SMOG ALERTS IN THE ‘80s
Ozone levels in the South Coast Air Basin have exceeded federal EPA standards 172 days so far this year, one of the worst records in the decade. But the number of days of more severe smog, as measured by first-stage and second-stage alerts, has been relatively low for the period.
The air basin covers Los Angeles, Orange, Riverside and San Bernardino counties.
