Factors for Success in Developing Use Attainability Analysis

A Use Attainability Analysis (UAA) is a process to review and potentially modify a waterbody's designated uses, when the uses are not existing or attainable. This research identifies factors for success by analyzing key challenges faced in the UAA process and reporting on the common lessons learned. UAA case studies were analyzed to develop 29 findings. The findings, or factors for success, focused on five broad categories of criteria: scientific and technical understanding; legal and regulatory requirements; financial needs and impacts; public awareness and involvement; and regulatory agency preparedness. These findings were transformed into recommendations for activities or approaches that would be supportive of UAA efforts. The research included special focus on the following nationwide, emerging areas of importance for the UAAs: wet weather impacts, urban settings, and effluent-dependent or dominated streams.
