For the present study, issue of air pollution is considered. In the current environment, the air pollution is growing every day and has become a very bigissue throughout the world.For reducing the air pollution various actions have been implemented by government of USA (Schnelle Jr, Dunn and Ternes, 2015). In this aspect, Clean Air Act has been introduced and as a consequence to it there were drastic changes occurred in the environment as air pollution has been reduced and it prevented thousands of life’s getting affected from severe health effects. As per the survey of Manhan (2017), it was examined that throughthe implementation of Clean Air Act, sixcommon pollutants were dropped up to 73% between 1970 and 2017. As of EPA and Clean Air Act multiple problems of air pollutions have been solved. The programs that are carried for making solutions are based on latest technology andscience.They started working with state, tribunal and local governments, and various other federal agencies as well as investors to overcome with the issue of air pollution and made an efforts to reduce the damages caused by it. In spite of continuous efforts have been make to control the air pollution there are various issues hinders in between due to which Americans have to face various health and welfare problems. Major challenges associated with the same are conventional air pollution, climate change and ozone layer depletion(Devinny, Deshusses and Webster, 2017). To cope up with the same, in the present phase standards were revised by the EPA for 5-6 usual contaminants to match the national standards of air quality.The standards created move protective norms for resolving the issue as new and analyzed facts indicates that available standards are not appropriate for protecting the health and surroundings. .
