Blade Removal, Processing & Incident Record
This page preserves the available documentary record concerning 2024 turbine-blade removal and processing activity, including later laboratory analysis of associated processing powder, and the separate 2026 Y23 blade-failure incident, including later site footage, debris condition, rainfall context and proximity to Lal Lal Reservoir.
What this page records
The page contains two distinct documentary records: the 2024 blade-removal and processing record, now including additional laboratory analysis concerning associated processing powder, and the 2026 Y23 blade-failure/site-condition record. The material records what was observed, communicated, tested and later photographed or filmed. It does not by itself establish pollution, contamination of a waterway, or a regulatory finding.
The July correspondence predates the establishment of the Owen Robert Inter Vivos Trust and is therefore identified as part of the historical Beneficiary administrative record. EPA South West Region was copied into that email chain. That fact records contemporaneous awareness of the enquiry; it is not presented as EPA endorsement of the operator’s response.
Y23 — site condition 104 days after the 15 May 2026 incident
The operator recorded a blade failure at turbine Y23 at the Yendon Wind Farm at approximately 6:45 am on 15 May 2026. New third-party footage supplied to the Beneficiary on 27 August 2026 provides a later visual record of the incident area.
104 days elapsed
From 15 May to 27 August 2026, 104 days elapsed. The 27 August footage shows substantial blade sections and numerous smaller fragments still visible across the incident area.
Visible site condition
Compared with the earlier May footage, no material general clean-up or recovery of the dispersed debris is apparent from the later visual record. This is a visual comparison only and does not establish that no material whatsoever had been removed during the intervening period.
Rainfall exposure
Available Lal Lal locality rainfall records indicate approximately 200 mm of rainfall over the intervening period, including a significant rainfall event of approximately 42 mm on 10 August 2026. The cumulative figure is presented as an approximate locality estimate, not a site-specific rainfall measurement.
Later visual record of the Y23 incident area
The footage is approximately 65 seconds long and records the turbine base, substantial blade sections and dispersed smaller fragments across the surrounding ground. The footage is preserved as received from the third party.
Reservoir proximity and rainfall
Lal Lal Reservoir is approximately 2.5 km from Y23 on the supplied straight-line map. The incident material therefore remained visible through a period of repeated winter rainfall in the Lal Lal locality.
The present record does not establish that blade material, particles or contaminants entered a drainage line, waterway or Lal Lal Reservoir. The proximity and rainfall information are published as environmental context for the duration for which substantial material remained visible at the incident site.
29 May → 15 June → 27 August 2026
The environmental and clean-up questions were raised with the relevant authorities shortly after the incident and were revisited after the later 27 August footage became available. The sequence below is included so the later footage can be read against the earlier administrative record rather than in isolation.
29 May 2026
The Trustee provided the earlier blade-incident footage directly to EPA South West and Central Highlands Water for information, public-interest and record purposes.
The correspondence expressly raised debris containment and recovery, surrounding land, drainage lines and waterways, authority notification and environmental or public-health assessment. It made no allegation or finding about contamination or environmental harm.
15 June 2026
EPA advised the Beneficiary that it was “making enquiries into the broken wind farm blade” and stated:
“EPA’s role is limited to ensuring appropriate disposal and clean-up following the incident.”
That EPA response is preserved in the correspondence chain published with the 27 August Trustee enquiry.
27 August 2026 — 104 days later
After receiving the later footage, the Trustee returned the matter directly to EPA South West under ENQ231138 and asked EPA to clarify the status of its enquiries, inspection or verification, clean-up and disposal documentation, debris-dispersion assessment, drainage and receiving-environment assessment, outstanding remediation and whether EPA regarded the visible condition as consistent with the “appropriate disposal and clean-up” identified in its 15 June response.
PRI-00140148 — EPA describes incident material as “loose foam”
The Trustee has subsequently been provided with a redacted copy of an EPA Victoria response concerning a third-party pollution report lodged on 31 July 2026 in relation to the Y23 incident. The underlying third-party pollution report has not been provided to the Trustee. Accordingly, this record publishes and relies only upon EPA's response.
EPA stated that it had been in contact with Vestas, described in the response as the operator of the Lal Lal Wind Farm, and recorded that WorkSafe Victoria and Energy Safe Victoria had implemented an exclusion area around the turbine.
“Loose foam should be recovered as this exclusion zone is reduced and EPA will monitor the response.”
This statement is significant to the documentary record because EPA itself characterises at least some material associated with the failed blade as “loose foam”, states that it “should be recovered”, and records that EPA “will monitor the response.”
The response does not establish that all material visible at Y23 is foam, identify the chemical composition of the foam, establish contamination or environmental harm, or connect the Y23 material to the separate 2024 laboratory sample. Those matters are not established by this document.
Trustee places the laboratory material before EPA for independent consideration
On 4 September 2026, the Trustee wrote further to EPA South West concerning ENQ231138. The Trustee provided the redacted 2024 laboratory Certificate of Analysis and asked EPA to add the material to the existing record and independently determine whether it gave rise to any further enquiry, assessment or action within EPA's environmental regulatory role and its previously stated role concerning appropriate disposal and clean-up.
The Trustee expressly stated that it did not represent the laboratory material as establishing environmental contamination, environmental harm or regulatory non-compliance, and made no particular finding or conclusion from the laboratory results.
Documentary boundary: the laboratory Certificate concerns a separate 2024 sample identified by the laboratory as “TURBINE”. It is not an analysis of the Y23 debris. The significance of EPA's separate “loose foam” description is therefore that it forms part of EPA's own 2026 Y23 clean-up record; it does not establish a chemical link between the 2024 and 2026 material.
Further material provided; substantive clarification remains outstanding
The existing 4 September entry above records that the Trustee provided the 2024 laboratory Certificate of Analysis to EPA Victoria under ENQ231138 for independent consideration. That correspondence also asked EPA to confirm receipt, associate the pollution report with ENQ231138 and advise whether the laboratory material gave rise to any further enquiry, assessment or action. As at 13 September 2026, the Trustee has not received a substantive response to those requests.
Central Highlands Water: on 8 September 2026, CHW advised that EPA was the responsible regulatory authority, confirmed that EPA was aware of the incident and stated that any further action by CHW would be guided by EPA and its technical specialists. On 9 September, the Trustee sought limited further clarification because the earlier questions concerning CHW's own catchment, source-water and water-quality consideration had not been substantively answered. The Trustee also provided CHW with the same 2024 laboratory Certificate of Analysis, while expressly distinguishing that separate 2024 sample from the 2026 Y23 debris. As at 13 September 2026, no further substantive response has been received from CHW.
Documentary boundary: the absence of a later substantive response does not establish contamination, environmental harm, regulatory non-compliance or that CHW or EPA has reached any particular technical conclusion. It records the present administrative position: the further material has been supplied and the requested clarification remains outstanding.
Public-copy note: the published 27 August correspondence is a true-redacted copy. Only the Beneficiary's personal recipient email address appearing in the embedded 15 June EPA reply has been redacted; the substantive correspondence is otherwise preserved.

July 2024 enquiry and operator response
The correspondence is preserved in its original sequence and wording.
The operator’s 10 July 2024 response stated: The blade removal works was conducted to the project's environmental management processes.
Contemporaneous photographs
The captions describe only visible features. The images are not used to identify the composition of any material shown.
Pollution report, information request and operator response
EPA’s correspondence records an enquiry following a pollution report. The operator’s response records the controls and work methods it said were used.
EPA information request
EPA requested information after receiving a report concerning particles from blade cutting and potential impact to surface waters.
Operator explanation
The response described wet cutting, geofabric, minimising cuts, stopping work due to wind, an alternative method, sweeping after works and photographic records.
Safe Work Method Statement
The SWMS is contained within the EPA correspondence package and identifies dust as a hazard, with water suppression and other work-area controls described throughout the document.
The disclosed SWMS refers to measures including geofabric, bunding or encapsulation arrangements and water suppression. This page records those stated controls as documentary content; it does not independently verify their implementation at every stage of the activity.
Laboratory analysis — sample associated with blade-processing powder
Additional documentary material has subsequently been provided to the Trustee concerning a laboratory sample said, in the provenance accompanying its provision, to be associated with powder from the turbine-blade processing activity undertaken at the Lal Lal Wind Farm in 2024.
What the laboratory certificate itself records
The redacted Certificate of Analysis identifies the Client Sample ID as “TURBINE”, records receipt on 25 July 2024, and records the Certificate as reported on 19 August 2024. The analysis is described as a semi-volatile organic compound (SVOC) scan using GC-MS.
The public copy has identifying information redacted. The laboratory certificate itself does not describe the sample as “blade-processing powder”; that association comes from the provenance by which the material was subsequently provided to the Trustee.
Reported results and laboratory qualification
Table 1 records nine NIST tentative identifications of the top matches, including cyclopentasiloxane, decamethyl- and cyclohexasiloxane, dodecamethyl-.
The methodology states that library matches are tentative identifications and that definitive identification requires comparison with an authentic standard. The report provides retention-time, formula, area and match-score information, but does not report quantitative concentrations for the tentatively identified compounds.
Internal date discrepancy preserved: the Sample History page records an extraction date of 27 July 2020, while the Certificate records receipt of the sample on 25 July 2024 and reporting on 19 August 2024. Those dates are inconsistent on the face of the document. The Certificate does not explain the discrepancy, and this public record does not correct or infer the intended extraction date.
Relationship to the EPA record: this laboratory analysis is separate from the EPA material presently held concerning pollution report PRI-00080008. It has not been established that the analysis was provided to, or considered by, EPA in its original 2024 assessment of that blade-processing matter. The Certificate was subsequently provided to EPA Victoria by the Trustee on 4 September 2026 for independent environmental and regulatory consideration.
Its relevance to this page is confined to additional documentary information concerning the sample and the provenance by which it was provided to the Trustee. The report does not, by itself, establish pollution, environmental harm, regulatory non-compliance, the composition of all material produced during blade processing, or that any tentatively identified compound was present at a concentration exceeding an applicable regulatory threshold.
Public-copy note: identifying information has been redacted to protect the source. The analytical table, chromatogram, methodology and laboratory qualifications remain visible in the published copy.
FY24 Annual Statement
The statement records planned maintenance and unplanned blade and gearbox repairs. It is included because it forms part of the same period’s administrative record.
The statement does not expressly refer to blade processing, cutting, the Safe Work Method Statement, the environmental controls described to EPA or the later EPA dust enquiry. No conclusion is drawn on this page as to whether any further description was required.
What the available record shows
Established by the record
The Beneficiary raised the environmental-process and prior-notification questions in July 2024; EPA was copied; the operator gave a brief response; EPA later made a separate information request following a pollution report.
Recorded explanation
The operator later described the work methods and environmental controls it said had been applied and supplied supporting material to EPA.
Additional laboratory material
A redacted laboratory Certificate records an SVOC scan of a sample identified as “TURBINE” and nine tentative compound matches. Its association with blade-processing powder derives from the provenance accompanying its later provision to the Trustee, not from the Certificate wording itself.
Not established by these documents
The documents and laboratory analysis do not themselves establish pollution, EPA awareness or approval of the laboratory analysis, a regulatory finding of non-compliance, quantitative concentration exceedances, or that the tested sample is representative of all blade-processing material.
