Regardless of whether they concern developing regional master plans for managing non-hazar dous industrial, medical and pharmaceutical, residual, agricultural and inert waste or provincial/prefectural master plans for managing household and similar waste - or even the development of controlled landfills - the national guidelines primarily address methods of organizing and implementing these tools, but hardly touch on technical and environmental requirements. Legislation requires annual control of watercourses that could have been affected by any landfill leachate, but does not mention which parameters need to be analysed or their limit values. The same applies for water pollution, as no parameters or limit values are mentioned.
