§ 426.120 - Applicability; description of the incandescent lamp envelope manufacturing subcategory.
The provisions of this subpart are applicable to discharges resulting from the processes by which (a) raw materials are melted in a furnace and mechanically processed into incandescent lamp envelopes or (b) incandescent lamp envelopes are etched with hydrofluoric acid to produce frosted envelopes.
§ 426.121 - Specialized definitions.
For the purpose of this subpart:
(a) Except as provided below, the general definitions, abbreviations and methods of analysis set forth in part 401 of this chapter shall apply to this subpart.
(b) The term “furnace pull” shall mean that amount of glass drawn from the glass furnace or furnaces.
(c) The term “oil” shall mean those components of a waste water amenable to measurement by the technique or techniques described in the most recent addition of “Standard Methods” for the analysis of grease in polluted waters, waste waters, and effluents, such as “Standard Methods,” 13th Edition, 2nd Printing, page 407.
(d) The term “product frosted” shall mean that portion of the “furnace pull” associated with the fraction of finished incandescent lamp envelopes which is frosted; this quantity shall be calculated by multiplying “furnace pull” by the fraction of finished incandescent lamp envelopes which is frosted.
§ 426.122 - Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available.
Except as provided in §§ 125.30 through 125.32, any existing point source subject to this subpart shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT):

|---|
1 No limitation.
2 Within the range 6.0 to 9.0.
§ 426.123 - Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable.
Except as provided in §§ 125.30 through 125.32, the following limitations establish the quantity or quality of pollutants or pollutant properties, controlled by this section, which may be discharged by a point source subject to the provisions of this subpart after application of the best available technology economically achievable:
(a) [Reserved]
(b) Any manufacturing plant which frosts incandescent lamp envelopes shall meet the following limitations with regard to the finishing operations.
| Effluent characteristic | Effluent limitations | Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed— | Metric units (g/kkg of product frosted) | Fluoride | 104.0 | 52.0 | Ammonia | 240.0 | 120.0 | English units (lb/1,000 lb of product frosted) | Fluoride | 0.104 | 0.052 | Ammonia | 0.24 | 0.12 |
|---|
§ 426.124 - [Reserved]
§ 426.125 - Standards of performance for new sources.
The following standards of performance establish the quantity or quality of pollutants or pollutant properties, controlled by this section, which may be discharged by a new source subject to the provisions of this subpart:
(a) Any manufacturing plant which produces incandescent lamp envelopes shall meet the following limitations with regard to the forming operations.
| Effluent characteristic | Effluent limitations | Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed— | Metric units (g/kkg of furnace pull) | Oil | 90.0 | 45.0 | TSS | 90.0 | 45.0 | pH | ( 1) | ( 1) | English units (lb/1,000 lb of furnace pull) | Oil | 0.09 | 0.045 | TSS | 0.09 | 0.045 | pH | ( 1) | ( 1) |

§ 426.126 - Pretreatment standards for new sources.
Any new source subject to this subpart that introduces process wastewater pollutants into a publicly owned treatment works must comply with 40 CFR part 403. In addition, the following pretreatment standard establishes the quantity or quality of pollutants or pollutant properties controlled by this section which may be discharged to a publicly owned treatment works by a new point source subject to the provisions of this subpart. Because of the recognition that animal and vegetable oils can be adequately removed in a publicly owned treatment works, whereas mineral oil may not be readily removed and may pass through untreated, two separate limitations are established.
| Pollutant or pollutant property | Pretreatment standards | Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed— | Metric units (g/kkg of furnace pull) | Oil (animal and vegetable) | ( 1) | ( 1) | Oil (mineral) | 230.0 | 115.0 | TSS | ( 1) | ( 1) | pH | ( 1) | ( 1) | English units (lb/1,000 lb of furnace pull) | Oil (animal and vegetable) | ( 1) | ( 1) | Oil (mineral) | 0.23 | 0.115 | TSS | ( 1) | ( 1) | pH | ( 1) | ( 1) | Metric units (g/kkg of product frosted) | Fluoride | 104.0 | 52.0 | Ammonia | ( 1) | ( 1) | TSS | ( 1) | ( 1) | pH | ( 1) | ( 1) | English units (lb/1,000 lb of product frosted) | Fluoride | 0.104 | 0.052 | Ammonia | ( 1) | ( 1) | TSS | ( 1) | ( 1) | pH | ( 1) | ( 1) |

Except as provided in §§ 125.30 through 125.32, any existing point source subject to this subpart shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best conventional pollutant control technology (BCT): The limitations shall be the same as those specified for conventional pollutants (which are defined in § 401.16) in § 426.122 of this subpart for the best practicable control technology currently available (BPT).
