01-22993. Public Water System Supervision Program Revision for the State of Oklahoma

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of proposed approval.

SUMMARY:

Notice is hereby given that the State of Oklahoma is revising its approved Public Water System Supervision Program. Oklahoma has adopted an Interim Enhanced Surface Water Treatment Rule to improve control of microbial pathogens in drinking water, including specifically the protozoan Cryptosporidium, and a Stage 1 Disinfectants/Disinfection Byproducts Rule, setting new requirements to limit the formation of chemical disinfectant byproducts in drinking water. Oklahoma has also adopted drinking water regulations requiring consumer confidence reports from all community water systems, and has administrative penalty authority in accordance with the Safe Drinking Water Act as amended in 1996. EPA has determined that these revisions are no less stringent than the corresponding federal regulations. Therefore, EPA intends to approve these program revisions.

All interested parties may request a public hearing. A request for a public hearing must be submitted by October 15, 2001 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 October 15, 2001, 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 October 15, 2001. 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.

ADDRESSES:

All documents relating to this determination are available for inspection between the hours of 8 a.m. and 4:30 p.m., Monday through Friday, at the following offices: Oklahoma Department of Environmental Quality, Water Quality Division, Public Water Supply Section, 707 North Robinson, Oklahoma City, Oklahoma 73101; and United States Environmental Protection Agency, Region 6, Drinking Water Section (6WQ-SD), 1445 Ross Avenue, Suite 1200, Dallas, Texas 75202.
