The purpose of this legislation is to ensure that the National Capital Planning Commission and the Commission of Fine Arts receive funding even if their appropriations are not provided for in a given fiscal year. This is particularly important for maintaining their operations and responsibilities without interruption. The key provisions of the legislation establish a system for interim appropriations. If these commissions have funding in one fiscal year but do not receive it in the following year, the bill allows for necessary funds to be allocated from the U.S.
