ONEOK's Oklahoma Natural Gas Company Division to Implement New
Rates 


TULSA, Okla., July 26  /PRNewswire-FirstCall/ -- ONEOK, Inc. (NYSE:OKE)
announced today that its Oklahoma Natural Gas Company division will implement
new rates for its approximately 820,000 customers beginning July 28, 2005, in
accordance with state statutes.

Oklahoma law provides that a utility that has initiated a rate review by the
Oklahoma Corporation Commission may implement new rates at the end of a 180-day
period in the absence of a final order.  Oklahoma Natural Gas Company filed an
application for a rate increase with the Commission last January, seeking $99.4
million in additional annual revenue.  The 180-day period ends July 27, 2005.

The Oklahoma Corporation Commission administrative law judge who heard the case
has recommended an increase in annual revenues of approximately $58 million. 
The rates that the company will put into effect will be based on that amount. 
However, the administrative law judge's recommendation has been appealed to the
full, three-member Commission by the company and the Oklahoma Attorney General.

"While we are pleased that the administrative law judge recognized the
legitimate need for us to continue to invest in our natural gas distribution
system on behalf of our customers, we believe the facts supported a higher
revenue increase," said Oklahoma Natural Gas Company President Phyllis Worley.
Oklahoma Natural's base rates for service were last increased in 1995.  The
appeals are scheduled to be heard by the Commission on August 1.

The company estimates that a typical residential customer's monthly bill will
increase by an average of $5.75 under the new rate structure.  Oklahoma
Natural's service and delivery charges have been simplified, and customers will
now have a choice of rate plans.  Each customer will be assigned initially to
one of two rate plans, depending upon the previous history of natural gas
consumption.  Customers will have the option to change plans if they wish to do
so.

At the request of the Commission, the company plans an extensive communications
effort to inform customers about the new plans and their options.
