Elon Musk’s tunneling firm, The Boring Company, has been fined nearly $500,000 by a Nevada environmental regulator for illegally dumping drilling fluids into manholes around Las Vegas — a move that caused “substantial damage” to public infrastructure, according to a notice of violation issued last week.
Inspectors Say Workers Ignored Orders to Stop Dumping
The Clark County Water Reclamation District (CCWRD) alleges that earlier this summer, Boring Company employees refused to stop discharging drilling fluids when inspectors arrived at a project site near central Las Vegas.
According to the violation, inspectors directed workers to halt the dumping, but the company resumed operations the following day after a manager believed regulators had left the area.
CCWRD crews later had to remove 12 cubic yards of drilling mud, spoils, and solid waste from a sewage treatment facility due to Boring’s illegal discharges across two project sites.
The fluids reportedly included MasterRoc AGA 41S, a chemical compound that can cause severe burns. Several Boring employees have previously reported chemical injuries after direct exposure to the mixture of drilling fluid and tunnel debris.
Nearly Half-Million Dollar Fine and Legal Violations
CCWRD said Boring’s actions violated federal wastewater and environmental laws, prompting a total fine of $493,297.08. That includes $131,297.08 to reimburse the district for cleanup costs.
The regulator cited the “egregious nature” of the violations, the damage to public infrastructure, and Boring’s acknowledgment of responsibility as factors in determining the penalty.
In the past three years, CCWRD has issued only one other fine exceeding $100,000 for wastewater-related violations, according to documents obtained by Fortune through public records requests.
Boring Company Acknowledged Wrongdoing
During a hearing in late September, several Boring executives attended a meeting with CCWRD officials and acknowledged responsibility for the violations. The company also agreed not to expand to new drilling sites until certain environmental conditions were met.
In a letter sent on August 15, Boring’s legal director admitted that “water was improperly discharged to the sewer system” and said the company had disconnected sewage lines and sealed leaks in its tunnels as corrective measures.
A current Boring employee, speaking anonymously to Fortune, confirmed that workers had been pumping drilling fluids directly into sewer systems without pretreatment, in violation of county rules.
“Feigned Compliance” and Misleading Inspectors
The regulator’s cease-and-desist letter accused Boring’s superintendent, Filippo Fazzino, of “feigning compliance.” Inspectors said he appeared to remove illegal connections when ordered but reinstalled them immediately after assuming regulators had left the property.
“TBC’s brazen refusal to stop its illicit discharges after being caught in the act, coupled with false statements to District inspectors, proves TBC’s activities to be knowing and intentional,” the letter stated.
Fazzino did not respond to multiple requests for comment.
Pattern of Environmental and Safety Violations
Founded in 2017, The Boring Company has faced repeated scrutiny for safety and regulatory lapses in Nevada. The company aims to build underground transportation tunnels for Teslas, creating what Musk calls an “underground highway system.”
Boring has raised more than $900 million from investors including Sequoia Capital, but progress has been limited. Its 4-mile Las Vegas Convention Center tunnel remains the only operational example of the project.
In September 2024, Nevada’s Bureau of Water Pollution Control fined the company $250,000 for nearly 800 environmental violations, including discharging untreated groundwater and failing to report spills. In 2022, Boring also entered a settlement agreement for similar issues.
Previous Infrastructure Damage in Las Vegas
In June 2023, Boring workers accidentally exposed the foundations of two monorail pillars while searching for irrigation lines beneath Las Vegas. Regulators ordered a temporary shutdown of the monorail, and Clark County issued three violations for unpermitted work and creating potential hazards.
The Las Vegas Convention and Visitors Authority (LVCVA), which contracts Boring to operate the tunnel system beneath the Convention Center, said it was “reviewing the documents” and declined further comment.
Ongoing Safety Investigations
Boring is also under investigation by Nevada OSHA, which cited the company eight times in 2023 for workplace safety violations. Several employees reported chemical burns from tunnel waste exposure. The company is contesting those citations and is expected to appear before regulators in an upcoming hearing.
A Growing List of Regulatory Challenges
The latest fine adds to a mounting list of legal and environmental challenges for Elon Musk’s tunneling startup. As Boring continues work on its Las Vegas tunnels, regulators say the company must meet strict conditions before any expansion — signaling that oversight of the ambitious underground project will only intensify.
