Must I assume that a transformer has a PCB concentration of 500 ppm only if both the date of manufacture and the type of fluid are unknown?

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).
