Monday marked the start of phase one in the fire debris removal process for homes destroyed in the Carr Fire. The piles of ash left behind contain many unseen hazardous waste products. Because it’s considered a threat to public health, homeowners may not opt out of letting government do the initial cleanup. There’s no charge. Materials including heavy metals, asbestos, pesticides, cleaning chemicals and paint are being removed by the State Department of Toxic Substances control with help from Shasta County Environmental Health. An online dashboard allows the public to see when the removal is complete. That can be viewed at shastareddingrecovers.org. A meeting about the process will be held in the Redding City Council Chambers at city hall at 6 O’clock Tuesday.
