The Utah Air Quality Board has adopted the final part the state's plans, to make it easier for Wasatch Front residents to breathe -- particularly in the winter.
But several Utahns' raised assertions -- before the vote -- that the measures are not strict enough.
Department of Environmental Quality Director Bryce Bird says, this week's decision is one of the final steps in the state's clean air plan. It establishes requirements for large industrial sources -- so called "smoke stack industries."
The Environmental Protection Agency will now review the Utah recommendations.
