THE COMMISSION OF THE EUROPEAN COMMUNITIES, 

Having regard to the Treaty establishing the European Community, 

Having  regard  to  Council  Directive  96/62/EC  of  27  September  1996  on  ambient  air  quality 
assessment and management42, and in particular Article 12(1) thereof,

Directive  96/62/EC  establishes  the  framework  for  assessment  and  management  of 
ambient air quality and provides that detailed arrangements are to be laid down for 
the reporting of information on air quality. 

Council Directive 1999/30/EC of 22 April 1999 relating to limit values for sulphur 
dioxide,  nitrogen  dioxide  and  oxides  of  nitrogen,  particulate  matter  and  lead  in 
ambient air43 lays down limit values to be met on a certain target date. 

Commission  Decision  2001/839/EC  laying  down  a  questionnaire  to  be  used  for 
annual  reporting  on  ambient  air  quality  assessment  under  Directives  96/62/EC  and 
1999/30/EC44  provided  a  model  on  the  basis  of  which  Member  States  were  to 
provide the information on air quality required under those Directives. 

Directive  2000/69/EC  of  the  European  Parliament  and  of  the  Council  of  16  April 
2000 relating to limit values for benzene and carbon monoxide in ambient air45 lays 
down  limit  values  to  be  met  on  a  certain  target  date.  Directive  2002/3/EC  of  the 
European  Parliament  and  of  the  Council  of  12  February  2002  relating  to  ozone  in 
ambient  air46  lays  down  target  values,  long-term  objectives,  information  and  alert 

OJ  L  296,  21.11.1996,  p.  55.  Directive  as  amended  by  Regulation  (EC)  No  1882/2003  (OJ  L  284, 
31.10.2003, p.1). 
OJ L 163, 29.6.1999, p.41. Directive as amended by Decision 2001/744/EC (OJ L 278, 23.10.2001, p.

thresholds  which  create  certain  obligations.  Regular  reporting  by  Member  States  is 
an integral element of those Directives, read in conjunction with Directive 96/62/EC 
and indispensable for checking compliance with those obligations.

Moreover, a number of items set out in Article 11 of Directive 96/62/EC with regard 
to  the  pollutants  covered  by  Directives  1999/30/EC,  2002/69/EC  and  2002/3/EC 
must be reported on an annual basis. 

According to Directive 1999/30/EC, provisions on reporting under Council Directive 
80/779/EEC  on  air  quality  limit  values  and  guide  values  for  sulphur  dioxide  and 
suspended  particulates47,Council  Directive  82/884/EEC  of  3  December  1982  on  a 
limit value for lead in the air48 and Council Directive 85/203/EEC of 7 March 1982 
on air quality standards for nitrogen dioxide49 are repealed with effect from 19 July 
2001, although the limit values under these Directives remain in force until 2005 for 
Directives  80/779/EEC  and  82/884/EEC,  and  2010  for  Directive  85/203/EEC  and 
reporting on exceedences of these limit values continues according to Article 9(6) of 
Directive 1999/30/EC. 

In  order  to  ensure  that  the  required  information  is  supplied  in  the  correct  format, 
Member  States  should  be  required  to  submit  it  on  the  basis  of  a  standardised 
questionnaire. 

The questionnaire laid down by Decision 2001/839/EC should be extended to cover 
also  the  annual  reporting  obligations  resulting  from  Directives  2000/69/EC  and 
2002/3/EC,  while  at  the  same  time  introducing  some  amendments  related  to 
Directive  1999/30/EC,  which  are  made  for  clarification  and  in  order  to  ensure  a 
better assessment of the reports. 

(9) 

Decision 2001/839/EC should be replaced in the interests of clarity. 

(10)

The Member State should give not only the zone name, but also a unique zone code.  

The Member State should indicate the pollutant(s) to which the zone applies using the 
codes: ‘S’ for SO2, ‘N’ for NO2/NOx, ‘P’ for PM10, ‘L’ for lead, ‘B’ for benzene, ‘C’ 
for carbon monoxide and ‘O’ for ozone, separated by a semicolon, or ‘A’ if the zone 
applies  to  all  these  pollutants.  If  zones  have  been  separately  defined  for  health, 
ecosystem  and  vegetation  protection,  the  Member  State  should  use  the  following

It should be indicated whether the zone is an agglomeration (code: ‘ag’) or not (code: 
‘nonag’). 

Optionally, the Member States may add the  area and population size of the zone for 
further processing of the data at European level. 

For further processing, the Member State is requested to fill in the zone borders in a 
standard format (polygons, using the geographical coordinates according to ISO 6709: 
geographical  longitude  and  latitude).  The  Member  State  is  requested  to  provide 
separately a map of the zones (as an electronic file or on paper) to facilitate the correct 
interpretation of the zone data. The Member State must provide at least either the zone 
borders in Form 2 or a map.

In Form 3 and other forms in this questionnaire, ‘EoI station code’ refers to the code 
that  is  used  for  the  exchange  of  data  under  the  Exchange  of  Information  Decision 
97/101/EC. ‘Local station code’ is the code used within the Member State or region. 

The Member State is requested to identify in the third column the zone(s) applying to 
ozone in  which the station is  located.  If  more  than  one  zone  is  concerned,  the  codes 
should be separated by a semicolon. 

The  Member  State  is  requested  to  use  the  columns  headed  by  ‘SO2’,  ‘NO2’,  ‘NOx’, 
‘Lead’,  ‘Benzene’  and  ‘CO’  for  indicating  whether  the  measurement  is  used  for 
assessment under Directive 1999/30/EC or 2000/69/EC respectively, ticking with ‘y’ 
if  used  and  leaving  the  cell  empty  if  not  used.  It  should  be  noted  that  ticking  NOx 
implies  that  the  station  is  sited  at  a  location  where  the  limit  value  for  vegetation 
applies. If the station is in the immediate vicinity of specific sources of lead as referred 
to in Annex IV to Directive 1999/30/EC, the Member State is requested to tick with 
‘SS’ instead of ‘y’. 

(4) 

The  Member  State  should  use  the  columns  headed  by  ‘PM10’  and  ‘PM2,5’  for 
indicating  whether  the  measurement  is  used  for  assessment  under  Directive

1999/30/EC and indicate at the same time which measurement method is used. If the 
measurement is used for assessment under the Directive, the Member State should fill 
in  the  measuring  method  code  (see  Note  5);  if  the  measurement  is  not  used  for 
assessment under the Directive, the cell should be left empty. For PM2,5 levels formal 
assessment under Article 6 of Directive 96/62/EC is not required. 

(5) 

The  measurement  method  code  for  PM10  and  PM2,5  can  be  indicated  by  one  of  the 
standard codes provided by this questionnaire (see Table 1) or a code defined by the 
Member State that refers to a separate list of methods described by the Member State 
(see Form 7). The description defined by the Member State may also be a reference to 
a separate document added to the questionnaire. If the measurement method has been 
changed during the year, the Member State is requested to fill in both method codes: 
first the method that was used for the longest time in the year, followed by the other 
one, separated by a semicolon. 

(6)  When  the  measurement  method  for  PM10  or  PM2,5  is  not  the  reference  method, 
respectively the provisional reference method, set out in Directive 1999/30/EC, Annex 
IX,  the  Member  State  is  requested  to  fill  in  the  correction  factor  by  which  the 
measured concentrations have been multiplied to obtain the concentrations reported in 
this  questionnaire  or  to  fill  in  the  corresponding  correction  equation.  If  a  correction 
equation  has  been  applied,  a  free  format  can  be  used  in  which  the  measured 
concentration  should  be  denoted  by  ‘CM’  and  the  reported  concentration  by  ‘CR’, 
preferably  using  the  format  CR  =  f(CM).  If  the  results  of  the  method  have  been 
demonstrated  to  be  equivalent  without  the  application  of  a  correction,  the  Member 
State is requested to indicate this by entering the value ‘1’ for the correction factor or 
equation. 

(7) 

‘Function of station’ indicates whether the station is sited at a location where (a) the 
limit values for health, the SO2 limit value for ecosystems and the NOx limit value for 
vegetation apply (code ‘HEV’), (b) only the limit values for health and the SO2 limit 
value  for  ecosystems  apply  (code  ‘HE’),  (c)  only  the  limit  value  for  health  and  the 
NOx  limit  value  for  vegetation  apply  (code  ‘HV’)  or  (d)  only  the  limit  values  for 
health apply (code ‘H’).

Notes to Form 8: 

(1) 

The column headings have the following meaning: 

>LV + MOT: 

above the limit value plus the margin of tolerance; 

≤LV + MOT; >LV: 

below  or  equal  to  the  limit  value  plus  the  margin  of  tolerance  but 
above the limit value; 

≤LV: 

>LV: 

SS: 

below or equal to the limit value; 

above the limit value; 

due to specific sources, see Note 7. 

Art 3(2) 

extension period granted, see Note 8. 

(2) 

(3) 

(4) 

(5) 

(6) 

(7) 

‘>LV + MOT’ should be read as ‘>LV’ when the margin of tolerance has decreased to 0 %. In that case the column headed by ‘≤LV + MOT; 
>LV’ should not be used. 

If the column heading describes the status of the zone, tick with ‘y’. 

If exceedence has been concluded from model calculations solely, tick with ‘m’ instead of ‘y’. 

For thresholds for ecosystems and vegetation, tick only when exceedence occurred in areas where these limit values apply. For zones in which 
no areas exist where these limit values apply, tick column ‘≤LV’ by ‘n’. 

The winter mean is defined as the period from 1 October of the year preceding the reference year to 31 March of the reference year.  

If the exceedence status indicated in Form 8d is solely due to exceedence in an area in the immediate vicinity of specific sources designated 
according to Annex IV to Directive 1999/30/EC, the Member State is requested to indicate this by ticking column ‘SS’ by ‘y’.

(8) 

In  Form  8e,  ‘LV’  refers  to  the  limit  value  specified  in  Directive  2000/69/EC  Annex  I.  For  zones  for  which  the  Commission  has  granted  an 
extension  period  for  benzene  according  to  Article  3(2)  to  Directive  2000/69/EC,  the  Member  State  is  requested  to  indicate  this  by  ticking 
column ‘Art3(2)’ by ‘y’.

Identifying the station by filling in the EoI station code is not mandatory, but highly recommended. 

The phrase ‘limit value plus MOT’ should be read as ‘limit value’ when the margin of tolerance has decreased to 0%. 

‘Month’ and ‘Day of month’ should be indicated by its number (1-12 and 1-31 respectively). ‘Hour’ should be indicated as ‘1’ for the hour 
between 00:00h and 01:00h etc. 

All exceedences of the limit value plus the margin of tolerance at a station are reported if the total number of exceedences is above the allowed 
number. If the total number of exceedences at a station is lower than or equal to the allowed number, no exceedences are reported.  

The reason of exceedence can be indicated by one or several standard codes provided by this questionnaire (see Table 2) or a code defined by 
the Member State that refers to a separate list of reasons described by the Member State (Form 12). If more than one reason is indicated, the 
codes should be separated by a semicolon. The description given by the Member State could also be a reference to a separate document added 
to the questionnaire. 

For exceedences in zones for which the Commission has, according to Directive 2000/69/EC Article 3(2), granted a time-limited extension, the 
Member State is requested to enter ‘y’ in the column headed by ‘Article 3(2)’. 

If no exceedences above the number of allowed exceedences have been observed, the Member State is requested to enter ‘No exceedences’ in 
the left cell of the first row.

13a and 13b: An exceedence period is a continuous period on a single calendar day during which a threshold was continuously exceeded. A 
period cannot include hours of more than a single calendar day. If more than one exceedence period occurs on a calendar day, each period 
must be reported separately.

The data should be consistent with the requirements in Directive 2002/3/EC, Annex I(II), Footnotes b and c. If the three or five year averages 
could not be determined on the basis of a full and consecutive set of annual data, each year taken into account in the calculation should be 
indicated in the rightmost column, separated by a semicolon from other years.  

Form 14a: All exceedences of the target value at a station are reported if the total number of exceedences is above the allowed number. If the 
total number of exceedences at a station is lower than or equal to the allowed number, no exceedences are reported.

In  the  first  line  of  Form  16a  the  Member  State  should  report  the  EoI  station  codes 
and  in  the  following  lines  the  annual  average  concentration  of  ozone  precursor 
substances assessed under Directive 2002/3/EC Article 9(3). 

For ozone precursor substances other than those described in Form 16a and assessed 
under  Directive  2002/3/EC  Article  9(3),  the  Member  State  should  fill  in  Form  16b 
following  the  structure  of  Form  16a,  indicating  these  other  substances  in  the  first 
column. 

Whereas  reporting  obligations  of  ozone  precursor  substances  must 
include 
“appropriate  volatile  organic  compounds”,  the  list  presented  in  Form  16a  is  only  a 
recommendation according to Annex VI of Directive 2002/3/EC. 

Concentrations that have been reported under the Exchange of Information Decision 
97/101/EC should not be reported in Form 16.

Form 19 can be complemented by maps showing concentration distributions. It is recommended that the Member State, if possible, compiles 
maps  showing  concentration  distributions  within  each  zone  and  agglomeration.  It  is  recommended  to  provide  concentration  iso-lines  of  the 
parameters in which the air quality thresholds are expressed (see Table 3) using iso-lines at intervals of 10% of the threshold. 

The information should refer to the appropriate averaging period for the long term objectives (1 year), the target value for health (3 years) and 
the target value for vegetation (5 years).

The numerical value of the limit value exceeded should be indicated in the second column. 

For SO2 and  suspended particulates it  should  be indicated whether the black-smoke or the 
gravimetric method was used. 

Identifying the station is not mandatory, but highly recommended. 

The  reason  for  exceedence  can  be  indicated  by  one  or  several  standard  codes  provided  by 
this  questionnaire  (see  Table  5)  or  a  code  defined  by  the  Member  State  that  refers  to  a 
separate list of reasons described by the Member State (Form 27). If more than one reason is 
indicated,  the  codes  should  be  separated  by  a  semicolon.  The  description  given  by  the 
Member State could also be a reference to a separate document added to the questionnaire.
