Air quality monitoring information is often used in detailed assessments of the effects of state highway projects. In some cases, suitable data may already be available from regional councils, the Transport Agency or research organisations. However, a dedicated monitoring campaign may be required for high risk, large projects in locations with a high degree of sensitivity to adverse air quality effects. Assessment monitoring may be required early in a project’s life – pre-project monitoring – but can sometimes be required following project completion – post-project monitoring.
In addition, dust monitoring may be required during construction to support the management of any potential adverse effects. Occasionally, odour monitoring may also be required, especially if the project is being undertaken in a contaminated area.
The Transport Agency has developed a leaflet highlighting key issues that need to be considered for any monitoring campaign. Guidance on monitoring methods is available from the Ministry for the Environment as below.
