§ 13.11 Interest, penalty and administrative costs.
(a) Interest. EPA will assess interest on all delinquent debts unless prohibited by statute, regulation or contract.
(1) Interest begins to accrue on all debts from the date of the initial notice to the debtor. EPA will not recover interest where the debt is paid within 30 days of the date of the notice. EPA will assess an annual rate of interest that is equal to the rate of the current value of funds to the United States Treasury (i.e., the Treasury tax and loan account rate) as prescribed and published by the Secretary of the Treasury in the Federal Register and the Treasury Fiscal Requirements Manual Bulletins, unless a different rate is necessary to protect the interest of the Government. EPA will notify the debtor of the basis for its finding that a different rate is necessary to protect the interest of the Government.
