Verification Procedure: Currently Verified

The following information is provided as a summary of verified diesel emission control strategies. Additional requirements specific to engine compatibility are provided in the Executive Order. The factors outlined in the Executive Order are legal requirements of each verification; therefore, these conditions must be met before determining if a particular device is applicable to the end-users type of engine. CARB recommends that you contact the manufacturer, or their authorized distributor, prior to making any purchasing decision.

Cleaire products have not been available for sale or lease since it ceased operations on January 18, 2013. ESW CleanTech Incorporated (ESW CleanTech) acquired the Cleaire product line on April 18, 2013, and will provide new sales of product under its ownership as well as support for existing Cleaire customers. Vehicles that have the Cleaire devices already installed in a verified configuration will continue to meet applicable in-use fleet rule requirements. Refer to Cleaire Information for additional information.

Although the governing CARB Executive Order (EO) DE‑14-005-07 previously covered the LTR systems for engines (model years 1996 through 2021), for engine families listed in the EO attachment, that verification is not currently up to date. This notice will remain in effect until Miratech demonstrates to CARB’s satisfaction that its LTR systems fully comply with the requirements specified in the In-Use Compliance Requirements of the Verification Procedure, Warranty, and In-Use Compliance Requirements for In-Use Strategies to Control Emissions from Diesel Engines (Verification Procedures) (Cal. Code Regs., tit. 13, § 2709). Miratech has stated that it plans to seek and complete remedial measures needed to reinstate compliance. CARB staff will work with Miratech in this regard under the process set forth in the Verification Procedures. Stationary emergency standby generators with a PM emission rate of 0.22 g/bhp-hr or less.
