<s>[INST] The next text is a question of a member of the European parliament:"Directive2008/50/EC on ambient air quality and cleaner air for Europe establishes limit values for particulate matter (PM2,5) and explicitly regulates the subtraction of particulate matter originating from natural sources when establishing exceedances. Article20(1) of Directive2008/50/EC says that Member States shall provide the Commission with information on concentrations and sources and the evidence demonstrating that the exceedances are attributable to natural sources. Once the Commission has been notified accordingly, that exceedance will not be considered as an exceedance for the purposes of the directive. The way in which the Netherlands applies ‘sea salt subtraction’ does not seem to comply with this directive: the Netherlands currently fails to identify per exceedance day the percentage of sea salt in the measured particulate matter and whether the exceedance can be attributed to this concentration of sea salt.  1.Is it true that the Commission has notified Deputy Minister Atsma that the way in which the Netherlands applies the sea salt subtraction does not comply with the directive and that the Netherlands must amend its regulation for sea salt subtraction? I would like to have sight of this correspondence with the Netherlands; can the Commission make this correspondence public?  2.Has the Commission been informed whether and how the Netherlands will amend the sea salt subtraction?  3.Is the Commission satisfied with the new way in which the Netherlands will apply the sea salt subtraction?  4.Will the Commission urge the Netherlands to apply the new regulation for sea salt subtraction retroactively (i.e.for the year2011)?"
