C6.5 Stages of Environmental Impact Assessment


EIA Process

The EIA process is similar to that of an Environmental Management System (EMS) in that it is of an iterative nature. The steps within an EIA should be completed as a series of feedback loops, allowing the development proposal to be amended and improved.

The EIA process is demonstrated in the diagram below:

The first stage is to determine if an EIA is required. This is known as Screening.

Once it has been determined that an EIA is required, it must be agreed what information is required within the EIA. This is known as Scoping.

The negative environmental impacts associated with the development should be eliminated or controlled. This is referred to as Mitigation.

An Environmental Statement is produced by the Developer and assessed by the Local Authority. It is a summary of the EIA findings.
