owensdrylakenewState Air Board rules against Los Angeles Department of Water and Power in Owens Lake appeal

Date: November 19, 2012 

Press Release –

In a long awaited decision, the California Air Resources Board today ruled that the Los Angeles Department of Water and Power is required to construct additional air pollution controls on the dried Owens Lake bed.  The LADWP has opposed existing federal, state and local air pollution control laws because of the cost of the required controls.  LADWP’s water diversions from the Eastern Sierra cause the Owens Lake bed to be dry, creating the largest single source of fine particulate matter air pollution in the country.  Particulate air emissions are a danger to human health and the environment; the particulates lodge deep in the lungs, causing respiratory injuries and additional risks to children and the elderly.  Over the past year, LADWP’s operations have created dust storms exceeding the federal standard on 25 separate days resulting in the issuance of local health alerts.

In late 2011, the agency responsible for enforcing the law, the Great Basin Unified Air Pollution Control District, determined that an additional 2.86 square miles of the Owens Lake bed require dust controls in order to meet air quality standards in the Owens Valley.  The LADWP appealed Great Basin’s determination to the State Air Board and a hearing was held on the issues in Sacramento last June.  The Air Board’s decision supporting Great Basin was released today .

“The State Air Board found in favor of Great Basin on every one of the issues,” said Ted Schade, Great Basin’s Air Pollution Control Officer. “Having across-the-board support from the premier technical and legal air quality organization in the state is very gratifying. The ARB spent an entire year carefully evaluating all the LADWP’s objections and found no grounds for the LADWP’s claims that no additional controls are required.  Great Basin encourages LADWP to move forward immediately to protect the air quality of the Owens Valley.”
