The resolution HCR2039 expresses the Arizona Legislature's opposition to any rules or regulations that require applicants for an assured water supply (AWS) certificate to demonstrate more than a one-hundred-year supply of water necessary for their proposed use. It emphasizes that the legislative intent behind the 1980 Groundwater Management Act does not authorize the Arizona Department of Water Resources (ADWR) to impose additional requirements beyond what is necessary to satisfy the water needs of the applicant for a century. The resolution asserts that any such requirements or conditions proposed by the ADWR or the Governor are contrary to Arizona statutory law and therefore null and void.

Furthermore, the resolution outlines specific conditions under which the ADWR cannot deny or withhold an AWS certificate, including the reliance on a combination of groundwater, surface water, or effluent, as long as the applicant can demonstrate sufficient water availability for the proposed use. It mandates that the Director of the ADWR must ascertain the maximum volume of groundwater deemed "continuously available" when evaluating applications. Overall, the resolution seeks to clarify and reinforce the legislative intent of the 1980 Groundwater Management Act, ensuring that applicants are not subjected to unnecessary burdens in proving their water supply capabilities.
