Fugitive Dust Mitigation

Potential Health Risks of the Project

The Mayor, City Council, Planning Commission, and city staff have received many comments from residents regarding this development project. We have received feedback from the Department of Environmental Quality, the State Department of Health, the Traverse Mountain HOA, concerned residents, and health professionals. The City Council considered all comments and recommendations before the City Council granted final approval.

As a city, we continue to be sensitive to the potential health risks of current and future development in our city. As we do not have the resources or expertise to evaluate these concerns, we will continue to rely on the departments designated by the State of Utah to make recommendations in this area. We will continue to seek the counsel and advice of the Utah Department of Environmental Quality and the Utah Department of Health. We will direct community members to send concerns and complaints to the respective departments.

We acknowledge the potential health risks associated with air pollution of all forms. We will continue to do what is within our power to limit its impact on our community while allowing private property rights to be recognized. As such, we will be creating an Environmental Sustainability Committee to address health and environmental risks, including air pollution, vehicle idling, storm water pollution and other potential concerns. More information about this program will be coming in the near future.
