Plans are underway to develop an optimization module. This module will allow the user to input objectives, then loads and the optimal set of BMPs will be returned. BMP co-benefits, such as those related to habitat, are planned to be returned as well.
Cost Effectiveness of BMPs
Cost effectiveness analysis is a necessary component for implementing pollutant reduction strategies. The table below shows the cost of BMPs per pound of nitrogen, phosphorus, or sediment reduced. These are estimates that were developed with the 2013 progress scenario in CAST-2017 using the Draft Final 7/14/2017 model version. The data may be applied to similar scenarios, such as progress from other years. These values are not applicable to scenarios that differ substantially from a typical progress, such as a WIP.
BMPs are ranked to indicate their impact on the co-benefits evaluated. This information will be incorporated into CAST scenario results at a later date. In the meantime, the BMP co-benefit impacts are provided at the links below.
