With regards an inconsistency between the Rule 8 letter and Annex A. The letter states that 21st- 23rd June are the reserved dates for issue specific hearings, whilst Annex A states that its 19th-21st June.
These dates are subject to confirmation at a later date (or may not be used at all) but can it be confirmed which of the two is intended to be the reserved dates?

The dates in the Annex of the Rule 8 letter (ie 19-21June) are the correct ones that we want people to reserve. A letter about this will be sent to all Interested Parties, by 11 May 2012 (the deadline set in the Annex of the Rule 8 letter).
Unless the Examining Authority otherwise directs, the applicant must also publicise the hearings in accordance with Rule 13 of the Infrastructure Planning (Examination Procedure) Rules 2010 and this notice would be published on the Planning Inspectorate's website.
