Exemptions - The following uses and activities shall be exempt from the noise level regulations herein specified.

Of such opacity as to obscure an observer’s view to a degree equal to or greater than does smoke or contaminants in the standard prescribed by the ASTM except for when the presence of uncombined water is the only reason for failure to comply, or when such contaminants are emitted inside a building which prevents their escape into the atmosphere.

The emission of particulate matter from all sources shall not exceed 0.5 pounds per acre of property within the operation’s site per any one hour.

Open storage and open processing operations, including on-site transportation movements which are the source of wind- or air-borne dust or other particulate matter; or which involves dust or other particulate air contaminants, generating equipment such as used in paint spraying, grain handling, sand or gravel processing or storage or sand blasting, shall be so conducted that dust and other particulate matter so generated are not transported across the boundary line of the tract on which the use is located in concentrations exceeding four grains per 1000 cubic feet of air.

No use shall be located or operated which involves the emission of odorous matter from a source of operation where the odorous matter exceeds the odor threshold at the bounding property line or any point beyond the tract on which such use or operation is located.

The odor threshold as herein set forth shall be determined by observation by the City Manager or his or her designee.
