Comparison: State vs. Federal
• Rules. Arizona has adopted the federal regulations that define a waste that exhibits the characteristics of ignitability, corrosiveness, reactivity, or toxicity as a hazardous waste, with some minor modifications. Arizona has added several state regulations, primarily to modify specific sections of 40 CFR 261 in order to add references to Arizona hazardous waste citations or references to ADEQ. However, unlike the federal rules, those claiming the exclusion from hazardous waste found at 40 CFR 261.4(b)(6)(i) for wastes that fail the test for the toxicity characteristic because chromium is present must provide documentation to ADEQ that the exclusion's requirements have been met (AZ Admin. Code R 18-8-261(C)(i)). See the national section CHARACTERISTIC WASTE for more information.
• Administration and enforcement. Arizona's hazardous waste program, including the requirements for identifying characteristic wastes, are administered and enforced by ADEQ.
