site was once farm land, and was then left vacant while owned by
Ithaca College. It became home to National Cash Register (which
became known as NCR) from 1953-1992 and was eventually part of AT&T
Global Information Systems, Axiohm IPB, and finally, TPG IPB. The
current owners are developing the site as a multi-tenant commercial
operation with possible uses by light industrial firms. The
new owners have applied for assistance under the NYSDEC
Brownfields Cleanup Program (BCP).
Site Assessments performed in 2003 (referenced in the documents
below) found a wide variety of chemicals present in soil samples
and groundwater monitoring wells. Floor drains in the facility were
connected to the storm sewer and had been used for heat treat equipment
wash water. The continuing presence of chemicals in and around the
"NCR Sewer" leading downhill (to South Aurura Street and
the lower South Hill neighborhoods) from this site is not surprising.
first three documents are the 2081 pages of the 2005 initial Brownfields
Cleanup Program Application for the South
Hill Business Campus.
I has the formal application and a few of the attachments:
II has various environmental reports, the Source Investigation
Report, and the Phase I Environmental Site Assessment:
III has the Investigative Work Plan.
May 2006, owners of the South Hill Business Campus brought a lawsuit
against NCR Corporation for costs of site cleanup and damages, according
to an article in the Central
New York Business Journal (no longer online).
two documents on the continuing efforts toward remediation as a
Brownfields site were both released in December 2007:
Remedial Investigation Report
Remedial Work Plan
Work Plan for SHBC was released in March 2008. The DEC also
released this Fact
Sheet on the planned remedial actions. In-situ
chemical oxidation (ISCO - injection of potassium permanganate into a matrix
of points on the surface of contaminated soil) started in late June
and should be completed in early August.
A Remedial Design document was released in June 2008, describing the plans for the in-situ chemical oxidation at the South Hill Business Campus. This document is available here:

Report Text Sections
In April 2009, the DEC released a "Final Immediate Soil Vapor Investigation and Vapor Intrusion Summary Report" for the Axiohm cleanup project, which concentrates primarily on the offsite testing of soils and structures around the sewer lines running on South Hill. This report is descussed in the Sewers section of this website.
The report summarizes the 2008 activities on the SHBC site:
In November 2008, S&W Redevelopment of North America, LLC issued a Final Engineering Report on behalf of the South Hill Business Campus, LLC for BCP Site No. C755012. The report documents the implementation of remedial activities conducted at the site completed through September 2008. The objective of the remedial activities was to achieve Track 4 cleanup levels under the NYSDEC BCP (Title 14 Section 27-1415), which relies on institutional and engineering controls consistent with the proposed commercial end use.
Remedial actions implemented at the site included the excavation and removal of soil adjacent to the two former 9,000 gal underground dilution tanks, injection of 4,958 lbs of potassium permanganate, and 13,600 gal of solution into 10 injection trenches west of the southern portion of the site building. In addition, under an IRM a sub-slab depressurization system was installed in the on-site building to mitigate potential soil vapor intrusion.
The first tests (January 2009) of air and groundwater at the former NCR/Axiohm site (now called the South Hill Business Campus) have been released. The report is 1.9MB and is here. The results show lower toxins levels at many of the test points are lower, some significantly. Results in seven wells "do not yet show a significant decrease in VOC levels." Test wells along the storm sewer adjacent to the Main Building still show high levels of TCE:
IOW-1: 2700 ug/m^3 TCE
IOW-3: 1200 ug/m^3 TCE
MW-7: 2800 ug/m^3 TCE
The second round of tests (5 MB report here) doesn't show much improvement:
IOW-1: 2800 ug/m^3 TCE
IOW-3: 7700 ug/m^3 TCE
MW-7: 7400 ug/m^3 TCE
The reports suggest that seasonal variations at this site are considerable, so we'll need to wait for the release of the July 2009 tests to see how different they are. Thanks to Karen Cahill of the NYSDEC for providing electronic copies of this information.
