Context: Mae Rhan IV o Ddeddf yr Amgylchedd 1995 yn darparu'r fframwaith ar gyfer Rheoli Ansawdd Aer Lleol (LAQM). Mae'r gyfundrefn LAQM yn ei gwneud hi’n ofynnol i Awdurdodau Lleol weithio gydag eraill i asesu a rheoli risgiau i iechyd y cyhoedd o ganlyniad i lygredd aer. Gan ddefnyddio canllawiau statudol a thechnegol, rhaid iddynt gynnal adolygiadau ac asesiadau rheolaidd o ansawdd aer yn eu hardal yn erbyn yr amcanion ansawdd aer a chyflwyno Adroddiadau Cynnydd Blynyddol (APRs) i Lywodraeth Cymru. Os nad yw’r amcanion ansawdd aer yn debygol o gael eu cyflawni, rhaid i Awdurdodau Lleol ddynodi Ardaloedd Rheoli Ansawdd Aer (AQMAs) a rhoi Cynlluniau Gweithredu Ansawdd Aer (AQAPs) ar waith i ostwng lefelau llygredd.
