REDWOODS • Species Analysis Coastal Avg. Worst 18.45 dv – Haze Drivers – Seasonality TRINITY – Concentration Remote Forest Coast Range (lee) – Extinction Avg. Worst 16.32 dv • Geography LAVA BEDS Inland Plain – Terrain Avg. Worst 15.05 dv – Meteorology
LASSEN VOLCANIC – Regional vs. Local Western Base of Mountain – Proximity to eight Avg. Worst 14.15 dv Class 1 Areas FAR NORTHERN ISSUES
• Surrounding Land Use - Natural - Anthropogenic - Transport (Pacific, OR, WA, NV, Asia) • Species Reductions –Nitrates, sulfates, woodsmoke •Long-Term Strategy – Smoke Management – On/Off Road Mobile - 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 GLIDE PATH BENCHMARKS

• 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
Phase 1 Report TSSA: Combined Nitrate & Sulfate • Relative Percentage >50% 25-50% <25% for Consultation 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!
