approximately 3.6 km along Palmer Road (from
the south), approximately 6 km from Kaponga.
The initial establishment of the wellsite would have involved the removal of topsoil
to create a firm level platform on which to erect a drilling rig and house associated
equipment. Site establishment also involved the installation of:
• Wastewater control, treatment and disposal facilities;
• A system to collect and control stormwater and contaminants;
• Gas combustion system; and
• Other on
formation. Once in the formation these gels ‘break’ back with time
and temperature to a liquid state and are flowed back to surface without disturbing the
proppant wedge. With continued flow, fluids pumped as part of hydraulic fracturing
process, formation fluids and hydrocarbons are drawn to the surface.
1.2.2 Kowhai-B wellsite history
The Kowhai-B wellsite has been in operation since 2012. The area around the wellsite
and Ngatimaru Road is rural with low population density. The site lies
low-lying
coast from Pātea Beach to the southern extent of the region. Cliff-top dunes are also a
unique feature of the Taranaki coastline.
The coastline is noted for high quality surf breaks. This is particularly evident along the
stretch of coast from Kaihihi Road to Stent Road, where finger like lahar deposits form
offshore reef systems, creating a high concentration of quality surf breaks.

about seven metres of the excavated soil. The volume of chemical
residue was a few litres of caked crystalline material.
The District Council immediately removed the drum remnants, the chemical residue and
approximately 80 m3 of excavated soil and rubbish to the Colson Road Regional landfill,
which is a secure landfill operated by the District Council. The excavation site was
secured while the samples were analysed by AssureQuality for chlorophenols, a multi-
residue screen

pores inhibiting hydrocarbon recovery. Nitrogen gas achieves the same purpose as water
but returns more easily to the surface.2 More indirectly, a reduction in the volume of water used also
reduces the total concentration of chemical additives required and the volume of water returning to the
surface that requires subsequent disposal.2

The Mangahewa-C wellsite is located on Tikorangi Road East, Tikorangi and lies within the

2.1.1 Marine ecological diversity and health
The Council undertakes a number of programmes that monitor marine ecological
quality, beach bathing water quality and shellfish tissue monitoring. The monitoring
confirms that Taranaki’s excellent coastal water quality has remained relatively
stable.
Marine ecological diversity or ‘health’ is monitored at six rocky shore sites. Four of
these sites (Turangi Road, Manihi Road, Greenwood Road and Waihi Reef) are

Everett Road bridge and riparian planting had been
undertaken. This vegetation was well established at the time of the 2015-2016 period.
Streambank length in the Kurapete catchment equates to 88 km. Currently, 65 km of
banks are protected by existing and completed fencing with 35 km protected by
existing/completed vegetation. Since the preparation of riparian plans, 28 km of
fencing and 12 km of planting have been completed in the catchment.
