SUBCHAPTER 33.  CONTROL OF EMISSION OF NITROGEN OXIDES
Aa approved by EPA December 29, 2008 (73 FR 79400) effective February 27, 2009 (OKd06).

Sections:
252:100-33-1.    Purpose, OKc48
252:100-33-1.1.  Definitions, OKd06
252:100-33-1.2.  Applicability, OKd06
252:100-33-2.    Emission limits, OKd06


252:100-33-1.  Purpose
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).

     The purpose of this Subchapter is to control the emission of nitrogen oxides from stationary sources to prevent the Oklahoma air quality standards from being exceeded and insure that the present level of air quality in Oklahoma is not degraded.


252:100-33-1.1.  Definitions
As adopted in Oklahoma Register May 15, 2001 (18 Ok Reg 1492) effective June 1, 2001.
Approved by EPA December 29, 2008 (73 FR 79400) effective February 27, 2009 (OKd06).

     The following terms, when used in this Subchapter, shall have the following meaning, unless the context clearly indicates otherwise:
     "New fuel-burning equipment" means any fuel-burning equipment, with the exception of gas turbines, that was not in being on February 14, 1972, or any existing fuel-burning equipment that was altered, replaced, or rebuilt after February 14, 1972, resulting in an increase in nitrogen oxide emissions, and any gas turbine that was not in being on July 1, 1977, or any existing gas turbine that was altered, replaced, or rebuilt after July 1, 1977, resulting in an increase in nitrogen oxide emissions.
     "Three-hour average" means the arithmetic average of sampling results or continuous emission monitoring data from three contiguous one-hour periods.


252:100-33-1.2.  Applicability
As adopted in Oklahoma Register May 15, 2001 (18 Ok Reg 1492) effective June 1, 2001.
Approved by EPA December 29, 2008 (73 FR 79400) effective February 27, 2009 (OKd06).

     This Subchapter applies to new fuel-burning equipment that meets both of the following criteria.
          (1)  The fuel-burning equipment has a rated heat input of 50 million (MM) Btu/hr or greater.
          (2)  The equipment burns solid fossil, gas, or liquid fuel.


252:100-33-2.  Emission limits
As adopted in Oklahoma Register May 15, 2001 (18 Ok Reg 1492) effective June 1, 2001.
Approved by EPA December 29, 2008 (73 FR 79400) effective February 27, 2009 (OKd06).


     (a)  Gas-fired fuel-burning equipment.  Nitrogen oxide emissions (calculated as nitrogen dioxide) from any new gas-fired fuel-burning equipment shall not exceed 0.20 lb/MMBtu (86 ng/J) heat input, three-hour average.

     (b)  Liquid-fired fuel-burning equipment.  Nitrogen oxide emissions (calculated as nitrogen dioxide) from any new liquid-fired fuel-burning equipment shall not exceed 0.30 lb/MMBtu (129 ng/J) heat input, three-hour average.

     (c)  Solid fossil fuel-burning equipment.  Nitrogen oxide emissions (calculated as nitrogen dioxide) from any new solid fossil fuel-burning equipment shall not exceed 0.70 lb/MMBtu (300 ng/J) heat input, three-hour average.
