§ 4-11 FUGITIVE AIR CONTAMINANT EMISSIONS.

   No person shall cause or permit the emission of any fugitive air contaminant into the outdoor atmosphere from any air contaminant source whatsoever, including but not limited to vehicular movement, transportation of materials, construction, alteration, demolition, or wrecking, or commercially or industrially related activities such as loading, unloading, storing or handling of materials, without taking reasonable precautions to prevent such emission. Whenever any fugitive air contaminant escapes from a building or equipment in such manner and amount as to cause a nuisance or to violate § 4-9 or any other provisions of this ordinance, the Director may order that the building or equipment in which a processing, handling and storage are done be tightly closed and ventilated in such a way that the air contaminant leaving the building or equipment is treated by abatement process before discharge into the outdoor atmosphere.

(Ord. 2494, passed 5-12-1975)

§ 4-12 OBJECTIONABLE ODOR PROHIBITED.

   No person shall cause, allow or permit the discharge of air contaminant which cause or contribute to objectionable odor.

(Ord. 2494, passed 5-12-1975)

§ 4-13 OPEN BURNING.

   (a)   No person shall dispose of refuse or other waste materials by open burning, or cause or permit open burning of refuse or other waste materials except where permitted.

   (b)   No person shall maintain an open fire except as follows.

      (1)   Fire for noncommercial cooking of food for human consumption. Such fire shall be fueled by charcoal or propane gas only.

      (2)   Fire for training personnel in methods of fire fighting upon notification by writing to the Director.

      (3)   Fires for other essential purposes for which written approval has been granted by the Director.

   (c)   Violation of this section shall be a municipal civil infraction punishable by a fine pursuant to §§ 1-10 through 1-21.

§ 4-14 EMISSION OF PARTICULATE MATTERS.

   It is unlawful for any person to cause or allow the emission of particulate matter from any air contaminant source in excess of:

   (a)   The maximum allowable emission rate listed in Table I.

   (b)   The maximum allowable emission rate specified as a condition of a permit to install and certificate of operation.

   (c)   The maximum allowable emission rate as determined by Table II below for sources not covered in subsections (a) and (b).

Table I Particulate Matter Emission Schedule
Source		Maximum Allowable Emission at Operation Conditions(a) (Pounds Particulate per 1,000 Pounds Gas)
A.   Fuel burning equipment	Capacity Rating in Pounds Steam per Hour
1.   Pulverized coal (includes cyclone furnaces)	0 – 1,000,000	See Figure 1* for maximum emission limit

Note: It is required that a maximum allowable emission listing be applied for to the Director for any kiln installation which will result in a total plant kiln capacity in excess of 15,000 barrels of cement per day.
H.   Iron ore pelletizing	Gas Flow Rate (SCFM)

Footnotes    (a)   Fuel burning and refuse incineration limitations shall be calculated at 50% excess air.    (b)   Emission limitations for specific ratings are determined by linear interpolation between the ranges shown.    (c)   These emission limitations do not apply to domestic incinerators (defined as having not over 5 cubic feet of storage capacity.)    (d)   Afterburner or approved equivalent is mandatory.    (e)   Differentiation between jobbing and production foundries:       Cupolas used in a jobbing foundry are the same as those used in a production foundry and will vary in size only according to the quantity of iron melted per hour. However, the cupolas in a jobbing foundry will be run intermittently for just long enough at one time to pour the molds that are ready on the foundry floor, job by job. This might be for a two to four-hour period per day for any number of days per week.       Production foundry cupolas will melt continuously to pour a succession of molds that are constantly being prepared to receive this continuous flow of iron. This could become 8 hours, 16 hours or 24 hours per day for any number of days per week. *Editor’s note: Figure 1 is not set out herein, but is on file and available for inspection in the office of the City Clerk.

Footnotes    (a)   Interpolation of the data in this table for process weight rates up to 60,000 lbs/hr shall be accomplished by use of the equation:    E = 4.10P0.67 and interpolation and extrapolation of the data for process weight rates in excess of 60,000 lbs/hr shall be accomplished by use of the equation E = 55.0P0.11 - 40, where E = rate of emission in lbs/hr and P = process weight in tons/hr.    Process weight — The total amount of all material introduced into a source operation, including solid fuels, but excluding liquid fuels and gaseous fuels when these are used as fuels and air introduced for purposes of combustion.    Process weight rate — For continuous or long-term operations: The total process weight for the entire period of operation or for a typical portion thereof, divided by the number of hours of such period or portion thereof.    For batch operations: The total process weight for a period which covers a complete operation or an integral number of cycles, divided by the hours of actual process operation during the period.

§ 4-15 AIR CONTAMINANT OR WATER VAPOR, WHEN PROHIBITED.

   No person shall cause or permit the emission of an air contaminant or water vapor including an air contaminant whose emission is not otherwise prohibited by this ordinance, or an air contaminant or water vapor which reacts or may react with any other air contaminant or natural air, and which causes or will cause detriment to the safety, health, welfare or comfort of any person or which causes or will cause damage to property or business.

(Ord. 2494, passed 5-12-1975)

§ 4-16 DILUTING AND CONCEALING EMISSIONS.

   Unless prior written approval is obtained from the Director, no person shall build, erect, install or use any article, machine, equipment or other contrivance, the sole purpose of which is to dilute or conceal an emission without resulting in a reduction in the total release of air contaminants to the outdoor atmosphere. This section does not apply to the control of odors.

(Ord. 2494, passed 5-12-1975)

§ 4-17 MALFUNCTION OF EQUIPMENT; SCHEDULED MAINTENANCE; REPORTING.

   (a)   In the case of shutdown of control equipment for necessary scheduled maintenance unaccompanied by shutdown of the air contaminant source, the intent to shutdown such equipment shall be reported to the Director at least 24 hours prior to the planned shutdown. This prior notice shall include, but is not limited to the following:

      (1)   Identification and location of the specific control equipment to be taken out of service;

      (2)   The expected length of time that the control equipment will be out of service;

      (3)   The nature and quantity of emissions of air contaminants likely to occur during the shutdown;

      (4)   Description of the maintenance of the control equipment.

   (b)   In the event that any air contaminant source, control equipment or related facility breaks down in such a manner as to cause the emission of air contaminants in violation of this ordinance, the person responsible for such equipment shall immediately notify the Director of such failure or breakdown, and provide a written statement giving all pertinent facts, including the expected duration of the break. The Director shall be notified when the condition causing the failure or breakdown has been corrected and the equipment is again in operation.
