensures that water quality is maintained throughout the United States," said Acting
U.S. Attorney Joseph C. Murphy Jr. for the Western District of Tennessee. "Correct and accurate test results
of discharges into rivers and stream and the honest reporting of those results to regulatory authorities are
important parts of the Act's regulatory framework. Without accurate test results and reporting of those re-
sults, the Clean Water Act will not work as Congress intended. Because honest reporting of this data is so im-
portant to the functioning of the Act, our office will vigorously prosecute individuals who falsely report test
results."
"The defendant's job was to help her clients remain in compliance with the Clean Water Act but instead she
Gordon fabricated the
test results and
related reports. She
even forged
documents from a reputable
testing laboratory in furtherance
of her crime. Gordon then billed
her clients for the sampling and
analysis.

chose to falsify the required analytical testing under the Act for financial gain," said Special Agent in Charge
Charles Carfagno of the Environmental Protection Agency - Criminal Investigation Division's (EPA-CID) South-
east Area Branch. "The guilty plea illustrates the consequences of such criminal behavior and that EPA-CID
will continue to vigorously investigate those that choose to violate our environmental laws."
Gordon pleaded guilty to knowingly and willfully making and using false writings and documents in a matter
within the jurisdiction of EPA. She is scheduled to be sentenced on March 22, 2022, and faces a maximum
penalty of five years in prison. A federal district court judge will determine any sentence after considering the
U.S. Sentencing Guidelines and other statutory factors.
The case was investigated by EPA's Criminal Investigation Division, with assistance from the Mississippi De-
partment of Environmental Quality and the Tennessee Department of Environment and Conservation. The
case is being prosecuted by a DOJ litigation team.

Plea Agreements
Oklahoma City Diesel Engine Service Garage Owner Pleads Guilty to Violating the Clean Air
Act by Tampering with the Emissions Control Systems on Heavy-Duty Diesel Trucks
On October 7, 2021, James Love, 52, of Oklahoma City, pleaded guilty to a single-count felony Information
charging him with Tampering with a Monitoring Device and Method Required to be Maintained Under the
Clean Air Act, announced Robert J. Troester, Acting United States Attorney for the Western District of Okla-
homa.
"By causing the removal of pollution control devices, Love caused diesel trucks to spew pollutants into the air
at a rate of up to 300 times caused by normal operating vehicles," said Acting U.S. Attorney Troester. "This
conduct increased toxins in our environment linked to cancer and pulmonary, neurological, cardiovascular,
and immune system damage. To engage in this conduct for financial gain will not be tolerated."
"The defendant pled guilty to tampering with diesel truck monitoring systems required under the Clean Air
Act" said Special Agent in Charge Christopher R. Brooks of EPA's Criminal Investigation Division in Texas. "He
knowingly directed others to reprogram the trucks' Onboard Diagnostic (OBD) systems to prevent the detec-
tion of alterations to the emission controls, thereby exposing the public to significant levels of air pollution."
On September 20, 2021, Love was charged by Information with violating the Clean Air Act. Love owned and
operated Southwest Diesel Service, a heavy-duty diesel engine full-service garage located in Oklahoma
City. Love admitted that between February 2015 and April 2019, he directed his employees to modify the
emissions control systems on heavy-duty diesel trucks. Specifically, Love directed these employees to alter
the emissions control components, including removing the diesel particulate filters (DPFs) and plating the ex-
haust gas recirculation systems (EGRs). He then instructed others to reprogram the vehicles' on-board com-
puters so that the emissions control systems' sensors failed to detect the alterations. These modifications
prevented the trucks from accurately recording the pollutants they discharged into the atmosphere. They
also ensured that the trucks continued to travel on public roads despite operating illegally.
At sentencing, Love faces up to two years in prison and a $250,000 fine. A sentencing hearing will occur in
approximately 90 days from the date of the Plea Agreement.
The investigation was conducted by the Oklahoma Environmental Crimes Task Force which includes EPA's
Criminal Investigation Division and the Oklahoma Department of Environmental Quality's Criminal Investiga-
tion Unit. The case is being prosecuted by DOJ

Plea Agreements
Kansas Man Pleads Guilty to Water Facility Tampering
On October 21, 2021, Wyatt Travnichek, 23, of Lorraine, Kansas pleaded guilty to tampering with the comput-
er system at a drinking water treatment facility in Ellsworth County, Kansas. Travnichek pleaded guilty to one
count of tampering with a public water system and one count of reckless damage to a protected computer
system during unauthorized access.
According to court documents, the Post Rock Rural Water District hired Travnichek in January 2.018, and his
duties included monitoring the plant after hours using a remote log-
in system. Travnichek resigned his position in January 2019. On
March 27, 2019, the remote log in system was used to shut down
the plant and turn off one of its filters. Investigators established
Travnichek's ceil phone was used to perpetrate the intrusion, and
that the phone was in his possession at the time of the shutdown.
He told investigators he was intoxicated and didn't remember any-
thing about the night of March 27, 2019.
"Ensuring the security of our nations cyber infrastructure is one of
the FBI's top priorities and the plea underscores the joint dedication
to that effort by the FBI, EPA and the Kansas Bureau of Investigation. There is no doubt that Travnichek's in-
tentional actions directly placed the public in harm's way. The plea should send a clear message to anyone
who attempts to tamper with
public facilities - law enforcement
will remain resolute in investi-
gating any and all threats that put
the public's health at risk," said
FBI Special Agent in Charge
Charles Dayoub.
"Protecting America's drinking
water is a top EPA priority," said
Special Agent in Charge Lance Eh-
rig of the EPA's Criminal Investigation Division in Kansas. "EPA will continue our focused efforts with DOJ and
the states as we investigate and pursue any threats that might be directed toward vital community drinking
water resources."
The parties recommend a prison sentence of 12 months and one day on counts one and two to run concur-
rently. However, a district court judge will determine a sentence after considering the U.S. Sentencing Guide-
lines and other statutory factors.
The case was investigated by EPA's Criminal Investigation, the FBI and the Kansas Bureau of Investigation.
The case is being prosecuted by DOJ.

Plea Agreements
Contract Mail Carrier Pleads Guilty to Vehicle Smuggling Scheme - Child Pornography Dis-
covered During Investigation
Christopher Cox, 48, of Mason County, Washington resident pleaded guilty on September 20, 2021, in U.S.
District Court in Tacoma to three federal felonies related to a smuggling scheme and possession of child por-
nography, announced Acting U.S. Attorney Tessa M. Gorman. Christopher M. Cox pleaded guilty to smug-
gling goods into the U.S., making false statements related to the Clean Air Act and possession of child por-
nography. Cox will be sentenced on December 10, 202.1.
According to the plea agreement, between approximately 2015 and
January 2019, Cox falsified the required paperwork on two dozen
vehicles he imported from overseas. Many of the vehicles were ex-
tremely light vehicles imported from Japan that did not meet U.S.
safety standards. Cox sold some of the vehicles to contract mail car-
riers he knew from his job. Cox falsified the forms that claimed the
vehicles met both safety standards and Environmental Protection
Agency (EPA) Clean Air Act standards. Cox used his identification as
a contract mail carrier to circumvent inspections at the Port of Taco-
ma and took the vehicles from the Port without proper inspec-
tions. The total value of the imported vehicles exceeds
$55,000. Those who bought the vehicles were not told that they
failed to meet federal safety and pollution standards.
When law enforcement officers served search warrants on Cox's
electronic accounts, they observed images of child pornogra-
phy. Some of the images are known series of images of child rape
and abuse manufactured outside the State of Washington. When officers executed search warrants on Cox's
residence and obtained his electronic devices, they located 142 images and 2 videos of child molestation,
rape and abuse.
Smuggling of goods into the U.S. and possession of child pornography are both punishable by up to 20 years
in prison. Making false statements related to the Clean Air Act is punishable by up to 2 years in prison.
Under the terms of the plea agreement, the government will recommend no more than 63 months in pris-
on. The judge will determine the appropriate sentence after considering the U.S. Sentencing Guidelines and
other statutory factors.
The case was investigated by Homeland Security Investigations with critical assistance from U.S. Customs and
Border Protection (CBP). The case is being prosecuted by DOJ.

Indictments/Information
Horse Cave, Kentucky Man and Company Charged a Second Time for Violations of the Safe
Drinking Water Act
A federal grand jury returned an indictment on October 13, 2021, charging Charles L. Stinson and Logsdon
Valley Oil, Inc., a.k.a. Hart Petroleum, with a violation of the Safe Drinking Water Act.
According to the indictment, Stinson, 84, of Horse Cave, Kentucky, and the company, Logsdon Valley Oil, Inc.,
on or about September 13, 2019, willfully injected fluids into a sinkhole that was not permitted and author-
ized by rule for underground injection, at Payton #7 East lease, permit number KYI0420.

Indictments/Information
Signal Peak Energy Admits Violating Health, Safety Regulations at Montana Coal Mine
On October 7, 2021, Signal Peak Energy, LLC, which operates an underground coal mine near Roundup, Mon-
tana, admitted to criminal charges that it willfully violated health and safety standards and has agreed to pay
a $1 million fine as part of proposed plea agreement, Acting U.S. Attorney Leif M. Johnson said.
Signal Peak Energy, through a representative, pleaded guilty during an initial appearance and plea hearing to
an information charging it with four counts of willful violation of a health and safety standard, a misdemean-
or. The maximum penalty is a $250,000 fine.
A plea agreement recommends that a criminal fine of $250,000 for each count of conviction, for a total fine
of $1 million, is the appropriate disposition of the case. The parties further agree that a sentence of proba-
tion is appropriate. If the court accepts the plea agreement, the company does not have an automatic right
to withdraw its guilty pleas. If the court rejects the plea agreement, the company can withdraw its guilty
pleas and proceed to trial.
U.S. Magistrate Judge Timothy J. Cavan presided. A sentencing date before U.S. District Judge Susan P.
Watters has not yet been set.
"Signal Peak's conduct showed a blatant and callous disregard for its own workers' health and safety and for
protecting the environment. Companies that habitually and willfully violate regulations will be investigated
and prosecuted to the full extent of the law," Acting U.S. Attorney Johnson said.
The Signal Peak Energy prosecution is part of a broad corruption investigation into mine management and
operations that resulted in not only worker safety and environmental misdemeanor convictions, but also in
individual convictions and charges for some former mine officials and associates for embezzlement, tax eva-
sion, bank fraud, money laundering, drugs and firearms violations.
Individual convictions of former mine officials included Larry Wayne Price, Jr., former vice president of sur-
face operations, who was sentenced to prison for defrauding companies of $20 million; and Zachary Ruble,
former surface mine manager, who was sentenced to probation for conspiring to defraud Signal Peak Energy
of $2.3 million.
A third former mine official, Dale Lee Musgrave, former vice president of underground operations, has plead-
ed not guilty to an indictment alleging cocaine trafficking and false statements in mine records and is pending
trial.
Associated individual cases include Stephen P. Casher, a former Rocky Mountain Bank loan officer, who was
sentenced to prison and fined on bank fraud and money laundering charges for a loan scheme involving Larry
Price Jr.; James and Timilynn Kisling, owners of Kisling Quality Builders, who were sentenced to probation and
fined for conviction of tax evasion in a scheme involving the construction of Larry Price Jr.'s Billings residence;
Mark Luciano, a Nevada resident who was sentenced to prison for conviction on trafficking cocaine; and Todd
Alan Irwin, a secretary to Larry Price, Jr., who was sentenced to probation for conviction of felon in posses-
sion of firearms.

Indictments/Information
Robert Wayne Ramsey, owner of Peters Equipment Company, has been charged by an information with wire
fraud in an alleged equipment sale scheme involving Signal Peak Energy and is pending arraignment.
In the Signal Peak Energy case, the government alleged in court documents that from 2013 through 2018,
Signal Peak Energy habitually violated mandatory health and safety standards in the Mine Safety and Health
Act during the mine's operation. These violations included both environmental safety and worker safety
standards. These violations also occurred with the full knowledge, direction and participation of the mine's
most senior management during that period, including the president and CEO, the vice president of surface
operations, the vice president of underground operations and the safety manager.
The government further alleged that during the summer of 2013, Signal Peak Energy's senior managers di-
rected mine employees to improperly dispose of mine waste by pumping the waste into abandoned sections
of the mine. This waste, known as "slurry," consisted of wastewater, industrial chemicals used in the mining
process and unprocessed soil containing heavy metals, including arsenic and lead over groundwater toleranc-
es. Mine employees pumped this slurry into the abandoned section of the mine for about two weeks, until
the section was full. Disposing mine waste in this manner required approval of both the Mine Safety and
Health Administration (MSHA) and the Environmental Protection Agency (EPA), which Signal Peak Energy did
not obtain.
In the spring of 2015, the government alleged, Signal Peak Energy agents commissioned the drilling of two
bore holes through the ground that led to another abandoned section of the mine. Senior mine managers
directed employees to pump more slurry into the abandoned section through the bore holes. This slurry was
similar to the slurry improperly disposed of in 2013. Estimates vary, but this pumping occurred for up to six
weeks. The pumping stopped after a witness discovered that seals between the abandoned mine works and
the operating mine had been breached, causing flooding in the areas of the operating mine. Signal Peak Ener-
gy obtained a permit to inject water into the ground through the bore holes, but this permit did not allow for
the disposal of slurry waste.
In January 2018, Signal Peak Energy failed to report as required the injury of an employee, identified as John
Doe 1, who was working at the mine when his finger was crushed and required amputation. Doe 1 was mov-
ing large mining equipment as part of his duties when some of this equipment fell onto his hand. Doe lmet
with the safety manager, who began driving him to the hospital for medical treatment. On the way, Doe 1
had a telephone conversation with the vice president of underground operations. The vice president of un-
derground operations pressured Doe 1 not to report the injury as work related and said that he would make
it worthwhile for Doe 1. The safety manager witnessed this but did not intervene. The safety manager then
dropped off Doe 1 at the hospital rather than accompanying him inside pursuant to mine policy. Doe 1 falsely
stated that the injury had occurred at home and was not work related. When Doe 1 returned to work some-
time later, the vice president of underground operations gave Doe 1 an envelope containing $2,000.
In May 2018, Signal Peak Energy again failed to report an injury as mandated. An employee, identified as
John Doe 2, was working in the underground portion of the mine when rock sluffed off the wall and onto Doe
2's head, causing a severe laceration. The shift manager immediately called the safety manager. The safety
manager met Doe 2 and drove Doe 2 away from the mine with the stated intention to take Doe 2 to the hos-
pital. Instead, the safety manager drove Doe 2 home. Doe 2 waited until the next morning to seek medical
attention and falsely stated the injury had been caused by a shelf falling on his head in the garage of his

home. Doctors treated the laceration and Doe 2 returned to work for his next scheduled shift. Doe 2 was un-
able to complete the shift or several of the following shifts because of his injuries. Doe 2's lost time was
charged against his vacation leave without his approval.
The case is being investigated by EPA's Criminal Investigation Division, IRS and FBI. The case is being prose-
cuted by a DOJ litigation team.
An indictment is merely an allegation and all defendants are presumed innocent unless and until proven guilty
beyond a reasonable doubt in a court of law.
