Final Delegation Agreements

ADEQ is authorized to delegate some of its environmental regulatory functions, powers or duties to a local environmental agency, county health department, public health services district or city agency.¹  ADEQ’s rules continue to apply statewide, but delegated agencies may also have separate authority to impose compliance standards that are stricter than those in ADEQ's rules.
