Who Regulates the Dust on the Roads to the Mine?
Haul routes are public and/or BLM multi-use roads, which the facility does not have full control or ownership over. The BAPC has authority to implement the Clean Air Act with achieving compliance with ambient air quality standards to a regional level, and BAPC is requiring implementation of best management practices to minimize fugitive dust. For more information about road jurisdiction and agreements outside of the BAPC permitted areas, please contact Douglas County or visit their Painted Rock Mine website.
How do I Report a Complaint to the BAPC?
To report complaints within the BAPC jurisdiction (ie. dust concerns inside the mine boundary), please email them to ndepairadmins@ndep.nv.gov (note date and time stamped photos and/or videos are helpful) or call our front desk (775-687-9349).
