Sec.  89.106  Prohibited controls.



    (a) An engine may not be equipped with an emission control system 

for the purpose of complying with emission standards if such system will 

cause or contribute to an unreasonable risk to public health, welfare, 

or safety in its operation or function.

    (b) You may not design your engines with emission-control devices, 

systems, or elements of design that cause or contribute to an 

unreasonable risk to public health, welfare, or safety while operating. 

For example, this would apply if the engine emits a noxious or toxic 

substance it would otherwise not emit that contributes to such an 

unreasonable risk.
