Naturally Occurring Radioactive Materials (NORM)
We are responsible for regulating the keeping and use of radioactive substances and the accumulation and disposal of radioactive wastes. These pages describe the development of the UK strategy for managing wastes containing naturally occurring radioactive material (NORM).

These pages describe the development of the UK strategy for managing wastes containing naturally occurring radioactive material (NORM).
Naturally occurring radioactive materials exist in the earth’s crust as a result of the decay of heavy elements produced by cosmic processes. In their natural state they are not considered waste. NORM waste is produced when activities including mining and the processing of minerals and contaminated earth concentrate NORM. It is also produced as a result of maintenance and decommissioning of equipm
Aquatic Classification
There are a number of significant environmental problems caused by a number of pressures, including diffuse and point source pollution, alterations to beds, banks and shores, alterations to water levels and flows and the presence of invasive non-native species. In order to measure these pressures and their potential effects, we use an aquatic classification system which covers rivers, lochs, estuaries, coastal and groundwater bodies. These are split into management units called water bodies, with a classification produced for each body (the number of water bodies between years varies slightly, as some water body boundaries are reviewed to ensure that they can be managed appropriately).

We produce an annual Water Framework Directive (WFD) Classification for all the water bodies in Scotland.
Classification results for 2007 to the current year can be found on the Water Classification Hub.

Most of our water environment is already in a good condition and subject to fewer pressures than most other E
Radioactive waste advisers
There is a requirement under European law for people who keep or use radioactive material, or who accumulate or dispose of radioactive waste, to appoint advisers, known as ‘radiation protection experts’ to advise them on radiological protection.

What are we able to do?
We can now accept:
Applications for an EASR18 authorisation (please contact sepa.org.uk/contact).
Online notifications EASR18 for orphan source or managed radioactive substances (only IAEA category 5 that: exceed 200 kBq; tritium sources exceeding 20 GBq; and electrodeposited source. Radioactive substances in IAEA ca
Modelling
Marine aquaculture modelling
Computer modelling is used as a guide to determining licensed discharge quantities of anti-parasitic chemicals and organic waste arising from marine fish-farm operations.
The modelling tools promoted by SEPA provide robust predictions in most cases, requiring relatively little site-specific information. Nevertheless, the quality of the model outputs is dependent upon g
Zero Waste
SEPA works with the Scottish Government and Zero Waste Scotland to achieve the objectives and targets of the Zero Waste Plan, published in 2010.
We have a wide range of responsibilities including regulating waste management activities such as landfills, incinerators and the export of waste, administering the producer responsibility schemes for packaging, WEEE and batteries, collecting and interpre
Technical guidance
Further technical guidance
This page brings together a number of ancillary guidance documents and previous email bulletin information relating to modelling of marine fish-farms for CAR licence applications.
Auxiliary biomass sampling transect
In areas where the tidal residual current is weak, the auxiliary transect (site-specific sampling 2) may be aligned along a bearing reciprocal to the primary
Frequently asked questions
To make this section of our website easier to use, we have broken down the questions most commonly asked of us into two sections: Section A gives an introduction to the regulations and how they are enforced and may be of use to smaller businesses and contractors. Section B goes into more detail and describes definitions, concepts and processes and is a useful resource for consultants, regulators and larger businesses and contractors. It also gives more information about how the regulations differ between Scotland and England.

Legislative framework
Part IIA of the Environmental Protection Act 1990 (EPA) (‘Part IIA’), which came into force in July 2000, provides the legislative framework for the identification and remediation of contaminated land. The legislation introduced a statutory definition of contaminated land and is aimed at addressing land which has been historically contaminated and which poses unacceptable risks to human health or the wider environment in the context of the current land use.
