Decommissioning meaning

Published by a LexisNexis Energy expert
What does Decommissioning mean?
Decommissioning describes the end‑of‑life phase of an energy or industrial installation: the managed cessation of operations, making safe, plugging and abandonment (for wells), dismantling and removal of plant, equipment and materials, waste management, and environmental remediation and restoration of the site. It is a descriptive expression used across multiple regimes, but in key sectors it is governed by statute, licences and consents. In the UK, offshore oil and gas decommissioning is regulated under the Petroleum Act 1998 (requiring an approved decommissioning programme and imposing continuing liabilities). Offshore renewables and pipelines are covered by the Energy Act 2004. Nuclear decommissioning is addressed by the Nuclear Installations Act 1965, the Energy Act 2004 (NDA) and the Energy Act 2008 (funded decommissioning programmes). In Ireland, petroleum and offshore infrastructure are governed by the Petroleum and Other Minerals Development Acts and maritime planning legislation, with environmental licensing (including EPA closure and aftercare obligations) for relevant onshore sites. Key legal features include: regulator approval of a decommissioning programme; allocation of liability among operators, owners and former participants; financial security (trusts, bonds or guarantees); compliance with environmental, health and safety and waste law; and post‑closure monitoring. Usage is broadly consistent across England and Wales, Scotland, Northern Ireland and...

Planning and Regulatory Framework for Radioactive Waste in England and Wales: Geological Disposal (NSIPs), Non-geological Routes (TCPA), Policy, Consents, Consultation and Case Law

Scope of this Practice Note This Practice Note sets out the main types of radioactive waste and examines disposal against the EU-defined waste hierarchy. It places contemporary management of radioactive waste within the historical development of the nuclear industry from a planning standpoint. Principal policy documents are reviewed to chart the evolution of government thinking over time. Geological disposal of Higher Activity Waste (HAW) under the Planning Act 2008 (PA 2008) is compared with alternative disposal routes under the Town and Country Planning Act 1990 (TCPA 1990) and the Planning (Wales) Act 2015. Consultation duties, application processes and required consents are identified for both regimes. Notable planning appeals and judicial review cases are highlighted before looking at international approaches to radioactive waste. What is radioactive waste? In the UK, radioactive waste arises—and will arise—from past, current and future programmes for electricity generation from nuclear fission, the reprocessing of nuclear fuel, the development of nuclear weapons, the nuclear submarine fleet and wastes from radioactive materials used for civil...

Health and safety in nuclear decommissioning: legal framework, regulators' interfaces, emergency planning and post-Brexit/assimilated law developments

What is the impact of Brexit on the UK nuclear sector? As of 31 January 2020 (exit day), the UK ceased to be an EU Member State. From that date, a transition/implementation phase applied, during which the EU continued, for many purposes, to treat the UK as if it remained a Member State. Leaving the EU also entailed withdrawal from the Euratom Community. The transition ended at 11 pm (GMT) on 31 December 2020—known in UK law as ‘IP completion day’. At that point, key transitional measures expired and notable shifts started to apply across the UK’s legal framework. The UK’s exit from the EU likewise meant departure from Euratom. Any changes pertinent to this content are outlined below. Following IP completion day, the European Union (Withdrawal) Act 2018 (EU(W)A 2018) introduced a new category of domestic law—‘retained EU law’ (REUL)—comprising EU-derived rights and legislation preserved in the UK after Brexit. On 29 June 2023, the Retained EU Law (Revocation and Reform) Act 2023 (REUL(RR)A 2023) received Royal Assent...

UK offshore upstream oil and gas insolvency and restructuring: a legal practitioner's guide to OGA licensing and consents, JOAs, decommissioning liabilities, cross-border issues, and officeholder options

Introduction to common participants in the market The oil and gas sector is a major contributor to the UK economy: It supports around 152,000 jobs, both directly and indirectly It accounted for 0.8% of GDP in Q2 2015, down from a peak of 2.5% in Q2 2008 Government revenues from production in 2016/2017 were £1.2bn The UK is Europe’s second largest oil producer and the third largest gas producer Historically, the industry has been buoyant, with limited involvement from insolvency practitioners. In 2010, there were only four insolvencies in the sector. However, when oil prices fell to a record low in 2015, the number of insolvencies increased to 28 that year. Due to its maturity, the UK continental shelf is among the more expensive regions globally for oil production: before the 2015/2016 downturn, producing a barrel in the UK cost about US$40, compared with under US$5 in Kuwait. These costs have somewhat reduced since the 2015/2016 downturn...

UK Decommissioning Relief Deed (DRD): Tax Relief Certainty, Potential Government Payments and Prescribed Non‑Amendable Form for Oil and Gas Operators

The DRD is designed to give clarity over the tax relief a Qualifying Company will obtain at the point of decommissioning and, in certain circumstances, can lead to a payment by the UK Government to the Qualifying Company. For further detail on DRDs, refer to Practice Note: Decommissioning:—overview of the decommissioning relief deed. The DRD follows a mandated template and is not open to amendment...
