An application for a certificate of occupancy for a building in any industrial zone must be accompanied by a description of industrial operations proposed in sufficient detail to indicate the maximum sound pressure level, dB(A) as shall be produced in all directions of the building and measured at lot lines.
The owner or his or its agent or person in possession requesting the certificate of occupancy shall further make available to the Building Inspector, if requested, the services of an expert who will certify the accuracy of the estimated sound pressure level, dB(A).
