Explanation of types of sites in this database

Federal Superfund:  Sites on the National Priorities List,which are determined to pose the most significant potential threat to human health due to their known or suspected toxicity and potential for human exposure.

Federal RCRA: Related to the Superfund program, Resource Conservation and Recovery Act program focuses only on hazards at active facilities - it does not address abandoned or historic sites.  It is possible for a Superfund site to be located at an active RCRA facility and, in such cases, the site would be managed under RCRA because it is an active facility.

State, class 1: The classification assigned to a site at which contamination constitutes a significant threat to public health and the environment; and the significant threat to public health and the environment is causing, or presents an imminent danger of causing, either irreversible or irreparable damage to the environment.

State, class 2: The classification assigned to a site at which the disposal of hazardous waste has been confirmed and the presence of such hazardous waste or its components or breakdown products represent a significant threat to the environment or to health; or hazardous waste disposal has not been confirmed, but the site has been listed on the Federal National Priorities List (NPL).

State, class 3: The classification assigned to a site at which contamination does not presently constitute a significant threat to public health or the environment.  This classification is used only when there is sufficient information available to conclude that the site does not pose a significant threat. This classification is not used for sites where the information is insufficient to make a definitive decision concerning significant threat.

State, class 4: The classification assigned to a site that has been properly closed but that requires continued site management, consisting of operation maintenance, and monitoring. A site whose remedial program stipulates more than one operable unit is eligible for this classification only when all of the operable units have been satisfactorily completed. Under certain circumstances, this classification may be assigned to a site where remedial activities have been completed, but conditions at the site have not been brought into compliance with applicable regulatory standards.

State, class 5: The classification assigned to a site that has been properly closed in a setting where a consequential amount of hazardous waste or its constituents remain, but do not require continued operation, maintenance and/or monitoring. No further action required.

State, class A: The classification assigned to a non-registry site in any remedial program where work is underway and not yet complete (i. e., Brownfield Cleanup Program, Environmental Restoration Program, and Voluntary Cleanup Program sites). This may be used for Manufactured Gas Plant sites or those being remediated under an EPA Cooperative Agreement.

State, class C: The classification used for sites where the state has determined that remediation has been satisfactorily completed under a remedial program (i. e., State Superfund, Brownfield Cleanup Program, Environmental Restoration Program, Voluntary Cleanup Program). State Superfund (Registry) sites must have completed all active operation, maintenance, or monitoring requirements before they can be delisted and made class C.
