There were no adverse effects on the environment resulting from the exercise of the air discharge consents.
The ambient air quality monitoring at the production station showed that levels of carbon monoxide,
combustible gases, PM10 particulates, and nitrogen oxides were all below levels of concern at the time of
sampling. No offensive or objectionable odours were detected beyond the boundary during inspections.

There is a settling pond (Silt Pond) located on the Motukawa Race, approximately 280 m from the
Manganui River intake. The Silt Pond was constructed prior to 1950 (based on historic aerial
imagery), to reduce the amount of fine-grained sediment entering Motukawa Race and ultimately

Receiving water monitoring results for the year were generally in line with historical ranges. However, as
occasionally noted in recent years, the results at the top of the catchment for some parameters (suspended
solids, turbidity, biological oxygen demand and dissolved reactive phosphorus) were elevated when
compared to sites sampled within and below the industrial area.
