Arizona's Aquifer Protection Permit Regulations and Some Implications for the Mining Industry

Mining impacts to groundwater are being comprehensively regulated for the first time in Arizona with the implementation of the Aquifer Protection Permit Program. This far reaching program is one of the nation's strongest groundwater quality protection programs. Aquifer Protection Pennits (APPs) are required for almost all mining operations and will compel mining companies to pay increased attention to the potential groundwater quality impacts from their activities. All regulated mining operations will have to employ discharge control technologies and monitoring will be heavily emphasized. Technical requirements and relevant permit conditions are discussed.
