Amended Rule 1470-Requirements for Stationary Diesel-Fuel Internal Combustion and Other Compression Ignition Engines

Amended Rule 1470-Requirements for Stationary Diesel-Fuel Internal Combustion and Other Compression Ignition Engines

Note: Review Per Lead Proposed amended Rule (PAR) 1470 would adopt portions of the amendments to CARB's Airborne Toxic Control Measure (ATCM) for stationary diesel-fueled compression ignition engines. Proposed amendments primarily affect new emergency standby diesel-fueled compression ignition engines and new direct-drive emergency standby fire pump engines. PAR 1470 would revise the emission limits for nitrogen oxides (NOx) and hydrocarbon (HC) emissions for new emergency standby engines, which would eliminate the need to install after-treatment controls for NOx and HC. Proposed amendments would delay PM emission rates for emergency standby engines to January 1, 2012 and narrow the applicability of the current PM standards to those engines that are located within 100 meters of sensitive receptor. For emergency standby engines where residences or sensitive receptors are located beyond 100 meters, owners/operators would be required to demonstrate compliance with the risk levels in Rule 1401(d)(1)(A) and meet particulate matter emission rates of 0.15 gram per brake horsepower or comply with requirements for engines located within 100 meters of a sensitive receptor. ATCM requirements for new agricultural engines would also be incorporated by reference, replacing existing regulations for new agricultural engines in existing Rule 1470. ATCM requirements for in-use agricultural engines would be incorporated by reference. Other minor changes are proposed for clarity and consistency throughout the rule.
