No parcel, lot, building or structure 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 Chapter 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. Environmental compatibility shall be of primary concern. No dust, mud, gravel or debris shall be permitted from driveways, parking areas or construction entrances that create a nuisance or hazard.

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.

No activity shall emit dangerous radioactivity at any point or unreasonable electrical or radioelectrical disturbance adversely affecting the operation at any point of any equipment other than that of the creator of such disturbance.

No vibration shall be permitted which is discernible without instruments on any adjoining lot or property.

Smoke shall not be emitted with a density greater than No. 1 on the Ringlemann Chart as issued by the U.S. Bureau of Mines except for blow-off periods of ten (10) minutes duration of one (1) per hour when a density of not more than No. 2 is permitted.

No malodorous gas or matter shall be permitted which is offensive so as to produce a public nuisance or hazard on any adjoining lot or property.

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, or which causes soiling of exposed property. In addition, all State and Federal requirements shall be addressed.

No direct or reflected glare shall be permitted which is visible from any property or from any public street, road or highway.

Noise which is objectionable due to volume, frequency or beat shall be muffled or otherwise controlled so that there is no productions of sound discernible at lot lines in excess of the average intensity of street and traffic noise at the lot lines. Air raid sirens and related apparatus used solely for public purposes are exempt from this requirement. The L-10 noise level (that level which is exceeded ten percent (10%) of the time) shall not exceed the following measurements at any point past the property line of the lot on which the noise is generated.

Pollution of streams and other bodies of water shall be subject to such requirements and regulations established by the State of Missouri, Department of Natural Resources (Water Quality Standard 10 CSR 20-7.031) and the City of New Melle, Missouri.
