4/9/15 UPDATE: The overflow has been stopped, according to the city, after an estimated 23,000 gallons of sewage spilled into Armistead Run from a broken 24-inch sewer pipe.
The Department of Public Works is working to stem an ongoing sewer overflow into Armistead Run, a tributary of Herring Run, near Federal Street in East Baltimore.
At the present rate of 100 gallons a minute, the amount of sewage is expected to exceed 10,000 gallons, the department reported.
The stream has been posted with warning signs – and cleanup operations will continue until the overflow is contained, DPW said.
The spill has been reported to the Maryland Department of the Environment, as required by law, and to city health officials. Herring Run flows into Back River in Baltimore County.
