It is the purpose of these standards to assure that all lots, parcels, buildings or structures in all districts are used or occupied in a manner so as not to create any dangerous, injurious, noxious or otherwise objectionable elements or conditions so as to adversely affect adjacent properties or the surrounding area and/or public health. 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 accepted limits as established by the following performance requirements. If the operations of any lawful existing use at the date of adoption of this Chapter violates these environmental performance standards, such operations shall not be varied or changed in any way as to increase the degree of such violations.

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 measures and devices as are normally used in the handling of any such material. Such hazards shall be kept removed from adjacent activities to a distance compatible with the potential danger involved. The storage and use of any combustible or non-combustible material, or any material which presents an explosion hazard, shall be stored and handled in accordance with the Building Code and Fire Prevention Code of the City of Hazelwood, the standards and regulations of the National Fire Protection Association and the regulations of the fire protection district which has jurisdiction.

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

No vibration shall be permitted which is perceptible without instrument on any lot line of the lot on which the use is located, except blasting conducted in accordance with the requirements of the Explosive Code, Chapter 711, St. Louis County Revised Ordinance may exceed these limitations.

Every use shall be so operated that no smoke from any source shall be emitted that exceeds the emission levels in the requirements of the Air Pollution Code, Chapter 612 and St. Louis County Revised Ordinance.

Every use shall be so operated that no offensive or objectionable odor is emitted which is offensive so as to produce a public nuisance or hazard on any adjoining lot or property. Odors emitted from any operations shall comply with the requirements of the Air Pollution Code, Chapter 612, St. Louis County Revised Ordinance; all applicable standards of the State of Missouri Department of Natural Resources; and the U.S. Environmental Protection Agency.

No pollution of air by dirt, dust, fly-ash or other forms of particulate matter shall be permitted which is harmful to the health of humans, animals, vegetation or other property or which causes soiling of exposed property.

No direct or reflected glare shall be permitted which is visible from any property or from any public street, road or highway. Any operation producing intense glare or heat shall be performed in an enclosure in such a manner as to be imperceptible without instruments along any lot line of the lot upon which the building is constructed.

Noise which is objectionable due to volume, frequency or heat shall be muffled or otherwise controlled so that there is no production of sound discernible at lot lines in excess of the average intensity of street and traffic noise at the lot lines. Every use shall be so operated that the pressure level of sound or noise generated does not exceed the limitations of the Noise Control Code, Chapter 625, St. Louis County Revised Ordinance. Emergency warning sirens and related apparatus used solely for public purposes shall be exempt from this requirement.
