6.—(1) For the purpose of determining whether a duty under Regulation 3 or a power under Regulation 4, as the case may be, has arisen with respect to an eligible building, the prevailing noise level, the relevant noise level and the effective contribution to the relevant noise level made by noise caused or expected to be caused by traffic using or expected to use a highway shall be ascertained in accordance with the advice and instruction contained in the technical memorandum entitled “Calculation of Road Traffic Noise” published by Her Majesty's Stationery Office (1975).

(2) The appropriate highway authority for a highway to which Regulation 3 applies shall ascertain every eligible building in respect of which a duty under that Regulation has arisen and shall prepare a map or list, or both, identifying every such building.

(3) Any such map or list shall be deposited at the office of the appropriate highway authority or their agent nearest to the buildings identified therein and made available for public inspection during the hours when the office is open, not later than six months after the relevant date or, if the relevant date was before the commencement date, not later than six months after that date.
