The board of county commissioners recognizes that a substantial part of the tax base of the county is and will be based upon energy related growth. Further, the board realizes that such tax base will gradually decrease through depreciation, obsolescence, and depletion, leaving a tax base which will make it difficult to generate enough tax revenue for the carrying out of the usual and necessary governmental function of this county. Therefore, this chapter is enacted and titled the MILLARD COUNTY TAX STABILITY AND TRUST FUND ORDINANCE. (1988 Code § 3.20.010)
