CITY OF CHICAGO, ILLINOIS AIR POLLUTION CODE CHAPTER 17 17-24. amended January 1, 1964) Subject to the provisions of Section 17-25, it shall be unlawful within the City of Chicago for any person owning or in charge of any fuel-burning, combustion or process equipment or device, or any portable boiler, to cause, suffer or allow the emission from any such source of any particulate matter except in conformity with the limits set forth as follows: (1) The basic limitation on the average emission into the atmosphere of particulate matter from any single source of emission shall be 0.35 grains per cubic foot of gas measured at a temperature of 60 degrees Fahrenheit and a pressure of 30 inches of mercury, under steady conditions, provided that for emissions at levels 100 feet or more above grade, the basic limitation shall be increased by the amount of particulate matter of less than 10 microns in size, if any, up to a maximum increase of 0.03 (H/100) grains per scf, where H is the height of discharge in feet above grade. (2) The limitation on the emission of that portion of the particulate matter which is 44 microns in size or larger from any single such source shall be 0.21 grains per scf. 17-38. It shall be unlawful for any person to operate any surface burning type (hand fired) of combustion equipment with any solid fuel other than a low volatile solid fuel unless: (1 The Director has issued a Certificate of Operation therefor in accordance with Section 17-55 or Section 17-60, authorizing the use of other than low volatile solid fuel with such equipment; (2) The Director has approved the equipment or type of equipment in accordance with Section 17-44; (3) The Director has issued an Allowable Fuel Certificate for such equipment in accordance with Sections 17-41, 17-42, and 17-43; or (4) The Appeal Board has granted an individual variance for such equipment in accordance with Section 17-74. The foregoing restrictions shall not apply with respect to the burning of combustible refuse in such equipment in accordance with rules and regulations issued by the Director. 17-39. A solid fuel containing volatile matter in excess of 23% on an ash free basis shall be considered a low volatile solid fuel provided it meets the same standards in regard to smoke production as a low volatile solid fuel, and subject to the following conditions in order to ascertain whether or not such standards are met: Adequate supplies of such solid fuel shall be made available to the Director to conduct such reasonable tests as he shall deem necessary to determine that such fuel meets the standards herein before established. The reasonable expense of any such tests shall be borne by the person seeking the approval of such solid fuel. The Director shall maintain and, upon request, furnish a list of brands or trade names of solid fuels which have been tested for conformity with the provisions of this chapter and which as a result of such tests have been approved. 17-40. Solid fuel, other than low volatile solid fuel, may be used or consumed only in mechanical combustion equipment or mechanically fired apparatus; except that after suitable inspections and tests have proven to the Director that any combination of surface burning type (hand-fired) of equipment and appurtenances and fuel can comply with the emission limitations established by or under this chapter, the Director shall approve the use of such combination of equipment and fuel. CITY OF DETROIT, MICHIGAN OFFICIAL AIR POLLUTION CONTROL CODE ORDINANCE NO. 167-E ARTICLE 2 (effective November 6, 1964) Section 2.4A It shall be unlawful within the City of Detroit for any person, firm or corporation to permit the emission of any particulate matter from any source whatsoever in excess of the emission schedule listed below: 100 to 300 300 to 800 800 and over 0.30 0.65 0.65 to 0.45 (c) 0.45 to 0.30 (c) 0.30 Fuel burning and incinerator emission limitations shall be corrected to 150 per cent total air. The operating limitation allows for gradual deterioration of equipment performance during extended periods of continuous operation where it is impractical to maintain design conditions for these extended periods. (See Regulation No. 1, Section 2.4 for further details on intent.) Emission limitation for specific ratings are determined by linear interpolation between the ranges shown. When wet collectors or scrubbers are utilized, that portion of water vapor in the exhaust gases which was added for collector or scrubber requirements shall be deleted from the total exhaust gases in calculating the particulate emission rate. Supplemental Regulations Section 2.4 Regulation No. 1 DESIGN AND OPERATING EMISSION LIMITATIONS This Regulation clarifies the intent of Section 2.4A for those cases where both design and operating emission limitations are stipulated for a given operation. The design emission standard shall be met when the system is field operated as close to design conditions as is reasonably feasible. In addition, before a permit is issued for the installation of a collector sufficient data will be required to be submitted to the Department in the form of tests, drawings, calculations, etc., to prove that when the collector is operated at design conditions the particulate loading will not exceed the design emission limitation. The operating emission limitation is less stringent than the design emission limitation and recognizes that field operating conditions do not always meet design conditions and that this could cause a temporary degradation in over-all equipment performance. The more lenient operating emission standard shall not be used as a basis for design. It also shall not be used as a basis for reducing design collector efficiency to effectuate savings in operating cost. Section 4.9 Regulation No. 1 COLLECTOR REQUIREMENT FOR SINGLE RETORT STOKER- New forced draft solid fuel fired boilers of less than 400 H. P. nominal rating and existing boilers in this category when stack or breeching is replaced shall be provided with a low draft loss collector or drop out box approved by the Bureau.
