(a) In M2 general manufacturing districts and M3 heavy manufacturing districts, any property use creating intense earthshaking vibrations shall be set back at least 300 feet from the boundary of a residence, business or commercial district and at least 150 feet from the boundary of an M1 restricted manufacturing district; provided that, there shall be no violation if the property use does not transmit beyond the lot lines any earthshaking vibrations which are perceptible without the aid of instruments.
(b) In all other districts, any property use creating earthshaking vibrations must be controlled in such manner as to prevent transmission beyond the lot line of earthshaking vibrations perceptible without the aid of instruments; provided that, this limitation does not apply where the affected adjoining property is zoned M3 (heavy manufacturing).
(c) In all zoning districts earthshaking vibrations that create a nuisance or hazard beyond the lot lines of the source are prohibited.
