Current approaches to calculating discharge limitations and the use and intent of water quality standards are examined. Flow variable discharge permits, in which the amount of pollutant that may be discharged is based on the magnitude of the flow in the stream, are introduced as an alternative permit strategy that could reduce the cost of pollution control in certain instances while still meeting instream water quality objectives. Several possible designs of flow variable discharge permits are presented to show the flexibility of the concept; for example permits can be based on instantaneous flows, seasonal flows, trigger values, and ranges of flows. $
