Comparison: State vs. Federal

Rules. Indiana follows the federal rules for release notification, and has established stricter requirements for excess air emissions and hazardous waste discharges. Any malfunction of air emissions control equipment must be reported to the Indiana Department of Environmental Management (IDEM) within 4 hours. The reporting requirements under the Indiana Spill Rule for releases of hazardous substances are in addition to reporting requirements under federal laws and regulations.

In addition to complying with the federal regulations for immediate action and notification of hazardous waste discharges during transportation, Indiana requires notification to state officials.

Administration and enforcement. The IDEM administers and enforces the state's release notification rules.
