  • All

The Environmental Permitting Regulations contains exemptions from needing an environmental permit for certain water discharges and groundwater activities. Exemptions cover the discharge of treated domestic sewage to either surface or groundwater, managing vegetation near/on inland water, substances to ground for scientific purposes and discharges from open loop heating and cooling systems.


These exemptions must be registered with Natural Resources Wales. The Water Quality Exemptions dataset contains the locations for these registered exemptions in Wales.

Mae'r Rheoliadau Trwyddedu Amgylcheddol yn cynnwys esemptiadau rhag bod angen trwydded amgylcheddol ar gyfer rhai gollyngiadau dŵr a gweithgareddau dŵr daear. Mae esemptiadau yn cynnwys gollwng carthion domestig wedi’u trin naill ai i ddŵr wyneb neu ddŵr daear, rheoli llystyfiant ger/ar ddŵr mewndirol, sylweddau i’r ddaear at ddibenion gwyddonol a gollyngiadau o systemau gwresogi ac oeri dolen agored.


Rhaid i'r esemptiadau hyn fod wedi'u cofrestru â Cyfoeth Naturiol Cymru. Mae'r set ddata Eithriadau Ansawdd Dŵr yn cynnwys lleoliadau'r esemptiadau cofrestredig hyn yng Nghymru.
