Control of particulate emissions from specific activities.
Tulsa Revised Ordinances tit. 17, § 710
in effectSection 710. - Control of particulate emissions from specific activities.
A. It is the purpose of this regulation to prevent undesirable ambient concentrations of particulate matter originating from specific industrial activities in the City of Tulsa.
B. General prohibition. No person owning, leasing or controlling the operation of any air contaminant source shall willfully, negligently or through failure to provide necessary equipment or facilities or through failure to take necessary precaution, permit the emission from the air contaminant source of such quantities of air contamination as will cause a condition of air pollution.
C. Emission of particulate matter from industrial processes.
1. General provisions.
a. This section applies to any operation, process or activity, except:
(1) The burning of fuel for indirect heating in which the products of combustion do not come directly into contact with process material;
(2) The burning of refuse; and
(3) The processing of salvageable refuse by burning.
b. The process weight per hour, referred to in this section, shall be based on the normal operation of maximum capacity of the equipment; and if such normal maximum capacity should be increased by process or equipment changes, the new normal maximum capacity shall be used as the process weight in determining the allowable emissions.
2. Emission limitations. No person shall cause, suffer, allow or permit the emission of particulate matter from any source in excess of:
a. The amount shown in Table 1 for the process weight allocated to such source; and
b. A concentration of thirty hundredths (0.30) grains per standard dry cubic foot of exhaust gases.
D. Emission of particulate matter from fuel burning equipment.
1. No person shall cause, suffer, allow or permit particulate matter caused by the combustion of fuel to be discharged from any stack or chimney into the atmosphere, in excess of the hourly rates set forth in the following Table I:
TABLE I
Heat Input Per Hour British Thermal Units | Maximum Allowable Emissions of Particulate Matter Pounds Per Million BTU
less than or equal to 10 | 0.60
100 | 0.35
1,000 | 0.20
10,000 and greater | 0.12 0.10 (CNTY)
Heat Input Per Hour Kilocalories | Maximum Allowable Emissions of Particulate Matter Grams Per Million
less than or equal to 2.52 | 1.08
2.52 | 0.63
252 | 0.34
2,520 | 0.18
2. For heat input between any two (2) consecutive heat inputs stated in the preceding table, maximum allowable emissions of particulate matter are shown in Table II below.
3. For the purposes hereof, heat input shall be calculated using the aggregate heat content of all fuels (using the upper limits of the range heating value) whose products of combustion pass through the stack or chimney.
4. When two (2) or more fuel burning units are connected to a single stack, the combined heat input of all units connected to the stack shall be used to determine the allowable emission from the stack.
5. When a single fuel burning unit is connected to two (2) or more stacks, the allowable emission from all the stacks combined shall not exceed that allowable for the same unit connected to a single stack.

3,500 | 1.75 | 5.96 | 100,000 | 50.00 | 44.6
4,000 | 2.00 | 6.52 | 120,000 | 60.00 | 46.3
5,000 | 2.50 | 7.58 | 140,000 | 70.00 | 47.8

10,000 | 5.00 | 12.0 | 6,000,000 | 3,000.00 | 92.7
Interpolation of the data in this table for process weight rates up to 60,000 lb/hr shall be accomplished by use of the equation:
E = 4.10 (p 0.67 )
and interpolation and extrapolation of the data for process weight rates in excess of 60,000 lb/hr shall be accomplished by use of the equation:
E = [55.0 (p 0.11 )] -40
where E = rate of emission in lb/hr and P = process weight rate in tons/hr.
