Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans Acknowledgements The Mallee Catchment Management Authority (CMA) wishes to acknowledge the contribution of agencies involved in the development of this document, including: • Parks Victoria • Department of Sustainability and Environment (DSE) • Department of Primary Industries (DPI) • Lower Murray Water (LMW) The Authority also acknowledges: • the work of Sunraysia Environmental in providing technical content; and • developers who willingly made previous Site Environmental Management Plans (SEMPs) available for reference in the development of this document.


Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans 1.0 Introduction to SEMP and the Standards 1.1

Purpose of Site Environmental Management Plans (SEMP)

The objective of a Site Environmental Management Plan (SEMP) is to protect river frontage and demonstrate that public safety, aesthetics, cultural values and water resource values have been addressed as part of a proposal to construct water diversion infrastructure. Where possible, efforts should be made to enhance the environment in the vicinity of the proposed infrastructure. The purpose of a SEMP is to ensure that the natural features of the proposed site, such as land stability, existing vegetation, native animals, water courses and social values of the site, are identified early in the planning phase. These matters must be duly considered when selecting the location, design and construction methods of the proposed water diversion infrastructure works. As all Murray River frontage in the Victorian Mallee is Crown (public) land, a SEMP must be completed to obtain the consent of public land managers prior to: •

construction of new water diversion infrastructure;

adding capacity to existing water diversion infrastructure;

decommissioning major structures.

Public Land Manager’s Consent must be obtained before a Planning Permit can be issued by local government (e.g. Mildura Rural City Council) and before Lower Murray Water (LMW) will issue a Works Licence to construct, alter, remove or decommission pumps and pipelines. The proponent should also investigate the need for other approvals (refer to Appendix 1). Once a SEMP is compelted by the developer, it will be assessed by the Department of Sustainability and Environment (DSE) to determine if the site is suitable for occupation and what actions must be taken to minimise the potential environmental impacts at the nominated site. A SEMP must cover the following areas: •

applicant details;

proposed works;

natural features of the location (assets) and condition ;

potential impacts (threats) posed by the proposed infrastructure placement and construction activities;

1


Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans •

mitigation measures that will be undertaken to avoid or minimise impacts, along with information outling how any damage or disturbance will be compensated for through preservation, restoration or rehabilitation activities;

1.2

site management and supervision;

monitoring and reporting.

Purpose of this document

The objective of this Standards for SEMPs document (“standards document”) is to provide a practical guide for those seeking Public Land Manager’s (PLM) consent to construct water diversion infrastructure on public land in the Victorian Mallee. This document is a guide to the structure and content of the reports that may be required to be submitted by proponents to inform the consent process. The standards outlined in this document describe the minimum requirements (Key Performance Indicators; refer Appendix 2) that DSE will use to determine if the natural features on the public land will be protected and preserved during construction works and into the future.

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans Who will use this document and how? This document is intended to be used by irrigation developers and/or their consultants/ agents to compile the supporting documentation for an application for PLM consent required to construct water diversion infrastructure. Proponents should discuss their intentions with the Department of Primary Industries (DPI) Mallee Irrigation Development Coordinator prior to using this document and seek advice on the relevant sections in this document that will need to be addressed. This document will also assist DSE staff in the assessment of SEMPs by providing a benchmark for the scope and content of the documentation required to support an application for PLM consent. What does this document include? Section 2 of this document mirrors the headings included in a SEMP, with details provided under each heading outlining what information should be considered. Section 3 guides proponents through the range of techinical information that must be considered when planning the proposed works and preparing a SEMP, in order to characterise the environmental values of the site and potential risks posed by the proposed development. This information may be gathered through a variety of methods including desktop studies, site assessments, and relevant techinical investigations. The information gathered in Section 3 is used to develop design and construction methods that will protect and preserve the natural assets identified. These methods underpin the management plans detailed in Section 2.

1.3

Context within the New Irrigation Development Framework

Under the Victorian Water Act 1989 , the Draft Victorian Mallee New Irrigation Development Guidelines (the Guidelines) have been developed to outline the regulatory framework (Agencies, Acts, Regulations Policies and Processes) relating to new irrigation development. PLM consent is one of the required processes within this framework. This standards document complements the Guidelines in that it provides the higher level of detail required to prepare a SEMP for PLM consent. Within the PLM consent process, Siting and Design Guidelines (NRE 2001) exist to

3


Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans guide design and construction of water diversion infrastructure. The Siting and Design Guidelines must be met by all water diversion infrastructure developments. This standards document doesn’t replace the Siting and Design Guidelines, but outlines the requirements that must be met by proponents of complex and more sophisticated construction works. This standards document captures the learnings from the last decade, of rapid expansion in the Victorian Mallee irrigated horticultural industry. Much of the information in a SEMP may also be relevant to applying for a Works Licence; however, there are some additional specific details required by LMW that are not included in a SEMP. Consultation is required with LMW in relation to the following areas not addressed within this document: •

infrastructure design specifications including cross sections, technical features and surveys of waterways;

metering requirements;

private storage dam requirements;

operation and maintenance plan for the pump site.

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans 2.0 SEMP Report Outline This section provides the headings that should be included in a SEMP, with details provided under each heading outlining what information should be considered. This information is gathered from detailed site assessments and investigations (refer to Section 3). In developing a SEMP, proponents should note that the characteristics at each proposed work site will vary and therefore the level of information required will also vary. While this section (Section 2) contains a comprehensive list of matters that should be considered in the development of a SEMP, not all matters will be applicable for all developments. Proponents should seek early advice on their plans by speaking to the Mallee New Irrigation Development Co-ordinator at the Department of Primary Industries (DPI).

Figure 3: A potential pump site which is acceptable against most criteria may be too close to the river bend, with a high likelihood of undercutting of the riverbank in the long term. Navigation hazards may also be a factor. Photo: Sunraysia Environmental Pty Ltd.

Proponent details

A SEMP must include the name, address and contact details of the legal entity that will own and operate the infrastructure and the details of the person/entity who will hold the relevant licence. If the approvals application process is to be undertaken by an agent on behalf of the legal owner, then the agent’s name and contact details must also be provided as the primary contact person.

2.2

Proposed infrastructure and site selection

In preparing a SEMP, information is required on the type of infrastructure proposed and why the nominated site was chosen for both the pumps and rising mains route. Alternative options that have been considered, but subsequently ruled out, should also be described to demonstrate that the nominated route is the best option to minimise impact on the environment and social values. An example of a location map illustrating the proposed pipeline route in relation to the property is outlined in Appendix 4. 2.2.1

Description of proposed infrastructure

In order to minimise the visual impact of a pump station and ensure it does not detract from the aesthetics of the river frontage, it is expected that: •

pump size and associated infrastructure does not exceed property requirements;

pump houses and other buildings (e.g. electrical cabinets) are as small as practical, while complying with the requirements of the relevant engineering regulations and standards;

pump sites and access tracks are consolidated where possible;

existing works, access tracks and power lines are utilised;

all power supply on the river frontage, manifolds and rising mains will be installed underground, while complying with the requirements of the relevant engineering and electrical regulations and standards;

the infrastructure be coloured to be compatible with the surrounding environment;

native vegetation be utilised to screen the infrastructure from the river and river bank;

the height and profile of structures be minimised where possible by considering a number of smaller capacity pumps;

only essential components of water diversion infrastructure are located on the river frontage.

A site plan (refer to example in Appendix 5) of the proposed infrastructure should be

6


Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans prepared that clearly identifies: •

the number of pumps and pipelines required to service the property, including location of air valves, bypass pipes, electrical cabinets and cabling, fencing, etc;

the location of trees (alive and dead) or large shrubs in the construction zone (centre point of trunk and outline of foliage);

the power supply from grid to pump site;

land features (e.g. floodways, existing infrastructure);

road reserves, neighbouring property boundaries, the river bank.

A side view and plan of the proposed infrastructure should be prepared as outline drawings to clearly identify: •

the height of infrastructure relative to river bank, surrounds and flood levels (300mm above the 100 year ARI flood level);

the cross-section of pipeline trenches/pipes and backfill materials.

discussion on other site options considered during the process of determining the preferred site.

Aside from environmental impacts, there are other factors that may influence the choice of a pump site/pipeline route and footprint. While such factors may affect a SEMP, they are not part of the Public Land Manager’s Consent process. A brief description of how each factor was considered in the process of determining the preferred site needs to be included in the SEMP. Factors commonly considered include: •

proximity of site to the proposed irrigated area;

limitations posed by crossing a Category 1 road reserve (VicRoads road);

capacity of other road reserves;

barriers posed by adjoining irrigated land or intensively settled areas;

potential impacts on waterway navigation;

pipeline routes through neighbouring private land using easements rather than through public land (apart from the river frontage, which in the case of diversion from the river is unavoidable);

presence of European or Aboriginal cultural heritage.

2.3.3

Zones and Overlays

The Zones and Overlays under the Municipal Planning Scheme that relate to the proposed development should be identified and the implications summarised in a SEMP. For example, a proposed development could be planned for an area where a historic structure is listed on the Heritage Overlay relating to the river frontage. This listing be will provide the structure with protection and possibly apply a buffer zone or other conditions to any works in the vicinity. The Municipal Planning Scheme needs to be reviewed in respect to the development, early in the process, as planning provisions may prevent a proposed development or impose stringent conditions at some locations. The need for a planning permit should be discussed with the relevant municipal body and should be clarified in a SEMP, with reference to the relevant provisions in the planning scheme. 2.3.4

Local sites of environmental significance

The proximity (in metres or kilometres) of the proposed construction site to sites of national or international significance and any wetlands and conservation reserves must be identified in a SEMP.

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans 2.3.6

Current Land Use

How often the site is visited and how it is accessed by the general public will determine the sites exposure and the potential public safety issues that may need to be considered during construction works. The current use of the river frontage and pipeline route should be described and may include the following: •

tourism, recreation, access routes, public utilities (e.g. power lines), other water diversion infrastructure, fences;

proximity of site to residential dwellings and places used by people;

description of the landuse on neighbouring private land.

2.3.7 Biodiversity A brief description of the key native vegetation and fauna that visit the sites must be described in order to determine the environmental value of the natural features. This is likely to require specialist advice in native flora and fauna to undertake technical assessments (refer to Sections 3.1 and 3.2).

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans 2.4

Defining the construction zone and the extent of disturbance

The extent of the area disturbed by construction operations will need to be identified, including access tracks leading to the pump site. The minimum width required for the pipe trenching and maximum width for the pipe laying operation should be clearly illustrated. The airspace above the ground and site access must also be considered in the construction zone (e.g. overhanging tree branches on access tracks may constrain the use of cranes to install pumps). Areas subject to differing levels of disturbance are best defined in a map (Appendix 4) showing: construction zone, work zone, traffic zone, conservation zone and rehabilitation zone. The map should show the location of defined zones in relation to the proposed infrastructure and key environmental features. An explanation of the key features to be illustrated in each zone is provided in Appendix 3.

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans 2.5

Construction management

The construction activities should be clearly described, including how they have been developed to avoid and minimise impacts on the environment and the social values at the preferred site. Construction methods will need to be suited to working in confined areas. Machinery will need to be able to manoeuvre safely around stockpile and storage areas within the construction zone. 2.5.1

Site establishment plan

A site establishment plan should be developed to avoid and minimise impacts on the environment. An establishment plan may include: •

How the zones will be marked on the ground and maintained. Zone protection measures could involve: fencing, bunting, flagging tape, bollards and signage. In areas of high vegetation value, a more permanent fence may be required to prevent machinery and stockpiles breaching the zone. Areas that have rigid fencing may enable greater flexibility for construction by providing a physical barrier to prevent native animals and the general public from entering the construction zone;

Figure 9: Use of a skip for rubbish containment during construction is essential on a large project. Note: construction materials are stored in the construction zone. Photo: Sunraysia Environmental Pty Ltd.

14


Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans •

How native vegetation will be marked for removal (X) or trimming (T) onground (e.g. using white paint or flagging tape on-ground); as well as the construction zone map;

Specific Hold Points where the authorities will inspect the site and approve the continuation of the works (e.g. marking of zones, marking of pipeline route, practical completion etc). This creates an opportunity to correct or realign works that do not reflect the original plan;

Plans for rubbish and waste management, storage, removal. Rubbish must be contained on site at all times and not allowed to migrate out of the construction zone. An industrial skip may be allowed for larger sites but must be located at least 100m from the river bank or at an off-site location;

Procedures for the management of hazardous materials to ensure there will be no spillage and therefore no contamination of the soil, water or air;

Provision of staff amenities. One portable toilet and one office may be allowed to be located at least 100m from the river bank or at an off-site location. Information provided should also include a description of the type of toilet and how it will be maintained;

Arrangements for the decommissioning and removal of old/redundant infrastructure (e.g. pump station, levy banks or channels). Requirements for decommissioning may be determined through a heritage assessment or soil contamination investigation. Decommissioned and disused infrastructure that does not have any aesthetic or historic value must be removed from the site within 30 days of the infrastructure becoming redundant;

Plans for investigations of contaminated sites and amelioration or removal of contaminated soil that exists at the site, which must be undertaken in accordance with relevant legislation prior to commencing works;

Details on how public safety will be managed, including signs, fencing and provision of alternative access tracks around the site;

How the site establishment plan will be communicated to all contractors and subcontractors on site.

Site management

A SEMP should also include a specific site management plan to ensure that a management structure is in place to supervise contractors during works; to report on SEMP non-compliances; and to ensure that corrective actions are implemented immediately. A site management plan should include: •

The relevant project management structure;

The name of the nominated site supervisor and contact details;

Details of contract and sub-contract staff inductions and works briefings.

SEMP incident (accidental damage) report and notification procedures.

An incident and emergency response plan (e.g. flood/fire).

Notification protocols for when hold points are reached and works are completed.

2.7

The schedule of works.

Monitoring requirements and reporting schedule

A monitoring plan is required to be developed before works commence, along with the establishment of permanent photographic monitoring reference points (i.e. a permanent marker from which photo point monitoring can be conducted before, during and after construction). These will be used to illustrate compliance to the SEMP report. The monitoring plan must detail monitoring activities to be undertaken during the construction phase, rehabilitation phase and post-construction. Monitoring provides the evidence to demonstrate to the public land manager that the proponent has carried out works in line with the original SEMP and that ongoing maintenance of the site is being undertaken. Key Performance Indicators are used by DSE to determine if the environmental assets at a site are being protected and preserved (refer Appendix 2). The proponent should identify in the monitoring plan which KPIs are relevant to their proposal. The monitoring plan should include a reporting schedule. The frequency of monitoring and reporting during construction should reflect the scale, degree of risk and duration of the works. For example, the monitoring of a large development may need to be done quarterly during construction or may align with the completion of major stages in construction (e.g. pipeline trenching). Monitoring post construction may only be required annually for up to three years. Each reporting event nominated should include a brief report to DSE addressing the KPIs.

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans 3.0 Detailed assessments required to inform a SEMP Various investigations and assessments must be undertaken at a site to characterise the environmental values of the site and the potential risks to those values posed by the planned new infrastructure and associated construction works. Such investigations should also address practical ways to minimise risks to the environmental values of a site during design and construction works. The information from these investigations and assessments may help complete the management plans outlined in Section 2 of this standards document. When submitting a SEMP, the detailed reports of assessments and investigations carried out should be attached as appendices in order for the assessors to understand the reasoning behind the approach described in the SEMP. These assessments will require specific technical expertise and suitably qualified assessors to ensure the information is accurate and the logic is sound. Early discussions with the Mallee New Irrigation Development Co-ordinator will assist in determining which assessments are relevant for the nominated site. For all assessments, the area that needs to be investigated should include the construction zone, plus approximately 50m either side.

3.1

Native vegetation assessment and management plan

Native vegetation assessment and management plans must be consistent with Victoria’s Native Vegetation Management - A Framework for Action (NRE 2002). A native vegetation assessment will identify the type of vegetation located at the proposed site, or in the near vicinity and the environmental value of this vegetation. A vegetation assessment may include the following: •

Identification of bioregions and Ecological Vegetation Classes (EVCs) from modelled EVC mapping, including a comment on the connectivity of existing vegetation stands.

A list of flora species that may occur in this area from a database search; Victorian Rare or Threatened Species (VROTS) should be highlighted.

Verification of the flora species found to be growing in the local area and the EVC through a field inspection.

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans A fauna management plan may include the following: •

Measures to protect fauna during construction (e.g. inspection of trenches each morning for fauna, inspection of open pipes for fauna prior to use, closing off installed pipe ends overnight, wildlife rescue and relocation procedures);

Erection of semi-permanent fencing around work areas to prevent animals falling into open trenches.

Consideration of the timing of works to avoid mating or breeding seasons.

Identification of pest animals at the site and how they may impact on the development and rehabilitation activities. Impacts on wildlife must be avoided during pest animal control.

3.3

Hydrology and geotechnical assessment

A hydrology report relates to assessment of the impact of proposed structures on water flows, particularly during floods. A geotechnical assessment will identify the potential for soil erosion, soil and by default, riverbank stability issues. These assessments will inform suitable placement of pumps, pipelines and associated infrastructure (refer Section 2.3.5). A hydrology assessment may be required for developments where the proposed pump station infrastructure is large and may cause obstruction to water flows in high river events. A geotechnical assessment may be required wherever there is potential for soil instability or soil erosion, particularly during floods and large rain events. It may also include design considerations for infrastructure foundations, supports and anchor points.

Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans 5.0 Glossary of Terms and Acronyms AHD: Australian Height Datum, used for describing the absolute height at a point of land. Biodiversity: the variety of all life forms- the different plants, animals and microorganisms, the genes they contain and the ecosystems of which they are a part. Bioregions: biogeographic areas that capture the patterns of ecological characteristics in the landscape, providing a natural framework for recognising and responding to biodiversity values. Crown Licence: for most categories of public land DSE may issue a Crown licence (with conditions) to allow occupation of that land by infrastructure or other uses. A licence is issued for a specified period and is periodically reviewed. However a Crown licence for water diversion infrastructure on the Murray River frontage is no longer issued. Dangerous tree: a tree that poses an immediate threat to life and property. Database search: provides a list of flora and fauna that have been recorded in a geographical area and their conservation status. When requesting a search, a buffer zone is usually added to a study area to expand the search area to obtain meaningful data. DBH: diameter at breast height, a standard method of defining tree size/age. Department of Primary Industry: case manager for irrigation development proposals, responsible authority for pest plants and animals. Department of Sustainability and Environment: (DSE) administers the occupation of public land and issues Public Land Manager’s Consent to apply for a planning permit. DSE is a referral agency for planning applications and is the responsible authority for flora and fauna and removal of native vegetation. Ecological Vegetation Class (EVC): a type of native vegetation classification that is described through a combination of its floristic, life form and ecological characteristics. EPBC: matters of national environmental significance or other matters protected by the Environment Protection and Biodiversity Conservation Act 1999.

34


Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans Habitat hectare: a site-based measure of quality and quantity of native vegetation assessed in the context of a specific Ecological Vegetation Class (EVC). A site assessment is done by comparing vegetation quality to a defined benchmark for each EVC. Habitat tree: usually a large old tree that contains habitat for fauna e.g. decorticating bark, hollows and forks or tall branches suitable for nesting. Land tenure: is the person or entity who owns and/or manages a parcel of land; the generic descriptors of public land and private land is one way of describing land tenure, the next level is who is the owner/manager/occupier. Local Government: A Council is the responsible authority for administering its planning scheme and considering applications for planning permits. Lower Murray Water: the responsible authority for much of the Water Act 1989. May issue a Works Licence for proposed water diversion infrastructure on the Murray River frontage. Murray River Public Purposes Reserve: the strip of Public land comprising the river frontage on the Victorian side of the Murray River. The reserve is generally 60m in width but is much wider in some locations and may be occupied for various uses under a licence or lease. Water diversion infrastructure is commonly located on the reserve, which is in the process of being re-classified as the Murray River Park which will not impact on its availability for approved water diversions. Mitigation measures: actions that are taken that will minimise or avoid impacts of the development on the environment. Net gain: a measured increase in the extent and/ or quality of native vegetation. NSW Victoria State border: the boundary between the States as surveyed in 1870 generally then along the high bank on the Victorian side of the Murray River. Offset: the gain in native vegetation quality and/or extent required under a habitat hectare assessment to compensate for losses incurred due to destruction, removal or lopping of native vegetation.

35


Victorian Mallee Irrigation Region Standards for Site Environmental Management Plans Overlays: (relates to a planning scheme), ensure that important aspects of the land are recognised (such as areas of significant vegetation or special heritage significance). Overlays indicate the type of development and/or protection which may be appropriate in that area, e.g. heritage overlay, environmental significance overlay. Parks Victoria: manages reserved Public land on behalf of DSE, including the Murray River Park. Planning permit: a legal document that allows a certain use or development to proceed on a specified parcel of land. A permit is not always required to use or develop land. Planning scheme: a legal instrument, that sets out the provisions for land use, development, and protection, it’s function is to facilitate fair, orderly, economic and sustainable use of land - by providing for the individual needs of an area. A planning scheme is administered by the relevant Council. One way they do this is by requiring that certain types of use or development can only be carried out if a planning permit is granted. Planning schemes allow some changes in land use without the need for a permit, provided conditions are met. Some uses or development may be prohibited. Public Land Manager’s Consent: consent must be obtained from DSE to build and operate structures on public land. In addition, consent must be obtained from the Public Land Manager prior to submitting a planning application for certain developments on public land. Proponent: the legal entity that is proposing to build and own the water diversion infrastructure, that is the entity seeking Public Land Manager’s Consent. Threatened species: The Flora and Fauna Guarantee Act 1988 (Vic) provides for the listing of genera, species, subspecies, varieties and communities of flora and fauna which are threatened (the Threatened List), and potentially threatening processes (the Processes List). There are also species that are listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. Threatened species are protected under the legislation and some may have an action plan. Three step approach: relates to the way environmental impacts are addressed in planning and implementation of works that involve disturbance: •

Avoid adverse impacts, particularly native vegetation clearance

36

If impacts cannot be avoided, minimise impacts through appropriate consideration in planning processes and expert input into project design or management

Identify appropriate offset options.

VROTS: Victorian Rare or Threatened Species, an advisory list of flora and fauna that are categorised according to the parameters - extinct, endangered, vulnerable, threatened, rare or poorly known in Victoria. Zones: areas assigned on a construction site based on environmental values and needs of construction: •

Work zone - total area impacted including construction zone, access tracks, materials storage, stockpile sites, vehicle and equipment parking, amenities, skip, maintenance and refuelling;

Traffic zones - access tracks or roads through or near the work zone where there will be public use;

Construction zone - areas or area directly impacted by works, includes pump footprint, transformer kiosk, control room and, power supply and pipeline corridor. No works to be performed outside this zone;

Work exclusion zone - area within a work zone that maybe excluded due to vegetation or other reasons, not to be disturbed. Could be a single tree, archaeological site, etc;

Conservation zone - area outside the work zone, construction zone and traffic zone, not to be disturbed;

Rehabilitation zone - area involved in restoration of the site including provision of offset revegetation;

Storage area - designated area storing for overburden during construction, pipe, and other materials prior to installation, will be within the work zone.

Zones: relating to a planning scheme, reflect the primary character of land and indicate the type of use and development which may be appropriate in that zone, e.g. residential zone, public conservation and resource use zone, road zone or farming zone.
