The biodiesel production plant is located in Cleburne, Texas and can generate 12 million gallons fuel per annum.
Subsequent to the purchase, Delek will invest an additional $3m to improve feedstock flexibility at the facility.
Biodiesel currently produced at the plant is procured by Delek and its facilities under a tolling agreement that will terminate once the acquisition closes by 23 January 2013.
Delek US chairman, president and CEO Uzi Yemin remarked that the company has a net cash reserve of $240m to undertake further expansions.
"This acquisition further integrates our operations by improving our feedstock flexibility for blending biodiesel at our Tyler refinery.
"We will continue to explore opportunities to grow our business and return value to our shareholders during 2013," said Yemin.
