Businesses that emit the largest amounts of air pollutants in our jurisdiction, and other businesses as required by the U.S. Environmental Protection Agency, are regulated under Title V of the federal Clean Air Act. Each Title V business is required to hold an air operating permit.
These comprehensive permits roll together air-related regulations, emission limits, monitoring, record keeping, and reporting requirements into a single document. Like all of our permits, air operating permits help businesses know what they need to do to be in compliance, and they help us and the public hold these businesses accountable.
Emission totals listed for the Title V businesses on the map below are 2020 numbers (except for CO2e, which will be updated later in 2021).
