This final rule sets forth the Commodity Credit Corporation's (CCC) policy with respect to implementation of the discretionary authority provided to it by Public Law 108-470. This act allows for the collection of assessments levied on the marketings of agricultural commodities. Generally, these assessments are required, under State and Federal law, to be paid from CCC marketing assistance loan proceeds by a producer who markets the commodity or are required to be collected by the first purchaser of the commodity. This final rule adopts, with changes, the proposed rule published in the Federal Register on June 7, 2005 (70 FR 33043).
