(b) If a source meets the applicability requirements under subsection (a), but reduces its potential to emit for VOCs by means of federally enforceable operational restrictions (for example, production, hours of operation, or capacity utilization) to less than one hundred (100) tons per year by April 1, 2011, the source is not subject to the emission control requirements of SECTION 3 of this document.
(c) For purposes of subsection (a), an emission unit shall be considered regulated by a rule, section, or subpart if it is subject to the limits of that rule, section, or subpart.

At a minimum, the report shall include the following:
(i) The source ID.
(ii) The emissions unit identification.
(iii) The throughput of wastewater from calendar year.
The emission rates for the preceding calendar year shall be calculated in a manner consistent with the calendar year baseline emissions inventory.
(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.

(D) Measurements that are representative of the actual, normal wastewater generation rates.
(3) If the department or U.S. EPA determines that the VOC concentration cannot be adequately determined by knowledge of the wastewater, or by bench-scale or pilot-scale test data, the VOC concentration shall be determined in accordance with clause (C), or by a combination of the methods in clauses (A) through (C). VOC with a "Henry's Law Constant" less than 1.8 × 10-6 atm-m3/mole (0.1 y/x) at twenty-five (25) degrees Celsius shall not be included in the determination of VOC concentration. The VOC concentration of a wastewater stream shall be determined on the basis of a flow-weighted annual average by one (1) or more of the following methods:
(A) Knowledge of the wastewater. Sufficient information to document the VOC concentration. Examples of information include the following:
(i) Material balances.
(ii) Records of chemical purchases.
(iii) Previous test results.
(B) Bench-scale or pilot-scale test data. Sufficient information to demonstrate that the bench-scale or pilot-scale test concentration data are representative of the actual VOC concentration.
(C) Measurements. Collect a minimum of three (3) representative samples from the wastewater stream and determine the affected VOC concentration for each sample in accordance with SECTION 7 of this document (relating to approved test methods). The affected VOC concentration of the wastewater stream shall be the flow-weighted average of the individual samples.
(4) The annual affected VOC loading in wastewater for a wastewater stream shall be the annual average flow rate determined in subdivision (2) multiplied by the annual average affected VOC concentration determined in subdivision (3).
(5) The annual VOC loading in wastewater for a source shall be the sum of the annual VOC loading in wastewater for each affected VOC wastewater stream.
(6) The "Henry's Law Constant" shall be determined by the procedures in 40 CFR 60, Appendix J*, as proposed on December 9, 1998, in the Federal Register*.

SECTION 10. Maintenance wastewater requirements. Each owner or operator of a source subject to this document shall comply with the following requirements for maintenance wastewaters containing VOC:
(1) The owner or operator shall prepare a description of maintenance procedures for management of wastewaters generated from the emptying and purging of equipment in the process during temporary shutdowns for inspections, maintenance, and repair, such as a maintenance-turnaround, and during periods that are not shutdowns, such as routine maintenance. The descriptions shall specify the following:
(A) The process equipment or maintenance tasks that are anticipated to create wastewater during maintenance activities.
(B) The procedures that will be followed to properly manage the wastewater and control VOC emissions to the atmosphere.
(C) The procedures to be followed when clearing materials from the process equipment.
(2) The owner or operator shall modify and update the information required by subdivision (1) as needed following each maintenance procedure based on the actions taken and the wastewaters generated in the preceding maintenance procedure.
(3) The owner or operator shall maintain a record of the information required by this SECTION.
SECTION 11. Compliance. (a) Except where otherwise specified within this document, any owner or operator of a source that is subject to this document shall comply with the requirements of this document by no later than:
(1) April 1, 2011; or
(2) the date of initial startup of the waste management unit;
(b) For any emission control device that is used to comply with an emission control requirement of this document, the owner or operator shall demonstrate compliance by testing the emission control device in accordance with SECTION 7 of this document within ninety (90) days after the compliance date.
(c) For any treatment process (or combined treatment processes) that is used to comply with this document, the owner or operator shall demonstrate compliance by testing the treatment process (or combined treatment processes) in accordance with the methods in SECTION 7 of this document within ninety (90) days after the compliance date.
(d) Additional testing of the emission control device or the treatment process in accordance with SECTION 7 of this document may be required by the department to ensure continued compliance.
(e) In the event the owner or operator reduces the sources potential to emit under SECTION 1(b) of this document, the date on which the source subsequently meets the applicability criteria of SECTION 1(a) of this document is the date the source becomes subject to this document.
SECTION 12.
A variance request from the requirements of this document shall be made in accordance with IC 13-14-8-8.
SECTION 13. This document expires on the effective date of LSA [Document] #09-222 or ninety (90) days after filing with the publisher, whichever takes place first.
