wellsites. Inspections were undertaken on 28 July and 31 October 2022, and
8 March and 16 May 2023. Additional monitoring was undertaken during the monitoring period in relation
to drilling at the Kapuni-J wellsite. This will be discussed in the annual drilling report.
28 July 2022
Heavy persistent rain and strong winds have proceeded the inspection. The stormwater system was working
well, with all stormwater being collected and directed for treatment prior to discharge from site. The site
undertaken on 20 February 2015 38

Two sites are monitored for ammonia. Both fall in band A, meaning ammonia is likely to have little to no
effect on all but the most sensitive species. Modelled estimates support monitoring results, with
approximately 82% of streams and

Conditions were overcast with recent rain and a moderate north-westerly wind, although the camp
ponds before land
application. The pond is stirred as effluent is sprayed onto pastures via a travelling rain gun.
There are two storage ponds on the property, pond 1 has a storage capacity of 24,500 m3, and pond 2 has a
storage capacity of 19,320 m3.
The existing piggery, ponds, and irrigation areas in relation to the property are shown in Figure 1, and Figure 2

overabundance of algae and aquatic weeds, impact on the
growth of sensitive species, or even become toxic to freshwater organisms.
For ammonia, modelling suggests that all streams fall in band A (92%) or band B (8%) (Figure 4). Ammonia
is expected to have little to no toxic effect on all but the most sensitive species.
For nitrate, around 12% of streams fall within band A and aquatic species are unlikely to experience the
effects of nitrate. The majority of streams fall into band B (88%) (Figure
