the tractor up
to the pond. If the tractor slopes back too far, lubricating oil in the tractor engine will fall
away from the front crank bearing, damaging the engine.
When using contractors or hiring equipment, make sure that the equipment used has been
cleaned before use on your farm. This is so diseases are not transferred within the effluent
from one property to another.
There are two types of contracting operations - pump spreaders and vehicle spreaders
(honey wagons). It is the

2.1.1 Inspections
07 December 2020
An inspection was undertaken to assess compliance with resource consent conditions. It was raining at the
time of the inspection. Four samples were obtained; one downstream (clear), one upstream (clear), one from
the storm water discharge pipe (turbid) and one form the head waters adjacent to the storm water
discharge pipe, at this location there was a visible sheen. The

lakes in the region are small lakes classified as having an open water
area of between one and five hectares. Only two lakes are recorded as having an open water area of
greater than 30 hectares.
13. In addition, there are a number of lakes in the region with an open water area of less than one hectare
which are not identified by FENZ, but still fall within the broad definition of ‘lake’ under the RMA.5 These
water bodies are more likely to be classified as wetlands rather than
the later (eastern) portions.
The most significant structures/components within the Race and lake are summarised within
Table 2 and are discussed further as follows.

stream was turbid and brown in colour. The piggery wastewater flow rate from the final pond was
estimated to be at 14 L/s.
The wastewater discharge from the final pond had no visual downstream environmental impact on the
Waiongana Stream at the time of the survey. The consent holder continued to discharge for a
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

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 Section 14.

It is possible that flaring may occur during the following activities:
• Well testing and clean-up;
• Production testing;
• Emergencies; and
• Maintenance and enhancement activities (well workovers).
