Comparison: State vs. Federal
• Rules. Oklahoma adopts by reference the federal rules for Emergency Planning and Community Right-to-Know Act (EPCRA) hazardous substance and extremely hazardous substance inventory reporting and toxic release inventory (TRI) reporting requirements, with additional reporting and fee requirements. Tier 2 reports must be submitted electronically to the Department of Environmental Quality (DEQ). To review federal EPCRA reporting requirements, refer to the national section COMMUNITY RIGHT TO KNOW.
Oklahoma does not have a federally approved occupational safety and health worker right-to-know program; therefore, private sector employers are governed by the federal hazard communication requirements. Public sector employers in Oklahoma must follow the state hazard communication requirements. The state has adopted the federal hazard communication standard by reference. See the national sections
