You may have missed it but tucked away on BOPRC’s website is some big news from their air quality monitors that were installed in Mount Maunganui at the end of last year. The new monitors have recorded seven breaches of the national environmental standards (NES) for air quality since November 2018.
In November there was one (permitted) exceedance, and in December two breaches, of the 24-hour NES for PM10 (50 µg/m3) recorded at Whareroa Marae (location below).
In January 2019 there was also a breach of the NES for PM10 measured at the De Havilland Way monitoring site. There were a further two breaches in February (De Havilland Way and Rail Yard South) and a breach in March (Rail Yard South).
These breaches of the NES for PM10 all appeared to arise from industrial sites.
In January 2019, four (permitted) exceedances of the lower limit, 1-hour NES for SO2 (350 µg/m3) and one breach of the upper limit (not to be exceeded) 1-hour NES for SO2 (570 µg/m3) were measured at the Rata Street monitoring site.
These short-term, elevated concentrations SO2 all appeared to arise from cruise ships at the Port.
