Abstract

Notice is hereby given that the Environmental Protection Agency (EPA) has approved the State of Indiana's revisions to its Public Water System Supervision (PWSS) Program under the federal Safe Drinking Water Act (SDWA) for revisions to four National Primary Drinking Water Regulations (NPDWRs): the Ground Water Rule (GWR), Lead and Copper Rule--Short Term Revisions (LCR-STR), Long-Term 2 Enhanced Surface Water Treatment Rule (LT2 ESWTR), and the Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 D/DBPR). The EPA has determined that the State of Indiana's PWSS program regulations and the revisions thereto are no less stringent than the above corresponding federal regulations and thus give the Indiana Department of Environmental Management primary enforcement responsibility for the GWR, LCR-STR, LT2 ESWTR, and Stage 2 D/DBPR. Notice is also hereby given that the EPA has approved the State of Illinois' revisions to its PWSS program under SDWA for adoption of the Filter Backwash Recycling Rule (FBRR). The EPA has determined that the State of Illinois' PWSS Program regulations and the revisions thereto are no less stringent than the NPDWR and thus give the Illinois Environmental Protection Agency primary enforcement responsibility for the FBRR. These determinations on the Indiana and Illinois requests for approval of such primacy enforcement responsibility shall take effect in accordance with procedures described below, subject to timely substantial requests for public hearing. This approval action does not extend to public water systems in Indian Country. By approving this revision, the EPA does not intend to affect the rights of federally recognized Indian Tribes in either Indiana or Illinois, nor does it intend to limit existing rights of either the State of Indiana or the State of Illinois.

Public Water System Supervision Program Revision Approvals for 
the States of Indiana and Illinois

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of tentative.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given that the Environmental Protection 
Agency (EPA) has approved the State of Indiana's revisions to its 
Public Water System Supervision (PWSS) Program under the federal Safe 
Drinking Water Act (SDWA) for revisions to four National Primary 
Drinking Water Regulations (NPDWRs): the Ground Water Rule (GWR), Lead 
and Copper Rule--Short Term Revisions (LCR-STR), Long-Term 2 Enhanced 
Surface Water Treatment Rule (LT2 ESWTR), and the Stage 2 Disinfectants 
and Disinfection Byproducts Rule (Stage 2 D/DBPR). The EPA has 
determined that the State of Indiana's PWSS program regulations and the 
revisions thereto are no less stringent than the above corresponding 
federal regulations and thus give the Indiana Department of 
Environmental Management primary enforcement responsibility for the 
GWR, LCR-STR, LT2 ESWTR, and Stage 2 D/DBPR.

    Notice is also hereby given that the EPA has approved the State of 
Illinois' revisions to its PWSS program under SDWA for adoption of the 
Filter Backwash Recycling Rule (FBRR). The EPA has determined that the 
State of Illinois' PWSS Program regulations and the revisions thereto 
are no less stringent than the NPDWR and thus give the Illinois 
Environmental Protection Agency primary enforcement responsibility for 
the FBRR.
    These determinations on the Indiana and Illinois requests for 
approval of such primacy enforcement responsibility shall take effect 
in accordance with procedures described below, subject to timely 
substantial requests for public hearing. This approval action does not 
extend to public water systems in Indian Country. By approving this 
revision, the EPA does not intend to affect the rights of federally 
recognized Indian Tribes in either Indiana or Illinois, nor does it 
intend to limit existing rights of either the State of Indiana or the 
State of Illinois.

DATES: Any interested party may request a public hearing on this 
determination. A request for a public hearing must be submitted by 
September 8, 2026. The EPA Region 5 Regional Administrator may deny 
frivolous or insubstantial requests for a hearing. If a substantial 
request for a public hearing is made by September 8, 2026, EPA Region 5 
will hold a public hearing, and a notice of such hearing will be 
published in the Federal Register and a newspaper of general 
circulation. Any request for a public hearing shall include the 
following information: the name, address, and telephone number of the 
individual, organization, or other entity requesting a hearing; a brief 
statement of the requesting person's interest in the Regional 
Administrator's determination; a brief statement of the information 
that the requesting person intends to submit at such hearing; and the 
signature of the individual making the request, or, if the request is 
made on behalf of an organization or other entity, the signature of a 
responsible official of the organization or other entity.
    If EPA Region 5 does not receive a timely and appropriate request 
for a hearing and the Regional Administrator does not elect to hold a 
hearing upon her own motion, this determination shall become final and 
effective on September 8, 2026 and no further public notice will be 
issued.
