Introduction Australia has adopted a comprehensive and integrated approach to the development of its arrangements and programs for the effective management of emergencies and disasters. This approach is: comprehensive, in encompassing all hazards and in recognising that dealing with the risks to community safety, which such hazards create, requires a range of prevention/mitigation, preparedness, response and recovery (PPRR) programs and other risk management treatments; and integrated, in ensuring that the efforts of governments, all relevant organisations and agencies, and the community, as a prepared community, are coordinated in such programs. Ultimately, the goal of all such arrangements and programs is to contribute to the development and maintenance of a safer, sustainable community. Within New South Wales the State Emergency Management Committee has adopted the methodology of Emergency Risk Management (ERM) to facilitate the integrated national approach. ERM is a process which involves dealing with risks to the community arising from emergency events. It is a systematic method for identifying, analysing, evaluating and treating emergency risks. At a local level, Local government is a key stakeholder in the ERM process because it is usually the first level of support for communities in emergencies and it also plays an essential role is supporting the Local Emergency Management Committee.

Purpose The Lithgow City Local Emergency Management Committee is working to create a prepared community and therefore safer community in conjunction with Community, Emergency Services and other identified stakeholders to create a holistic Community Risk Based Emergency Management Plan which addresses natural, technological and biological risks that may affect this Community.

Objective The objective of the Emergency Risk Management Project is to create a prepared community by identifying, analysing, evaluating Natural, Technological and Biological risks that are appropriate to the Lithgow City and recommending treatment options based on the “Implementation Guide For Emergency Management Committees” developed by NSW State Emergency Management committee.

Authority The report was facilitated by Echelon Australia in liaison with the Local Emergency Management Committee Working Group. The draft report will be adopted by the full committee at the local level.

1.0 EXECUTIVE SUMMARY This Emergency Risk Management Report has been prepared in accordance with the NSW State Emergency Management Committee’s “Implementation Guide for Emergency Risk Management”. The report considers the risks associated with a range of Natural, Technological, Biological and Other hazards that, if any of the hazards occurred, would require a “significant and coordinated emergency response” within the meaning of Section 4 of the State Emergency and Rescue Management Act 1989 (as amended).

The report forms the basis for discussion of these hazards in terms of current arrangements, preparation and risk assessments. This process is not intended to replace current plans and arrangements for the management of emergencies, but rather to provide a coordinated view of the emergency response preparation in our community.

The Local Emergency Management Committee is not required to implement treatment plans.

The Lithgow City Emergency Risk Management Working Group developed their view of the hazards on the basis of exposure across the entire Lithgow City Local Government Area (LGA), identifying examples where each hazard type would have what was considered to be the greatest impact. The Committee accepts that a hazard may occur anywhere in the LGA or may create differing impacts on specific areas of the community.

The Community Hazard Matrix was developed to differentiate between hazards that the group believed are:

• not relevant in the LGA, or not requiring a multi-agency response if the hazard occurred, and those

• expected to occur and would require a multi-agency response.

Appendix 3 lists those hazards requiring no further action, including reasons why the view was taken.

Risk Statements were developed for the remaining hazards. The risk level of these situations was analysed and the assessment is contained in Section 6 of this report.

In summary, of the 38 hazards assessed, 5 were considered to present and extreme risk, 15 to present a high risk, 10 to present a medium risk and 8 to present a low risk to the community.

The hazards assessed as presenting extreme and high risks, and the risk statement relating to each are listed in the Table on the next pages.

The identified mitigation and control strategies were not tested. In many cases the responsible combat agency identified existing strategies, in other cases the issue was referred to the relevant combat agency for action.

3.0 ERM CONTEXT STATEMENT The aim of the Lithgow Emergency Risk Management project is to develop and implement a ‘Community Emergency Risk Management Plan’ for the Local Government Area of Lithgow City, in consultation with the wider community.

The process examines natural, biological, technological and other risks that in the event of an emergency, would require a “significant and coordinated emergency response” within the meaning of Section 4 of the State Emergency and Rescue Management Act 1989 (as amended).

Lithgow City Local Emergency Management Committee (LEMC) is managing the emergency risk management plan development process. The NSW State Emergency Management Committee ‘Implementation Guide for Emergency Risk Management (NSW)’ has been used to undertake this process.

A community consultation strategy has been developed by the LEMC to ensure that the community is consulted during the process and adequate and equitable access is provided to all areas of the community.

3.1 Identified problems The working party of the Local Emergency Management Committee have been charged with the task of reviewing and or identifying natural, technological, biological and other hazards that impact on the Lithgow City Local Government Area only.

3.2 Process limitations 3.2.1 Legislation

1. The role of LEMC is as defined in the State Emergency and Rescue Management Act 1989. 2. Each agency as a member of the LEMC whilst operating under the SERM Act also have

agency specific policy and legislative requirements that may impact on their ability to share and table operational information.

The following legislation also applies to each of the positions within the LEMC

Chairperson Section 28 2a “a senior representative of the council of the relevant local government area nominated by that council, who is to be the Chairperson of the Committee” Section 29 “The Chairperson of a Committee is to be a person who has the authority of the council to co-ordinate the use of the council's resources in the prevention of, preparation for, response to and recovery from emergencies”

Emergency Services Representative Section 28 2b “a senior representative of each emergency services organisation operating in the relevant local government area” Section 28 5 “The representative of an organisation is to be nominated by the organisation” Functional Area Representative Section 28 2c “representatives of such organisations providing services in functional areas in the relevant local government area as the council of that area may from time to time determine

Legislated Council Responsibilities Section 32 Councils to provide executive support for Local Emergency Management Committee and Operations Controller.


10

(1) A council is to provide executive support facilities for the Local Emergency Management Committee and the Local Emergency Operations Controller in its area.

(2) The principal executive officer is to be known as the Local Emergency Management Officer

3.2.2 Policy Issues Member agencies of the LEMC operate within individual policies that are specific to their organisations some of which are restricted will not be recorded within the Emergency Risk Management Study. These issues are however discussed at a local and district level within the management committee structure to ensure a whole of LGA response is adopted.

3.2.3 Scope 1. The LEMC is only required to consider hazards that impact on people, property, animals

and or the environment that would have the potential to require a significant and coordinated multi-agency response.

2. The Wellington LEMC and its working group is to document the process as outlined within the NSW State Emergency Management Committees’ “Implementation guide for emergency management committees”

3. The LEMC is not required to implement treatment plans. 4. Where a lead combat agency or functional area has been identified as having a legislative

requirement to plan for and or mitigate for identified hazards, the LEMC is restricted to asking the particular agency to produce current planning and mitigation documents or status reports

The SEMC makes final comment on any plan developed by a LEMC via its Assessment Checklist released in December 2006.

3.2.4 Concurrent Studies

Whilst Council does not have any studies being undertaken concurrently with the Emergency Risk Management process, Council is planning on undertaking a number of studies in relation to emergency risk management treatments after the adoption of these plans by the SEMC.

3.3 Management framework 1. The management framework for the Lithgow City LEMC is identified in appendix one (1) of this

document.

2. A summary of the project management plan appears in Section 2 of this document.

3. Management framework overview: • Working Party formed as sub committee of LEMC and charged with undertaking the

Emergency Risk Management Study. • At each stage as identified in the project plan the full LEMC is briefed by the working group and

consensus is achieved before moving to the next stage. • At the completion of the Study the document will be presented to the LEMC for adoption and

then endorsement by Council. The completed document will then be forwarded to the SEMC via the DEMC.

3.4 Risk evaluation criteria The risk evaluation criteria adopted by the Lithgow City Local Emergency Management Committee are: 1. Any reasonably preventable accident/incident resulting in loss of life is unacceptable.

2. Any reasonably preventable accident/incident resulting in serious injury is unacceptable.

3. Any reasonably preventable matter that will affect the health and wellbeing of a community is unacceptable.

4. Any reasonably preventable activity or incident that will have a medium- to long-term or permanent effect on the environment is unacceptable.

5. Any reasonably preventable activity or incident that will have a long-term or permanent effect on the cultural assets and values of a community is unacceptable.

6. Any reasonably preventable activity or incident that will seriously disrupt normal business activity is unacceptable.

7. Any reasonably preventable activity or incident that will seriously disrupt community lifelines or services is unacceptable.

8. Any reasonably preventable activity or action that could lead to the introduction of exotic diseases or pests is unacceptable.

4.0 COMMUNICATION STRATEGY Local Government by its very nature is constantly engaging and consulting with its community on a range of issues. It understands that community engagement is the process of working collaboratively with groups of people affiliated by geographical proximity, special interest or similar situations to address issues affecting their well-being. As such there are a number of strategies and networks in existence within the local government context that can be utilised for the Emergency Risk Management Process.

Community engagement incorporates consultation (information sharing) and active participation between the stakeholders. It strengthens the capacity of communities to take action that produces positive and sustainable changes locally. It has be the intent of the Local Emergency Management Committee to tap into the existing networks to engage and consult with the community on the Emergency Risk Management Study with the following aims:

i. To enable the community to be better informed about hazards within their community ii. To reduce the level of misconception or misinformation about the ERM process iii. To ensuring commitment and greater ownership of the final decisions reflected within the

Emergency Risk Management Study iv. To encourage the community to put forward ideas and assist in the recording of hazard

history for the local government area v. Enabling the Local Emergency Management Committee to gain a better understanding

of local expectations in relation to PPRR issues vi. To help to identify issues which may not otherwise have been considered by the LEMC

4.1 Community Consultation

The Lithgow City LEMC determined the following communication strategy for this project:

4.1.1 The Lithgow City LEMC consists of representatives of combat agencies operating within the Lithgow City Local Government area.

4.1.2 The Committee considered that due to the high level of local familiarity with issues and stakeholder groups possessed by Committee members, the Committee was capable of developing a draft Emergency Risk Management Report that represents the community’s views.

4.1.3 The Committee proposed that when the draft document is compiled a report will be submitted to Council regarding the draft and the process followed to develop the draft;

4.1.4 Community consultation will be initiated by public advertisement and press release calling for comment on the draft document.

4.1.5 Community feedback will be available via the Echelon Australia website (http://www.echelonaustralia.com.au/centroc/index.aspx), or written submission to Council, with the public display of the documentation to follow Council procedures.

4.1.6 Responses to this community comment will be considered and any appropriate amendments will be made to the document, prior to formal adoption by the Committee and Council.

4.2 Process Documentation (Evidence of Process) Minuted meetings were held on each of the dates listed in Appendix 2 of this document. Reference should be made to these minutes to determine attendance and decision making processes. The Local Emergency Management Officer holds all minutes. Appendix 2 also lists the activities addressed by the Working Group throughout the process.

5.0 RISKS 5.1 Lithgow City LGA Community Hazard Matrix The Implementation Guide for Emergency Management Committees includes a Hazard Checklist, with the direction that “all hazards on the Hazards Checklist must be described”. Where additional hazards beyond those included in the Checklist are present in an area, these should be added to and considered along with the Checklist contents. In assessing the hazards identified on the Checklist, it becomes clear that a number do not apply in the Lithgow City LGA. The following tables represent the initial hazard identification identified by the Lithgow City LEMC Working Group.

Those hazards assessed as falling outside the criteria set for this report have been identified and shaded (see below). There is no further action to be taken on these hazards within this context of this report, other than their inclusion in the schedule in Appendix 3 Hazards Requiring No Further Action attached to this report. This schedule also states the reasons why these hazards were not considered relevant or present in the Lithgow City LGA.

All other hazards have had risk statements developed to further define the hazard as it can be expected to present in the LGA. Risk assessments are conducted based on these Risk Assessments and the assessments are contained within this report.

The Lithgow City LEMC determined that emergency exposure and response capability are generally consistent across the Lithgow City LGA, and hence the LGA could be assessed as a homogenous unit.

5.2 Natural Hazards – A National Perspective

The European colonization of Australia – and its written history – began at Sydney Cove in 1788. With only 20 million people spread across 7.7 million km2, even today parts of the continent are not exactly overcrowded. As an example, Australia Post divides the county into 2,433 postcodes, each with an average population of about 8,200. The largest postcode (872 in Western Australia) had a population at the 2001 Census of 20,400; the postcode covers an area of 621,400 km2 an area significantly larger than France. While it could be argued that nothing much happens, from a natural hazards point of view, in postcode 872, that was exactly the rest of the nation’s view of Canberra, the national capital – except that this view changed in January 2003 (Russell Blong, Issues in Risk Science, 2004). Nearly twenty years ago, researchers at Macquarie University in Australia, in what was later to become the insurance industry-sponsored research centre known as Risk Frontiers, began compiling databases on natural hazards and their impacts in Australia. An integrated data base is the result that contains more than 5000 hazard occurrences and information about human deaths and damage to the built environment resulting from nine natural perils – Tropical cyclones, bushfires, floods, wind gusts, tornadoes, hailstorm’s, earthquakes, landslides and tsunami. 5.2.1 Summary of Deaths Due to Natural Hazards 1788 – 2003

PERIL FIRST RECORDED DEATH NUMBER OF DEATHS %TOTAL DEATHS

Earthquake 1902 16 0.3Landslide 1842 95 1.6Bushfire 1850 696 11.4Thunderstorm 1824 774 12.7Tornado 1861 52 0.9Cyclone 1839 2163 35.5Flood 1790 2292 37.6Tsunami 0 0.0Total 6088 100

Issues in Risk Science 2004 Tropical cyclones and floods together account for more that 70% of known natural hazard deaths since the European colonisation of Australia in 1788. Thunderstorms, particularly lighting, and bushfires each account for 11 to 13% of deaths, indicating that the other hazards considered have produced very few human deaths, al least in the last 200 years. At the other end of the spectrum, deaths in earthquakes, landslides and tsunamis combined account for less than 2% of all deaths. This paltry total reinforces the view that Australia is a land of meteorological perils; a low lying, ancient continent with all its sea coast remote from the active boundaries of tectonic plates is unlikely to be dominated by geological hazards. If we delve into the totals a little further we discover, for example that while flood deaths average 10-11 per year, one quarter of all flood deaths have occurred in New South Wales. Bushfire deaths have averaged about 4 per year with 50% of all deaths in just eight fires or, more accurately, on just eight days of extreme fires. Lightning deaths (that is most of the thunderstorm deaths) average about 3.5 fatalities per year, with nearly half in NSW.

5.5 Community & Environmental Description

5.5.1 Lithgow City Council Local Government Area

Lithgow City has an area of 4,551 square km, located in the Central Tablelands of New South Wales, approximately 247 kilometres (two and half hours) by road from the centre of Sydney. Surrounding Councils include Bathurst Regional Council, The Oberon Council, Blue Mountains City Council and Mid Western Regional Council.

5.5.2 Demographic factors

The population of Lithgow City Local Government Area is 20,296. Lithgow, with a population of approximately 11,000, is the major town in the Local Government Area. Other villages / districts include Portland, Wallerawang, Marrangaroo, Hartley, Hampton, Sodwalls, Tarana, Rydal, Meadow Flat, Angus Place, Cullen Bullen, Ben Bullen, Capertee, Newnes, Glen Davis, Glen Alice, Bogee, Lidsdale, Clarence, Kanimbla Valley, Dark Corner, Sunny Corner, and Wolgan Valley.

The largest areas of employment in the area are in mining, wholesale and retail, and manufacturing, as well as the provision of community services.

5.5.3 Geographic factors

Lithgow is characterised by its rugged landscape of steeply vegetated hills, valleys, watercourses, sandstone escarpments and intermittent settlement. Approximately 50% of the Local Government Area is zoned and used as reserves, national parks and forestry.

Lithgow is in the Central Tablelands weather forecasting district. The area has cool to cold winters and mild to warm summers. The average yearly rainfall is 860 millimetres, with occasional light snowfalls in winter as well as frequent frosts. Quite cold conditions can be experienced at any time throughout the year. Prevailing winds tend to be either easterly or south-easterly in summer and westerly or south-westerly in winter (source Bureau of Meteorology – Bathurst Wind Rose). The average temperatures are - summer 25.50C (max) and 11.80C (min) and winter 10.40C (max) and 0.70C (min).

5.5.4 Land use

Within the Lithgow Local Government Area, there are ten (10) identified zones, being

Rural (General) – 46.66% of Local Government Area

Rural (Small Holdings) – 0.74% of Local Government Area

Rural (Future Urban) – 0.10% of Local Government Area

Rural (Forestry) – 14.89% of Local Government Area

Residential – 0.19% of Local Government Area

Village – 0.18% of Local Government Area

Business – 0.01% of Local Government Area

Industrial – 0.02% of Local Government Area

Open Space – 0.24% of Local Government Area

National Parks and Nature Reserves – 35.53% of Local Government Area

(Roads and Unmapped Areas – 1.42% of Local Government Area)

Significant amounts of lands zoned as Rural (General) are not necessarily used for agricultural purposes, with other uses such as mining exploration, private forestry, and private conservation agreements taking place in this zoning.


24

There are a number of constraints and opportunities to develop in and around the Lithgow township, including mine subsidence areas, state and regionally significant mineral resources, and steeply vegetated hills and environmentally sensitive land.

Due to the lack of suitably sized land, many trade and business services are located within the industrial zone, further reducing the area of land available for purely manufacturing and industrial purposes in the Lithgow area. Current vacant land zoned industrial presents an opportunity for bulky goods uses to link to the town centre and residential areas.

The Rural Residential Development Control Plan allows a two (2) hectare subdivision subject to development requirements to manage impacts. Statistics suggest that there is additional Rural Subdivision potential available.

There are also three (3) area within the Local Government Area which are zoned for future urban use, including 304.9 hectares at West Bowenfels, 150.9 hectares at Wallerawang and 115.43 hectares at Portland.

5.5.5 Transport

5.5.5.1 Road

Two major transport systems traverse the Lithgow Local Government Area, being the Great Western Highway (State Highway 5) and the Main Western Rail Line. Both systems provide major transport links from central western New South Wales through to the eastern sea board of the State.

In addition to the Great Western Highway, a series of Main Roads and other secondary road networks provide links to and through the other towns and villages in the LGA. The Bells Line of Road also provides and alternative route across the Blue Mountains and into the north western sector of Sydney.

Lithgow is also the starting point for State Highway 18 (Castlereagh Highway), which links Lithgow to north western areas of the State via Mudgee.

5.5.5.2 Rail

Train movements through Lithgow include an eastbound and westbound XPT passenger service each day, as well as upto ten (10) eastbound and ten (10) westbound freight train movements daily. East of Lithgow, metropolitan services run on average eight (8) times per day. A connecting bus service runs three (3) times daily between Lithgow and Bathurst, and eight (8) times daily between Lithgow and Portland.
