TABLE OF CONTENTS All standards, unless otherwise indicated, refer to places where people live or an undesirable effect could result from levels above the standard. d Potassium iodide colorimetric method of measurement. Use background value of 5.0 tons/sq mi/mo in all areas. e Total dustfall including water soluble and water insoluble and all other components. A. As used in these regulations, except as otherwise specifically provided in such regulations and except where the context indicates otherwise, the following words shall have the meaning ascribed to them in this regulation: 1. Approved source: A source of fuel which has been found by the Executive Secretary, after such tests as he may require, to be in compliance with these regulations. 2. Existing: Things, such as equipment, machines, devices, articles, contrivances or installations which are in being at the time these regulations become effective except that any such existing equipment, machine, device, article, contrivance or installation which is altered, repaired or rebuilt at a cost of 30 percent or more of its replacement cost shall be reclassified as "new", as defined in this regulation. 3. Multiple chamber incinerator: Any article, machine, equipment, contrivance, structure or part of a structure, used to dispose of combustible refuse by burning, consisting of three or more refractory lined combustion furnaces in series, physically separated by refractory walls, interconnected by gas passage ports or ducts and employing adequate design parameters necessary for maximum combustion of the material to be burned, the refractories having a Pyrometric Cone Equivalent of 31, tested according to the method described in the American Society for Testing Materials, Method C-24-56. 4. New: Things, such as equipment, machines, devices, articles, contrivances or installations built or installed on or after the effective date of these regulations, and things or installations existing at said stated time which are later altered, repaired or rebuilt at a cost of 30 percent or more of their replacement cost. The cost of installing equipment designed solely for the purpose of air pollution control is not to be considered a cost of altering, repairing or rebuilding existing equipment for the purpose of this definition. 5. Open burning: The burning of any matter in such manner that the products of combustion resulting from the burning are emitted directly into the open atmosphere without passing through a stack, duct, or chimney. 6. Particulate matter: Any material, except uncombined water, which exists in a finely divided form as a liquid or solid at standard conditions. 7. Residual fuel oil: Fuel oil variously known as Bunker C, PS 400 and Number 6 as defined in ASTM D 396 487 (1959). 8. Process weight: The total weight of all materials introduced into a source operation, including solid fuels, but excluding liquids and gases used solely as fuels, and excluding air in troduced for purposes of combustion. 9. Refuse: Any combustible waste material containing carbon in a free or combined state, other than liquids or gases. 10. Salvage operation: Any business, trade, industry or other activity conducted in whole or in part for the purpose of salvaging or reclaiming any product or material such as metals or chemicals. 11. Smoke: Small gas-borne particles resulting from combustion, consisting of carbon, ash, and other material. 12. Source operation: The last operation preceding the emission of an air contaminant, which operation (a) results in the separation of the air contaminant from the process materials or in the conversion of the process materials into air contaminants, as in the case of combustion fuel; and (b) is not solely an air pollution abatement operation. 13. Standard conditions: A gas temperature of 60 degrees Fahrenheit and a gas pressure of 14.7 pounds per square inch absolute. 14. Trade waste: Solid, liquid or gaseous material resulting from construction or the prosecution of any business, trade or industry, or any demolition operation including, but not limited to, plastics, cardboard cartons, grease, oil, chemicals and cinders. 15. St. Louis Metropolitan Area: The geographical area comprised of St. Louis County, St. Charles County, Jefferson County, and the City of St. Louis. 16. ASTM: American Society for Testing and Materials, 1916 Race Street, Philadelphia, Pennsylvania. 17. Source gas volume: The volume of gas arising from a process or other source operation. 18. ASME: American Society of Mechanical Engineers, 345 East 47th Street, New York, New York. REGULATION II MAXIMUM ALLOWABLE EMISSION OF A. General Provisions 1. This regulation applies to installations in which fuel is burned for the primary purpose of producing steam, hot water, or hot air or other indirect heating of liquids, gases, or solids and, in the course of doing so, the products of combustion do not come into direct contact with process materials. Fuels include those such as coal, coke, lignite, coke breeze, fuel oil, and wood, but do not include refuse. When any products or by-products of a manufacturing process are burned for the same purpose or in conjunction with any fuel, the same maximum emission limitations shall apply. |
