Interim rule. This interim rule implements legislative provisions to prohibit direct or indirect restrictions on the sale or marketing of fluid milk on school premises or at school-sponsored events, at any time or in any place, in schools participating in the National School Lunch Program. This rule is intended to ensure that there are no policies or procedures in place that have the effect of restricting the sale or marketing of fluid milk. In addition, we are making a nonsubstantive change by converting a section heading from a question to a statement. This is intended to conform the heading to the same style as all other section headings in the part.
