## Notice

The Coal Authority (CA) is a non-departmental public body and partner organisation of the Department for Energy Security and Net Zero (DESNZ) with a mission to make a better future for people and the environment in mining areas. The Coal Authority manages the effects of past coal mining, including subsidence damage claims which are not the responsibility of licensed coal mine operators. It deals with mine water pollution from both coal and metal mines and other mining legacy issues. The Coal Authority owns, on behalf of the country, the majority of the coal in Britain, and licenses coal mining. We use our skills to provide services to other government departments and agencies, local governments and commercial partners. We contribute to the delivery of the UK Government's Industrial Strategy and the environmental, social and economic priorities of the UK, Scottish and Welsh Governments. By sharing our knowledge and expertise we support them, and our partners, to create cleaner, greener nations for us all. We currently have the capacity to treat 220 billion litres of mine water every year. Treating mine water has directly protected and improved over 350km of rivers, protects several important regional aquifers, enhances biodiversity and provides local amenity land. By treating the mine water we have prevented nearly 4,000 tonnes per year of iron solids and other pollutants entering watercourses or aquifers. Last year 89% of the iron solid waste was recycled or reused. We are responsible for protecting the environment by addressing and mitigating the environmental impacts of coal mining, our Business Plan for 2022 to 2025 provides an overview of the Coal Authority and explains our main priorities for the period, along with the organisation's 10 year vision. Our work involves monitoring and remediating contaminated land and water resulting from historical mining activities.
