The case goes back to 2016 when the European Commission sued Poland for the EU Court for failing to comply with EU air quality legislation. Too high concentrations of dust in the air poses a serious threat to public health – Brussels then warned.
The Commission accused Poland of exceeding the daily standards for PM10, the lack of appropriate measures set out in air protection programs and the incorrect implementation of the EU directive on air quality. These regulations say that in the case of exceeding the limit values, air protection programs are to determine such activities that the period of exceedances is as short as possible.
