No use of an extractive nature shall be maintained to a greater dimension than is depicted or upon land upon which such a use is not depicted upon an instrument survey or other acceptable map submitted and approved in support of an application for a certificate of occupancy.

No use of an extractive nature shall be maintained at a distance of less than 300 feet from a public highway or from any neighboring property.

All excavations shall be fenced in a manner sufficient to protect against trespass and to prevent injury to person and property.

Any building or structure containing explosive materials or substances shall be visibly marked as so containing and shall be completely fenced and locked at all times in such a manner as to protect against trespass and to prevent injury to person and property.
