Any use established or changed, and any building or land developed, constructed or used in a Limited Industrial and General Industrial District after the effective date of this Zoning Code (Ord. 1962-66, passed November 26, 1962), shall comply with the performance standards set forth hereinafter for the district in which such use or building is to be located as a precedence to occupancy and use. If any existing use or building is extended, enlarged or reconstructed, the performance standards for the district involved shall apply to such extended, enlarged or reconstructed part or parts of such building or use as a precedence to further use.
(a) Dust and Smoke. Dust and other types of air pollution borne by the wind from sources such as parking areas, storage areas or yards shall be kept to a minimum by appropriate landscaping, paving, oiling and other acceptable treatment.
The emission of smoke, soot, fly ash, fumes and dust shall be controlled by precipitation devices, height of stack, rate of emission or other manner so that the quantity deposited at any Residential or Business District shall not be detrimental to or endanger the public safety, comfort, welfare or adversely affect property values.
(b) Fire and Explosive Hazards.
(1) The storage, utilization and manufacture of materials, goods or products ranging from free to active burning is permitted, provided the materials or products shall be stored, utilized or produced within completely enclosed structures having incombustible exterior walls, and such structure shall be protected throughout by an automatic sprinkler system complying with installation standards prescribed by the National Fire Protection Association.
(2) Materials that produce flammable or explosive vapors or gases under ordinary weather temperatures shall not be permitted in Limited Industrial or General Industrial Districts except such materials as are used or required in emergency equipment or in secondary processes accessory to the main use.
(c) Glare and Heat. Any operation which produces glare or heat contrary to the normal and expected conditions shall be performed within an enclosure in such manner as to not be visible outside the building.
(d) Odorous Matter. The emission of odorous matter in such quantities as to produce a public nuisance or hazard shall not be detectable beyond the lot line in an L-I District and beyond the district boundary line in a G-I District.
(e) Toxic or Noxious Matter. The discharge of toxic or noxious matter across the lot lines wherein such a use is located is prohibited for any period of time and in such concentrations as to be detrimental to or endanger the public health, safety, comfort or welfare or cause injury or damage to property.
(f) Noise. The sound pressure level of any individual operation or operations on a lot in any Industrial District, other than the operation of auto-calls, bells, motor vehicles, sirens or whistles, shall not exceed the average intensity of the street traffic noise at the nearest Residential or Business District.
(g) Vibration. Operations creating intense earth-shaking vibrations shall be set back from and controlled in such a manner as to prevent transmission of vibrations which would be perceptible without the aid of instruments at the lot line in an L-I District or along the district boundary of a G-I District.
(h) Waste Materials. Liquid wastes shall not be discharged into an open reservoir, stream or other open public body of water or a sewer unless treated or controlled so that the amount of solid substances, oils, grease, acids, alkalises and other chemicals shall not exceed the amount permitted by other codes of the State, County or City.
(i) Enforcement. Where determinations can be made by the Building and Zoning Inspector or other authorized City employee, using equipment normally available or obtainable without extraordinary expense, such determinations or evaluation shall be made whenever possible before a notice of violation is issued. Where technical complexity or extraordinary personnel or equipment is required to make the determination, the Planning Commission may, in the case of the offenses under this section, require the owner to either obtain and pay for an independent survey or share in the cost of an independent survey from a professional engineer experienced in the particular specialty.
