YOUNGSTOWN, Ohio - The company contracted by the City of Youngstown to perform work in the basement of the Realty Building when it exploded is now suing Enbridge Gas Ohio.

According to the lawsuit, which was filed exactly one year after the deadly blast, Greenheart Companies LLC is suing Enbridge Gas Ohio, as well as MS Consultants and 10 John Does who have yet to be identified.

Greenheart, whose owner Brian Angelilli also owns the Realty Building, was hired by the city for a sidewalk replacement project in the vicinity of Realty Tower that required for some work to be done in an underground vault.

While performing that work, a Greenheart employee cut a live gas line causing the natural gas explosion.

According to the suit, Enbridge had deactivated and decommissioned the gas line that ran to the vault adjacent to the building in 2015, but failed to comply with federal laws and regulations regarding the deactivation and decommissioning process.

The suit states that Enbridge, previously known as Dominion Energy, has been found to have violated pipeline safety regulations several time since 2012 resulting in several explosions.

These alleged violations include failure to keep records of abandoned natural gas lines, failure to properly decommission natural gas lines and failure to inspect natural gas lines.

The suit slams Enbridge saying the company should have warned Greenheart and its workers that the gas line was still active and the dangers of working in the area of an active gas line and not properly deactivating it prior to the work beginning.

Additionally, the suit grills engineering consultant MS Consultants, who was involved in the investigation, project management, planning and execution for the sidewalk project.

The suit states that MS Consultants did not properly identify the active gas line or coordinate with the gas company about shutting it off.

"Their failures were hidden, as only the defendants knew of these failures until the May 28, 2024 explosion," the suit reads.

Greenheart is demanding damages exceeding $25,000 in this case including punitive damages, pre-judgment and post-judgment interest and attorney fees.

21 News has reached out to both Enbridge Gas Ohio and MS Consultants for comment and we've received the following response from Enbridge:

"Our thoughts remain with those impacted by this event and their families. We're unable to comment on the suit brought forward due to ongoing litigation. We also remain a party to the NTSB's ongoing investigation and while federal regulations limit our ability to comment publicly, we remain committed to continuing to contribute to the investigation."

We are still waiting to hear back from MS Consultants.
