The analysis is presented within this report, and it is required as per article 4(2)(h) of the Town and Country Planning (Border Facilities and Infrastructure) (EU Exit) (England) Special Development Order 2020. The objective of this analysis is to identify any likely adverse or beneficial significant environmental effects as a result of the scheme, and where relevant outline the measures incorporated in the scheme design and delivery methods to avoid, eliminate or reduce what might otherwise have been significant adverse environmental effects. Chapter 2 of this report describes the physical characteristics and location of the scheme. Chapter 3 of this report describes the environmental baseline, environmental constraints, sensitivity of the environmental receptors and the potential environmental effects of the scheme. The analysis has been undertaken in accordance with the guidance provided in the Sustainability and Environmental Sections of the Design Manual for Roads and Bridges (DMRB). As the scheme is principally a transport related project, and as such, the DMRB provides the most appropriate published guidance for undertaking the analysis of environmental effects. Additional discipline specific guidance has also been applied where relevant, in order to provide a robust analysis of the effects. Relevant guidance is referenced for each discipline in Chapter 3 of this report. 1.2 Screening under the Environmental Impact Assessment (EIA) Regulations The Town and Country Planning (Environmental Impact Assessment) Regulations 2017 (as amended) (‘the EIA Regulations’) set out procedures for determining whether or not development is ‘EIA Development’ for which an Environmental Statement must be prepared to accompany a planning proposal. The EIA Regulations defines ‘EIA Development’ as either: (a) “Schedule 1 development; or, (b) Schedule 2 development likely to have significant effects on the environment by virtue of factors such as its nature, size or location.” Regulation 2(1) defines ‘Schedule 2 development’ as: “Development, other than exempt development, of a description mentioned in Column 1 of the table in Schedule 2 where – (a) Any part of the development is to be carried out in a sensitive area; or, (b) Any applicable threshold or criterion in the corresponding part of Column 2 of that table is respectively exceeded or met in relation to that development.” The scheme does not comprise development listed under Schedule 1 of the EIA Regulations.
