Ambient air quality management and environmental noise pollution management are the major functions of this unit. Preparation of standards and regulations required to manage the ambient air quality in the country is essential and this unit is totally involved in preparation and review of ambient air quality standards, vehicular emission standards, industrial source emission standards, industrial noise standards, vehicle horn noise standards and vibration standards required to control the environmental damage due to air pollution and noise pollution in the country.
Also the scientific staff working in the unit involve in implementation of the above regulations by issuing compliance monitoring reports to other divisions of the authority and other organizations as well. In addition to that officers provide expert evidence and test reports to courts.
Ambient air quality monitoring has been carried out at Colombo Fort Air Quality Monitoring Station since 1998 and the unit posses the good air quality data base collected from the year 1998.
Vehicle emission testing program is implemented to control air pollution caused by vehicles and officers of this section closely monitor the vehicle emission testing program and VET centres on regular basis to make it public benefitted program through controlling air pollution caused by vehicles.
In the mean time unit is planning to expand its testing facilities to test the quality of fossil fuels since the major sources of air pollution is poor quality fossil fuels used in transport sector , power generation and industrial activities. Expansion of testing facilities will help us to check the compliance of fuel quality with existing emission related standards published under NEA.
In addition to above major activities, unit is involved in trans boundary air pollution monitoring by carrying out the activities coming under Male Declaration Framework. It’s objective is to identify and control air pollutants moving from one country to another country. In Sri Lanka the air quality monitoring unit of the Central Environmental Authority is engaged in continuously monitoring the arrival of air pollutants from other countries. This monitoring site is located at Doramadalawa in Mihinthale.
