During the 2014 legislative session, DEQ was funded to conduct air toxics monitoring in the Swan Island area of
DEQ will locate and operate three types of monitoring equipment on Swan Island for one year. A full spectrum air toxics monitor will measure a wide range of toxic pollutants. A particulate monitor will detect levels of metals including cadmium and arsenic at concentrations above health benchmarks. Six to eight meteorology stations will provide information about temperature, wind direction and speed to track weather conditions associated with elevated air pollution.
By collecting and analyzing additional monitoring and meteorology data, DEQ will gain a better understanding of air toxics sources and exposures and risks associated with those exposures. The data can help determine what emission reduction options might be necessary to mitigate risks from exposure to toxic pollutants in the area.
By comparing complaint and industrial facility data to wind speeds and directions, DEQ will be better able to identify air pollution sources and patterns from facilities. This will allow more informed odor investigations and responses under DEQ’s Nuisance Odor Strategy.
DEQ anticipates the monitors will be installed and collecting data sometime during fall 2014.
