Since what date has it been illegal to vent substitutes for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs)?

January 1, 1990
November 15, 1995
March 1, 2000
June 1, 2005

The correct answer is: November 15, 1995

The correct choice reflects the significant regulatory change established by the Clean Air Act Amendments of 1990 and the subsequent regulations by the Environmental Protection Agency (EPA). Specifically, it has been illegal to vent substitutes for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) since November 15, 1995. This date is crucial because it marked the implementation of the EPA's regulations aimed at protecting the stratospheric ozone layer. CFCs and HCFCs are known ozone-depleting substances, and regulations were established to reduce the emissions of these chemicals into the atmosphere. The venting of these substances contributes to ozone layer depletion and poses environmental risks, leading to increased regulations. The choice of dates prior to November 15, 1995, such as January 1, 1990, and March 1, 2000, does not align with the specific legislative and regulatory milestones set forth for venting prohibitions. Furthermore, June 1, 2005, came after the definitive date of venting prohibition and was not the inception of these regulations. Understanding this context helps recognize the importance of regulatory compliance concerning ozone-depleting substances and the timeline
