If a responsible party or guarantor fails to inform the President, within 5 days after receiving notification of a designation under subsection (a), of the party’s or the guarantor’s denial of the designation, such party or guarantor shall advertise the designation and the procedures by which claims may be presented, in accordance with regulations promulgated by the President. Advertisement under the preceding sentence shall begin no later than 15 days after the date of the designation made under subsection (a).
