# §260.40. When are these provisions in effect?

- (a) In determining whether a State is subject to a penalty under parts [261](/cfr/45/part261.md) through [265](/cfr/45/part265.md) of this chapter, we will not apply the regulatory provisions in parts [260](/cfr/45/part260.md) through [265](/cfr/45/part265.md) of this chapter retroactively. We will judge State actions that occurred prior to the effective date of these rules and expenditures of funds received prior to the effective date only against a reasonable interpretation of the statutory provisions in title IV-A of the Act.
- (b) **The effective date of these rules is October 1, 1999.**
