Republican Sen. Tom Tiffany's measure would prohibit local governments from imposing new zoning ordinances on sand mines that are more restrictive than current ordinances. It also would protect sand mines from any other new local ordinance or license requirement if they're operating within the year before the changes are imposed.
Tiffany says the bill is meant to ensure local governments that don't support sand mines don't force them out of business with excessive regulations. The Sierra Club, however, has accused Tiffany of selling out local governments to the mining industry.
The Assembly and Senate mining committee are set to hold a joint public hearing on the bill Monday.
