The operation of the boilers shall comply with the following:
(a) The stack heights of the 4MW Triway boilers shall be not less than 12 metres above
ground level.
(b) The opacity of smoke discharged from any boiler chimney shall not exceed
Ringelmann 1 for a chimney not fitted with a photoelectric measuring device, or 40%
for a chimney fitted with a photoelectric measuring device, except:
for 60 minutes when lighting a boiler up from cold; and thereafter
for periods not exceeding two minutes at a time and not exceeding an
aggregate of four minutes in any period of 60 minutes.
(c) Coal and ash shall be stored under cover so that there are no visible emissions of

request.
(iii) In the event that wood waste sourced from off-site is burned in the boiler, the
consent holder shall record the original source of the wood waste and obtain
signed certification from the supplier that the wood waste has not been
contaminated with any chemicals, including treatments, paints or glues. This
certification shall be held by the consent holder and shall be provided to
Environment Southland on request.
(e) The exit velocity from the chimneys shall be not less than 8 m/sec at 80% of the

times. They shall be inspected at least once annually, and any holes, or other wear
and tear, likely to affect the performance of the entrapment facilities shall be made
good immediately.

at any one time.
(j)
The wood waste burning rate in the Heatpac boiler shall not exceed 4100 kilograms
per hour.

The sulphur content of coal burned in the boilers shall not exceed 1.5 percent
by weight.
(ii) The quantity of supplementary coal burned in the Heatpac boiler shall not
exceed 1000 kilograms per hour.
4.
There shall not be any burning in the open on the site.
5.
Where weather and operating conditions are such that dust from any on site operations,
including stockpiling and the working of stockpiles, and vehicle movements in the yard,
may carry beyond the boundary of the consent holder’s premises, the consent holder shall
apply water or use other suitable means to control the dust emissions.
6.
The exits from materials handling and collection cyclones used in the process shall be free
of visible emissions of dust to the air.
7.
The consent holder shall adopt the best practicable option to minimise the emissions of the
greenhouse gas, carbon dioxide, from the process. The best practicable option includes, but
is not limited to:
the efficient combustion of the fuel used in the process
the efficient transfer of heat generated in the process
the recovery of any waste heat where practicable
8.
The emission of dust, steam or smoke pursuant to this consent shall not create a nuisance
to a person or persons beyond the boundary of the site.
Emission and Ambient Air Quality Limits

Timber dried in the kilns shall not be treated with any chemicals, excluding
antisapstain treatment chemicals approved in writing by Environment Southland.

Celsius.
10. The one hour average concentration of formaldehyde shal not exceed 30 g/m3 at any point
at or beyond the boundary of the site, as defined in condition 2, due to any emission made
pursuant to this consent.
11. Monthly deposition of nuisance particulates at or beyond the boundary of the site, as defined
in condition 2, shal not exceed 4 grams per square metre above background levels.

within three months of the commissioning of the timber drying kilns; and thereafter
(b) at least once every two years.
13. The consent holder shal monitor the ambient air concentrations of formaldehyde, downwind
