BAY POINT -- Work started this week to clean up a former wastewater treatment unit at the General Chemical plant.
The three-month-long project will remove soil and sediment and then backfill the lagoon area with clean soil, gravel, rock and clay, according to the state Department of Toxic Substances Control, the lead agency overseeing the work being by General Chemical.
In approving General Chemical's cleanup plan, the department determined it would not result in any significant negative environmental impacts.
The cleanup project will be done from 7 a.m. to 5 p.m. weekdays and is expected to be finished by the end of October. The excavated soil and sediment will be disposed off-site in accordance with state and federal regulations.
Before it was closed in 2008, the wastewater treatment unit received stormwater and non-contact cooling water that was discharged into Suisun Bay under a federal permit.
