Despite our public hearing, letters, and comments all asking otherwise, the Utah Division of Air Quality has issued an approval order for Granite Construction to operate a mining and aggregate operation in Parley's Canyon. Although this doesn't green light the project, it is a troubling step toward full mining operation that will impact all of those who live in or near the canyon. Obviously our overwhelming opposition to the issuance of said permit at the public hearing held earlier this year fell on deaf ears. π
Their issuance says nothing about monitoring air quality in or near the canyon. The document has no dispersion modeling, no meteorological data, no discussion of canyon winds, no background air quality data, no downwind receptors, and no comparison to the National Ambient Air Quality Standards. The cover letter says comments were received and considered, but no response to comments is attached.
Here is the permit from DAQ: https://daqpermitting.utah.gov/DocViewer?IntDocID=166253&contentType=application/pdf
We have only until October 10 or 11 to submit written opposition. You can sign off on this letter we intend to submit. DM your name and address to be added to this letter: https://canyonrimiscommunity.com/wp-content/uploads/2026/09/Parleys_DAQ_Petition_Draft.docx
