The White Pine mine in Michigan was a mostly defunct copper mine that was to have sulfuric acid poured into its shafts to leach out remaining copper without United States Environmental Protection Agency (EPA) oversight. Citing concerns over degradation to nearby Lake Superior, Bresette resigned an EPA position he held at the time. He became a spokesperson for the group "Anishinabe Ogitchida" as they staged a protest stopping the tanker cars from carrying the sulfuric acid across the Bad River Ojibwe reservation in Ashland County, Wisconsin. The Bad River Train Blockade brought media scrutiny to EPA process and the eventual end to any attempts to revive the mine.
