La. Stat. tit. 45 § 804
During the 1977 regular session or any session prior thereto, the legislature, after reviewing all reports required by this Chapter, shall enact legislation and appropriate such funds as are necessary to enable local public agencies to implement systems required by the provisions of this Chapter including tariff charges in connection therewith. If the legislature fails to enact such legislation and appropriate such funds during the 1977 regular session, then the provisions of this Chapter shall become and remain inoperative until such legislation is enacted and funds appropriated. The dates specified for the implementation of a system, or the performance of any other duty, required by the provisions of this Chapter to be performed after 1977 shall be respectively postponed by the number of years elapsing between 1975 and the year in which the legislature appropriates such funds. It is the intent of the legislature that, if legislation providing necessary funds to local public agencies to carry out the requirements of this Chapter is enacted after the 1977 regular session of the legislature, then the time schedules specified in this Chapter shall be advanced by the number of years required for the legislature to subsequently appropriate such funds.
