Hydrogeology and Soils

There are no designated sites, for example Sites of Special Scientific Interest or Geological Conservation Review Sites within the study area that are designated for their geological or geomorphological importance.
Potential effects as a result of the proposed CTLR Project during construction include:
- Accidental release, leakage or spillages of hydrocarbons, chemicals, fuel or oils from storage tanks or construction plant during construction causing contamination of groundwater;
Localised increase in alkalinity from spillages of concrete or unset cement; and
Potential contamination of the water environment due to the disturbance of contamination associated with construction works and in particular deep excavations (e.g. bridge foundations, deep utility excavations), or the mobilisation of contaminants due to groundwater pumping.
The potential operational effects stated above on hydrogeology and soils are expected to occur (or continue to occur) once the proposed CTLR Project is in operation.
Mitigation measures for the construction phase will comprise standard good construction practices covered by a Construction Environmental Management Plan (CEMP) produced by the Contractor. Mitigation measures for the operational phase will be subject to detailed design. An outline CEMP (Appendix 2.2 of the EIAR) has been prepared as part of this EIA and forms part of the planning application submission.
The recommended mitigation measures during the construction of the proposed CTLR Project are considered sufficient to minimise the identified potentially significant effects on sensitive receptors to a non-significant level.
In summary, based on the currently available information no significant adverse residual or cumulative effects have been predicted.
