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. Information Warning Some grid references within the data set are incorrect and are plotted outside Wales – these are in the process of being corrected.
