Our Sector Guidance Notes (SGNs) aim to provide operators and our regulatory officers with advice on indicative standards of operation and environmental performance, relevant to the industrial sector concerned.
In addition to your specific sector guidance, Technical Guidance Notes (TGNs) describe the standards and measures you must use to control the most common risks of pollution from your activity. They are vital to help you understand how to comply with the conditions or rules of your permit.
You will find documents available to download at the bottom of this page. There are also links out to the Environment Agency guidance on the .Gov.uk website and other supporting guidance, which Natural Resources Wales is continuing to follow.
There are also many industry guidance documents that may help you to understand standards, and put appropriate measures in place to control your activities and prevent pollution.
