The Nutrient Reduction Strategy Annual Progress Report is assigned to the Water Resources Coordinating Council and follows the Iowa Nutrient Reduction Strategy (NRS) ( nutrientstrategy.iastate.edu ) framework that is based on EPA recommendations provided in their March 16, 2001 memo, “Working in Partnership with States to Address Phosphorus and Nitrogen Pollution through Use of a Framework for State Nutrient Reduction.” The annual report provides progress updates on point source and nonpoint source efforts related to the action items listed in the elements of the strategy and updates on implementation activities to achieve reductions in nitrogen and phosphorus loads.

The Nutrient Reduction Strategy Annual Progress Report is compiled by the three lead agencies (Iowa Department of Agriculture and Land Stewardship, Iowa Department of Natural Resources and Iowa State University) of the Iowa Nutrient Reduction Strategy and presented to the Water Resources Coordinating Council. The report follows the Iowa Nutrient Reduction Strategy (NRS) (nutrientstrategy.iastate.edu) framework that is based on EPA recommendations provided in their March 16, 2011 memo, “Working in Partnership with States to Address Phosphorus and Nitrogen Pollution through Use of a Framework for State Nutrient Reduction.” The annual report provides progress updates on point source and nonpoint source efforts related to the action items listed in the elements of the strategy and updates on implementation activities to achieve reductions in nitrogen and phosphorus loads.

In this paper, we examine the design of permit trading programs when the objective is to minimize the cost of achieving an ex ante pollution target, that is, one that is defined in expectation rather than an ex post deterministic value. We consider two potential sources of uncertainty, the presence of either of which can make our model appropriate: incomplete information on abatement costs and uncertain delivery coefficients. In such a setting, we find three distinct features that depart from the well-established results on permit trading: (1) the regulator’s information on firms’ abatement costs can matter; (2) the optimal permit cap is not necessarily equal to the ex ante pollution target; and (3) the optimal trading ratio is not necessarily equal to the delivery coefficient even when it is known with certainty. Intuitively, since the regulator is only required to meet a pollution target on average, she can set the trading ratio and total permit cap such that there will be more pollution when abatement costs are high and less pollution when abatement costs are low. Information on firms’ abatement costs is important in order for the regulator to induce the optimal alignment between pollution level and abatement costs.
