When did the EPA start regulating emissions?
1970
Since 1970, EPA has set and implemented emissions standards to control pollution from everything from passenger vehicles, heavy duty trucks and buses, construction and farm equipment, locomotive and marine engine and even lawn and garden equipment.
What decade did car manufacturers introduce devices?
The general strategy of automobile engineers for meeting California standards in the 1960s and federal standards in the first half of the 1970s was to add devices to the car to catch, and often reburn or chemically transform, unwanted exhaust and emission gases22.

Is the Clean Air Act still in effect?
Trump administration ends EPA clean air policy opposed by fossil fuel companies. WASHINGTON — The Trump administration announced Thursday it is doing away with a decades-old air emissions policy opposed by fossil fuel companies, a move that environmental groups say will result in more pollution.
What is the meaning of RA 8749?
Philippine Clean Air Act
Republic Act No. 8749, otherwise known as the Philippine Clean Air Act, is a comprehensive air quality management policy and program which aims to achieve and maintain healthy air for all Filipinos.
What was the first air pollution control device?
Scrubbing systems are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which it continues to be used to this day.
How are pollution control systems used in this day and age?
In this day and age, pollution control systems are a must. Air pollutants are generated through both natural—e.g., volcanic eruptions and wildfires—and human-made sources—including mobile and stationary ones.
What are the different types of pollution control equipment?
Table 4 – Additional Considerations and Restrictions for Air Pollution Control Equipment Type of Control Equipment Device Considerations and Restrictions Scrubbers – Dry Scrubbers Gas streams should be cooled and diluted Wet Scrubbers Liquid reagent must come into direct con Air Filters –
How are dust catchers used to control air pollution?
The first four control devices control the amount of particulate matter escaping into the environment while scrubbers control the acidic gas emissions into the atmosphere. The principle of a dust catcher is shown in Fig 1.
How are industrial air pollution control devices used?
Some of the most commonly used air pollution control devices in manufacturing and processing facilities, industrial air scrubbers employ a physical process—i.e., scrubbing—which removes particulates and gases from industrial emissions, such as smokestack exhaust (in the case of exhaust air scrubbers ), before they are released into the atmosphere.
In this day and age, pollution control systems are a must. Air pollutants are generated through both natural—e.g., volcanic eruptions and wildfires—and human-made sources—including mobile and stationary ones.

What was the name of the first air pollution control district?
The phenomenon was termed a “gas attack” and blamed on a nearby butadiene plant. But when the plant was shut down, the smog did not abate. In 1947, the Los Angeles County Air Pollution Control District – the first such body in the nation – was formed.
