(EU) 2015/2193
"This Directive lays down rules to control emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and dust into the air from medium combustion plants, and thereby reduce emissions to air and the potential risks to human health and the environment from such emissions. This Directive also lays down rules to monitor emissions of carbon monoxide (CO)."
"This Directive shall apply to combustion plants with a rated thermal input equal to or greater than 1 MW and less than 50 MW (‘medium combustion plants’), irrespective of the type of fuel they use. This Directive shall also apply to a combination formed by new medium combustion plants pursuant to Article 4, including a combination where the total rated thermal input is equal to or greater than 50 MW, unless the combination forms a combustion plant covered by Chapter III of Directive 2010/75/EU."
"Member States shall lay down the rules on penalties applicable to infringements of the national provisions adopted pursuant to this Directive and shall take all measures necessary to ensure that they are implemented."
