Schedule 1

Bluewaters Power Station Phase II (Assessment No. 1525)

The proposal is to construct and operate a 200 megawatt power station known as the. Bluewaters II Power Station adjacent to the proposed Bluewaters Power Station (i.e. Bluewaters I Power Station) on a site located approximately 4 kilometres north-east of Collie (Figure 1). It will be a sub-critical coal-fired base-load generation facility with a nominal generating capacity of up to 200 Megawatts. The Bluewaters I! Power Station will supplement the Bluewaters I Power Station and supply electricity via the South West Interconnected System (SWIS). Power from both power stations will be offered as an option for Western Power Corporation's Stage 2 Power Procurement Process (PPP) for the provision of an additional 300 Megawatts of base-load capacity.

The power station will comprise the following components:

• boiler and turbine power block;

• mechanical draft cooling tower;

• flue gas cleaning equipment;. and

• generator transformer switchyard.

The following components will be used by the Bluewaters II Power Station. These components will be substantially in place to suppmi the Bluewaters I Power Station:

• a 1 00 metre stack;

• ash and dust disposal plant;

• water treatment plant;

• transmission line connection to Westem Power Corporation switch yard;

• buildings for administration, stores, water, sewage treatment, and chemical storage;

• liquid fuel storage facilities (typically for start-up purposes);

• communications and control systems;

• water supplies;

• electrical supplies;

• drainage systems;

• roads and fencing; and '

• saline wastewater discharge through the existing Collie Power Station ocean outfall.

The plant layout is shown in Figure 2. A diagram which illustrates the input and output flows for the power station is shown in Figure 3.

Proposal: Bluewaters Power Station Phase II

Proponent: Griffin Power Pty Ltd.

Amendment of Schedule 1 -Key Proposal Characteristics

The changes to the proposal are listed below:

• Power generating capacity - an increase from 200 megawatts to 208 megawatts (i.e. 4% increase).

• Construction laydown areas - an increase in the size of the laydown area • Air emissions profile -changed due. to the use of an individual stack (instead

of a shared stack), increased generating capacity (4%), and the use of coal with a maximum sulphur content of 0.38%.

• Project layout- relocation of the wastewater treatment plant and re-alignment of the coal conveyor.

NOTICE OF INTERIM IMPLEMENTATION CONDITIONS

section 46A Environmental Protection Act 1986

Proposal: Bluewaters Power Station Phase II Shire of Collie Proponent: Bluewaters Power 2 Pty Ltd Proponent Address: Level 8, 225 St Georges Terrace, Perth WA 6000 Statement to which this notice relates: Statement 724 dated 24 May 2006

and Statement 804 dated 27 August 2009

Pursuant to section 46A(1) of the Environmental Protection Act 1986, and in addition to the conditions and procedures of Statement 724 dated 24 May 2006, as amended by Statement 804 dated 27 August 2009, the implementation of the above proposal is subject to the Interim Implementation Conditions set out in this Notice. These Interim Implementation Conditions are to have effect until a further statement is published under section 45(5) as applied by section 46(8) of the Environmental Protection Act 1986. 1 Metal Emissions Monitoring 1-1 The proponent shall ensure that air emissions from the proposal are minimised

and ensure that high quality and accurate data is available to model and verify ambient air quality.

1-2 Within 4 weeks of the date of this statement the proponent shall prepare and submit a Metal Emissions Monitoring Plan to the CEO. The Metal Emissions Monitoring Plan shall:

(1) describe the procedure for sampling and analysis of stack emissions of

the following pollutants: Arsenic, Cadmium, Total Chromium, Chromium

III, Chromium VI, Mercury and particulates;

(2) describe the procedures for sampling and analysis of a composite coal

sample that represents the coal used during stack sampling in 1-2(1).

The following parameters should be measured: Arsenic, Cadmium, Total

Chromium, Chromium III, Chromium VI and Mercury.

(3) detail how the data obtained in 1-2(1) and 1-2(2) will be validated through

the use of duplicate, blind, blank and reference samples.

(4) outline a method to determine the suitability and limitations of using the

CEMS particulate monitor as a surrogate for metal emissions, by

correlating data from the metal emissions sampling with data from the

CEMS particulate monitor.

(5) outline the format for reporting the data obtained.

1-3 After receiving notice in writing from the CEO that the Metal Emissions Monitoring Plan satisfies the requirements of condition 1-2, the proponent shall undertake the first round of metal emissions monitoring with 4 weeks of the written notice. Monitoring shall be repeated at monthly intervals and in accordance with the requirements of the Metal Emissions Monitoring Plan.

1-4 On completion of each monthly metal emissions monitoring the proponent shall report to the CEO on the following:

(1) completion of the metal emissions monitoring in accordance with the

Metal Emissions Monitoring Plan; and

(2) the results of the metal emissions monitoring. 1-5 The proponent shall provide the results of monitoring required by condition 1-3

to the CEO within four weeks of the monitoring and until such time when the CEO has confirmed by notice in writing that monitoring is no longer required.
