Growth in one of the biggest cities in the Hill Country could come to a screeching halt if a new rock crushing quarry moves forward.

That's according to city officials in Marble Falls, who filed a motion to the Texas Commission on Environmental Quality stating they “stand to lose well over a billion dollars in projected ad valorem tax revenue” if TCEQ gives the quarry a standard air quality permit.

A billion dollars.

Despite Marble Fall’s appeal to the TCEQ, the executive director of the TCEQ granted the permit to Asphalt Inc.: an Austin-based LLC.

Now, the City of Marble Falls has filed an appeal to the TCEQ, and earlier this week the city council approved moving forward with a lawsuit in district court against TCEQ.

So far, no lawsuit has been filed.

People in Marble Falls are concerned about the new quarry, which would be located outside city limits, off of U.S. 281 near Flat Rock Road in Burnet County.

There are plans to build a development not far from the site, and the Baylor Scott & White Medical Center is less than three miles away from the site as well.

"Everybody's been up in arms. I've got customers coming in complaining. Nobody wants this,” said Marble Falls business owner Kim Kirkland.

Kirkland owns Ciao Bella, and fears air quality concerns from the rock crushing plant could damage the local economy.

"They (tourists) come for the lake, and the water and Horseshoe Bay and golf,” said Kirkland. “We have to keep it clean or it'll kill the town."

According to city officials, Asphalt Inc. still needs several permits before it can open in 2018. They are currently working on plans for litigation to stop the plant from opening.
