- Y Diweddaraf sydd Ar Gael (Diwygiedig)
- Gwreiddiol (a wnaed Fel)
Dyma’r fersiwn wreiddiol (fel y’i gwnaed yn wreiddiol). Dim ond ar ei ffurf wreiddiol y mae’r eitem hon o ddeddfwriaeth ar gael ar hyn o bryd.
Regulation 7(4)
(a)Diffuse sources
Population of zone (thousands) | If concentrations exceed the upper assessment threshold | If maximum concentrations are between the upper and lower assessment thresholds | For SO2 and NO2 in agglomerations where maximum concentrations are below the lower assessment thresholds |
---|---|---|---|
0 –250 | 1 | 1 | not applicable |
250 –499 | 2 | 1 | 1 |
500 –749 | 2 | 1 | 1 |
750 –999 | 3 | 1 | 1 |
1,000 –1,499 | 4 | 2 | 1 |
1,500 –1,999 | 5 | 2 | 1 |
2,000 –2,749 | 6 | 3 | 2 |
2,750 –3,749 | 7 | 3 | 2 |
3,750 –4,749 | 8 | 4 | 2 |
4,750 –5,999 | 9 | 4 | 2 |
>6,000 | 10 | 5 | 3 |
For NO2 and particulate matter: to include at least one urban-background station and one traffic-orientated station |
(b)Point sources
For the assessment of pollution in the vicinity of point sources, the number of sampling points for fixed measurement should be calculated taking into account emission densities, the likely distribution patterns of ambient-air pollution and the potential exposure of the population.
If maximum concentrations exceed the upper assessment threshold | If maximum concentrations are between the upper and lower assessment thresholds |
---|---|
In island zones the number of sampling points for fixed measurement should be calculated taking into account the likely distribution patterns of ambient-air pollution and the potential exposure of ecosystems or vegetation. | |
1 station every 20,000 km2 | 1 station every 40,000 km2 |
Y Diweddaraf sydd Ar Gael (diwygiedig):Y fersiwn ddiweddaraf sydd ar gael o’r ddeddfwriaeth yn cynnwys newidiadau a wnaed gan ddeddfwriaeth ddilynol ac wedi eu gweithredu gan ein tîm golygyddol. Gellir gweld y newidiadau nad ydym wedi eu gweithredu i’r testun eto yn yr ardal ‘Newidiadau i Ddeddfwriaeth’.
Gwreiddiol (Fel y’i Deddfwyd neu y’i Gwnaed): Mae'r wreiddiol fersiwn y ddeddfwriaeth fel ag yr oedd pan gafodd ei deddfu neu eu gwneud. Ni wnaed unrhyw newidiadau i’r testun.
