1 Executive Summary

The Wellington Shire Council together with the West Gippsland Catchment Management Authority (WGCMA), Environmental Protection Authority (EPA) and community representatives are developing an Urban Storm Water Management Plan (SWMP) to provide Council with a guide for developing and controlling stormwater quality discharge from the major population centres.

The development of the Storm Water Management Plan is being undertaken in accordance with the CSIRO document Urban Stormwater — Best Practice Environmental Management Guidelines — Chapter 3 Storm Water Management Planning.

This report forms Stage 3 of the Guidelines which requires an Issues Paper that identifies priority management issues established through the risk assessment process and from a review of Council's management framework including planning and operational management. The urban systems which are considered in the SWMP include the large urban centres of Sale/VVurruk, Heyfield, Maffra, Stratford, Rosedale and Yarram; together with the smaller centres of Dargo, Licola Briagolong, Coongulla, Boisdale, Newry, Tinamba, Cowwarr, Loch Sport, Longford, Seaspray, Alberton and Port Albert.

The most significant threats to those urban systems were found to be:

• Litter and sediment runoff from the residential and commercial areas of the larger centres;

• Industrial discharge and site runoff;

• Open space (sporting facility) discharge to receiving environments;

• Lot scale development building site discharge and site runoff;

• Impacts of septic and sewer leaks and spills.

These stormwater threats impact upon the values and beneficial uses of the receiving waterways including the waterway's: environmental values; recreational and visual amenity; the cultural importance; stormwater conveyance and treatment capacity; and the associated economic benefits of the waterway.

These impacts are not only limited to the immediate urban receiving waters but encompass the broader scale of our waterway systems including the Gippsland Lakes, wetlands, coastal and marine park systems. The examination of the influence that urban stormwater threats has on the receiving water values forms the measure of risk used to develop priority issues.

The Wellington Shire is currently considered to have a sound management framework directed towards minimising the effect of urban stormwater pollution on receiving water values. Yet the issues analysis has identified a number of key issues which require resolution to improve stormwater quality.

EARTH TECH D-WS SWMP Issues Paper Rev2.doc July 2002 Wellington Shire Council Stormwater Management Plan Page 2 Priority Management Issues Paper

These issues exist within Councils current management framework as follows:

• Need for strengthening of planning tools and strategic documents, to form a statutory basis for requiring Best Practise Management as part of permit conditions.

• Opportunity to more clearly define the referrals process including triggers for internal referrals, roles and responsibilities.

• Need for continued support for the allocation of resources for planning condition enforcement.

• Need for amendments to municipal operation procedures, incorporating Best Practise techniques.

• Opportunity for the use of educational and awareness programs, focused towards Council staff, and also toward the construction industry and the general community.

• Need for of the support of litter enforcement if required.

This paper identifies these Priority Management Issues as a precursor to developing strategies to address them as part of the Stormwater Management Plan. This provides Council with the opportunity to access part of the $22.5 million which is available over three years through the Victorian Stormwater Action Program to fund works and programs with the principle goal of 'improving the environmental management of urban stormwater'.

2 Introduction

2.1 Background to the Paper A Stormwater Management Plan (SWMP) is currently being developed for the urban areas in the townships of Wellington Shire. The Management Plan is focussed on achieving improvements in stormwater quality by identifying priority management issues and developing strategies and actions to be undertaken by the Council and other agencies to address the issues. The plan will promote and encourage best practice for urban stormwater management.

Improvements in stormwater quality will have beneficial effects on the water based environments in and surrounding the urban areas of Wellington Shire, as well as downstream environments including the Gippsland Lakes. The SWMP study areas include the large urban centres of SaleNVurruk, Heyfield, Maffra, Stratford, Rosedale and Yarram; together with the smaller centres of Dargo, Licola Briagolong, Coongulla, Boisdale, Newry, Tinamba, Cowwarr, Loch Sport, Longford, Seaspray, Alberton and Port Albert.

A prescriptive process for preparing stormwater management plans has been developed and is coordinated through the Government launched Victorian Stormwater Action Program (VSAP) by the EPA. The principle goal of VSAP is to improve the environmental management of 'urban stormwater' in Victoria. The process is being achieved through the adoption of integrated urban stormwater management by councils as outlined in the Best Practice Environmental Management Guidelines for Urban Stormwater (CSIRO, 1999). The SWMP development process is illustrated in Volume 2 Section 1.1 of the Plan. Development of the Stormwater Management Plan for Wellington Shire is being led by the Wellington Shire Council, West Gippsland Catchment Management Authority, EPA and environmental consultants ID&A Pty Ltd as part of Earth Tech Engineering Pty. Ltd. The process involves consultation with a range of invited parties through a series of four workshops. At this stage, two of the workshops have been completed.

2.2 Purpose of the Paper The purpose of this Priority Management Issues Paper is defined in the Guidelines as follows: To clearly describe and achieve agreement on the key stormwater risks and management framework deficiencies which are limiting the achievement of best practice. Key risks to stormwater quality have been identified through a risk assessment process, and the findings are summarised in this paper. The two completed workshops were integral to the risk assessment process and in identifying the sub-catchmentspriority issues. The risk assessment was carried out for a number of separate identified within each of the townships.

A review of Council's management framework was also carried out and is described in this paper with reference to best practices. Finally, the priority management issues are identified by considering the interaction between current management practices and the key risks.

3 Risk Assessment Method

In the context of the stormwater management plan, risks are defined as activities within the catchment that can have an adverse impact on the quality of water in waterways or water bodies, and their associated values. Potential impacts are usually associated with pollutants transported by stormwater.

The method for determining risk priorities can be summarised by the following relationship:

Risk = Threat x Value x Sensitivity Where:

• A threat is an activity in the catchment that may pollute stormwater quality; )=. The waterway or water body that receives stormwater flows (the receiving waters) is valued for a range of factors including environmental, aesthetic, cultural and economic factors; and

• The sensitivity is a measure of the degree of impact upon waterway values resulting from pollutants transported by the stormwater. Scores have been allocated to the threats in each sub-catchment and to the values of the receiving waters through the workshop process. Sensitivity scores were also allocated to determine an overall risk score. All scores are from 1 to 4 so that the three factors combine to give a maximum risk score of 64 for each item in the risk matrices, which were used to calculate all risk scores. The risk matrices for the six larger urban centres together and relevant smaller centres are attached in Appendix Cl of Volume 2.

The scoring process is based on available information, but in many cases this is limited and so there is a degree of subjectivity to the scores. Debate is encouraged at the workshops with the aim of reaching agreement on the scores and the selection of priority risks. It is important to emphasise that the assessment is primarily concerned with stormwater runoff quality as opposed to runoff quantity. The nature of the scoring process as described above therefore focuses on 'protecting' existing higher valued receiving waters from existing high threat sources. Degraded waterways which currently carry low values are thus not addressed as a priority urban stormwater issue in this study.

4 Wellington Shire Urban Areas With the focus of the stormwater management plan directed towards 'urban' zones, Wellington Shire was divided into study areas based on geographic location and separation. Urban areas were defined according to the Wellington Shire Planning Scheme, and included residential, industrial, township, public use zones etc and were generally bounded by rural zones. The geographical separation between townships produced the study areas listed in Section 2.1. To enable the examination of issues specific to locations of interest within a study area, the study areas were further divided into sub-catchments, according to hydrological boundaries for runoff, outfall, and receiving environments, and land-use patterns for urban stormwater threats. The number of sub-catchments allocated per town therefore varied according to terrain, and uniformity of stormwater threats and theirsub-catchments impacts on receiving water values. A layout of selected towns and their is attached in Appendix G of Volume 2. The sub-catchment numbers shown on these layouts are referred to throughout this document. The following discussion summarises outputs from workshops 1 and 2, and forms the basis to which priority issues are identified. The study areas have been broken up into two groups: the six large urban areas which were examined through the project working group consultation, and the 13 smaller urban areas which relied on field investigations, discussions with Shire Officers and the review of various reports.

4.1 Sub-catchments of Sale Sale has been divided into three urban sub-catchments. Sub-catchment (1) is made up by the North and West regions of the township which drain to Flooding Creek, and comprises a mix of residential, commercial and industrial land. Flooding Creek includes the Sale Canal, and together they are highly valued for boating and generation of tourism from boating activities, and is sensitive to the visual appearance of water. Sub-catchment (1) poses a high threat to these values from sediments, nutrients, litter and toxic chemicals resulting from residential, industrial and commercial land use runoff. This sub-catchment has also been identified as an area for future development and has been identified to have high threats from sediments and construction waste resulting from building site runoff. The values associated with receiving waters from this sub-catchment are also and highly vulnerable to impacts from sewage leaks arising from a sewerage pump station in close proximity to the Sale Canal.

The remainder of the Sale urban area drains to Lake Guthridge. This area has been split up into two sub-catchments. Sub-catchment (3) which isolates the major commercial centre of the town and sub-catchment (2) which is made up of the remaining urban area to the east of town, which is predominantly residential. Lake Guthridge is central to the township and has high values associated with recreational and property benefits. It is very highly valued for its visual appeal and the associated tourist attraction. It has high visitation by residents and tourists, and is very popular for relaxation, and bird watching. The perimeter track receives significant use for recreational walking. The values of Lake Guthridge are considered to be at high or very high risk from the urban runoff, in particular from litter, sediments and toxicants from commercial land runoff in sub-catchment (3), and also residential land use runoff, from building

D Issues Paper - WS SWMP Rev2 doc July 2002 Wellington Shire Council Stormwater Management Plan Page 6 Priority Management Issues Paper

construction runoff and sporting facility (pool) discharge from sub-catchment (2).

4.2 Sub-catchments of Heyfield Urban runoff from Heyfield drains to the Thomson River. The majority of this runoff is initially received by the Heyfield Wetlands, which has been constructed central to the township as an attractive feature. The wetlands also serve the function of stormwater treatment. The study area has not been divided into multiple catchments, due to the uniformity of the land use activities and common drainage paths.

Both the Heyfield Wetlands and Thomson River possess high values of in-stream habitat, recreational amenity, including swimming, visual/landscape amenity, and in the case of the Heyfield Wetlands a high benefit in water quality treatment. The threats to these values however are in general only considered moderate except for industrial site runoff, which is considered high for the Heyfield wetlands, generating sediments and chemical pollutants in runoff.

4.3 Sub-catchments of Maffra The Maffra study area drains to two receiving waters, the Macalister Swamp and the Macalister River. The Macalister Swamp is a man made swamp which now attracts many bird and wildlife species and is highly valued for its in-stream habitat, riparian vegetation, its recreational and visual amenity and its capacity for stormwater quality treatment. The Macalister Swamp eventually drains into the Macalister River. Similarly, the Macalister River has high values for in-stream habitat, riparian vegetation,non-motorised and recreational amenity including swimming and recreational boating. It is also very highly valued for its visual amenity, and the economic benefits derived from water supply and tourism. The Macalister River is also highly valued for its cultural significance. Maffra's sub-catchment (1) to the north west of the town drains to the Macalister Swamp. The predominantly residential area has a high threat from litter, sediments, and from other inappropriate dumping associated with residential land use. Sub-catchment (2) to the south of the town includes the Maffra CBD and the industrial areas. It has been classed at having high threats from sediment and nutrient transport from industrial land runoff'; and litter, leaf litter, and inappropriate dumping from commercial land use runoff. Sub-catchment (3) to the north east has a generally low level of urban activity and is not considered to pose a significant stormwater threat.

4.4 Sub-catchments of Stratford The urban area of Stratford is divided into two drainage sub-catchments. Stratford sub-catchment (1) to the north which drains to Blackall Creek, and (2) to the south which drains to the Avon River. While Blackall Creek has moderate in-stream habitat values, the Avon River has very high visual/landscape and recreational amenity, which includes swimming, fishing and water play. The Avon River has also high in-stream habitat values and associated high tourism values.

EARTH TECH D - WS SWMP Issues Paper Rev2.doc July 2002 Wellington Shire Council Stormwater Management Plan Page 7 Priority Management Issues Paper

The values of Blackall Creek are most heavily threatened by sediments transported from eroding drains and unstable/degraded waterways. The values and beneficial uses of the Avon River are subject to moderate threats from litter, sediments, chemical toxicants and inappropriate discharge from residential, industrial and commercial land use runoff.

4.5 Sub-catchments of Rosedale Rosedale is a single drainage catchment which drains into Blind Joes Creek, and then into the Latrobe River. Blind Joes Creek runs along the northern edge of the town and has moderate values for in-stream habitat, riparian habitat and for stock watering. These values are moderately threatened by litter, sediments and inappropriate discharge to the stormwater system, from a range of sources including residential, industrial and commercial land use runoff. The transport of these pollutants to the Latrobe River will adversely impact on its moderate values of in-stream habitat, and recreational and visual/landscape amenity.

4.6 Sub-catchments of Yarram The greater majority of the urban land area of Yarram makes up sub-catchment (1), which drains by way of outfall drains some 6km to Albert River. Although there is a considerable distance between the urban source and Albert River, it has been considered in the SWMP as the receiving water, because urban stormwater from Yarram is still conveyed to it with the great majority of its contaminants.

A small area at the north of urban Yarram, sub-catchment (2), drains to the Tarra River, which is not considered to be a significant threat. Sub-catchment (1) includes areas of residential, industrial, commercial and open space land use, which produce large quantities of litter, sediments, nutrients and chemical toxicants to the stormwater system.

This level of pollution poses a high threat to the highly valued recreational beneficial uses of the Albert River in particular fishing and boating, together with the visual amenity of the area and the associated tourism benefits. Albert River is also very highly valued for its in-stream habitat, particularly its fish life, and highly valued for its native riparian habitat and flora species. Although the Tarra River has similar values to those of the Albert River, its urban sub-catchment (2) due to its very small size presents /ow risk to those values.

4.7 Sub-catchments of Coongulla Coongulla has been considered as a single sub-catchment which drains to Lake Glenmaggie which it is situated beside. Lake Glenmaggie has very high values and beneficial uses which include recreational amenity derived from boating, swimming and water play; visual amenity from the natural beauty of the water body; and also economic benefits from tourism, water supply and property values. Lake Glenmaggie is considered to have high threats from septic leakage from Coongulla sub-catchment (1). Due to interrelated moderate threats from residential land-use runoff and unstable waterways, poor stormwater conveyance and

D - WS SWMP Issues Paper Rev2 doc July 2002 Wellington Shire Council Stormwater Management Plan Page 8 Priority Management Issues Paper

unsuitable soils leads to considerable septic leakage, to which the receiving water values and public health are highly sensitive.

4.8 Sub-catchments of Seaspray The urban area of Seaspray has been divided into two sub-catchments according to the drainage/pump paths. Two waters receive this stormwater runoff which are Merrimans Creek and Lake Reeve. Lake Reeve has very high environmental values for in-stream habitat and riparian habitat, while Merrimans Creek has high values for recreational and visual amenity.

As is the case at Coongulla, both Seaspray urban sub-catchments (1) and (2) have been considered to pose a high threat of septic leakage due to inadequate soil capacity and flat grades.

5 Priority Stormwater Risks The previous section examined the key issues pertaining to specific sub-catchments and receiving environments in the study areas. The risk assessment as described in Section 3 used this examination to produce scores relating to the priority of the specific risk, derived from the multiplication of their value, threat, and sensitivity score. The risk matrices used to assign these scores are attached in Appendix Cl of Volume 2. This produced a range of values, with the top 2 percentile being 36 or above (maximum possible is 64). Ranked lists of priority items are attached in Appendix C2 of Volume 2.

The issues which scored 36 or higher are displayed in Figure 1 below. It should be noted however that the overlapping issues have been grouped, ie the residential land use threat to Lake Guthridge in Sale sub-catchment (2) highly impacts upon the visual landscape, but also highly impacts the values of other economic, and recreation. Accordingly these values have been grouped together.

6 Management Framework Review In this section, current Council practices in stormwater management are reviewed. The Council's management framework covers the planning and management activities undertaken by Council staff that can influence the quality of stormwater runoff on both a long term and a day to day basis. The framework includes protection of stormwater runoff quality through planning functions, including strategic planning, the development approvals process, and the regulation and enforcement of these conditions. The framework also includes protection of stormwater runoff quality through source controls and other practises, including municipal operations and provision of services, education and awareness programs, and enforcement mechanisms. Emphasis on protecting stormwater quality has only become a management focus in recent years. Prior to this, the emphasis has been on conveying stormwater rapidly away from houses and streets to the local waterways often through gutters, pipes and other hard surface infrastructure, primarily to control flooding. Although the gaps between current Council thinking and activity, and 'Best Practice Environmental Management" (BPEM) are expressed below, Council practises were found generally to be consistent with those of Councils in other regional municipalities. These gaps can be used as a basis for highlighting stormwater issues and presenting opportunities for management improvement strategies.

6.1 Stormwater Quality Protection Through Planning Controls This section presents a review of Wellington Shire Councils planning functions and presents opportunity for changes towards best practise management in the areas of strategic planning, the development approvals process, and the regulation and enforcement of these conditions.

6.1.1 Land Use Strategic Planning A primary means of improving stormwater management processes and outcomes for Wellington Shire is by selectively controlling developments through the Council's land use and development planning framework. This framework is governed by the provisions of the Planning and Environment Act 1987 and the Wellington Planning Scheme. The Wellington Planning Scheme consists of:

• State Planning Policy Framework, zones and overlays and particular provisions. • Local Planning Policy Framework, comprising a Municipal Strategic Statement and local planning policies; as well as issue-specific schedules to the standard zone and overlay controls. The Municipal Strategic Statement (MSS) describes the role of the municipality in a regional context, sets out a broad vision for the future and links the objectives of the MSS to the Council's Corporate Plan. It also establishes objectives for land use and development and provides strategies for achieving these objectives.

Within the current MSS, there are a number of sections which provide a broad reference to objectives and strategies that provide a basis for incorporating Best Practise Stormwater Management. In many cases, the strategies are non-specific,

EAR TH E C H

D - WS SWMP Issues Paper Rev2.doc July 2002 Wellington Shire Council Stormwater Management Plan Page 12 Priority Management Issues Paper

and require strengthening by providing greater detail regarding stormwater quality protection. This also has implications regarding the enforcement of these conditions, as the objectives and strategies do not provide adequate statutory means to prescribe the incorporation of Best Practise in new developments.

6.1.2 Development Approvals Process The development approvals process incorporates the way in which development applications are reviewed and approved. Wellington Shire planners have a scheduled meeting once weekly, in which developments are openly discussed. During this meeting internal referrals are made to relevant planning or other departments. There are no formalised triggers which dictate if a development should be referred to a particular department (as for external referrals), but is based on the judgement of the attendees based on the application. There is an opportunity for incorporating Best Practise Stormwater Management for development approvals by formalising the triggers for referral within Council to specific Council departments which have the relevant function and experience. This would include guidance as to when approvals should be referred for expert review and who should be involved in the review. This would also include incorporating a range of checks required to review applications specifically regarding the impact of the development application and provide guidance on the range of measures which should be taken for Best Practise Stormwater Management. Wellington Shire Council has indicated its intention to prescribe stormwater treatment measures on new developments where relevant, such as gross pollutant traps on major outfalls to receiving waters. While such permit conditions have already been applied, amendments to the referrals and permit approvals, together with consistent amendments to the MSS and other strategic documents are now needed to formalise the incorporation of Best practise Stormwater Management.

6.1.3 Regulation and Enforcement of Planning Conditions The regulation and enforcement of planning conditions, relates to the ability to uphold the conditions of development set out in permits, and statutory documents. The ability to uphold these conditions is affected by the strength of the regulatory conditions and the utilisation of resources to enforce them. Council has identified a weakness in planning and building regulations, making it difficult to enforce Best Practise Stormwater Management. This is particularly so on construction sites, due to a lack of statutory support. This is not an issue specific to Wellington Shire, but is common throughout Victoria and would be assisted by changes to state legislation. Historically Wellington Shire Council has not engaged officers to enforce planning conditions, primarily due to lack of inclination and lack of resources. Recently there has been a part time position created for this purpose. The results of this role have proven very effective, with many non-conformances resolved early. This position also provides avenues to keep a close track on works and follow up measures. The Council intention is to broaden this enforcement role into other Council areas, which is a move towards Best Practise Stormwater Management and should be encouraged by relevant funding for resources.

6.2 Stormwater Quality Protection Through Source Controls and Other Practises

This section presents a review of Wellington Shire Councils source controls and other relevant practises. It presents opportunities for changes towards best practise management in the areas of municipal operations, provision of services, education and awareness programs, and enforcement mechanisms.

6.2.1 Municipal Operations and Provision of Services Wellington Shire has a comparatively small operations crew, which is split into two departments, open space and infrastructure which carry out various municipal works and services. Wellington Shire Council itself does not undertake construction activities, rather it engages contractors for the construction of roads, drains, buildings, open spaces etc. Such construction may potentially produce a wide range of stormwater pollutants from site and other runoff, including chemicals and sediments.

Best Practise Stormwater Management for construction activities includes a range of activities and practises to minimise the risk of pollutant runoff, eg. use of structural and vegetative measures, use of soil stabilisation techniques, use of site management plans, monitoring and recording of construction maintenance events.

These activities and practices can be required of contractors (which are currently not) by their inclusion into specifications. Such measures are not generally required as part of the Councils current construction specification. The development or amendments to asset construction and maintenance specifications or briefs, should include clauses which stipulate the need for consideration of stormwater quality Best Practise.

Wellington Shire Council's municipal operations include a number of activities which impact on the quality of stormwater runoff, those of greatest impact are discussed below. The Best Practice aim for all of these is to prevent waste material from entering the stormwater drainage system.

Street sweeping (kerb and channel) of the urban areas occurs by contract at various interval frequencies. Sale and Maffra Central Business Districts (CBD's) are swept three times per week, while the other CBD's are swept once per week. The remaining urban kerb and channels are swept on a two week turn around (half one week, the other half the next). Additional sweeping can be initiated by customer demand. The primary aim of street sweeping is for aesthetics and no additional programs are included for sweeping "hot spots", or to coincide with other activities (ie autumn leaf drop or festivals), as is for Best Practise. Maintenance of drains and pits is generally not done under a schedule or as a result of a monitoring program. Instead it is undertaken as a result of customer demand when an issue arises. This is with the exception of a number of open drains which are regularly sprayed to prevent the weed growth. Best Practise Stormwater Management of drains and pits in comparison should be planned and coordinated to ensure excessive build up of litter, silt, leaves and other pollutants does not occur, thus minimising the flush of this material into the receiving waters. This includes monitoring accumulation rates, and identifying "hot spots" which require more frequent cleaning and collection of the waste material with care taken not to sweep waste material further into the drainage system.

D - WS SWMP Issues Paper Rev2.doc July 2002 Wellington Shire Council Stormwater Management Plan Page 14 Priority Management Issues Paper

Council bin design and cleaning affects the amount of litter reaching the stormwater system. There are a range of bin types used in Wellington Shire, which are serviced on various frequencies. Many areas experience population expansion during holiday periods which place pressure on the bin placement and servicing system. The frequency for servicing is generally adjusted to meet demand, although some sections of the community see overflowing bins as a problem. Best Practise encourages the use of bin monitoring and change of servicing frequency to suit. Maintenance of parks, reserves, golf courses and medians includes cutting operations, which for Best Practise includes removal of grass clippings, litter and debris after cutting. This is generally not undertaken, however grass is usually cut with the shoe facing away from the kerb and channel. A bioactive herbicide is applied to specific areas to control flat weed, which has been classed as safe for sensitive fauna.

Emergency response to a stormwater impacting incident such as spills and other pollution, is not clear to many operators. Porous pillows for soaking up fuel and oils are available but their whereabouts or application is not commonly known. Best Practise Stormwater Management, for emergency response requires the formulation of an emergency response plan detailing the drainage system, location of ecologically sensitive areas, notification protocol for other emergency services, the council role and the appropriate use of equipment.

6.2.2 Education and Awareness Programs There are few formalised education and awareness programs which directly inform on issues relating to stormwater quality. Waterwatch as part of the West Gippsland Catchment Management Authority however, has run a number of programs including involvement with local school groups. These have included water quality monitoring and education, and stormwater pit lid stencilling — which creates a link between the drain and the water way. There are three areas identified as requiring particular education and awareness attention. Municipal staff coming from a background of little consideration of stormwater quality would benefit from a program to shift focus from traditional thinking, to ways of minimising the impact of urban land use on stormwater quality. This applies to the whole organization, with particular attention given to operational staff.

The second area requiring attention is the general community, focusing on inappropriate dumping into the stormwater system. This includes dumping of litter, oil, chemicals, grass clippings and other types of inappropriate material. The third area requiring education and awareness programs is the construction industry, both small (lot scale) and large (subdivision) development. Generation of construction wastes and site runoff can be significantly reduced if the industry is aware of the effects, and alternative Best Practise procedures.

6.2.3 Source Control Enforcement Wellington Shire Council's primary mechanism for preventing behaviour which may adversely impact on stormwater quality, is the application of local laws. Wellington Shire has a limited number of local laws that can be applied in relation to

TECH ©EARTHI4mm• D WS SWMP Issues Paper Rev2.doc July 2002 - Wellington Shire Council Stormwater Management Plan Page 15 Priority Management Issues Paper

stormwater, and enforcement is not generally seen as the preferred avenue for dealing with stormwater problem issues.

A local law is however in place concerning animal litter, and the State Litter Act can be applied, giving power for the control of both types of litter. Generally resources are not available to issue fines or infringements for these offences, as it is often very difficult to identify and apprehend the offender. There is however an acknowledged litter issue in various places within Wellington Shire.

7 Priority Stormwater Management Issues

The priority stormwater management issues highlight areas which present opportunities for the development of urban stormwater best practise management, and form the basis for strategies which are developed as part of the Stormwater Management Plan. From the discussion in the above sections together with the outcomes of the risk assessment, the stormwater management issues are made up of:

• Stormwater Risks - Priority Issues (Sections 4 and 5); and • Management Framework - Priority Issues (Section 6). These issues reflect the threats from land use activities in Wellington Shire and the actions or inactions of Council, which pose the greatest risks to the values and beneficial uses of the waters which receive the stormwater drainage from the urban land. These are also the issues which require priority attention to ensure Best Practice Management.

7.1 Stormwater Risk - Priority Issues 1. Residential Land Use Runoff — residential land produces large quantities of litter throughout the catchment which provides a highly visible pollutant, that significantly effects many receiving water values. This issue includes sediments which are produced from roads, gardens, parks, etc and include nutrients, micro-organisms and toxic trace metals which may be sediment bound.

Thesesub-catchments risks are highly evident in the two predominantly residential of Sale (1) and (2) which immediately effect Lake Guthridge and Flooding Creek. Yarram's Central Sub-catchment (1) which drains to the Albert River, and Maffra's North West Sub-catchment (1) which drains to the Maffra Swamp Reserve.

There are insufficient treatment devices to protect these receiving waters from sediments and litter. Also community understanding of the relationship between discharge to drains and the impact on waterways could be dramatically improved.

2. Commercial Land Use Runoff — commercial land also delivers high volumes of litter into the stormwater systems. However the sources are generally more concentrated, and hot spots can be identified. Sediments are also produced from road wear and vehicle movement. High traffic movement associated with commercial areas also produces concentrated vehicle discharges such as oil leaks. Commercial land use also contains the issue of inappropriate discharge, from businesses ie detergents from car washing premises and car yards, or oil from restaurants, or from public waste disposal. This issue has the greatest effect towards Lake Guthridge and Flooding Creek in Sale from sub-catchments (3) and (1) respectively (which includes Gippsland Centre Sale, the retail centre of the Shire), Albert River in Yarram fromsub-catchment sub-catchment (1), and Macalister River in Maffra from Maffra (2).

*WIWI EARTH E C H D - WS SWMP Issues Paper Rev2 doc July 2002 Wellington Shire Council Stormwater Management Plan Page 17 Priority Management Issues Paper

There are few measures to intercept or prevent commercial pollutants entering receiving waters. Many businesses operate using waste management practises which are harmful to receiving values (for example wash down of yards/paths into drains). Preferable practises could substitute these if known and promoted.

3. Industrial Land Use Runoff — industrial land may introduce contaminants to the stormwater system including sediments, nutrients, organics, and toxic chemicals used in production. These may have a devastating effect on many of the receiving water values and beneficial uses, and generally arise from site runoff from poor waste management and illegal discharge. This issue is most strongly present in Yarram affecting the Albert River from saleyard runoff in Yarram sub-catchment (1), in Sale from a number of industries including saleyards and oil and gas in Sale sub-catchment (1) which affects Flooding Creek. This issue also affects the Thomson River in Heyfield from sub-catchment (1) derived from the timber industry processing works and saleyards, and the Macalister River in Maffra from sub-catchment (2) derived from a number of industries including dairy processing and agriculture.

There are few discharge controls on non-licensed industries and little information held regarding discharge practise. There are opportunities to safeguard receiving waters through water quality treatment measures which are currently not employed.

4. Open Space/Sporting Facility Runoff — this issue relates to the discharge of chlorinated pool waste water including backwash water. This powerful disinfectant has serious implications for many of the values and beneficial uses of receiving waters. This issue has been identified to be most serious in Sale, with the pool in sub-catchment (2) discharging into Lake Guthridge.

A Pollution Abatement Notice was issued by the EPA on November 20 of 2000, requiring compliance with the State Environment Protection Policy (Waters of Victoria) No. S13. This policy places conditions on pool discharge which at the time were not being met. Designs for discharge modifications have been completed, and moves to satisfy these conditions are underway. This program requires monitoring and commitment, to expedite works for the resolution of this issue.

5. Building Site Runoff (lot scale) — lot scale development practise produces high concentrations of sediments and construction wastes which enter the stormwater system by site runoff (assisted by poor site management), or by inappropriate discharge, ie tipping of paints directly down drain. This issue has been identified to be strongest in Sale sub-catchments (1) and (2), where there are plans for new developments of significant size. Pollutants entering the stormwater system from these two sub-catchments will be received by Flooding Creek and Lake Guthridge respectively.

Together with planning conditions, site control measures could be enforced by EPA and Council regulation. Site control can be required at permit

approval stage. Industry education regarding Best Practise Management is required to change traditional practice. Septic 6. and Sewer Leakage — sewer leakage and spills are a source of pathogens and nutrients, a concern to public health, and of which many receiving water values are particularly sensitive. This issue demands particular attention in Sale's sub-catchment (1), in which the sewage infrastructure is old with spillage incidents reported at a pump station close to the Sale Canal as part of Flooding Creek. Although this issue is widespread and by no means confined to this one location, the sensitivity of this particular pump station should be communicated to the Authority being Gippsland Water, and a management plan is required.

The threat of septic leakage poses similar consequences to receiving values as does sewer leaks and spills. However, the process by which this threat occurs is generally different and must be treated as such. Many of the smaller towns in Wellington Shire are under pressure from interactions between stormwater runoff, flat grades and incapable soils, which accentuates septic leakage into receiving waters. Two key areas have sub-catchmentbeen identified through the risk assessment process of Coongulla (1) the septic leakage from which is transported to Lake Glenmaggie; and Seaspray sub-catchment (1) which is transported to Lake Reeve and the Gippsland Lakes.

Both of these towns had at one stage been ear-marked for reticulated sewage which would address much of the associated problems. At present there are no medium term plans to sewer Coongulla based on expense and perceived need. Seaspray is currently under investigation. While a government subsidised scheme for small towns has been approved, the sewering of Seaspray would still be very expensive for Gippsland Water and the decision to proceed has not yet been determined.

7.2 Management Framework - Priority Issues 1. Planning Scheme Controls — the planning scheme needs to be strengthened with more clearly outlined requirements and responsibilities, so as to provide a more enforceable statutory means of achieving Best Practise Stormwater management in planning permit conditions.

2. Internal Referrals Process — triggers for internal referrals need to be more clearly defined for issues concerning stormwater quality, including timing and responsibility for referral. Referrals also require the development of checks to provide a guide on measures required to approve developments.

3. Enforcement of Planning Conditions — continued allocation of resources is required to ensure that Best Practise Stormwater Management conditions are incorporated into developments.

4. Municipal Operations and Provision of Services — inadequate service specifications and municipal operation procedures require amendments to

EARTH TECH

D - WS SWMP Issues Paper Rev2.doc July 2002 Wellington Shire Council Stormwater Management Plan Page 19 Priority Management Issues Paper

incorporate Best Practise Stormwater Management conditions, including monitoring of activities, and training of workers.

5. Education and Awareness Programs — programs are required to train or re-train new and existing Council officers regarding their roles and responsibilities toward the incorporation of Best Practise Stormwater Management into day to day activities. Education programs are also required to target the general community, regarding inappropriate dumping into the stormwater system. Education programs are also required to target the construction industry, to raise awareness of the effects of construction runoff, and alternative Best Practise procedures.

6. Litter Enforcement — monitoring of litter "hot spots" is required, as is the allocation of resources to enforce litter laws where necessary.

7.3 Barriers and Constraints In the development of the Storm Water Management Plan there are a small number of issues that have been identified as potential barriers to the pursuit of best practice for storm water management. These issues require further investigation and development to enable a suitable strategy to be developed which will allow for the barriers to be reduced or removed. This is likely to involve a more concerted effort at a higher level (eg State Government) to overcome the problems identified.

The barriers identified are:

(1) Individual building activities not requiring a planning permit.

The risk assessments have identified that works such as building activity often contribute to a loss of water quality when storms occur and there is runoff from a building site. The building permit issued will cover the connection of the property to an approved legal point of discharge however currently does not embrace the water quality issue.

The Building Act 1993. makes no specific reference to such an issue however it does allow under Part 2, Building Standards, for the following to occur:

• Clause 7 - The Governor in Council to make regulations for the construction of buildings, or

• Clause 8 — The building regulations may empower a council to make a local law.

The Victorian Stormwater Action Program offers an opportunity to address this constraint at a state-wide level through the 'Strategic Grant' program, which is designed to address such state-wide issues in an economical and consistent manner. Currently Kingston City Council (in conjunction with eight others) is undertaking a Strategic Stormwater Project on "Improving Building & Development Practices for Stormwater Quality Protection". Outcomes from this project could be utilised in Wellington Shire.

E A A 1 T ECH

D - WS SWMP Issues Paper Rev2 doc July 2002 Wellington Shire Council Stormwater Management Plan Page 20 Priority Management Issues Paper

(2) Availability of Authority/Organization resources.

There already exists a range of legislation which provides organizations such as the EPA and municipalities with some powers to address environmental discharges including littering. The availability of organisational resources (funds and staff) however limits the capacity to deal with these matters in a pro-active manner.

(3) Presence of industrial 'as of right' use.

This right allows existing industries to discharge outside of the present requirements of new sites and best practise standards. To allow industrial land use threats to be addressed, this right to continue outdated discharge procedures need be addressed.

(4) Traditional focus towards stormwater.

The difficulty in changing community, Council and industry thinking away from designing and managing stormwater purely for quantity rather than considering water quality presents as a barrier to improvement. In many instances inadequate behaviour towards stormwater quality is due to lack of understanding of the issues, Achieving best practise for stormwater often impacts on other requirements eg. maintenance operations. An industry-wide refocus needs to be employed to overcome this barrier.

Suitable strategies to overcome these constraints are required.

8 Conclusions

A number of activities within the urban areas of the Wellington Shire have been identified to pose significant threats to stormwater quality. These adversely impact on the values of the local and regional waterways, producing an accumulating problem.

It is clear from the review of current practices that there are many opportunities to improve stormwater management and progress towards best management practices. Strategies will be developed in the Stormwater Management Plan to address the priority issues identified and improve the framework for managing stormwater quality.

E. Assessment of Management Actions Potential Actions

The Wellington Shire Stormwater Management Plan involved the development of two types of strategies to address the stormwater issues produced from the preceding work. These two types were: • Reactive Management Strategies which were to be developed to respond to current threats that relate to priority issues; and

• Management Framework Strategies, which were to be, developed to respond to identified deficiencies in the Management Framework. This section provides the worksheets used to identify the strategies to be used for the Reactive Management Strategies. The formulation of these strategies follows a process that progressively screens and evaluates a range of best practice management actions. The screening process involved reviewing a range of generic management action options which range from structural treatment measures to education and awareness, to regulation and enforcement. The evaluation process involved the calculation of an action's relative cost effectiveness score by using the formula prescribed by the CSIRO (revised 2000) Best Practise Environmental Guidelines as follows:

CapitalCost +(OngoingCost x Lifecycle) EffectiveLifecycle x%AreaTreated x Effectiveness x Fesibility x MultipleBenefit Accordingly those actions with the lower cost/effectiveness ratio were considered the more suitable approaches, and this process was used as the basis for recommended actions or groups of actions. The work sheets used in this calculation are attached below.

F. Management Strategies (Workshop 4)

Workshop 4 was carried out in one session on the 17th of May 2002 providing all Project Working Groups the opportunity to provide input into the Reactive Management and Management Framework strategies together.

These strategies were the result of the extensive community consultation as shown through the four workshops, and covered actions to address the risks to stormwater quality from land practices directly, together with actions to improve the integration of Best Practise Stormwater Management as part of Wellington Shire Council's daily planning and management activities. The top priority issues are addressed in the strategies

The recommended strategies contain a mix of approaches to address the priority issues. Educational and enforcement measures are applied which aim to minimise waste entering the drainage system from sources preventable via attitude and behavioural change. Structural measures are applied to restrict the transport of contaminants that prove difficult to be prevented from entering the drainage system. Management and planning strategies are also employed to address the day-to-day improvements, which can be made within Councils operating framework.

Central & East Sale — Sub-catchment (2) adversely affecting Lake Guthridge North & West Sale — Sub-catchment (1) adversely affecting Flooding Creek

Stormwater pollutants from residential land runoff from the above urban areas predominantly consist of gross pollutants and sediments. Gross pollutants include organic matter (ie. vegetation particularly twigs, grass clippings and leaves) as well as human derived litter (ie paper, plastic and metals). Sediments from erosion, streets, households and vegetation debris etc are a source of nutrients and toxins, which utilise sediment as the medium for transportation. These pollutants produce turbid waters and contaminated aquatic habitats. These residential land use pollutants are also the most noticeable indicator of poor water quality to the community.

Because a significant proportion of stormwater contaminates from these residential areas, are at least partially preventable by changes in behaviour, the responding strategies contain a strong educational component. Some of the educational strategies are to be applied over the entire municipality. The strategies also include structural measures, chosen to be the most effective for the pollutants to be removed, and the most feasible within the cost and site constraints.

Commercial land use stormwater pollutants in the sub-catchments above include gross pollutants, with a high percentage of human litter, dropped in and around the shopping areas. Sediments, particularly those generated from street and land degradation, buildings, and airborne particulate matter are of significant concern. These commercial areas are also a source of toxic organics, oils and surfactants, mostly transport related in terms of leaks from vehicles, car washing and poor practices in vehicle maintenance. The urban pollutants degrade the visual amenity of the receiving waters, and the health of the aquatic habitat.

The strategies in place to respond to these issues, contain a balance of educational actions aiming to prevent what is possible from entering the drainage system; and structural measures, aiming to prevent much of what enters the drainage system from being transported further into the receiving water.

Implementation of the Plan

The stormwater management plan contains a significant number of strategies and recommended management changes for Wellington Shire. There needs to be a commitment to ensure that these strategies are implemented and that protection and improvements to the valued waterways in Wellington Shire are achieved.

Responsibilities

It is anticipated that the involvement of the various organizations in developing the Plan will continue into the implementation phase. The main responsibility for implementation lies with Wellington Shire Council, but support is also required from the West Gippsland Catchment Management Authority and the Environment Protection Authority. Ongoing support from the community, as demonstrated through the Project Working Group, will be beneficial, particularly where strategies rely on commitment or input from stakeholders external to Council. The following roles are recommended for the implementation of the Stormwater Management Plan: A coordinator with the responsibility for maintaining commitment to the implementation of the stormwater management plan. It is essential that the coordinator has sufficient motivation, power/influence and funding to promote the proposed changes. It is estimated that coordinating commitments will require 20% of a senior officer's time. A committee of Council staff to oversee and review the progress of the strategies. The committee should include a number of Council staff, preferably members from each of Engineering, Planning

F - WS SWMP WS 4 Strategies.doc 15 EAR T TECH April 2002 (Environmental, Statutory and Strategic), Local Laws, Health, Building and Councillors, where possible. The committee should also contain external members such as representatives from the WGCMA, EPA and others from the current working group. It is essential that the committee receives top-down support.

Timelines and Priorities

Implementation of the reactive and management framework strategies is expected to require a period of five to ten years. This is dependent on the level of commitment allocated to the Plan in terms of funds and resources. Priorities have been proposed for the reactive strategies that respond to the priority risks identified for the receiving waters. Similarly, levels of priority have been proposed for the management framework strategies. Where strategies contain groups of action recommendations, the priority ranking is ordered to reflect their position in the implementation process. The priorities provide Council with guidance for the order of implementation.

However, it is recognised that there needs to be some flexibility to reflect the availability of funds and coordination with other activities. A number of the framework strategies would be best implemented at times when internal reviews of policies and procedures or training programs are being conducted. The reactive strategies should also allow for the full realisation of benefits of the strategies under the constraints of funding and time, taking into account the differences in the strategic approaches. For example, while it is likely that the structural protective measures will be gradually phased in over a number of years and funding budgets, the education programs should be grouped for maximum momentum for change, but continually reinforced to sustain commitment.

Therefore, it is recommended that an initial task of the implementation committee should be to develop a more detailed schedule for implementation of the strategies. This schedule could then be reviewed and updated annually in line with Council's other planning activities. For the purposes of the Stormwater Management Plan, estimates of capital and ongoing costs are considered to be indicative only. Therefore as part of the detailed schedule for implementation, a more detailed assessment of costs will be required prior to budget allocation within Council.

A review of the priorities will not be required for a number of years, given the processes involved in preparing the current plan. However, a review in three to five years time is recommended, to consider any improvements to the receiving waters, any significant changes in the extent and type of threats to stormwater quality and achievements made from the current action program. Funding

The priorities have been assigned according to their cost and effectiveness. Where possible they have considered the advantages of strategies which address multiple issues, thus minimising the cost of implementation for Council. Council however, will need to allocate a significant level of funds if the strategies are to be implemented successfully. If this is done, it will demonstrate Council's commitment to the process and may subsequently assist in obtaining additional funds from other sources. The Victorian Government has allocated $22.5 million over a three year period for improved management of stormwater quality across the State through the Victorian Stormwater Action Program. With the completion of the Wellington Shire Stormwater Management Plan, Council is in a position to apply for funds to assist in the implementation of the priority strategies identified in the plan.

Wellington Shire Council is able to apply for further funding through various government programs which are made available from time to time including:

• The Natural Heritage Trust. Commonwealth Government funds have been extended for that program which contributes to many environmental projects around the nation, generally being regional programs.

• Opportunities for school education programs may also be available through the Department of Eduction, Employment and Training under their Community Partnerships program as part of the Science in Schools strategy 1999 —2003.

Several of the strategies involve actions with overlapping responsibilities, such as water quality monitoring. Cost sharing with the Catchment Management Authority or other authorities should be pursued in these cases. In addition to the various government programs, Wellington Shire contains many large industries and businesses, a number of which themselves have some contribution to urban runoff quality degradation. Many of these industries are known for their generous support of community projects. These organizations should be pursued for partnership arrangements in the protection of Wellington Shire receiving waters.
