Owens Lake Dust Mitigation

June 2013 - Owens Lake Dust Control Update - Presentation

Owens Lake is the largest single source of PM-10 in the United States.

Water was first diverted from the Owens River to the City of Los Angeles in 1913, and by 1926 Owens Lake was dry. Today, the Owens lakebed produces enormous amounts of windblown dust in exceedence of federal air pollution standards for particulate matter. Particulate pollution is generally associated with dust, smoke and haze and is measured as PM-10 , which is an acronym for particulate matter less than 10 microns in diameter. Breathing PM-10 can cause a variety of health problems. The National Ambient Air Quality Standard for PM10 is set at 150 µg/m³ for a 24-hour average. Studies of dust transport from Owens Lake show that the standard can be exceeded more than 50 miles away and expose many more people to violations of the PM-10 standard than just the residents near Owens Lake. The dust from Owens Lake affects about 40,000 permanent residents between Ridgecrest and Bishop.
