NAC445B.063. “Excess emissions” defined.

“Excess emissions” means any emission which exceeds any applicable emission limitation prescribed by NAC 445B.001 to 445B.3689, inclusive, or that is contained in an operating permit. The averaging time and test procedures for determining excess emissions must be as specified in the relevant condition or conditions of the operating permit, except that this does not preclude the use, including the exclusive use, of any credible evidence or information relevant to the determination of whether a source would have been in compliance with the applicable requirements if the appropriate performance or compliance test or procedure had been performed to determine excess emissions.
