David L. Feldman,1∗ Ashmita Sengupta,2 Lindsey Stuvick,3 Eric Stein,2 Vin Pettigrove4 and Meenakshi Arora5 This article explores governance issues in developing innovative pollutant offset programs by focusing on a case study being piloted at the Gisborne Recycled Water Plant in Jackson Creek, a rural subcatchment of the Maribyrnong River north of Melbourne, Australia. The article offers preliminary lessons from the ongoing design and anticipated challenges facing this innovative program based on reflec- tions from the literature and project progress to-date. This case exemplifies a form of adaptive governance—an approach well suited to achieving broad sustainabil- ity objectives—and for which an early assessment is both appropriate and oppor- tune. Adaptive governance is characterized by governmental collaboration with civil society groups, social learning through public participation, and experimen- tation leading to more flexible policy outcomes. Early assessment affords the pos- sibility of midcourse corrections, drawing on experience acquired elsewhere. We contend that the approach being developed in Victoria through this pilot program has implications beyond the use of recycled wastewater for achieving various social objectives. It may also contribute to the development of an expansive water quality offset framework applicable to point source discharges, nonpoint source pollution, and sewerage overspills. Moreover, the approach can be applied to design of off- set systems elsewhere—with appropriate economic savings and effective applica- tion to multiple water quality challenges if potential problems are discerned early. © 2015 Wiley Periodicals, Inc.
