LADWP is currently managing the implementation of the Owens Lake Dust Mitigation Program to reduce emissions of particulate matter less than or equal to 10 microns in diameter (PM10) to meet state and federal air quality standards. The OLDMP is operated in compliance with Agreements with the Great Basin Unified Air Pollution Control District (GBUAPCD) under the authority of California Health and Safety Code Sec. 42316, legal settlement agreements with GBUAPCD, lease agreements for use of state lands (administered by the California State Lands Commission), and other regulatory approvals. For over 12 years, LADWP has primarily relied on shallow flooding at Owens Lake to control PM10, which has resulted in the use of as much as 80,500 acre feet of water from the Los Angeles Aqueduct each year for dust control. As part of the Master Project, LADWP intends to use less aqueduct water for dust suppression at Owens Lake. In doing so, LADWP can enhance water supply reliability by making aqueduct water available for other beneficial uses.
