Annex I

Directive 2004/107/EC is amended as follows:

1. (1)

   Section I of Annex IV is amended as follows:

   1. (a)

      the table is replaced by the following:

      Distributed over the year to be representative of various conditions for climate and anthropogenic activities
      Indicative measurement being measurements which are performed at reduced regularity but fulfil the other data quality objectives’
      	‘Benzo(a)pyrene	Arsenic, cadmium and nickel	Polycyclic aromatic hydrocarbons other than benzo(a)pyrene, total gaseous mercury	Total deposition
      — Uncertainty
      Fixed and indicative measurements	50 %	40 %	50 %	70 %
      Modelling	60 %	60 %	60 %	60 %
      — Minimum data capture	90 %	90 %	90 %	90 %
      — Minimum time coverage
      Fixed measurementsf1	33 %	50 %
      Indicative measurements f2	14 %	14 %	14 %	33 %

   2. (b)

      in the third paragraph, the following sentence is deleted:

      ‘Twenty-four hour sampling is also advisable for the measurement of arsenic, cadmium and nickel concentrations.’

   3. (c)

      after the third paragraph the following text is inserted:

      ‘The provisions on individual samples in the previous paragraph apply also to arsenic, cadmium, nickel and total gaseous mercury. Moreover, sub–sampling of PM₁₀ filters for metals for subsequent analysis is allowed, providing there is evidence that the sub-sample is representative of the whole and that the detection sensitivity is not compromised when compared with the relevant data quality objectives. As an alternative to daily sampling, weekly sampling for metals in PM₁₀ is allowed provided that the collection characteristics are not compromised.’

2. (2)

   Sections I to IV of Annex V are replaced by the following:

   ‘I.

   Reference method for the sampling and analysis of arsenic, cadmium and nickel in ambient air

   The reference method for the sampling of arsenic, cadmium and nickel in ambient air is described in EN 12341:2014. The reference method for the measurement of arsenic, cadmium and nickel in ambient air is that described in EN 14902:2005 “Ambient air quality — Standard method for the measurement of Pb, Cd, As and Ni in the PM10 fraction of suspended particulate matter”.

   A Member State may also use any other methods which it can demonstrate give results equivalent to the above method.

   II.

   Reference method for the sampling and analysis of polycyclic aromatic hydrocarbons in ambient air

   The reference method for the sampling of polycyclic aromatic hydrocarbons in ambient air is described in EN 12341:2014. The reference method for the measurement of benzo(a)pyrene in ambient air is that described in EN 15549:2008 “Air quality — Standard method for the measurement of concentration of benzo[a]pyrene in ambient air”. In the absence of a CEN standard method for the other polycyclic aromatic hydrocarbons referred to in Article 4(8), Member States are allowed to use national standards methods or ISO methods such as ISO standard 12884.

   A Member State may also use any other method which it can demonstrate give results equivalent to the above method.

   III.

   Reference method for the sampling and analysis of mercury in ambient air

   The reference method for the measurement of total gaseous mercury concentrations in ambient air is that described in EN 15852:2010 “Ambient air quality — Standard method for the determination of total gaseous mercury”.

   A Member State may also use any other method which it can demonstrate give results equivalent to the above method.

   IV.

   Reference method for the sampling and analysis of the deposition of arsenic, cadmium, mercury, nickel and polycyclic aromatic hydrocarbons

   The reference method for the determination of the deposition of arsenic, cadmium, and nickel is that described in EN 15841:2009 “Ambient air quality — Standard method for determination of arsenic, cadmium, lead and nickel in atmospheric deposition”.

   The reference method for the determination of the deposition of mercury is that described in EN 15853:2010 “Ambient air quality — Standard method for determination of mercury deposition”.

   The reference method for the determination of the deposition of benzo(a)pyrene and the other polycyclic hydrocarbons referred to in Article 4(8) is that described in EN 15980:2011 “Air quality. Determination of the deposition of benz[a]anthracene, benzo[b]fluoranthene, benzo[j]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenz[a,h]anthracene and indeno[1,2,3-cd]pyrene”.’
