Only players that are national born United States citizens with both parents of Caucasian race are eligible to play in the league, he said.
The plans for an all-white team have been met with shock and outrage - especially in Augusta, GA - where Lewis wants to field a team.
"Apparently, it's not a hoax - it's serious," Augusta Mayor Deke Copenhaver told FOX News Radio. "To me the idea is ludicrous. I don't think there is anyone in the city of Augusta that would want to be associated with it."
Lewis denied claims by critics that he is a racist. "If I was a true racist, I wouldn't allow Jews - Catholics - I wouldn't allow any of these people."
Lewis said he just wants to provide an alternative to the National Basketball League and what he calls their "street ball" mentality." He said he was especially put-off by a recent gun incident involving NBA star Gilbert Arenas.
"There's no excuse for guns in locker rooms, players going into the stands after fans," he said. "The style of game in the NBA is not conducive to white players."
But his basketball league may not be conducive to southern cities. The league wants to field teams in places like Chattanooga. Richard Beeland is a spokesman for Mayor Ron Littlefield. He said the league had not made any official overtures to the city.
"I don't know if this is real or not. If it's a hoax, it's done in incredibly bad taste," he told FOX News Radio. "And if it's real, it's absolutely ridiculous and something we would not want to be a part of."
Lewis said his league is indeed - real. He said games will be played in the summer. However, he acknowledged no arenas have been booked, no players have been recruited and no one has forked over the $10,000 required to own a team.
In his version of a perfect world, Lewis said he one day hopes an all-black or all-Hispanic team will compete against his Caucasians. "Let's face it," he said. "People do have allegiances to their own ethnic group. Am I right or wrong?"
