Functions of CPCB comes under both national level and as State Boards for the Union Territories. CPCB, under the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, aims to promote cleanliness of streams and wells in different areas of the States by prevention, control and abatement of water pollution, and to improve the quality ...
Emission standards for light-duty diesel vehicles (GVW ≤ 3,500 kg) are summarised in Table 4. Ranges of emission limits refer to different classes (by reference mass) of light commercial vehicles; comparable to EU light-duty vehicle emission standards. The lowest limit in each range applies to passenger cars (GVW ≤ 2,500 kg; up to 6 seats).
Regulations that define and limit the concentration of pollutants in the ambient air or in gaseous emissions to the ambient air are issued by various national and state (or provincial) environmental protection and occupational health and safety agencies. Such regulations involve a number of different expressions of concentration.
Air pollution emission source. Types of air pollutant emission sources – named for their characteristics Sources, by shape – there are four basic shapes which an emission source may have. They are: Point source – single, identifiable source of air pollutant emissions (for example, the emissions from a combustion furnace flue gas stack ...
An emission performance standard is a limit that sets thresholds above which a different type of vehicle emissions control technology might be needed. While emission performance standards have been used to dictate limits for conventional pollutants such as oxides of nitrogen and oxides of sulphur (NO x and SO x ), [ 3 ] this regulatory ...
The city should set limits on emissions from certain buildings, using an approach already in place in New York, according to the report from the Urban Land Institute Chicago.
For example, such a regulation might limit the concentration of NOx to 55 ppmv in a dry combustion exhaust gas corrected to 3 volume percent O 2. As another example, a regulation might limit the concentration of particulate matter to 0.1 grain per standard cubic foot (i.e., scf) of dry exhaust gas corrected to 12 volume percent CO 2.
An emission inventory (or emissions inventory [1]) is an accounting of the amount of pollutants discharged into the atmosphere.An emission inventory usually contains the total emissions for one or more specific greenhouse gases or air pollutants, originating from all source categories in a certain geographical area and within a specified time span, usually a specific year.
