Mykonos DEDDIE Yard: Inspection Orders Waste and Oil Cleanup

What the inspectors found

South Aegean regional environmental inspectors have ordered corrective action at a Hellenic Electricity Distribution Network Operator (DEDDIE) yard in the Agios Taxiarchis–Skylampela area of Mykonos. Their final report, dated 15 October 2026, follows an inspection on 26 March. It records two upheld violations: uncontrolled storage of non-hazardous discarded equipment and oil leaking onto the ground from six damaged transformers. The report describes visible spread down the slope and an odour. It does not publish laboratory measurements or establish the full extent of soil contamination.

The yard was also storing network equipment that DEDDIE said it intended to assess for reuse, repair or disposal. The regional authority did not accept the company’s explanation as sufficient proof that all the discarded material had been lawfully transferred to authorised recipients.

A third allegation was withdrawn

The preliminary inspection had also questioned whether this temporary storage activity required environmental authorisation. After considering DEDDIE’s explanation and the available inspection evidence, the final report accepted its position on that point. It did not retain the alleged authorisation violation. That distinction matters: the final findings concern the discarded materials and the transformer-oil leaks, not a finding that every activity at the yard lacked a permit.

DEDDIE told the inspectors that third parties had damaged the transformers, that it had filed a complaint against unknown persons and that it was planning soil-remediation work. The authority recorded those statements but held that third-party damage did not remove the observed oil-leak violation. This article does not independently establish who damaged the equipment.

What the order requires

For the non-hazardous waste, the report requires DEDDIE to provide collection and delivery records, or other evidence showing its destination, within one month of receiving the report. For the oil, it requires immediate measures to stop any continuing leaks and prevent further spread. It also calls for collection and lawful management of the hazardous waste, assessment of the affected soil, remediation and restoration, with supporting records and before-and-after photographic evidence. The timetable for that further work is ten months from receipt of the report. Its receipt date is not stated in the published copy, so these relative deadlines cannot be converted into verified calendar completion dates.

The report says compliance will be checked after the deadlines and warns of possible sanctions if the required steps are not documented or completed. It is an order for action, not evidence that cleanup has happened or that a fine has already been imposed.

Why residents should follow the next record

The regional service has referred the pollution-assessment and necessary soil-restoration question to the competent decentralised administration while continuing its own compliance process. The next meaningful public evidence would be DEDDIE’s documented waste transfers, a remediation plan and the authority’s later verification. Until then, the condition of the ground and completion of cleanup remain open questions.

The case concerns one utility storage yard. It is separate from the municipality’s island waste-site restoration funding announcement and should not be read as a finding about Mykonos waste management generally.
