State by State Clean Air Laws and Statutes
Last Updated on July 15, 2021
The COVID-19 pandemic necessitated many lifestyle changes, including wearing masks, social distancing and choosing outdoor activities over indoor ones. Many people took these precautions in an effort to avoid the virus and ended up avoiding the cold and flu season, too. At a time with increased emphasis on indoor air quality, Air Oasis is proud to offer air purifiers for any space and every concern.
Amid the return to the physical workspace, some companies are prioritizing their employees’ health by providing air purifiers for the office. The Occupational Safety and Health Administration (OSHA) requires employers to provide a safe and healthy workplace and urges employers to follow the guidelines laid out by the Centers for Disease Control and Prevention (CDC), which includes the use of air purifiers.
In addition to enforcing workplace air quality laws, the federal government regulates National Ambient Air Quality Standards. The Environmental Protection Agency (EPA) sets federal standards for air quality with laws like the Clean Air Act.
History of Clean Air Act and Amendments
More than 50 years ago, the United States Congress passed the 1970 Clean Air Act in an effort to control common industrial pollutants like sulfur dioxide and nitrogen oxides. The passage of the act and its subsequent amendments dramatically improved air quality across the country. In 1990, Congress passed sweeping amendments that addressed acid rain, urban air pollution and toxic emissions. Each state in the country must comply with the regulations laid out in the Clean Air Act.
Despite the vast improvement, recent data shows an uptick in air pollution once again. After declining by more than 24% from 2009 to 2016, fine particulate matter (in counties with monitors across the U.S.) increased 5.5% from 2016 to 2018, indicating the necessity of continued efforts in mitigating air pollution.
Although the Clean Air Act regulates ambient air quality, it doesn’t regulate indoor air quality. Indoor air quality is regulated on a state-by-state basis. Outdoor pollution can be a primary cause of indoor air problems, which itself varies by state. One regulatory body is at the forefront of clean air efforts.
Office of Air and Radiation (OAR)
The Office of Air and Radiation (OAR) is responsible for administering the Clean Air Act and developing policies, national programs and regulations to control pollution and radiation exposure. OAR isn’t only concerned with outdoor air quality; the organization works to improve indoor air quality as well.
After compiling data on air pollution, OAR reports its findings to Congress and makes that information available to the public. The organization assists state and local agencies by monitoring air pollution and developing regulations to improve air quality.
