★ Community Reacts to the Idaho-Maryland Mine DEIR

Residents of Nevada County were shocked at the inadequacy of the 1000+ page Draft Environmental Impact Report for the proposed Idaho-Maryland Mine.

It not only described a huge number of impacts, but it was riddled with errors, omissions, and legal flaws. So many in fact, that both community reviewers and the Grass Valley City Council's independent review of the report called for the draft to revised and recirculated before moving to the final draft.

"We'll see many more impacts listed as 'significant and unavoidable' before its done," said Ralph Silberstein, President of CEA Foundation.
