RegulationA compliance recommendation for Auguste Victoria — and for the German and Polish mines either side of it
The regulation turned Europe’s closed mines from forgotten liabilities into dated obligations. This page reads that text as an operating plan: what is owed, by whom, by when — and what a site would actually have to build to meet it.
Art. 25(6) — source-level estimates for the last available calendar year, then annually by 31 May.
Art. 26(1) — member-state plans with key implementation milestones, closed and abandoned mines alike.
Art. 26(2) — both, not just venting. The exceptions are demonstrated technical infeasibility and risk to safety.
Art. 33 — the regulation requires penalties for infringements, and caps administrative fines at this share of annual turnover for the infringements Art. 33(2) enumerates.
The physics the deadlines are written against, in the regulation’s own words: “It is estimated that even 10 years after mining has ceased, methane from non-flooded coal mines continues to be emitted at levels attaining approximately 40% of those recorded at the time of closure.” — recital 54. Reported
The compliance clock · Arts. 24–26
Closed mines are already inside the reporting window.
Measurement has been required since May 2026. The first reports are days away as of 2026-08-04, the mitigation plans follow six months later, and the 2030 prohibition removes the last cheap answer — flaring — at the same moment it removes venting.

Inventories dueArt. 25(1)
Member states publish an inventory of all closed and abandoned underground coal mines where operations ceased after 3 August 1954.
- 2026-05-05passed
Measurement beginsArt. 25(2)
Methane measurement required on all inventoried elements found to emit above 0.5 t CH₄/yr.
- 2026-08-05passed
First emissions reportsArt. 25(6)
First yearly reports of source-level methane emissions — estimates, covering the last available calendar year; annually by 31 May thereafter.

Mitigation plansArt. 26(1)
Member state mitigation plans covering closed and abandoned mines alike, with key implementation milestones.

Venting & flaring prohibitedArt. 26(2)
Venting and flaring prohibited outright for in-scope equipment; the only exceptions are demonstrated technical infeasibility or a risk to safety.
Closed mines — the operator owes it
Where an operator or licensee still exists, the measuring and reporting fall to them. At Auguste Victoria that is RAG, which already carries the Ruhr’s perpetual mine-water obligations. Reported
Abandoned mines — the State owes it
Where no responsible party remains, Art. 25(7) puts the same duties on the member state itself. For the abandoned Silesian and Ruhr workings this makes mitigation a public-budget question. Reported
The two ways out
Both exits are earned with measurement, and only with measurement — which is why the instrumentation step below comes before any abatement decision. Reported
- Art. 25(3)A source measured below 1 tonne CH₄ per year for six consecutive years at a flooded mine, or twelve at a non-flooded one.
Monitoring ends for that source — per source, not per site, so the site record is only as good as its worst shaft.
- Art. 25(4)A mine fully flooded for at least ten years before the request is made, where the responsible party demonstrates both hydrogeological stabilisation and the absence of material methane emissions. The competent authority may then grant it; it is not automatic.
Exemption from the measurement obligations Art. 25(4) names — narrower than an exit from the regulation, and reversible if material emissions are later evidenced.

The active-mine track · Arts. 20–23, 29
Poland’s clock runs first.
The closed-mine articles are only half the instrument. For mines still producing, a second track bans drainage venting outright, then caps ventilation-shaft emissions against coal output — a limit that decides which Polish mines have a future before any closure obligation is ever reached.
- 2025-01-01passed
Drainage venting bannedArt. 22(1)
Venting methane to the atmosphere from drainage systems prohibited, and flaring permitted only in devices achieving at least 99% destruction and removal efficiency by design — emergency, malfunction and defined maintenance aside.
- 2027-01-01ahead
Ventilation shafts cappedArt. 22(2)
Venting through ventilation shafts prohibited where emissions exceed 5 tonnes CH₄ per kilotonne of coal mined, at mines other than coking coal mines.
- 2027-08-05ahead
Coking-mine act dueArt. 22(3)
Commission delegated act due, setting the venting restrictions that will apply to coking coal mines — until it lands, coking mines sit outside the ventilation threshold.
- 2028-08-05ahead
Methane intensity reportedArt. 29(1)
Methane-intensity reporting begins for coal placed on the Union market, importers and EU producers alike.
- 2030-08-05ahead
Intensity ceilings bindArt. 29(2)
Maximum methane-intensity values apply to new supply contracts; the text sets the date as by 5 August 2030, so the operative day may fall earlier.
- 2031-01-01ahead
Threshold tightensArt. 22(2)
The ventilation-shaft venting threshold falls from 5 to 3 tonnes CH₄ per kilotonne of coal mined.
Every date above is regulation text rather than forecast. Reported The 2030 intensity date is written as an outer bound — “by 5 August 2030” — so the operative day may fall earlier.
The Auguste Victoria plan · five steps, in order
What compliance would actually look like on one site.
The recommendation, sequenced the way the site would have to run it: measure first, use the gas while it is still worth using, choreograph everything against the rising water, then engineer the lean tail nobody has solved yet.
Instrument every point source
Measurement on inventoried emitting elements has been legally required since 5 May 2026 under Art. 25(2) Reported — continuous sensors on shaft caps and protector pipes, plus quarterly site-level surveys to catch diffuse leakage through backfill that point sensors never see.
Auguste Victoria’s flooded status is publicly unresolved Unknown and the mine is modelled at ≈28 MCM ≈ 19 kt CH₄ per year Modelled. Neither number is a measurement, and the measurement record is what determines which of the two exit ramps above is even reachable.
Extract and use it while it is still engine-grade
Rising mine water acts as a piston, displacing stored gas upward during rebound Reported — UNECE’s abandoned-mine methane guidance, ECE Energy Series No. 64. The consequence is counter-intuitive: the coming years are the emission peak window, not the tail end of one.
So the capture case is strongest now. Abandoned-mine methane CHP on the pattern of the existing Ruhr fleet takes the engine-grade gas; a flare at ≥99% destruction and removal efficiency Reported is a backstop for outages, not a plan — and after 1 January 2030 it is not an option at all.
Choreograph against the water
RAG’s staged mine-water rise takes the workings to about −600 m Reported, and a mine fully flooded for ten years with demonstrated hydrogeological stabilisation can be exempted from the measurement obligations under Art. 25(4). The gas programme and the water programme are therefore one schedule, not two.
Flooding is not a free win: it trades methane for induced seismicity and water-quality risk, as the FloodRisk research in the eastern Ruhr documents Reported. A plan that sells flooding as pure upside is not describing the same site.
Oxidise the lean tail
Below engine-grade concentrations the gas still has to go somewhere. Lean-gas burners take the middle band; engineered methanotrophic oxidation — biocovers and biofilters — takes the diffuse, low-flow residual that follows. Regenerative thermal oxidisers need sustained flow a sealed shaft does not provide Estimated.
This tail stage is, in the sources reviewed as of 2026-08-04, the EU-wide gap the February 2027 mitigation plans will expose Estimated: the deadlines assume a treatment route for concentrations that most installed equipment cannot handle.
Pair it with the sanctioned re-use menu
The regulation names the alternatives itself — recital 62 and Annex VIII Part 3, point 2, list mine-water geothermal, heat storage, and hydropower in non-flooded workings Reported. These are the uses that make a perpetual obligation carry a return instead of only a cost.
With a catch worth designing around: under Art. 26(3) the holder of an alternative-use permit inherits the monitoring and mitigation obligations Reported. Re-use is not an exit from the methane duty — it is a transfer of it.
Germany and Poland · the two that matter
The same text, two very different problems.
Germany has a handful of deep, gassy closed mines and a capture fleet already built. Poland has the volume, the operating mines, and the earlier deadlines. One country is scheduling; the other is deciding which mines survive.
Germany
≈55 MCM CH₄/yr · abandoned mines Modelled
Few mines, deep and gassy, and an abandoned-mine methane fleet that already burns most of what it catches. The work here is preservation and scheduling, not invention.
Reported only three abandoned underground mines but very deep, gassy coal; reportedly utilises ≈99% of its captured abandoned-mine methane — the sources do not resolve whether the denominator is captured or total gas.
What the record shows
- Modelled Auguste Victoria alone is modelled at ≈28 MCM CH₄ per year — around half of the German abandoned-mine total in the study inventory.
- Reported These are closed-mine obligations, not abandoned-mine ones: the operator or licensee measures and reports, and the State steps in where no responsible party remains (Art. 25(7)).
The playbook
- Run the Auguste Victoria sequence at each site, scaled to its shaft count and rebound stage.
- Keep the existing AMM-CHP fleet economic rather than letting units retire as concentrations decline.
- Publish the mine-water rise schedule per mine, so the flooded-status exemption under Art. 25(4) can actually be evidenced when the ten years are up.
- Treat the lean tail as a design problem now — the fleet was built for engine-grade gas and will outlive the concentrations that feed it.
Poland
≈110 MCM CH₄/yr · abandoned mines Modelled
The largest single block of EU coal methane, and the only one where the operating-mine track decides the outcome before the closed-mine deadlines are reached.
Modelled ≈40% of EU abandoned-mine methane; most abandoned underground hard-coal mines in the EU.
What the record shows
- Reported Across the whole coal sector, operating mines included, Poland accounts for roughly 70% of EU coal-mine methane in the sources reviewed — a wider denominator than the abandoned-mine share above.
- Reported JSW's five coking mines emit ≈197 kt CH₄ per year and sit outside the ventilation-shaft threshold until the coking-mine delegated act, due 5 August 2027.
- Reported Ventilation-air methane regenerative thermal oxidisers reach ≈98% destruction at ≈€250 per tonne CH₄ over a ten-year life.
- Reported PGG's thermal-coal mines meet the 5 t CH₄/kt threshold on 1 January 2027 — abate, or close.
The playbook
- Commit VAM oxidiser capacity at the thermal mines now; the 2027 threshold is not survivable on drainage improvements alone.
- Treat the coking exemption as a deadline, not a reprieve — the delegated act arrives before any oxidiser ordered after it could be commissioned.
- Price closure against abatement explicitly, mine by mine, so that closures happen as decisions rather than as compliance failures.
- For the abandoned Silesian mines the State carries the obligation directly under Art. 25(7), which makes the mitigation plan a public-budget question, not an operator's.
The two country figures above answer different questions and should not be added together: the headline number counts modelled abandoned-mine methane in the study inventory, while Poland’s ≈70% share Reported covers the whole coal sector, operating mines included.
