Document Description
The City of los Angeles Department of Water and Power (LADWP) is currently implementing the Owens Lake Dust Mitigation Program (OLDMP) on Owens Dry Lake in order to reduce exceedances of the state and federal particulate matter (PM10) air quality standards. LADWP construct and operates dust control measures (DCMs) on the lake in compliance with Agreements with the Great Basin Unified Air Pollution Control District (GBUAPCD) under the authority of California Health & Safety Code Sec. 42316, legal settlement agreements with GBUAPCD, lease agreements for use of state lands (administered by the California State Lands Commission (CSLC)), and other regulatory approvals. Phase 7a will expand and modify the existing system of dust control on the lake by installation of Best Available Control Measures (BACM) (Gravel Cover, Shallow Flooding and Managed Vegetation) on 3.1 square miles of area identified as emissive by GBUAPCD. In addition, 3 to 4 sq miles of existing Shallow Flooding dust control areas (DCAs) will be transitioned to a Hybrid dust control method. Hybrid dust control is a new concept that will incorporate a combination of the three BACM to minimize dust while conserving water sue on Owens Dry Lake.
