Planning Timeline for Long Term Solution at Rogerstown
• IROPI (Imperative Reasons of Overriding Public Interest) review – Approximately 7 weeks (i.e. delivery on / before 1st July). However, part of the review will be part-dependent on receiving information in a timely manner from various Government agencies, which is somewhat beyond our control.
• EIA Scoping report – Approximately 7 weeks (i.e. delivery on / before 1st July). This may require elements from our numerical modelling assessment and refinement of the proposed option.
• Numerical Assessment and Refinement of Proposed Option, including assessment of potential impact– Approximately 10 weeks (i.e. around mid July).
• Preparation of Planning Report/Statement of Case/ Justification/Mitigation/Possible Compensatory Measures for submission to An Bord Pleanála in 2021
