The document discusses Philadelphia's efforts to address littering issues in the late 1980s and early 1990s. In 1989, Philadelphia began enforcing anti-littering laws more strictly but continued to be called "Filthydelphia" in 1990. A new newsletter called "Clean Slate" launched with the goal of eliminating this nickname by getting residents more involved in cleaning the city. Various initiatives like annual clean up competitions and expanding recycling programs were discussed as ways to engage the community and make Philadelphia cleaner.
