MTAN 2 was produced by the National Assembly for Wales in January 2009 to provide detailed advice on the policy for both surface and underground working of coal in Wales.
Annex 2 identifies the significant effects of noise from surface minerals operations, identifies good practice in controlling noise, and states how the planning system can keep noise emissions within environmentally acceptable limits without imposing unreasonable burdens on mineral operators.
Advice is provided on dealing with potential noise issues through the development control process. Recommendations are provided for acceptable noise levels, both for normal site operations, and for short term operations. Guidance is also given on compliance monitoring of noise limits and specific examples of good practice in noise reduction are detailed.
