Paragraph 14 Navigational lights, buoys, etc.I1

In addition to any requirement under articles 19 (lights on tidal works etc. during construction) and 21 (permanent lights on tidal works), the undertaker, at or near every tidal work, and any other work of which the undertaker is in possession in exercise of any of the powers conferred by this Order (being in either case a work which is below the level of high water forming part of the river), must exhibit such lights, lay down such buoys and take such other steps for preventing danger to navigation as the Tees Port Authority may from time to time reasonably require.
