The OSLTF is subject to both permanent and discretionary
appropriations. Discretionary appropriations from the
OSLTF have provided funding to several agencies for oil-
spill-related activities. The permanent appropriations are
limited to a maximum of $150 million annually. Permanent
appropriations provide an immediate funding source to pay
for eligible activities, including federal response actions,
eligible claims submitted by affected parties, and natural
resource damages. The U.S. Coast Guard administers the
OSLTF through its National Pollution Funds Center.
OPA authorizes the federal government to recover
payments, including response costs and claims, made from
the OSLTF through the enforcement of liability against
responsible parties. Recovered funds are to be deposited
back into the trust fund.
