   c.  Automatic Blanket Wash System--Equipment used to remotely clean lithographic blankets which may include, but is not limited to those utilizing a cloth and expandable bladder, brush, spray or impregnated cloth system.

   d.  Batch--A supply of fountain solution that is prepared and used without alteration until completely used or removed from the printing process. For the purposes of this general permit, this term includes solutions that are either prepared in discrete batches or solutions that are continuously blended with automix units.

   e.  Cleaning Solution--Liquid solvents or solutions used to remove ink and debris from the operating surfaces of the printing press and its parts.

   f.  Dampening System--Equipment used to deliver the fountain solution to the lithographic plate.

   g.  Fountain Solution--A mixture of water, nonvolatile printing chemicals and an additive (liquid) that reduces the surface tension of the water so that it spreads easily across the printing plate surface. The fountain solution wets the nonimage area so that the ink is maintained within the image areas. Nonvolatile additives include mineral salts and hydrophilic gums. For the purpose of this general permit, the additives may include a VOC content of 5.0% or less. Alcohol and alcohol substitutes, including isopropyl alcohol, glycol ethers and ethylene glycol, are the most common VOC additives used to reduce the surface tension of the fountain solution.

   h.  Fountain Solution Recirculating Reservoir--The collection tank which accepts fountain solution recirculated from printing unit(s). The tanks typically contains a coarse filter to remove contaminants from the fountain solution and in some cases, are equipped with cooling coils for refrigeration of the fountain solution.

   i.  Inking System--A series of rollers used to meter the ink onto the lithographic plate. The system can include agitators, pumps, and totes and other types of ink containers.

   j.  Lithography--A planographic printing process where the image and nonimage areas are chemically differentiated; the image area is oil receptive and the nonimage area is water receptive. This method differs from other printing methods, where the image is typically printed from a raised or recessed surface.

   k.  Nonheatset--A lithographic printing process where the printing inks are set without the use of heat. Traditional nonheatset inks set and dry by absorption and/or oxidation of the ink oils. For the purposes of this general permit, ultraviolet-cured and electron beam-cured inks are considered nonheatset, although radiant energy is required to cure these inks.

   l.  Offset--A printing process that transfers the ink film from the lithographic plate to an intermediary surface (blanket), which, in turn, transfers the ink film to the substrate.

   m.  Press--For purposes of this general permit, a printing production assembly composed of one or more units used to produce a printed substrate or a web. The term includes any associated coating, spray powder application or infra-red heating units.

   n.  Unit--The smallest complete printing component, composed of inking and dampening systems, of a printing press.

   o.  VOC Composite Partial Vapor Pressure--The sum of the partial pressure of the compounds defined as VOCs. VOC composite partial pressure is calculated as follows:

Where:

Wi= Weight of the ''i''th VOC compound, in grams
Ww= Weight of water, in grams
Wc= Weight of exempt compound, in grams
MWi= Molecular weight of the ''i''th VOC compound, in g/g-mole
MWw= Molecular weight of water, in g/g-mole
MWc= Molecular weight of exempt compound, in g/g-mole

12-Month Totals

   The U.S. Environmental Protection Agency requires the Department to track emissions on a 12-month total basis rather than on a calendar basis. This means that emission estimates should be recalculated each month totaling emissions that occurred during the last 12 months. For example, at the end of March, 1998 you would total the emissions which occurred from April, 1997 through March, 1998; at the end of April, 1998 you would total the emissions which occurred from May, 1997 through April, 1998, etc.
