5 Bay of Plenty Region

Air quality monitoring for PM₁₀ in the Bay of Plenty region commenced in December 1997 with the establishment of monitoring sites in Rotorua, Tauranga, Whakatane and Pongakawa.

5.1 Monitoring sites and methods

Details of the six ambient air quality PM₁₀ monitoring sites within the Bay of Plenty region are shown in Table 5.1. These include two traffic-monitoring sites in both Rotorua and Tauranga and one background PM₁₀ monitoring site in Pongakawa.

Area	Location	Duration	Site classification	Monitoring method
Rotorua	Pererika Street	From December 1997	Residential neighbourhood	TEOM
Rotorua	Fenton Street	December 1998 - February 1999	Traffic peak	TEOM
Tauranga	Otumoetei Road	From December 1997	Residential neighbourhood	TEOM

5.2 PM₁₀ concentrations

Figure 5.1 shows that concentrations of PM₁₀ (24-hour average) in the Bay of Plenty are typically within the good or acceptable air quality categories with concentrations occasionally reaching the alert category in Rotorua and Whakatane. These towns have each recorded one exceedence of the 24-hour average guideline value, both during 1998 (Table 5.2). With the exception of Whakatane, Table 5.2 shows the annual average PM₁₀ concentration in these Bay of Plenty towns ranges from 12 - 14 µgm^-3, falling within the acceptable and alert air quality categories. In Whakatane the annual average ranged from 13 to 19 µgm^-3 indicating some potential for annual average guideline value exceedences in this area.
