4. Environmental performance

As required by the CRL designation conditions and the A2N resource consent conditions, the purpose of this AQ DWP is to ensure that construction air quality effects are kept to a practical minimum, recognising the sensitivity of the environment within which the works are being undertaken.

The key air quality compliance requirement for construction activities is that dust and other air discharges from the activities do not result in offensive or objectionable levels of dust or other contaminants beyond the site boundary.

A range of air quality management and monitoring measures are specified in sections 5 and 6 to minimise the potential for adverse air quality effects and avoid the occurrence of offensive or objectionable dust or contaminants in the surrounding environment.

These measures include monitoring trigger levels and response actions, which are intended to provide operational feedback to improve air quality management. The monitoring trigger levels are not intended as environmental performance standards in and of themselves.
