The Maryland Port Administration has supported dray truck replacements and retrofits since 2009.  The goal of the program is to reduce air pollution and greenhouse gases associated with the transport of goods to and from the Port of Baltimore.  


The program requires older trucks to be scrapped and provides applicants up to $30,000 toward the purchase of a newer vehicle with an engine that is model year 2010 or later.
