Comparison State vs. Federal
• Rules. Arizona adopts by reference the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in Arizona as of March 1, 2019, which includes standards that allow generators to accumulate hazardous waste on-site in containers. The federal container requirements include empty container standards and organic air emissions standards. There are no additional state requirements.
Owners and operators of hazardous waste treatment, storage, and disposal facilities (TSDFs) that use containers must comply with the state's permit application requirements and pay several state facility fees that are in addition to the container requirements specified in the federal rules. For more information regarding these state requirements, see the state section TSDF PERMITS.
• Administration and enforcement. The Arizona Department of Environmental Quality (ADEQ) administers and enforces the hazardous waste container rules in Arizona.
