Illinois Governor Signs SB3917, PFAS Sampling Requirements for NPDES Permits
Summary
Illinois Governor J.B. Pritzker signed SB3917 on April 16, 2026, amending the Illinois Environmental Protection Act to add PFAS sampling requirements for facilities holding NPDES discharge permits. For major facilities designated by the EPA, publicly owned treatment works must conduct periodic sampling of influent, effluent, and biosolids for all PFAS substances with accredited wastewater analytical methods, while all other facilities must perform periodic effluent sampling. New NPDES applications for wastewater with potential PFAS content must fully characterize the discharge through sample results, and no land-application permits for sludge or biosolids may be issued without PFAS sample data.
“Provides that all National Pollutant Discharge Elimination System permits authorizing a discharge from a facility designated by the Environmental Protection Agency and the United States Environmental Protection Agency as a major facility, shall, at a minimum, require for publicly owned treatment works, periodic sampling of influent, effluent, and biosolids for all perfluoroalkyl and polyfluoroalkyl substances for which there are accredited wastewater analytical methods”
Industrial and municipal NPDES permit holders in Illinois that have not previously tested for PFAS should review their current discharge characterization and determine whether accredited analytical methods are available for the PFAS compounds relevant to their operations. Facilities applying for new or renewed NPDES permits with potential PFAS content should prepare for mandatory full-discharge characterization requirements now, rather than at the application stage, to avoid delays.
What changed
SB3917 adds a new PFAS sampling mandate to the Illinois Environmental Protection Act for all NPDES-permitted discharges. Facilities designated as major by EPA must sample influent, effluent, and biosolids for PFAS on a periodic basis; non-major facilities must sample effluent. Any NPDES permit application for wastewater with potential PFAS content must include full characterization results, and no land-application permit for sludge or biosolids may be issued without PFAS sample data.
Municipalities operating publicly owned treatment works and industrial facilities discharging under NPDES permits in Illinois should inventory their current permit conditions and sampling protocols. Facilities not currently monitoring for PFAS will need to incorporate accredited analytical methods into their compliance programs. Permit writers and environmental consultants advising discharge facilities should anticipate updated permit language requiring PFAS characterization and periodic follow-up sampling.

Provides that the Agency shall not issue any permit under specified provisions for the land application of a sludge or biosolids unless the application includes sample results for the sludge or biosolids for all perfluoroalkyl and polyfluoroalkyl substances for which there are accredited wastewater analytical methods. Provides that any permit issued under specified provisions for the land application of a sludge or biosolids shall require, at minimum, periodic sampling of the sludge or biosolids for all perfluoroalkyl and polyfluoroalkyl substances for which there are accredited wastewater analytical methods.
