Saving Workers by Eliminating Economic Tampering and Ensuring Reliability Act or the SWEETER Act This bill eliminates certain Department of Agriculture (USDA) sugar subsidy programs. Specifically, the bill eliminates (1) the price support loan program available to processors of domestically grown sugarcane and sugar beets; (2) the sugar marketing allotments and tariff-rate quotas that limit the quantities of domestically produced sugar that processors may sell and the sugar that may be imported under lower tariff rates; and (3) the feedstock flexibility program for bioenergy producers, which operates to avoid loan forfeitures to the USDA's Commodity Credit Corporation by requiring USDA to purchase surplus sugar from domestic processors for resale to bioenergy producers.
