Welcome
Welcome to the Utah Division of Air Quality's (UDAQ) State and Local Emissions Inventory System (SLEIS), a web-based application allowing permitted facilities to compile and submit data on point source emissions as required for facilities identified in Utah Rule R307-150 as outlined in 40 CFR Subpart A - Air Emissions Reporting Requirements.
Please Note:
The minimum browser requirements for SLEIS are currently Chrome, Microsoft Edge, or Mozilla Firefox versions. We have found several sources having difficulty with the software if they use Internet Explorer, and recommend using one of the above browsers instead.
