CLEVELAND -- General Environmental Management in Cleveland's industrial Flats has been closed since the city forced it to shut down after an April 20 explosion.

City leaders and residents went to court on Thursday, seeking a temporary restraining order against the company to keep the plant closed.

Even before the explosion, the city was investigating the company for safety issues, and health officials got so many complaints about a foul odor coming from the plant that the Ohio Environmental Protection Agency demanded that the plant fix the odor problem.
