The noxious odors coming from mixing asphalt at a Granite Construction facility on Thursday led to complaints from neighbors and the evacuation of nearby schools.
The Pima County Department of Environmental Quality ordered the company on Friday to temporarily cease producing asphalt at the companyโs Swan Road Plant, 9301 S. Swan Road, the department said in a news release.
Beginning Thursday, the department, Southwest Gas, 911, and poison control center received โheavy volumes of calls from individuals reporting the odor and expressing health concerns,โ the news release said. As a precaution, schools in the area were temporarily evacuated.
Officials with various local agencies worked with the department to find the source of the odors. They determined the Granite plant was the source and issued an order of abatement, the news release said.
โPDEQ will work with Granite Construction to resolve this asphalt odor issue so the company can continue its work while protecting public health,โ the news release said.
