The European Regulatory Response to the Volcanic Ash Crisis between Fragmentation and Integration

More than twenty years after the EU eliminated its internal land borders, the Union still lacks an integrated airspace. This seems to be the most immediate regulatory lesson of the recent volcanic ash crisis. Yet more research is needed before establishing its net effects.

In this brief report, I will provide a first-hand analysis of the regulatory answer developed across Europe in the aftermath of the eruption of the Icelandic volcano Eyjafjallajökull. While reconstructing the unfolding of the events and the procedures followed by the regulators, I will attempt to address some of the questions that I have repeatedly asked myself when stranded in Washington DC between 16 and 25 April 2010. Who did the assessment of the hazard posed by volcanic ash to jetliners? Who was competent to take risk management decisions, such as the controversial flight bans? Is it true that the safe level of volcanic ash was zero? How to explain the shift to a new safety threshold (of 2,000 mg/m3) only five days afterthe event? Did regulators overact? To what extent did they manage the perceived risk rather than the actual one? At a time when the impact of the volcanic ash cloud crisis is being closely scrutinised by both public authorities and the affected industries, it seems particularly timely to establish what happened during the worst aviation crisis in European history. This report was written one week after the event and relied on a limited number of sources
available by 30 April 2010.

Alice’s Adventures in Volcano Land: The Use and Abuse of Expert Knowledge in Safety Regulation
© Lexxion Verlagsgesellschaft mbH (6/2010)
As a volcano refugee in Frankfurt, it was rather interesting to see a slow motion regulatory science disaster taking place. On April 14 2010 the Icelandic volcano Eyjafjallajökull erupted sending millions of tons of ash into the upper atmosphere. The ash cloud, blown by the prevailing winds, moved down over northern Europe. European air traffic authorities, following well established and widely published safety protocols, began shutting down the air transport system due to the well known hazard of volcano ash.

Entwicklung der Emissionsgrenzwerte in der Abfall- und Energiewirtschaft – Europa und Deutschland –

In Europa kann – bezogen auf verbindliche Emissionsgrenzwerte – ein grundsätzlicher Unterschied der Regelungsphilosophien festgestellt werden. Ein zahlenmäßig sehr dominierendes Lager möchte so wenig wie möglich verbindliche Grenzwerte und ein hohes Maß an Flexibilität seitens der Mitgliedsstaaten. Dieses Lager wird angeführt durch Großbritannien.

Sichere, zuverlässige Entschwefelung hoher und sehr hoher H2S-Beladungen durch UgnCleanTubes®
© Agrar- und Umweltwissenschaftliche Fakultät Universität Rostock (6/2016)
Zylinderförmige UgnCleanPellets® S 3.5 für die zuverlässige und sehr kostengünstige Entschwefelung von Biogas sind seit einigen Jahren markteingeführt und (zumindest in Fachkreisen) hinlänglich bekannt. Die warme und feuchte Energie des Rohbiogases aus dem Fermenter wird dabei gezielt genutzt, statt vernichtet und der Störstoff Schwefelwasserstoff wird in den Wertstoff Schwefel – mit seiner düngenden Wirkung ‒ überführt.
