Superfund 104(e) Information Request Questions by Category

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.

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.
