Salton Sea Air Quality Mitigation Program
Comprehensive, science-based, adaptive program
• Proactively identify and provide options for mitigating dust emissions from the playa
Components1) Annual emissions monitoring and prioritization2) Dust control strategy, planning, and design3) Dust control implementation & monitoring

01 – Annual Emissions Estimates
Objectives: o Where and when emissions occur?
o How much dust (PM10) is emitted?
Components:o Map Playa Exposure
o Characterize Playa Surfaces
o Model Wind Conditions
o Estimate Emissions

01 – Annual Emissions Estimates
Proactive Dust Control •Project prioritization•80% of the emissions
originate from 20% of the playa acreage
