The L-1 Light Industrial District is intended to control the development of lands to be used by industrial firms that have high standards of performance and that can locate in close proximity to residential and business uses without creating nuisances. The District regulations are designed to permit the operations of manufacturing, wholesaling and warehousing activities with adequate protection to adjacent district uses and sufficient control of external effects to protect one industry from another and particularly where such light industrial uses adjoining uses in other than industrial zoning districts. In this District, outdoor storage must be completely screened and all industrial operations must be in an enclosed building.

1. General Conditions:
   1. Minimum Contiguous District Area: The minimum contiguous area for any land zoned in accordance with the L-1 District shall be ten (10) acres.
   2. Sanitary Sewer and Potable Water: All uses shall be connected to and maintain potable water supply and sanitary sewer facilities at the expense of the owner and/or developer of the property.
   3. Refuse Screening Enclosures Required: All refuse shall be stored in appropriate containers and completely screened so as to not be visible to any street or public right of way. Such screening shall be solid and six feet to eight feet (6' to 8') in height.
   4. Enclosure of Uses: All uses within the Light Industrial District shall be conducted wholly within enclosed buildings except otherwise permitted by this Chapter. All outdoor storage facilities for fuel, raw material and products shall be effectively screened and enclosed by a solid wall or fence at least eight feet (8') in height; provided, that if such materials are in excess of eight feet (8') in height, then landscape screening shall be provided in addition to the fence or wall, equal or exceeding the height of the fence and materials to be stored outdoors. Such outside storage must be located behind the front of any building facing a public street.
   5. Lighting: All exterior lighting, building and parking lot lights and landscape lighting shall be directed away from adjacent highways, streets and properties. A lighting plan shall be prepared and be reviewed and approved by the Building Commissioner.
   6. Processes and equipment employed, and goods processed or sold, shall be limited to those which are not objectionable by reason of odor, dust, cinders, gas, noise, vibrations, particulate matter, or water carried waste.
   7. No activities involving the storage, utilization or manufacture of materials or products which decompose by detonation shall be permitted, except such as are specifically licensed by the Village. Such materials shall include, but shall not be confined to: all primary explosives such as lead azide, lead styphnate, fulminates, and tetrocene; all high explosives such as TNT, RDX, HMX, PETN and picric acid; propellants and components thereof such as nitro-cellulose, black powder, boron dydrides, hydrazine, and its derivatives; pyrotechnics and fireworks such as magnesium powder, potassium chlorate and potassium nitrate; blasting explosives such as dynamite and nitroglycerin; unstable organic compounds such as acetylides, tetrazoles, perchloric acid, parchlorates, chlorates, hydrogen peroxide in concentration greater than thirty five percent (35%); and nuclear fuels, fissionable materials, and products and reactor elements such as Uranium 235 and Plutonium 239.
   8. Any use established in the L-1 Light Industrial District shall be operated in such a manner as to comply with applicable performance standards as hereinafter set forth governing noise, smoke, particulate matter, toxic or noxious matter, odors, fire and explosive hazards, or vibration, glare or heat. No use already established on the effective date of this Title shall be so altered or modified as to conflict with such applicable performance standards. The application for a building permit for a new establishment or change of use, when requested by the Village Administrator, must be accompanied by a verification from a recognized testing laboratory that all performance standards contained herein will be reasonably met.
   9. Signs: All signs shall conform to the applicable requirements set forth in Title 9A, Chapter 8 and the approved site plan.

Noises capable of being so measured, for the purpose of this Title, shall be those noises which cause rapid fluctuations of the needle of the sound level meter with a variation of no more than plus or minus two (2) decibels. Noise incapable of being so measured, such as those of an irregular and intermittent nature, shall be controlled so as not to become a nuisance to adjacent uses. At no point on a lot line shall the sound intensity level of any individual operation or plant (other than the operation of motor vehicles or other transportation facilities) exceed the decibel levels in the designated octave bands shown in the following table:
   Maximum Permitted Sound Level (Decibel)
   Octave Band
   
   

   (Frequency Cycles Per Second)	Along Residence District Boundaries	Along Other Lot Lines

Smoke and Particulate Matter: The emission of smoke or particulate matter in such manner quantity as to endanger or to be detrimental to the public health, comfort or welfare is hereby declared to be a public nuisance and shall be unlawful. For the purpose of grading the density of smoke, the Ringelmann Chart, published and used by the United States Bureau of Mines, shall be employed. The emission of smoke or particulate matter of a density greater than No. 2 on the Ringelmann Chart is prohibited at all times, except as otherwise provided hereinafter. The emission from a source within any lot area of particulate matter containing more than ten percent (10%) by weight of particles, having a particle diameter larger than forty four (44) microns is prohibited. Dust and other types of air pollution, borne by the wind from such sources as storage areas, yards, roads and the like within lot boundaries, shall be kept at a minimum by appropriate landscaping, paving, oiling, fencing or other acceptable means. Emission of particulate matter from such sources in excess of the weight limitation hereinafter specified is prohibited. The emission of more than eight (8) smoke units per hour per stack is prohibited, including smoke of a density in excess of No. 2 on the Ringelmann Chart. During one one-hour period in each twenty four (24) hour day, however, each stack may emit up to sixteen (16) smoke units when blowing soot or cleaning fires.

4. Odors: The emission of odorous matter in such quantity as to be readily detectable at any point along a lot line or as to produce a public nuisance or hazard beyond a lot line is prohibited.
5. Fire and Explosion Hazard: The storage, utilization or manufacture of solid materials or products ranging from free or active burning to intense burning is permitted, provided the following condition is met: said materials or products shall be stored, utilized or manufactured within completely enclosed buildings having incombustible exterior walls and protected throughout by an automatic re-extinguishing system.
   The storage, utilization or manufacture of flammable liquids, or materials which produce flammable or explosive vapors or gasses, shall be permitted in accordance with the following table, exclusive of storage of finished products in original sealed containers, which shall be unrestricted:
   Total Capacity of Flammable Materials Permitted (In Gallons)

6. Glare and Heat: In the L-1 Light Industrial District any operation producing intense glare or heat shall be performed within a completely enclosed building in such manner as not to create a public nuisance or hazard along lot lines. Exposed sources of light shall be shielded so as not to illuminate other property.
7. Vibration: No industrial operation or activity shall cause at any time ground transmitted vibrations in excess of limits set forth below. Vibration (the periodic displacement, measured in inches, of earth) shall be measured at any point along a lot line with a three (3) component measuring instrument and shall be expressed in inches as follows:
   
   

   Frequency (cycles per second)	Maximum Permitted Displacement Along Lot Lines (in inches)
   0 to 10	.0008
   10 to 20	.0005
