RE: Petroleum Tank Release Site File Closure
Site: Metcalf Jr. High School, 2250 Diffley Road, Eagan, MN 55122
Site ID#: LEAK00002672
Dear Mr. Hale:
Minnesota Pollution Control Agency
We are pleased to let you know that the Minnesota Pollution Control Agency (MPCA) staff has
determined that your investigation and/or cleanup has adequately addressed the petroleum tank
release at the site listed above. Based on the information provided, the MPCA staff has closed
the release site file.
Closure of the file means that the MPCA staff does not require any additional investigation
and/or cleanup work at this time or in the foreseeable future. Please be aware that file closure
does not necessarily mean that all petroleum contamination has been removed from this site.
However, the MPCA staff has concluded that any remaining contamination, if present, does not
appear to pose a threat to public health or the environment under current conditions.
The MPCA reserves the right to reopen this file and to require additional investigation and/or
cleanup work if new information, changing regulatory requirements or changed land use make
additional work necessary. If you or other parties discover additional contamination (either
petroleum or nonpetroleum) that was not previously reported to the MPCA, Minnesota law
requires that the MPCA be immediately notified.
You should understand that this letter does not release any party from liability for the petroleum
contamination under Minn. Stat. ch. 115C (2000) or any other applicable state or federal law. In
addition, this letter does not release any party from liability for nonpetroleum contamination, if
present, under Minn. Stat. ch. 115B (2000), the Minnesota Superfund Law.
If future development of this property or the surrounding area is planned, it should be assumed
that petroleum contamination may still be present. If petroleum contamination is encountered
during future development work, the MPCA staff should be notified immediately.
