Emergency Response Equipment Inventory Act of 1989

Emergency Response Equipment Inventory Act of 1989 - Amends the Federal Water Pollution Control Act to direct the National Response Center (NRC) to establish, maintain, and annually revise a nationwide computerized listing of emergency response resources which are available to, and appropriate for use by, the National Response Team (NRT) in responding to: (1) discharges and substantial threats of discharge of oil which are within the scope of the National Oil and Hazardous Substances Pollution Contingency Plan; and (2) releases and substantial threats of release of hazardous substances, pollutants, and contaminants within that scope.

Directs the NRC to provide continuous access to such information to regional response teams and centers, on-scene coordinators, and all State and local government officials responsible for directing responses to such discharges or releases.

Requires the head of each Federal agency having a representative on the NRT to ensure that all such individuals have ready accessibility to all relevant, unclassified data.

Directs the President to take such actions as may be necessary to encourage appropriate international organizations to establish an international inventory of emergency response resources.
