Constraints

• Goals, Objectives and Constraints (Feb. 21, 2006)

– No stream flow alterations that result in additional negative impacts to lower basin uses – No stream flow alterations resulting in need to revise NPDES permits – No increase in NYC or NJ diversion rates without flow augmentation storage – No significant increase in drought frequency or storage drawdown – No significant reduction in out of basin diversions
