|
Latest version.
|
|
The following additional definitions apply to R307-304: "Solvent cleaning" means operations performed using a liquid that contains any VOC, or combination of VOCs, which is used to clean parts, tools, machinery, equipment and work areas. Cleaning operations include, but are not limited to, spraying, wiping, flushing, and purging. Solvent cleaning does not include degreasing operations subject to R307-335. "Janitorial cleaning" means the cleaning of building floors, ceilings, walls, windows, doors, stairs, bathrooms, office surfaces and equipment. |
| R307-304-5. VOC Content Limits |
|
Latest version.
|
|
(1) No person shall use solvent products with a VOC content greater than the amounts specified in Table 1, unless the owner or operator uses an add-on control device as specified in R307-304-7 or the alternative method in R307-304-5(2). TABLE 1 Solvent Cleaning VOC Limits (excluding water and exempt solvents from the definition of volatile organic compounds found in R307-101-2) Solvent Cleaning Category VOC Limit (lb/gal) (g/L) Coatings, adhesives and ink manufacturing 4.2 500 Electronic parts and components 4.2 500 Medical devices and pharmaceutical Tools, equipment and machinery 6.7 800 General surface cleaning 5.0 600 Screening printing operations 4.2 500 Semiconductor tools, maintenance and equipment cleaning 6.7 800 Advanced composites manufacturing 6.7 800 Baby and child care diapers manufacturing 5.0 500 (2) As an alternative to the limits in Table 1 and for all general miscellaneous cleaning operations, a person may use a cleaning material with a VOC composite vapor pressure no greater than 8 mm Hg at 20 degrees Celsius. |
| R307-304-6. Work Practices |
|
Latest version.
|
|
An owner or operator shall store used applicators and shop towels in closed fireproof containers. |
| R307-304-7. Add-on Emission Control Systems Operations |
|
Latest version.
|
|
(1) If an add-on control system is used, the owner or operator shall install and maintain the add-on control system in accordance with the manufacturer recommendations and maintain an overall capture and control efficiency of at least 85%. The overall capture and control efficiency shall be determined using EPA approved methods, as follows: (a) The capture efficiency of a VOC emission control system's VOC collection device shall be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 CFR Part 51, Appendix M, Methods 204-204F, as applicable. (b) The control efficiency of a VOC emission control system's VOC control device shall be determined using test methods in Appendices A-1, A-6, and A-7 to 40 CFR Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable. (c) An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator. |
| R307-304-8. Recordkeeping |
|
Latest version.
|
|
(1) The owner or operator shall maintain records of the following: (a) The VOC content or composite vapor pressure of the solvent product applied and (b) If an add-on control device is used, key system parameters necessary to ensure compliance with R307-304-7. (i) Key system parameters must include, but are not limited to, temperature, pressure, flow rates, and an inspection schedule. (ii) Key inspection parameters must be in accordance with the manufacturer's recommendations, and as required to demonstrate operations are providing continuous emission reduction from the source during all periods that the operations cause emissions from the source. (2) All records shall be maintained for 2 years. (3) Records shall be made available to the director upon request. |
