No emission shall be permitted of odorous gases or other odorous matter in such quantities as to be readily detectable at the points of measurement specified in CVMC 19.66.060(A). Any process which may involve the creation or emission of any odors shall be provided with an adequate secondary safeguard system of control, so that control will be maintained if the primary safeguard system should fail. There is hereby adopted, as a guide in determining such quantities of offensive odors, Table III, “Odor Thresholds,” in Chapter 5 of the “Air Pollution Abatement Manual,” Copyright 1951, by Manufacturing Chemists Association, Inc., Washington, D.C., as subsequently amended. (Ord. 1212 § 1, 1969; prior code § 33.703(C)).
