Dear Secretary Vilsack,

We are writing you to inquire about the methodology USDA is using to determine average county yields for the Agriculture Risk Coverage (ARC) county program.  ARC is designed to protect farmers against sudden drops in revenue by offering protection to farmers based on both the county yield for a crop and the average marketing year price.  Section 1117 of the 2014 Farm Bill instructs you to determine the average yield of counties for the five most recent crop years.

Farmers have raised concerns about the yield data being utilized by USDA and the resulting distribution of payments to counties.  We recognize counties are different sizes which can affect how well the crops in a county correlate to the county average yield.  However, legitimate questions have been raised about the significant payment disparity that has occurred between adjacent counties in certain areas throughout the country.

To help us better understand how USDA determines ARC county payments, please provide answers to the following questions:

1)    What methodology does USDA use to determine county yields for the ARC program?

2)    If a significant inconsistency in county yields is determined between adjacent counties, does USDA do any further analysis to ensure the county yield numbers are correct?

3)    Does anything prevent USDA from using county yield data from the Risk Management Agency (RMA) for the determination of ARC county yields?

We look forward to working with you to ensure the farm safety net functions properly for farmers across the country.
