contaminated site

noun · Altlast

An Altlast is a disused waste disposal site or a former industrial site from which harmful soil changes or other dangers proceed, and German law spreads responsibility for it widely: the polluter, his universal successor, the present owner and the person in actual control can each be required to remediate, so a purchaser acquires the liability with the land.

Which translation, when

Zustands- und Handlungsstörerwho must remediate: responsibility does not stop at the person who caused the contamination but reaches the current owner and the holder of actual control over the land, and it also reaches the previous owner in defined cases, so a buyer who knew nothing of the history can be the addressee of the order and must then seek recourse from the polluter.

Auswahl und Ausgleichhow the burden is allocated: the authority selects the addressee by effectiveness rather than by fault, which regularly means the solvent owner rather than the vanished operator, and the statute then provides for compensation among those responsible, so the internal allocation is settled afterwards and not in the order itself.

Vertragspraxiswhat purchase agreements do about it: because the liability follows the land, German transactions work with site investigations, environmental warranties, indemnities and sometimes escrowed retentions, and a translated share or asset purchase agreement that omits them leaves a risk the statutory rules will not allocate as the parties expect.

Why

Contaminated site is the Altlast, and the German concept covers two situations named separately in the statute: disused waste disposal sites and former industrial or commercial sites, in each case where harmful soil changes or other dangers for individuals or the general public proceed from them. What makes the term matter in commercial practice is not the definition but the breadth of responsibility. German soil protection law does not confine the duty to remediate to the person who caused the contamination. It reaches his universal successor, the current owner of the land and the person exercising actual control over it, and in defined circumstances a previous owner as well. The authority chooses among them by what will remove the danger most effectively, not by who is to blame, which in practice means the solvent present owner rather than an operator who disappeared decades ago. The statute then provides for compensation among those responsible, so the internal allocation happens after the remediation rather than in the order that requires it, and a purchaser who bought without investigating carries the cost until he can recover it. This is why German property and corporate transactions treat contamination as a distinct workstream, with technical site investigations, environmental representations, indemnities and sometimes retained funds, and why a translated purchase agreement that carries none of them into the German context leaves the buyer exposed. The duties an operator owes for his own site after closing it down belong to the operator obligations entry.

Typical mistakes

Responsibility for remediation reaches the present owner and the person in actual control, so a purchaser can be the addressee although he caused nothing.
The authority selects the addressee by effectiveness rather than by fault, so the polluter being identifiable does not protect the owner.
Compensation among those responsible is settled after the remediation, so the order itself does not allocate the burden internally.

What matters

Advising on a German site acquisition: the due diligence should cover the industrial history, price the remediation risk, and secure indemnities, since the statutory responsibility follows the land rather than the fault.

Authority

§ 5 BImSchG

What the machine misses

The engine renders contaminated site as kontaminierter Standort or Umweltschaden, the second a term of a different statute, and the German concept is the Altlast, a disused disposal or industrial site from which harmful soil changes proceed; the loose rendering also hides that responsibility follows the land, so the present owner can be ordered to remediate what someone else caused.
