The nation's newest multimillionaire has yet to come forward, but lottery officials revealed on Tuesday that a $310.5 million Powerball ticket was sold at a gas station in Three Rivers, Michigan.

Wednesday's jackpot was the second-largest this year, after players in North Carolina, Puerto Rico and Texas split a $564.1 million prize in February, the Associated Press noted. The golden ticket traded hands at a Shell station in the St. Joseph County town of fewer than 8,000 inhabitants, which sits 150 miles west of Detroit.

Liz Smith, one of the gas station's employees, told Kalamazoo, Michigan CBS affiliate WWMT that the revelation was bound to rock the community.

"It's crazy that it would be here in small town Three Rivers," she said. "Someone winning some $300 million - it's just crazy to think!"

If the holder of Wednesday's winning ticket claims the prize, he or she will become the winner of the second largest Powerball jackpot in Michigan history, MLive detailed. Donald Lawson, another resident of the Great Lakes State, took home a $337 million Powerball jackpot on Aug. 15, 2012, the website recalled.

Meanwhile, it is not unusual for winners to get some things in order before they get in touch, Michigan Lottery spokesman Jeff Holyfield told NBC News.

"The winner or winners would need to contact us during business hours, which are 7:45 a.m. to 4:45 p.m.," Holyfield detailed in an email. But the "last big winner we had didn't contact us for a month so she could line up a financial planner [and] lawyer," he added.

The $310.5 million jackpot, while significant, does not list among the top 25 U.S. lottery wins on record. The ranking is topped by a $656 million Mega Millions win in 2012 that was shared by three winners and is believed to be the largest cash payout in world history. The largest Powerball jackpot, meanwhile, goes back only one year, when a Florida woman scored a $590.5 million prize.
