Mission Statement

ABAC looks for connections between public and private stakeholders to provide societal comfort and confidence that institutional controls and engineering controls are maintained in perpetuity and protective of human health in a cost effective manner.

Assuring Federal Protection Against Cleanup Costs

All Appropriate Inquiry Alone Does Not Afford Federal Liability Protection

Many property owners have been led to believe, upon completion of their All Appropriate Inquiry (AAI) prior to purchasing a piece of commercial property, that they will enjoy federal liability protections under the Brownfield Amendments to Superfund/CERCLA.  Yet, the Brownfields Amendments clearly require that such owners satisfy their "continuing obligations" in order to maintain their federal liability protection.

American Brownfields Assurance Company, Inc. and the Sentinel Stewardship Companies, are uniquely positioned to work together with property owners to provide resources and tools that property owners might utilize to satisfy their continuing obligations under the Brownfields Amendments and to secure federal liability protection.
