Section NR 247.02 - Applicability

The effluent limitations, standards of performance, pretreatment standards, and other provisions in this chapter are applicable to pollutants or pollutant properties in discharges of process waste resulting from manufacture in any of the following subcategories.

(1) INSULATION FIBERGLASS. This subcategory covers the manufacture of insulation fiberglass by continuously fiberizing molten glass and chemically bonding it into a wool like material.

(2) SHEET GLASS. This subcategory covers the manufacture of sheet glass by mixing several mineral ingredients, melting the mixture in a furnace, and drawing the sheet vertically from a melting tank.

(3) ROLLED GLASS. This subcategory covers the manufacture of rolled glass by mixing several mineral ingredients, melting the mixture in a furnace, and cooling the melt with rollers.

(4) PLATE GLASS. This subcategory covers the manufacture of plate glass by mixing several mineral ingredients, melting the mixture in a furnace, pressing the melt between rollers, and grinding and polishing the surface.

(5) FLOAT GLASS. This subcategory covers the manufacture of float glass by mixing several mineral ingredients, melting the mixture in a furnace, and floating the melt on a molten tin oath.

(6) AUTOMOTIVE GLASS TEMPERING. This subcategory covers the processes in which glass is cut, the cut edges are ground and polished, and the glass is then bent and tempered to form automobile side and back windows.

(7) AUTOMOTIVE GLASS LAMINATING. This subcategory covers the processes in which glass is cut, bent, washed, and plastic sheet laminated to produce automobile windshields.

(8) GLASS CONTAINER MANUFACTURING. This subcategory covers the process in which raw materials are melted in a furnace and mechanically processed into glass containers.

(9) MACHINE PRESSED AND BLOWN GLASS. (This subcategory is reserved.)

(10) GLASS TUBING MANUFACTURING. This subcategory covers the process in which raw materials are melted in a furnace and glass tubing is mechanically drawn horizontally from the furnace by the Danner process which requires intermittent cullet quenching.

(11) TELEVISION PICTURE TUBE ENVELOPE MANUFACTURING. This subcategory covers the process in which raw materials are melted in a furnace and made into television picture tube envelopes.

(12) INCANDESCENT LAMP ENVELOPE MANUFACTURING. This subcategory covers the process in which;

(a) Raw materials are melted in a furnace and mechanically processed into incandescent lamp envelopes, or

(b) Such envelopes are made and then etched with hydrofluoric acid to produce frosted envelopes.

(13) HAND PRESSED AND BLOWN GLASS MANUFACTURING. This subcategory covers the process in which raw materials are melted in a furnace and hand pressed or blown to produce glassware. The subcategory is further subdivided to cover:

(a) The production of leaded glass using hydrofluoric acid finishing techniques,

(b) The production of non-leaded glass using hydrofluoric acid finishing techniques, and

(c) The production of leaded or non-leaded glass without the use of hydrofluoric acid finishing techniques.
