New Mexico lawmakers have rejected a statewide cap on student enrollment in charter schools. In more news, Congress decided in the 90's how much nuclear waste could be deposited in the Waste Isolation Pilot Plant located in Carlsbad, NM. When the facility hits the limit it is supposed to close. However, Department of Energy officials came back last year and said they'd like to recalculate how much waste can be stored at WIPP. Former Governor Susana Martinez signed off on the request. Now local watchdog groups have appealed that decision saying 30 percent more toxic waste will be stored in the desert. KUNM's Marisa Demarco talked with Steve Zappy who was a permit writer and project leader for WIPP with the New Mexico Environment Department for 17 years. He's now retired.
