inspection of the well sites associated with the MMPS was carried out to check for compliance
with resource consent conditions. Heavy and persistent rain had fallen the previous night. Well sites
inspected were Mangahewa-A, C, D, and E; Pouri-A; Pukemai-A; Tuhua-A, B, C and D; McKee B, C, D and E;
Toetoe-A, B and C; and Mystone-A. In general, the sites were tidy and clean with minimal activity occurring.
The sites were being maintained with weed spraying evident on the site and in some places within
the final aerobic pond into the neighbouring Waiongana Stream in
compliance with the conditions of Consent 0715.

1.3 Resource consents
Water abstraction permit 1.3.1
Section 14 of the RMA stipulates that no person may take, use, dam or divert any
water, unless the activity is expressly allowed for by a resource consent or a rule in a
regional plan, or it falls within some particular categories set out in
remediation pad. Any rain run-off and leachate that is
generated, drains into a series of ponds for treatment. Between each pond there is a
baffle that skims off any floating hydrocarbons as the leachate passes through. These
ponds also treat the leachate and stormwater from pad 1 where remediated drilling
wastes are stored and/or processed further. The treated liquid from the pond
treatment system (PTS) is then irrigated to cut and carry pasture on two irrigation
areas.

bacteriological sampling at four sites at Urenui and five sites at
Onaero.
The monitoring showed that the wastewater treatment systems at the beach camps did not adversely affect
the water quality of the local freshwater and coastal environments. Although high bacteriological results
were returned from the water quality sampling efforts, these counts were attributed to surface runoff
draining the upstream agricultural catchment, following the rains that preceded the sampling.

The camp was quiet at the time of inspection with only one caravan on site. There were no odours or visual
issues near the WWTP or trenches. The sea was rough (BF3) with strong onshore winds. The WWTP
appeared to be operating in compliance with its consent conditions at the time of inspection.

The monitoring inspection was completed late this month due to heavy rain prior which may have masked
any effects from the WWTP. The camp was reasonably busy at the
rain had caused overflow to the Kurapete
Stream. The discharge had no significant visual effect downstream in the receiving waters. Samples were
collected of the discharge, upstream and two sites downstream.

The primary screen was operating and wastes were fully contained. The pond level had been lowered in the
primary lagoon to allow a survey to be carried out around the wave band perimeter (remedial works are
planned during the 22/23 summer). The pond was turbid and
sea, but these are generally few in number and only the rare spills have a major and
indeed measurable impact on seafoods in the area.
“Indirect” discharges is a term used to generally describe the effects of rivers on the
coast, and therefore include the considerable amounts of faecal bacteria, nutrients and
solids carried down the Waitara River after rain on the farms and hill country
upstream (now seen as the major source of these in local seafoods). The material and

stormwater falling on the non-process areas of the western half of the site (Figure 1) is
directed by “v” ditches running alongside the roads to a dam/pond and then out to the Tasman Sea via the
Manu Stream. Stormwater falling on the eastern side of the site is directed to unnamed tributaries of the
Waihi Stream via outfalls and a small sedimentation pond.
Sludge from the storm pond, off-spec pond and blow down pond stored in lagoons 2, 3, and 4 was
removed during 2006. The sludge in lagoon 1 is …
