(a) Requirement Limits. No land or building in any district shall be used or occupied in any manner so as to create any dangerous, injurious, noxious or otherwise objectionable element or condition so as to adversely affect the surrounding area or adjoining premises provided that any use permitted by this Zoning Ordinance may be undertaken and maintained if acceptable measures and safeguards are employed to limit dangerous and objectionable elements to acceptable limits as established by the following performance requirements:
(1) Fire hazards. Any activity involving the use or storage of chemicals, or flammable or explosive materials shall be protected by adequate fire- fighting and fire suppression equipment and by such safety devices as are normally used in the handling of any such material. Such hazards shall be kept removed from adjacent activities to a distance which is compatible with the potential danger involved.
(2) Radioactivity or electrical disturbance. No activity shall emit dangerous radioactivity at any point, or electrical disturbance adversely affecting the operation at any point of any equipment other than that of the creator of such disturbance.
(3) Noise. Noise which is objectionable as determined by the Board of Zoning Appeals due to volume, frequency or beat shall be muffled or otherwise controlled. Air-raid sirens and related apparatus used solely for public purposes are exempt from this requirement. The following table shall be used to determine the maximum noise level permitted:
Octave Band in Cycles Per Second | Along Residence District Boundaries - Maximum Permitted Sound Level in Decibels | Along All Commercial and Industrial District Boundaries - Maximum Permitted Sound Level in Decibels |
0 to 150 | 70 | 70 |
150 to 300 | 60 | 66 |
300 to 600 | 52 | 60 |
600 to 1200 | 46 | 53 |

(6) Odors. No odors shall be permitted which are offensive or which produce a public nuisance or hazard.
(7) Air pollution. No pollution of air by fly-ash, dust, vapors or other substances shall be permitted which is harmful to health, animals, vegetation or other property, which can cause excessive soiling, or is in violation of any State or federal laws or regulations.
(8) Glare. No direct or reflected glare shall be permitted which is visible from any property outside an "I" District or from any public street, road or highway.
(9) Erosion. No erosion, by either wind or water, shall be permitted which will carry objectionable substances onto neighboring properties.

(1) Proof of compliance. In any prior review required by the Municipal Planning Commission, the Commission may request environmental impact studies, and may request and receive reports and studies from local and state agencies and departments having jurisdiction over the property indicating whether any issues relating to or involving hazardous substances or environmental laws exist which would negatively impact the areas surrounding the property under consideration.
