As Water Board investigates two Carmel Valley sewage spills, Cal Am explains what went wrong.
In the immediate aftermath of a sewage spill at Carmel Valley Ranch on Aug. 6 and then another on Aug. 16, California American Water officials were out on the scene right away, seeking to contain the overflow. Paperwork moves much slower. Months later, in response to a notice of violation issued on Oct. 26 by the Central Coast Regional Water Quality Control Board, Cal Am has filed a technical report explaining what the utility believes happened. … According to the water board’s findings, “Due to the proximity of the storm drain to the manhole and the County [Environmental Health Bureau of the Monterey County Health Department]’s observation that sandbags were not effective in stopping the overflow from entering the storm drain, Central Coast Water Board staff assume that up to 1,200 gallons of sewage discharged to the storm drain.”
