Nutrient Trading is a voluntary program designed to identify and finance the most cost-effective solutions to reduce nutrient loads in a watershed. The program allows nutrient generating sources such as wastewater treatment plants to meet nutrient reduction requirements by acquiring nutrient reduction credits from another source like a farming operation.
Credits are generated when a source reduces its nutrient loads to a greater extent than is required. To generate reduction credits a nonpoint source, a farm for example, must first ensure that it is meeting baseline compliance, and then that it is meeting minimum requirements referred to as “threshold.” The installation of BMPs, which are above these baseline and “threshold” requirements, can then generate credits that are eligible for sale.
