Title: Montana National Priority List Site Boundaries, 1999

Abstract:

The National Priority List is EPA's published compilation of the rankings of Superfund Sites. A site must be added to the List before Superfund Trust Funds can be expended for remediation. The points in this data set represent the functional extent of each NPL site as defined by the Record of Decision or the Remdial Project Manager or Principle Responsible Party.

Purpose:

These data were published in the Montana State Library Digital Atlas web application between 2001 and 2014 and have been removed because they are out of date. Of the 164 sites in the EPA database, 15 Montana sites were selected.

Originator: ISSI contractor to EPA
Publication date: 1995
Title: 1995 npl sites
Source contribution:: This was the primary base used to revise the locations and boundaries
Calendar date: 1995

Process step: copied 1994 NPL coverage from ISSI

Process step:

Revisions were made based on information supplied by the Remedial Project managers, DRG base maps at 1:24000 scale and/or The Superfunds records center provided legal descriptions for some sites

Process step: The data was plotted at the site level
