Sec. 4.
(a) On and after July 23, 1995, the owner or operator of a source or facility subject to this rule shall implement housekeeping practices that include the following: (1) All equipment shall be maintained according to the manufacturer's specifications.(2) All fresh or used solvent shall be stored in closed containers.(3) All organic solvents used for line cleaning shall be pumped or drained into a closed container.(4) Finishing materials and cleaning materials shall be stored in closed containers.(b) On and after July 23, 1995, emissions from washoff operations shall be controlled by the following:(1) Using closed tanks for washoff.(2) Minimizing dripping by tilting or rotating the part to drain as much organic solvent as possible.(c) On and after July 23, 1995, conventional air spray guns shall not be used for applying finishing materials except under the following circumstances: (1) To apply finishing materials that have a VOC content no greater than one (1.0) kilogram of VOC per kilogram of solids (kg VOC/kg solids) (one (1.0) pound of VOC per pound of solid (lb VOC/lb solids)), as-applied.(2) For final touch-up and repair under one (1) of the following circumstances: (A) The finishing materials are applied after completion of the finishing operation.(B) The finishing materials are applied after the stain and before any other type of finishing material is applied, and the finishing materials are applied from a container that has a volume of no more than two (2) gallons.(3) If spray is automated, that is, the spray gun is aimed and triggered automatically, not manually.(4) If emissions from the finishing application station are directed to a control device.(5) The conventional air gun is used to apply finishing materials and the cumulative total usage of that finishing material is less than five percent (5.0%) of the total number of gallons of finishing material used during that semiannual reporting period.(6) The conventional air gun is used to apply stain on a part for which it is technically or economically infeasible to use any other spray application technology. Technical or economic infeasibility shall be demonstrated by submitting to the department a videotape, a technical report, or other documentation that supports the claim of technical or economic infeasibility. The following criteria shall be used, either independently or in combination, to support the claim of technical or economic infeasibility: (A) The production speed is too high or the part shape is too complex for one (1) operator to coat the part, and the application station is not large enough to accommodate an additional operator.(B) The excessively large vertical spray area of the part makes it difficult to avoid sagging or runs in the stain.(d) On and after May 1, 1996, the owner or operator of a wood furniture manufacturing operation subject to this rule shall ensure that spray guns are cleaned in an enclosed device that does the following:(1) Minimizes solvent evaporation during cleaning, rinsing, and draining operations.(2) Recirculates solvents during the cleaning operation so that the solvent is reused.(3) Collects solvent so that it is available for proper disposal or recycling.(e) On and after July 23, 1995, the owner or operator of a wood furniture manufacturing operation subject to this rule shall not use organic solvents containing more than eight percent (8.0%) by weight of VOC for cleaning spray booth components other than conveyors, continuous coaters and their enclosures, or metal filters, unless the spray booth is being refurbished. If the spray booth is being refurbished, that is, the spray booth coating or other material used to cover the booth is being replaced, no more than one (1.0) gallon of organic solvent shall be used to clean the booth.(f) On and after May 1, 1996, the owner or operator of a wood furniture manufacturing operation shall implement a written training program for all new and existing personnel, including contract personnel, involved in the implementation of this rule and shall provide initial and thereafter annual training. Records of training programs shall be kept on-site with the continuous compliance plan (CCP) for a minimum of three (3) years. Documentation of the training program shall include, at a minimum, the following:(1) A list of all personnel who are required to be trained by name and job description.(2) An outline of the topics to be addressed in the initial and annual training program for each person, or group of personnel. Topics to be addressed shall include, at a minimum, the following:(A) Applicable application techniques. (B) Applicable cleaning procedures.(C) Applicable equipment setup and adjustment to minimize finishing material usage and overspray.(D) Appropriate management of clean-up wastes.(3) Documentation of successful training completion for personnel involved in implementing this rule shall include the following:(A) A listing of topics addressed at the initial or annual training. At a minimum, topics addressed shall include those listed in subdivision (2).(B) A hands-on demonstration of the following:(i) Correct coating application techniques.(ii) Correct cleaning procedures.(iii) Correct equipment setup and adjustment to minimize coating usage and overspray.(iv) Appropriate management of clean-up wastes.(g) On and after May 1, 1996, each owner or operator of a wood furniture manufacturing operation subject to this rule shall implement a written leak inspection and maintenance plan that specifies the following:(1) A minimum visual inspection frequency of once per month for all equipment used to transfer or apply finishing materials or organic solvents.(2) An inspection schedule.(3) Methods for documenting the date and results of each inspection and any repairs that were made.(4) The time frame between identifying a leak and making the repair that adheres to the following schedule: (A) A first attempt at repair (such as tightening of packing glands) shall be made no later than five (5) working days after the leak is detected.(B) Final repairs shall be made within fifteen (15) working days, unless the leaking equipment is to be replaced by a new purchase, in which case repairs shall be completed within three (3) months.(h) On and after May 1, 1996, an organic solvent accounting form shall be maintained to record the following: (1) The quantity and type of organic solvent used each month for washoff and cleaning.(2) The number of pieces washed off, and the reason for the washoff.(3) The quantity of spent organic solvent generated from each activity, and the quantity that is recycled on-site or disposed off-site each month.Air Pollution Control Board; 326 IAC 8-11-4; filed Dec 5, 1995, 8:30 a.m.: 19 IR 1066; errata filed Apr 9, 1996, 2:30 p.m.: 19 IR 2045
