Sec. 10.
(a) This section establishes the emission limitations for flat wood manufacturing and surface finishing of the following: (1) Printed interior panels made of hardwood plywood and thin particle board. "Printed interior panels" means panels whose grain or natural surface is obscured by fillers and basecoats upon which a simulated grain or decorative pattern is printed. "Hardwood particleboard" means a manufactured board one-fourth (1/4) inch or less in thickness made of individual wood particles that have been coated with a binder and formed into flat sheets by pressure.(2) Natural finish hardwood plywood panels. "Natural finish hardwood plywood panels" means panels whose original grain pattern is enhanced by essentially transparent finishes frequently supplemented by fillers and toners.(3) Hardboard paneling with Class II finishes. "Hardboard" means a panel manufactured primarily from inter-felted ligno-cellulosic fibers that are consolidated under heat and pressure in a hot press. "Class II finish" means finishes that meet the specifications of Voluntary Product Standard PS-59-73 as approved by the American National Standards Institute.(4) Exterior siding. Exterior siding may be made of solid wood, hardboard, or waferboard.(5) Tileboard. "Tileboard" means a premium interior wall paneling product made of hardboard that is used in high moisture areas of the home, such as kitchens and bathrooms.(b) This section does not apply to coating lines used solely in the manufacture of exterior siding, tileboard, or particleboard used as a furniture component.(c) If a coating line is used both for coating paneling subject to this section as described in subsection (a) and for paneling exempt from this section as described in subsection (b) then any control equipment installed on the line shall be operated at all times when the line is in use.(d) No owner or operator of a flatwood manufacturing facility subject to this section shall emit VOC from a coating line in excess of the following:(1) Two and nine-tenths (2.9) kg per one hundred (100) square meters of coated finished product (6.0 lb/1,000 sq ft) from printed interior panels, regardless of the number of coats applied.(2) Five and eight-tenths (5.8) kg per one hundred (100) square meters of coated finished product (12.0 lb/1,000 sq ft) from natural finish hardwood plywood panels, regardless of the number of coats applied.(3) Four and eight-tenths (4.8) kg per one hundred (100) square meters of coated finished product (10.0 lb/1,000 sq ft) from Class II finishes on hardboard panels, regardless of the number of coats applied.(e) On and after April 1, 2011, the owner or operator of a flatwood manufacturing facility in which the total actual VOC emissions from all flatwood paneling coating lines, including related cleaning activities, are equal to or exceed fifteen (15) pounds per day, before add-on controls, located in Lake County or Porter County, shall comply with the following:(1) VOC emission limitations as follows: | Paneling Category | lb of VOC per gallon (grams VOC per liter) of surface coating, ink, or adhesive (excluding water and exempt compounds) | lb VOC per gallon solids (grams VOC per liter solids) |
| Printing interior panels made of hardwood, plywood, or thin particleboard | 2.1 (250) | 2.9 (350) |
| Natural finish hardwood plywood panels | 2.1 (250) | 2.9 (350) |
| Class II finishes on hardboard panels | 2.1 (250) | 2.9 (350) |
| Tileboard | 2.1 (250) | 2.9 (350) |
| Exterior siding | 2.1 (250) | 2.9 (350) |
(2) An owner or operator may achieve compliance with this subsection by using a capture and control device that achieves a minimum overall VOC control efficiency of ninety percent (90%).(3) As an alternative to subdivision (1), 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).(4) Work practices shall be used to minimize VOC emissions from mixing operations, storage tanks, and other containers, and handling operations for coatings, thinners, cleaning materials, and waste materials. Work practices shall include the following, at a minimum: (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.
