Tynagh Mines are on private lands, and the current owners have primary responsibility for management at the site. Any planned works that would be due to take place at the site and enforcement of the environmental legislation as it applies to the owners of the site, is a matter for Galway County Council.
I am aware that the Environmental Protection Agency (EPA) produced a report on the site in 2003 which stated that Galway Council is responsible for enforcing environmental legislation within its functional area, and the EPA has responsibility for enforcing compliance with the conditions of Integrated Pollution Control (IPC) Licences for current activities on the site. The current activities do not include mining.
