All payments for work or services performed or to be performed
under this Act shall be deposited in a separate account or accounts
which may be used to pay directly the costs of such work or
services, to repay or make advances to appropriations or funds
which do or will initially bear all or part of such costs, or to
refund excess sums when necessary: Provided, That said receipts may
be credited to a working capital fund otherwise established by law,
and used under the law governing said funds, if the fund is
available for use by the agency of the Department of Commerce which
is responsible for performing the work or services for which
payment is received. Acts appropriating funds to the Department of
Commerce may include provisions limiting annual expenditure from
said account or accounts.
