A Baltimore propane distribution company filed for punitive damages against owners of the cargo ship Dali, saying it suffered economic losses from the Francis Scott Key Bridge collapse.

Underwood Energy alleged in a complaint that Grace Ocean Private Ltd. and Synergy Marine Pte Ltd. allowed a vessel with known power supply issues to continue operating, resulting in “carelessness, negligence, gross negligence, and recklessness” and its business being “crippled by this national disaster.” The company first launched the lawsuit Tuesday.

Synergy Marine spokesperson Darrell Wilson said in an email that, “Unfortunately, due to the ongoing investigations, in which we are fully participating and the legal proceedings, it would be inappropriate for us to comment at this time.”

The Key Bridge was the main route for companies like Underwood Energy to haul hazardous materials through Baltimore. Without it, hazmat trucks have to take a 35-mile detour through the increasingly congested Interstate 695 beltway. The workaround is losing Underwood Energy significant profits, according to the lawsuit filed in the U.S. District Court of Maryland.

This state-mandated route stems from regulations that prevent most hazmat trucks from using local tunnels due to safety concerns if an accident or spill occurred. A Baltimore Banner investigation found that after the Key Bridge collapsed, some hazmat drivers were illegally using the tunnels.

From a parking lot wedged between the two tunnels, Banner journalists observed 40 tanker trucks going through the Baltimore Harbor Tunnel, including more than a dozen with hazmat placards, which indicate the vehicles are typically prohibited from driving through the underpasses.

A half-dozen truckers interviewed for the story also said some are removing the placards before driving through the tunnels, leaving police and first responders with significant blindspots. Law enforcement uses placards to help identify possible violations, and first responders need them to inform their responses in an emergency.

Traffic delays may be a minor inconvenience for most drivers, but for truckers it often comes at a significant financial cost. Most are paid by the mile and are not further compensated for slowed traffic or congestion.
