This next phase will be required only if after implementation of Phase 2 activities it is determined that compliance with TMDL nutrient targets and attainment of water quality objectives may not be achieved under completed and ongoing water quality control activities. If Phase 3 is deemed necessary, not only would additional water quality projects be evaluated for implementation, but modification to applicable beneficial uses and water quality objectives also would be considered, as discussed below.
