To protect you and your loved ones, Mid-Ohio Regional Planning Committee issues alerts when air pollution levels are high in Central Ohio. MORPC uses the Air Quality Index (AQI) to report daily forecasts and Air Quality Alerts. The AQI tracks pollution levels in the air and tells us if the air is healthy to breathe. On most days, air quality is in the green or yellow range—good days to be active outside. But on several days each year, ozone and fine particle pollution can reach unhealthy levels, pushing AQI levels into the orange range—unhealthy for sensitive groups.
