Since what date has it been illegal to vent substitutes for CFC and HCFC refrigerants?

November 15, 1990
November 15, 1995
November 15, 2000
November 15, 2005

The correct answer is: November 15, 1995

The correct choice is based on significant legislative changes that took place in response to the environmental impact of certain refrigerants. It became illegal to vent substitutes for CFC (chlorofluorocarbon) and HCFC (hydrochlorofluorocarbon) refrigerants effective from November 15, 1995. This action was part of the broader initiatives established under the Clean Air Act and the Montreal Protocol, aimed at reducing substances that deplete the ozone layer. The 1995 regulation addressed the growing awareness and concern about the harmful effects of refrigerants that contribute to ozone layer depletion and global warming. This date marks a critical point in environmental regulations, emphasizing the importance of adhering to practices that minimize harm to the atmosphere.
