         2. The control measures established in subsection 1 may be replaced or supplemented with alternative technologies approved in advance by the Director, provided that the emission limits in subsection 1 are met. The established or approved control measures must be installed and operating:

         (a) For NV Energy’s Fort Churchill, Tracy and Reid Gardner generating stations:

              (1) On or before June 30, 2016; or

              (2) Not later than 5 years after approval of Nevada’s state implementation plan for regional haze by the United States Environmental Protection Agency Region 9,

    Ê whichever occurs first.

         (b) For Southern California Edison’s Mohave Generating Station, at the time that each unit resumes operation.

         3. If the ownership of any BART regulated emission unit changes, the new owner must comply with the requirements set forth in subsection 2.

         4. For purposes of this section, emissions of PM10 include the components of PM2.5 as a subset.
