Ambient air quality monitoring at the Kapuni Production Station showed that levels of carbon monoxide,
particulate matter and nitrogen oxides were below levels of concern at the time of sampling. No offensive or
objectionable odours were detected beyond the boundary during inspections and there were no complaints
in relation to air emissions from the site.
For reference, in the 2023/24 year, consent holders were

The RMA primarily addresses environmental ‘effects’ which are defined as positive or adverse, temporary or
permanent, past, present or future, or cumulative. Effects may arise in relation to:

blasting or asphalt manufacturing processes. Deposited dust levels likely represent normal levels for an
industrial area.
The consents also require that the companies complete various administrative actions including maintaining
and updating air quality management plans, and in the case of Downer EDI Ltd conduct testing of emissions
from the asphalt plant.
During the year, Downer EDI Works Ltd demonstrated a high level of environmental and administrative
concentrations in shallow
groundwater. This is in part a result of heavy applications of nitrogen (effluent) early in the life of the plant.
Current effluent application is considerably lower than historic application rates. However, nitrate
concentration in the soil profile underneath the irrigation areas and in the tributaries flowing through or
adjacent to the site remain elevated.
A narrow but concentrated plume of ammonia is present in the groundwater resulting from previous leaks
