Sundary morning, the Ministry of Environment and the Northern Health Authority extended their Road Dust Advisory for Burns Lake and Houston and included Terrace.
The advisory was issued because levels of dust, coarse particles with diametres of 10 micrometres or less, PM10, exceeded the provincial air quality objective of 50 micrograms per cubic meter, averaged over 24 hours in Burns Lake and Terrace, 63 and 52, respectively, while Houston remained near the provincial objective with a reading of 49 micrograms per cubic meter.
The PM10 readings in Smithers, as of 8:00 a.m. this morning, March 25, averaged 34.
The Ministry of Environment advised it could expand the advisory to other communities if dust concentrations increased.
