requirements and fluid type and properties, fluids may be re-used in multiple wells.
Cuttings
Cuttings are produced as the drill bit penetrates the underlying geological
formations. They are brought to the surface in the drilling fluid where they pass over
a shaker screen that separates the cuttings and drilling fluids. The drilling fluids are
recycled for reuse within the drilling process, but small
and in a good condition.

A south westerly breeze was blowing at the time of inspection. The bunded area where
the mixers were stored had been pumped out but there was still a trace of darkish
water in the bottom that will need to be pumped out before the next inspection. The
slurry collection area and runoff pit looked good with nothing escaping. The water
collection sump looked to be working well with the recovered water reused through
the plant. The site looked tidy with

Our preference: Option 1
Council prefers to refurbish existing premises because it
reuses existing resources and is the lowest-cost option.

rubbish disposal must not impact on water or air quality. Good
practice includes recycling, reuse and weekly rubbish collections.
· Recycling is the only environmentally sustainable option for hay and silage
wraps and other plastics.
· Care needs to be taken to avoid odour and seepage when burying dead stock
and other refuse in pits.
· There are restrictions on what you are able to burn.

the surface in the drilling fluid where they pass over a shaker screen that separates the cuttings and drilling
fluids. The drilling fluids are recycled for reuse within the drilling process, but small quantities of drilling
fluids remain adhered to the cuttings. The cuttings and smaller particle material from the drill fluid
treatment units drain into sumps. If sumps cannot be constructed, corrals or special bins are used. During
drilling, this material is the only continuous
soak holes or grit interceptors before discharging to the unnamed tributary of the Kahouri Stream.
Fletcher Concrete made the following upgrades to the site in the 2019-2020 period:
• Installing a wedge pit system in the aggregate yard to divert yard water to the stormwater settlement
pond to allow for treatment.
• Installing a holding tank to pump water from the stormwater sump and batching area for reuse in
concrete manufacture to reduce draw of freshwater.
