R.I. Gen. Laws § 23-19.14-6.1: Liability for releases of petroleum.

Responsible parties for releases of petroleum are defined as all parties who are otherwise liable for an actual or threatened release of petroleum under any other applicable statute, rule, or common law. This section shall neither be construed as establishing new liabilities or obligations for parties responsible for releases of petroleum that do not otherwise exist under statute, rule, or common law, nor as diminishing any liabilities or obligations that may be established by those provisions. Accordingly, the obligations of the responsible parties for releases of petroleum shall be the same as those provided for under any other application, provisions or rules of law.
