Consent No: 202925
(Note: Pursuant to Sections 123 and 124 of the Resource Management Act 1991, a new consent wil be
required at the expiration of this consent. The application wil be considered in accordance with the plans in
ef ect at that time, and the adverse ef ects of the proposed activity).
2. The discharge shall only be contaminants from a rendering plant processing up to 5,000 kg
of raw material per hour, collection and treatment of wastewater from rendering and meat
processing and dairy processing, a coal-fired boiler having a net heat output of up to 4
megawatts, and associated processes as described in the application for consent. These
associated processes include the combustion of wastewater treatment gases in either a flare
or boiler.
3. (a) Only fresh raw material, or material appropriately stabilised in a fresh condition, shall
be processed in the rendering plant.
(b) Raw material for rendering shall not be held on-site for more than 24 hours.
(c) No fish waste or fish by-products shall be processed in the rendering plant.
4. 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 a bio-filter, as
described in the application.
5. The bio-filter shall be capable of treating at least 10 air changes per hour from the
rendering plant, shall have a media bed depth of at least 1.2 m and shall have a design
loading of at least 80 m3 air/m2 filter surface area/hour. Design plans for the bio-filter
shall be provided to the Southland Regional Council’s Compliance Manager for approval,
prior to construction.
6. Processing areas, collection sumps and traps serving the meat processing plant and
rendering plant shall be cleaned at least daily to minimise odour emissions.
7. A gas-tight cover shall be fitted to the anaerobic lagoon such that all gases are discharged to
either the boiler or the flare for combustion. The cover shall be maintained at all times to
ensure that no gas leakage occurs.
8. The maximum coal burning rate boiler shall not exceed 1280 kilograms of coal per hour.
9. The opacity of emissions from the chimney stack of the coal-fired boiler shall not be darker
than Ringelmann Shade 1 as described in New Zealand Standard 5201:1973 except:
(a) in the case of a cold start, for a period not exceeding 30 minutes in the first hour of
operation; and
(b) for a period not exceeding a total of four minutes in each succeeding hour of
operation.
10. (a) The discharge into air from the boiler shall occur via a stack at a height of at least 20
metres above ground level and at least 12 metres above the roof ridgeline of any
adjacent building.

(b) The discharge shall be directed vertically into air and shall not be impeded by any
obstruction above the stack which decreases the vertical efflux velocity.
11. The discharge of sulphur dioxide shall not exceed a rate of 12 kilograms per hour. The
discharge rate may be determined from the maximum burning rate and sulphur content of
the coal. The consent holder shall provide records of the coal type burned in the boiler,
including calorific value and maximum sulphur content, and calculation of the maximum
sulphur dioxide emission rate based on that information. These records shall be provided
to the Southland Regional Council’s Compliance Manager at the time of any change to the
coal type burned in the boiler, and otherwise at least once every 12 months.
12. (a) The concentration of particulate matter in combustion gas discharged from the coal-
fired boiler chimney stack shall not exceed 250 milligrams per cubic metre adjusted to
0 degrees Celsius, dry gas basis, 101.3 kilopascals, and 8 percent oxygen or 12 percent
carbon dioxide.
(b) Any measurement to confirm compliance with the particulate concentration limit
shall occur when the tested boiler is operating at greater than 75 percent of the
maximum continuous rating. The method of sampling and analysis shall comply with
ISO 9096:1992(E), and may include methods BS 6069: 1992, ASTM D3685-78,
ASTM D3685M-92, AS 4323.2-1995, US EPA Method 5, US EPA Method 17 or an
equivalent method that complies with the fundamental sampling requirements of ISO
9096:1992(E).
(c) the consent holder shall measure the emissions of particulate matter in the
combustion gas discharged from the coal-fired boiler chimney stack:
(i)
once within three to six months of commissioning of the boiler;
(ii) at two yearly intervals thereafter. After at least two tests the frequency of this
testing may be reduced with the written approval of the Southland Regional
Council’s Compliance Manager.
(d) The results of the combustion gas measurements shall be reported to the Southland
Regional Council’s Compliance Manager within 20 working days of each test being
completed.
13. The boiler stack shall be fitted with a source emission test port and safe access for testing,
to the satisfaction of the Southland Regional Council’s Compliance Manager.
14. The coal-fired boiler shall be serviced at least once every year, by a person competent in the
servicing of such appliances. This servicing shall include: ash removal; adjustment if
necessary of the fuel to air ratio to ensure compliance with condition (9); and measurement
of the percentage of carbon monoxide, carbon dioxide and oxygen in the flue gases
discharged. Service reports shall be prepared and retained, and copies shall be provided to
the Southland Regional Council’s Compliance Manager on request.
15. The flare shall be operated in accordance with the specifications described in the
application. The flare shall be fitted with a continuous ignition system including spark
igniter and back-up power supply and shall be operated to achieve a minimum combustion
efficiency of 98%.

16. The total biochemical oxygen demand (BOD) load of wastewater entering the treatment
plant for treatment shall not exceed 7,500kg/day.
17. The aerated pond shall be operated to maintain aerobic conditions at all times and minimise
odour generation. Electrically powered floating aerators having a total output of at least
180 kilowatts shall be installed and shall be operated as required to comply with this
condition.
18. (a) All sludge generated by the treatment system, including DAF float solids, that are to
be removed from the site shall be pumped directly to fully enclosed tankers for
transport to disposal. If DAF solids are further processed on-site they shall be
pumped in pipelines or otherwise transferred to processing in a manner that ensures
there will be no odour.
(b) Under no circumstances shall sludge be handled, transferred or stored in open air
such that odour may be detected beyond the site boundary.
19. The discharge of anaerobic wastewater into the aerated lagoon shall be via a submerged
inlet at all times, including during initial filling of the aerated lagoon with wastewater.
20. The discharges shall not cause objectionable or offensive odour or particulate matter
(including dust and smoke) to the extent that it causes an adverse effect beyond the
boundary of the consent holder’s property.
21. The consent holder shall prepare a site management plan and submit the plan to the
Southland Regional Council’s Compliance Manager for approval no later than three
months from the completion of the commissioning of the plant. This management plan
shall detail all actions to be taken to minimise odour and particulate matter emissions from
the plant and to ensure compliance with the conditions of this consent.
The plan shall address:
(a) bio-filter maintenance requirements;
(b) operating procedures to minimise odour and particulate matter emissions from the
rendering plant;
(c) wastewater collection and treatment, including maximum holding times; and
(d) boiler plant maintenance.
The management plan shall state the name and contact telephone number of all persons
responsible for each action described in the plan and shall be updated at least annually to
include staff changes. The plan shall be available for inspection at the consent holder’s
property at all times.
22. The consent holder shall maintain a record of all complaints relating to odour or particulate
matter that are either received directly or notified by the Southland Regional Council. This
record shall include:
(a) the location where the odour or particulate matter was detected by the complainant;
(b) the date and time when the odour or particulate matter was detected;
(c) a description of the wind speed and wind direction when the odour or particulate
matter was detected by the complainant;
