Ownership. Whenever a lot is sold to a new owner, a previously lawful nonconforming use may be continued by the new owner, provided that there is no enlargement or change in the nonconformity.
E. 
Abandonment. If a nonconforming use of a building or land is abandoned for 12 consecutive months, whereby the owner discontinues the use with the intention neither of transferring rights of the property to another owner nor of resuming the use of the property, the subsequent use of such building or land shall conform to the regulations of the district in which it is located, unless another nonconforming use is approved by the Township Council in accordance with Subsection F and that such approved use be initiated within 30 days after the end of the twelve-month period.
F. 
Changes. Once changed to a conforming use, no structure or land shall be permitted to revert to a nonconforming use.

A. 
No building may be erected, altered or used and no lot or premises may be used for any trade, industry, business or other activity that is noxious or offensive by reason of odor, dust, smoke, gas, vibration, illumination, noise, toxic chemicals or other disturbance which constitutes a public hazard, whether by fire, explosion or otherwise. In determining whether a proposed use is or may become noxious, hazardous or offensive, each such use shall comply with the performance standards below; and no internal combustion engine shall be used unless objectionable noise and vibration are eliminated and proper disposition is made of exhaust gases.
