PURPOSE: This rule specifies operating procedures, materials requirements, and control equipment specifications for the reduction of volatile organic compounds from aluminum foil rolling mills in the St. Louis ozone nonattainment area. Since volatile organic compounds are precursors to ozone formation, ambient ozone levels will be reduced.

1. (1) Applicability. This rule shall apply to all aluminum foil rolling facilities with potential volatile organic compound (VOC) emissions greater than or equal to one hundred (100) tons per year throughout St. Louis City and Jefferson, St. Charles, Franklin and St. Louis Counties.

2. (2) Definitions.

   1. (A) Cold rolling mill—Batch process aluminum sheet rolling mill with a preset gap between the work rolls used to reduce the sheet thickness. The process generally occurs at temperatures below two hundred sixty-five degrees Fahrenheit (265 °F.). A cold rolling mill is used mainly for the production of aluminum sheet at gauges between 0.3 inches to 0.002 inches. Reductions to finish gauge may occur in one (1) pass or several passes.
   2. (B) Intermediate foil mill—Batch process aluminum foil rolling mill with the work rolls in contact to reduce foil gauge. This process reduces finished sheet to intermediate foil gauges. An intermediate foil mill is used mainly in the production of aluminum foil at gauges between 0.010 inches to 0.0004 inches. Reductions to finish gauge may occur in several passes through the mill.
   3. (C) Finish foil mill—Batch process aluminum foil rolling mill with work rolls in contact to reduce foil gauge. This process reduces intermediate foil and in some cases finished sheet to final gauges. A finish foil mill is used mainly in the production of aluminum foil at gauges between 0.005 inches to 0.00018 inches. Reductions to finish gauge may occur in several passes through the mill. Specific to the St. Louis Metropolitan Area
   4. (D) Rolling lubricant—Petroleum based oil usually mixed with additives. The lubricant is used to cool the work rolls and provide lubrication for the product in contact with the work rolls.
   5. (E) Definitions of certain terms specified in this rule may be found in 10 CSR 10- 6.020.

3. (3) Emission Limits.

   1. (A) Rolling Lubricants.

      1. 1. Cold rolling mill.

         1. A. Rolling lubricants used on the cold

mill shall consist of low vapor pressure lubricants composed of saturated oils and additives. For purposes of this subparagraph, low vapor pressure shall be defined as less than 1.0 mmHg at one hundred degrees Fahrenheit (100 °F).

1. B. The initial boiling point of the as-

received oils shall be three hundred eighty degrees Fahrenheit (380 °F) or greater.

1. C. The initial boiling point of the as-

applied rolling lubricants shall be greater than three hundred eighty degrees Fahrenheit (380 °F).

1. D. The inlet or as-applied rolling

lubricant temperatures at each mill shall not exceed one hundred fifty-five degrees Fahrenheit (155 °F) and such temperatures shall be monitored at all times that the mill is in operation.

1. 2. Intermediate and finishing mills.

   1. A. Rolling lubricants used on the

intermediate and finish mills shall consist of low vapor pressure lubricants composed of saturated oils and additives. For purposes of this subparagraph, low vapor pressure shall be defined as less than 1.0 mmHg at one hundred degrees Fahrenheit (100 °F).

1. B. The initial boiling point of the as-

received oils shall be three hundred thirtyfive degrees Fahrenheit (335 °F) or greater.

1. C. The initial boiling point of the as-

applied rolling lubricants shall be greater than three hundred degrees Fahrenheit (300 °F).

1. D. The inlet or as-applied rolling

lubricant temperatures at each mill shall not exceed one hundred sixty degrees Fahrenheit (160 °F) and such temperatures shall be monitored at all times that the mill is in operation.

1. (B) Large Emission Sources.

   1. 1. For any rolling mill that has ever had

actual VOC emissions equal to or greater than one thousand (1,000) tons per calendar year—

1. A. Emissions capture methods and

emissions control equipment must be installed and used, which will result in an overall VOC emission reduction of at least eighty percent (80%).

1. B. An affected facility shall submit a

compliance plan that details how the required VOC emissions will be controlled. The compliance plan shall include:

1. (I) A physical description and the

operating characteristics of the rolling mill;

1. (II) A physical description of the

capture methods to be used and the operating characteristics and design specifications of the control equipment;

1. (III) Expected annual quantities of

material throughputs to the mill and the control equipment;

1. (IV) Potential VOC emissions,

expected actual VOC emissions from the mill, both controlled and uncontrolled, and total operating hours from the two (2) previous calendar years to be used as a baseline for determination of overall emissions reductions;

1. (V) Proposed methods of testing,

monitoring, record keeping and reporting for determining compliance with this rule;

1. (VI) A compliance schedule detail-

ing all important interim dates up to and including final compliance testing; and

1. (VII) Any additional information as

requested by the director.

1. C. The compliance plan shall be sub-

mitted to the director no later than sixty (60) days after the effective date of this rule.

1. D. The compliance plan shall be sub-

ject to the approval of the director.

1. 2. Contingency plans.

   1. A. Should an affected facility not be

able to meet the overall eighty percent (80%) VOC emission reduction, the facility must develop and submit a plan detailing corrective actions to obtain VOC emission reductions equivalent to the shortfall. The contingency plans shall be submitted to the director for approval.

1. B. The contingency plan shall include

the following:

1. (I) The total VOC emission reduc-

tions that will be achieved by the plan;

1. (II) The emission reduction method

of control that will be used to make up for any shortfall in the original compliance plan;

1. (III) Proposed method of record

keeping; and

1. (IV) A proposed implementation

schedule.

1. C. The contingency plan shall be sub-

mitted no later than one hundred twenty (120) days after a determination is made that the compliance plan does not meet the eighty percent (80%) emission reduction.

1. (4) Record Keeping.

   1. (A) For cold rolling mills—

      1. 1. Records of rolling lubricant formula- 10 CSR 10-5
