Derogations from the provisions of articles L. 3134-3 and L. 3134-4 may be granted by the administrative authority for categories of activities whose full or partial operation is necessary on Sundays or public holidays in order to satisfy the needs of the population which are of a daily nature or which are particularly apparent on those days.
The same applies to businesses that operate exclusively or predominantly with engines powered by wind energy or irregular water power.
The rules governing these exemptions take account of the provisions of the eighth paragraph of article L. 3134-5. A decree may specify the terms and conditions of these exemptions.
