(H) "Public receptor" means off-site residences, institutions such as schools or hospitals, industrial, commercial, and office buildings, parks, or recreational areas inhabited or occupied by the public at any time where the public could be exposed to toxic concentrations, radiant heat, or overpressure as a result of an accidental release.

Properties shall not be considered contiguous solely because of a railroad or pipeline right-of-way.
