(D)
(2) Effective July 1, 1999, one-third of the sulphur severance tax, but not to exceed one hundred thousand dollars; one-third of the lignite severance tax, but not to exceed one hundred thousand dollars; one-fifth of the severance tax on all natural resources, other than sulphur, lignite, or timber, but not to exceed seven hundred fifty thousand dollars; and three-fourths of the timber severance tax shall be remitted to the governing authority of the parish in which severance or production occurs.
(3) Effective July 1, 2007, one-fifth of the severance tax on all natural resources other than sulphur, lignite, or timber shall be remitted to the governing authority of the parish in which severance or production occurs. The initial maximum amount remitted to the parish in which severance or production occurs shall not exceed eight hundred fifty thousand dollars. The maximum amount remitted shall be increased each July first, beginning in 2008, by an amount equal to the average annual increase in the Consumer Price Index for all urban consumers, as published by the United States Department of Labor, for the previous calendar year, as calculated and adopted by the Revenue Estimating Conference.
(4) Effective April 1, 2012, the provisions of this Subparagraph shall be implemented if and when the last official forecast of revenues adopted for a fiscal year before the start of that fiscal year contains an estimate of severance tax revenues derived from natural resources other than sulphur, lignite, or timber in an amount which exceeds the actual severance tax revenues from such natural resources collected in Fiscal Year 2008-2009. Upon the adoption of such official forecast, the Revenue Estimating Conference shall certify that the requirements for the implementation of the provisions contained in this Subparagraph have been met. In such event, the following distributions and allocations of severance tax revenues and other revenues provided in this Subparagraph shall be effective and implemented for the fiscal year for which the official forecast was adopted, and each year thereafter. The legislature shall provide by law for the administrative procedures necessary to change the severance tax allocation to parishes from a calendar year basis to a fiscal year basis.
(ii) On July first of each year the maximum amount remitted to the parish in which severance or production occurs, as provided in Item (i) of this Subsubparagraph, shall be increased by an amount equal to the average annual increase in the Consumer Price Index for all urban consumers for the previous calendar year, as published by the United States Department of Labor, which amount shall be as calculated and adopted by the Revenue Estimating Conference.
(iii) Of the total amount of severance tax revenues remitted in a fiscal year to a parish governing authority pursuant to the provisions of this Subparagraph, any portion which is in excess of the amount of such tax revenues remitted to that parish in Fiscal Year 2011-2012 shall be known as "excess severance tax". At least fifty percent of the excess severance tax received by a parish governing authority in a fiscal year shall be expended within the parish in the same manner and for the same purposes as monies received by the parish from the Parish Transportation Fund.
