(Environmental Protection Act, EPA)

¹ If sev­er­al sources of air pol­lu­tion cause or are ex­pec­ted to cause harm­ful ef­fects or nuis­ances, the au­thor­ity con­cerned must draw up a plan of the meas­ures that will con­trib­ute to re­du­cing or elim­in­at­ing these ef­fects with­in a set time (ac­tion plan).

² Ac­tion plans are bind­ing for the au­thor­it­ies that are en­trus­ted with en­force­ment by the can­tons. They must make a dis­tinc­tion between meas­ures which may be ordered im­me­di­ately and meas­ures for which the leg­al frame­work still has to be en­acted.

³ If a plan provides for meas­ures which come with­in the area of re­spons­ib­il­ity of the Con­fed­er­a­tion, the can­tons must make the ne­ces­sary ap­plic­a­tions to the Fed­er­al Coun­cil.
