Fly ash management
Fly ash consists of fine particulates that are captured in the Waste-to-Energy Facility's air pollution control system. These particulates are a mixture of ash from the combustion process and lime and carbon which are added to capture acid gases and mercury. Before being transported and disposed, fly ash is treated to reduce the potential of certain heavy metals to leach out – this is done by chemically binding the metals in the fly ash.
Fly ash is removed from the air pollution control system and stored in a silo. From there, it is periodically loaded to a trailer, from which a sample of the ash is collected and tested. Once test results are received back from the lab confirming the fly ash is non-hazardous, the ash is disposed of at a landfill. Reports are posted quarterly.
