F GRADE-02.png
pollutes our air

failing grade

Grass Valley gets an “F” for air quality today. The mine will make it worse with escaped dust from continuous rock crushing, loading, hauling, unloading, spreading, and compacting. With chronic lung disease deaths already at twice the state average, we can't afford any more.  


Air quality is one of our big concerns. The fact of the matter is that our community is already in a seriously compromised position. There's a long list of poor ratings we could cite, but the 2020 “State of the Air Report” from the American Lung Association, says it all. They gave Nevada County an “F” for our air quality, and that counted for both high ozone days and particle pollution. The reports Rise Gold paid for claims that the health risks posed by the mine will be “less than significant”, but we beg to differ. We believe the impact will be significant for this community. Health risks need to be assessed by independent organizations, such as the one preparing the Draft Environmental Impact Report.  


Here are some talking points that can help.

  • We already have very unhealthy air quality. We can't afford to make it worse.

  • Mining operations call for continuous truck trips. Transportation is the largest producer of carbon emissions in California.

  • Despite efforts to mitigate, there will be escaped fumes from blasting and processing.

  • Fugitive dust will escape from rock crushing, loading, and unloading as they create mountains of engineered fill. 

  • Nevada County's death rate from chronic lung disease is already twice the state average.

Listen to Pam Heard, Respiratory Therapist, give a 10 minute overview about the significant dangers the Idaho-Maryland Mine poses to the air we breathe.

Mine Would Add to Air Pollution

Read Nevada City resident Ray Bryars opinion piece, spelling out the health risks we already face with our "F" rated air quality and making a great case for why exposing the community to even more insults from a mining operation is unthinkable.
