Topeka ? The Kansas Lottery still has no proposals from developers for building a state-owned casino in the state’s southeast corner, and has set a new application deadline of April 21.

The deadline was set to expire Thursday, but the Lottery Commission agreed to extend it even though state officials aren’t expecting any proposals to emerge.

The deadline has been extended multiple times since September 2008, when Pennsylvania-based Penn National Gaming Inc. dropped plans for a casino in Cherokee County.

Penn abandoned the project after the Quapaw Tribe opened a casino just across the state line in Oklahoma. Many Kansas officials now believe a state law requiring a developer to invest $225 million in the project prevents it from being economically viable.
