There is hereby authorized to be appropriated for the fiscal year ending June 30, 1970, and for each succeeding fiscal year, such sums as may be necessary to enable the Secretary of Agriculture, under such rules and regulations as the Secretary may deem in the public interest, to encourage consumption of fluid milk by children in the United States in (A) nonprofit schools of high school grade and under, except as provided in paragraph (2), which do not participate in a meal service program authorized under this chapter or the Richard B. Russell National School Lunch Act [42 U.S.C. 1751 et seq.], and (B) nonprofit nursery schools, child-care centers, settlement houses, summer camps, and similar nonprofit institutions devoted to the care and training of children, which do not participate in a meal service program authorized under this chapter or the Richard B. Russell National School Lunch Act.

The limitation imposed under paragraph (1)(A) for participation of nonprofit schools in the special milk program shall not apply to split-session kindergarten programs conducted in schools in which children do not have access to the meal service program operating in schools the children attend as authorized under this chapter or the Richard B. Russell National School Lunch Act.
