Smoke and Particulate Matter. The emission of smoke and dusts by manufacturing plants in an amount sufficient to create a general nuisance to adjoining properties shall be prohibited. Total emission of smoke and particulate matter shall be limited to the following: | |||
Ringelmann Requirements. All smoke and the emission of all other particulate matter in quantities sufficient to produce an opacity at any point greater than what Ringelmann level is prohibited. | 2 | 3 | |
The emission of smoke or dusts in an amount sufficient to create a general nuisance to occupants of adjoining properties or to the occupants in the general area wherein the use is located shall be prohibited. | x | ||
Odors. No odor shall be emitted by any use permitted in this district in such quantities as to be detectable by an average observer at any point on the boundary line of the premises or beyond the nearest residential or business district. | x | x | x |
Noxious Gases. Processes and operations of uses capable of dispersing noxious gases or toxic particulates into the atmosphere are prohibited. | x | ||
Processes and operations of permitted uses capable of dispersing noxious gases or toxic particulates into the atmosphere must be hooded or otherwise suitably enclosed. The emission of such noxious gases or toxic particulates shall be from a stack not less than how many feet in height? | x 35' | x 25' | |
