If I test a transformer for disposal and find that it contains PCBs in concentrations 500 ppm, must I register the transformer?

it is but u take the transfermation out of it first to avoid it

If you do not know the PCB concentration of a transformer that is in use, apply the concentration assumptions for use in §761.2. If you are required to assume that the transformer contains $500 ppm PCBs, you must register it. http://www.qjpcb.com/ whatsapp:+8618688621379 http://www.qjpcb.com/ Skype : wang.michelle35

ya? it is a peer review HOWEVER

depends on the level of PPM PCBs

and questionable equipment used to manufacture fill fluid containing PCBs after any year
at a higher than industry stds .....should be de contaminated or disposed of correctly

This depends on the concentration of PCBs in the potting material and whether the ballast contains an intact or non-intact PCB small capacitor. If the PCB concentration of the potting material is <50 ppm and the ballast contains either no PCB small capacitor or an intact and non-leaking PCB small capacitor, you can dispose of the ballast as municipal solid waste (see §761.60(b)(2)(ii)). If the PCB concentration of the potting material is $50 ppm and the ballast contains either no PCB small capacitor or an intact and non-leaking PCB small capacitor, you can dispose of the ballast as PCB bulk product waste in a TSCA incinerator, a TSCA/RCRA landfill, a facility permitted, licensed, or registered by a state as a municipal or non-municipal non-hazardous waste landfill, or by means of an approved destruction method, decontamination, or risk-based disposal method (see §761.62). Regardless of the PCB concentration of the potting material, you must dispose of ballasts containing non-intact or leaking capacitors as PCB bulk product waste in accordance with §761.62(a) or (c).

Yes. You must characterize a natural gas pipeline system by analyzing
organic liquids collected at the condensate collection points (see §761.60(b)(5)(iii)). If there are no liquids present you must wipe sample in accordance with Subpart M, §761.250(a)(2). Select the proper sampling position along the pipe by following the directions in §761.247 (c) and (d). Then, according to §761.247(c)(3)(iii), if the entire population of pipe to be wipe sampled is porous and there are no non-porous surfaces available, assume that the pipe contains PCBs >50 ppm but <500 ppm and is PCB-Contaminated. Subsequently, an appropriate provision in §761.60(b)(5)(i) must be used to abandon the pipe. If you do not want to assume that the pipe is PCB-Contaminated, then you may apply for an alternate sampling plan under §761.61(c).

what a question
best get the exact answer from your local govt authorities

even if 50ppm was acceptable on compressors and air tanks
it would be wise to have the units cleaned and de- contaminated

Polychlorinated Biphenyls (PCBs).......
PCBs can bioaccumulate in the fatty tissue of fish, birds, and mammals after entering through the lungs, skin, or gastrointestinal tract. They are suspected human carcinogens and have been shown to be teratogenic (i.e., capable of inducing mutations in the offspring of affected organisms).
in general
50ppm in certain situations and disposal requirements is the max

The Disposal Amendments do not require you to register voltage regulators with PCB concentrations $500 ppm. This is because data available to EPA show that most voltage regulators contain mineral oil as a dielectric fluid, and very few would contain PCB concentrations $500 ppm, http://www.qjpcb.com/ Skype : wang.michelle35

Silicone dielectric fluid was manufactured not to contain PCBs. There is no assumption applicable to transformers known to be silicone-filled while in use, regardless of the date of manufacture. These transformers are regulated based on their actual PCB concentration. It is possible the transformer could have become contaminated during servicing with fluid containing $50 ppm PCBs
