SEC. 16-168.  PERFORMANCE STANDARDS; SPECIFIC.
 
Performance Standards
Industrial Zones: CM, BRP, M-L, M-1, and M-2
Noise
Baffling or muffling devices or other precautionary means shall be employed with processes or operations causing objectionable noise characteristics to prevent their being objectionable when measured at the property line during normal operation. Noise levels are required to comply with Chapter 7 of this code.
Smoke and particulates
Visible emissions of smoke shall not exceed Ringlemann No. 1 on the Ringlemann Chart of the U.S. Bureau of Mines, except for exhausts emitted by motor vehicles or other transportation facilities. This requirement shall also be applicable to the disposal of trash and waste materials. Windborne dust, dirt, fly ash, airborne solids, sprays, and mists (except water vapor) originating from any use shall be required to be conditioned and/or mitigated to below the Ringlemann No. 1 level.
Toxic or noxious matter
Toxic gases or noxious matter which can cause any damage to health, animals, vegetation, or other forms of property, or which can cause any excessive soiling beyond the property lines of the use shall not be permitted.
Odors
Operations, processes, or products shall not emit odors that are detectable at any point beyond the property lines of the use, except as otherwise exempted by section 16-167 (Exceptions).
Glare or heat
Any operation producing intense glare or heat shall be performed within an enclosed or screened area in such a manner that the glare or heat emitted will not be detectable from the property lines of the use.
Vibration
Every use shall be operated so that the ground vibration generated by the use is not harmful or injurious to any surrounding properties. No perceptible vibration (seen or felt without vibration detecting instruments) shall be permitted at any point beyond the property lines of the use.
Electricity and radioactivity
Radio and television transmitters shall be operated at the regularly assigned wave lengths (or within the authorized tolerances thereof) as assigned by the appropriate governmental agency. Subject to such exception, such transmitters shall be suitably wired, shielded, and controlled so that in operation they shall not emit any electrical impulses or waves beyond the lot lines which shall adversely affect the operation and control of any domestic household equipment or any other electronic devices and equipment.
Liquid and solid wastes
Liquid or solid wastes discharged from the premises shall be properly treated prior to discharge so as not to contaminate or pollute any watercourse or groundwater supply, nor to interfere with bacterial processes in sewage treatment. Such operations and uses shall comply with, and in some cases shall obtain all required permits by authorized governmental health and safety regulatory agencies having jurisdiction over such disposal activities. The disposal or dumping of solid wastes, such as slag, paper or fiber wastes, or other industrial wastes, shall not be permitted for any use.
Fire and explosive hazards
(A)   All activities involving the use or storage of combustible, flammable, or explosive materials shall be in compliance with nationally recognized standards, and shall be provided with adequate firefighting and fire-suppression equipment and devices in compliance with the current edition of the National Fire Protection Association regulations and in compliance with the city fire department.
(B)   Burning of waste materials in open fires is prohibited by State law.
Mechanical equipment
All mechanical and electrical equipment, including ground mounted equipment shall be completely screened behind a permanent structure or landscaping. All rooftop mechanical and electrical equipment shall be placed behind a permanent parapet screen or wall and shall be completely screened from any adjacent public street view except as otherwise permitted by project conditions of approval.
