SAN FRANCISCO BAY AREA, CALIFORNIA REGULATION 2 (revised 1962) Division 5, Chapter 1 Sec. 5111.1 No person shall cause, let, permit, suffer, or allow any emission from any heat transfer operation which does not comply with the visible emission limitations in Section 3110, Chapter 1, Division 3, except as provided in Section 5111.3. Sec. 5111.2 No person shall cause, let, permit, suffer, or allow the emission from any heat transfer operation of particles in sufficient mumber to cause annoyance to any other person, which particles are sufficiently large as to be visible as individual particles at the emission point or of such size and nature as to be visible individually as incandescent particles. This section 5111.2 shall only apply if such particles fall on real property other than that of the person responsible for the emission. Sec. 5111.3 The limitations of Section 5111.1 shall not apply to emissions resulting from soot-blowing on any oil-fired heat transfer operation, provided such emissions are not equal to or greater than Ringelmann No. 3 or an equivalent obscuration within the meaning of Sections 3110.1 and 3110.2; and provided further that the aggregate duration of such emissions during any twenty-four hour period does not exceed 6.0 minutes per billion Btu gross heating value of oil fuel burned during such twenty-four hours; and provided further that such operation uses fuel at a rate not less than 140 million Btu per hour. Sec. 5112 PARTICULATE MATTER. No person shall cause, let, permit, suffer, or allow any emission from a heat transfer operation of particulate matter in excess of 0.30 grains per standard dry cubic foot of exhaust gas. For the purposes of this section 5112, the actual concentration measured shall be corrected to a concentration which the same quantity of particulate matter would constitute in the exhaust gas minus water vapor, corrected to standard conditions and containing 6% oxygen by volume. Calculation of this corrected concentration from the actual measured concentration shall follow the procedure given in Chapter 1, Division 8. Tests to determine compliance with this section 5112 shall be for not less than 50 minutes in any consecutive 60 minutes, or 90% of the time of actual source operation, whichever is less. REGULATIONS PERTAINING TO PARTICULATE EMISSIONS FROM REFUSE-BURNING EQUIPMENT (Additional types of regulations are listed in the zoning ordinances of Porter County, Indiana and DuPage County, Illinois in the "Zoning Ordinances" section of this compilation) (a) Incinerators shall completely consume not less than 95 percent of all combustible material charged into them, except that domestic gas-fired incinerators shall meet the standards given in the American Standards Association publication Z-21.61957, or latest revision thereof. (b) Smoke emitted into the atmosphere from any incinerator shall be of an appearance, density, or shade lighter than No. 1 of the Ringelmann Chart. (c) No person shall cause, suffer, or allow to be emitted into the atmosphere from any incinerator or pass a convenient measuring point near the stack outlet, fly ash in the gases to exceed 0.20 lb. per 1,000 lb. of gases. CITY OF CINCINNATI, OHIO AIR POLLUTION CONTROL ORDINANCE NO. 119-1965 (passed March 24, 1965) Division J. INCINERATORS Sec. 2509-8. INCINERATOR MAINTENANCE AND OPERATION. It shall be unlawful for any person to permit or cause foul or offensive odors, fumes, gases, fly ash or smoke in the maintenance or operation of an incinerator. Odors shall be considered offensive when any odor similar to that of burning paper, garbage, or other cellulose material is emitted from the incinerator chimney and is detectable at a distance of more than 25 feet from the incinerator chimney or at a location of a citizen complaint whichever is a greater distance. Exception: One period of not to exceed ten (10) minutes in any consecutive 24 hour period will be permitted for the purpose of bringing the incinerator up to the required discharge gas temperature. Fly ash shall be considered offensive when the particulate matter in the combustion gases discharged from the chimney or at any convenient measuring point in the chimney or in the chimney connection from the incinerator to the chimney exceeds either criteria A or criteria B of this section. Criteria A: .4 pounds of particulate matter per 1000 pounds of discharged gases adjusted to 12 per cent CO2. Criteria B: A discharge from the incinerator chimney of 500,000 particles per minute for incinerators located in residence districts; 750,000 particles per minute for incinerators located in business districts; and 1,000,000 particles per minute for incinerators located in industrial districts. The method of determining criteria A shall be by approved stack testing procedure. The method of determining criteria B, the number of particles discharged from the incinerator chimney, shall be the "adhesive surface method" and the procedure shall be as follows: Two-inch white strips of approved adhesive material shall be wrapped around a suitable holder approximately 2 3/4 inch in diameter and inserted in the discharge |
