Introduction This Practice Note covers environmental compliance related to onshore infrastructure projects in England and Wales. This is a complex area and there are many areas of regulation, ranging from the requirement for environmental assessment, site preparation issues, the need for environmental permits, licences and consents, measures relating to the avoidance of pollution, nature and biodiversity considerations, pollution controls, chemicals, energy efficiency and emissions. Requirements will vary depending on the type of project, location, scale and environmental sensitivity of the area. Additional regimes will also need to be complied with which are beyond the scope of this Practice Note, eg planning requirements will need to be followed and necessary building controls and design and safety standards will need to be complied with, as well as applicable health and safety legislation, highways and utilities requirements and landowner/third party rights.
