1. The representative concentration of the relevant pollutant shall be determined on the basis of concentrations during the previous five years where sufficient data are available. The upper assessment threshold will be deemed to have been exceeded if it has been exceeded during at least three separate years out of the previous five years. The lower assessment threshold will be deemed to have been equalled or exceeded if it has been equalled or exceeded during at least three separate years out of the previous five years.
2. Where fewer than five years' data are available, measurement campaigns of short duration during the period of the year and at locations likely to be typical of the highest concentrations may be combined with results obtained from emission inventories and modelling to determine exceedances of the upper and lower assessment thresholds.
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.
Mae Nodyn Gweithredol yn nodi datganiad byr o ddiben Offeryn Statudol yr Alban ac yn rhoi gwybodaeth am ei amcan polisi a goblygiadau polisi. Ei nod yw gwneud yr Offeryn Statudol yr Alban yn hygyrch i ddarllenwyr nad oes ganddynt gymhwyster cyfreithiol ac maent yn cyd-fynd ag unrhyw Offeryn Statudol yr Alban neu Offeryn Statudol Drafft yr Alban a gyflwynwyd yn fanwl gerbron Senedd yr Alban o Orffennaf 2005 ymlaen.
