Louis Pomponio Jr., the Washington-area real estate and contruction entrepreneur who was convicted of bribery, yesterday voluntarily surrendered to federal officials in Florida to begin serving a three-year prison term.

Pomponio, 45, will serve his sentence at the minimum-security prison at Eglin Air Force Base near Pensacola, Fla., a facility one federal prosecutor described as "a country club." He will be eligible for parole in one year.

Pomponio was convicted in U.S. District Court in Alexandria in connection with the payment of $320,000 and two new cars to a New York bank official in exchange for several million dollars worth of loans for the Pompanio family's Arlington-based conglomerate.

Pomponio normally would have reported to the minimum-security Allenwood, Pa. prison camp. A federal Bureau of Prisons spokesman said, however, that the agency received a letter last week from Pomponio's lawyer stating that Pomponio's family would make its permanent home in Florida and that visitation rights would be easier at Eglin.

The bureau also said it was told Pomponio suffered from hypertension and a gall bladder ailment, but the spokesman said Pomponio jogs daily and that medical care should not be a problem.

Pomponio will do landscaping work at the base, according to Assistant U.S. Attorney Frank W. Dunham.
