252:100-23-1.  Purpose
As adopted in Oklahoma Register May 17, 1999 (16 Ok Reg 1368) effective June 1, 1999.

     The purpose of this Subchapter is to control emissions from cotton gins.


252:100-23-2.  Definitions
As adopted in Oklahoma Register May 17, 1999 (16 Ok Reg 1368) effective June 1, 1999.

     The following words and terms, when used in this Subchapter, shall have the following meaning, unless the context clearly indicates otherwise:
     "Cotton gin" means any facility that removes seed, lint, and trash from raw cotton and bales of lint cotton for further processing.  Each equipment exhaust, including the trash and burr hopper, located at a cotton gin shall be considered an individual process emission source.
     "Existing gin" means a gin which was in existence and had submitted  current emission inventories to the Division for the most recent two ginning seasons and was in possession of a valid annual renewable fee receipt prior to May 1, 1993.  All other gins shall be considered "new".
     "Gin site" means the land upon which a cotton gin is located and all contiguous land having common ownership or use.
     "High efficiency cyclone" means any cyclone type collector of the 2D-2D or 1D-3D configuration.  These designationsrefer to the ratio of cylinder to cone length, where D is the diameter of the cylinder portion.  A 2D-2D cyclone would exhibit a cylinder length of 2 x D and a cone length of 2 x D (90 percent collection efficiency for TSP).  A 1D-3D cyclone would exhibit a cylinder length of 1 X D and a cone length of 3 x D (95 percent collection efficiency for TSP).
     "High pressure exhausts" means the exhaust cotton handling air systems located at a cotton gin which are not defined as "low pressure exhausts".
     "Low pressure exhausts" means the exhaust air systems at a cotton gin which handle air from the cotton lint handling system and battery condenser.


252:100-23-3.  Applicability, general requirements
As adopted in Oklahoma Register May 17, 1999 (16 Ok Reg 1368) effective June 1, 1999.  An Emergency Adoption Oklahoma Register published May 15, 2000 (17 Ok Reg 1474) effective June 1, 2000, amended subsection 252:23-3(a) by changing “252:100-27" to “252:100-19-12” due to the revocation of OAC 252:100-27 and the moving of its substantive provisions to OAC 252:100-19-12 effective 06/01/2000.

Struck-out text NOT in SIP.

     (a)  Applicability.  Effective May 1, 1993, the provisions of this Subchapter are applicable to all new, modified, and existing cotton gins operating in the State of Oklahoma.  Cotton gins in compliance with this Subchapter are exempt from the requirements of 252:100-25, 252:100-19-12, and 252:100-29.

     (b)  General requirements.
          (1)  Permits required.  In addition to the requirements of this Subchapter, each new or modified cotton gin shall comply with the permitting requirements of 252:100-7.
          (2)  Air toxics emissions.  The requirements of this Subchapter are in addition to any which may be required under 252:100-41.
          (3)  Recordkeeping.  The owner or operator of a cotton gin shall maintain a log documenting the daily process weight and hours of operation.  Air emission control equipment replacement/repair costs shall also be recorded.  These records shall be maintained for a period of two years and shall be made available for inspection by DEQ personnel during normal business hours.
          (4)  Test methods.
               (A)  Visible emissions testing shall be conducted using EPA reference method 9 contained in 40 CFR Part 60, Appendix A.  Testing shall be performed by a Certified Visible Emissions Evaluator.
               (B)  Dispersion modeling for PM-10 shall be performed using an EPA approved modeling method.


252:100-23-4.  Visible emissions (opacity) and particulates
As adopted in Oklahoma Register May 17, 1999 (16 Ok Reg 1368) effective June 1, 1999.

     (a)  Opacity limit.  No person shall allow the discharge of any fumes, aerosol, mist, gas, smoke, vapor, particulate matter or any combination thereof exhibiting greater than 20% opacity.  This requirement shall not apply to visible emissions exhibiting greater than 20% opacity emitted during short-term occurrences, which consist of not more than one six-minute period in any consecutive 60 minutes, not to exceed three such periods in any consecutive 24 hours, during which the average of any six-minute period shall not exceed 60% opacity.

     (b)  Alternative opacity limit.  The 20% opacity limit as required under 252:100-23-4(a) may be increased for particulates only provided that the owner or operator demonstrates to the satisfaction of the Air Quality Council at public hearing that those requirements listed in 252:100-25-4(a) through (c) have been met.

     (c)  PM-10 emissions limit.  No cotton gin shall be operated so as to cause or contribute to a violation of the PM-10 ambient air quality standards or any other ambient air quality standard established in 252:100-3.


252:100-23-5.  Emission control equipment
As adopted in Oklahoma Register May 17, 1999 (16 Ok Reg 1368) effective June 1, 1999.

     (a)  Low pressure exhausts.  For emission control from low pressure exhausts, the use of screens with a mesh size of 70 by 70 or finer (U.S. Sieve), or the use of perforated condenser drums with holes not exceeding 0.045 inches in diameter or equipment of equivalent design efficiency as determined by the Executive Director shall be required.

     (b)  High pressure exhausts.  For emission control from high pressure exhausts, the use of 2D-2D cyclones shall be required for existing gins.  Existing gins shall install and use 1D-3D cyclone collectors or equivalent when the capital cost of repair or replacement of the existing 2D-2D cyclone exceeds 50% of the capital cost of a new 1D-3D cyclone.  New or modified cotton gins shall utilize a 1D-3D cyclone collector or equipment of equivalent collection efficiency upon commencement of operation.

     (c)  Burr hoppers.  For emission control during dumping, burr hoppers at existing gin sites located within the corporate city limits of any city or within 300 feet of two or more occupied establishments must be totally enclosed.  All new gin sites shall install and use a total enclosure on the burr hopper.


252:100-23-6.  Fugitive dust controls
As adopted in Oklahoma Register May 17, 1999 (16 Ok Reg 1368) effective June 1, 1999.

     (a)  For control of fugitive dust, no person shall allow the handling, transporting, or disposition of any substance or material that is likely to be scattered by the air or wind, and no person shall operate or maintain any gin site, open area, right-of-way, storage pile or materials, vehicle, or construction, or any other enterprise which involves any material or substance likely to be scattered by the wind or air, that would be classified as air pollution without taking reasonable precautions to minimize atmospheric pollution.

     (b)  No person shall allow the discharge of any visible fugitive dust emissions beyond the property line on which the emissions originate.


252:100-23-7.  Permit by rule
As adopted in Oklahoma Register May 17, 1999 (16 Ok Reg 1368) effective June 1, 1999.

     (a)  Applicability.  Any new or existing facility may be constructed or operated under this section if it meets the requirements of 252:100-7-60(a), (b), and (c) and has the Standard Industrial Classification (SIC) code 0724 Cotton Ginning.

     (b)  Requirements.
          (1)  In addition to the requirements in 252:100-7-60(a), (b), and (c), an owner or operator of a facility subject to this section shall comply with all of the requirements of this Subchapter.
          (2)  Maximum production rate of a facility subject to this section shall be 36,000 bales per year.
