The Highway Litter Clearance and Cleaning (Transfer of Duties) Order 1991
Section 89(1)(a) and (2)(a) of the Environmental Protection Act 1990 places a duty on the council of each district, or in Greater London each London borough, to ensure that land comprised in the highways maintainable at the public expense within its area (other than trunk roads which are special roads) are so far as practicable kept clean and clear of litter and refuse. Section 86(11) empowers the Secretary of State to transfer responsibility for the discharge of these duties as respects all or any part of such a highway to the highway authority for that highway.
