(A) No stack shall emit more than 10 smoke units during any 1 hour, nor shall smoke of a density in excess of Ringelmann No. 2 be emitted, provided that during a single 1-hour period in each 24 hour day each stack may emit up to 20 smoke units when blowing soot or cleaning fires, and during such cleaning of fires, smoke of a density of Ringelmann No. 3 may be emitted, but not for longer than 4 minutes each period.
(B) No emission of smoke or particulate matter shall exceed a density of Ringelmann No. 3, except for a plume consisting entirely of condensed steam. For the purpose of grading the density of emission, the Ringelmann Chart published and used by the United States Bureau of Mines shall be employed.
(C) The rate of emission of particulate matter from sources within the boundaries of any lot shall not exceed a net figure of 1 pound per acre of lot area during any 1 hour.
(D) Dust and other forms of air pollution borne by the wind from such sources as storage areas, roads and so forth, within lot boundaries shall be kept to a minimum by appropriate landscaping, paving, oiling, or other acceptable means. The emission of particulate matter from such sources shall conform to the requirements of division (C) above.
(E) In addition to the performance standards specified herein, 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 hereby declared to be a public nuisance.
