### NAC 445B.22095 Emission limitation for BART. ( NRS 445B.210 ) The emission limitation for BART must be established on a case-by-case basis, taking into consideration: 1. The technology available; 2. The costs of compliance; 3. The energy and nonair quality environmental impacts of compliance; 4. Any pollution control equipment in use or in existence at the source or unit; 5. The remaining useful life of the source or unit; and 6. The degree of improvement in visibility whic h may reasonably be anticipated to result from the use of such technology. (Added to NAC by Environmental Comm’n by R190-08, eff. 4-23-2009)

### 2. The control measures established in subsec tion 1 may be replaced or s upplemented with alternative technologies approved in advance by the Director, provi ded that the emission limits in subsection 1 are met. The established or approved control m easures must be installed and operating: (a) For NV Energy’s Fort Churchill, Tracy and Reid Gardner generating stations: (1) On or before January 1, 2015; 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,

¬ 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 PM 10 

### include the components of PM 2.5 

### as a subset. (Added to NAC by Environmental Comm’n by R190-08, eff. 4-23-2009; A by R148-09, 1-28-2010)
