Senators Chuck Grassley (R-IA), Tim Johnson (D-SD), Mike Enzi (R-WY) and Sherrod Brown (D-OH) have introduced the “Farm Program Integrity Act of 2013,” which would place a hard cap on the farm payments an individual farmer can receive in a year.  The legislation would establish a per farm cap of $50,000 on all commodity program benefits, except those associated with the marketing loan program (loan deficiency payments and marketing loan gains), which would be capped at $75,000.  The combined limit would be $125,000, or, for married couples, $250,000.  The $50,000 cap would apply to whatever type of program is developed as part of the new farm bill.  The bill also would close loopholes that allow non-farmers to qualify for federal farm payments.  The 2012 Senate-passed farm bill contained similar language regarding farm payments.
