The use of any discharge would require all relevant permissions, licences and permits supported by a thorough appraisal to determine whether the nature of the workings would support a scheme. Caveats The opportunity areas and discharge locations delineated on this map do not give any guarantee that any future permits, licences, access agreements or permissions will be granted. The priority rankings and discharge locations offer no guarantee of the success of a mine water heat scheme in any location. Any proposed mine water heat scheme will need to be subject to detailed feasibility studies and all relevant permits, permissions, licences and agreements from all relevant bodies. The mine water heat opportunity map is subject to change as mine water levels change, especially where they are recovering post mine closure. 51.54208186569814 -4.246894978182086 53.18476177441629 -3.001017271422322
