6.63 The National Waste Strategy, launched in December 1999 by the Scottish Environmental Protection Agency (SEPA), provides the basis on which an integrated approach to waste management can be developed to ensure that, in future, waste is managed in a more sustainable way. Local authorities are expected to support the Strategy by using statutory planning powers to assist SEPA in facilitating the necessary network of facilities identified by the national strategy and Area Waste Plans. (The Glasgow and the Clyde Valley Area Waste Plan has been approved). The Joint Structure Plan does not identify Glasgow as an area of search for new landfill facilities.
