 KFXZ 1520. I'm Jeff Palermo. The Danker Performance Elastomer Plant in St. John Parish has been accused of producing emissions that leads to higher cancer rates. In April, the EPA gave the chemical plant 90 days to lower its emissions, but on Monday, the Louisiana Department of Environmental Quality says it's giving Danker two years to meet the new emission requirements. DEQ Secretary Aurelia Giacometto says the 90-day timeline was not realistic.
