INTRODUCTION TO EAP, RESPONSIBILITIES & DAM DESCRIPTION
4.1 INTRODUCTION TO EMERGENCY ACTION PLAN (EAP)
4.1.1 Purpose
This Plan defines responsibilities and procedures designed to identify conditions in time to take remedial action, including those which may endanger Coolmunda Dam, and to notify the appropriate authorities, Emergency Agencies and Public Officials of possible, impending, or actual failure of the dam. The location of the dam is provided in Section 7.
The main purpose of the Plan is to ensure that timely warning is provided to the appropriate Authorities and Emergency Agencies in the event of a major incident impacting on the dam, and to provide relevant information foruse in the emergency response to the situation.
The Plan identifies emergency conditions at the dam, and describes procedures to be followed by SunWater staff to investigate those conditions and provide warning to appropriate authorities and emergency agencies, so that they can implement measures for protection of the downstream communities and properties if necessary. The Plan also provides direction to operating staff for handling unsafe or emergency conditions, so that the dam can be returned to a safe operating condition with minimal delay.
4.1.2 Classification Category
According to Queensland Dam Safety Management Guidelines 2002, Coolmunda Dam is classified with Category 2 Failure Impact Rating, having apopulation in excess of 100 people atrisk.
4.1.3 Role of Emergency Event Coordinator (EEC)
Emergency Event Coordinator (EEC) is a role created in all SunWater Business Centres. The role will be activated during an emergency event (all hours) until the emergency is over. In the event of an emergency, the EEC will implement appropriate emergency procedures for which they have been trained.
Under normal operational conditions, the Asset Engineering Manager, Service Delivery Manager or Service Delivery Coordinator/Supervisor will perform this role. During an emergency condition any personnel trained for this role can serve as the Emergency Event Coordinator.

EMERGENCY IDENTIFICATION, EVALUATION AND ACTIONS
The dam has been designed to conform to the latest accepted design standards, so that its failure is highly unlikely. In order to maintain the dam in a safe condition and detect any emergency conditions as soon as it begins to develop or becomes apparent, the following is applicable to Coolmunda Dam.
5.1 Inspections
The following inspections are conducted atCoolmunda Dam:
• Routine Visual Inspection - Conducted Weekly • Detailed Inspection - Conducted Annually • Comprehensive Inspection - Conducted Five-yearly
5.2 Instrumentation and Monitoring
To confirm the structural behaviour and safety of the embankment the following Instrumentation was installed, and ismonitored, at Coolmunda Dam.
• Water Level measurement
• Settlement I Movement measurement
The location ofinstrumentation and monitoring equipment are listed in Section 6C.
5.3 Emergency Identification
Five major possible emergencies have been identified atSunWater Dams, which are:
• Emergency Event due toextreme inflow floods overtopping the Dam. • Emergency Event due to rapid drawdown ofthe reservoir. • Emergency Event due to a rapidly deteriorating structural deficiency such as may be induced by an extreme earthquake orerosion of the foundations and abutments. (This isthe so-called "Sunny Day" failure, l.e, not induced by an inflow flood). • Emergency Event due toextreme changes in the chemical/toxic spill. • Emergency Event due to a terrorist activity.
SunWater Section 5: Page 1 of 2 Jan 08, Issue 2-0 EMERGENCY ACTION PLAN - COOLMUNDA DAM
5.4 EVALUATION OF INCIDENTS
It is considered that ACTION 1 - Localised Incident/Near Miss, is to be locally contained, with a short-term impact (generally reported in the Monthly Dam Surveillance Report). Although each emergency condition will be evaluated and responded to individually, the action of most emergencies will be similar and follow procedures outlined below.
5.4.1 Flood Operation
All flood events, at or above Full Supply Level EL 314.07 m, will require the Dam Duty Operator to inform the Emergency Event Coordinator, who will further activate the following Emergency Evaluation Procedure I ACTION 2 I
5.4.2 Imminent Dam Failure
At Coolmunda Dam, if a staff member observes evidence of an imminent dam failure, such as water flowing through a breach in the dam, he/she will inform the Dam Duty Officer and/or Emergency Event Coordinator, who will activate the following Emergency Evaluation Procedure I ACTION 3 I
5.4.3 Unsafe or Unusual Conditions
If during a routine inspection, or at any other time, an unsafe or unusual condition is detected, the Coolmunda Dam staff will immediately notify the Dam Duty Officer and/or Service Coordinator, Goondiwindi, who will advice the Principal Engineer (Dam Safety), and/or Manager (Asset Management), so that an evaluation of the situation can be carried out and a determination can be made on the condition ofthe dam.
If the Asset Engineering Manager, and/or Service Delivery Manager, following an inspection of the ~ dam, and in consultation with Principal Engineer (Dam Safety~, and/or Manager (Asset 'I' Management), determine that(P0tential for the failure of the dam exists)hen he/she will activate the W.61 .....

Scenario 1: Flood Operation
Under normal conditions, the operation of the storage is controlled by the on-site Storage Supervisor (Dam Duty Operator), on advice from the Service Coordinator (Goondiwindi).
During flood events, the dam will be continuously manned and will be controlled from the Ipswich Regional Centre. The head office at Brisbane will transmit any information received from the Bureau of Meteorology to the Ipswich Regional Centre.
The Dam Duty Officer will keep the Emergency Event Coordinator informed ofdischarge through the spillway. The Emergency Event Coordinator will(!jiform the Asset Engineerin Manager, whg w' further keep the Local Government Disaster Management Group (LGDMG) in orme of the discharge through the spillway. In particuiar, the following alerts will be sent to the District Disaster Coordinator and Counter Disaster & Rescue Services in Brisbane.
The flood emergency event will start after the storage level has reached Full Supply Level (EL 314.07 m). In all other cases, follow the Operation and Maintenance Manual and Standing Operating Procedures.

Ensure that a responsible person with portable communication isleft in a safe position atthe dam to monitor the emergency condition. 2. Restrict access to the dam area. 3. Liaise with Emergency Event Coordinator and the Asset Engineering Manager, who will liaise with Emergency Management Authorities. 4. If possible, document the emergency condition with photographs and orvideo camera. 5. Update Emergency Event Coordinator from time to time of any change in the emergency condition. 6. Do not take any unnecessary risks in undertaking the above actions. Since the most likely scenario for a dam failure at Coolmunda Dam isfrom Sunny Day Failure, the stability may be increased by using available earth and rockfill material as a stabilising berm. A list of equipment (earthmoving), and equipment supply organisations, available during an emergency, isprovided in Section 3. It may become necessary during an emergency to lower the reservoir level of the dam to decrease seepage and/or loading on the structure, and to minimise the impact of any failure. This would only be an option where an emergency condition was identified in the early stages. Instructions for operation of the outlet works are given in section 2.7 ofthe Operation and Maintenance Manual forthe dam.

This would only be an option when an emergency condition has been identified in its early stages. 8.1 Coolmunda Dam Constraints There are two constraints that need to be considered when evaluating lowering of the storage level. These are: 1.' Maximum possible releases from Coolmunda reservoir; and 2. Flooding impacts downstream. 8.1.1 Maximum possible releases from Coolmunda Dam The release rate from the storage may be governed by the storage level at the time of drawdown. Coolmunda Dam has two possible mechanisms, which can be operated simultaneously. They are: The following table indicates the total number ofdays required todewater Coolmunda Dam from Full Supply Level using the available outlets. A spillway discharge curve is given on page 4.

(i) "Failure Due To Flood":- The inflow of an extreme flood into the storage causes overtopping leading toerosion failure ofabutment orfoundations. (ii) "Sunny Dam Failure":- In which the dam fails under a normal inflow situation. Any flood inundation would result from water held in the storage.

These are: Local Government • Disaster District • State Government A fourth level, The Commonwealth, is also included inour Disaster Management System recognising that Queensland may need to seek Commonwealth support intimes ofdisaster. Each ofthese levels within the Queensland Disaster Management System has as itsbasis a committee structure supported bya disaster coordination centre. These committees and coordination centres are activated when required to manage and coordinate support fordisaster stricken communities. When not activated, these committees meet to prepare forand practice their role within the Disaster Management System.

Management ofa disaster atthe community level isconducted byLocal Government who are responsible for the implementation oftheir Local Disaster Management Plan. If Local Governments require additional resources tomanage the event, tI1ey are able torequest support from their Disaster District Coordinator. This allows for the rapid mobilisation ofresources ata regional ordistrict level. If Disaster Districts resources are inadequate orinappropriate, requests for assistance can be passed toState via the State Disaster Coordination Centre. Finally, when State resources are inadequate orinappropriate, support from the Commonwealth can be obtained via Emergency Management Australia (EMA1.

(Formerly called Local Government Counter Disaster Committee). Local Disaster Management Groups (local groups) coordinate the response toadisaster ata local level. The Committees are usually chaired bythe Mayor and the Local Government Chief Executive Officer isusually the Executive Officer of the committee. Local Government Counter Disaster Committees develop and maintain Counter Disaster Plans for their Shire. These Local Government Committees are best placed todecide what resources are needed, when they are needed and how best toapply such resources soas tominimise hardship and suffering. They playa key role inthe Queensland Disaster Management System. District Disaster Management Group (formerly called Disaster District Control Group). There are 23 Disaster Districts inQueensland which are based on the Police Districts. The senior Police Officer ineach district is designated asthe Disaster District Coordinator who Chairs a Disaster District Control Group. These Disaster District Control Groups comprise representatives from regionally-based Queensland Government departments who are able toprovide and coordinate whole-of-government support todisaster stricken communities. The Disaster Districts perform a 'middle' management function within the Disaster Management System byproviding coordinated State Government support when requested by Local Governments. The State Disaster Coordination Group (SDCG) isthe working body ofthe State Disaster Management Group (State Group) atState-level. SDCG members are designated liaison officers from each ofthe Departments represented on the State Group. This Group isthe primary mechanism through which coordinated whole-of government State-level support is provided todisaster-stricken communities. The Stale Disaster Management Group. The State Disaster Management Group (State Group) isestablished as the principal organisation under the new Act forthe purposes ofdisaster management throughout the State. It replaces the State Counter-Disaster Organisation and itsexecutive, the Central Control Group. Inparticular, the State Group is responsible fordisaster mitigation and disaster planning and preparation ata State level and for coordinating whole-of-Government response and recovery operations prior to, during and after a disaster impact. This includes accessing interstate and/or Commonwealth assistance when local and State resources are exhausted ornot available. The State Group comprises Chief Executive Officers (CEO's) from all Queensland Government Departments. The CEO of the Department of the Premier and Cabinet isthe Chair, while the Executive Director ofCounter Disaster and Rescue Services isthe Executive Officer. Major Incidents Group (MIG). The Queensland Government has established a MIG toprovide high level Ministerial guidance and support inthe eventof a significant incident with major community consequences. Conceptually, membership of the MIG would be determined on an incident-by-incident basis and may include, but notbe limited to: Premier (Chair) Treasurer Attorney-General Minister for Police Minister for Emergency Services Minister forHealth Reference: http://www.disaster.qld.gov.au/abouU SunWater Section 10: Page 7 of 9 Jan 08, Issue 2-0 EMERGENCY ACTION PLAN - COOLMUNDA DAM WEATHER INFORMATION (FLOOD WARNING) Using the Internet http://www.bom.gov.aul fit'" iaM' !'fif!li ~'..~.,''''''"~'>m< X'I':"""' .....'
