Air Quality Exceedance

The Tasman District Council measures the amount of PM₁₀ (very fine particulate matter smaller than 10 microns) in the air.  The monitoring sites are located in Richmond Central (Richmond airshed) and a temporary site is located in Motueka (rest of the region airshed). The National Environmental Standard for Air Quality for PM₁₀ is 50 micrograms per cubic metre (μg/m3).      

The PM₁₀ concentrations exceeded the 24-hour concentration of 50 micrograms per cubic metre (μg/m3) on the following dates:

The total number of exceedances in Richmond for Winter 2021 was 4.

In winter, most PM₁₀ in Richmond comes from wood burning.  Burning only dry wood in a compliant woodburner can reduce PM₁₀.
