Iowa Capital Dispatch: Pattison Sand Co. of Clayton has appealed the state’s triple rejection of its permit application to export Iowa water to western states by rail, and the Sierra Club has intervened to oppose the permit. The nonprofit environmental group on Tuesday noted it had filed an intervention with the Iowa Department of Inspections and Appeals, which plans to hold a hearing on the matter Nov. 9-10. “Our public resources are not for sale and should not be used for private profits,” said Jess Mazour, conservation coordinator for the Iowa Sierra Club.
