When granting new designations and land-use consents, territorial authorities and/or requiring authorities should consider the National Environmental Standards for Air Quality. This Good Practice Guide for Assessing Discharges to Air from Land Transport provides comprehensive guidance on how to consider air quality impacts from transport development.
The guide promotes a three-tiered approach to separate the simple from the complex and covers all elements of environmental assessment - not just those pollutants included in the Standards. It makes recommendations for the assessment approach to be adopted, while recognising the wide range of potential users − from planning professionals and technical experts, to council staff and hearing commissioners.
This guide replaces the draft guide issued for consultation in June 2006.
