Nonpoint to Nonpoint Trading

A nonpoint source discharges pollutants from a diffuse area. Nonpoint source pollution enters a water body as runoff from a wide geographic area. Typical examples include polluted runoff from cities, suburbs, and agricultural fields, and air deposition of contaminants.

Nonpoint to nonpoint trading describes when a nonpoint source pays for more cost effective controls of polluted runoff elsewhere in its watershed. The incentive to trade may come from stricter controls that newer sources may face, such as a new housing development that must control its runoff to a higher level than previous developments in the same watershed.
