WASHINGTON. D.C. -

U.S. Senator Bob Casey is encouraging Stone Brewing Company to build a new plant in the Lehigh Valley.

On Monday, the Pennsylvania Democrat sent a letter to to Greg Koch, CEO and co-founder of Stone Brewing, urging him to bring the plant to this area.

“Our region’s workforce is highly skilled and I’m confident any company would benefit from locating in the state," said Casey in a news release.

The senator reported both Allentown and Bethlehem have expressed interest in becoming the new home of the plant, which Stone plans to build somewhere in the eastern United States.

"Companies like Stone Brewing represent a growing industry that could boost economic growth and job creation in Pennsylvania for years to come,” said the senator.

Casey's letter to the Escondido, California-based company states that Stone recently published a request for proposal to open a location in the eastern half of the United States.

"I understand that Stone Brewing Company produces outstanding, unique beers while maintaining an unwavering commitment to sustainability, business ethics, and the art of brewing," wrote Casey.

"I am further informed that Stone Brewing has been rated as one of the top breweries in the country by several publications."

Casey is a cosponsor of legislation, the Small Brew Act, which would reduce excise taxes on small brewers.

In his letter, Casey cited the strength of the region’s workforce in making the case for the Lehigh Valley.  He also stressed that "Pennsylvania is home to a proud and rich brewing history that continues to expand."
