Planning a plant closure: legal basis, scheduling, dismantling phases and documentation. A practical guide for operators and project managers.
A plant closure in an industrial context is subject to a dense web of federal and Land legislation. Operators are obliged to notify the competent immission control authority of the dismantling, or to obtain its approval — depending on the type of plant and the underlying permit. For plants subject to the Federal Immission Control Act (BImSchG), a formal notification of decommissioning under § 15 BImSchG is required at least one month before operations cease.
Practical note: early consultation with the authorities
Contact the competent permitting authority at least six months before the planned decommissioning. A preliminary meeting allows open questions about aftercare obligations, the obligation to dismantle and any investigations into contaminated land to be clarified before formal deadlines start to run.
The schedule for a plant closure does not begin with the first demolition excavator, but with the strategic decision to close the site. For medium-sized industrial sites, 12 to 24 months typically elapse between the decision and a development-ready site — and considerably longer for contaminated sites. A realistic schedule takes account of permitting procedures, hazardous-substance investigations, tendering and the operational dismantling phase.
The critical path: permits
The most common cause of delay is missing or incomplete permits. Make sure that the demolition permit, the hazardous-substance remediation concept and the disposal records are prepared in parallel — not sequentially.
A plant closure affects numerous stakeholders, all of whom have to be involved. Structured stakeholder management prevents blockages and creates the conditions for a smooth process. Involving all parties at an early stage — from the workforce and the authorities through to neighbouring municipalities — is decisive for the success of the project.
External communication
Actively inform the neighbourhood and the municipality about the planned dismantling. A named contact for residents' questions and a transparent schedule reduce complaints and conflict considerably.
Operational dismantling is divided into clearly defined phases that build on one another. Each phase has its own requirements in terms of personnel, equipment, permits and documentation. The sequence is prescribed both technically and legally: hazardous-substance remediation before demolition, soft strip-out before building demolition, soil investigation before handover.
Selective dismantling vs. conventional demolition
Selective dismantling separates materials as the demolition proceeds and achieves recovery rates of over 90 %. It is admittedly more demanding than conventional demolition with subsequent sorting, but it results in lower disposal costs and meets the requirements of the KrWG (Closed Substance Cycle Waste Management Act) regarding the waste hierarchy.
The cost of a plant closure is made up of numerous individual items and varies considerably depending on the size of the site, the degree of contamination and regional disposal prices. A robust cost estimate requires a qualified site survey — lump-sum quotations produced without knowledge of the site are generally unreliable.
Material revenues as a cost offset
Depending on market conditions, steel scrap, non-ferrous metals and recoverable building materials can offset a considerable share of the dismantling costs. Have the quantities determined before the contract is awarded — the revenues should be taken into account in the overall calculation.
Complete documentation is not optional in industrial dismantling; it is mandatory. It protects the client legally, provides evidence of proper disposal and forms the basis for a subsequent declaration of exemption from contaminated land liability. Without complete documentation there is a risk of liability extending well beyond the end of the project.
Digital documentation
Opt for digital project documentation with a uniform folder structure, version control and access management. Authorities increasingly expect digital records, and structured documentation makes subsequent information obligations considerably easier to meet.
