Diffuse pollution in the urban environment (SUDS)

Sustainable urban drainage systems SUDS, or sustainable urban* drainage systems are a sequence of water management practices and facilities designed to drain surface water in a manner that will provide a more sustainable approach than what has been the conventional practice of routing run-off through a pipe to a watercourse. * The use of the word 'urban' is frequently omitted, but the meaning is s

Improving urban waters

Our vision is for towns and cities to use nature-based, blue-green solutions to absorb and safely convey rainwater. This will: help strengthen their resilience to the intense downpours they face under climate change minimise the risk of polluting sewage spills by keeping rainwater out of sewers create fantastic places for people to live and work Urban wastewaters Over the past 20 years, SEPA has

Technical concepts

Part IIA introduces a number of technical concepts and some key concepts are considered in this section. A number of methods and models are available to assist in the derivation of site specific assessment criteria, as highlighted in the other "technical concepts and tools" sections

Sea lice regulatory framework implementation

Frequently asked questions Why is a sea lice framework needed? Populations of wild Atlantic salmon have been in serious decline in recent decades and are now at crisis point. The pattern of decline is repeated across the salmon’s North Atlantic range and is likely caused, at least in part, by the effect of climate change on the survival of salmon during their time at sea. To build resilience of Sc

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

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.

Medium combustion plant

The medium combustion plant requirements of the PPC regulations are designed to control emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and dust into the air from plants with a net rated thermal input of between 1 and 50 megawatts (MW), contributing to better air quality and reducing the potential risks to human health and the environment. If you operate your own boiler, engine or genera
