Determine the control device efficiency using Equation 4, and the test methods and procedures specified in Subparagraph (7)(c).3. If the permanent enclosure is demonstrated to be total, the value of N in Equation 5 is equal to 1.4. For owners or operators using a control system to comply with the provisions of this Rule, compliance is demonstrated if: (i) The installation of a permanent total enclosure is demonstrated (N=1); and(ii) The value of (R) calculated by Equation 6 in accordance with paragraph (7)(d) is greater than or equal to the value of R calculated by Equation 3 in accordance with Part (6)(a)2.(8) Recordkeeping Requirements (a) The owner or operator of an affected source subject to the emission limits in Paragraph (4) of this Rule shall maintain records of the following: 1. A list of each finishing material and strippable booth coating subject to the emission limits in Paragraph (4);2. The VOC and solids content, as applied, of each finishing material and strippable booth coating subject to the emission limits in Paragraph (4), and copies of data sheets documenting how the as applied values were determined.(b) The owner or operator of an affected source following the compliance procedures of paragraph (6)(c)2. shall maintain the records required by paragraph (8)(a) and records of the following: 1. Solvent and finishing material additions to the continuous coater reservoir; and2. Viscosity measurements.(c) The owner or operator of an affected source following the compliance method of paragraph (6)(a)2. shall maintain the following records: 1. Copies of the calculations to support the equivalency of using a control system, as well as the data that are necessary to support the calculation of E in Equation 3 and the calculation of R in Equation 6;2. Records of the daily average value of each continuously monitored parameter for each operating day. If all recorded values for a monitored parameter are within the range established during the initial performance test, the owner or operator may record that all values were within the range rather than calculating and recording an average for that day; and3. Records of the pressure drop across the catalyst bed for facilities complying with the emission limitations using a catalytic incinerator with a fluidized catalyst bed.(d) The owner or operator of an affected source subject to the work practice standards in Paragraph (5) of this Rule shall maintain onsite the work practice implementation plan and all records associated with fulfilling the requirements of that plan, including, but not limited to:1. Records demonstrating that the operator training program is in place;2. Records maintained in accordance with the inspection and maintenance plan;3. Records associated with the cleaning solvent accounting system;4. Records associated with the limitation on the use of conventional air spray guns showing total finishing material usage and the percentage of finishing materials applied with conventional air spray guns; and;5. Records showing the VOC content of solvent used for cleaning booth components, except for solvent used to clean conveyors, continuous coaters and their enclosures, and/or metal filters; and6. Copies of logs and other documentation developed to demonstrate that the other provisions of the work practice implementation plan are followed.(e) The owner or operator of an affected source shall maintain a copy of all other information submitted with the initial status report required by Subparagraph (9)(b).(f) The owner or operator of an affected source shall maintain all records for a minimum of 5 years.(g) Failure to maintain the records required by (a) through (f) of this Paragraph shall constitute a violation of the Rule for each day records are not maintained.(9) Reporting Requirements (a) The owner or operator of an affected source using a control system to fulfill the requirements of this Rule are subject to the following reporting requirements: 1. The owner or operator of an affected source subject to this Rule shall submit an initial compliance report by the compliance date. The report shall include the items required by Subparagraph (6)(b) of this Rule.2. The owner or operator of an affected source subject to this Rule and demonstrating compliance in accordance with Parts (6)(a)1. or 2. shall comply with Rule .03 of this chapter, except that the date for compliance for an existing source as of August 15, 1995 is November 15, 1996, and for each new source (after August 15, 1995) is within 180 days after the start-up of that source.(10) Special Provisions for Sources Using an Averaging Approach The owner or operator of an affected source complying with the emission limitations established in Paragraph (4) through the procedures established in (4)(a)4. shall also meet the provisions established in (a) through (i) of this Paragraph.
(a) Program goals and rationale. The owner or operator of the affected source shall provide a summary of the reasons why the affected source would like to comply with the emission limitations through the procedures established in (4)(a)4. and a summary of how averaging can be used to meet the emission limitations. The affected source shall also document that the additional environmental benefit requirement is being met through the use of the equations in (4)(a)4. These equations ensure that the affected source is achieving an additional 10 percent reduction in emissions when compared to affected sources using a compliant coatings approach to meet the requirements of the Rule.(b) Program scope. The owner or operator of the affected source shall describe the types of finishing materials that will be included in the affected source's averaging program. Stains, basecoats, washcoats, sealers, and topcoats may all be used in the averaging program. Finishing materials that are applied using continuous coaters may only be used in an averaging program if the affected source can determine the amount of finishing material used each day.(c) Program baseline. The baseline for each finishing material included in the averaging program shall be the lower of the actual or allowable emission rate as of the effective date of this rule, August 15, 1995. In no case shall the facility baseline emission rate be higher than what was presumed in the 1990 emissions inventory for the facility unless the State has accounted for the increase in emissions as growth.(d) Quantification procedures. The owner or operator of the affected source shall describe how emissions and changes in emissions will be quantified, including methods for quantifying usage of each finishing material. Quantification procedures for VOC content are included in Paragraph (7). The quantification methods used shall be accurate enough to ensure that the affected source's actual emissions are less than the allowable emissions, as calculated using Equation 1 or 2 in Part (4)(a)4., on a daily basis.(e) Monitoring, recordkeeping, and reporting. The owner or operator of an affected source shall provide a summary of the monitoring, recordkeeping, and reporting procedures that will be used to demonstrate daily compliance with the equations presented in (4)(a)4. The monitoring, recordkeeping, and reporting procedures shall be structured in such a way that inspectors and facility owners can determine an affected source's compliance status for any day.(f) Implementation schedule. The owner or operator of an affected source shall submit an averaging proposal for Technical Secretary and the Administrator's approval for each existing source as of 180 days after August 15, 1995, and for each new source (after August 15, 1995) which is within 180 days after the start-up of that source. This must ensure that all sources are in compliance with the State's Rule by the November 15, 1996. Submittal of the averaging proposal does not provide an exemption from this Rule. The source must submit the averaging proposal by a date that allows sufficient time for the Administrator's approval.Tenn. Comp. R. & Regs. 1200-03-18-.42
