PART 1 Group A pollutants
1 The following information shall be compiled for zones within which sources other than fixed measurement are employed to supplement information from fixed measurement or as the sole means of air quality assessment—
(a) a description of assessment activities carried out;
(b) the specific methods used, with references to descriptions of the method;
(c) the sources of data and information;
(d) a description of results, including information relating to—
(i) uncertainties;
(ii) in particular, the extent of any area or, if relevant, the length of road within the zone over which concentrations exceed the limit value or, as may be, the limit value plus applicable margin of tolerance; and
(iii) any area within which concentrations exceed the upper assessment threshold or the lower assessment threshold; and
(e) for limit values the object of which is the protection of human health, the population potentially exposed to concentrations in excess of the limit value.
2 Where possible maps shall be compiled showing concentration distributions within each zone.
