§ 38-1453. Odor.

(a)

No use or operation shall be located or operated in the C-3 commercial district, or the I-1, I-2 or I-3 industrial district which involves the emission of odorous matter which exceeds the odor threshold at the bounding property line or at any point beyond the tract on which the use or operation is located.

(b)

No use or operation shall be located or operated in the I-4 or I-5 industrial district which involves the emission of odorous matter which exceeds a concentration at the bounding property line or at any point beyond which, when diluted with an equal volume of odor-free air, exceeds the odor threshold.

(c)

The odor threshold as herein set forth shall be determined by observation by the enforcing officer. In any case, where uncertainty may arise, or where the operator or owner of an odor-producing use may disagree with the enforcing officer, or where specific measurement of odor concentration is required, the method and procedure, specified by the American Society for Testing Materials 1391-57 entitled: "Standard Method for Measuring Odor in Atmospheres," shall be used, and a copy of such publication is hereby incorporated in this resolution by reference.
