At the property line, the sound pressure level of noise radiated continuously from a facility shall not exceed the values given in division (A)(2) below.
      (2)   Sound-pressure levels. Maximum permissible sound-pressure levels of specified points of measurement for noise radiated continuously from a facility:
Band Cycles per Second (frequency)
Maximum Permitted Sound Level (decibels)

   (B)   Nuisance standards.
      (1)   Noise. Any use established shall conform to the noise standards established in Minn. Rules § 7030.0040, or as it may be amended from time to time. This standard shall not apply to incidental traffic, parking, loading, construction, farming, or maintenance.
      (2)   Vibration. Any use creating periodic, earthshaking vibration shall be prohibited if undue vibrations are perceptible beyond boundaries of the property on which the use is located. This standard shall not apply to vibrations created during the process of construction, or to permitted quarrying operations subject to conditions placed upon the businesses.
      (3)   Glare and heat. Any use producing intense heat or light transmission shall be performed with the necessary shielding to prevent the heat or light from being detectable at the lot line of the site on which the use is located.
      (4)   Smoke and particulate matter. Any use established, enlarged, or remodeled after the effective date of this subchapter shall be so operated as to meet the minimum requirements for ambient air quality standards, as established in M.S. Chapter 7009, as it may be amended from time to time, unless a permit has been secured from the county by the owner or operator of the facility or use.
      (5)   Toxic or noxious matter. Any use which involves the use of, or the manufacture of, toxic or noxious substances shall not discharge the substances into the atmosphere, water, or subsoil.
      (6)   Explosives. Any use requiring the storage, use, or manufacture of products which could decompose by detonation shall be located not less than 400 feet from any residence. This division (B)(6) shall not apply to the storage or usage, or liquefied petroleum or natural gas, for normal residential or business purposes.
      (7)   Radiation emission. All activities that emit radioactivity shall comply with the minimum requirements of the MPCA.
      (8)   Electrical emission. All activities that create electrical emissions shall comply with the minimum requirements of the FCC.
   (C)   Odor. No activity or operation shall cause, at any time, the discharge of toxic, noxious, or odorous matter beyond the limits of the immediate site where it is located in the concentrations as to be obnoxious or otherwise detrimental to, or endanger, the public health, welfare, comfort, or safety, or cause injury to property or business.
   (D)   Glare. Glare, whether direct or reflected, such as from floodlights, spotlights, or high-temperature processes, and as differentiated from general illumination, shall not be visible beyond the site of origin at any property line.
   (E)   Exterior lighting. Any lights used for exterior illuminations shall be directed away from adjacent properties.
   (F)   Smoke, dust, fumes, or gases. Every operation shall conform to local standards.
   (G)   Hazard. Every operation shall be carried on in accordance with local fire and safety codes.
   (H)   Water supply. The design and construction of water supply facilities and water supply source shall be in accordance with local and state Department of Health standards and requirements.
   (I)   Waste. All sewage and industrial wastes shall be treated and disposed in the manner as to comply with the State Department of Health standards and requirements, and local codes.
   (J)   Compliance. In order to assure compliance with the performance standards set forth above, the Planning Commission may require the owner or operator of any permitted use to make the investigations and tests, as may be required, to show adherence to the performance standards.
   (K)   Additions. All subsequent additions and outbuildings constructed after the erection of an original building, or buildings, shall be reviewed by the Planning Commission.
