“It is ground level ozone (O3)...has been a problem for 40-50 years on hot days. Today’s forecast for the area of FR HQ (Fresno) was 78 ppb (Stage 3 of 6) actually topped out at 86 ppb today.”
What kind of O3 levels do you find in cities in other states? Houston. Las Vegas. Phoenix? Atlanta Georgia? Those states are not banning natural gas use in homes.
