According to Michael Grunberg, managing principal of Grunberg Realty, in N.Y.C., the company has closed on the Somerset Refinery and associated business units. This closing could not have been effected without the involvement of congressman Hal Rogers, senators McConnell and Bunning and many others. They're dealing with the EPA and the EPA's eventual understanding of the nature of the circumstances surrounding this purchase allowed this closing to occur. The acquisition includes the 105-acre oil refinery on 600 Monticello St., several office buildings, a fleet of tanker trucks and 12 retail gas stations in the state.
