326 IAC 8-2-5 Paper coating operations

Sec. 5. (a) This section establishes emission limitations for web coating or saturation processes of paper, plastic, metal foil, and pressure sensitive tapes and labels regardless of substrate. Excluded from this category are single pieces of equipment that meet the emission limitations contained in 326 IAC 8-5-5 that conduct packaging rotogravure printing, publication rotogravure printing, or flexographic printing operations in line with surface coating lines. (b) No owner or operator of a coating line subject to this section may cause, allow, or permit the discharge into the atmosphere of any VOC in excess of thirty-five hundredths (0.35) kilogram per liter of coating (two and nine-tenths (2.9) pounds per gallon) excluding water, delivered to the coating applicator from a paper, plastic, metal foil, or pressure sensitive tape/labels coating line. (c) On and after April 1, 2011, the owner or operator of a coating line in which the total actual VOC emissions from all paper coating operations, including related cleaning activities, are equal to or exceed fifteen (15) pounds per day located in Lake County or Porter County, before add-on controls, shall comply with the following: (1) For coating lines with potential VOC emissions of twenty-five (25) tons per year or greater the following VOC emission limitations apply: (A) Two-tenths (0.2) kilogram VOC/kg solids (two-tenths (0.2) lb VOC/lb solids) applied for pressure sensitive tape and label coating. (B) Four-tenths (0.4) kilogram VOC/kg solids (four-tenths (0.4) lb VOC/lb solids) applied for paper, film, and foil coating. (2) As an alternative to subdivision (1), an owner or operator may achieve compliance using a capture and control device that achieves a minimum overall VOC control efficiency of ninety percent (90%). (3) An owner or operator may also achieve compliance by using a combination of subdivisions (1) and (2). The required overall add-on control efficiency, when combining add-on control with low VOC coatings, must be determined using 326 IAC 8-1-2(c), except that the units for actual VOC content and equivalent emissions limit is in pound of VOC per pound of coating solids instead of pound of VOC per gallon of coating solids. (4) Work practices shall be used to minimize VOC emissions from mixing operations, storage tanks, and other containers, and handling operations for cleaning material, and cleaning-related waste materials. Work practices shall include, but not be limited to, the following: (A) Store all VOC containing materials in closed containers. (B) Ensure that mixing and storage containers used for VOC containing materials are kept closed at all times except when depositing or removing these materials. (C) Minimize spills of VOC containing cleaning materials. (D) Convey VOC containing cleaning materials from one (1) location to another in closed containers or pipes. (E) Minimize VOC emissions from the cleaning of storage, mixing, and conveying equipment.
