Air

Air quality is at the top of everyone’s environmental list today. Charleston is fortunate to have good air quality that is getting better with each passing year. SC Ports is focused on improving air quality and has committed to implementing a variety of emissions-reducing programs. SC Ports’ emissions inventories and air monitoring efforts allow us to track our efforts over time and identify the emissions reductions measures that make the most sense.

In an effort to stay engaged in the well-being of our communities, SC Ports participates in numerous air working groups, including the SC Department of Health and Environmental Control, North Charleston Air Monitoring Workgroup and the Berkeley Charleston Dorchester Council of Governments Air Quality Coalition.

Clean Truck Program – By requiring trucks to have post-1993 engines, the program ensures that a reliable, cleaner trucking fleet will serve SC Ports container terminals in order to continue reducing port-related air emissions.

Air Monitoring Results – Hugh Leatherman Terminal

The Hugh Leatherman Terminal (HLT) air monitoring station was placed into operation in February of 2021. The station is located on terminal and was cited in partnership with external stakeholders. The SCDHEC approved the Quality Assurance Project Plan, which may be updated periodically to reflect improvements to the basic operating procedures or to document changes in the air quality standards. The station provides air quality data to SCPA and neighbors. Specifically, the station measures PM2.5, NO, NO2, NOx, and SO2 consistent with USEPA methodologies.

Air Monitoring Results – Wando Welch Terminal

The Wando Welch Terminal (WWT) air monitoring station was in operation from May of 2011 through September of 2020. Over that period, the station has provided air quality data to SC Ports and its neighbors and has exceeded its data completeness targets.  The station measured air quality parameters including particulate matter of 2.5 microns or less (PM2.5), nitrogen dioxide (NO2), and sulfur dioxide (SO2). The station also measured meteorological parameters such as wind speed, wind direction, temperature, relative humidity, and barometric pressure. In early 2021, the station was relocated to SC Ports’ Hugh K. Leatherman Terminal (HLT) in North Charleston where data collection started in March 2021.  In coordination with EPA and SCDHEC, SC Ports commissioned a study on the history of the WWT air monitoring station, a summary of comparisons to National Ambient Air Quality Standards (NAAQS), and an evaluation of the parameters that may have influenced or otherwise affected PM2.5, NO2, and SO2 values throughout the monitoring period. The concentrations measured by the monitoring station were underneath their respective primary and secondary NAAQS criteria throughout the entire duration of the monitoring period at WWT.

Inland Port Emissions Calculator – The Inland Port Emissions Calculator allows SC Ports customers to evaluate the emissions implications of utilizing the SC Inland Port. To date, SC Ports customers have seen a 50-90% reduction in emissions when using Inland Ports. For more information about the calculator, please contact Mark Messersmith, Permitting Manager, at (843) 375-3102 or MMessersmith@scspa.com.

Air Quality Coalitions – SC Ports is an active participant in local air quality coalitions in the communities in which we operate marine terminals. Each of the below air quality coalitions is focused on keeping their area in attainment for air quality standards:

Tri County Coalition

Waccamaw Coalition

Upstate Coalition

Diesel Emission Reduction Efforts – SC Ports has partnered with SC Department of Health and Environmental Control and was awarded $1.8 million through the Diesel Emission Reduction Act grant program to repower 12 rubber-tired gantry cranes with hybrid systems that would minimize emission of HC, CO, NOx, and PM by 98% or better and SO2 by around 84%. The equipment operates at the Wando Welch Terminal. This project is expected to be complete in 2022.
