However, the company does not have a permit to discharge those specific types of PFAS. Therefore asked it proposes an extension of the existing permit, with limit values for each of the 13 (ultra) short-chain PFAS found.
Some of the limit values that 3M itself proposed are very far below the established quantities. For example, the application shows that 3M is considering a standard of 145 micrograms per liter for PFPrA in the process wastewater, while measurements in the same wastewater showed an average of 769 micrograms per liter, with even peaks of up to 6,770 micrograms.
In this way, 3M hoped to bring the discharges found into line after all. It argued, among other things, that the additional pollution caused by the 13 substances would not make a significant difference compared to the PFAS pollution that is already present in the Scheldt (and which was largely caused by 3M itself).
