Yes Yes Yes Yes Yes Present in Closing Conf. Yes Yes Yes Yes No Engineer Yes No Facility/Site Description Mr. Flatebo confirmed the following facility information: The City of Chicago Heights operates a small Municipal Separate Storm Sewer System (MS4). The purpose of the inspection was to determine the status of MS4 permit coverage for the City of Chicago Heights, and to review the City's implementation of MS4 permit program requirements. The Phase II National Pollutant Discharge Elimination System (NPDES) regulations automatically cover, on a nationwide basis, any MS4 "located in an urbanized area as determined by the latest Decennial Census by the Bureau of the Census" (unless the MS4 qualifies for a waiver) 40 CFR 122.32(a)(1). "Urbanized areas," as defined by the Census Bureau when the Phase II regulations were issued, comprise areas "that together have a minimum population of 50,000 people.'' 64 Fed. Reg. 68722, 68751 (December 8, 1999). 2 of 21 City of Chicago Heights Inspection Date: September 13, 2022 The universe of regulated small MS4s in urbanized areas expands every 10 years, according to the 1999 storm water Phase II final rule. A "small MS4" is any MS4 not already covered under Phase I of the NPDES storm water program. The City of Chicago Heights is within the Chicago, IL-IN urbanized area (UACE#16264), as defined by the U.S. Census Bureau, and subject to NPDES storm water regulation as a small MS4.

Streambank Maintenance Completed in 2022, approximately 3,900 linear feet of existing streambank was rehabilitated including removal of non-native species, tree removal, reshaping of side slopes, planting native prairie seed mixes and replacement of 10'W x 4'H concrete box culvert.

The existing approximately 5,240 linear feet of storm sewers were televised and cleaned in 2021. A follow-up project, with construction beginning in fall 2022, will construct new 43" x 76" arch pipe on Enterprise Road and into the existing detention basin; and a new 3' x 5' box culvert between 575 and 579 Saratoga Drive to replace a collapsed CMP arch pipe. Chicago Road Culvert Replacement Illinois Department of Transportation (IDOT) recently replaced the existing culvert under Chicago Road at Thorn Creek Tributary adjacent Bloom High School with a new triple 12' x 6' box culvert. 4 of 21 City of Chicago Heights Inspection Date: September 13, 2022 Dixie Highway Culvert Replacement IDOT is planning a similar culvert replacement project to the Chicago Road Culvert Replacement project on the Thorn Creek Tributary under Dixie Highway adjacent the west side of Bloom High School near Hawthorne Lane. The project is currently being designed by IDOT and is expected to be constructed within the next 3 to 5 years.

Thorn Creek TMDL_2021.01.pdf Location: Streets Department Warehouse Observation #: TF2-OB-001 Date: 09/13/2022 Following the opening conference, EPA inspectors begin the field portion of the inspection. They were accompanied by Mr. DelValle and Mr. Straczek. Mr. Caruso and Ms. Maertens-Pizzo left City Hall and concluded their participation in the inspection. Within the Streets Department warehouse there are multiple floor drains and a variety of equipment including municipal vehicles, a vacuum truck, and a power washer. Mr. Straczek clarified the following points regarding warehouse activities: -All the drains within the warehouse are storm drains, they not connected to the sanitary sewer; -The power washer is used to remove ice and salt from equipment during winter. The wash water is disposed of via the interior flood drains; -The vacuum truck is only used to remove storm water. If there is sanitary waste that needs to be removed, the City contracts out the work to a company that has their own vacuum truck; and 5 of 21 City of Chicago Heights Inspection Date: September 13, 2022 -No waste oil is generated within the warehouse. The City sends the vehicles out for preventative maintenance. Photo(s) 1.
