Environmental Impact Assessment (EIA)

An Environmental Impact Assessment (EIA) provides a structured assessment of the environmental effects associated with certain development proposals. It considers the likely significant effects of a project and identifies appropriate measures to avoid, reduce or manage those impacts.

Our consultants provide EIA support for development projects where environmental assessment is required or where a coordinated assessment is appropriate to the scale and characteristics of the scheme.

Environmental Baseline Assessment

EIA begins with an understanding of the existing environmental conditions. Depending on the project, this can include ecology, air quality, noise, transport, water, landscape, climate and other environmental factors.

Establishing a robust baseline provides the foundation for assessing how the proposed development could change the surrounding environment.

Environmental Impact Assessment

We assess the potential environmental effects associated with construction and operation of the proposed development.

The assessment considers the characteristics of the project, the sensitivity of affected receptors and the likely significance of identified impacts.

Mitigation and Environmental Management

Where impacts are identified, the EIA process considers measures that can avoid, reduce or manage them.

We work with the wider design team to develop mitigation that is practical, proportionate and capable of being incorporated into the project.

Coordinated Planning Support

EIA can involve multiple technical disciplines and a significant volume of supporting evidence. Our multidisciplinary approach allows environmental considerations to be coordinated across the project rather than assessed in isolation.

This helps provide planning authorities with a clear understanding of the environmental implications of the proposed development.

Supporting Sustainable Development

A well-managed EIA provides decision-makers with evidence about environmental effects and the measures proposed to address them. It can also help development teams identify opportunities to improve environmental performance as the scheme evolves.

Our Environmental Impact Assessors Can Help

The Syntegra Group’s Environmental Impact Assessment consultants offer an enviable level of Environmental Impact Assessment experience for your project, with a thorough understanding of the planning system and the procedural and technical aspects of environmental impact assessment.

Through our depth of knowledge and experience of delivering environmental impact assessment projects, our ability does not only lie with the technical aspects of the work, we will also advise on the cost of an EIA, project risks (both financial and programme risks) and procurement strategy.

Our involvement ranges from the early feasibility to post application stages, including Public Inquiry work, and the discharging of planning conditions with sensitivity towards cost and programme implications.

Our EIA consultants’ experience also includes renewable energytransport and water resource projects, housing and mixed used developments, mineral extraction, Phase 1 land contamination and waste management.

Question: What is an Environmental Impact Assessment?

Answer: An Environmental Impact Assessment (EIA) is a statutory process that identifies, predicts and evaluates the likely significant environmental effects of a proposed development before planning permission is granted. In England it is governed by the Town and Country Planning (Environmental Impact Assessment) Regulations 2017. The findings are reported in an Environmental Statement submitted with the planning application.

EIA ensures that decision-makers and the public understand the environmental consequences of a development and that mitigation is secured through the planning process.

 

Question: Which developments require an EIA?

Answer: The Regulations divide development into Schedule 1 projects, for which EIA is always required, such as large power stations, refineries and major infrastructure, and Schedule 2 projects, for which EIA is required where the development is likely to have significant environmental effects. Schedule 2 includes urban development projects above thresholds such as 150 dwellings, 5 hectares or 1 hectare of non-residential floorspace, industrial estates, infrastructure and developments in sensitive areas. A screening opinion from the Local Planning Authority determines whether EIA is required.

 

Question: What is EIA screening?

Answer: Screening is the process by which the Local Planning Authority decides whether a Schedule 2 development requires EIA. The developer may request a screening opinion, providing a description of the development and its likely effects. The authority must respond within three weeks and take account of the characteristics of the development, its location and the type of potential impact. A negative screening opinion avoids the cost and time of a full EIA.

 

Question: What is EIA scoping?

Answer: Scoping is the process of agreeing with the Local Planning Authority and statutory consultees which environmental topics need to be assessed in the Environmental Statement, the methodologies to be used and the baseline information required. A scoping opinion is provided within five weeks of a request. Effective scoping focuses the EIA on the significant issues and avoids unnecessary assessment.

 

Question: What does an Environmental Statement contain?

Answer: An Environmental Statement typically includes:

  • Description of the development and reasonable alternatives considered
  • Baseline environmental conditions
  • Technical chapters on topics such as air quality, noise and vibration, ecology, daylight and sunlight, wind microclimate, transport, flood risk and drainage, landscape and visual, heritage, ground conditions, climate change and socio-economics
  • Assessment of cumulative effects with other developments
  • Mitigation and residual effects
  • A non-technical summary

The Statement must be prepared by competent experts and is subject to a statutory 30-day consultation period.

 

Question: How long does an EIA take?

Answer: The EIA process typically takes six to twelve months, driven by seasonal survey requirements, baseline monitoring, scoping consultation and the preparation of technical chapters. The determination period for EIA applications is 16 weeks rather than 13. Early commissioning and coordination of surveys is essential to avoid the EIA delaying the planning programme.

 

Question: Why choose Syntegra Group for Environmental Impact Assessment?

Answer: Syntegra Group provides EIA screening and scoping, EIA coordination and the preparation of technical chapters for air quality, noise and vibration, ecology, daylight and sunlight, wind microclimate, flood risk and drainage, energy and climate change, and lighting. Because these disciplines are provided in-house, we coordinate baseline surveys, methodologies and cumulative assessments efficiently and deliver consistent, robust Environmental Statements that satisfy Local Planning Authorities and statutory consultees.
