Hicks & Company has conducted regulatory impact assessments on four sets of proposed rules affecting water quality, quantity, and aquifer management: Regulated Substance Tank Rules; Well Construction, Operation, Maintenance and Closure Rules; Demand Management and Critical Period Management Rules; Groundwater Withdrawal Permits, Aquifer Recharge, Storage, and Recovery Projects Rules. Each of the rules assessments analyzes potential impacts to the Authority, the regulated community, the aquifer and aquifer-related resources, and longer term or indirect social and economic effects. The assessments are generally based on the application of available data and previous research and studies performed by the Authority. In addition, a significant amount of additional information was collected through interviews with stakeholders including the regulated community, groundwater users, and other professionals who might be impacted by the proposed regulations.
