No stack shall emit more than thirty (30) smoke units during one hour nor shall smoke of a density in excess of Ringlemann No. 2 be emitted; provided, that during fire-cleaning periods each stack may emit four minutes of smoke of a density of Ringlemann No. 3, and eight minutes of smoke of a density of Ringlemann No. 2, and during soot blowing periods eight minutes of smoke of a density of Ringlemann No. 2.

2.

No emission of smoke or particulate matter shall exceed a density of Ringlemann No. 3, except for a plume consisting entirely of condensed steam. For the purpose of grading density of emission the Ringlemann chart published and used by the United States Bureau of Mines shall be employed.

3.

The rate of emission of particulate matter from all sources within the boundaries of any lot shall not exceed a net figure of 8.97 kilograms per hectare (eight (8) pounds per acre) of lot area during any one (l) hour

4.

Dust and other forms of air pollution borne by the wind from such sources as storage areas, yards, roads and so forth, within lot boundaries shall be kept to a minimum by appropriate landscaping, paving, oiling or other acceptable means.

5.

In addition to the performance standards specified in this section, the emission of smoke or particulate matter in such manner or quantity as to be detrimental to or endanger the public health, safety, comfort or welfare is declared to be a public nuisance.

C.

Odorous Matter. The emission of odorous matter from any property in such concentrations as to create a public nuisance or hazard beyond the boundaries of said property is prohibited.

D.

Vibration. Any process or equipment which produces intense earth-shaking vibrations, such as are created by heavy drop forges or heavy hydraulic surges, shall be set back at least 150 meters (five hundred (500) feet) from the boundary of any residence or business district unless such process or equipment is so controlled as to prevent the transmission beyond the said district boundary of earth-shaking vibrations perceptible without the aid of instruments. However, in no case shall such vibrations be allowed to create a public nuisance or hazard beyond the property line.

E.

Toxic or Noxious Matter. No use on any property shall discharge across the boundaries of said property toxic or noxious matter in such concentrations as to be detrimental to or endanger the public health, safety, comfort or welfare, or cause injury or damage to other property or business.

F.

Glare or Heat. Any operation producing intense glare or heat shall be performed within a completely enclosed building and effectively screened in such a manner as not to create a public nuisance or hazard along property boundaries. Exposed sources of light shall be shielded so as not to create a nuisance across lot lines.

G.

Fire and Explosive Hazards. Fire and explosive hazards shall be controlled as follows:

1.

Activities involving the storage or manufacture of materials or products which decompose by detonation are not permitted in the M-2 district unless licensed by the city.
