This paper proposes a water quality trading design that addresses common implementation problems. Trading ratios, which are calculated from damages integrated over each source’s spatial zone of influence, drive the system to a socially cost-effective outcome. The design is applied to combined sewer overflow management in the Upper Ohio River Basin, where trading ratios can vary significantly among trading partners. The analysis shows that significant compliance cost savings are possible without incurring a penalty in terms of social damages or overall water quality despite a higher level of discharge relative to the command and control option.
