In the Nineties, the deliberate closure of Alsace’s potash mines gave rise to the thought of storing hazardous waste in galleries dug into the rock salt at a depth of round 550m beneath the city of Wittelsheim, close to Mulhouse. ‘Again then, there was a have to repurpose mining websites,’ says Frédéric Bierry, present President of the European Collectivity of Alsace, an administrative area created from a merger of the Haut-Rhin and Bas-Rhin departments.
In 1997 the prefect of Haut-Rhin authorised the StocaMine firm, a now defunct subsidiary of the general public firm Mines de Potasse d’Alsace (MDPA), to handle the ‘reversible underground storage of commercial waste’ that was non-radioactive, strong, inert and non-flammable. The authorisation permitted the burial of 320,000 tonnes within the Joseph Else mine. Between 1999 and 2002, 44,000 tonnes of waste have been progressively saved in blocks of purpose-built galleries. ‘The federal government gave an enterprise that storage could be strictly managed and reversible, pending the event of future applied sciences that may allow the remedy of those supplies,’ says Jean Rottner, president of the Grand Est area, of which Alsace is part.
However then, between 10 September and 21 November 2002, a fireplace ravaged block 15, which contained 1,775 tonnes of waste, poisoning 76 workers. The hearth led to the burial of waste being suspended after which deserted the next 12 months. A judicial inquiry discovered that probably self-igniting supplies had been buried on the energy of incomplete identification sheets, constituting ‘critical and repeated failings’ that ‘replicate[ed] the will to simply accept at any value’ substances of natural origin and fertiliser residues from the Solupack firm. The positioning director had breached the protection necessities, ignoring warnings from employees, his deputy and the labour inspectorate. On 15 April 2009 he was convicted on attraction for ‘endangering others’, as was StocaMine as a authorized entity.
Underneath the Rhine water desk, one of many largest in Europe, lies a time bomb that worries native residents in Alsace and their Swiss and German neighbours. François Zind, a lawyer for the Alsace Nature organisation, says, ‘The official estimate is that there are 26 tonnes of mercury, 1,747 tonnes of arsenic, 33 of cadmium, 32 of chromium, 250 of lead and 100 of antimony [stored in the mine]; 50 pollution have been recognized, most of them soluble in water and brine.’
The state has not saved its promise that the storage of hazardous waste ought to be reversible. Even when recognized as harmful, the waste has remained deeply buried, although pressing motion is important to retrieve it. Galleries dug in potash have a pure tendency to contract, which means they are going to change into inaccessible sooner or later between 2027 and 2029, in line with reviews, and collapse a number of years later. Then, in line with France’s Geological Survey, the Bureau de Recherches Géologiques et Minières (BRGM), progressive flooding may dissolve soluble supplies and carry contaminated brine into the water desk 500m above (1).
The federal government, which was strongly criticised in 2014 by the Court docket of Auditors for its failure to behave, produced a number of professional reviews selling its favoured resolution: on-site containment in a concrete enclosure. Following an modification proposed by Michel Sordi, the member of the Nationwide Meeting for Haut-Rhin, the environmental code had been modified in 2004, two years after the fireplace. Thereafter hazardous supplies could possibly be saved underground with out restrict ‘if the enter of waste had ceased multiple 12 months earlier’.
Underneath strain from the general public and politicians on all sides, the federal government agreed to extract essentially the most poisonous waste; 95% of the mercury was eliminated between 2015 and 2017. Of the remaining 42,000 tonnes of waste, 25% continues to be soluble, ‘with a danger to the ingesting water provide — the one criterion thought of by the state — talked about in quite a few reviews, but in addition attainable impacts on the whole meals chain linked to floor water, as nearly all of this waste is endocrine disruptors,’ Zind says.
In keeping with BRGM, the price of this mission — which comes on prime of an annual value of €5m since 2002 — varies in line with what interventions precede containment: €87m if there isn’t any additional extraction; €246-307m with the removing of soluble waste solely; and €379-440m for the removing of all waste. The federal government claims these final two eventualities are too costly and too harmful, and nonetheless backs the everlasting containment of the remaining waste. Bierry opposes this: ‘In Decrease Saxony, an identical state of affairs finally led the German authorities to take away every little thing urgently, which value €2bn. We now have no long-term assure if the water degree rises, and we’re speaking right here about containing subsoil on a seismic fault line. This isn’t performing responsibly in direction of future generations.’
The state is engaged in a race with the regulation. Alsace Nature and the native authorities went to the executive courtroom of attraction in Nancy, which annulled the prefectoral decree on 15 October 2021, primarily over the absence of economic ensures, thereby blocking the containment work that was on account of begin that day. Nevertheless, an modification quietly handed by the Nationwide Meeting a month later permitted the state to offer monetary ensures to MDPA and once more authorised containment for an ‘limitless interval’. On 28 December the Constitutional Council censured this measure, which it thought of a ‘non-financial legislative provision’.
On 28 January 2022 the prefect of Haut-Rhin issued an extra order authorising work to renew and opening the best way for a brand new authorisation software after a public inquiry. Rottner is disillusioned by the federal government’s intransigence: ‘The native authorities have been attempting to speak to them for years and we’ve even discovered industrialists with options… We naturally find yourself questioning why there’s such an absence of transparency and session.’
In January 2021 a go to from the minister for ecological transition, Barbara Pompili, raised hopes that discussions may start. ‘We alerted her to the clear future danger. A month later, the federal government merely confirmed its need to include the location as is. We face incomprehensible stubbornness,’ says Stéphane Giraud, director of Alsace Nature. Along with the numerous French and European specialists calling for the waste to be eliminated, some miners are actually saying there’s nonetheless time to intervene. As the federal government initially dedicated to reversible storage of the waste, folks’s religion in its phrase can also be on the road.
