Council (NPDC) operates a regional landfill located on Colson Road, New
Plymouth, in the Waiwhakaiho catchment. Stage 3 of the site has a design capacity of approximately
800,000 m3. Stage 3 ceased accepting waste in the 2020-2021 year and is now in the process of being
capped. There is capacity remaining within the design volume and NPDC have indicated that this may be
used for contingency disposal. Stages 1 and 2 have been closed and are fully reinstated.
This report for the period July
hydrocarbon exploration site located on Bedford
Road, within the Inglewood district, in the Waitara catchment. The site is called Ngatoro-G
wellsite. This report covers the period from October 2011 – June 2013. During this period, a
wellsite was established, drilled, and tested. The wellsite is now in production.
This report; for Greymouth Petroleum Limited describes the monitoring programme
implemented by the Taranaki Regional Council (the Council) to assess Greymouth
Petroleum Limited’s
(NGC),
operates a gas treatment plant located on Palmer Road at Kapuni, in the Kapuni catchment.
This report for the period July 2014-June 2015 describes the monitoring programme
implemented by the Taranaki Regional Council to assess the Company’s environmental
performance during the period under review, and the results and environmental effects of
the Company’s activities.
The Company holds a total of 10 resource consents, which include a total of 78 conditions
setting out the requirements
consents for a petrochemical production station
located on Upper Durham Road at Inglewood, in the Waitara catchment. The Sidewinder
Production Station processes oil and gas from the Company’s adjacent Sidewinder wellsite.

The Rimu Production Station receives oil and gas recovered from the Rimu, Kauri and Manutahi wells and
includes condensate, gas and LPG processing plants. The oil and gas are separated and treated to produce
condensate suitable for export from the site; gas suitable for export into Vector’s pipeline; and LPG suitable
for sale and export. Construction started in May 2001 and the plant was commissioned between February
and April 2002.
The Rimu Production Station is situated on Mokoia
Zealand. The purpose of this
report is firstly to assess the environmental risks with fracking, and secondly to
assess whether the policies, laws, regulations and institutions in New Zealand are
adequate for managing these risks. The following discussion has been based upon
this report.
The first known hydraulic fracturing operation was in 1989 at Petrocorp’s Kaimiro-2
gas well in Taranaki. Since then, almost all of the hydraulic fracturing that has taken
place in New Zealand has been done
compatible gas for temporary storage at the Tariki-A wellsite. The
consents include a number of special conditions which set out specific requirements the Company must
satisfy.
This report covers the results and findings of the monitoring programme implemented by the Council in
respect of the DWI consents held by the Company. This is the 11th report to be prepared by the Council to
cover the Company’s DWI discharges and their effects.

performance and compliance with their consents, while another 29%
demonstrated a good level of environmental performance and compliance with their
consents.

1.2.1 Background
The Taranaki Basin occupies an area of approximately 100,000 square kilometres and
is the most explored and commercially successful hydrocarbon producing area in
New Zealand. Oil and gas exploration and development has been on-going in the
region for nearly 150 years. Since the first well in
hydrocarbon producing area in New
Zealand. Oil and gas exploration and development has been on-going in the region for
nearly 150 years. Since the first well in 1865, over 600 exploration and production wells
have been drilled. While the majority of the basin is offshore, the majority of the
producing wells are onshore. The geology of the basin is derived from diverse episodes
of tectonic activity. The Cretaceous to Quaternary basin fill is up to 9,000 m thick in
places.
