' ARTICLE 9 : EMISSION STANDARDS SECTION 9.03 EMISSION OF AIR CONTAMINANT: VISUAL STANDARD ' Adopted 03/13/68(12)Revised 07/08/70(126),04/11/73(186),06/09/88(621)05/11/89(643),09/08/94(798),04/09/98(865), 03/11/99(881),03/25/04(1024) (a) It shall be unlawful for any person to cause or allow the emission of any air ' contaminant for a period or periods aggregating more than 3 minutes in any 1 hour, which is: (1) Darker in shade than that designated as No. 1 (20% density) on the Ringelmann ' Chart, as published by the United States Bureau of Mines; or ' (2) Of such opacity as to obscure an observer's view to a degree equal to or greater than does smoke described in Section 9.03(a)(1). (b) The density or opacity of an air contaminant shall be measured at the point of its emission, except when the point of emission cannot be readily observed, it may be measured at an observable point of the plume nearest the point of emission. (c) This section shall not apply when the presence of uncombined water is the only reason for the failure of the emission to meet the requirements of this section. (d) This section shall not apply to solid fuel burning devices, permitted fire training ' facilities, permitted obscurant usage during military training operations, outdoor fires, motor vehicles when operated on public roads, aircraft, or equipment subject to Section 9.04 of this regulation. (e) This section shall not apply to equipment with an alternate opacity standard issued under Section 3.03 or Article 6 of this regulation that is based upon a correlation with ' the particulate concentration and that accurately indicates a violation of the applicable particulate emission standards in Section 9.09 of this regulation. SECTION 9.04 OPACITY STANDARDS FOR EQUIPMENT WITH ' CONTINUOUS OPACITY MONITORING SYSTEMS Adopted 04/09/98(865) Revised 03/25/04(1024) (a) Applicability. This section shall apply to all equipment required to be equipped with a continuous emission monitoring system for opacity. (b) It shall be unlawful for any person to cause or allow the operation of any of the ' following equipment unless equipped with a continuous emission monitoring system for opacity: (1) Cement kilns; 1 (2) Clinker coolers; (3) Glass furnaces, rated at greater than 1 ton per hour, that burn fuel; ' (4) Fuel burning equipment, rated at 100 million Btu per hour or greater, that burns wood, coal, or residual oil; and (5) Refuse burning equipment rated at greater than 12 tons per day. (c) It shall be unlawful for any person to cause or allow the emission of any air ' contaminant from any equipment subject to this section during any hour that: Page 1 of 7
