A federal grand jury has indicted a Northern Virginia business executive and an Environmental Protection Agency economist on bribery charges related to bidding for a proposed multimillion dollar EPA contract.

The indictment, returned in U.S. District Court in Alexandria, charges Fred M. Newman, vice president of Energy Resources Company Inc. of Vienna, promised jobs to two EPA employes in exchange for inside information on a proposed $3.5 million EPA contract for a household pesticide usage survey. The contract was never awarded.

The grand jury alleged one of the employes, Linda De Luise, assigned to an EPA office in Crystal City, accepted the offer of a $50,000 annual salary in July 1980 and improperly aided Newman. Assistant U.S. Attorney Thomas M. Buchanan said the second employe, Linda Zarow, also an EPA economist, was offered a $35,000-a-year job with the company but declined.

De Luise still is employed by EPA, Buchanan said.

Newman faces two counts of bribery, punishable by up to 15 years in prison and a $20,000 fine on each count. De Luise is charged with a single count of accepting a bribe and faces up to 15 years in prison and a $20,000 fine if convicted.
