The NPL is intended primarily to guide the EPA in determining which sites warrant further investigation.

  • New Proposed NPL Sites & New NPL Sites - Documents for the most recently proposed NPL sites and recently added NPL sites, including: Documentation Records, Site Listing Narratives, Support Documents and other supporting documentation.
