Sec. 382.057.  EXEMPTION.  (a)  Consistent with Section 382.0511, the commission by rule may exempt from the requirements of Section 382.0518 changes within any facility if it is found on investigation that such changes will not make a significant contribution of air contaminants to the atmosphere.  The commission by rule shall exempt from the requirements of Section 382.0518 or issue a standard permit for the installation of emission control equipment that constitutes a modification or a new facility, subject to such conditions restricting the applicability of such exemption or standard permit that the commission deems necessary to accomplish the intent of this chapter.  The commission may not exempt any modification of an existing facility defined as "major" under any applicable preconstruction permitting requirements of the federal Clean Air Act or regulations adopted under that Act.  Nothing in this subsection shall be construed to limit the commission's general power to control the state's air quality under Section 382.011(a).
(b)  The commission shall adopt rules specifically defining the terms and conditions for an exemption under this section in a nonattainment area as defined by Title I of the federal Clean Air Act (42 U.S.C. Section 7401 et seq.).
