For purposes of the Spill Cleanup Policy only, where a spill of untested mineral oil occurs, the oil is presumed to contain >50 but <500 ppm PCBs. (See the definition of "spill" at §761.123.) No other assumptions or presumptions apply to spilled liquids.
Hi Jenny:
I would check with my local Government Agent Office.
It is also possible that your nearest Fire Department could assist you in finding the information.
I do know that I would not be breathing the air from the compressor.
Safety First!
Determine and report PCB concentrations on a weight-per-weight basis (such as ppm or mg/kg). You may determine and report the PCB concentration of liquids on a weight-per-volume basis (such as mg/L) if you also determine and report the density of the liquid
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).
You may use non-liquid materials such as concrete that were contaminated with PCBs $50 ppm provided the materials are decontaminated in accordance with a PCB disposal approval, or an applicable PCB spill cleanup policy, . The decontamination standard for concrete is <10 µg/100 cm² and requires that cleanup be initiated within 72 hours of the spill. If the state cleanup met these standards, you may continue to use the concrete.

definitely not a television question
commercial or residential ?
If clean up was done to state regs that concrete is good for any use
just in case
define contaminated
hazardous , carcinogenic ,nuclear, bio hazard
solid concrete slab poured post 1986 will have reo
if sound condition can be used, painted over, carpeted .sealed , tiled.what ever
if cracked up due to demolition
still ok to use for land fill or other rubble type back fill
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
correct PCBs clean up procedure is in this link http://infohouse.p2ric.org/ref/07/06045.htm
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
