A Case Study Of The Continued Use Of PCB-Contaminated Concrete Through Implementation Of The 40 CFR 761.30(P) Use Authorization
The 40 CFR 761.30(p) use authorization for PCB-contaminated porous surfaces was applied to concrete floors at an electric utility’s transformer shop and PCB storage building. This authorization allows PCB-contaminated concrete to be managed in place while it remains in service, provided that it is surface washed, encapsulated, and marked to indicate the presence of
PCBs that will ultimately need to be disposed of. Experiences gained from the implementation of this process for continued-use are presented.
