OPA meaning in Governmental ?

The Oil Pollution Act of 1990 (OPA) (101 H.R.1465, P.L. 101-380) was passed by the 101st United States Congress and signed by President George H. W. Bush. It works to avoid oil spills from vessels and facilities by enforcing removal of spilled oil and assigning liability for the cost of cleanup and damage; requires specific operating procedures; defines responsible parties and financial liability; implements processes for measuring damages; specifies damages for which violators are liable; and establishes a fund for damages, cleanup, and removal costs. This statute has resulted in instrumental changes in the oil production, transportation, and distribution industries.
