(A) Physical appearance. All operations shall be carried on within an enclosed building except that new material or equipment in operable condition may be stored in the open. Normal daily wastes of an inorganic nature may be stored in containers not in a building when such containers are not readily visible from the street.
(B) Fire hazard. No operation shall involve the use of highly flammable gases, solids, acids, liquids, grinding processes, or other inherent fire hazard. This provision shall not be construed to prohibit the use of normal heating fuels, motor fuels, and welding gases when handled in accordance with other city ordinances.
(C) Noise. No operation shall be carried on which involves noise in excess of the normal traffic noise of the adjacent street at the time of the high traffic hour. Noise shall be measured by observation with the natural senses, a suitable instrument may be used and measurement may include breakdowns into a reasonable number of frequency ranges. All noises shall be muffled so as not to be objectionable due to intermittence, beat frequency, or shrillness.
(D) Sewage and liquid waste. No operation shall be carried on which involves the discharge into a sewer, watercourse, or the ground of liquid wastes of any radioactive nature, or liquid wastes of a chemical nature which are detrimental to normal sewage plant operation or corrosive and damaging to sewer pipes and installation.
(E) Air contaminants. Due to the fact that the possibilities of identifying all air contaminants cannot reasonably be covered in this section, there shall be applied the general rule that there shall be no discharge unless such discharge occurs naturally, without human intervention, from any source whatsoever such quantities of air contaminants or other material as may cause injury, detriment, nuisance, or annoyance to any person, or to the public in general or as to endanger the comfort, repose, health, or safety of residents or to cause or have a natural tendency to cause injury or damage to business, vegetation, or property.
(F) Gases. The gases sulfur dioxide and hydrogen sulfide shall not exceed five parts per million. All nitrous fumes shall not exceed one part per million. Measurements shall be taken at the property line of the particular establishment involved.
(G) Vibration. All machines including punch presses and stamping machines shall be mounted so as to minimize vibration and in no case shall such vibration exceed a displacement of three thousandths of an inch measured at the property line.
(H) Glare and heat. All glare, such as welding arcs and open furnaces, shall be shielded so that they shall not be visible from the property lines. No heat from furnaces or processing equipment shall be sensed at the property line to the extent of raising the temperature of air or materials more than 5°F.
