WALHALLA — Oconee County officials are poised to hear a proposal next month from an unidentified industrial company looking to receive tax breaks for a $10 million expansion that would bring an undetermined number of new jobs, Economic Development Commission (EDC) members learned Friday.

A first reading of a fee-in-lieu of tax agreement between the mystery company — code-named “Project Boomer” — should go before the Oconee County Council in September, EDC Director Jim Alexander said during the group’s regular monthly meeting.

Alexander mentioned Project Boomer while reviewing a list of investments totaling $134.7 million (including Project Boomer if the deal goes through) made by local industrial companies in 2007 and 2008 that have produced 555 jobs.

Alexander’s chart did not show Project Boomer generating jobs, but he assured there would be some. “There will be some jobs with that but I can’t get you numbers now.”

EDC officials are hoping to generate more business as they forge ahead with plans to add a new 50,000-square-foot speculative building on 15-acres still available at the S.C. Highway 11 Commerce Center in Westminster.

Product and Infrastructure Committee Chairman Harold Gibson said engineers continued work on preparing the way for a spec building at the Commerce Center. County Council supports constructing a spec building but have not decided how to pay for it.

EDC Chairman Hank Field said having a product to show companies is a proven method of attracting new business.

EDC officials also are excited about the prospects for developing new Golden Corner Commerce Park in Fair Play. The project, long regarded as a key to development along the Interstate 85 corridor in Oconee, got a big boost this week with the council’s commitment to spend $3 million to $4 million on getting an expandable 50,000-gallon-a-day wastewater treatment plant at the proposed industrial park.
