ACTION:

Notice of tentative approval.

SUMMARY:

Notice is hereby given that the State of Oklahoma is revising its approved Public Water System Supervision (PWSS) program. Oklahoma has adopted the Revised Total Coliform Rule (RTCR) by reference under Title 252 Chapter 631 Subchapters 1-3 of the Oklahoma Administrative Code Pertaining to the Oklahoma Department of Environmental Quality Pubic Water Supply Operation. EPA has reviewed and approved the RTCR primacy application submitted by Oklahoma. Therefore, EPA intends to approve this PWSS program revision package, which gives the Oklahoma Department of Environmental Quality primary enforcement responsibility for implementing the Revised Total Coliform Rule for all public water systems regulated by the state.

All interested parties may request a public hearing. A request for a public hearing must be submitted by December 2, 2015 to the Regional Administrator at the EPA Region 6 address shown below. Frivolous or insubstantial requests for a hearing may be denied by the Regional Administrator. However, if a substantial request for a public hearing is made by December 2, 2015, a public hearing will be held. If no timely and appropriate request for a hearing is received and the Regional Administrator does not elect to hold a hearing on his own motion, this determination shall become final and effective on December 2, 2015. 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.
