Underground Injection Controls

Underground Injection Control (UIC)

SB 1494 | Underground Injection Control Program

The Underground Injection Control (UIC) Program regulates the underground injection or discharge of six categories of hazardous and non-hazardous liquid and gas. While ADEQ has existing partial authority to administer the program under Title 49, it was insufficient to obtain primacy and did not include a funding mechanism for some well categories. New wells subject to UIC regulation will be necessary as new mining and desalination technologies are developed in the state. With the passage of this bill, ADEQ can begin the stakeholder process to improve program administration and eliminate duplicative regulatory requirements that currently exist between Arizona’s Aquifer Protection Permit (APP) Program and UIC regulations.  ADEQ is currently developing a schedule for the rule development stakeholder process.
