EIA Regulations meaning

Published by a LexisNexis Energy expert
What does EIA Regulations mean?
In practice, EIA Regulations refers to the suite of statutory instruments governing environmental impact assessment in planning and consenting. In England, the key instruments are the Town and Country Planning (Environmental Impact Assessment) Regulations 2017 and the infrastructure Planning (Environmental Impact Assessment) Regulations 2017 (for Planning Act 2008 nationally significant infrastructure projects (NSIPs)), both in force since 16 May 2017 and amended. Wales, Scotland and Northern Ireland have parallel 2017 planning EIA regimes. Sector‑specific EIA rules also apply (for example marine works, highways and electricity). Decommissioning of nuclear reactors is governed by the Nuclear Reactors (Environmental Impact Assessment for Decommissioning) Regulations 1999, as amended (including in 2018). In Ireland, EIA is provided under the Planning and Development Act 2000 and Regulations 2001, as amended (including the 2018 Regulations). These instruments implement the EIA Directive (2011/92/EU, as amended) in domestic law, requiring screening, scoping, an environmental statement/EIA report, public participation, and a reasoned conclusion before permission or a development consent order is granted. The term is descriptive rather than a single defined expression; within the regulations, defined terms such as “EIA development” and “Schedule 1/Schedule 2 development” are used. Usage is broadly consistent across the UK and Ireland.

High Court quashes Norfolk Vanguard development consent for failure to assess cumulative impacts with Norfolk Boreas under EIA Regulations 2009: unlawful deferral and inadequate reasons (England and Wales)

Pearce v Secretary of State for Business, Energy and Industrial Strategy [2021] EWHC 326 (Admin) What are the practical implications of this case? While the facts are specific to this matter, multiple offshore schemes along England’s east coast are moving through consent, and each must robustly account for cumulative effects. The case also underlines mounting pushback from local communities against sizeable onshore infrastructure in the area, coinciding with BEIS’s programme reviewing offshore transmission and different approaches to linking offshore wind schemes and landing renewable power. The court further made clear that, even where a proposal aligns with government policy and helps deliver low‑carbon, renewable generation consistent with legal duties towards ‘net zero’ and tackling climate change, that alignment does not displace the requirement for any application to evaluate every impact properly and in accordance with the law. All such proposals therefore need to demonstrate, through the application process, that cumulative and project‑specific effects have been considered with sufficient rigour, rather than assuming policy support or climate objectives will...

Waste planning law and policy in England: national framework, plan-making, development management, EIA, applications, conditions and obligations; interface with pollution control; with Welsh planning guidance

National policy 25-Year Environment Plan —the 25-Year Environment Plan outlines the government’s commitments to enhance the environment within a generation. The Environmental Improvement Plan 2023 (EIP 2023) for England was the first statutory update to the 25-Year Environment Plan under the Environment Act 2021 (EA 2021). On 1 December 2025, it was replaced by the Environmental Improvement Plan 2025 (EIP 2025), now the current environmental improvement plan for EA 2021 purposes. EIP 2025 renews the long-term framework for achieving environmental outcomes, revises the interim targets in EIP 2023 and adds two new interim targets. EIP 2025 is pertinent to waste planning as part of the broader policy to improve resource efficiency and drive the move to a more circular economy, complementing the Resources and Waste Strategy and the Waste Management Plan for England (see below). Resources and Waste Strategy The Resources and Waste Strategy sets out how the government intends to conserve material resources by cutting waste, promoting resource efficiency and moving towards a circular economy in...

EIA in Town and Country Planning: Screening, Scoping, Project Definition, Multi-stage Consents and Key Case Law (England and Wales)

Key legislation Environmental impact assessment (EIA) safeguards the environment by obliging the planning decision‑maker, including a local planning authority (LPA), when determining whether to grant planning permission for a project likely to have significant environmental effects, to take those likely significant effects into account in the decision‑making process within town and country planning matters as part of that decision‑making process. In the context of town and country planning, EIA is regulated by: the Town and Country Planning (Environmental Impact Assessment) Regulations 2017 (English EIA Regulations), SI 2017/571 in England; and the Town and Country Planning (Environmental Impact Assessment) (Wales) Regulations 2017 (Welsh EIA Regulations), SI 2017/567 in Wales together, the ‘EIA Regulations’. The EIA Regulations implement into English and Welsh law the changes introduced by Archived Directive 2014/52/EU to Archived Directive 2011/92/EU on assessing the effects of certain public and private projects on the environment (as they had effect immediately before IP completion day—11 pm on 31 December 2020), insofar as they...

Post-Brexit planning legislation tracker: key SIs and Acts on EIA/SEA, habitats, hazardous substances and border facilities in England and Wales

This Tracker helps planning practitioners keep up to date with Brexit legislation that affects their areas of practice. A series of Brexit SIs have been made, exercising powers under the European Communities Act 1972 and the European Union (Withdrawal) Act 2018 (EU(W)A 2018), to fix failures of assimilated law (previously referred to as retained EU law) to function effectively after exit, and other deficiencies arising from the UK’s withdrawal from the EU. Items of particular relevance to planning lawyers are included in the table below. The table also outlines bills/Acts of Parliament arising from Brexit which may interest planning practitioners.
