AuGeologist,

Thank you for the info.

You might let the Board of Supervisors know that by closing the range, they're now liable for cleanup costs - which can be staggering. (I'm not 100% certain of this, so carefully verify this with EPA before letting the board know.) To give you an idea of how onerous the requirements can be, see what the State of Colorado has to say on the subject at http://www.cdphe.state.co.us/HM/shootingrange.pdf

NRA-ILA says Nevada has a "range protection law", which may prevent a range from being shut down for noise issues. (Source: http://www.nraila.org/GunLaws/Federal/Read.aspx?id=74 and pages 50-52 at http://www.rangeinfo.org/resource_library/business/legal/50State-RangeProtectionLaws.pdf ) . However, it does not address escaping bullets.
