What is Rice Neshap?
It is the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Stationary Reciprocating Internal Combustion Engines (RICE). It is designed to limit the emission of toxic air pollutants from stationary reciprocating internal combustion engines.
What Engines are affected by this Rule?
The rules depend on factors including engine size and type, construction date and application (emergency or non-emergency). An emergency engine is one that is used to provide electrical power or provide mechanical work during an emergency situation. Examples would be if local utility power is interrupted or if pumps are needed during a flooding event. Interpretation of this rule is quite complex therefore we recommend seeking the assistance of an engineer to evaluate your site.
