Last Chance to Comment on Unimin's Air Permit For Tunnel City Sand Mine



Tomorrow is the deadline for commenting on Unimin's air permit application for the Tunnel City sand mine. The Department of Natural Resources requires Unimin to get such a permit showing that it will build a facility that meets state and federal standards for air emissions. In Unimin's case, that means that they have to build a mine and processing plant with controls that will limit emissions and the release of particulate matter. There are limits on emissions for particulate matter that is ten microns or less or 2.5 microns or less.
