TRANSMITTAL LETTER FOR BOARD MEETING OF NOVEMBER 20, 2025
COMMITTEE ON INDUSTRIAL WASTE AND WATER POLLUTION
Mr. John P. Murray, Acting Executive Director
Title
Report on Public Notification of Dischargers found in Significant Noncompliance with Pretreatment Standards or Other Requirements
Body
Dear Sir:
The federal General Pretreatment Regulations (40 CFR 403.8[f][2][viii]) require the Metropolitan Water Reclamation District of Greater Chicago (District) to comply with the public participation requirements of 40 CFR 25 in the enforcement of National Pretreatment Standards. These requirements include a provision for providing annual public notification in a newspaper of general circulation that provides meaningful public notice within the jurisdiction of the District, the names of industrial users (IUs) which were in significant noncompliance with applicable pretreatment standards or other requirements.
To comply with this provision, the Monitoring and Research Department annually compiles a list of IUs which were considered in significant noncompliance with the General Pretreatment Regulations and the District’s Sewage and Waste Control Ordinance (Ordinance).
The IUs noted on pages 1 to 4 of Attachment 1 have been determined to be in significant noncompliance of the applicable pretreatment standards or other requirements for the 2024 calendar year. These 52 IUs were notified via email on October 1, 2025, and October 2, 2025. This email explained the criteria used to identify an IU in significant noncompliance and notified the recipient of the forthcoming publication of this list. Additionally, the email advised all IUs on the attached list of their opportunity to provide written comments to the District regarding the appropriateness of their publication as being in significant noncompliance. Written comments were required to be submitted within 30 days of the date of the email. All such comments received by the District as of the date of this report were considered prior to the preparation of the attached list. Any additional comments received prior to the actual publication of this list in the newspaper will also be considered and may result in removal or modification of those IUs listed on pages 1 to 4 of Attachment 1.
A summary of the significant noncompliance publication list for calendar years 2021, 2022, 2023, and 2024 regarding federally mandated minimum selection criteria is provided in Attachment 2.
Respectfully Submitted, Edward W. Podczerwinski, Director of Monitoring and Research, EWP:JW:CT
