River Severn Drought Order Environmental Report (Working Draft) Version 7 - December 2013 UNCLASSIFIED UNCLASSIFIED - Working draft document We are the Environment Agency. We protect and improve the environment and make it a better place for people and wildlife in England. We operate at the place where environmental change has its greatest impact on people’s lives. We reduce the risks to people and properties from flooding; make sure there is enough water for people and wildlife; protect and improve air, land and water quality and apply the environmental standards within which industry can operate. Acting to reduce climate change and helping people and wildlife adapt to its consequences are at the heart of all that we do. We cannot do this alone. We work closely with a wide range of partners including government, business, local authorities, other agencies, civil society groups and the communities we serve.

UNCLASSIFIED- Working Draft document 2 of 183 UNCLASSIFIED - Working draft document Foreword This environmental report has been produced by the Environment Agency, in consultation with Natural Resources Wales and two of its predecessors (Environment Agency Wales and the Countryside Council for Wales). From 1 April 2013 Natural Resources Wales, which was formed by the Welsh Government, took over the functions previously carried out by Environment Agency Wales, Countryside Council for Wales and the Forestry Commission Wales. The relationship between Natural Resources Wales and the Environment Agency was set out in a Memorandum of Understanding, with the Environment Agency remaining the lead organisation for water resources planning activities in the River Severn catchment. However, the River Severn flows through England and Wales and the geographical area covered includes Powys, which is now the overall responsibility of Natural Resources Wales While site-based work is only generally undertaken by Environment Agency staff in England and by Natural Resources Wales staff in Wales, we plan together in relation to shared water bodies, water catchments, estuaries, and groundwater resources. The Environment Agency leads on water resources planning activities in the Severn catchment, which includes River Severn regulation and drought planning, while Natural Resources Wales lead in the Dee and Wye catchments which also flow through England and Wales. To produce this report the Environment Agency has also actively consulted with Natural England to ensure protected areas of land, designated sites and the wildlife habitats within these areas are considered appropriately. We also consulted the water companies, Severn Trent Water Ltd and South Staffordshire Water Ltd, to ensure we assessed the potential combined impacts of the water companies operating their drought orders on the River Severn whilst we operated the River Severn Drought Order. Version Control Version 1: 2008-2009 AMEC 2008 draft report reviewed, scope for improvements produced. Version 2: 2009-2011 Update project; water resource and water quality modelling, environmental impact assessments and complete report re-write. Version 3 : January 2012 Draft report refined for initial consultation in preparation for building drought event. Version 4: April 2013 Draft amended to address initial consultation feedback (from EA, EA Wales, CCW, NE, STWL & SSW) and organisational changes. Draft edited to reduce size and fill gaps. Version 5: May 2013 Draft reformatted to appropriate Environment Agency template. Maps inserted and further content reduction. Version 6: June 2013 Draft edited following APEM consultant’s quality review against Defra guidance. Version 7 - December 2013 Draft updated to address external consultation comments.

Communication with internal Specialists in hydrology, water quality, ecology, biodiversity, stakeholders fisheries, water resource licensing and environment planning formed the internal project group and wider network. This included staff from West area, Midlands region, South West region and Environment Agency Wales (South East and North region). Advisory support was received from National and legal teams. Organisational change on 1 April 2013, Welsh Government formed Natural Resources Wales. Communication with other external Natural England, Countryside Council for Wales (now part stakeholders of Natural Resources Wales), Severn Trent Water Ltd, South Staffordshire Water Ltd and the Canal and River Trust (formerly British Waterways). External consultation Draft report published for external consultation July 2013- August 2013. Consultation was open to the public and key organisations contacted directly to encourage involvement. Responses included National Farmers Unions, United Utilities, Dŵr Cymru Welsh Water, the Institute for Civil Engineers and the above external stakeholders.

Future update time table The River Severn Drought Order Environmental report will remain a live document, allowing for minor updates to be made as appropriate. However a set timetable for comprehensive reviews will also be set as the following; • RSDO Environmental Report and supporting documents (e.g. HRA and SGS ER) to undergo a full review/update every 3-3.5 years or following a drought event. Next programmed update: 2016/17 • RSDO environmental monitoring programme to be reviewed annually (spring time recommended). This will include a summary of the data collected and a review of the sites and methods being used. UNCLASSIFIED- Working Draft document 5 of 183 UNCLASSIFIED - Working draft document Executive summary Droughts are infrequent events in the UK but when they do occur their impact can be significant. The Environment Agency has responsibility for alleviating the effects of drought on people, businesses and the environment through sensible management of water resources in England. The River Severn is the UK’s longest river. The majority of its catchment sits in England but substantial parts of it also sit in Wales. Since April 2013 the Environment Agency and Natural Resources Wales (NRW) have had joint responsibility for drought planning in the River Severn catchment. We are committed to working together where there is an environmental need or benefit; for drought planning it has been agreed the Environment Agency will take the lead in the River Severn catchment. This environmental report has been written to support an application for a River Severn Drought Order. A drought order outlines the procedures we will use to better manage our water resources during prolonged or extreme spells of dry weather. Around six million people rely on the River Severn catchment for drinking water as well as a huge number of businesses, leisure clubs and wildlife. The Environment Agency and NRW ensure that the River Severn is able to support all of these uses without compromising the environment. We must decide how much water needs to be released to the river from both surface water and groundwater storage sources to balance the needs of the river against the demands of abstraction. This is called River Severn regulation, and involves legal responsibility under the Joint Clywedog Reservoir Act (1963). The robustness of the water supply in the River Severn is judged by water levels in Llyn Clywedog reservoir in Wales. Procedures from the River Severn Drought Order will only be enforced when critical water levels in the reservoir are reached. The River Severn Drought Order would allow us to reduce the quantity of water released from the reservoir and restrict abstractions from the River Severn. This would preserve the remaining water resources and allow support to continue for longer to protect people and the environment against extended droughts. Llyn Clywedog reservoir is the main surface water store used to support the River Severn. Without its support
