From April 4th to noon on May 30th 2012, HS2 Ltd are running a Scoping and Methodology consultation for the Environmental Impact Assessment.
The Dft’s website says
“The purpose of this scoping is to define those environmental topics that should be assessed as part of the EIA, the methods that are to be used and the geographic and temporal scope of the EIA. The Scope and Methodology report is intended to establish the overall approaches that should be taken during the Environmental Impact Assessment of the HS2 project rather than dealing with local level issues and considerations.”
You can download the document from their website.
If you think you may be affected by the later phases, you need to respond now, as it may form the basis for the EIA for the route north of Birmingham.
The following articles are relevant to different consultations HS2 Ltd have held, but possibly not the current ones.
