Except as provided in subsection (b), all claims for removal costs or damages shall be presented first to the responsible party or guarantor of the source designated under section 2714(a) of this title.
If a claim is presented in accordance with this section, including a claim for interim, short-term damages representing less than the full amount of damages to which the claimant ultimately may be entitled, and full and adequate compensation is unavailable, a claim for the uncompensated damages and removal costs may be presented to the Fund.
