Cyfyngiadau ffosfforws ar drwyddedau amgylcheddol ar gyfer rhyddhau gwaith trin dŵr gwastraff
Rydym yn adolygu terfynau ffosfforws ar Drwyddedau Amgylcheddol ar gyfer gollyngiadau gwaith trin dŵr gwastraff sy'n fwy na llif tywydd sych o 20m3 / dydd.
Mae'r rhestr isod yn cynnwys yr holl drwyddedau yr ydym yn bwriadu eu hadolygu cyn mis Gorffennaf 2024.
Bydd y tabl yn cael ei ddiweddaru bob dydd Gwener wrth i fwy o drwyddedau gael eu rhyddhau.
Mae cyfnod apelio o ddau fis o'r dyddiad cyhoeddi. Os bydd cwmni dŵr yn apelio, byddwn yn diweddaru'r rhestr isod i nodi pa drwyddedau sy'n cael eu heffeithio. Bydd y drwydded ar gyfer y WwTW apeliedig yn dychwelyd i'r fersiwn flaenorol hyd nes y penderfynir ar ganlyniad yr apêl.
Gweler ein cofrestr gyhoeddus ar gyfer y Drwydded Amgylcheddol lawn ar ôl ei chyhoeddi.
Nid oes angen amrywiad neu derfynau ffosfforws ar sawl Gwaith Trin Dŵr Gwastraff mwyach oherwydd eu bod yn gollwng llai nag 20m3/dydd o elifiant carthion wedi'i drin. Dangosir y trwyddedau hyn fel 0mg/l (terfyn P) yn y tabl isod.
Mae trwyddedau presennol ar gyfer y safleoedd hyn yn dal i fod ar gael trwy ein cofrestr gyhoeddus.
