Clean air being a basic natural resource for every living thing  needs to be protected from any harmful effects of smoke and other air pollutants, hence an aggressive action is needed to maintain a good air quality .

Steps have been taken to control smoke emissions from industries and other sources in order to reduce the current levels of pollution.Different strategies and tactics have also been established i.e. the internal refuge programs for planning and monitoring resources and management programs which provide regulatory actions that are appropriate. These programs provide legal requirements for air quality together with directions and recommendations for working with regulatory agencies and how to manage the air resource. (Howell, 1999)There are several congress acts relating to the air resources which include: clean air act, the national environmental policy act of 1969 the wilderness act of 1964 and other statutes.

These laws enable the legislation to manage and protect the air resource and other values that depend upon good air quality.The clean air act (42 United States code (USO) 7401 et seq) preserves, enhances and protects refuge resources from air pollution damages and its related effects and also establishes programs that prevent deterioration of air quality in “clean air areas” of the country. (Howell, 1999)Similarly the congress also provides additional protection for class1 areas in section 169A of the clean air act specifying on a national goal of “remedying any existing and preventing any future manmade visibility impairment” in these areas.There maybe also additional state and air quality rules and regulations that must be complied within the jurisdictional boundaries of the agencies.

The best available control measures are taken to provide new emphasis for reducing emissions in designated areas. (Howell, 1999)ReferencesHowell, C. (1999); Air Quality and smoke Management; New York; Macmillan press
