AUTHORITY: 38 M .R.S.A . 585-A EFFECTIVE DATE: October 3, 1989 Amended: October 2, 2000

May 18, 2010 BASIS STATEMENT Portions of the State ofMaine exceed both the state and federal ambient air quality standard for ozone. Volatile organic compounds (VOC) are a precursor in the formation of ozone. As part ofMaine's State Implementation Plan for Air Quality the state reducedVOCemissions frompaper coater sources through their air emission license. This regulationensures that all paper coater sources are treated consistently and will codify paper coater requirements for future sources. Comments fromthe U.S. Environmental Protection Agency suggested minor changes to ensure consistency with EPA's model regulation . BASIS STATEMENT FORAMENDMENT OF AUGUST 17, 2000 This amendment reduces the recordkeeping requirements for sources utilizing low solvent coating technology froma daily to a monthly basis, thereby clarifying and simplifying recordkeeping and compliance efforts. In addition to reducing recordkeeping requirements, this regulationwas also amended to incorporate an alternative emission limit of a 95 percent control efficiencyfor coating units utilizing add-on controls. In addition to the Basis Statement above, the Department has filed with the Secretary of State response to representative comments received during the comment period.

BASIS STATEMENT FORAMENDMENT OF APRIL 15, 2010 Section 184 ofthe CleanAirAct requires states to implement or update reasonably available control technology (RACT) controls on all major VOCand NOx emission sources and on source categories covered by a Control Technique Guideline (CTG) document. EPAdefines RACT as the lowest emission limit that a particular source is capable ofmeeting by the application of control technology that is reasonably available considering technological and economic feasibility. In May 1977, EPApublished a CTGfor controlling VOCemissions fromsurface coating ofpaper, which it updated in September 2007. The paper, filmand foil coatings include coatings that are applied to paper, filmand foil surfaces in the manufacturing of several major product types including pressure sensitive tape and labels, industrial and decorative laminates, and photographic film . This category also includes coatings applied during miscellaneous coating operations of corrugated and solid fiber boxes and folding paperboard boxes. These amendments add control requirements for the surface coating of film and foil substrates and incorporate work practices. In addition tothe Basis Statement above, the Department has filed with the Secretary of State response to representative comments received during the comment period. Chapter 123
