Report: Charleston Port reducing air emissions

      CHARLESTON, S.C. (AP) - A new report finds that efforts by the Port of Charleston to improve air quality are paying off.

      The report released Monday compares pollutants from port-related activities in 2011 to a 2005 baseline of such pollution compiled in an earlier study.

      The report found that newer, cleaner engines for trucks and other port equipment have led to a 51% decrease in carbon monoxide and a 26% in hydrocarbons released into the air.

      The analysis was conducted by Moffat and Nichol consultants. The area they studied extends from just outside Charleston Harbor through Charleston, Dorchester and Berkeley counties.

      Last week the State Ports Authority agreed to extend a long-term agreement with the state Department of Health and Environmental Control to reduce the port's impact on air quality.
