The Public Service Commission is holding a public hearing in Graniteville on Wednesday over higher rates it has allowed Avondale Mills to collect from some water and sewer customers.
The system was subsidized for years by the now shuttered Avondale Mills plant. Saying it was in dire straits since the closure, the company won the higher rates in June.
Some customers' rates increased by as much as 700 percent.
In August, several state lawmakers obtained a temporary court order blocking the company from collecting on the higher rates. The company has filed an appeal challenging the order that blocks its collections.
