Environmental Audit Overlay and Contamination Constraints

Ballarat’s contamination constraint is not a single-site issue: it operates as a planning gate that affects greenfield growth at Ballarat North PSP, amendment mapping through Amendment C256ball, and urban renewal feasibility at the former Ballarat saleyards / Amendment C222ball site. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: Draft-Amendment-Ballarat-C256ball-eaoMap12-Public-Consultation.pdf; Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

The core mechanism is simple: land can be planned for sensitive uses only after contamination, landfill gas, groundwater, and adjacent industrial interface risks are understood well enough for the planning system to decide whether normal development controls are adequate, whether an environmental audit is required, or whether certain sensitive uses are not practicable. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf; Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

Background

The Ballarat North land capability assessment was prepared for the Victorian Planning Authority for the Ballarat North Precinct Structure Plan area, which the report describes as a 561 ha core area plus a 271 ha expanded area north of Cummins Road. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The land capability assessment states that the intended future land use context is primarily residential development, with supporting commercial and institutional uses, so contamination assessment is being tested against sensitive-use expectations rather than only against rural or industrial use. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The same assessment used desktop review, Lotsearch material, literature sources, and selected site inspections to identify potential soil and groundwater contamination, hydrology, groundwater, geology, geomorphology, and geotechnical constraints across the PSP area. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

Amendment C256ball includes public consultation mapping for the Environmental Audit Overlay, including one map showing EAO areas on Planning Scheme Map 12EAO and another showing areas to be deleted from the Environmental Audit Overlay on Planning Scheme Maps 12EAO and 13EAO. (Source: Draft-Amendment-Ballarat-C256ball-eaoMap12-Public-Consultation.pdf; Source: Draft-Amendment-Ballarat-C256ball-d-eaoMaps12_13-Public-Consultation.pdf)

The former Wendouree Landfill at Noble Court, Mount Rowan is a separate but connected constraint because it lies close to land being rezoned and developed through the Ballarat North PSP, and the landfill gas assessment was commissioned by the City of Ballarat to understand landfill gas impacts associated with that closed landfill. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The former Ballarat saleyards evidence in the corpus shows the same planning mechanism in an urban renewal setting: EPA told a parliamentary committee that the Ballarat site was known as a contaminated land site, that Development Victoria had commenced a detailed environmental audit using an EPA-accredited auditor, and that the proponent engages the auditor under the environmental audit scheme. (Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

Analysis

Constraint Geography and Planning Mechanism

The Ballarat North assessment does not treat the whole PSP as equally constrained; it divides the 104 assessed properties into 13 high-potential contamination properties, 11 medium-potential contamination properties, and 80 properties with no identified potential for contamination. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

This distribution matters because the planning constraint is parcel-specific: most of the PSP area can move through ordinary development due diligence, while the high and medium parcels require further screening, audit, or landfill-gas investigation before sensitive uses can be relied on. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The high-potential group is concentrated around three mechanisms: known or suspected mine-related contamination on properties 70, 71, 72, and 73; current asphalt services use on property 77; and the inferred former Wendouree Tip extent across properties 90, 91, 92, 98, 99, 100, 101, and 102. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The medium-potential group is more diffuse and includes possible stock dip, imported fill, spoil mounds, metal scraps, downgradient exposure from high-potential parcels, adjacency to the former Wendouree Tip, and land affected by existing EAO mapping. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The Jacobs recommendation applies Planning Practice Note 30 logic: medium-potential properties should complete a Preliminary Risk Screen Assessment to determine whether an environmental audit is needed, while high-potential properties may proceed directly to environmental audit. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The practical effect is that contamination is not only a technical risk; it becomes a sequencing control because development permits, subdivision design, and sensitive-use assumptions may depend on whether PRSA, audit, remediation, capping, or land-use exclusion is required. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

Environmental Audit Overlay Mapping

The C256ball EAO map shows Environmental Audit Overlay land in the Wendouree, Miners Rest, and Mount Rowan area around Olliers Road, Noble Court, Gillies Road, Midland Highway, and the Western Freeway. (Source: Draft-Amendment-Ballarat-C256ball-eaoMap12-Public-Consultation.pdf)

The C256ball deletion map shows an area to be deleted from an Environmental Audit Overlay in the Wendouree and Mount Rowan area, with the map referencing Planning Scheme Maps 12EAO and 13EAO. (Source: Draft-Amendment-Ballarat-C256ball-d-eaoMaps12_13-Public-Consultation.pdf)

The Jacobs assessment explains the likely reason for partial deletion: the historical EAO remains over property 74 and parts of properties 75 and 97, but Jacobs records an understanding that the activities giving rise to the original EAO did not occur on properties 75 and 97. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

That mechanism is important because an EAO boundary can be over-inclusive if the mapped control follows a historical title or broad area rather than the actual location of the contaminating activity. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: Draft-Amendment-Ballarat-C256ball-d-eaoMaps12_13-Public-Consultation.pdf)

The risk of over-correction is that deleting an EAO from land that is not the source of contamination may still leave downgradient, groundwater, creek, or landfill-gas pathways requiring separate assessment if later evidence shows exposure pathways extend beyond the original activity area. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Former Wendouree Tip and Landfill Gas

The former Wendouree Landfill is the strongest contamination constraint in the available corpus because it combines uncertain waste extent, continuing gas generation, shallow groundwater, Burrumbeet Creek, and proposed sensitive receptors in the PSP area. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Landserv records the landfill as Lot 1 on TP846568 at Noble Court, Mount Rowan, and states that it accepted municipal solid waste between 1968 and 1983 before being closed and capped around 1983. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The same report also cites Victorian Landfill Register information listing the site as landfill register number 10038, with closed operating status, putrescible waste and solid inert waste accepted, estimated closure in 1983, and historical licence number HS000542/3. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The PSI information summarised by Landserv indicates that capping commenced by 1990 and was completed by 2010, that the inferred waste extent may extend beneath the Western Freeway road reserve, and that filling did not occur east and north of Burrumbeet Creek. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Landserv states that no information is available on landfill base lining and that, given the age of the landfill, it is considered unlikely the site was lined. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The landfill gas assessment records that historical monitoring from a leachate bore showed the landfill is still producing methane and carbon dioxide. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

SMEC monitoring cited in Landserv recorded methane in leachate bore LB2 at 84.4 percent v/v in August 2023, 73.1 percent v/v in March 2024, and 73.4 percent v/v in August 2024. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

SMEC monitoring cited in Landserv recorded carbon dioxide in leachate bore LB2 at 12.9 percent v/v in August 2023, 12.2 percent v/v in March 2024, and 11.4 percent v/v in August 2024. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Landserv installed five landfill-gas bores: GB1 to GB3 south of Burrumbeet Creek, GB4 north of Burrumbeet Creek, and GB5 as a replacement north of Burrumbeet Creek after GB4 was affected by shallow groundwater ingress. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The adopted interpretive action levels were 1.0 percent v/v methane and 1.5 percent v/v carbon dioxide above background for subsurface geology at the landfill boundary. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Discrete monitoring over five events did not record methane above the 1.0 percent v/v action level, but it did record 13 exceedances of the 1.5 percent carbon dioxide action level and limited to negligible flow rates. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Continuous monitoring recorded methane concentrations of 0 to 1.8 percent v/v in GB1 to GB3 and 0 to 1.6 percent v/v in GB5, meaning some continuous readings exceeded the adopted methane action level. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Continuous monitoring recorded carbon dioxide of 2.7 to 6.6 percent v/v in GB1 to GB3 and 0.1 to 0.9 percent v/v in GB5, meaning carbon dioxide exceedances were concentrated south of Burrumbeet Creek in the installed monitoring network. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The conceptual site model identifies three pathways: vertical landfill gas migration through fissures and cracked cap areas, horizontal migration through fissures and subsurface pore spaces, and partitioning of dissolved methane in groundwater to soil gas. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Burrumbeet Creek may be acting as a barrier to lateral landfill gas migration north of the creek because shallow groundwater and saturation of the subsurface profile may limit lateral gas movement. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

That possible creek barrier should not be treated as a resolved planning conclusion because Landserv states that further wells, further groundwater and gas monitoring, pathway analysis of dissolved methane in groundwater, assessment of PSP effects on local water table levels, and delineation of the inferred waste boundary are required to understand current and future receptor risks. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Parcel-by-Parcel Implications for Ballarat North PSP

Jacobs recommends a landfill gas risk assessment for the inferred former Wendouree Tip parcels 90, 91, 92, 98, 99, 100, 101, and 102. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

Jacobs also recommends that landfill-gas risk be considered for all parcels within the estimated 500 m landfill buffer, specifically parcels 62, 63, 64, 65, 66, 67, 68, 69, 70, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 93, 94, 95, 96, 103, and 104. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The practical planning effect is that even parcels with no direct soil-contamination indicators may still require landfill-gas assessment if they sit within the 500 m landfill buffer. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

Jacobs states that the former Wendouree Tip is the likely exception to the broader conclusion that contamination does not appear to create significant constraints rendering land unsuitable for future sensitive land use. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

This means the PSP should not assume uniform residential capacity over the former landfill footprint until landfill-gas, leachate, groundwater, cap integrity, and waste-boundary questions are resolved. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Groundwater and Soil Interaction

Groundwater is a critical pathway because Jacobs identifies shallow groundwater across large parts of the precinct, potential groundwater inflow to excavations, possible waterlogging, and the need for site-specific groundwater impact assessments near groundwater receptors. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

Landserv records groundwater at less than 5 m below ground level in the north to north-east part of the former landfill site and records an August 2023 standing water level of 1.175 m below ground level at GW2 between the landfill and Burrumbeet Creek. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The combined planning issue is that earthworks, drainage design, dewatering, and service trenches can alter groundwater conditions, which in turn may affect landfill gas movement, leachate behaviour, groundwater receptors, and construction management requirements. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Jacobs also identifies dispersive and reactive soils across the study area, with subsoils susceptible to erosion when topsoil is removed or when drainage works expose dispersive material to runoff. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The contamination relevance of dispersive soils is indirect but material: unstable or erodible earthworks can complicate cap integrity, drainage stability, sediment movement, unexpected-finds management, and the physical reliability of any containment strategy.

Former Ballarat Saleyards as a Parallel Urban Renewal Constraint

The former Ballarat saleyards evidence is not the same site as the Ballarat North PSP evidence, but it is relevant because it demonstrates how contamination can control the transition from legacy land use to sensitive use in Ballarat. (Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

EPA told the 2026 Commonwealth Games Bid Select Committee on 13 October 2023 that the Ballarat site was known as a contaminated land site and had former livestock saleyard use, associated animal storage areas, a rail corridor, possible historical mining activity, and potential sources including herbicides, pesticides, hydrocarbons, organic waste, and heavy metals. (Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

EPA also told the committee that Development Victoria had commenced a detailed environmental audit using an EPA-accredited environmental auditor, and that the audit was the process for identifying particular issues and approaches to reduce risks. (Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

EPA distinguished temporary village use from ongoing residential use: it was generally supportive of temporary accommodation for the limited games period, but it was not prepared, on the information available at the time, to support ongoing residential use because further assessment of odour and noise risks from surrounding industrial activities was required. (Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

The Courier article metadata from 4 July 2023 describes concerns about soil remediation at Ballarat’s old saleyards site and questions about decontamination work for the athletes’ village before the 2026 Commonwealth Games. (Source: web-research-L1-c222ball-contamination-concerns-the-courier.txt)

The Courier article metadata from 20 September 2025 states that remediation at Ballarat’s historic saleyards on Latrobe Street was expected to begin in late 2025 and described the intended transition toward business and housing uses. (Source: web-research-L1-c222ball-remediation-2025-the-courier.txt)

The saleyards evidence should be treated cautiously because the available Courier extracts are mostly metadata and schema text rather than full article text. (Source: web-research-L1-c222ball-contamination-concerns-the-courier.txt; Source: web-research-L1-c222ball-remediation-2025-the-courier.txt)

Current Status

The Ballarat North contamination evidence is at investigation and amendment-support stage, with Jacobs recommending PRSA, environmental audit, landfill-gas assessment, CEMP controls, groundwater investigation, geotechnical investigation, and soil characterisation before development decisions rely on sensitive-use assumptions. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The landfill-gas evidence has advanced beyond desktop assessment because Landserv installed and monitored landfill-gas bores in October and November 2024, but Landserv concludes that further wells, further monitoring, dissolved methane pathway analysis, PSP water-table impact assessment, and landfill waste-boundary delineation are still required. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

Amendment C256ball includes public consultation EAO mapping dated 16 October 2024 for Map 12EAO and public consultation D-EAO mapping dated 28 October 2024 for Maps 12EAO and 13EAO. (Source: Draft-Amendment-Ballarat-C256ball-eaoMap12-Public-Consultation.pdf; Source: Draft-Amendment-Ballarat-C256ball-d-eaoMaps12_13-Public-Consultation.pdf)

The former saleyards contamination pathway remained unresolved in the parliamentary evidence because EPA stated on 13 October 2023 that the environmental audit was underway and that Development Victoria was best placed to confirm its progress. (Source: web-research-L1-c222ball-environmental-audit-epa-parliament-transcript.txt)

EPA Victoria is a central state-agency actor because EPA reviewed the Jacobs land capability material in 2024 and recommended that the LCA consider landfill gas migration from the former Wendouree Landfill and the buffer-distance requirements of EPA Publication 1642 and draft EPA Publication 1950. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The Victorian Planning Authority is a central PSP actor because the Ballarat North PSP and Development Contributions Plan are being prepared by VPA in collaboration with the City of Ballarat. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The City of Ballarat is both planning authority and land-risk manager in the former Wendouree Landfill evidence because Council owns and manages the landfill site and commissioned the landfill-gas assessment to fulfil its general environmental duty as responsible authority.

Gaps in This Analysis

The corpus does not include completed PRSA reports for the Ballarat North medium-potential parcels, so this page cannot state whether any of those parcels have progressed to environmental audit or been cleared for sensitive use. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The corpus does not include completed environmental audit statements for high-potential parcels 70, 71, 72, 73, 77, 90, 91, 92, 98, 99, 100, 101, or 102, so this page cannot state final suitability, remediation requirements, or residual management conditions for those parcels. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf)

The corpus does not include the full Ballarat North PSP, DCP, land-use budget, or staging plan, so this page cannot quantify lot-yield effects, infrastructure-cost effects, or development-stage triggers arising from contamination constraints. (Source: Ballarat-North-PSP-Land-Capability-Assessment-Jacobs-October-2024_Part-1-of-2.pdf; Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The corpus does not include the Adverse Amenity Impact Assessment that Landserv says GHD prepared and that was under review, so this page cannot integrate odour, dust, noise, or industrial-interface constraints with contamination and landfill-gas constraints. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The corpus does not include the Senversa 2021 PSI, SMEC 2024 bore installation report, SMEC 2024 landfill gas monitoring reports, or SMEC 2024 landfill water monitoring report, so this page relies on Landserv’s summaries of those documents rather than the primary technical datasets. (Source: Ballarat-North-PSP-Landfill-Gas-Assessment-Landserv-April-2025.pdf)

The C256ball map extracts show EAO and D-EAO geography but do not provide parcel-by-parcel legal descriptions or area measurements, so this page cannot calculate the number of hectares added to or removed from the Environmental Audit Overlay.
