When Is An Environmental Impact Assessment Needed?

 

In the construction industry, understanding environmental regulations is critical to ensuring that projects comply with the law while minimising potential harm to the environment. One of the most important tools in this regard is the Environmental Impact Assessment (EIA).

At Blackstone Solicitors, we assist clients across England and Wales in navigating the legal requirements surrounding EIAs. This article explains what an EIA is, when it is required, and how construction companies can manage the process effectively to avoid delays and legal complications.

What Is an Environmental Impact Assessment (EIA)?

An Environmental Impact Assessment is a formal process used to evaluate the potential environmental consequences of a proposed development or project. The aim is to ensure that decision-makers consider environmental factors before granting planning permission.

The EIA examines factors such as:

  • Effects on local ecosystems and wildlife.
  • Pollution levels (air, water, noise).
  • Impact on natural resources.
  • Socio-economic and cultural implications.

The EIA process ensures that projects proceed in a sustainable manner and that potential adverse effects are mitigated wherever possible.

Legal Framework for EIAs

In England and Wales, the legal framework for EIAs is governed by the Town and Country Planning (Environmental Impact Assessment) Regulations 2017. These regulations implement the European Union’s EIA Directive, which continues to influence UK law despite Brexit.

The regulations outline the types of projects that require an EIA, as well as the procedures for conducting one.

When Is an EIA Required?

Not all construction projects require an EIA. Whether an assessment is needed depends on the type, scale, and location of the proposed development. The regulations categorise projects into two main schedules:

  1. Schedule 1 Projects

An EIA is mandatory for projects listed under Schedule 1 of the regulations. These include developments that are likely to have significant environmental impacts due to their size or nature. Examples include:

  • Waste disposal installations for hazardous waste.
  • Large-scale chemical plants.
  • Nuclear power stations.
  • Motorways and airports.

If your project falls under Schedule 1, an EIA must be completed as part of the planning application process.

  1. Schedule 2 Projects

For Schedule 2 projects, an EIA is required if the development meets certain thresholds and is likely to have significant environmental effects. Examples of Schedule 2 projects include:

  • Urban development projects (e.g., residential developments exceeding 5 hectares).
  • Infrastructure projects such as roads, railways, or pipelines.
  • Quarries and mining operations.
  • Energy production facilities, including wind farms and solar arrays.

The need for an EIA in Schedule 2 projects is determined through a screening process.

  1. Sensitive Locations

Even if a project does not meet the thresholds for Schedule 2, it may still require an EIA if it is located in an environmentally sensitive area. Sensitive locations include:

  • Sites of Special Scientific Interest (SSSIs).
  • National parks or Areas of Outstanding Natural Beauty (AONBs).
  • Special Protection Areas (SPAs) or Special Areas of Conservation (SACs).
  • World Heritage Sites.

The Screening Process

The first step in determining whether an EIA is required for a Schedule 2 project is to request a screening opinion from the local planning authority (LPA). The LPA assesses:

  • The characteristics of the project, including size, complexity, and potential emissions.
  • The sensitivity of the location.
  • The nature and scale of the potential environmental impacts.

The LPA will then decide whether the project is “EIA development,” meaning an EIA is required.

The Scoping Process

If an EIA is deemed necessary, the next step is scoping, which determines the key environmental issues to be assessed. Developers can request a scoping opinion from the LPA to identify:

  • The specific topics to be addressed (e.g., air quality, biodiversity, water management).
  • The methodology for conducting the assessment.

Scoping helps streamline the EIA process by focusing on the most significant environmental impacts.

Conducting the EIA

The EIA process typically involves the following steps:

  1. Baseline Studies

Baseline studies gather data on the existing environmental conditions of the site and surrounding area. This provides a benchmark for assessing potential impacts.

  1. Impact Assessment

The impact assessment evaluates the potential effects of the project on the environment, considering factors such as:

  • Noise and air pollution.
  • Habitat loss or fragmentation.
  • Water quality and hydrology.
  1. Mitigation Measures

Where adverse impacts are identified, the EIA must propose measures to mitigate or minimise these effects. For example, landscaping can reduce visual impacts, while noise barriers can address sound pollution.

  1. Environmental Statement

The findings of the EIA are compiled into an Environmental Statement (ES), which is submitted to the LPA as part of the planning application. The ES includes:

  • A description of the project.
  • Details of the baseline studies and impact assessment.
  • Proposed mitigation measures.

Public Consultation

The EIA process also involves public consultation. The Environmental Statement is made available for review, allowing stakeholders such as local residents, environmental groups, and statutory bodies to provide feedback.

The LPA must consider these responses when deciding whether to grant planning permission.

Consequences of Non-Compliance

Failing to comply with EIA requirements can have serious consequences for developers, including:

  • Rejection of the planning application.
  • Legal challenges from environmental groups or stakeholders.
  • Delays and additional costs.

In some cases, non-compliance can result in enforcement action, including project suspension or fines.

Minimising Delays and Risks

To avoid delays and legal complications, construction companies should:

  1. Engage Early with the LPA

Request screening and scoping opinions as early as possible to clarify EIA requirements and streamline the planning process.

  1. Work with Environmental Consultants

Engage qualified environmental consultants to conduct baseline studies and prepare the Environmental Statement. Their expertise ensures a thorough and accurate assessment.

  1. Seek Legal Advice

Consult with experienced solicitors, like those at Blackstone Solicitors, to navigate the legal complexities of the EIA process and address any disputes that arise.

  1. Implement Mitigation Measures

Plan for and implement mitigation measures from the outset to demonstrate your commitment to minimising environmental impacts.
