California air board says DWP must control dry lake bed's dust

The California Air Resources Board has ruled that the Los Angeles Department of Water and Power is solely responsible for controlling the choking dust storms that arise from the dry Owens Lake bed.

The board said the DWP must take additional air pollution control measures on 2.9 square miles of the dry lake, which was drained to provide water to Los Angeles. The powder-fine dust arising from the bed often exceeds federal health standards  http://www.latimes.com/news/local/la-me-1121-owens-20121121-001,0,1992213.photo
