Cafodd y Rheoliadau Adnoddau Dŵr (Rheoli Llygredd Amaethyddol) eu cyflwyno ym mis Ebrill 2021 i fynd ati ar lefel Cymru gyfan i leihau’r risg o lygru dŵr gan weithgareddau amaethyddol. Mae’r Rheoliadau wedi bod yn cael eu rhoi ar waith dros gyfnod o bedair blynedd a daw’r set derfynol o fesurau, sy’n ymwneud â gofynion storio, i rym yn ddiweddarach eleni. Cafodd y cynllun Rheoli Maethynnau’n Well ei gyflwyno ar gyfer blwyddyn galendr 2024 i roi mwy o amser i fusnesau fferm gydymffurfio â’r gofynion.
The Water Resources (Control of Agricultural Pollution) Regulations were introduced in April 2021 and set out an all-Wales approach to mitigating the risks of water pollution from agricultural activities. Implementation has been spread over a four-year period and the final set of measures, relating to storage requirements, will come into force later this year. A 12-month Enhanced Nutrient Management Approach was introduced for the 2024 calendar year to give affected farm businesses more time to comply with the requirements.
