the best
level of control. The technicians use weather forecasting to predict the lime dose,
for example reducing the lime does set point if heavy rain is forecast. However,
the weather forecasts have not always eventuated which sometimes results in
quadrants being under-dosed. The technicians continue to focus on pH control
to achieve target dose ranges.

Rainfall for May was generally above the long-term May average, ranging from 85% to 179%, with an average of 118% of normal. Rainfall was higher around the Maunga and Ring Plain, and in the south of the region. Year to date rainfall is sitting between 75.6% and 213.4% with an average of 121.8% of normal. Cape Egmont remains at more than 200% of normal to date and has already received 80% of a typical year’s rain in five months. May 2022 hydrology report May 2022 rainfall maps What you should
unacceptable wastes being exposed by coastal
erosion. This resulted in the site being closed to the public in 2017. Any further dune stabilisation will be
done using green waste disposed of at the Patea transfer station.
Patea Beach is an elevated site which for most of the time is dry. Rain that does fall on the site drains away
at a very rapid rate. The site does not suffer from flooding from rain or tidal action, due to its elevation.

figure of 43mm of rainfall per hour will be utilised. This is a very
consen/ative figure as values for the top 30 occurrences range from 8.0 to 15mm with the
average being 9.4mm (refer Table 2)
Runoff of the falling rain will be influenced by the site's runoff coefficient. This has been
calculated to be 0.7. Remediation (NZ) Ltd considers this coefficient to be a conservative
runoff coefficient as the papa base provides a very high degree of impermeability.

Rainfall for April was generally well below the average, ranging from 27% to 72%, with an average of 50% of normal for April. Rainfall was higher around the Maunga and ring plain, and Cape Egmont received 84% of normal rain. Most of the rain fell in two events on 6 and 22 April. Te Maunga recorded between 67% and 79% of normal. Year to date rainfall is sitting between 67% and 213% with an average of 113% of normal.

2. Results
2.1 Inspections
The site was inspected on two occasions. The inspections focussed on the type of
material being discharged, discharge site stability and leachate/stormwater control.
7 November 2012.
A site visit was made to conduct a compliance monitoring inspection. The weather
was fine with no rain falling over the previous 48 hours. There did not appear to be
any new greenwaste discharged at the site since the
to repair the shed. The front of the site was very clean. A leaf blower had been purchased
to clean the hard stand area and it was noted that this was free from debris during the inspection. Broken
pipe work had been repaired. No discharge was occurring from the treatment system. All windrows were
covered and no odour was detected on site or beyond the boundary of the property at the time of the
inspection.
17 August 2021
Very heavy rain had occurred prior to the inspection and the
site security and upkeep /
maintenance of the site in accordance with this Plan.

The operating hours of the site are generally 7:00am to 5:00pm daily but
may vary to cater for specific needs of clients1
3. 1.4 Internal roads & tracks
Internal roads and tracks are to be maintained to ensure that silt or spilt
waste does not enter the Haehanga Stream. The Site Manager to check

g) Discharge point design
Dispersion of discharges is enhanced by:
increasing the height of discharge points;
avoiding the use of conical rain shields over the
top of discharge stacks;
increasing vertical exhaust velocities by
appropriate fan speeds, fan sizes, and shaft
sizes;
the use of vertical discharge fan units with
minimal obstruction to the outside shaft’s
airflow;
