Calls to the Pollution Hotline are logged as environment incidents. The incidents are classified as minor incidents, resource consent incidents and serious environmental incidents/alleged offences. Based on the classification, as decision is made within 30 minutes on the appropriate response for each incident reported.
Minor incidents – reported incident has not, or is not likely to, result in a significant environmental effect or offence.
Resource consent incidents – reported incident relates to an activity authorised by resource consent.
Serious environmental incidents/alleged offences – an enforcement officer investigates incidents in this category, generally through a site visit. The first priority will be to minimise any adverse effects on the environment and then to investigate the incident.

Air
Air quality incidents reported to Environment Canterbury’s Pollution Hotline most commonly relate to agricultural or industrial odour as well as smoke from domestic and outdoor fires. However, air quality incidents reported also relate to a wide range of other issues such as dust from construction sites or quarries, particulates from abrasive blasting, and other emissions from industrial premises.
Seventy three percent of the complaints received by the pollution hotline this month were related to air quality (1192 complaints). Christchurch City had the highest number of complaints (907 complaints) which is due to Environment Canterbury enforcing the air plan rules relating to domestic chimneys.

Discharges of effluent and sediments to water are commonly reported to the Environment Canterbury Pollution Hotline. Water quality incidents reported also include discharges of industrial contaminants, fish kills and works in waterways such as gravel excavation, bridge and culvert construction.
