(2) The location, date, and time of the incident;

(3) The type and quantity of oil involved;

(4) The date of the designation;

(5) The procedures for accepting or denying the designation; and

(6) The name, address, telephone number, and, if available, telefax number of the responsible Federal official to whom further communication regarding the incident, advertisement of the incident, or denial of designation should be directed.
