Gov. George Deukmejian filled the vacant fifth seat on the Public Utilities Commission Thursday, naming a staff assistant, John B. Ohanian of Fresno, succeeding Victor Calvo of Mountain Hill, whose six-year term expired last Dec. 31.
Ohanian, 49 and a Republican, has been chief deputy director of Deukmejian's office of planning and research since 1983. Before that he was a PUC representative in Fresno. He joined the commission as a transportation engineer in 1969.
The nomination, subject to confirmation by the Senate, brings the PUC to full strength, with four of the five seats now filled by Deukmejian appointees. Only Commissioner Donald Vial, whose term has two years to run, remains from the Administration of former Gov. Edmund G. Brown Jr., whom Vial also served as director of industrial relations.
