(a) Requirements. 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 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 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.
Octave Band (In Cycles Per Second) | Along Residence District Boundaries - Maximum Permitted Sound Levels (In Decibels) | Along All Business District “M-1" and “M-2" Boundaries - Maximum Permitted Sound Level (In Decibels) |
0 to 150 | 70 | 70 |
150 to 300 | 60 | 66 |
300 to 600 | 52 | 60 |

(6) Odors. No malodorous gas or matter shall be permitted which is offensive or produces a public nuisance or hazard on any adjoining lot or property.

(8) Glare. No direct or reflected glare shall be permitted which is visible from any property outside an "M" 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.

(b) Enforcement Provisions.
(1) Submission of statements. The Zoning Inspector or Board of Zoning Appeals, prior to the issuance of a zoning certificate, may require the submission of statements and plans indicating the manner in which dangerous and objectionable elements involved in processing and in equipment operations are to be eliminated or reduced to acceptable limits and tolerances.
(2) Measurement procedures. Methods and procedures for the determination of the existence of any dangerous and objectionable elements shall conform to applicable standard measurement procedures published by the American Standards Association, Inc., New York, N.Y., the Manufacturing Chemists' Association, Inc.
