An explosion on a sewage boat docked on the Hudson River in New York City killed a city worker and injured two workers, officials said.

The New York City Fire Department Deputy Director David David Simms told reporters that three Department of Environmental Protection employees were docking vessels at the North River wastewater recycling facility in Siharin when the explosion occurred at about 10:30 a.m. Eastern Time.

The video captures a lot of black smoke rolling in.

Dep employee Raymond Feige was pronounced dead at the scene of the explosion, which occurred near Upper Manhattan's Upper 135th Street. Two other employees were taken to a regional hospital. No conditions are provided.

"After arriving, the unit found a large explosion in one of the tank's storages," Sims said. "The ship transported the original sewage from New York City to the sewage treatment plant."

Sims revealed that the victim of the deceased was “destroyed by an explosive force between the dock and the ship.”

A man driving in the area told CBS News New York that he felt the ground shake.

"I smelled something, I didn't know what that was, and then the next thing you know, boom," David Simon said. "I think something hit the floor because the truck dropped the load and caused vibrations throughout the park. As I got closer here, I heard there was an explosion on the boat."

Sims said the cause of the explosion is under investigation. The U.S. Coast Guard wrote on X that the "event" was "reported to be related to popular work on the docking ship."

"At present, there is no doubt that crime is committed and there is no impact on the facility," New York City Mayor Eric Adams said in a statement.

DEP Commissioner Rohit T. Aggarwala said in a statement released on Sunday that Feige has faithfully served the city for 33 years.

“Ray is a respected engineer and a stable, beloved colleague who will be deeply missed,” Aggarvara said. “For thirty years he worked at DEP, in a job that most New Yorkers are invisible to, which is essential to keeping the city running and we are very grateful for the service. Please continue to keep Ray’s family and colleagues in keeping your ideas in this difficult time.”

Adams said in a statement Saturday that he was “frustrated to hear Feige’s tragic death”, adding: “This devout civil servant has served New York City for 33 years and our hearts are all for his family, friends and colleagues during this painful period.”

A city official told CBS News in New York that the explosion did not appear to have any environmental impact.

The U.S. Coast Guard wrote in a social media post that Hudson did not report on pollution after the explosion, saying "the situation is stable."

Officials said the plant's operations were not affected.
