Updated Air Quality Ordinance

In 2015 the San Antonio City Council passed ordinance #2015-­­­­11-19-0967 requiring business facilities with air pollution emissions to register with Metro Health and pay an annual registration fee of $200.00 per facility.  This registration process will help identify local sources of ozone components and develop steps to lower emissions and improve air quality for residents. Below you can find the registration form, a copy of the ordinance and a helpful Q&A.
