* MEETING RICE-NESHAP REQUIREMENTS

(Reciprocating Internal Combustion Engines National Environmental Standards for Hazardous Air Particles)

EPA requires that each Catalyst have a CPMS (Continuous Parameter Monitoring System) that monitors the inlet temperature and differential pressure of the catalyst.  Catalyst inlet temperature must be maintained between 750°F and 1250°F. Compliance is based on 4-hour rolling averages(measured every 15 minutes). Pressure drop across the catalyst must not change by more than 2 inches water column at 100% load ±10% from the pressure drop measured during the initial performance test (measured once per month).
