Permits for such work may not be granted:a.  in groundwater protection zones;b.  below the groundwater table of groundwater resources whose amount and quality are suitable for water supply;c.  for watercourses where the bed load budget may be negatively affected.For groundwater resources whose amount and quality are suitable for water supply, extraction may be permitted above groundwater level, provided a protective layer of material is left above the maximum groundwater table possible. The dimension of this protective layer shall be chosen according to the local conditions.
