West Covina : Hearing on Leachate Plant

The state Department of Health Services and the U.S. Environmental Protection Agency will conduct a hearing at 7:30 p.m. March 2 at West Covina City Hall on a proposed permit that would allow BKK Corp. to build a leachate treatment plant at its landfill in West Covina.

The plant would detoxify leachate, which can be liquid waste or rainwater that has picked up contaminants by passing through waste or liquid that was created from waste decomposition. The treated liquid could be used for dust control at the dump or be discharged into the sewer. The residue, a sludge cake, would have to be transported to a hazardous waste dump.

State health officials said the plant would be designed to treat up to 50,000 gallons of leachate a day and could be expanded to twice that capacity, if needed. The plant could only treat leachate generated at BKK and would not be used to treat leachate from other dumps, officials said.
