Environmental Report: Heavy-Duty Diesel Vehicle Emissions Inventory

ENVIRONMENTAL PROGRESS REPORT FOR THE PA FACILITIES AT THE PORT OF NY & NJ

The results of the Heavy-Duty Diesel Vehicle (HDDV) Emissions Inventory study has been completed. The study was undertaken in an effort to continue the Port Authority's assessment and evaluation of the air quality conditions related to maritime activities with the geographical boundaries of the US EPA's designated New York/New Jersey/Long Island non-attainment area for ozone.

Baseline emission estimates were developed for Nox, VOC, CO, PM10, PM2.5 and SO2, all known negative contributors to the ozone. Activities measured were: driving while on the port's marine terminals and idling time. Emissions for off-terminal activity were reviewed as well. This was conducted by estimating container terminal HDDVs during the drive between container terminals and origins and destinations within the designated non-attainment area, considered the first point of rest.

Results of this study, prepared by StarCrest Consulting Group, LLC, indicate that emissions from HDDVs serving the marine terminals within the Port of NY & NJ, when compared to total emissions within the non-attainment area, represent a small percentage of the total emissions. Nox, which is the diesel pollutant that contributes most strongly to the formation of ozone, was measured at less than .43 percent. Of this .43 percent, the Nox emissions was further broken down to show the on-terminal emissions portions for autohandling, warehouse and container operations, as well as HDDV off-terminal emissions from container operations. On-terminal idling and on-terminal transit emissions represent 16 percent and 3 percent respectively. The rest of the .43 percent represents off-terminal emissions. Collectively the other ozone gases were measured at between .01 to .03 percent. In particular, for Essex and Union counties, PM2.5, a known Asthma contributor, were .104 and .044 percent respectively. Results of this study were shared with the United States Environmental Protection Agency, the New York State Department of Environmental Conservation and the New Jersey Department of Environmental Protection.

The agency routinely reviews and examines emissions of vessels, on-port container handling equipment, rail and truck drayage. The next study currently being undertaken is looking at the age of trucks being used on port. The results of this study will be available this fall.
