What is normal ambient air?

Safeopedia explains that ambient air is atmospheric air in its natural state, not contaminated by air-borne pollutants. Ambient air is typically 78% nitrogen and 21% oxygen. The extra 1% is made up of a combination of carbon, helium, methane, argon and hydrogen.

What is the Texas Clean Air Act?

The original Texas Clean Air Act (“TCAA”) was enacted in 1965, and had as its purpose the safeguarding of state air resources and protection of the health, general welfare and physical property of the people. The Texas Air Control Board was then assigned to carry out these mandates.

Which is standard is used for ambient air quality monitoring?

Under the provisions of the Air (Prevention & Control of Pollution) Act, 1981, the CPCB has notified fourth version of National Ambient Air Quality Standards (NAAQS) in 2009. This revised national standard aims to provide uniform air quality for all, irrespective of land use pattern, across the country.

What is causing air pollution in Texas?

Pollutant levels are driven by many sources including: tailpipe emissions from cars, trucks and buses; toxic pollutants emitted into the air by more than 400 chemical manufacturing facilities, including 2 of the 4 largest refineries in the U.S.; the petrochemical complex along the Houston Ship Channel and the Port of …

Does Texas have clean air?

What are the sources of air pollution in Texas? Texas is known for its blue skies and bright summer days. However, hot weather and pollutants from cars, trucks, and factories can make the air dirty and unhealthy, especially for Texans who are sensitive to air pollution.

How is ambient air measured?

Ambient levels are the actual concentration of a pollutant in the air. They are usually reported in parts per million (ppm), parts per billion (ppb), or micrograms or nanograms per cubic metre (µg or ng/m3).

What is EPA’s guideline on air quality models?

What are the air quality control control tables for?

The tables also indicate which air quality planning areas are affected by each control measure. Controlling Emissions from Stationary Sources has more detailed information on the stationary-source air quality rules for specific areas and for specific pollutants.

What is air quality science and policy?

Air Quality Research – Programs are designed to improve the state of air quality science and policy including air quality modeling and studies on air toxics, flares, pollutant concentrations near Texas roadways, emissions inventory, atmospheric chemistry, and meteorology.

What is air quality modeling?

Air Quality Modeling – Scientists use computer models to predict how air quality will be affected by meteorological conditions, chemical reactions, economic and population growth, and reduced emissions.
