Okla. Stat. tit. 68 § 102.3
In addition to their other duties, the members of the Oklahoma Tax Commission shall make a continuous study of the critical national energy crisis to determine its impact on the tax revenues of Oklahoma, particularly the revenues derived from the gross production taxes and gasoline and other motor fuel taxes and also to determine and project the degree of the consequent erosion of the present tax structure of the state which will be caused by the gradual change from the use of oil and natural gas as a basic fuel for energy. The Commission shall make periodic appraisals concerning the several taxes directly related to the fuels presently used by motor vehicles and other modes of travel and for heating and cooling, as well as the tax paid by those engaged in the business of producing oil and gas, as the use of substitute types of fuels evolve which undoubtedly will result in substantial changes in the types and size of vehicles used in the business activities of many taxpayers.
The Commission shall also develop such econometric models as are deemed necessary, compile data and other information as to the possible rate of decline in tax revenue and report to the Governor, Speaker of the House of Representatives and President Pro Tempore of the Senate by the second Tuesday of every year, to insure the availability of revenue to properly operate and carry on the functions of state and local government.
For the performance of such additional duties, the members of said Commission not receiving the maximum salary provided in Section 102.1 of Title 68 of the Oklahoma Statutes shall be compensated as follows:
The Chairman of said Commission shall receive Eleven Thousand Five Hundred Dollars ($11,500.00) per annum and the Vice Chairman and Secretary-Member of said Commission shall each receive Fifteen Thousand Five Hundred Dollars ($15,500.00) per annum, payable monthly. Provided, it is the intent hereof that no member of said Commission shall receive total compensation greater than that provided in Section 102.1 of Title 68 of the Oklahoma Statutes as amended.
