Opportunities to learn and give input

Map portal and records database search tool
The Air Pollution Control Division generates and receives many documents and data. We understand public records can be challenging to find, so we created an interactive map to make it easier. Learn more about using the mapping tool and how to find stationary sources:
The division hosted two tutorial webinars on the mapping tool in 2023:
- Tuesday, May 2, 2023
- Thursday, June 8, 2023
We use an online database to store different documents and data. You can find this information using the Public Access Viewer, in addition to the interactive map.
Visit the division's records website for more information.
