# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of tentative approval.

# SUMMARY:

Notice is hereby given that the State of Indiana is revising its approved Public Water System Supervision Program.  Indiana has revised its Public Notification (PN) Rule; its Lead and Copper Rule Minor Revisions (LCRMR) Rule; its Analytical Methods for Chemical and Microbiological Contaminants and revisions to Laboratory Certification Requirements; its revisions to Analytical Methods for Radionuclides Rule; and its Removal of the Prohibition on the Use of Point of Use Devices for compliance with National Primary Drinking Water Regulations Rule. 

EPA has determined that these revisions by the State are no less stringent than the corresponding federal regulations.  Therefore, EPA intends to approve these revisions to the State of Indiana's Public Water System Supervision Program.  This approval action does not extend to public water systems (PWSs) in Indian Country, as the term is defined in 18 U.S.C. 1151.  By approving these rules, EPA does not intend to affect the rights of federally recognized Indian Tribes in Indiana, nor does it intend to limit existing rights of the State of Indiana.  Any interested party may request a public hearing.  A request for a public hearing must be submitted by December 1, 2005 to the Regional Administrator at the EPA Region 5 address shown below.  The Regional Administrator may deny frivolous or insubstantial requests for a hearing.  However, if a substantial request for a public hearing is made by December 1, 2005, EPA Region 5 will hold a public hearing.  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 on his own motion, this determination shall become final and effective on December 1, 2005.  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 and 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.
