During any year in which there is no set-aside or diversion of acreage under this subchapter, the Secretary may formulate and administer a program for the production, subject to such terms and conditions as the Secretary may prescribe, of commodities for conversion into industrial hydrocarbons and blending with gasoline or other fossil fuels for use as motor or industrial fuel, if the Secretary determines that such production is desirable in order to provide an adequate supply of commodities for such purpose, is not likely to increase the cost of the price support programs, and will not adversely affect farm income. Under the program, producers of wheat, feed grains, upland cotton, and rice shall be paid incentive payments to devote a portion of their acreage to the production of commodities for conversion into industrial hydrocarbons and blending with gasoline or other fossil fuels for use as motor or industrial fuel.

The payments under this subsection shall be at such rate or rates as the Secretary determines to be fair and reasonable, taking into consideration the participation necessary to ensure an adequate supply of the agricultural commodities for conversion into industrial hydrocarbons and blending with gasoline or other fossil fuels for use as motor or industrial fuels.

The Secretary may issue such regulations as the Secretary deems necessary to carry out the provisions of this subsection.

There are authorized to be appropriated such sums as may be necessary to carry out the provisions of this subsection.

The provisions of this subsection shall become effective October 1, 1978.
