This is a summary of recent congressional actions not reported elsewhere in The Post. HOUSE Embassy Security

The House approved, 389 to 7, a measure that would provide $4.1 billion to enhance security at embassies and consulates around the world and to provide cash payments for Americans taken hostage by terrorists. The bill applies to all Americans taken captive since 1979, including those seized at the U.S. Embassy in Tehran. Hostages would be eligible for payments of $66 per day of captivity, which would give the Tehran hostages $29,301 apiece (HR4151; March 18) Coast Guard

A Merchant Marine and Fisheries subcommittee approved legislation authorizing fiscal 1987 funds for the Coast Guard. The measure provides almost $1.9 billion for operating expenses, $300 million for procurement and construction, $35 million for research and development and such sums as necessary for retirement benefits.

The bill authorizes $187 million less than fiscal 1986 and over $252 million more than the administration's request. The bill also includes guidelines for contracting out certain Coast Guard services and a build-American provision for major components of new Coast Guard vessels.
