Funds appropriated to carry out section 1753 of this title during any fiscal year shall be available for payment to the States for disbursement by State educational agencies in accordance with such agreements, not inconsistent with the provisions of this chapter, as may be entered into by the Secretary and such State educational agencies for the purpose of assisting schools within the States in obtaining agricultural commodities and other foods for consumption by children in furtherance of the school lunch program authorized under this chapter. For any school year, such payments shall be made to a State only if, during such school year, the amount of the State revenues (excluding State revenues derived from the operation of the program) appropriated or used specifically for program purposes (other than any State revenues expended for salaries and administrative expenses of the program at the State level) is not less than 30 percent of the funds made available to such State under section 1753 of this title for the school year beginning July 1, 1980.

If, for any school year, the per capita income of a State is less than the average per capita income of all the States, the amount required to be expended by a State under paragraph (1) for such year shall be an amount bearing the same ratio to the amount equal to 30 percent of the funds made available to such State under section 1753 of this title for the school year beginning July 1, 1980, as the per capita income of such State bears to the average per capita income of all the States.
