Round 3-9: Delete Clean Parcels from the NPL

Reform Description
Building on Reform 2-4d, Clarifying NPL Sites, this reform encourages EPA Regions to delete from the NPL portions of sites that are clean and available for productive use.

Listing a property on the NPL may affect the value of that property and the surrounding area -- whether or not all of the property or adjacent property is contaminated. To help encourage redevelopment, EPA is working to provide the Regions with the flexibility to clarify uncontaminated areas of NPL sites.

As part of this initiative, EPA has produced guidance that outlines the procedures for issuing assurances, followup consultation, and coordination concerning uncontaminated areas (see Documents below). EPA has also developed tools such as the "Soil Screening Guidance" (see Reform 2-8 Documents) to identify portions of sites that do not warrant Federal attention.

This reform aims to:
  • Map and track partial deletions at NPL sites; and
  • Facilitate redevelopment of uncontaminated portions of sites.

Reform Status
check mark Implementation of this reform is complete.

EPA continued to promote the use of partial deletions at NPL sites.

[Back to Top]

EPA issued a policy change to allow partial deletions in November 1995, and signed the "Procedures for Partial Deletions at NPL Sites" on April 30, 1996 (see Documents below). The latter guidance does not outline partial deletion procedures, as they are identical to deletion procedures for entire sites. More recently, the January 2000 "Close Out Procedures for National Priorities List Sites, Chapter 6 - Partial Deletion" further delineated the process and documentation necessary for partial deletions.

As of May 2001, clean parcels were deleted at 23 NPL sites (listed below), and notices of intent to delete clean parcels were issued at three other sites.

The links provided below point to Regional NPL Fact Sheets. You may also want to check the OSRTI partial deletions page for the most current list of partial deletions, with links to NPL site narratives and Federal Register notices.

Success Stories
Commencement Bay, Nearshore/Tideflats, Tacoma, WA

Cleanup progress in several areas of the Commencement Bay, Nearshore/Tideflats site eliminated the threat to public health or the environment and allowed EPA Region 10 to publish a Notice of Intent to Delete in the August 28, 1996, Federal Register. The first partial site deletion was completed on October 29, 1996. Sections of the original site now have great potential for economic redevelopment. [FY97 Success]
