FAR NORTHERN ISSUES

• Surrounding Land Use - Natural

- Anthropogenic

- Transport (Pacific, OR, WA, NV, Asia)

•Long-Term Strategy– Smoke Management– On/Off Road Mobile

• Species Reductions–Nitrates, sulfates, woodsmoke

- BART

- SB 656

SOUTHERN CALIFORNIA

• Species Analysis– Nitrates, Sulfates, OC, Coarse Mass, EC

• Attribution– Mobile Sources primarily; Boundary Transport

• Strategies (NAAQS non-attainment)– Diesel Risk Reduction, Goods Movement, BACM

REGIONAL HAZE BENCHMARKS for California Class 1 Areas • Lowest Hurdles

– coast at sea level

– lee of Sierra

• Highest Hurdles– southern Sierra

– southernmost C1As

• Regional Response to Reductions

• Gap Analysis

VISIBILITY IMPROVEMENT

• San Gorgonio GAP Analysis– Achieve 70% of 2018

deciview benchmark – 45% reduction in

nitrate extinction– 11% reduction in OMC;

37% reduction in EC– slight increase in

sulfate, coarse mass, and fine soil extinction

• Overall Trend is Improvement

WHO IMPACTS WHOM

• Uncontrollable Boundary Sources

• BART Sources

• Large Nearby Sources

• Caveats for Attribution Modeling Results

• Relative Percentage for Consultation>50% 25-50% <25%

Phase 1 Report TSSA: Combined Nitrate & Sulfate

REASONABLE PROGRESS

• Justify Reasonable Progress Goal using WRAP data analyses– Wildfires– Transport– Mobile sources, transportation corridors– Population growth and land use– Nearby stationary source facility

• Long Term Strategy– Explaining California SIP Commitments

– Don’t shoot the messenger!
