Two resource consents for the same discharge? How does that work?


The Port of Tauranga has 115 hectares of land at Mount Maunganui which includes land currently used for wharf activities and the surrounding land used by industries supporting the Port. It is located on the eastern edge of Te Awanui (Tauranga Harbour) in the heart of Tauranga's Mount Industrial sub-catchment.

In 2017, after a long period of consultation with potential affected parties the Port applied for a stormwater discharge consent with Bay of Plenty Regional Council for:

  • The discharge of stormwater to the coastal marine area (private stormwater network and overland flow)

  • The discharge of stormwater to land  where it may enter water (Tauranga City Councils piped network)

Tauranga City Council was granted a comprehensive stormwater discharge consent in 2012, which included the Mount Industrial sub-catchment. The consent included conditions around stormwater discharge, and receiving environment quality parameters. A number of the discharges from this sub-catchment contain discharges from the Port of Tauranga.

During the Ports application process it became apparent that there were issues around how the two consents would operate together with the Port seeking differing discharge limits than that contained within TCC's comprehensive consent resulting in inconsistencies, potential compliance issues and a liability issue for TCC that all parties agreed existed, but proved difficult to solve.

The talk will discuss TCC's approach, implications at each step, and learning's from the experience.
