(a) Sulfuric acid plants.
(1) Emission limit.
(A) A person operating a new sulfuric acid plant shall not cause, suffer, or allow the discharge into the atmosphere of:
(i) sulfur dioxide in the effluent in excess of four (4) pounds per ton of 100 percent sulfuric acid produced (2 kg per metric ton), maximum two-hour average;
(ii) sulfuric acid mist which is in excess of 0.15 pound per ton of 100 percent sulfuric acid produced (75 grams per metric ton), maximum two-hour average, expressed in H2SO4; or
(iii) a visible emission equivalent to an opacity of five (5) percent.
(B) These emission limits shall apply to only those sulfuric acid plants producing sulfuric acid by the contact process by burning elemental sulfur, alkylation acid, hydrogen sulfide, organic sulfides and mercaptans or acid sludge.
(2) Emission monitoring.
(A) All sulfuric acid plants regulated under this subsection shall have installed, calibrated, maintained and operated, an instrument for continuously monitoring and recording emissions of sulfur dioxide. The instrument installed and used pursuant to this subsection shall be calibrated following the Oklahoma test procedure requirements using the performance specifications 2 and 3 of 40 CFR Part 60, Appendix B.
(B) The owner or operator of any sulfuric acid plant subject to provisions of this paragraph shall maintain a file of all measurements required including compliance status records and excess emissions measurements. These records and measurements shall be retained for at least two years following the date of such measurement, and made available for inspection by the Air Quality Division or it's representative during normal business hours.
(b) Fuel-burning equipment.
(1) Emission limit.
(A) No person shall cause, suffer or allow the discharge into the atmosphere of sulfur oxides measured as sulfur dioxide from new gas fuel-burning equipment in excess of 0.2 pound per million BTU heat input (0.36 gram per million gram-calories), maximum three-hour average.
(B) No person shall cause, suffer or allow the discharge into the atmosphere of sulfur oxides measured as sulfur dioxide from new liquid fuel-burning equipment in excess of 0.8 pound per million BTU heat input (l.4 grams per million gram-calories), maximum three-hour average.
(C) No person shall cause, suffer or allow the discharge into the atmosphere of sulfur oxides measured as sulfur dioxide from new solid fuel-burning equipment in excess of 1.2 pounds per million BTU heat input (2.20 grams per million gram-calories), maximum three-hour average.
(D) If a solid fuel sampling and analysis method is used to determine emission compliance, averaging time will be determined on a 24 hour basis.
(E) Where different fuels are burned simultaneously in any combination, the applicable standard shall be determined by proration unless a secondary fuel is used in de minimis quantities (less than 5% of total BTU input annually). Compliance shall be determined using the formula (effective July 1, 1972),
(y(.80) + z(1.2)) / y + z
where y is the percent of total heat input derived from liquid fuel and z is the percent of total heat input derived from solid fuel.
(2) Emission and fuel monitoring.
(A) There shall be installed, calibrated, maintained, and operated, in any new fuel-burning equipment with a rated heat input of 250 million BTU/hr. or more emission monitoring instruments as follows:
(i) a photoelectric or other type smoke detector and recorder, except where gaseous fuel is the only fuel burned; and,
(ii) an instrument for continuously monitoring and recording sulfur dioxide emissions, except where gaseous fuel containing less than 0.1 percent sulfur is the only fuel burned or a solid fuel sampling and analysis method is used to determine emission compliance.
(B) Instruments installed and used for monitoring shall be calibrated following performance specifications 2 and 3 of 40 CFR Part 60, Appendix B.
(C) The sulfur content of solid fuels as burned shall be determined in accordance with previous methods as approved by the Executive Director or in accordance with Method 19 of 40 CFR Part 60, Appendix A.
(D) The owner or operator of any fuel-burning equipment with a rated heat input of 250 million BTU/hr. or over shall maintain a file of all measurements required in subparagraphs (A), (B), or (C) of this paragraph, including compliance status records and excess emissions measurements. These records and measurements shall be retained for at least two (2) years following the date of such measurements, and made available for inspection by the Air Quality Division or its representatives during normal business hours.
(c) Gas sweetening and sulfur recovery plants.
(1) Natural gas processing.
(A) As specified in 252:100-31-26(a)(1)(B), a new gas sweetening plant is allowed direct oxidation of hydrogen sulfide to sulfur dioxide without a prior sulfur removal step when the exhaust gas contains no more than 100 pounds per hour of sulfur dioxide. When the sulfur content of an acid-gas stream from a new gas sweetening unit is greater than this allowed emission but less than or equal to 5.0 long tons per day (LT/D) of sulfur, a sulfur dioxide emission reduction efficiency of at least 75.0 percent shall be achieved by means of a sulfur recovery facility prior to the discharge of gases from the system.
(B) When the sulfur content of an acid-gas stream from a new gas sweetening unit is greater than 5.0 LT/D but less than or equal to 150 LT/D, a sulfur dioxide emission reduction efficiency shall be achieved by means of a sulfur recovery facility such that
Z = 92.34 (X0.00774)
where Z is the minimum emission reduction efficiency required at all times and X is the sulfur feed rate, i.e., the hydrogen sulfide in the acid gas from the sweetening unit, expressed as long tons per day of sulfur rounded to one decimal place.
(C) When the sulfur content of an acid-gas stream from a new gas sweetening unit is greater than 150 LT/D but less than or equal to 1500 LT/D, a sulfur dioxide emission reduction efficiency shall be achieved by means of a sulfur recovery facility such that
Z = 88.78 (X0.0156)
where Z and X are defined as in (B) of this subsection.
(D) When the sulfur content of an acid-gas stream from a new gas sweetening unit is greater than 1500 LT/D, a minimum sulfur dioxide reduction efficiency of 99.5 percent shall be required.
(2) Other processes. The emission of sulfur oxides, calculated as sulfur dioxide, from a new sulfur recovery plant operating in conjunction with other processes is limited to rates consistent with the emission reduction efficiencies calculated based on equivalent sulfur feed rate in long tons per day (LT/D) in the same manner as for natural gas processing in (c)(1) of this section.
(3) Emission monitoring. For facilities regulated under this subsection emission monitoring may be required as determined by the Executive Director in accordance with Subchapter 45 of this Chapter.
(d) Nonferrous smelters.
(1) Emission limit. The emission of sulfur oxides, calculated as sulfur dioxide, from new nonferrous smelters is restricted according to the following equations as a maximum two-hour average, where X equals total sulfur fed to smelter (lb/hr) and Y equals sulfur dioxide emissions (lb/hr).:
(A) Copper Smelters: Y = 0.2 (X)
(B) Zinc Smelters: Y = 0.564 (X0.85)
(C) Lead Smelters: Y = 0.98 (X0.77)
(2) Emission monitoring.
(A) All new nonferrous smelters regulated under this subsection shall have installed, calibrated, maintained and operated an instrument for continuously monitoring and recording emissions of sulfur dioxide following performance specifications 2 and 3 of 40 CFR Part 60, Appendix B and following the quality assurance procedure in 40 CFR Part 60, Appendix F.
(B) The owner or operator of any new nonferrous smelter subject to provisions of this subparagraph shall maintain a file of all measurements required, including compliance status records and excess emissions measurements. These records and measurements shall be retained for at least two years following the date of such measurements, and made available for inspection by the Air Quality Division or its representative during normal business hours.
(e) Paper pulp mill.
(1) Emission limit. The emission of sulfur oxides, calculated as sulfur dioxide, from the blow pits, washer vents, storage tanks, digester relief, and recovery furnace of any new paper pulp mill shall not exceed eighteen pounds per air-dried ton of pulp produced, maximum two-hour average.
(2) Emission monitoring.
(A) All new paper pulp mills shall have installed, calibrated, maintained and operated instruments for continuously monitoring and recording emissions of sulfur dioxide from the recovery system gas-cleaning equipment and other locations as required by the Executive Director. The instruments installed and used pursuant to this Section shall have a confidence level of at least 95 percent and be accurate within +20 percent and shall be calibrated following performance specifications 2 and 3 of 40 CFR Part 60, Appendix B and following the quality assurance procedure in 40 CFR Part 60, Appendix F.
(B) The owner or operator of any new paper pulp mill subject to provisions of this subparagraph shall maintain files of all measurements required, including compliance status records and excess emissions measurements. These records and measurements shall be retained for at least two years following the date of such measurements, and made available for inspection by the Air Quality Division or its representative during normal business hours.
252:100-31-26. Hydrogen sulfide
As adopted in Oklahoma Register May 16, 1994 (11 Ok Reg 2031) effective May 26, 1994.
Approved by EPA November 3, 1999 (64 FR 59629) effective January 3, 2000 (OKc48).
(a) Petroleum and natural gas processes.
(1) Emission limit.
(A) No person shall cause, suffer, or allow the discharge into the atmosphere of hydrogen sulfide from any new petroleum or natural gas process equipment without removal of the hydrogen sulfide from the exhaust gas or oxidizing it to sulfur dioxide in a system which insures at all times complete combustion of the hydrogen sulfide, with the exhaust gas then being emitted from a stack at least 50 feet in height. Efficiency of these removal or oxidation systems shall not allow to be emitted more than 0.3 pound per hour of hydrogen sulfide as a two-hour maximum, with a maximum efficiency required of 95 percent of the hydrogen sulfide in the exhaust gas. This subparagraph does not apply to pipeline quality sweetened gas.
(B) Direct oxidation of hydrogen sulfide to sulfur oxides without a prior removal step meeting emission limits of 252:100-31-25(c)(1) is not allowed for any system which would allow discharge of more than 100 pounds per hour of sulfur oxides expressed as sulfur dioxide, maximum two-hour average.
(2) Emission monitoring.
(A) All new petroleum and natural gas processing facilities regulated under this subsection shall have installed, calibrated, maintained and operated an alarm system which will signal noncombustion of the gas.
(B) All new petroleum and natural gas processing facilities regulated under this Section shall demonstrate compliance with the ambient air limits of 252:100-31-12(a) using either dispersion modeling or ambient air measurements.
(b) Other processes.
(1) Standard. No person shall cause, let, suffer, or allow any emission of hydrogen sulfide from any source which results in an ambient air concentration of hydrogen sulfide at any given point of 0.1 ppm for a one-hour period. This standard shall not apply to ambient air concentrations occurring on the property from which such emission occurs, providing such property, from the emission point to the point of any such concentration is controlled by the person responsible for such emission.
(2) Determination of violation. Violations of this Section may be determined by the Executive Director by use of appropriate material balances and/or emission factors, and on the basis of the ambient air concentration, or use of appropriate atmospheric dispersion models approved by EPA. Determinations made by the Executive Director using these procedures indicating that the limits set in 252:100-31-26(b)(1) have been exceeded shall constitute prime evidence that the standard has been violated. Source operators may use these procedures in lieu of ambient air monitoring as proof of compliance with limits set in 252:100-31-26(b)(1).
