National Contingency Plan (NCP)
The National Oil and Hazardous Substance Pollution Contingency Plan (NCP) is the regulation that implements CERCLA and the Oil Pollution Act under the response program. It provides the blueprint for responding to both oil spills and hazardous substances releases.

Subpart O
The Subpart O regulation applies to CERCLA-authorized grants to States. It complements EPA's general financial assistance regulation and establishes requirements for Superfund cooperative agreements and Superfund States Contracts (SSCs) that are specfic requirements under CERLCA. This regulation outlines use and payment of state cost sharing requirements in the Superfund program.

All Appropriate Inquiries
The All Appropriate Inquiries regulation establishes federal standards for the conduct of all appropriate inquiries into previous ownership, uses and environmental conditions of a property for purposes of qualifying for certain landowner liability protections under CERCLA.
