- NEG Television Products, Inc. conduct nickel plating & stripping and chrome plating & stripping operations at the above location. Stainless steel molds, plungers and shells are chrome or nickel plated and used to form glass television face panels produced at the facility.

The nickel plating operation consists of eight tanks. The first tank is an alkaline clean followed by a water rinse, a hydrochloric acid wash, a water rinse, a sulfuric acid wash, and three nickel plating tanks. All tanks, with exception of the two water rinse tanks, vent to the ventilation system. The nickel stripping operation consists of two non

- cyanide strip tanks, a water w ash, and a water bath. Only the two strip tanks discharge to the ventilation system.

The chrome plating operation consists of four chrome plating tanks, an alkaline rinse tank and two water rinse tanks. All tanks vent to existing ventilation system. The chrome stripping operation consists of three tanks. First is the strip tank containing a potassium phosphate solution followed by an alkaline wash tank and water rinse tanks. All vent to a ventilation
system.Data File

The emissions from the chrome plating oper ation are controlled by a MAPCO Enforcer III scrubber and combined with the uncontrolled emissions from the nickel plating & stripping and chrome stripping operations in a common 34

- inch inside diameter stack and discharged to the atmosphere.

On July 18, 1997 personnel from Monarch Analytical Laboratories, Inc. conducted emission testing for Chromium VI in the outlet stack of above plating operations utilizing California Air Resources Board (CARB) Method 425 with colorimetric analysis technique (outlined i n 40 CFR, Part 63.344 (c)(2)(i)). The test was performed at the facility’s request, after scrubber was installed, to establish compliance with standard listed in 40 CFR, Subpart N, Section 63.342. The colorimetric analytical technique weight requirement of 33

- 66 microgram was not achieved because of insufficient sample times and volumes. The measured weights for run nos. 1

- 3 were 5, 9 and 8 micrograms, respectively. The consultant did not utilized either of the two more accurate analytical methods, Abso rption Graphite Furnace (AAGF) or Ion Chromatography with

Post

- column Reactor (ICPCR), to determine the weight of the samples. Consequently, the sample weight and emission concentration results are considered to be invalid and unacceptable to the Department.

The consultant has been informed that he has the option of reanalyzing the test samples and resubmitting recalculated emission results for review.
