Environmental Impact Assessment

TLC will be subject to a comprehensive and stringent Environmental Impact Assessment (EIA).

We recognise that a development of this scale doesn’t come without impacts.  Accordingly, we seek to understand potential environmental impacts as early as possible in the project development cycle and go beyond the mandatory requirements for gathering environmental evidence.   When combined with an iterative development process this allows us to identify any concerns, minimise significant environmental effects and mitigate through design changes to project.

In addition we have established an Ecosystems Enhancement Programme (EEP); an initiative designed to take a strategic approach to addressing environmental challenges and to deliver a net positive outcome for biodiversity. To find out more, take a look at the EEP pages of our website.

Key features of this combined approach to the environment are as follows:

 

Evidence Plan

Through the adoption of an ‘Evidence Plan’ approach we are bringing together statutory and non-statutory regulators to agree the scope, methodology and necessary output of environmental surveys and impact assessments. Informed by this engagement, and the collation of pre-existing data from survey work conducted over the last 20 years, our team has initiated a programme which will assess:

  • Intertidal & subtidal ecology,
  • Birds, fish (including commercial and recreational fisheries) & marine mammals
  • Coastal processes modelling informing further work sediment transport, water quality, flooding & water resources, coastal erosion, navigation & marine transport
  • Land use & hydrology
  • Terrestrial ecology
  • Seascape & landscape
  • Marine & terrestrial noise & vibration
  • Air quality
  • Onshore transport, tourism & recreation, & socio-economics
  • Marine & terrestrial cultural heritage.

 

Independent Peer Review Groups

Through the establishment of Independent Peer Review Groups for fish and coastal processes to review all aspects of our work, we aim to ensure that we achieve high quality, independent and authoritative outputs, which are accepted by regulators and other key stakeholders including the public.

 

Early work

We have a lot more work to do but some of the surveys which are in the process of being completed are:

  • Bird tracking
  • Plankton
  • Targeted intertidal sampling (saltmarsh, seagrass, sabellaria, hard substrate)
  • WFD intertidal invertebrate sampling
  • IBM intertidal invertebrate sampling & analysis
  • Fish surveys
  • Intertidal sediment transects
  • Initial sediment sampling
  • Water quality sampling
  • Aerial imagery/topography surveys
  • Oceanographic deployments
  • Geophysical surveys
