(15) “Emission” means a release of air contaminants into the atmosphere.

(17) “Emission reduction option” means:
(a) An offsetting of greater emissions from a stationary source against lower emissions from the same or another stationary source.
(b) A reduction in emissions from a stationary source which is reserved as a credit against future emissions from the same or another stationary source.

This term includes, but is not limited to, substances which are toxic, corrosive, flammable, irritants, strong sensitizers or explosives as determined by the department.
