in this high rainfall area is being investigated. The
requirement to discharge to land, in most cases, addresses cultural and water
quality concerns.
Recommended
That the Taranaki Regional Council:
a) receives this memorandum
b) agrees that from December 2022 consent holders applying for a consent renewal
will be required to immediately start discharging to land once their consent has
been issued
c) agrees that those consent holders whose consents are about to expire be
