The complainant has requested information from Thames Water Utilities Ltd (Thames Water) about ground water levels regarding the proposed Abingdon Reservoir. Thames Water refused to provide the requested information, applying regulation 12(4)(d) of the EIR – material still in the course of completion. The Commissioner’s decision is that the exception at regulation 12(4)(d) of the EIR is engaged and that the public interest favours non-disclosure. The Commissioner does not require further steps.
