75-2-203. Board to set emission levels. (1) The board may establish the limitations of the levels, concentrations, or quantities of emissions of various pollutants from any source necessary to prevent, abate, or control air pollution. Except as otherwise provided in or pursuant to this section, such levels, concentrations, or quantities shall be controlling, and no emission in excess thereof shall be lawful.
     (2) In any area where the concentration of air pollution sources or of population or where the nature of the economy or of land and its uses so require, the board may fix more stringent requirements governing the emission of air pollutants than those in effect pursuant to subsection (1) of this section.
     (3) The board may by rule use any widely recognized measuring system for measuring emission of air contaminants.
     (4) Should federal minimum standards of air pollution be set by federal law, the board may, if necessary in some localities of this state, set more stringent standards by rule.
