What Is an ICPE?
An installation classée pour la protection de l'environnement (ICPE) is any factory, workshop, depot, construction site, or other installation operated or held by any person — public or private — that may present dangers or disadvantages for the neighbourhood, public health, safety, public hygiene, agriculture, nature, the environment, landscapes, or the rational use of energy (C. env., Art. L. 511-1). The classification is based on the nature and quantity of the products handled, stored, or processed on site.
| Regime | Code | Trigger | Key formality |
|---|---|---|---|
| Non-classified | NC | Below classification thresholds | Subject to the mayor's police powers only |
| Déclaration | D | No serious danger; below authorisation threshold | Declaration filed with the prefecture before commissioning |
| Déclaration avec contrôle | DC | As D, plus periodic inspection requirement | Declaration + periodic inspection by accredited body |
| Enregistrement | E | Intermediate regime (simplified authorisation) | Application to prefecture; local authorities consulted; possible public inquiry |
| Autorisation | A | Serious dangers or disadvantages for the environment | Full authorisation application including danger study, impact study, public inquiry |
| Autorisation avec servitudes | AS | Particularly serious dangers (Seveso high threshold) | As A, plus public utility easements restricting construction in the surrounding perimeter |
Who Is the Operator? Tenant, Not Landlord
The ICPE regime places all regulatory obligations on the exploitant — the operator of the installation. The concept of operator is specific to environmental law and entirely independent of the ownership or rental of the land. In a commercial lease context, the operator is almost always the tenant. Whether the tenant is the owner, a leaseholder, or a sub-lessee is irrelevant to the environmental authorities. The tenant who installs and operates an ICPE on leased premises must carry out all required formalities — declaration, registration, or authorisation — in their own name, and bears personal responsibility for compliance throughout the period of operation.
A tenant and sub-tenant who operated a warehouse for several years without verifying whether it complied with ICPE environmental regulations committed a fault, regardless of whether they knew of the non-compliance (Cass. 3e civ., 4 June 2009, n° 08-12.126). The obligation to comply with the police des installations classées rests on the operator. Ignorance of the classification status of an installation is not a defence.
When the Landlord May Also Be Liable
The landlord is not the operator and does not bear the primary ICPE obligations. However, a landlord who lets premises intrinsically intended to house ICPE — for example, a warehouse whose primary purpose is storage of classified products — without having first obtained the required declaration, registration, or authorisation, commits a contractual fault in the delivery obligation. Where the premises are intrinsically suited to ICPE activity, the landlord who delivers them without compliance has committed the primary fault and cannot then invoke the tenant's non-compliance against the tenant (Cass. 3e civ., 4 June 2009, n° 08-12.126).
When the Lease Ends: Site Rehabilitation Obligations
When an ICPE ceases activity, the operator — the tenant in most cases — bears a series of non-negotiable obligations under Articles R. 512-39-1 et seq., R. 512-46-25 et seq., and R. 512-66-1 et seq. of the Environmental Code.
Notification to the Prefecture
Cessation of activity must be notified to the prefect at least three months before the final shutdown of an authorisation or registration installation, and at least one month before for a declaration installation. A tenant who fails to notify the administration and fails to return the site to the required standard commits a fault and incurs personal liability until they can demonstrate compliance with all applicable measures (Cass. 3e civ., 21 September 2022, n° 21-17.431).
Site Securing and Rehabilitation
On cessation, the operator must at minimum: evacuate all dangerous products from the site; manage any waste present on site; prevent fire and explosion risks; monitor the effects of the installation on its surroundings; restrict access to the site; and return the site to a state that does not harm the interests protected by Article L. 511-1, allowing a future use comparable to the last period of operation.
Simply vacating the premises physically does not constitute legal restitution of the site. A tenant who returns the keys without having taken the required securing measures remains liable for an occupation indemnity until the date they can show compliance with the securing obligations (Cass. 3e civ., 19 May 2010, n° 09-15.255).
A tenant cannot avoid site rehabilitation by pointing to the landlord's stated intention to resume the same activity on the site at the end of the lease. The rehabilitation obligation is in the general interest of public health, public safety, and the environment — it is not a bilateral obligation that can be waived by the landlord's agreement. The operator remains bound regardless (Cass. 3e civ., 11 May 2022, n° 21-16.348). Rehabilitation costs may also be taken into account in the eviction indemnity calculation (CA Paris, 8 July 2020).
Transferring the Rehabilitation Obligation to a Third Party (Art. L. 512-21)
The ALUR Act (Law n° 2014-366 of 24 March 2014) and Decree n° 2015-1004 of 15 August 2015 introduced a procedure allowing the last operator of an ICPE to transfer their site rehabilitation obligation — in whole or in part — to an interested third party who plans to develop the site for a different use. The transfer requires the authorisation of the last operator, the mayor, the president of the EPCI, and the landowner (if not the operator). The ASAP Act (Law n° 2020-1525) further allows a second third party to substitute for the first. If the second party's intended use differs from the first's, full administrative formalities must be recommenced.
Site Security Certification Since 1 June 2022
Since 1 June 2022, all ICPE operators must engage a certified bureau specialising in polluted sites and soils after notifying the prefecture of their intention to cease activity. Authorisation and registration installations must also provide a rehabilitation report within six months of final shutdown. Three attestations (the "ATTES ASAP") are required at different stages, each conforming to the model in the ministerial order of 9 February 2022:
- Before signing: establish whether the activity to be carried on will constitute an ICPE and, if so, under which regime (D, DC, E, A, or AS). ICPE formalities must be carried out by the tenant-operator — not the landlord — in the tenant's own name. Ignorance of classification status is not a defence (Cass. 3e civ., 4 June 2009).
- Intrinsically ICPE premises: if the premises are intrinsically intended for ICPE use (warehouse, chemical storage), verify that the landlord has delivered premises for which the required regulatory status has already been obtained — a failure here is a landlord fault that reverses the liability allocation.
- Cessation notification: notify the prefecture 3 months before final shutdown for A/E installations; 1 month for D installations. Failure to notify and failure to rehabilitate the site both result in personal liability persisting until compliance is demonstrated (Cass. 3e civ., 21 Sept. 2022).
- Returning the keys does not end liability: physically vacating the premises does not constitute legal restitution. Occupation indemnity continues until all regulatory securing and rehabilitation measures are proven (Cass. 3e civ., 19 May 2010). Landlord's intention to resume the same activity does not waive the obligation (Cass. 3e civ., 11 May 2022).
- Third-party transfer (Art. L. 512-21): where the site has redevelopment potential, consider whether the rehabilitation obligation can be transferred to a third-party developer. Since June 2022, engage a certified bureau and produce the three ATTES attestations (SECUR / MEMOIRE / TRAVAUX) at each stage of cessation and rehabilitation.
The intersection of environmental law and commercial lease law generates complex obligations that can result in significant financial exposure at the end of a lease.
