The Maryland Port Administration (MPA) was the first port to install diesel oxidation catalysts (DOCs) on ship-to-shore (STS) and rubber-tired gantry (RTG) cranes, and this project involved the first installation of DOCs on MPA cranes.  MPA's primary goal in installing the DOCs was to decrease the particulate matter (PM), volatile organic compounds (VOCs) and carbon monoxide (CO) emitted by the two cranes involved in the demonstration.  It was critical to MPA that the DOCs have no adverse effect on the cranes, either by damaging the cranes or by impairing the crane operations.    RubberTiredGanrtyCrane POB

   This demonstration project highlighted the emission reduction capability of DOCs on port cargo-handling equipment and addressed potential installation and operational barriers.  Based on the success of this demonstration, MPA applied for and was awarded a Recovery Act grant that included funding for additional cargo-handling equipment retrofits.

 Total cost: $24,889 ($12,500 grant funded)
