The intent and purpose of the following performance standards is to allow for industrial operations with high standards for site development and use performance. These performance standards shall apply to all uses allowed within the Industrial District. Applicants may be required by the Planning Commission to submit studies, reports and additional information relative to how a proposed use will meet the performance standards described in this section. This includes, but is not limited to: noise studies, odor maps, engineering analysis of proposed vibrations, emission maps, schematics and renderings of the proposed buffers and buildings when viewed from the adjoining property.
(a) Control of Smoke, Dust, Fly Ash, and Gases. The emission of smoke, dust, fly ash and gases shall in no manner be unclean, destructive, unhealthful, hazardous or deleterious to the general welfare. Such emission shall be in strict conformance with all new source standards of performance promulgated under the Federal Clean Air Act for sulfur dioxide, hydrogen chloride, oxides of nitrogen, carbon monoxide, lead, cadmium, mercury, dioxin, dibenzofurans, particulate matter, opacity and other post-combustion concentrations of surrogate substances, as well as all applicable State and County health laws as pertaining to air pollution and smoke abatement.
(b) Control of Odors. There shall be no emission of odorous matter in such quantities as to be offensive at lot boundary lines.
(1) Any process which may involve the creation or emission of any odor shall be provided with a secondary safeguard system, so that control will be maintained if the primary safeguard system fails.
(2) 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’ Association, Inc., Washington, D.C.
(c) Control of Glare or Heat. Any operation producing intense glare or heat shall be performed within an enclosed building or behind a solid fence in such a manner as to be completely imperceptible from any point beyond the lot lines of the lot upon which the source of such glare or heat is located.
(d) Control of Vibrations. No vibration which is discernible to the human sense of feeling shall be perceptible at any point beyond the lot line of the lot upon which the source of such vibration is located.
(e) Control of Excessive Noise. Noise emanating from operations within the Industrial District shall conform to the noise standards described in Section 1288.27 of this zoning ordinance.
(f) Control of Radioactivity or Electrical Disturbances. No radioactive materials shall be emitted in excess of standards established by the U.S. Bureau of Standards for human safety. There shall be no electrical disturbance (except from domestic household appliances) adversely affecting the operation of any equipment located beyond the property of the creator of such disturbance.
(g) Outdoor Storage and Waste Disposal.
(1) No flammable or explosive liquid, solid or gas shall be stored in bulk above ground. However, tanks or drums of fuel directly connecting with energy devices, heating devices or appliances located on the same lot as the tanks or drums of fuel are excluded from this provision. The storage and handling of any flammable materials used on site shall comply with all State rules and regulations, and regulations as established by the Fire Prevention Act, Act 207, P.A. of 1941, as amended. If located above ground, storage tanks shall provide secondary containment. If located below ground, storage tanks shall provide corrosion protection and spill/overfill prevention systems. Furthermore, all storage tanks for flammable liquid materials above ground shall be located at least 150 feet from all property lines. No outdoor storage shall be visible from abutting lots that are zoned for residential purpose or zoned “Technology.”
(2) All outdoor storage facilities for fuel, raw materials and products shall be enclosed by a fence adequate to conceal the facilities from any adjacent properties and to prevent spillage onto all adjacent properties and into storm sewers.
(3) No material or waste shall be deposited upon a lot in such a form or manner that the same may be transferred off the lot by natural forces or causes.
(4) All material or waste which might cause fumes or dust or which constitutes a fire hazard or which may be edible or otherwise be attractive to rodents or insects shall be stored outdoors only in closed containers.
(h) Control of Water Pollution. Pollution of water shall be subject to such requirements and regulations as are established by the Michigan State Department of Health, the Michigan Water Resources Commission, the Genesee County Health Department, and the U.S. Environmental Protection Agency. Such requirements and regulations shall apply in all cases except when they are less stringent than the following standards, in which case the following standards shall apply:
(1) No untreated or polluted wastes shall be discharged in the public sewer, storm sewer, or sanitary sewer system which are dangerous to the public health and safety.
(2) Acidity or alkalinity shall be neutralized to a pH of 7.0 as a daily average on a volumetric basis, with a maximum temporary variation of pH 5.0 to 10.0.
(3) Wastes shall contain no cyanides and no halogens (chlorine, iodine, bromine, and flourine) and shall contain not more than ten ppm of the following gases: hydrogen sulfite, sulfur dioxide, and nitrous oxide.
(4) Wastes shall not contain any insoluble substance in excess of 10,000 ppm or exceeding a daily average of 500 ppm or fail to pass a No. 8 Standard sieve, or have-a dimension greater than one-half inch.
(5) Wastes shall not have chlorine demand greater than 15 ppm.
(6) Wastes shall not contain phenols in excess of 0.005 ppm.
(7) Wastes shall not contain any grease or oil or any oil substance in excess of 100 ppm or exceed a daily average of 25 ppm.
(i) Floor Drains. General purpose floor drains in work and storage areas of operations within the Industrial District are prohibited except in facilities which do not store or use flammable or combustible materials and under one of the following conditions:
(1) Holding Tank. The drain(s) are connected to a holding tank or sump which is pump out and hauled away for proper disposal.
(2) Permit from City. A permit is obtained from the City to permit the drain(s) to be connected to the sanitary sewer system.
(3) Permit from State. A State ground water discharge permit is obtained.
(j) Fire Department Requirements. The owner and/or operator of each facility in the Industrial District shall comply with City Fire Department information requests to ensure compliance with the Michigan Occupational Safety and Health Act (PA 154 of 1974) and the Michigan Fire Prevention Code (PA 207 of 1941).
