C.R.S. § 25-7-114.6

(1) The commission shall designate by regulations those classes of minor or insignificant sources of air pollution which are exempt from the requirement for an emission notice or the payment of an emission notice filing fee because of their negligible impact upon air quality. (2) An air pollution emission notice shall be deemed to run with the land. The moneys collected pursuant to this section and sections 25-7-403 and 25-7-510 shall be remitted to the state treasurer, who shall credit the same to the stationary sources control fund created in section 25-7-114.7 and subject to the provisions of said section. (3) The general assembly shall direct the commission to adjust any fees imposed by this section so that the revenues approximate the annual appropriations to the division to carry out its duties under this subsection (3) with respect to stationary sources.
