Sec. 5. Alternate methods of demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria in this rule may be used if approved by U.S. EPA. The approval shall occur when the department is informed, in writing, that U.S. EPA has no objections to the alternate method or methods of control. The alternate methods of control are as follows:

1. (1) Ninety percent (90%) overall control option. As an alternative to the control requirements of section 4 of this rule, the owner or operator of waste management units may elect to ensure that the overall control of VOC emissions at the source from wastewater from affected source industries is at least ninety percent (90%) less than the calendar year baseline emissions inventory for VOC emissions to the ambient air from process wastewater, provided that adequate documentation is submitted that supports the accuracy of the calendar year baseline emission inventory and the following requirements are met:

   1. (A) To qualify for the control option available under this subdivision after the effective date of this rule, the owner or operator of a waste management unit for which a control plan was not previously submitted shall submit a control plan to the department that demonstrates that the overall control of VOC emissions at the source from wastewater from affected industrial categories will be at least ninety percent (90%) less than the calendar year baseline emissions inventory. Any control plan submitted after the effective date of this rule must be approved by U.S. EPA in writing before the owner or operator may use the control option available under this subdivision for compliance. At a minimum, the control plan shall include the following:

      1. (i) The applicable emissions unit identification.
      2. (ii) The source ID.
      3. (iii) The calendar year baseline emission rates of VOC from wastewater from applicable industrial categories (consistent with the calendar year baseline emissions inventory).
      4. (iv) A plot plan showing the location, the emissions unit identification, and ID associated with a waste management unit.
      5. (v) The VOC emission rates for the preceding calendar year.
      6. (vi) An explanation of the record keeping procedure and calculations that will be used to demonstrate compliance.
   2. The VOC emission rates shall be calculated in a manner consistent with the calendar year baseline emissions inventory.

   3. (B) The owner or operator shall submit an annual report no later than March 31 of each year to the department that demonstrates that the overall control of VOC emissions at the account from wastewater from affected industrial categories during the preceding calendar year is at least ninety percent (90%) less than the baseline emissions inventory. At a minimum, the report shall include the following:

      1. (i) The source ID.
      2. (ii) The emissions unit identification.
      3. (iii) The throughput of wastewater from calendar year.
   4. The emission rates for the preceding calendar year shall be calculated in a manner consistent with the calendar year baseline emissions inventory.
   5. (C) All representations in control plans and annual reports become enforceable conditions. No variation from such representations is allowed if the variation will cause a change in the identity of the specific emission sources being controlled or the method of control of emissions unless the owner or operator submits a revised control plan to the department not later than thirty (30) days after the change. All control plans and reports shall include documentation that the overall reduction of VOC emissions at the account from wastewater from affected source categories continues to be at least ninety percent (90%) less than the calendar year baseline emissions inventory. The emission rates shall be calculated in a manner consistent with the calendar year baseline emissions inventory.
   6. (D) For waste management units, the calendar year baseline is 2002.

2. (2) The owner or operator of an affected industrial category may elect to comply with the provisions of 40 CFR 63, Subpart G* (National Emission Standards for Hazardous Air Pollutants From the Synthetic Organic Chemical Manufacturing Industry for Process Vents, Storage Vessels, Transfer Operations, and Wastewater), 40 CFR 63, Subpart JJJ* (National Emission Standards for Hazardous Air Pollutants: Group IV Polymers and Resins), 40 CFR 63, Subpart FFFF* (National Emission Standards for Hazardous Air Pollutants: Miscellaneous Organic Chemical Manufacturing), or any other emission standard promulgated under 40 CFR 63 that references the wastewater control requirements set forth in 40 CFR 63, Subpart G* if the wastewater stream is subject to the national emission standards for hazardous air pollutants control requirements for that category, as alternatives to complying with this rule, provided the following:

   1. (A) The term "affected VOC" is substituted each place that 40 CFR 63, Subpart G*, 40 CFR 63, Subpart JJJ*, 40 CFR 63, Subpart FFFF*, and any other 40 CFR 63 emission standard references the term "organic hazardous air pollutant" or "organic HAP".

   2. (B) For affected VOC not specifically listed in table 9 of 40 CFR 63, Subpart G*, the corresponding fraction removed (Fr) value shall be determined using one (1) of the following methods:

      1. (i) Determine the Fr value by the procedures in 40 CFR 60, Appendix J*, as proposed on December 9, 1998, in the Federal Register.
      2. (ii) Assign an Fr value of 0.99.
      3. (iii) Use WATER9, a wastewater treatment model of U.S. EPA, to determine the Fr value of a chemical.
   3. (C) Before implementing the option available under this subdivision, the owner or operator provides written notice to the department of their intent to use this option.
