PM 10 has a wide range of negative effects on human health and these are wellestablished across a range of research disciplines. PM 10 is emitted from a wide rangeof diffuse sources, including domestic fires (the primary contributor within the <strong>Waikato</strong>region), vehicle emissions, outdoor burning and industrial activities.Poor air quality has a negative impact on public health (including restricted activity daysand premature death in some individuals). As a consequence, there are associatedsocial and <strong>economic</strong> impacts, and the costs of these are borne by individuals as well asat local, <strong>regional</strong> and national levels.There are four airsheds (Tokoroa, Taupō, Te Kuiti and Putaruru) in the region withPM 10 exceedances that are of concern. Tokoroa is the key airshed to address withinthe region to improve air quality. In order to ensure that Tokoroa is compliant within theResource Management (National Environmental Standards Relating to Certain AirPollutants, Dioxins and other Toxics) Regulations 2004 timeframes, a significantinvestment of effort and resources is required. This is not only because of the highnumber of PM 10 exceedances, but also because the majority of the population lives inhighly deprived areas. 340The Resource Management (National Environmental Standards Relating to Certain AirPollutants, Dioxins and other Toxics) Regulations 2004 were amended in 2011 andrequire offsets from new industries with significant PM 10 discharges in polluted airshedsfrom September 2012. This means that new industries will only be permitted todischarge PM 10 if they reduce emissions from elsewhere so that overall emissions inthe airshed stay the same (or improve).6.9 Natural hazardsPlate tectonics make New Zealand prone to natural hazards. The <strong>Waikato</strong> CivilDefence Emergency Management Group Plan identifies the following natural hazardsfor the region: Earthquake. The area between Taupō and Rotorua is the most vulnerable in theregion. High risk of these occurring over millennia. Volcanic. Various sources within and outside the region. High risk of theseevents occurring over decades to centuries. Tsunami. These could affect both the east and west coasts. Very high risk oftsunami occurring over centuries. River flooding. The most frequent and widespread hazard. Moderate risk ofmajor flooding occurring over centuries.Severe storms. These tend to impact Thames Valley and low-lying areas themost. High risk of these occurring over decades. Drought. Hauraki Plains, lower <strong>Waikato</strong> Basin, Thames-Coromandel Districtand Pukekohe areas typically the most affected. Moderate risk of severedrought over decades. Landslides. Hipaua landslide at the south-western edge of Lake Taupō anddebris flow hazards along the western side of the Coromandel and KaimaiRanges are significant hazards. Moderate risk of large scale landslide overcenturies. 341340Banks (2011, p. 1).341<strong>Waikato</strong> Civil Defence Emergency Management Group (2011, p. 15).Doc # 2069885 Page 99
