2020 WHIP+ Reauthorization Act This bill expands disaster indemnity programs through which the Department of Agriculture provides payments to agricultural producers for crop and milk losses resulting from hurricanes, wildfires, and other qualifying natural disasters. In particular, the bill extends the Wildfire and Hurricane Indemnity Program Plus (WHIP+), the On-Farm Storage Loss Program, and the Milk Loss Program to make losses that occurred in the 2021 and 2022 calendar years eligible for payments. Under current law, these programs provide disaster payments to agricultural producers with crop and milk losses resulting from qualifying natural disasters that occurred in the 2018 and 2019 calendar years.
