(a) No operation or activity shall transmit any physical vibration that is above the vibration perception threshold of an individual at or beyond the property line of the source. Vibration perception threshold means the minimum ground- or structure-borne vibrational motion necessary to cause a normal person to be aware of the vibration by such direct means as, but not limited to, sensation by touch or visual observation of moving objects.
(b) Vibrations not directly under the control of the property user and vibrations from temporary construction or maintenance activities shall be exempt from the above standard.
