PURPOSE: This rule provides for more restrictive emission limitations for an area in South St. Louis and St. Louis County which has been characterized by ambient levels of particulate and sulfur dioxide in excess of the national ambient air quality standards. The more restrictive limitations are for particulate matter and will affect the emissions from the by-product coke ovens at 526 East Catalan Street. The more restrictive fugitive particulate rule, however, will apply to all sources in the area identified in this rule.

Editor’s Note: The secretary of state has determined that the publication of this rule in its entirety would be unduly cumbersome or expensive. The entire text of the material referenced has been filed with the secretary of state. This material may be found at the Office of the Secretary of State or at the headquarters of the agency and is available to any interested person at a cost established by state law.

1. (1) Applicability. Except as otherwise provided, this rule shall apply to all sources in an area bounded as follows: Beginning at St. Louis County on the west bank of the Mississippi River approximately three thousand five hundred feet (3500') south of the confluence of the River des Peres and Mississippi River at the intersection of an extension of Rippa Street and the bank of the Mississippi River, west along Rippa Street to Broadway, north on Broadway to Vincent, west on Vincent to Gentry, northeast on Gentry to Orient, northwest on Orient to Lemay Ferry Road, northeast on Lemay Ferry Road to Bayless Avenue, northwest on Bayless Avenue to Interstate 55, northeasterly on Interstate 55 crossing the boundary between the City and County of St. Louis to Loughborough, then easterly on Loughborough to the west bank of the Mississippi River, to the point of beginning all lying within St. Louis City and St. Louis County.

2. (2) Restrictions Applicable to All Installations/Restriction of Emissions of Fugitive Particulate Matter.

   1. (A) No person may cause or permit the handling, transporting or storage of any material in a manner which allows particulate matter to become airborne in quantities and concentrations that—1) it remains visible in the ambient air beyond the premises where it originates or 2) its presence may be found beyond the premises where it originates and it is larger than forty (40) microns in size. The size of the particulate matter shall be determined by microscopy or any other technique proven to be equally accurate.
   2. (B) No person may cause or permit a building or its appurtenances, a road, a driveway, a parking lot or an open area to be constructed, used, repaired or demolished without applying all reasonable measures as may be required to prevent particulate matter from becoming airborne. The director may require a person owning, operating or otherwise in control of the building, appurtenance, road, driveway, parking lot or open area to take reasonable measures as may be necessary to prevent particulate matter from becoming airborne including, but not limited to, paving or frequent cleaning of roads, driveways and parking lots, application of dust-free surfaces, application of water and the planting and maintenance of vegetative ground cover or buffer zones.
   3. (C) No person may emit into the ambient air from any air contaminant source fugitive emissions greater than that which would be emitted after application of all reasonably available control technologies and all reasonable maintenance of plant and equipment.

3. (3) Restrictions Applicable to the By-Product Coke Ovens at 526 East Catalan Street.

   1. (A) The owner or operator shall control the visible emissions from the coke ovens so that—

      1. 1. The visible emissions from the coke

side hood shall not exceed ten percent (10%) opacity, as averaged from four (4) consecutive pushes. No instantaneous visible emission from the coke side hood shall exceed forty percent (40%) opacity at any time. Compliance shall be determined in accordance with procedures specified in 10 CSR 10-6.030(9). Opacity shall be read every fifteen (15) seconds for the duration of visible emissions escaping the coke side shed from four (4) consecutive pushes;

1. 2. No visible emissions shall occur dur-

ing charging of coke ovens except for a period of one hundred (100) seconds aggregated over six (6) consecutive charges. Compliance shall be determined in accordance with procedures specified in 10 CSR 10-6.030(15);

1. 3. No more than two percent (2%) of the

operating charging hole lids have any visible emissions;

1. 4. No more than five percent (5%) of

the operating offtakes having any visible emissions;

1. 5. No more than ten percent (10%) of

the operating pusher side coke oven door areas having any visible emissions;

1. 6. No more than five percent (5%) of

the operating coke side, coke oven door areas shall have any visible emissions at any one (1) time. Compliance shall be determined in accordance to procedures specified in 10 CSR 10-6.030(18), except that the observer shall walk under the hood outside the quench car rails; and

1. 7. The opacity from the battery stacks

not exceeding twenty percent (20%).

1. (B) The owner or operator shall install an air pollution control device for the emissions collected from the hoods. The particulate matter emissions from the air pollution control device shall be limited to .004 grains per standard cubic foot during the pushing operation and .002 grains per standard cubic foot when the pushing of coke is not occurring. If the requirements in paragraphs (3)(A)1.–7. of this rule are not met the control device shall be operated.
2. (C) The owner or operator shall control the coke pushing operation by modification of the existing hoods so they shall collect at least Specific to the St. Louis Metropolitan Area

ninety percent (90%) of the particulate matter generated during the pushing operation.

1. (4) Compliance Schedule Applicable to the By-Product Coke Ovens at 526 Catalan Street.
