Introduction
This Introduction is not part of the Licence conditions.
DER's industry licensing role
The Department of Environment Regulation (DER) is a government department for the state of
Western Australia in the portfolio of the Minister for Environment. DER's purpose is to advise on
and implement strategies for a healthy environment for the benefit of all current and future
Western Australians.
DER has responsibilities under Part V of the Environmental Protection Act 1986 (the Act) for the
licensing of prescribed premises. Through this process DER works with the business owners,
community, consultants, industry and other representatives to prevent, control and abate pollution
and environmental harm to conserve and protect the environment. DER also monitors and audits
compliance with works approvals and licence conditions, takes enforcement action as appropriate
and develops and implements licensing and industry regulation policy.
Licence requirements
This Licence is issued under Part V of the Act. Conditions contained within the Licence relate to
the prevention, reduction or control of emissions and discharges to the environment and to the
monitoring and reporting of them.
Where other statutory instruments impose obligations on the Premises/Licensee the intention is
not to replicate them in the licence conditions. You should therefore ensure that you are aware of
all your statutory obligations under the Act and any other statutory instrument. Legislation can be
accessed through the State Law Publisher website using the following link:
http://wvvw.s1 wa. qov. au/leo is lation/statutes. nsf/defau It. htm I
For your Premises relevant statutory instruments include but are not limited to obligations under
the:
• Environmental Protection (Unauthorised Discharges) Regulations 2004 — these Regulations
make it an offence to discharge certain materials such as contaminated stormwater into the
environment other than in the circumstances set out in the Regulations.
• Environmental Protection (Controlled Waste) Regulations 2004 - these Regulations place
obligations on you if you produce, accept, transport or dispose of controlled waste.
• Environmental Protection (Noise) Regulations 1997— these Regulations require noise
emissions from the Premises to comply with the assigned noise levels set out in the
Regulations.

Government of Western Australia
Department of Environment Regulation
You must comply with your licence. Non-compliance with your licence is an offence and strict
penalties exist for those who do not comply.
Licence holders are also reminded of the requirements of section 53 of the Act which places
restrictions on making certain changes to prescribed premises unless the changes are in
accordance with a works approval, licence, closure notice or environmental protection notice.
Licence fees
If you have a licence that is issued for more than one year, you are required to pay an annual
licence fee prior to the anniversary date of issue of your licence. Non payment of annual licence
fees will result in your licence ceasing to have effect meaning that it will no longer be valid and
you will need to apply for a new licence for your Premises.
Ministerial conditions
If your Premises has been assessed under Part IV of the Act you may have had conditions
imposed by the Minister for Environment. You are required to comply with any conditions
imposed by the Minister.
Premises description and Licence summary
Kwinana power station (KPS) is located in an area zoned as "general industry" under the Town of
Kwinana's Town Planning Scheme No. 2. Cockburn Sound, which is subject to the State
Environmental (Cockburn Sound) Policy 2005, is located to the west of the Premises and Alcoa's
Kwinana Alumina Refinery is located to the north. Other surrounding land uses include heavy
industry and the Kwinana industrial area. The nearest residential area is located approximately
1km east and the Naval Base Holiday Village is located approximately 2km north of KPS.
KPS is a mid merit power station and as such rarely runs at full capacity outside the summer peak
period between November and March. KPS emits emissions to air via five discharge stacks;
Stage A, Stage C, Gas Turbine KWGT1, and HEGTs KWGT2 and KWGT3. Boiler Units 1 and 2
feed the Stage A stack, Boiler Units 5 and 6 feed the Stage C stack and the Gas Turbines each
have a single source emission point. Stage A, the oldest part of KPS, was put on Care and
Maintenance in October 2011 and was decommissioned in 2013. Stage C- Unit 5 was shut down
on 30 June 2014 and Unit 6 is scheduled to be decommissioned in April 2015. There are 7
electricity generating units at KPS. Each unit's electricity generating and fuel burning capabilities
are detailed below. Each stage is serviced by one exhaust stack.
Production design capacities of different units at Kwinana Power Station
UNIT CAPACITY (MWe) FUEL
Stage A —Unit 1 120 Coal, or Gas
Stage A — Unit 2 120 Coal, or Gas
Stage C — Unit 5 200 Coal, Gas or Low sulfur distillate
Stage C — Unit 6 200 Coal, Gas or Low sulfur distillate
KWGT1 - Gas Turbine 20 Gas or Low sulfur distillate
KWGT2 — HEGT1 100 Gas or Ultra Low sulfur distillate
KWGT3 — HEGT2 100 Gas or Ultra Low sulfur distillate
Main air emissions from operation of the power station include nitrogen oxides, sulfur dioxide and
particulates. Each coal-fired boiler at KPS has two electrostatic precipitators (ESPs) followed by
an optical density (opacity) meter. The fly ash accumulated on ESP plates is removed, slurried
and pumped off site through a pipeline to Perron Quarry, which holds licence L4193/1989/11.
KPS has an ISO 14001 certified Environmental Management System.
KPS is located within the area regulated under the Environmental Protection (Kwinana)
(Atmospheric Wastes) Regulations 1992 and the Environmental Protection (Kwinana)
(Atmospheric Waste) Policy 1999 (EPP). The EPP prescribes stack SO2 emission limit for the
KPS. Synergy is also required to undertake ambient air monitoring as per the requirements of the
EPP.
