material capacity of 2,500 kilograms,
(ii) a 3,000 kilograms per hour continuous low temperature cooker;
(c) Rendering in a small, existing, low-temperature cooker for fish meal processing;
(d) Blood drying in a diesel-fired rotary drier having an output of up to 350 kg dried
blood per hour;

(ii) Auxiliary bio-filter approximately 8.2 metres by 16 metres in size.
(i)
Collection and treatment of wastewater in two anaerobic ponds (10,000 cubic metres
and 20,000 cubic metres capacity), an extended aeration system and a wastewater
settlement tank.
Rendering Plant
3.
(a) Only fresh or suitably preserved raw material shall be processed in the rendering
plant. For the purposes for this condition, "fresh" means not older than 24 hours
from the time of slaughter and "suitably preserved" means preserved by acid
stabilisation within six hours from the time of slaughter.
(b) Raw material for rendering shall not be held on-site for more than 24 hours prior to
rendering.
4.
Material shall not be left in an uncooked condition or partially cooked condition
overnight in the rendering process line.
5.
The air within the rendering plant building shall be maintained at negative pressure at all
times during processing such that all ventilation air is discharged via the bio-filter, as
described in the application for resource consent dated 21 August 2015.
6.
Spare parts for the bio-filter fan, cooker seals/valves and other equipment critical to
maintaining effective odour control shall be held on-site at all times, to minimise the time
taken to repair equipment malfunctions.
7.
Processing areas, collection sumps and traps serving the meat processing plant and
rendering plant shall be cleaned at least daily to minimise odour emissions.

8.
Raw material shall only be received within an enclosed building in order to minimise
odorous emissions.
Bio-filter 9.
(a) The bio-filter shall have an airflow loading rate of no more than 20 cubic metres of
air per hour per cubicmetre of media material;
(b) The bio-filter bed shall consist of graded bark or similar to achieve optimal odour
treatment;
(c) The bio-filter bed surface shall be maintained in a moist state using a surface
irrigation system consisting of perforated irrigation tubes;

(e) The maximum temperature of inlet air to the bio-filter shall not exceed 45 degrees
Celsius.

mat shall cover the whole of each pond surface and shall be of a thickness and integrity
that will cause it to act as an effective filter for odorous emissions.

(a) Continuous monitoring of the inlet airflow temperature to the bio-filter, including
continuous temperature visual display and manual recording of the average and
maximum temperature once each day;
