Superfund: Collection of Questions for CERCLA Section 104(e) Information Requests
Under section 104(e) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, commonly referred to as Superfund), EPA is authorized to seek information involving sites containing hazardous substances. Early in the cleanup process, EPA conducts a search to find all of the potentially responsible parties (PRPs). EPA looks for evidence to determine liability by matching wastes found at the site with parties that may have contributed wastes to the site. EPA uses many approaches to do this research, including the use of "information request letters" to gather information.
With input from the Agency's regional offices, EPA compiled into 36 categories sample questions for information request letters tailored to the
- type of site (e.g., chemical plants, dry cleaners),
- sophistication of the recipient (e.g., individual, small business, large corporation),
- recipient's involvement with the site (e.g., owner, operator, transporter),
- nature of the information sought
- insurance coverage, and
- Superfund Recycling Equity Act (SREA)
The collection of questions by specific categories is intended to assist the Regions in tailoring specific information requests based on the type of potentially responsible party and their involvement at a site.
These sample questions are used at the Regions' discretion.
Additional information on information requests is available for the Superfund policy and guidance database's information requests category.
