Section 326 IAC 8-17-4 - VOC emissions control requirementsAuthority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-15; IC 13-17
Sec. 4.
(a) The owner or operator of a source that is subject to this rule shall not use a solvent to perform solvent cleaning operations unless the solvent complies with the applicable VOC content limitation as follows: | Solvent Cleaning Operation | VOC Limit (as-applied) (pounds/gallon) |
| Product cleaning during manufacturing process or surface preparation for coating, adhesive, or ink application: General Electrical apparatus components and electronic components Medical devices and pharmaceuticals | 0.42 0.83 6.7 |
| Repair and maintenance cleaning: General Electrical apparatus components and electronic components Medical devices and pharmaceuticals: Tools, equipment, and machinery General work surfaces | 0.42 0.83 6.7 5.0 |
| Cleaning of coating or adhesive application equipment | 0.42 |
| Cleaning of ink application equipment: General Flexographic printing Gravure printing:Publication Packaging Screen printing Ultraviolet ink and electron beam ink application equipment, except screen printing Specialty flexographic printing | 0.42 0.42 0.83 0.42 4.2 5.4 0.83 |
| Cleaning of polyester resin application equipment not subject to 40 CFR 63, Subpart WWWW* | 0.42 |
(b) The owner or operator of a source that is subject to this rule shall employ only the following cleaning devices and methods: (2) Closed containers or hand-held spray bottles from which solvents are applied without a propellant-induced force.(3) Cleaning equipment that has a solvent container that is closed during cleaning operations, except when depositing and removing objects to be cleaned, and is closed during nonoperation with the exception of maintenance and repair to the cleaning equipment itself.(4) Remote reservoir cleaner that complies with all of the following: (A) Prevents solvent vapors from escaping from the solvent container by using such devices as a cover or a valve when the remote reservoir is not being used, cleaned, or repaired.(B) Directs solvent flow in a manner that will prevent liquid solvent from splashing outside of the remote reservoir cleaner.(C) Does not clean porous or absorbent materials, such as:(D) Uses only solvent containers free of all liquid leaks. Auxiliary equipment, such as pumps, pipelines, or flanges, shall not have any liquid leaks, visible tears, or cracks. Any liquid leak, visible tear, or crack detected shall be repaired within one (1) calendar day, or the leaking section of the remote reservoir cold cleaner shall be drained of all solvent and shut down until it is replaced or repaired.(5) Nonatomized solvent flow method where the cleaning solvent is collected in a container or a collection system that is closed except for solvent collection openings and, if necessary, openings to avoid excessive pressure buildup inside the container.(6) Solvent flushing where the cleaning solvent is discharged into a container that is closed except for solvent collection openings and, if necessary, openings to avoid excessive pressure buildup inside the container. The discharged solvent from the equipment must be collected into containers without atomizing into the open air. The solvent may be flushed through the system by air or hydraulic pressure or by pumping.(c) The owner or operator of a source that is subject to this rule is prohibited from atomizing any solvent unless the emissions are vented to VOC emission control equipment that meets the requirements of subsection (e).(d) Work practices shall be used to minimize VOC emissions from the use, handling, storage, and disposal of cleaning solvents and shop towels. Work practices shall include, at a minimum, but not be limited to, the following:(1) Covering open containers and used applicators.(2) Minimizing air circulation around cleaning operations.(3) Properly disposing of used solvent and shop towels.(4) Implementing equipment practices that minimize emissions, for example, keeping parts cleaners covered and maintaining cleaning equipment to repair solvent leaks.(e) As an alternative to complying with the requirements in subsections (a) and (b), the owner or operator of a source that is subject to this rule may comply with this rule by installing and operating VOC emission control equipment for the solvent cleaning operation. The VOC emission control equipment shall comply with the following requirements: (1) A capture efficiency of at least ninety percent (90%), by weight, for the VOC emissions.(2) Either a destruction efficiency of at least ninety percent (90%), by weight, or an outlet concentration of less than fifty (50) parts per million, by volume, dry basis, for the VOC emissions.(f) As an alternative to complying with the VOC content limits in subsection (a), the owner or operator of a source may use solvents or solvent solutions for industrial cleaning operations that have a VOC composite partial vapor pressure at or below eight (8) millimeters of mercury (mmHg) at twenty (20) degrees Celsius (sixty-eight (68) degrees Fahrenheit).(g) As an alternative to complying with the requirements in subsections (a) and (b), a manufacturer of coatings, inks, adhesives, or resins may comply with the following requirements: (1) Clean portable or stationary mixing vats, high dispersion mills, grinding mills, tote tanks, and roller mills by one (1) or more of the following methods:(A) Use a cleaning solvent that either contains less than one and sixty-seven hundredths (1.67) pounds per gallon of VOC or has a composite partial vapor pressure at or below eight (8) mmHg at twenty (20) degrees Celsius (sixty-eight (68) degrees Fahrenheit).(B) Comply with the following work practices:(i) Equipment being cleaned must be maintained leak free.(ii) Drain VOC-containing cleaning materials from the cleaned equipment upon completion of cleaning.(iii) Store or dispose of VOC-containing cleaning materials, including waste solvent, in a manner that will not cause or allow evaporation into the atmosphere.(iv) Store all VOC-containing cleaning materials in closed containers.(C) Collect and vent the emissions from equipment cleaning to a VOC emission control system that has an overall capture and control efficiency of at least eighty percent (80%), by weight, for the VOC emissions. If the reduction is achieved by incineration, at least ninety percent (90%) of the organic carbon shall be oxidized to carbon dioxide.(D) Use organic solvents other than those allowed in clause (A) provided not more than sixty (60) gallons of fresh solvent shall be used per month. Organic solvent that is reused or recycled (either on-site or off-site), for further use in equipment cleaning or the manufacture of coatings, inks, or adhesives shall not be included in this limit. All VOC-containing cleaning materials shall be stored in closed containers.(2) When using solvent for wipe cleaning, the owner or operator of a facility shall not:(A) use open containers for the storage or disposal of cloth or paper impregnated with organic compounds that are used for cleanup or the removal of coatings, inks, adhesives, or resins; or(B) store spent or fresh organic compounds to be used for cleanup or the removal of coatings, inks, adhesives, or resins in open containers. *This document is incorporated by reference.
