N.D. Cent. Code § 23.1-08-04
Notwithstanding any other provision of law, the legislative assembly deems the present use and disposal of coal combustion residuals to be acceptable and that present regulation allows for the beneficial use of coal combustion residuals in concrete, for other construction applications, and for other innovative uses and allows for safe disposal without coal combustion residuals being regulated as a hazardous waste. For purposes of regulating coal combustion residuals, the term "ground water" means water below the land surface in a zone of saturation. If a federal law or regulation is adopted pertaining to the use and disposal of coal combustion residuals, this section does not prohibit the state from seeking state primacy of the federal program.
