On behalf of the New Jersey Department of Environmental Protection (NJDEP), Public Service Electric & Gas (PSE&G), PSEG Power, LLC, and Camptown Bus Lines, M. J. Bradley & Associates (MJB&A) managed a project to retrofit 44 school buses with Particulate Reactor^TM high performance diesel oxidation catalysts in Newark, New Jersey.

Environmental Solutions Worldwide Inc. (ESW) manufactured the Particulate Reactor^TM catalysts, while M.J. Bradley & Associates provided project management and evaluated performance and durability of the Particulate Reactor^TM catalysts in use. The Particulate Reactor^TM is verified by the California Air Resources Board (CARB) as a Level 2 device capable of greater than 50 percent reductions in particulate matter (PM).

Emission testing using both remote sensing technology (ACCUSCAN 4000^TM RSD, manufactured by Environmental Systems Products) and portable emission monitoring system technology (SEMTECH-D^TM, manufactured by Sensors, Inc.) demonstrated that the Particulate Reactor^TM technology performed consistent with the CARB-verified performance.
