citizen suits; environment

HB 2541 allows Arizona citizens directly harmed by environmental violations to sue polluters, the state, or local governments in court after giving 120 days' notice to both the violator and environmental authorities. The bill requires plaintiffs to prove their case and ensures state agencies have priority in enforcement - citizen lawsuits cannot proceed if the state is already investigating or prosecuting the violation. It also directs civil penalties collected from these lawsuits into Arizona’s Water Quality Assurance Revolving Fund, which must receive $18 million annually for environmental programs. This law expands private enforcement of environmental rules while prioritizing state-led action and funding water quality initiatives.
