he CEO and two employees of a Riverside County-based painting company were sentenced after pleading guilty to contaminating San Diego’s storm water system by power-washing painted curbs and allowing toxic lead paint chips to flow into storm drains, City Attorney Mara Elliott announced Friday. The trio were placed on probation and ordered to pay more than$12,000 in fines and restitution, Elliott said. Ochoa Striping Services Inc. was contracted to sandblast paint from curbs in a Del Cerro neighborhood, Elliott said. That method of paint removal would have allowed workers to safely clean up and dispose of hazardous material.
