Thames Tideway Tunnel
Further to the discussion at the Preliminary Meeting, Thames Water submitted sample noise contour plans (attached) for advice as to whether, in this form, the material was likely to be useful to the ExA in consideration of this topic.
The Planning Inspectorate advised that the T period should be shown on the drawings, consistent with BS5228, and with reference to the night noise contours it should be confirmed by the applicant that the night contour levels shown are for the nights when there is working at a site and not an average including nights where there is no working. The Planning Inspectorate also asked for consistency between the night and daytime noise contour levels so they could be directly compared.
The applicant was also advised that the Panel may seek further clarification about the noise contour plans during the course of the examination, which may require further iterations of the noise contour plans to be submitted.
