1. Industrial Performance Standards. The following performance standards are intended to ensure that all industries will provide necessary modem control methods to protect the Town from hazards and nuisances; to set objective, quantitative standards for the maximum tolerated levels of frequently-hazardous or annoying emissions; and to protect any industry from arbitrary exclusion or persecution based solely on the characteristics of that type of industry's past uncontrolled operation.
   1. General.
      1. No land or building devoted to uses authorized by this chapter shall be used or occupied in any manner so as to create 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, glare, electrical or other disturbance; liquid or solid refuse or waste; or other substance, condition, or element in such a manner or in such an amount as to affect adversely the surrounding area or adjoining premises. The foregoing are hereinafter referred to as "dangerous or objectionable elements."
      2. In addition to meeting other application requirements for site plan approval or a conditional use permit, parties seeking approval for an industrial use shall include in the application a description of the proposed machinery, products, and processes to be located at the development If, in its opinion, the proposed use may cause the emission of dangerous or objectionable elements, the Planning Commission may require the application include an investigation and report from one or more expert consultants qualified to advise as to whether a proposed use will conform to the applicable performance standards specified in this Chapter. Such consultant shall report as promptly as possible. A copy of such report shall be promptly furnished to the applicant The cost of such expert report shall be borne by the applicant.
      3. Within twenty (20) days after the Commission has received the aforesaid application or report, if a report was required, or within such period as agreed to by the applicant, the Commission shall determine whether reasonable measures are being employed to assure compliance with the applicable performance standards. On such basis, the Commission may approve or refuse to approve the use or may require a modification of the proposed plans, construction specifications, device or operation, and shall so inform the Planning and Zoning Commission.
      4. Any Zoning Certificate so authorized and issued shall evidence only that reasonable measures are being taken. It shall not relieve the applicant of the responsibility of meeting such standards when the plant is actually in operation; and, in case of a failure to perform in accordance with the standards, whatever additional devices or modifications in process shall be necessary to achieve full compliance with the standards shall be the sole responsibility of the applicant.
      5. The Planning and Zoning Commission shall investigate any purported violation of performance standards; and, if necessary for such investigation, may request that the Planning Commission employ qualified experts. If, after public hearing and due notice, the Planning Commission finds that a violation has existed or does exist, it shall order the Planning and Zoning Commission to serve notice that compliance with the performance standards must be achieved within a specified period of time or the plant be shut down. Should the violation of performance standards threaten the public health, convenience, or welfare, the Planning Commission may order the offending plant to cease operation until proper steps are taken to correct the conditions which cause the violation. The services of any qualified experts, employed by the Planning Commission to advise in establishing a violation, shall be paid by the violator if said violation is established, otherwise by the Town.
      6. The determination of the existence of dangerous and objectionable elements shall be made at any point; provided, however, that the measurements having to do with noise, vibration, odors, or glare, shall be taken at the lot line of the establishment or use.
   2. Dangerous and Objectionable Elements.
      1. Noise. No use shall emit or cause the emission of sound from a stationary source such that the one hour equivalent sound level L_eq of resultant sound measurement, at the lot line of the establishment or use, that exceeds by 6 dba or more, the one hour equivalent sound level (L_eq) cause by ground transportation as estimated for that point of measurement and that time of day, pursuant to FHWA-RD-77-108 Highway Traffic Noise Prediction Model, or by other techniques at least as accurate. The sound level measuring instrumentation shall conform with ANSI S1.4-1971 Type 1, and the measurement procedure shall be compatible with that, according to ANSI S 1.13- 1971, with the following adjustments:
         1. Adjustment for Temporal and Tonal Characteristics of Sound. If the sound has a pronounced audible tonal quality such as a whine, screech, buzz, or hum, or if the sound has an audible cyclic variation in sound level such as beating or other amplitude modulation, 5 dba shall be added to the measured sound level to allow for increased subjective response to the sound.
         2. Quasi-Steady Impulsive Sound. Where the sound is of a repetitive impulse nature so that a steady reading is obtained using the "slow response" setting on the sound level meter, then 10 dba shall be added to the measured value to allow for the increased subjective response to the sound.
            
            An adjustment may be made under only one of subsection (1) and (2). In a case where both subsections apply, then subsection (2) takes precedence. No use shall emit or cause or permit the emission of sound of an impulsive nature from a stationary source such that it results in an impulsive sound level at a point of measurement in excess of 80 dba or in a one hour equivalent level (L_eq) exceeding that one hour equivalent level (L_eq) cause by ground transportation as estimated for that point of measurement and that time of day, pursuant to FHW ARD-77-1 08 or equivalent method.
      2. Vibration. No vibration (other than from transportation facilities or temporary construction work) shall be permitted which is discernible without instruments at the points of measurement.
      3. Odors. No emission of odorous gases or other odorous matter shall be permitted in such quantities as to be readily detectable when diluted in the ratio of one volume of odorous air to four volumes of clean air at the point of greatest concentration. 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 if the primary safeguard system should fail.
      4. Glare. No direct or sky-reflected glare, whether from flood lights or from high temperature processes such as combustion or welding or otherwise, shall be permitted which penetrates beyond the property upon which the light source is located in a manner constituting a nuisance or hazard.
      5. Fire and Explosion Hazards. All activities involving, and all storage of flammable 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 is prohibited at any point.
      6. Air Pollution. No particulate or gaseous pollutants shall be emitted into the air in violation of the Utah State Air Conservation Act, its amendments, or resulting regulations.
      7. Liquid or Solid Wastes. No discharge at any point into a public sewer, public waste disposal system, private sewage system, or stream, or into the ground shall be allowed contrary to the Utah State Water Pollution Control Act, its amendments, the subsequent Wastewater Disposal Regulations, or the Utah Code of Solid Waste Disposal Regulations.
