OAR 340-245-9010: Colored Art Glass Manufacturing Facility Rules; Definitions

The definitions in OAR 340-200-0020 and this rule apply to OAR 340-245-9000 through 9095. If the same term is defined in this rule and 340-200-0020, the definition in this rule applies to this division. (1) “Colored Art Glass Manufacturer” or “CAGM” means a facility that meets the applicability requirements in OAR 340-245-9000 and refers to the owner or operator of such a facility when the context requires. (2) “Chromium III” means chromium in the +3 oxidation state, also known as trivalent chromium. (3) “Chromium VI” means chromium in the +6 oxidation state, also known as hexavalent chromium. (4) “Chromium”, without a following roman numeral, means total chromium. (5) “Controlled” means the glassmaking furnace emissions are treated by an emission control device approved by DEQ. (6) “Cullet” means pieces of finished glass that, when mixed with raw materials and charged to a glassmaking furnace, is used to produce new glass. Cullet does not include frit as defined in subsection (9)(a). Cullet is not considered to be a raw material. (7) “Emission control device” means control device as defined in OAR chapter 340, division 200. (8) “Finished glass” means the final glass product that results from melting and refining materials in a glassmaking furnace. Finished glass that has been remelted without the addition of raw materials is still finished glass. (9) “Frit” means both of the following: (a) Granules of glassified or vitrified material that is not made from finished glass, and which contains a higher proportion of glassmaking HAP than would be found in a finished glass. The purpose of such material includes, but is not limited to, making powdered glassmaking HAPs safer to handle by combining them with silica or other oxides. (b) Granules of crushed finished glass. (10) “Glassmaking furnace” means a refractory-lined vessel in which raw materials are charged and melted at high temperature to produce molten glass. (11) “Glassmaking HAP” means arsenic, cadmium, chromium, lead, manganese, nickel or selenium in any form, such as the pure chemical element, in compounds or mixed with other materials. (12) “Raw material” means: (a) Substances that are intentionally added to a glass manufacturing batch and melted in a glassmaking furnace to produce glass, including but not limited to: (A) Minerals, such as silica sand, limestone, and dolomite; (B) Inorganic chemical compounds, such as soda ash (sodium carbonate), salt cake (sodium sulfate), and potash (potassium carbonate); (C) Oxides and other compounds of chemical elements, such as lead oxide, chromium oxide, and sodium antimonate; and (D) Ores of chemical elements, such as chromite and pyrolusite. (b) Glassmaking HAPs that are naturally-occurring trace constituents or contaminants of other substances are not considered to be raw materials. (c) Raw material includes materials that contain glassmaking HAPs in amounts that materially affect the properties of the finished product, such as its color, texture or bubble content. Such materials may be powdered, frit, or in some other form. For the purpose of this definition, frit as described in subsection (9)(a) is a raw material, but frit as described in subsection (9)(b) is not a raw material. (d) Cullet and material that is recovered from a glassmaking furnace control device for recycling into the glass formulation are not considered to be raw materials. (13) “Tier 1 CAGM” means a CAGM that produces at least 5 tons per year, but less than 100 tons per year, of glass using raw materials that contain glassmaking HAPs in glassmaking furnaces that are only electrically heated. (14) “Tier 2 CAGM” means: (a) A CAGM that produces 5 tons per year or more of glass using raw materials that contain glassmaking HAPs in glassmaking furnaces, at least one of which is fuel-heated or combination fuel- and electrically-heated; or (b) Produces 100 tons per year or more of glass using raw materials that contain glassmaking HAPs in any type of glassmaking furnace. (15) “Uncontrolled” means the glassmaking furnace emissions are not treated by an emission control device approved by DEQ. (16) “Week” means Sunday through Saturday.
