SB 138

Department of Environmental Quality; industrial wastewater; publicly owned treatment works; PFAS monitoring. Directs the Department of Environmental Quality to require quarterly monitoring for one year for per- and polyfluoroalkyl substances (PFAS) for every industrial wastewater source that discharges pollutants into a publicly owned treatment works. The bill requires (i) any owner or operator of such industrial wastewater source to submit the results of such monitoring quarterly to the publicly owned treatment works and the Department; (ii) if quarterly monitoring reveals PFAS in any amount, the owner or operator of such industrial wastewater source to continue to monitor for PFAS on a quarterly basis and submit the results of such monitoring to the publicly owned treatment works and the Department; and (iii) any new industrial wastewater source that discharges pollutants into a publicly owned treatment works to monitor discharges from each outfall for PFAS and submit the results of such monitoring within 90 days of the commencement of such discharges to the publicly owned treatment works and the Department. The bill allows the Department to reduce the frequency of such required monitoring in clause (ii) if an industrial wastewater source has at least two consecutive quarters of test results with all analyzed PFAS below the method detection level. The bill also requires any owner or operator of an industrial wastewater source that discharges pollutants into a publicly owned treatment works to submit the initial quarterly monitoring results for PFAS as required by the bill within 30 days of the effective date of the bill.
