  8. Performance Standards
    1. Compliance Required: No land or building in the “IP” District shall be used or occupied in any manner so as to create any dangerous, injurious, noxious, or otherwise objectionable fire, explosive, or other hazard, noise or vibration, smoke, dust, odor, or other form of air pollution; heat, cold, dampness, electrical or other substance, condition or element (referred to herein as “dangerous or objectionable elements”) in such a manner or in such amount as to adversely affect the surrounding area or adjacent premises; provided that any use permitted by this Section may be undertaken and maintained if it conforms to the regulations of this Section limiting dangerous and objectionable elements at the point of determination of their existence.
    2. Enforcement Provisions: Even though compliance with performance standards procedure in obtaining a Certificate of Occupancy is not required for a particular use, initial and continued compliance with performance standards shall be enforced by the Building Inspector against any use if there are reasonable grounds to believe that performance standards are being violated by such use.
    3. Locations Where Determinations Are To Be Made For Enforcement Of Performance Standards: The determination of the existence of any dangerous and objectionable elements shall be made at the location of the use creating the same and at any point or points where the existence of such elements may be more apparent (herein referred to as “at any point”).
  9. Performance Standard Regulations
    The following provisions, standards and specifications shall apply:
    1. Fire and Explosion Hazards: All activities involving and all storage of inflammable and explosive materials shall be provided at any point with adequate safety devices against the hazard of fire and explosion, and adequate fire-fighting and fire suppression equipment and devices standard in the industry. Burning of waste materials in open fires shall be prohibited at any point.  The relevant provisions of State and local laws and regulations shall also apply.
    2. Radioactivity or Electric Disturbance: No activities shall be permitted which 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 a disturbance.
    3. Noise: At the points of measurement which shall be at the property line, the sound pressure level of noise radiated from a facility at nighttime shall not exceed 40 decibels or the average sound level of the street traffic noise nearest the noise generator, whichever is the higher, in any octave band of frequency above 300 cycles per second.  The sound pressure level shall be measured with a Sound Level Meter, and an Octave Band Analyzer that conforms to the specifications published by the American Standards Association. Noise shall be so muffled or otherwise controlled, as not to become objectionable, due to intermittence, beat frequency, impulsive character (hammering, etc.), periodic character (humming, screeching, etc.), or shrillness. For facilities which radiate noise only during a normal daytime working shift, the allowable decibel sound pressure level maximum given above may be increased 25 decibels, or 10 decibels above the average sound level of the street traffic noise nearest the noise generator, whichever is the higher. Sirens, whistles, bells, etc., which are maintained and utilized solely to serve a public purpose (such as fire and air raid warning sirens) are excluded from the above regulations.
    4. Vibration: No vibration shall be permitted which is discernible without instruments at the property line.
    5. Smoke: No emissions shall be permitted, at the point of discharge from any chimney or otherwise, of visible gray smoke of a shade equal to or darker than No. 2 on the Power’s Micro-Ringlemann Chart, published by McGraw-Hill Publishing Company, Inc. and copyrighted 1954 (being a direct facsimile reduction of the standard Ringlemann Chart as issued by the United States Bureau of Mines), except that visible gray smoke of a shade equal to No. 2 on said Chart may be emitted for 4 minutes in any 30 minutes.  These provisions applicable to visible gray smoke shall also apply to visible smoke of a different color but with an apparently equivalent capacity.
    6. Odor: No emission shall be permitted of odorous gases or other odorous matter in such quantities as to be offensive at the property line.  Any process which may involve the creation or emission of any odors shall be provided with a secondary safeguard system, so that control will be maintained should the primary safeguard system fail.  There is hereby established as a guide in determining such quantities of offensive odors, Table III, “Odor Thresholds”, in Chapter 5, “Air Pollution Abatement Manual”, copyright 1951 by Manufacturing Chemists’ Assn., Inc., Washington, D.C.
    7. Fly Ash, Dust, Fumes, Vapors, Gases and Other Forms of Air Pollution: No emission shall be permitted which can cause any damage to health, to animals, vegetation, other forms of property, or which can cause any excessive soiling, at any point; and in no event shall any emission, from any chimney or otherwise, of any solid or liquid particles in concentrations exceeding 0.3 grains per cubic foot of the conveying gas at any point, be permitted.  For measurement of the amount of particles in gases resulting from combustion, standard corrections shall be applied to a stack temperature of 500 degrees Fahrenheit and 50 percent excess air.
    8. Glare: No direct or sky-reflected glare from high-temperature processes, such as combustion or welding or otherwise, so as to be visible at the property line, shall be permitted. This restriction shall not apply to signs otherwise permitted by the provisions of this Section.
    9. Liquid or Solid Waste: No discharge shall be permitted at any point into any public sewer, private sewage disposal system, or stream, or into the ground, except in accordance with standards approved by the Department of Health of the State of Texas or standards equivalent to those approved by such department for similar uses; nor shall the discharge of any materials of such nature or temperature as can contaminate any water supply or otherwise cause the emission of dangerous or offensive elements be permitted.
