check for any faults with the finished circuit board product. Next he showed us the photo room where they use an ammonia based machine to produce the circuitry image onto film. The resulting waste ammonia is then used for pH adjusting in the waste treatment area. During the inspection, Mr. Smith stated that 16"x 20" trays containing developer and fixer solutions were disposed of in their waste treatment system. Mr. Smith stated he did not use a metal recovery system because they (RV Circuits) only dispose of approximately 2 gallons a month. We then entered the silk screening room. Mr. Smith stated that the caustic soda used in this process is batch treated prior to discharge. Mr. Smith then showed us the gold plating/nickel plating area where the solder fingers are plated first with nickel, then with gold. Mr. Smith explained that the nickel plating solution is run through carbon filters and these filters are then disposed of under manifest. The gold is sent to a reclaimer for processing. We then entered the hot oil reflow area which had raised wooden floor slats for walking above the floor. The floor had a lot of hot oil reflow spillage beneath the wooden slats. There was a continuous discharge going down a sink in the room where Mr. Hyde and Ms. Archbold collected a sample. Ms. Archbold pointed to a 55 gallon drum that contained reflow oil and was labeled with masking tape as such. I asked Mr. Smith what they did with the reflow oil when it was spent and Mr. Smith stated they take it out a couple of buckets at a time and place it in a 55 gallon drum to eventually be hauled as hazardous waste. Mr. Smith then proceeded to show me the series of drag out tanks used to process the circuit boards. This floor also contained many areas of liquid spillage and the walking area was covered with wooden slats. The ammonia etch area was located just before the waste treatment area. I noted an extremely strong ammonia odor which was being minimized with the use of fans aimed up at the ceiling. When we finished touring the inside processing area, Mr. Smith notified me that he had an 11:30 a.m. appointment. I told him that we could resume the inspection at 1:30 p.m. , and we all left the facility. Mr. Hyde, Ms. Archbold, Charles Hunt and myself met back at the facility at approximately 1330 hours. We met with J. R. Tupas, who showed us the waste water treatment and hazardous waste storage area. While Ms. Archbold and Mr. Hyde questioned Mr. Tupas about the waste water treatment, Mr. Hunt and I inspected the hazardous waste storage area. Several storage violations were noted. Most of the drums were unlabeled, uncovered, and if found labeled, were dated beyond the 90 day storage limit. Mr. Smith rejoined the inspection group at about 1400 hours. Mr. Hunt and I followed Mr. Tupas to his office to review the facility paperwork. Several
