Article 2.5.2.2.2.

§ 1.

The Flanders Environment Agency shall assess the air quality in all zones and agglomerations for the polluting substances stated in Article 2.5.2.2.1, in accordance with the criteria stated in paragraphs 2, 3 and 4, and in accordance with the criteria listed in Appendix 2.5.3.3.

 

§ 2.

In all zones and agglomerations where the level of the polluting substances stated in paragraph 1 exceeds the established upper threshold limit for those polluting substances, fixed measurements shall be used to assess the air quality. These fixed measurements may be supplemented with modelling techniques or indicative measurements to obtain adequate information on the spatial distribution of the air quality.

 

§ 3.

In all zones and agglomerations where the level of the polluting substances stated in paragraph 1 is lower than the established upper threshold limit for those polluting substances, a combination of fixed measurements and modelling techniques or indicative measurements may be used to assess the air quality.

 

§ 4.

In all zones and agglomerations where the level of the polluting substances stated in paragraph 1 is lower than the established lower threshold limit for those polluting substances, modelling techniques or objective estimation techniques or both shall suffice to assess the air quality.

 

§ 5.

Besides the assessments stated in paragraphs 2, 3 and 4, measurements shall be carried out at background locations in rural areas, located a certain distance from major sources of air pollution. These measurements shall at least provide information on the total mass concentration and the concentrations of the chemical compounds of fine particulate matter (PM2.5) in terms of the annual average, and shall be carried out in accordance with the following criteria:

a sampling point shall be established for every 100,000 kmē;

2° 

at least one measuring station or, by mutual agreement with the neighbouring countries, one or more joint measuring stations shall be established that cover the relevant neighbouring zones, to guarantee the required spatial resolution;

if applicable, the monitoring shall be coordinated with the monitoring strategy and the measuring cooperative programme for monitoring and evaluation of the long-range transmissions of air pollutants in Europe (EMEP);

Parts A and C of Appendix 2.5.3.1 apply to the data quality targets for measurements of mass concentrations of particulate matter, and Appendix 2.5.3.4 applies in its entirety.

 

The Flanders Environment Agency shall inform the European Commission through the appropriate channels of the measuring methods used to measure the chemical composition of fine particulate matter (PM2.5).
