Environmental Impact Assessments

Understanding the impact of planed work on the environment.

Calculate Impacts

What is the objective impact of a given process or plan.

Assess Effects

How will these impacts have an effect on the wider environment.

Mitigate

How can we control emissions to a point of no observed effect.

Broadly speaking, an environmental impact assessment seeks to understand the environmental effects that may be realised as a result of a given development, programme of works, or proposed plan.

Broadly speaking, an environmental impact assessment seeks to understand the environmental effects that may be realised as a result of a given development, programme of works, or proposed plan. The primary legislation governing the process of environmental impact assessment in England is the Town and Country Planning (Environmental Impact Assessment) Regulations 2017.

Noise Impact Assessments

The institute of Environmental Management and Assessment have published guidelines that proved to be a key resource in assisting the assessment of the impact of potential new noise sources. In particular, the guidelines include advice on the various factors that should be considered during the NIA process including: how to scope a noise assessment, defining the baseline environment, and prediction and impact of future changes. Information about the many facets of a noise assessment as also discussed in detail.

The content of these guidelines apply equally to formal assessments required under legislation, such Environmental Impact Assessment Regulations described above, as to noise assessments needed to support a routine planning application.

Understanding Impacts and Effects

Noise Impact The difference in the acoustic environment before and after the implementation of the proposals (also known as the magnitude of change). This includes any change in noise level and in other characteristics/features, and the relationship of the resulting noise level to any standard benchmarks.

Noise Effect The consequence of the noise impact. This may be in the form of a change in the annoyance caused, a change in the degree of intrusion or disturbance caused by the acoustic environment, or the potential for the change to alter the character of an area such that there is a perceived change in quality of life. This will be dependent on the receptor and its sensitivity.

Significance of Effect The evaluation of the noise effect and, particularly if the noise impact assessment is part of a formal EIA, deciding whether or not that impact is significant.
