The Resource Management Act 1991 and monitoring
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:
a. the neighbourhood or the wider community around an activity, and may include cultural and social-
economic effects;
b. physical effects on the locality, including landscape, amenity and visual effects;
c. ecosystems, including effects on plants,

The monitoring showed that the WWTP continued to perform to a high standard, with no issues noted in
plant performance or operation during inspection.
As in previous years, the monitoring indicated that the treatment system was treating the municipal
wastewater to the extent that no significant effects were noted in the receiving waters of the Tasman Sea,

The results of biological monitoring indicated that the discharge of treated stormwater and leachate
discharges from the Colson Road landfill site had not had any detrimental effect on the macroinvertebrate
communities of the Manganaha Stream. However, the results in the Puremu Stream and tributary indicate
there may be impacts in this stream. This may be a result of habitat differences between sites, or may result

between milking. Stormwater must be directed to the farm dairy effluent treatment
system during milking and washdown of the yard. This will ensure that contaminated
stormwater cannot discharge to local waterways.
Clean water from plate coolers should be reused as washdown water.
1.2 Reducing manure
Manage the herd to reduce effluent. Consider the following:
Reduce noise and herd stress - treat the stock gently before
heavy applications of nitrogen (effluent)
early in the life of the plant. Current effluent application is considerably lower than previous
application rates. However nitrate concentrations 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 and extends
from a previous leak in an effluent storage basin. This basin has since been repaired. A

A review of abstraction records showed that there were some minor non-compliances at Cold
