A local environmental watchdog group says it has reached a legal settlement with operators of the Newby Island Resource Recovery Park landfill to curb toxic runoff into local waterways. Erica Maharg, managing attorney for San Francisco Baykeeper, said in an interview last month that in the four years the organization monitored Newby Island starting in 2012, the facility consistently released excessive levels of pollutants into Coyote and Lower Penitencia creeks in violation of the Clean Water Act.
