All farmers who irrigate land within the Central Valley of California must complete an Irrigation and Nitrogen Management Plan (INMP) for any irrigated parcel of land.  If the parcel is located in High Vulnerability Areas for nitrate leaching, the INMP must be certified.  These plans are kept on the farm.
